	Seems like I bricked 95160 « on: December 06, 2021, 02:18:16 PM »

Hi All,

I think I bricked a 95160 trying to write it with a clip without desoldering. Yes, lazy...

I have since tried reading it with an adapter and by soldering to adapter directly in zif socket. Using a vvdi prog. I pulled a ST 93C86 out of an MS43 and was able to read and write and read that just fine. Therefore, I believe my vvdi prog is operational.

Will this 95160 chip work properly?

So I got M95160-DRMN3TP/K from digikey.

I am able to read it and write a blank bin but it anytime I try to write a non blank bin I get 'Write Error(00)'. Does anyone know if perhaps these are write protected or something? I suspect my VVDI Prog should be able to write any ST 95160 not just the exact ones that came in the ECU's?

TIA

If I do a verify, I get a 'check failure'. Perhaps the checksum is different for these two chips? In over my head here, anyway to correct it to make it work?
