Bios Bricked: Sony Vaio VGN-AW11XU

[RodentVienna]

Hello,

I have applied this Bios:
https://forums.mydigitallife.net/threads...ost-761866

i booted DOS, and ran AFUDOS.EXE R1054Y2S.WPH
(unfortunately without /P )

The Laptop now stays black-screen when power-on.


I tried the procedure:
https://www.bios-mods.com/bios-recovery/...-recovery/

I ran Andy's Tool, and it says it is an Inside BIOS; recovery filename: Y2.rom

I formatted an USB Stick (old model, 1GB size) with FAT16,
and put Y2.rom into root FS.

The laptop has 3 USB ports, and I have tried all 3 ports with all known Keyboard-shortcuts, e.g.
$nokey-|FN-|Win-|Ctrl-|Alt- Esc|B|F|R|Home

In any case, the USB Stick's LED blinks once upon power-on, but then nothing.
(it should blinkg, when bios file is read, right?)

I have been 3 days on forums of MDL and here, and Sony Vaio Notebooks seems to be difficult to recover, with not much information and usercases available.

I am really looking for guidance here;
to me it seems I just miss the correct KB-shortcut to start recover procedure upon poweron...

Thanks for any help!!
