    Problems flashing BIOS for supervisor locked Lenovo V15 G4 IRU 831A laptop

    There was an error... Aborting......I'm using another Linux Laptop with Zorin OS...to try and patch my Lenovo V15 G4 IRU with above specs....It originally had Windows 10/11 installed and converted to a dual boot Kali OS/Parrot OS system. I may have used the wrong lenovo_autopatcher_0.2 (I believe was posted by @knucklegrumble....I am out of ideas and flat broke so i cannot afford another fix (spent it all as an e-com entrepreneur does) any help from anyone would be GREATLY appreciated.....
    • Laptop Model: Lenovo V15 G4 IRU
    • Issue: Forgotten supervisor password.
    • BIOS Chip: GD25B128E (or GD25B128B if that's what flashrom -L reported).
    • BIOS Version: The exact version you noted from UEFITool.
    • What you've tried: Mention you've successfully dumped the BIOS with CH341A/flashrom, and you've tried a lenovo_autopatcher but it gives the "corrupted or not valid dump" error.
    • Crucially: Attach your backup.bin file to the forum post. This is the file they will need to analyze and help you with.
    I have attempted your amazing instructions on how to do a dump then patch and flash the BIOS with the CH341A USB Programmer but get the message....Using UEFIReplace to inject 2 DXE drivers...
    [1/2] LenovoTranslateService (GUID 826bcf56-bac4-43f4-8ea1-8cdf0a121abd)
    first_dump.bin is corrupted or does not contain a valid dump.

    The Autopatcher does not work with this model. Post your original backups and someone will help.

      Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
      by Wahaz
      Hello,

      I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
      So I thought it was a Bios problem.
      I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

      Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
      by grimacelord
      Hello there.

      I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.

      History:

      1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.

      I searched for this error online and discovered...

      Lenovo Thinkpad X13 Gen 3 AMD locked bios
      by fulaphex
      hello friends - I have purchased a used Thinkpad X13 Gen 3 AMD variant and only after making the purchase I realised that the BIOS is locked. I have spent a bit of time browsing the forum and from what I understand it's possible the modify the BIOS that is currently on the machine and remove the password from that BIOS. For dumping the BIOS from the laptop I have ordered this ch341a programmer. Below is a photo of the password prompt:


      I have taken the cover off the laptop and I found that "serial number" is "GM-0358MB" and "type number" is "21CN-S19U00"....

      Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
      by jendkkd jeje
      So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

      I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...

      Lenovo X1 Yoga 1st Gen (model - 20FQ) with a locked BIOS
      by opensourcefan
      Hey all, I have a Lenovo X1 Yoga 1st Gen (model - 20FQ) with a locked BIOS. I would like to unlock it.

      Currently I have it apart in all its glorious bits looking for the security eeprom that I can't find. Plan was to jump it. Next step I think is to pull the BIOS IC and flash a decryption file to it?? I'm a bit confused on that process.

      1. Pull the BIOS IC,
      2. Read and save the original locked file
      3. Flash the decryption file
      4. Install and boot up and remove password from BIOS
      5. Remove BIOS IC again
      6. Flash Original locked...
