I'm opening a new topic for my problem cause i don't want to mess someone other's topic.
For a week now i am trying to make my car to work again after a failed (due to checksums) write to the ecu. Today nefmoto' s utility failed to flash the ecu and when i tried again it couldn't even connect. I tried vagcom, galleto nothing happens. I can't even connect and read the ecu data. I think the ecu is gone to heaven. I removed it from the car now, and i will try to bench-flash it to see what will happen. Does anyone here have any idea what else can i try to recover it if possible? I would appreciate any help. Thank you, and sorry for my english.

I would use your Galletto in boot mode for you best option to recover your ecu .Hopefully it is just a software issue ,start with flashing an original .bin you know to be good .
Good Luck!

If nothing works you have to solder  |

I think too with galetto is the best way with boot mode but maybe if you tell us what ecu do you have, part number or with more information ,we could help you more.

The ecu is a bosch motronic 06A 906 032 MJ used on a VW golf IV 1.8t.
I found an original file for the ecu and i think i succesfully flashed this file on the ecu via galletto in boot mode. I will test it in the afternoon if i have time or tommorow. Thank you all for the answers.

I am having a lot of troubles flashing in car but it always works 100% reliably on the bench. I am experimenting with fuses now as I think that depriving ECU of voltage on terminals not used for flashing is the way to go and the ECU might be getting too busy with heating up O2 sensors and such and hence failing flashing in the car. So far I flashed ok last two times after removing largest 30A fuse for ECU so I think I hit the jackpot here. Before that I would fail 4 out of 5 or even more flashes, it is this bad in my Allroad. Since I already bricked my ECU about 10 times to date (including one instance where whole 1MB was wiped out completely) and each and every time eventually recovered with Galletto boot mode, I can authoritatively stated that there is no way to completely screw up the ECU where you would need flash programmer to recover. |

Why not use a KWP2000 with ME7 edition software ? flasing via obd shoud be doable. Or just get a MPPS. That works brilliantly.

Do you happen to have a log file from the NefMoto flashing software that shows what went wrong? Boot mode with Galletto is the cheapest and easiest option to recover an ECU that doesn't respond after an OBD flash. |

@Tony i will check for the log file. @Fotis what to desolder the eeprom the flash? and if i must rewrite the flash all ok. If i have to rewrite the eeprom where can i find an original file?I didn't have the time to test the ecu i will post the results. Thank you all.

Something to keep in mind, if the ECU has a stored error code for invalid checksums, then the only way to remove that error code is to erase the eeprom in a programmer after desoldering it, or to flash and disconnect afterwards with the NefMoto flasher.
The invalid checksum error codes are only cleaned when disconnecting after a successful flash over OBD. Flashing with Galletto or any other boot mode tool will not trigger the ECU to clear the invalid checksum error code.

Galletto is more than software, it's also a cable. There are several posts here about it that go into detail about it.
