med17.5.21 stuck in boot mode

[patrykv98]

Hi DK!
I have a damaged ecu med17.5.21 when writing mod file via bench with pcm flash module 71 (bench mode).

I have full backup (flash, eeprom and password) which was made before the ecu was damged.

Now I'm trying to upload flash and eeprom in module 53 (boot mode). Writing is successful but ecu does not exit boot mode. Ecu is stuck in boot mode. I can read and write it without connecting boot pins.

The Ecu was definitely not damaged when opening it, because it had already been opened before.

When I read what I wrote in boot mode, I noticed that the file I was reading had a missing part compared to the backup flash. I think pcm flash skips some area in flash when writing and ecu stays in boot mode.

Has anyone had a similar problem?

Ktm or pcm ?
If ktm try with ktag write mpc and epr boot mode (buckup)
If you have pcm contact oleg

I have KTM.
I tried with ktag but it doesn't identify ecu. My Ktag is poor clone it is not reworked. Maybe that's why it doesn't worked.

For me it is not necessary to restore this ecu, because i have it for test and experiments.

But I would like to know why I cannot fix it

I have a same problem. Edc17c60 i trayed with ktag origine and autotuner no chance.
You need buckup'pass and original pcm flasher with 1.2.1 for fix (module 53)
