Hello,
I have a Lenovo Legion S7 15ACH6 that was interrupted during a BIOS update and is now bricked. Symptoms: fans spin, RGB keyboard lights up, but no display/POST.
The BIOS chip is a Gigadevice GD25LR128. I’m using a CH341A with a 1.8 V adapter. In AsProgrammer I selected GD25Q128 (since GD25LR128 isn’t listed) and successfully made a dump (BiosDump2_pf3eg12j.rar).
My understanding is that I’ll need a known good BIOS dump for this exact model, ideally matched to my laptop’s serial number (PF3EG12J), and that the Windows license key/serial should also be preserved.
Can anyone guide me through the proper process of rebuilding or flashing the BIOS for this machine?
Thanks in advance!
