    Lenovo TD350 ThinkServer BIOS v505 Corrupted BIOS,

    Hello, the bios on my Lenovo TD350 ThinkServer got corrupted during a bios update, the bios restore function killed the Server.
    I need to flash the bios inside the MX25L12835F SOP8, i have already desolder the chip and solder it into my SOP8 adapter and read it with a ROM programmer.
    I use the innoextract 1.9 software to extract the bios file from the .exe file that i download from lenovo website, can you help me edit the Hex file (removing the Index part and resize the file)?

    This guy claim to have done it https://forums.lenovo.com/t5/ThinkSe...up/m-p/5123818 but he did not mention the bios file modification.
    I have also attached the "corrupted" 1.5 bios version rom that i backup to compare it.

    Thank You

      I was able to revive the server by removing this parts of the file, (see the attachments), flashing it to the ROM and Re-soldering it to the Motherboard.
      Now the Server works and it's updated to the last BIOS version!
      The dimension of the file should be exactly 16384KB.

        Lenovo ThinkStation P520 BIOS file needed
        by Forest79
        Hello,

        I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
        The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

        However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...

        Unable to extract bios file from Lenovo bios exectuable
        by survivalbloke
        I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the command
        Code:
        "innoextract 7wcn38ww.exe"
        it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.

        The trouble I'm having is that I'm not getting the newly...

        Bricked Lenovo IdeaPad 3 14ADA05 Need BIOS file for FN+R Crisis recovery
        by pcwhiz24
        Model: Lenovo IdeaPad 3 14ADA05 81W0
        S/N: PF2BZS7D

        I was having issues with this particular laptop where the NVME SSD would disappear and would not detect unless I took it out and reconnected it, then it would detect for only for a minute then disappear from BIOS. I figured updating the BIOS was worth a try so I booted into my HBCD USB and downloaded the latest BIOS file for that exact model. I ran the executable and everything went smooth, it beeped and then when it restarted, now it won't post, just black screen with fan spinning.

        I already have a CH341A programmer...

        Request for Lenovo 5-15IMH05H Type 81Y6 BIOS bin file
        by maanee11
        Hello Everyone,

        I have Lenovo Legion 5-15IMH05H (Lenovo) - Type 81Y6

        and I have encountered a Black screen on startup. I have tried the power drain and all sorts of tricks that were available online to revive it but no joy.

        Since I have already an expired warranty, I am thinking of flashing the BIOS externally. I have a Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, I need a bin file for the BIOS. The latest BIOS executable can be found here but I need the bin file to flash it externally.
