I found a working h5511 donor, decided to remove the bios dump and transfer it to the old one. However, the bios dump is all 0xFF. The laptop owner does not give permission to solder the bios. tell me how you took the dump, with what program? -
how do I remove the protection from the chip?

I press the unprotect button, but nothing happens. The program switches to the removal mode, the green RUN light on the programmer lights up. So it hangs for an hour, but the progress bar is zero

Are you sure it's not a bios?

I can't do this. there is no bios backup. when I read from the chip, everything is "ff ff" like a dummy. I tried to find the dump bios but all without success

there is no backup since everything was done from under windows.
now I'm trying to use the CH341A programmer. I've tried using TianoCompress.exe , to get the bin file, but I think this is not correct. When reading through the programmer, FF is everywhere.
Chip: Winbond 25x10clnig
when I try to turn on the laptop, it turns on and off several times.
The screen does not light up

Hello, everyone !
does anyone have a bios dump for this laptop? I was updating the bios through Windows and the Internet was gone by 5%. The laptop doesn't turn on anymore.
or is it possible to convert a bup file to a bin file. when i open *.bup file by winrar i get *.upd file 28 MB. BIOS can't be that big.
