Hello
I can't properly erase BIOS chip MX25U12873F.
I can read it and write it, but before correct write, it have to been erased, but when I click erase program shows success, but when I try do blank verification I have message "chip disconnected".
I use CH341A programmer with 1.8V adapter and clips.
When I try read or write it takes 3~5 minutes and "run" LED on programmer is blinking. When I try erase, it takes up to 15 seconds, but "run" LED isn't blinking and after that, chip isn't erased correctly.
I also tried to unprotect that chip but software show's it's already unprotected. I tried solutions from that website https://khandishnetwork.com/2021/01/...rror-solution/
My motherboard is GA-AX370-Gaming 5. That motherboard have dual BIOS, but both are corrupted.
