Can't downgrade BIOS from 1.35 to 1.28, 1.24 or 1.04. Any attempt to flash BIOS to version lower then 1.35 has BootBlock Emergency Recovery Mode screen. I take BIOS ROMs from HP site, and i don't understand, why this ROMs is corrupted? Do you have ideas, how to downgrade BIOS version without using CH341A, because i'm afraid, if i desolder EEPROM one more time, contact pads will break?
