Hi.
My Lenovo did not start and stopped giving video. I removed the Winband 74M12JWSIQ chip and the programmer shows it as W25Q128FW [1.8V]. I made a backup copy of the BIN but I can't find a BIN that works.
Can you repair the copy of the BIN file?

I made the transfer of DMI to new bios. DMI is encrypted as you see in picture. try this one:

Hi volinakis,
can you maybe explain which parts of the BIOS you need to transfer from the dump to the new one to transfer the DMI info (considering V15 G2-ALC)? Also I'm very much interested in how to decrypt the info like you did in the picture.
Kind Regards,
tandoori

there is a Lenovo DMI decrypter in this forum
https://www.badcaps.net/forum/troubl...-dmi-decrypter

DMI, as peste and others mentioned here is from 1000 to 2FFF, 8192 bytes. Search for text LENV

Hi,
sorry, I did not find that info although it's on the same page. Well, thanks anyway for repeating it. About the decryptor: I use Linux, so I might try WINE to use it, since it's only an exe file and the source code calls Windows.h headers, which implies that it is not easily portable to Linux. Thanks for that though, also.
Kind Regards,

Yo, I have this backup of the bios done with "SctWinFlash64.exe" before flashing,
IdeaPad 3-15ALC6 Laptop - Type 82KU, rev 3 board
S/N: PF34TEHD

I'm sure, there are no reading errors, as I have done two readings and they have the same data

Can I use this backup to make a new bios following the #4 post?
Or flash directly this bios?

Anyway I have a ch341a and a raspberry pi 5, the raspberry pi 5 is better suited for this right?

you have everything you need at post #56...

[FachiroDiStriscia12]

you have everything you need at post #56...

Sorry maybe I'm dumb, but post x56. doesn't contain any instruction and for some reason it does cite itself.
Anyway I have made this bios file removing the headers and changing the dmi data, is it correct?

what didn't you understand??write the bios on the chip from post #56..you also wrote the DMI interval there...what's the problem?...the bios is ok...
