    Lenovo M710q need bios modification for 8 and 9th gen CPU

    Hello.
    I downloaded several modified BIOS for Lenovo M710q and work but most of them are old versions and one gave me "LAN adapter's NVM configuration is corrupted" on boot, so i decide to flash the latest official 1.5A version and upload it here for someone to modify it and accept 8 and 9 gen T cpu.

    Uploading the one that worked better too, in case you want to copy the microcode.

    Thank you in advance!

    Managed to get the tool that does the job but still i can't do it right, tried already twice but no post.
    I don't do correctly the HxD part and the patching with microcodes i guess.

    Directions i got:

    Boot to BIOS take a copy of the page with the UUID and other data
    There is an app that extracts it but not had a chance to look at this yet.
    You'll probably will need to to put the data back as it will all go after flash

    Backup your current BIOS (16MB) with CH341A programmer, there are apps that might do this also but can't guarantee results
    Keep a copy of this BIOS somewhere safe and a copy to work on
    Grab newest M710q BIOS (8MB) from Lenovo support
    Place M710q BIOS in the 2nd half of the backup BIOS (8-16MB region) use HxD app (whoops you'll need to DL this forgot to add)
    Run 'Coffeetime 0.92'
    Patch all every thing you can incl 'Extra' tab
    ME leave this alone, won't upgrade anyways
    VBIOS+GOP update both to highest versions, have update to 228 ticked
    Now with the M700 you only seem to have room for 3x Microcodes choose as you see fit, tick:
    506E3 = Skylake
    906E9 = Kaby Lake
    906EB = Coffee Lake B0 CPUs (these max out at 4 oores) and don't need CPU pad mods
    Choose others as you like, 906Ex are all Coffee Lakes with 6 or 8 cores but need CPU pad mods

    With 'UBU' you can update the Network ROMs too but from memory the M700 gives an error when doing it
    Not sure if you can just ignore it
    You can just leave it as is, LAN works without the update

    take out Coin battery
    Flash Modded BIOS (16MB)
    Put battery back in
    Plug in and wait, it may reboot a couple of times as it sorts its self out, to who what why it is

    If black screen try another DP port
    If nothing happens (it should reboot at least once) something is wrong, reflash another BIOS or original backup

    If no SATA port shows and machine won't boot as can't see drive
    Go into BIOS on exit page set the OS default to 'YES' when machine now boots it should say 'Scanning for Media', ESC out if it goes through network boot options (can be turned off in BIOS)

          Summary of BIOS Whitelist Removal Problem


          Problem:
          I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
          Initial Findings:
          • My current BIOS version is N1KET58W (1.45).
          • I have a CH341A programmer and have successfully created two full backups of my BIOS.
          • I have the ability to use command-line tools on a Linux machine.
          Troubleshooting Steps & Conclusions:
          • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
          • I concluded that the

          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 Y540 – Need help repairing BIOS after bad downgrade
          by gestalt.exe
          Hi everyone,

          My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
          Laptop stopped booting entirely.

          I used a CH341A programmer to dump the corrupted 16MB BIOS.
          i then attempted the following:
          1. Downloaded stock BIOS BHCN39WW from Lenovo
          2. Trimmed it to 16MB
          3. Extracted the BIOS region from the corrupted dump
          4. Extracted the BIOS region from the stock 39WW
          5. Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
          6. Injected back my LDGB / DMI
          ...

          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...

          Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

          Hello everyone,

          I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

          This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

          I have opened the laptop and identified the main BIOS chip...
