Hello guys,

Need help from you.

Today i read EDC16C31 using Kess clone.

I read iD and read file without any problem.

deleted EGR and tried to write new file.

in a middle of writting i got an error. suggested to do a recovery.

Ok i tried to recover it, but it couldnt wake up.

So i tried to write original file back, and i got unable to prepare rolling code error.

Anyone could help me out ? :)

I am sorry to say this, but you can only recover this ecu with BDM.
But, you need flip PCB, be carefully if you do this job to not brick PCB!!!
