This chip is fully erasable by any tool. You just had no luck
Your options are:
a) Clean the chip well and try erase again with R270( worked few times for me)
b) Read chip ID from old chip one and use emulator (MRPPAD, Smok)
c) Buy used cluster then virgin and code it with Esys.

Hello.....

Can you explain in detail how to program/code with ESYS?

I have now a case that need INCREASE  mileage (F12)  and another one to DECREASE (F10)
Both have 35160D0WT   
MRPPAD  (MDP) can read/write ID data.
If I replace eeprom to INCREASE the mileage, writing back the original ID data + modified EEPROM data...  will work OK ?

Thanks!
