The BIOS failed during the update. I recorded a dump before attempting to flash it with CH341A, but it appears to be faulty. After flashing and checking the comparisons, no errors were detected. After soldering the chip into the laptop and attempting to boot it, I saw a logo for about 10 seconds and then it shuts down. I flashed it with NeoProgrammer V2.2.0.10. After 15 attempts, the BIOS chip stopped being detected completely, and SB 2 started turning off after 1 second at the logo. After unsoldering the flashed chip and comparing it with the dump I flashed, they failed to compare. Could it be that the chip itself is write-protected, or do I need to change the registers when flashing? Only QE=1 was enabled. I’ll post my dump and the latest one I found and tried flashing… I forgot, the BIOS from SB2 13.5 forced the cooling to run at maximum and also shut down on the logo… Waiting for new chips.
