Hi guys, have an NBT (not evo) to play around with that has been bricked by BMW dealer

Thanks for the reply,
Yes i know its Qnx, I have it open in putty, im wondering can the files be imported via USB or does it have to be over tftpd
Why do you need ssh if connected over serial?

Someone suggested earlier in comments, to see how Audi MMI is repaired in almost the same way, so may be this is a starting point for you to better understand.
