RE: FG Tech BMW e39 540i
BMWs sensitive to voltage, but the error message you had was checksum not supported right? not voltage related

looks like this is ME7.2? there is boot mode option for it, luckily for you as the other 2 ECUs there isnt

it seems you connect like this:

then ground boot pin

if you have no comms then you may aswell remove ECU, open it and atleast show us the hardware configuration


PS - files are not corrupt, you had a bad flash
