I’m searching to flash the A14 update on my device, but the FD file has an expired signature and the manufacturer no longer supports the machine.
I’ve already tried different ways, including here on the forum the method Insyde H2O bios unlocking/flashing also without success, thank you to anyone Can you share the solution!
is the laptop bricked ? i think we need more details to help.
do you have an external SPI programmer (CH341A) ?
i see “QCL01A14.fd” in 7520A14.exe
