T43 reflash fail

[dzidaV8]

Hi!
I got back to that C6 yesterday and was able to read ECM and TCM using HPtuners and extracted binary but haven't analyzed it yet. Do you see anything out of ordinary here?

boot block have some block data written on empty space. It could be bad flash that got out of hand or file could be good and hp might on purpose add the data to file.

If you still have hpt cable you can do external log of reading to confirm the origin.

data from 35fa0 -37f01 is copied to 2809e-29fff in bricked file. IN good stock boot block this area[2809e-29fff] is FFs

otherwise file is good, checksums match. If this is hpt bricking the file, a new tcm will be needed. They are not very reliable anyway.

Is there a way to modify the binary in the .hpt file to try and flash it back?

You can try to, but hpt will not likely flash the bootblock, even you fix it.

The scramble might be related to hpt extraction and the actual bin file in tcm might be good.

I can try to send you some script to dump tcm, but it will take some time.
