Clevo P775TM1-G AMI BIOS recovery

Hello,

I'm trying to enter recovery mode on a bricked Clevo P775TM1-G.

Pressing Fn+B during POST does make it read from the USB drive but after a few seconds (USB drive with LED blinks for about 3 seconds) it just gives up and does nothing, no matter how long I leave it.

Reading from the USB drive occurs only after the keyboard lights have finished their show(seriously, whoever programmed this had a lot of time on his hands).


It does seem to recognize AMIBOOT.ROM and BIOS.ROM files because if the filename changes, then the LED on the USB drive only blinks for 1 second before giving up.

I've tried with all BIOS versions I could, olded to newest, but what I would really want is 1.05.09 as this is the last known version to work properly.

BIOS chip is MX25L6473F . BIOS is AMI Aptio if I remember correctly but BIOS files are from manufacturer so it shouldn't matter.


CH341A programmer is on its way but I was hoping to do something in the meantime.

I've attached a service manual, maybe it helps. Page 75.

I'm at the end of my knowledge. I hope someone could please help with this.

Thank you
