Good evening gents,

new day - new challenges (new ~~~~ up ;)


Today I was playing around with the updated Kess v2 and wanted to write an ori file back to an EDC16 on a BXE Skoda Octavia when above message appeared on the screen.

I have tried Writing and also Recovery without success - this message comes up on Kess.

Any idea how to overcome this?

This is a kind of bumpy ride as I've already ~~~~ed up my KTag ;)
Also I've done the read out via OBD so I haven't got a full backup. Am I right thinking that?

Now no choice obd work, need open ecu and work directly on it on bench to get it recovered. :(

Well, depends how you look at it - I AM having serious fun :)

BTW, you right no pro would do that :D
This is a non runner from my mate's junkyard - had a problem not receiving a proper signal from the camshaft sensor so they dumped it and I had no better idea but play around :withstupid: So it's not really an issue, more of a challenge.

Could have I done a full backup by OBD anyway with Kess?
Also I reckon for immo off I need different tools, don't I?

That's fine. But would it be possible to do anything to recover the ECU (apart from immo off first) if I have only read it initially via OBD.
As that's not a FULL backup, is it?

not really mate, part read or full its normally just flash, kess,
eeprom needs to be read bdm or removed and read, willem i think
yes would be immo off i think all you can do

but immo off is another tool, I reckon

EDIT: And a different subforum ;)

No mate its eeprom, which you can write over bdm nothing special required, and immo yes another sub forum on DK, but many guys on this part capable of immo off solution, no biggy

Bad hardware, need rework your kess pcb with proper components.
