Model : Toshiba R930-1FE
Bios update link : http://support.toshiba.com/support/viewC...Id=3519735
Service manual : https://www.manualslib.com/manual/813546...-Z930.html

Hi after a failed attempt to flash bios, I bricked the laptop. Now I try to find the correct name for the Bios and configuration USB KEY. 

The service manual explain the procedure but when I make it he enter in the rewriting bios mode and the USB key blink twice and the laptop don't shutdown automatically, I assume the correct Bios is not catched. 

I did this procedure in the past for an Insyde H2o bios but the file was in .fd format not really like here.

Procedure : 


Rewriting the BIOS
1. Set the system to boot mode.
2. Turn off the power to the computer
3. Remove the external cables and cards
4. Set the USB Flash Memory containing Bios rewriting data..
5. Turn on the power while holding down the tilde(US keyboard)/tilde hashtag(UK keyboard)/²>"racine carré" key(French Keyboard) character key until LED blinks
6. The BIOS rewriting starts
7. When the process is completed, it the system automatically reboots.

Can you help please ?
