Toshiba Satellite L850-1L8 BIOS bricked, need key recovery flash startup combination
#1
Hi,

So I was building a hackintosh of my Toshiba Satellite L850. Noticed I needed to change something in the bios so I downloaded Donovans (on this forum) really nice and well unlocked bios mod of the newest available bios version which is 6.80.  Big Grin Big Grin Big Grin

Bios is: InsydeH2O rev 3.7

Cause
I got stingy and went in the modded well flashed bios a couple of days later and tweaked the system a bit further. This time I decided to turn of some unharmfull options (VT-d, etc) but also to turn on internal graphics card and this is where I messed up. I should've Googled first if that was a wise thing because will doing that I also max'd the maximum dedicated RAM for the internal graphics card (1024 MB) and now the system does not boot. No screen, no normal fan speed, 1 LED on, the fan speed in some kind of extremely low survival mode and restarting after a couple of minutes and continues this process. No beep sounds, no screen on, not even a sightliest sign or response that it's still knowing what the machine itself is doing. 

Recovery Attempts
  1. - Bios jumper (jrst2501) reset without succes 
  2. - Connecting external screen without succes
  3. - Used Andy Bios recovery tool to get the recovery filename. It came back that I had to rename it to FX64.f? That seemed odd with that questionmark as a file extension name (had to use Linux to change the filename with a questionmark as extention). However I tried both ways. Copied the single .fd/.f? file to a FAT formatted USB. Tried to flash it with FN + B and a couple of other combinations like FN + ESC. Even tried Windowskey + ESC. Nothing worked, no responses. Tried the same with the recovery filename as FX64.fd. without succes
Tried all these recovery options with the battery taken out, charger taken out, SSD, Memory taken out, CMD taken out and mixed it up all kinds of ways to see if it would do something different but nothing changed.  Not a single flash on the USB that gives me the sign of being atleast touched seen or known it's plugged in.

I don't know what I am doing wrong. Either I have the wrong key combinations to flash, or the machine is really fully bricked. 

Been Googling for days now and it seems that almost everyone can escape this problem once ended up with but only the Toshiba's of the L850 series same to be impossible or atleast, no one has manage to rescue their machine. I could buy a new PLC on AliXpress for around 30 to 80 euro's max but I rather invest that in a new machine if I'm really F*cked.  Sad Confused

Does anybody have a gold solution for me? I'd be even more happy! Smile 

Ps. Whish I just left the BIOS since I had OSX High Sierra and Windows 7 Pro dual boot running.
