Recover Corrupted BIOS
Posted on 2013-11-10
Can anyone help me with an Acer Aspire 7720z laptop?
I did a BIOS upgrade and the laptop HUNG, so, I remove power and battery after many hours.
Now the laptop does not start because of the corrupted BIOS.
Now is there a kind of backdoor to recover the BIOS, but that's asking for a USB Floppy drive.
I used 'Crysis_Disk' to create an USB stick. I renamed the acer BIOS file of my machine to BIOS.WPH.
I put in the USB stick, removed battery and power cord. While holding the Fn and the ESC key in, I plugged in the power cord and pushed the power button.
Only nothing happened, I would expect the power button would be blinking, I tried on every USB port without success.
I also tried this with many USB sticks (size. 250Mb, 2 GB and 4GB) results in the same.
I also tried to change the BIOS filename to the original one but no result.
