I now just tried with the PICkit3 to:
1. Read a good PIC firmware from a good hash board
2. Write a good PIC firmware to a dead hash board
No effect. The dead hash board is still dead.
So it is probably not just "soft bricked".
So I wait for the answer from BitmainWarranty (
www.bitmainwarranty.com).
I have previous experience with the PICkit3.
Do you have the image file from the good hash board? I'd like to have a look at it if you could send it to me.
In what way is your board dead? Mine died immediately AFTER a firmware update, it never hashed on the new firmware, so I'm pretty sure it's software related, unless the bad software caused something to overheat.
Bitmain thinks it's an incompatible firmware, which is weird because they said it was for "all" but we'll see if they can help me. They responded to my first e-mail and I gave them more information, now I'm waiting to hear back. Thankfully I only flashed one of my S9's, the rest will probably never get a firmware update, it's too risky.
