I have ecu board#1981 here, the customer took it apart, left one clamping plate loose, probably touched across some contacts inside as a result.

The problem is, the ecu is stuck in bootloader mode.

I can upload firmware (1.0.73), remove power, and on the first power-up it is back in bootloader mode again.

One reason to remain in bootloader mode is serial loopback on the ECU RS232 lines (TX to RX). It need not be a direct "galvanic" path or short. We've seen capacitive coupling in one case, when a (in that case 2m long serial extension) cable without anything connected to the end caused loopback mode. With notebook connected this is unlikely to happen though.

MT says wrong firmware expected, vemstune says stuck in bootloader.

I also tried to add "tools\megaloader.exe firmware\upload.hex -wE 38400 -c com1" to the "upload-firmware 16x16" file.

And I tried PSItuner, which worked for me in the past. But nothing will work this time.
