    Lenovo m92P iq77t bios \ winbond dumo files

    This is an absolute longshot however would anyone have a functioning m92p with the iq77t motherboard in it? The system I have here was sent to me after a bad bios update. The user tried to correct the problem with their programmer but made it worse.

    I can pull data from the mx25L1606e & the MX25L6445E however the winbond 25q80bvsig is FF and empty.

    Would anyone have the same setup and able to share their dump files so I can see if I can get this unit working once more?

    Thanks!

              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.

              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 2H1703-27220F Rev. A Marked as U2501 on the motherboard.

              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...

              Lenovo IdeaPad 3 - Hard Disk not recognized in BIOS
              by mkdj
              Dear all,

              I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

              Here the steps I have taken to fix the laptop:
              - downloaded latest BIOS from Lenovo Website...

              [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
              by hyperwood
              Hi everyone,

              Iā€™m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.

              The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.

              I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā€“ and the last 2MB in those files are just FF FF FF....

              āœ… What I need:
              • A working 2MB BIOS dump
              • Matching NM-E471 Rev. 2.0, e.g. JY575
              ...
