Hi there!
Yesterday I made a full flash in boot mode. Everything was fine until I wanted to start the car. I flashed the ECU with an EWS off software, but the car didn’t start. I read the fault codes with INPA. It throwed various error codes like “0, 100”. What’s the problem? Has anyone ever encountered this problem?

Error code 100 means that the ecu self test has failed, in almost all cases the self test fails because the checksums where not corrected in the binary that was flashed to the car. If the self test has failed the car will not be able to start. To fix it you need to correct the checksum in your binary and flash it again to the ecu.

In the EWS off software EWS communication error 128 is changed to error code 0, it doesn't cause any problems but if you want to get rid of it you can set c_abc_inc_tout_imob to 0.

Galetto doesn't correct checksums. mss5x flash tool does. But if there is checksum error codes after full flash, only thing that can save the ecu is know good full flash with jmgarage flasher in bootmode.
