help kess v2 marelli 6f3 block

[isfedales82]

But i'm trying to figure out why my kess v2 blocks marelli 6f3 gpunto 75 cv
After I write the file, it says the writing is done correctly, Turning the picture I do not feel pump activate, I try to write insect code with the kess ... but after no longer the ID....
I recover the ecu with ktag, immo off partial, and fix flash on small part
everything works



I try to write flash with kess until the token ends, but once it just does not block .... is it a cecksum error that makes the tool?


Are the hardware components the problem? I would not change for anything


Some help to fix it, it's scary to use it like that

thank you

Can not you tell me any advice? If I can fix it by doing hardware reworks or need more thanks

No one can fix the problem, the tool fails the checksum
