Flex Unlock BMW MD1CS003 ECU Successfully

Magic Motorsport Flex unlock BMW Bosch MD1CS003 ECU successfully.

Unlock in glitch mode.

Remove the resistor. Resistor was fitted back afterwards. The resistor value is 0.1ohm.

Then read and write on bench.
Car start perfectly.

Some also suggest do not remove the resistor from the board, just fold it to the side and leave it soldered with one contact wait for the mainboard to cool down.

If not read is a resistor damage. The resistor was poorly soldered. Check if you can communicate in bench mode. If you can't, connect using the boot glitch method but select the bench connection in the software. If you get communication then, it means you definitely have a resistor issue.

If car not start, here is the customer solution:

Write full backup
Than start the car .
Read the flash .
And than mod file
Start the car again
Clear value.

Clear DTC.

After being unlocked by Flex, is it possible to read and write with another tool?

One of Flex users has tried on a Bosch md1cs003 ecu! Before unlock ecu, on kess v3, fgtech, and flex, ecu can’t be readed and you have classic message that ecu is under developmend and you have no id; after unlock, on kess3 and fgtech ecu is recognized and he has also chip id but after some attemp read failed with error, on flex of course can be readed and writted.

Instead ecu unlocked by fgtech can be read and written only with fgtech with their new protocol; flex and kess3 have classic message that ecu is under development. So, if is unlocked by flex you can use only flex, if ecu is unlocked by fgtech you can use only fgtech. Same as autotuner.
