How to disable the VAZ-2115 immobilizer yourself

In this article, auto electrician Alexey Molotov answers the question “Where is the VAZ 2114 immobilizer located?”

The VAZ 2114 immobilizer is an anti-theft device designed to protect the car from theft. If the car is broken into and when you try to start the engine, the immo will activate the engine blocking to prevent movement in the car. For what reasons the immobilizer may fail and how to disable it yourself, we will tell you in this article.

How to disable the immobilizer on a VAZ-2114

Disabling the immobilizer on a VAZ-2114 may be necessary in several cases:

  • there is a need for a more advanced anti-theft system (for example, equipped with auto start);
  • if the immobilizer is full of “software junk,” the control unit fails;
  • the car has a device with an anti-theft function that has a manufacturing defect;
  • the blocking system generates an error as a result of the battery being completely discharged;
  • There was a sudden blocking of the standard anti-theft system.

There are several ways in which you can disable the immobilizer on a VAZ-2114 without any problems.

The first method is to physically disable the immobilizer. To do this, we perform several simple steps:

  • remove the connector from this anti-theft device;
  • We put a jumper for diagnostics.

The second method is to take the engine control unit to a service center or go there by car, and qualified specialists will deal with the control unit. Typically, disabling the standard anti-theft system takes about fifteen minutes.

The third method is to disable the control unit on the immobilizer yourself. To do this, you should follow these instructions:

  1. Find the electronic control unit (ECU) of the anti-theft device (it may be located inside the center console).
  2. Remove the signal wire connector from the ECU.
  3. Count the ninth and eighteenth contacts (out of twenty available).
  4. Cut off the ninth and eighteenth contacts of the wiring - from the block at a distance of four to five centimeters.
  5. Strip the ends of the cut contact wires.
  6. Twist the ends of the cut wires.
  7. Insulate the twisted ends of the wires (this action will restore the diagnostic line, and the immobilizer will stop transmitting its data to the electronic control unit).
  8. Reinstall the connectors in their original places.

This method is simple even for a novice car enthusiast, but it cannot always correctly disable the standard anti-theft device.

The fourth method is to reflash the electronic control unit of the standard immobilizer on the VAZ-2114. Of course, it is best to entrust such an operation to qualified specialists from the service center. But if the vehicle owner does not have such an opportunity, then you can try to reflash the anti-theft device ECU yourself at home. The term “reflash” itself means erasing all information about this device from the memory of the electronic control unit. To do this you need to prepare the following tools:

  • special software;
  • computer;
  • soldering gun or soldering station;
  • microcircuit programmer.

After we have prepared the necessary tools, we move on to specific actions:

  1. We dismantle the electronic engine control unit, to which the standard immobilizer from the passenger car is connected.
  2. Open the back cover of the ECU.
  3. We find the required microcircuit that is responsible for the registered data about the anti-theft device (you can read about what kind of circuit this is in the corresponding instructions for the device).
  4. We unsolder the old microcircuit.
  5. Choose one of the options for the next step:
      or solder in a new microcircuit;
  6. or we clean an existing microcircuit using a Windows computer and a special program for resetting the memory of microcircuits.
  7. We physically disable the immobilizer so that the ECU memory does not record new information about it.
  8. We install the re-flashed electronic control unit on the car again.

This method is more painstaking, but it is distinguished by its effectiveness. But this only completed the immobilizer flashing operation; it will still need to be reprogrammed using a “learning” red key. And only after this can you officially disable the standard anti-theft device.

Experts recommend paying attention to several nuances:

  1. When the standard anti-theft system is disabled, the vehicle becomes accessible to criminal thefts.
  2. The ECU system of a car engine is quite complex, so independent intervention in its programs, such as flashing microcircuits, can lead to irreversible consequences.

If you are not confident in your abilities and knowledge, experts do not advise opening and reprogramming the electronic control unit yourself, but contacting a car service center.

how to disable the APS-4 immobilizer using a red key on a VAZ 2115

How to disable the immobilizer on a VAZ-2114 with your own hands,
if this is possible, if not, then how to disable it completely. I don’t want to experiment something, I think the method of scientific poking will not help here

Look in the maintenance book. In the old ones everything was described, but in the new ones this is not the case. Ask anyone who has a car before 2003.

That’s just the point: the immobilizers don’t activate and my friends don’t have the books. But I bought it already with an active one and there is no book or anything. I found it on the Internet, but it’s too abstruse not to do it yourself, you need to reprogram something, but I still don’t understand what

I found it on the Internet, but according to normal standards, you need to reflash the system IMHO. At least for those who have APS-4, the immobilizer is turned off simply. Cut off the Blue-Red wire, only so that the tail of the wire remains from the immobilizer connector. Screw this piece of wire to the red one on the same connector. Immo will request activation. Consider the key. It will no longer bother you, regardless of the condition of the car. I've been using this scheme for two years now and no problems. But I keep the black Immo key in the glove compartment, just in case.

Almost all new cars are equipped with immobilizers. These electronic devices make it possible to prevent the theft of a vehicle by disabling the “vital” systems of the car. As soon as the attacker gets into the car, he will try to start the engine and drive away. The immobilizer will either not allow this to be done at all, or the thief will be able to drive away several hundred meters, after which the fuel supply will stop and the engine will stall.

Such immobilizers can be contact or non-contact. The former have already ceased to be produced, while the latter are very popular among car owners. However, sometimes situations arise when a car enthusiast wonders how to disable the immobilizer on a VAZ 2112 or another brand. The fact is that in the brainchild of the domestic automobile industry, problems related to electronics and various devices often occur. Let's look at the main reasons for disabling the immobilizer.

General recommendations

  • keep the contact details of your alarm installer in your car at all times, do not trust your smartphone;
  • Do not check fuses and relays in the space under the indicator panel away from your parking place or residence. This may cause the car alarm to malfunction;
  • at the first sign of a low battery in the key fob (decreased range), replace the battery;
  • if failures begin to occur when starting the engine, do not wait until the problem manifests itself completely in the most inappropriate place, immediately eliminate the cause;
  • If moisture enters the vehicle interior along the path along the left A-pillar (this often happens in the fall when leaves get into the drainage system under the hood), fix the problem immediately. Otherwise, sooner or later moisture will penetrate the car alarm head unit.

Where is the immobilizer on the VAZ-2114: photo of where it is located

How to disable the immobilizer on the Lada Kalina?

The purpose of the immobilizer is to prevent any unauthorized attempts to gain access to control the vehicle. The place where the immobilizer is located on the VAZ-2114 is located in the instrument panel, on the ignition switch side, above the engine control unit.

Location of the immobilizer on the VAZ-2114

Location of the APS-4 immobilizer on the car

The fact is that the Togliatti designers who created the “four” mocked the consumer by installing an ECU and an immobilizer under the pipes of the car’s heater system. Thus, if the tightness of the system is broken, they must be filled with antifreeze.

What is an immobilizer and why is it criticized?

Since the beginning of the 2000s, an automobile anti-theft system (APS) has been installed on all injection engines produced in Tolyatti.

Initially, the first “tens” were equipped with APS-4, but they were soon replaced by more modern APS-6.

The standard anti-theft system is otherwise called an immobilizer.

The meaning of the system is as follows: an attempt to steal a car will end in nothing. The attacker will not be able to start the engine, and if he does start it, then after driving a few hundred meters the fuel supply will stop and the engine will stall.

The idea is good, but there are a number of problems that arise during its operation:

  • Software failure. The electronics does not see the update of information supplied by the ignition key or does not recognize it. There were cases when, having stopped and turned off the engine, it was no longer possible to start it.
  • Engine blocking due to low battery. Leaving your car in a parking lot for several days in winter can accidentally activate the system.
  • Serious problems when connecting an alarm system with auto start.
  • Breakdown, short circuit of contacts due to poor location.

Interesting! The first injection VAZ-2114 were produced either without APS, or with an unconnected unit dangling inside on its own wiring. Nobody knows what this was due to (savings, lack of equipment or another reason), but the fact remains.

Troubleshooting

In the case when a car with an active immobilizer does not communicate with the computer, you need to know the following: the K-Line wire connects the diagnostic connector and the APS. Only then does the power enter the electronic control unit.

In the event of a malfunction, you need to make sure that the system is connected to the correct connector. If the result is positive, you can try to disconnect it and bridge the 9th and 18th contacts.

This will result in a direct connection between the ECU and the diagnostic connector, bypassing the anti-theft system.

In case of malfunctions related to the operation of the immobilizer, it is necessary to take into account the fact that this is a complex electronic device. Therefore, to troubleshoot it, it is recommended to contact a professional auto electrician.

Important! In the event of breakdowns associated with its operation, you need to know that restoring functioning after the intervention of incompetent hands can be difficult, and in some cases completely impossible.

Deactivation and activation (pros and cons)

The Bosch ECU on the VAZ-2114 came complete with an APS-4 immoblizer

When deciding whether to deactivate the immobilizer or not, you need to know the following. APS-6 or 4, although it has a number of significant drawbacks, it really counteracts hooligans who may decide to ride in a car parked near the entrance. The alarm does not turn off the engine and fuel system.

The anti-theft system of the 6th series, on the contrary, turns off the power to the fuel injectors (the 4th turns off the fuel pump and glow plugs). Therefore, it’s up to you to decide whether to connect it after the next glitch or not. But at least, if they decide to steal a car, then they will need their own ECU; you can’t take the car with your bare hands.

Immobilizer deactivation video

Important! When disassembling the immobilizer yourself, pay attention to the markings of its boards. The fact is that the case from APS-4 may contain a board from the 6th series. This is another, another cruel joke from AvtoVAZ

This is another, another cruel joke from AvtoVAZ.

Types of devices

Any immobilizer, not only from VAZ, has its purpose. This device must create conditions under which the movement of the car and any manipulations with it automatically become impossible if someone tries to gain unauthorized access to the car. Okay, isn't it? Someone gets into your VAZ 2114, tries to move away, but it doesn’t move and shows no signs of life at all.

This effect can be achieved using various methods: blocking the gearbox gate, blocking the fuel pump, or closing a certain valve in the pipeline, which may also cut off the air supply.

In general, you understand the essence of the immobilizer device. The great advantage of just such a device is that its electrical unit can be placed in the most unpredictable place and the thief will break his head a thousand times, but will not be able to turn it off.


Immobilizer VAZ 2114

Based on the principle of operation, there may also be various types of immobilizer devices from the VAZ plant. Some ensure complete immobility of the car when you are simply not around your 2114. In this case, the hijacker, having climbed inside, simply will not be able to do anything. Another option is when the immobilizer allows the thief to sit comfortably in the car, even drive a little, but at the most necessary moment the car simply stops rooted to the spot. An inexperienced thief may think that something is simply broken in the car and abandon his attempt to steal it. If he turns out to be experienced and understands what happened, then there will be no miracle here either - no one will look for the control unit in the middle of the street and he will have to leave.

Also very interesting are the methods of operation of such devices; they come in the following types:

  • Contact.
  • Contactless.

It is this fact that is decisive when determining the price of the device. Now let's figure out how this whole thing works. In the contact arrangement, the trigger for the car locking is the fact that they tried to start the engine with a non-original unique key or without any key at all. Of course, for the VAZ 2114 they will not make an individual key for each car, the lock simply knows certain features of the particular key model that it has and will allow it to start the engine using another one.

Another method, contactless, is much more promising. Here everything is more complicated - the car is in working condition and the immobilizer does not block any of the car systems as long as the key with its unique chip is within a few meters from the car. That is, in the car unit there is a radio receiver that records a unique code that is emitted by the chip in the key and the car seems to feel that the owner is here and is behaving completely calmly. As soon as the key leaves the signal range, the car immediately understands that it is in protected mode. So, no one will definitely steal your VAZ 2114.

How to bypass the immobilizer on a VAZ?

How can you disable the immobilizer on the Lada Priora?

If the problem is not brought to a critical state, and the car is still running, you can resort to a number of tricks.

Immobilizer connector

Domestic motorists cope with critical situations as follows:

  1. If you are a prudent driver, install an alternative immo – this is a special module for bypassing the immobilizer in a critical situation. These are two small transceiver devices connected in parallel with a protective device to the computer and ignition system. If the car is blocked by a standard system, you will have a mechanism at hand that can start the vehicle, contrary to the established prohibitions. The only negative is that you will have to fork out extra money for electric ignition.
  2. If you have lost a key and are afraid of losing the second one, take the remaining one apart. The main thing is to carefully remove the chip and not damage it, after which it can be placed on glue near the ignition. A significant disadvantage of the solution is that the car will start with any key.

If the above options do not suit you, then you will have to approach the problem with full responsibility and disable immobilizer 2114 manually.

Safety Notes

A standard device such as the APS provides the best level of protection. But an alarm system, even the most modern one, can be considered only an additional security device. It does not exchange data with the ECU and does not prevent the engine from starting. At the same time, when installing an alarm system with auto-start, blocking is always implemented. Two cords going to the main unit are connected to the starter cable. And until the security is turned off, you cannot start the engine.

Typical signaling connection diagram

All wiring connected to the ignition switch carries significant current. But doing the installation yourself does not always ensure good quality connections. In general, it is better to entrust the autostart connection to an experienced electrician. We wish you success.

Having connected a new alarm system, they often encounter one problem - the autostart does not work. You need to immediately check whether all connection points are used. In the latest VAZ models, such as 2114, the ignition switch contains three terminals: starter, power, ignition. It’s difficult to get confused here, but the engine can start and stop after 5 seconds. In reality, this is how standard protection works. How to deal with it is discussed further.

Let's assume that we are talking only about the VAZ-2114 hatchback. If the key, that is, the key fob, needs to be leaned against the platform, disconnect its two connectors (the light bulb and the antenna). And then, taking a screwdriver, you can dismantle the separate block attached to the right of the steering column:

Dismantling the APS module

The unit itself is called APS-4, but in its case, if we talk about the last years of production, APS-6 electronics may be located.

Let's say they are installing an alarm system with auto start, and a standard immobilizer, such as APS-6, has been activated. There are four solutions:

An immobilizer bypass is connected to the alarm, and a chip key is placed inside the bypass body;

You can also switch the immobilizer to service mode, but in APS-6 modules, unlike APS-4, this feature is blocked;

Finally, you can get rid of the standard protection completely, but to do this you will need to reset the EEPROM of the ECU.

A more complex, but more effective option is to reflash the control unit. To implement it, you will need a soldering iron, a computer with a flashing utility, and a board programmer. Flashing is carried out as follows:

  • First, the control module is removed from the car.
  • Next, the cover of the device is opened.
  • Now you need to find a board with immo data written on it. If your car uses the January control unit version 7.x, then the circuit designation is 24С04.
  • Next, you have two options for solving the problem - you either install a new circuit, or you will clean the old one. To perform the cleaning, you will need a computer or laptop with a Windows operating system, as well as an appropriate memory cleaning utility. There are many programs on the Internet, you can select software for a specific ECU model.
  • The next step will be to desolder the circuit using a soldering iron, as well as install a new board. Well, or you reflash the circuit, whatever. If we are talking about firmware, then with the help of a properly configured utility you can complete this task in just a few minutes.
  • When the process is completed, all you have to do is solder back the new board and check the functionality of the system.

Manipulations with the ECU controller

The VAZ-2114 controller unit may belong to the following family - January 5.1.X or ITELMA 5.1. The digital designation printed on the label in this case looks like this: 2111-1411020-71 (the numbers “72” may appear). If the last two digits are a “space” or the number “70,” it means that the BOSCH M1.5.4 controller is installed. In the latter case, erasing the EEPROM involves disassembling the block, but without soldering. And in the first case, you don’t even have to open the block cover.

Resetting EEPROM in a BOSCH controller

Let's see what the controller board looks like from below:

The 24C02 chip is the EEPROM memory. Circle the 5th and 6th taps, B and C, with a marker. These points are intended for connecting the programmer, which is assembled from three transistors.

The programmer circuit in question looks trivial. This means you can quickly assemble it with your own hands:

Programmer for EEPROM 24C02

The device is connected to the COM port of the computer. And the voltage “12 Volts” is taken from the MOLEX connector. Of course, ground must also be taken from this connector. The maximum current consumed by the ECU will in any case not exceed 0.5 A.

Now let’s look at the procedure for allowing the ECU to “forget” about the existence of the immobilizer:

The 18th and 27th contacts of the block are supplied with supply voltage (12 Volts);

The common wire, that is, ground, is connected to pin 19;

Connect contact B of the programmer to tap 5;

Connect contact C of the programmer to tap 6;

In the Combiset program interface, select the “Clear EEPROM” item, press the “Install” button;

They wait a few minutes.

The wiring of the main ECU connector looks like this:

ECU block, 55 pins

The Combiset application must be downloaded from the official website (almisoft.ru). Even the Demo version, available in the Download section, is suitable.

In the program itself, you must correctly set the number of the COM port that will be used. The COM-1 port is shown below, but this is not the only option.

Combiset program interface

How “January” controllers are “untied”

A common type of controller in VAZ-2114 cars are the following blocks: January 5.1.X and ITELMA 5.1. They need to be programmed the same way. You need to use an adapter from the COM port to K-Line, but you can easily make it yourself:

Adapter and ECU connection diagram

The homemade adapter operates at a speed of 38 Kbps. Select this value in the Flashecu program (www.nppnts.ru).

The procedure for clearing EEPROM will be as follows:

Make all connections according to the diagram;

Close the contacts of switch S1;

Wait 5 seconds;

Operate switch S2;

In the program interface, click the “Clear EEPROM” button.

The ECU connector diagram is shown in the previous chapter. It is the same for all VAZ ECUs equipped with 55 terminals. The program interface, in turn, looks like this:

Screenshot of the Flashecu program window

The erasing procedure takes several minutes.

General advice for everyone

The block itself, which was mentioned above and which needs to be “untied” from the immobilizer, is always located in one place - under the tunnel cover on the right:

Interior of the fourteenth model

Of course, we are talking about the 2114 family, and in other VAZ cars the unit will be more difficult to find. Installation and disconnection can be done as follows:

Remove the negative terminal from the battery;

Unscrew the fixing bolt and remove the clamp together with the block;

During installation, the steps are carried out in reverse order. But there is one trick.

After connecting the ECU, power is supplied to the network. And then, oddly enough, you need to turn on the ignition and wait for the Check lamp to come on. And only then, turning off the ignition, can you continue operation.

Note that the immobilizer itself, after flashing the unit, should not even come into contact with the latter. Therefore, having disconnected its terminal block from the immobilizer, they carry out the standard modification:

The wires are cut off from terminals 9 and 18;

The resulting branches coming from the loop side are connected.

You don’t have to change anything, but simply disconnect the connector completely, losing some features:

PTF rear headlight control;

As you can see, the immobilizer in modern VAZ cars has many functions. And they turn it off for one purpose - to activate the alarm system with auto start.

Double-row connector for standard immobilizer

The immobilizer bypass module in any VAZ car works well in one case - when it is connected to a break in the antenna circuit. But not all factory-produced modules are designed for this connection option in principle.

Possible problems

On a VAZ-2114, the immobilizer can sometimes block the operation of the internal combustion engine for no apparent reason, so that it cannot even be started again. This is due to the design feature of the system, which, based on the main key code, gives the command to start the internal combustion engine.

Problems with starting the internal combustion engine begin when the anti-theft system stops accepting the code. In this case, the operation of the vehicle’s engine is blocked by the engine control unit.

To eliminate the problem of the anti-theft system, use diagnostic stands, a laptop or a personal computer.

There have been cases where the anti-theft device malfunctioned due to signals from electromagnetic fields, incl. and from interference with a mobile phone.

Functions and purpose

Domestic manufacturers of the VAZ-2114, addressing the issue of protecting the car from theft, equipped the base model with a fuel-injected internal combustion engine with an anti-theft system - an immobilizer. This is an anti-theft device with a special program that both promotes engine starting and blocks its operation.

The device sends an electrical signal to the engine electronic control unit (ECU), which in turn gives the command to start the internal combustion engine. Thus, the anti-theft system works to block the internal combustion engine in the event of a car theft.

The principle of operation of the anti-theft device is to break the electrical circuit of the vehicle, which serves to start the internal combustion engine. There may be a break in one of the electrical circuits of the ignition or starter system, which makes starting the engine and its operation impossible. Therefore, in the event of a vehicle theft, the anti-theft system will resist the thief, blocking the engine from starting.

Problem Resolution

What to do if the immobilizer blocked the engine from starting? First of all, make sure that it itself is functioning normally - the indicator on the dashboard (if there is one) indicates that the chip code is not recognized. If the indicator “shows no signs of life” when you turn on the ignition, then you should probably start by checking the electrical system - perhaps the fuse has blown in the section of the circuit where the immobilizer unit is powered.

Re-register a key that is not recognized by the system - this solves the problem. However, there are two ways to program the immobilizer. In the first case, which is used on most foreign cars, programming of key codes is carried out by a dealer diagnostic scanner, via an internal network (the request goes to the manufacturer’s servers). The entire set of keys is registered at one time, since at the beginning of the training procedure, data on previously registered keys is erased from memory. So the owner himself cannot do anything with the immobilizer: he turns to the official dealer of his brand or to a company specializing in such work. As a matter of fact, the existence of universal devices for training immobilizers “plays into the hands” of car thieves. And you should approach the choice of a company offering immobilizer training services more carefully - the car owner will not control how many keys are actually registered, and there may be an “extra” one for the future.

The second method of training the immobilizer involves the presence of a master key in the kit, which is used to program the others. This allows the owner to perform immobilizer training himself, but only if the master key itself is recognized. For example, the APS-6 unit, which is very familiar to VAZ owners starting with Kalina, has a similar learning mechanism.

You will also be interested in:

To program “working” keys using a training key on the APS-6 unit, you need to:

  1. After closing the doors, turn on the ignition with the learning key.
  2. Wait at least 6 seconds, then turn off the ignition. The immobilizer indicator will blink rapidly, indicating the start of the learning procedure.
  3. Insert the registered key into the lock and turn on the ignition. Do this before the immobilizer light goes off. The buzzer will beep three times, indicating that the chip in the key has been recognized and read. If the indicator goes off and there are no beeps, this means either that the ignition is turned on too late (repeat step 1 onwards) or that the immobilizer is faulty.
  4. Wait until two more beeps sound. This confirms that the key code is stored in the controller's memory.
  5. Repeat steps 3 and 4 for the remaining keys.
  6. After turning off the ignition with the last key you registered, with a pause of no more than 6 seconds, you need to reinsert the training key into the lock and turn on the ignition. First, three beeps will sound, then two more.
  7. Turn off the ignition, but do not remove the key from the lock until you hear a single signal. The blinking frequency of the immobilizer indicator increases. If not, go back to step 1 and try again. A secondary error will clearly indicate that training with this master key is impossible. Therefore, contact the service.
  8. When a single signal is heard, you need to quickly turn on the ignition. The buzzer will sound three times and the immobilizer indicator will go off. After 2-3 seconds, turn off the ignition. The car will respond by flashing the hazard lights and beeping.
  9. Remove the learning key. Before checking the operation of the registered key, wait at least 10 seconds.

The procedure looks complicated, but it ensures that the user cannot accidentally trigger relearning by simply using the master key to turn on the ignition.

In some systems without a master key, the manufacturer provides emergency PIN codes for key programming. On old Renaults, the PIN code is calculated through the Trantir program using the code printed inside the key body; on Kia/Hyundais up to 2007, it is determined by the last digits of the VIN, even without special programs (online services), and so on. The code entry itself is performed both by standard means of the car (Renault has an interior door lock button) and through the diagnostic connector. In this case, you will have to buy an adapter for old cars with inexpensive devices like VAG K-Line from Aliexpress. You can find the necessary software on the Internet. The already mentioned Kia/Hyundai uses the Cascade program, in which the immobilizer learning process is interactive and placed in the corresponding menu item.

We disable the immobilizer on the VAZ-2114 with our own hands

To disable the VAZ 2114 immobilizer, you must adhere to a number of rules:

  • Before turning off the system, remove the protection connector;
  • You need to be extremely careful so that the system does not recognize the shutdown as unauthorized access.


Immobilizer location option

There are two algorithms for dismantling the device from the machine. 1. Trimming contacts:

  • we find the control unit next to the radio or where you hid it;
  • remove the connector from the block and find the ninth and eighteenth contacts (there are 20 in total);
  • we cut the contacts, insulate the ends and dismantle the immobilizer;
  • place a jumper between the ECU and the diagnostic block, which will restore the K-line connection;
  • connect the cut wires and return the connector to its place.


Disabling the immobilizer

2. Manual flashing:

  • We take a computer, a software package, a soldering iron and a programmer;
  • disassemble the ECU and connect the programmer to the controller;
  • read the BIN firmware file and information from the EEPROM and save the information in a safe place;
  • install a clean, pre-downloaded EEPROM;
  • We assemble the device, if the ROM was sealed, you will need a soldering iron, if not, you are lucky and everything will be faster. As an alternative to a soldering iron, you can use COMBISET; it automatically clears the EEPROM, leaving clean factory firmware.
