Hello, today we tried to remove lambda from my friend car VW BORA 2.0 115hp AZH 2001, car is from USA i think. I used Kess v2 and we read it with 38family protocol. When i tried to read it shown that unknown ecu i still procceded risking to brick, but after reading it shown checksum error, and then unrecoverable error. We still continued, modified file with lambda remover and do not modified checksum with any other software, because winols not recognised it. After flasheing new file it not started, after trying recovering and puting file we firstly read nothing changed. SO meybe someone could help how to recover, in boot mode? And meybe someone could put original file it may help? I put my all files, log file and ID. Or meybe it is enaugh to correct cheksum?
