I have decrypted file from dash by obd, damaged eprom by obd now dash is dead, need correct crypted file for this dash, I try some crypted dumps but not work. Thanks for help.

Decrypt file write via OBD.
Crypt file need to write direct with programer.

Since you said you have other crypt file , try writing with programer direct on chip.

Write it via obd and not work, and write other crypted files with programer, not work too. But it was working dashboard before file damage

I looked your file and it does not look damage, It is possible that you damage something else in Cluster.

Try all crypted dumps you can find by dash number, if you lucky and crypto code will be the same as nec procesor your dash will work. But you must to make backup 93c86.
