Title: RSA Signature error
Post by: KasperH on August 26, 2016, 04:07:21 AM
Hello Nefmoto cummunity :)

i tried flashing a self modified bin file yesterday.
The car started and ran fine first time but wouldnt turn over and i had to boot mode flash a stock file to get it to run again.
i checksummed the file with mtx and me7check before flashing and there were 0 checksum errors but a rsa signature error,
and i suspect rsa error to "brick" the ecu.

is there any way to fix the rsa error or disable rsa checking?

thanks in advance.

mtx plugin is old news and doesn't correct RSA.   Use me7sum and profit.

i made a spelling mistake, i used me7sum, not me7check :)

It is not possible that you used ME7Sum to *correct* and ended up with a rsa error.

Did you use NLS/LC patcher on your binary?
If yes, that is the reason for the RSA error.

Either turn RSA off or implement NLS/LC so that it does not overwrite memory regions responsible for RSA calculation.
