I attempted the flash and got up to 5 seconds left. File was validated then went to 0x05 bad file. And failed to write section error: 7F 36 22 please help.

Plugged in volts reading at 14.7
I8a0s Kline

2007 n54.

Used BT cable and BMS flash. attempted to force full write both the bb flash and my stock ECU file. No lucky same two codes of 0x05 bad file and the 7F3622 code

Keep trying to force a full write. kLines are really picky. It took me multiple times to write.

I'm at 2 hours of force writing. Constant 0x05 bad file even on my stock ECU map.

Try a different (older) laptop.

My surface pro used to work perfectly and then one day bam, nothing but issues.
I took an old netbook, loaded a fresh copy of XP, installed only flashing software and now I can write successfully 9 times out of 10 now.

I'm personally getting tired of flashing via *********** app. Prob start looking into cobb here soon.
