	fully bricked me7.5 ecu « on: April 08, 2024, 09:49:06 AM »

hello
i accidentally fully bricked my me7.5
edited the original program and forget the checksum corrector
now the car won't start and I can't read and write the ecu
I tried boot mode but it also didn't work
my apps ran out of 10 use
i have kess v2 (china) and galetto 1260
any ideas to save. this ecu?

Unplug possitive battery for 2 minutes. You can start car after that, flash tune also

I tried boot mode in my desk, in the car, unplug the battery, boot pin 1 sec 5sec 10sec
And still no response
Galetto: boot mode inactive
Kess v2: unknown ecu type and wake up error

Don't put power to pin 121 when you try boot mode
