So I picked up a Toshiba laptop, and was going to modify it. Toshiba Satellite C850, model PSCBWC-05700J
I've done tons of hardware upgrades and Windows reinstalls, so I thought it would be easy as all the others I've done.
Wanted to upgrade from a Celeron B830 to a Core i3 2370M, but apparently Toshiba has something in the BIOS that shuts down the computer after 1/2 hour of runtime with a processor that is not approved, even if the socket/chipset/wattage/voltage is all same/same. (read this on several forums)
SO, I downloaded a modded BIOS that apparently unlocks two hidden screens, hoping that there might be some options in there for processor support.
I haven't got the new processor yet, I was just wanting to unlock those additional BIOS screens now, and have a look in them to see what options there were.
The Celeron B830 is still installed and was working fine.
Ran the modded BIOS, ANNND, now it's bricked.![Angry]( "Angry")
The standard BIOS download from Toshiba is an .exe file, and must be run from within Windows. Grrrr.
Here is the Toshiba downloads page for my specific laptop.

the correct BIOS for my unit is listed under the DRIVERS tab.
It uses the InsydeBIOS v6.80, which was installed and working great before the bricking.
Apparently, one can recover InsydeBIOS via USB stick and fancy keystrokes, so.....
I tried looking for ways to extract the BIOS files from the .exe, and I used a universal extractor program, got the .FD files out, tried loading them to a USB stick, and powered on the laptop while pressing the windows key and B.
nothing. nada. Tried renaming the .FD files various things as suggested elsewhere, BIOS.FD, [model].FD, and on and on. No joy.
This is my first experience with a bad BIOS flash, and I'm completely lost.
Can anyone help???
Please?
If I can just get it working again, I'll scrap the idea of the CPU upgrade and just use it as-is.
