Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).

The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6... -

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -
