Toshiba l50-b-2cr

[Jovica123]

Hello my friends.
I was playing a little bit with bios on this laptop,but before everything i have created a backup from bios that was working.
But after trying to flash some bios bin files, none of which worked,i tried to flash original and then laptop was not powering up.
I think I damaged the bios on this laptop, while reading the bios flash.
Motheboard in this laptop is : dablidmb8e0 rev:e
I tried few bios bin files from this site with this motheboard and nothing was working.
Except one i found on remont-aud net,it turns on but with some horizontal lines.I'll attach one picture.
I know it's damaged because when it loads in "Intel Easy clean me" it says "Invalid input file original bios backup.BIN"
Thank you,and sorry for long post !

I alredy tried this bios file,laptop turns on but black screen.
Yes,i know it is PSKTCE.But when I've already tried every bios PSKTCE i can found,then I tried everything, the only condition was to have the same board model.

I forgot to write that I don't have the original flash for it.
Original flash is GD25B64BSIG,i have MX25L6405.
Please anyone,help me !
With my original bios backup,laptop can't turn on,without any lights,nothing !
But with every other i tried,laptop turns on,but black screen(bios from motheboard with same model number).
If anyone can modify my original bios backup,please help me !

Re: Fijutsu Siemens l50-b-2cr

Your original bios is too corrupt,did you backup using a clip or desolder it.If you`re using a CH341A try some alternative software,and buy a new bios chip,one thats in the supported list.

Flash chips in VSCC table:
1F4700 (Atmel AT25DF321)
EF4017 (Winbond W25Q64)
1C7017 (EON EN25QH64)
C84017 (GigaDevice GD25x64)
374017 (Unknown)

Re: Toshiba l50-b-2cr

I made a mistake,i desolder it and then used a clip,i will post a picture how i did it.I have rt809h programmator,and this is not my first laptop on which I programmed the bios.I sucessfuly unlocked lenovo t440 and yoga 3.
On lenovo laptop you must have original bios bin file,but on these laptop hp,dell,toshiba it can work when you download from internet.
I don't understand why on this laptop is black screen.
I found winbond W25Q64BV,and I write your file in it "PSKTCE ME_CLEAN".
Laptop turns on but black screen.
It is not at all clear to me why this is happening.
Please answer to me,thank you !

I managed to fix it.
The problem was in flash.
I write bios bin file from this link on winbond W25Q64: https://www.badcaps.net/forum/showth...dmb8e0+rev%3Ae
