Hey,
sorry if I caused any problems. If BDMaster used the bios dump in my results.rar (if that's what it was) then that would be different from yours.
But if you go to MDL (mydigitallife) forums in the bios section, there is a sticky post about an undocumented Insyde bios recovery method there.

Anyway, thx to BDMaster for the mod, I will not test it today though, but tomorrow if it seems safe

I checked your Bios backup and Staenos too comparing and They are different into DMI region data
This Laptop is selling into two configurations :

1. Win7
2. Win8

So It's possible that Stenos has different S.O. and may be different MoBo configuration !

Now You try for first thing to reset CMOS removing Battery from MoBo or using the jumper
near Battery if present.
Then let me know, I will prepare an Recovery Bios file to try the Laptop Bios Recover !
Regards

There are two SKU different :

Stenos Bios PSCBWE-09100SN5

TOSHIBA.SATELLITE C850-1G3.PSCBWE-09100SN5.5D037213S.xxxxxx

Type1Family PSCBWE-09100SN5,R17414NHX00.HSJ-ZcevUZsII.yN6Kd+WvBJ3ui.p-T9FL3zW+UF9

R1skNt Bios PSCBYV-03U002AR

TOSHIBA.Satellite C850-B718.PSCBYV-03U002AR.XC541571R.xxxxxx

Type1Family PSCBYV-03U002AR,TI309649XMB.-5EBh3MenI4d1.mA5ixOwPuMPOy.TTfxdRKPf3ama

So it's normal Brick result !


Let me know which is your Windows S.O. 7 or 8 ?

it was my fault dont you worry.

i asked my friend and he tells me you can change the bios IC chip this is the last siloution i will try and then i will flash the right bios i hope

Ok there are two files :

1. Win7 recovery bios

http://rghost.net/7qGrtJqwS

2. Win8 recovery bios

http://rghost.net/65nNQrvPY

Choice for your laptop the version applied for your S.O. then prepare an USB Stick
not bigger than 4 GB Format it into Fat32 and copy into the Recovery File (file extracted
= unpacked) Not folder only the FX64.fd file !!!
Then use the Recovery Procedure :

- Shutdown the netbook (notebook)
- Remove all peripheral devices
- Remove battery, Remove AC power cord
- Press and hold the power button for 10 seconds (battery and AC power still out), then release
- Put the USB Memory Stick in the USB port
- Hold "Fn" + "Esc" and plug the AC power cord in
- Now press the power button (whilst still holding Fn + Esc).
Wait until the fan will run, then release "Fn" + "Esc" keys
- The fan will run for about 2-10 minutes and the USB drive activity LED will blink
- I think the netbook rebooted automatically. If it doesn't, unplug the AC power cord once the fan has turned off

The bios should be updated with the modified BIOS, and boot as per normal.

May be on Toshiba You have to use different Keys combination so try to use too

Fn+ESC, Fn+B, Fn+F, Win+B

Let me know
Regards

P.S. If It will not work then try to rename the FX64.fd as Insyde.fd or Bios.fd and try again !

[stenor]

Success

Right now I'm trying to figure out if I can change the fan behavior when plugged-in ac.

Anyone know what the tc1 tc2 tsp etc are?

If i get this working I will surely make a donation (well probably anyway).
