(Solved) Kess v2 error “External exception EEFFACE

I replaced chip and reset tokens, then get connection error “External exception EEFFACE” as following picture shows.

Try follow steps:

1.If you connect to internet with this clone tool,or make online update .The interface is destroy/broken

1.–Buy a new NPX chip with 60 tokens inside. Desolder the old NPX and change it with new.It cost 14-20USD, some users call this chip as CPU Repair Chip, available at: https://www.chinaobd2.com/wholesale/kess-v2-cpu-repair-chip.html . Note: NPX is out of stock in some sites now, because the newest KESS V2 need not replace NPX, the NPX is preinstalled in the machine .

2.–or you have to weld a connector on backside of interface ,and plug the J-link programmer.
You can reset the Kess v2 to virgin. CHINAOBD2.COM is available with J-link V8, cost about 20USD, user can buy at:
