FG Tech BMW e39 540i
Hi guys,
I was trying to chip my e39. I got a file from a German website. I have Galletto 4 and FG Tech for flashing ECU. However when was writing a modified file I got a message that "Checksum is not supported". At that point I didn't now that I shouldn't have kept on writing it on. I messed up and bricked my ECU. I've sent original and modified files for checksum correction and I got corrected file back. I've tried flash the ecu with my new file but I'm getting same error that checksum is not supported. Is there any way I can upload old original file or modified one somehow? Is there any other software which would work with galletto 4 (clone) properly ? Any help would be appreciate ! Thank You ! |

You should be able to write the original file back as that should has checksum corrected
forget the modified file at this stage you are lucky you still have comms to ecu at all |

Which DME is it? M5.2, M5.2.1, ME7.2? There are boot mode methods for some of those.
You probably flashed a different software version partial file. You might be able to recover with BMW tools like WinKFP. |

I sent it to tune guy and I got a modified file back. I was able to carry on a first flash with checksum not supported but when I was trying to flash again with my original file I couldn’t do it. Message send file to fg tech was popping on and it didn’t even start doing anything. It’s me7.2 I believe. I do have icon next and connected to ista p but it want me to adjust values for injector so I didn’t reprogrammed. Never done it before. Sent from my iPhone using Tapatalk |

RE: FG Tech BMW e39 540i
I have upload 3 files , original, tuned and checksum ok. Each one is 64KB. I was wondering if they are corrupted or something. I have previous experience flashing my 525d files were around 1024KB.
Is there any chance someone can have a look at those please ? |
