    ENCONTRAR DATOS DMI EN EL CHIP BIOS IDEAPAD5 15ITL05 / FIND DMI DATA ON IDEAPAD5 15ITL05 BIOS CHIP

    Hi, Im trying to find the area on the chip that contains all of my laptops information, but I havent found it. The laptop won't turn on anymore. I was updating the BIOS, and it was supposed to reboot itself, but it wouldnt turn back on. I ve tried every possible solution, every alternative on Lenovo forums, everywhere; I ve taken it to technicians, and no one has been able to fix it. I've already read the chip that contains the BIOS (Winbond 25Q128JSVQ) and searched for my laptops data, but they're nowhere to be found. I only find scribbles and lines of text indicating errors. Has anyone had a similar case? If so, where can I find the DMI information for my BIOS? Or if not, is there a way to reinject it into the chip?
    Sorry about English, Im bad with the language.

    Your laptop has its BIOS split into 2 chips, 8MB + 16MB, there's also a 8MB chip (maybe W25R64FV or similar), read this one too
    DMi data is encrypted, find LENV with hex editor on 16MB chip, then copy both blocks
    It looks like this

    As peste would say, you have everything you need at post # 14, that's the offsets you need to copy from your backup to the clean BIOS

    You can use this tool to decrypt DMI info
    https://github.com/Shmurkio/LenovoDMIDecryptor/
    Usage: LENV.exe bios.bin -decrypt decrypted.bin

      Se ve así

      Comopezdiría que tienes todo lo que necesitas en la publicación n.º 14, esas son las compensaciones que necesitas copiar de tu copia de seguridad a la BIOS limpia

      Puedes usar esta herramienta para descifrar la información de DMI

      Hola,

      mi laptop tiene 4 chips. Un Winbond 25Q128JV, un winbond 25QR64JV, un winbond 25Q80EWNIG y un ATMEL 45DB081D SU954 pero al buscar LENV, solo aparecen 2 resultados y ambos están ubicados dentro de muchos garabatos.

        Please write in english, you can copy paste to Google translate, it's the forum rules here

        Yes, it's supposed to look like that, that "0xBE" character which is repeated, it's the encryprion byte, it changes for every laptop even of the same model, what you call "scribbles"/"garabatos" copy all from 42E000 to 42FFFF including the "garabatos" and Paste write on the clean BIOS at the same offset (Pegar escribiendo, Ctrl-B)

        I decrypted your LENV blocks with the tool linked above, someone flashed a different BIOS, model "Lenovo XiaoXinAir 15ITL 2021", it's a China model, type 82GM, S/N doesn't match yours, your original data including Windows key is lost forever, sorry

        Also the serial you posted PF2L7LF2 belongs to a Thinkpad T14 Gen 1, check again

        Only flash the W25Q64 and the W25Q128 with the BIOS from post 14 here: https://www.badcaps.net/forum/troubl...tl05-bios-file

        Or the BIOS from post 8, flash both https://www.badcaps.net/forum/troubl...62#post1757162

        Should work, but will display INVALID serial number, model, and MTM, if you want you can copy the data from the 16MB BIOS on post 13, decrypt it, edit serial and MTM, encrypt again, flash it
