BMW E39 No Communication after writing

by **kaan1208** » Mon Jan 20, 2020 6:36 pm

Hey.

i wrote an original file with KTAG in EXTFLASH. Now the ECU is not communicating. I tink i need to virginize the ORIG file.
Anyone here who can do it for me or IMMO OFF?

do you have any read before writing?

Jup, but its absolutely bullshit - wrong read. not possible to write it in the ecu.
I think the easiest way is to virginize Immo or delete immo?

Your problem is not immo but corrupt flash, best thing to do now is bdm read, and hopefully someone has matching bdm reaad

I did a full read with ktag boot mode. Is it enough? Because with ktag is bdm not possible

For IMMO block ECU to be alive. Seems your file corrupted - hope you not used china KTAG. You may need ORI from someone as your file corrupted and try push it to ecu.
