Acer Aspire 7740 BIOS Brick

[JonnieChimpo]

I hope this is in the right thread. Either way, thanks to anyone for suggestions.

I successfully bricked my friend's Acer Aspire 7740-5691 while upgrading the BIOS from 1.15 to 1.16 in Windows. Yes, I am an idiot. The computer rebooted with no screen. The CD-ROM and the fan spin up but that is all. I am sure you know the drill.

What I have tried
I have been all over the internet and even found the service manual

I have created a CRISIS disk on three different USB sticks (16mb, 2gb, 4gb). The files are there and I tried multiple versions of phflash16.exe and multiple versions of the BIOS.

According to directions everywhere, I am supposed to hold Fn+Esc while hitting the power button. I have tried this with the battery in, with the battery out, with the CD-Drive and hard drive out, and in. The problem is that the computer never starts reading the USB drive. It lights up for a second when power hits it but that is all. It never seems that the emergency flash even starts. I have tried every other key combo I have found out there.

Is it possible the Boot Block was overwritten and I am totally up the creek?

The Acer files are here. I really appreciate any advice.

1.15

1.16

1.27

You should try the PHLASH16.EXE that comes with your original BIOS , its found in the DOS folder in your original BIOS .
try with different keys combinations like fn+B and others .
