            Hi , having trouble using an Neo programmer when i write the patched bios sometimes it keeps on not responding but when it finished on many tries to patch the Lenovo T470s bios, when I turn on the laptop the screen is black and there is a melody.
            i followed this tutorial video in yt (https://www.youtube.com/watch?v=s9XlN2Hl0ag&t=521s) instead of Asprogrammer i used Neoprogrammer to detect my chip model : 25Q128JVSQ (W25Q128JV WINDBOND)

            BIOS PASSWORD REMOVE
            Thinkpad T470s
            i5-7300U
            SN 20HGS0KE00
            chip model : 25Q128JVSG

            also attached a dump bios file that i made in neoprogrammer,
            please someone help me to patch the bios file or give me a correct programmer software as i use CH341A.
            Thank you

                Summary of BIOS Whitelist Removal Problem Lenovo Thinkpad T560

                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....

                [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                by zenius
                Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                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...
