      BIOS original: is the BIOS file in your device, containing DMI and Windown Key of that device.

          You have to buy a programmer RT809H , CH341A (this is the cheapest one) and many more.

                Now the device isn't booting at all now. i also can't write the old dump back to the chip. does this mean the chip is damaged and need to be replaced?

                  It is very possible. And you should check the small components around the bios chip to see if they have moved or disappeared.

                    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...

                    BIOS Request - Lenovo Yoga L13 Gen3 (AMD)
                    by maeson
                    Hi dear Badcaps-Community,

                    Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
                    I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)

                    The Device is a Lenovo Yoga L13 Gen3 and I was able to identify the following specifications:

                    Lenovo Yoga L13 Gen 3 AMD:
                    Lenovo Modell: Type 21BB

                    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 Yoga X1 Gen4 - Faulty Bios or what is going on?
                    by AYsys
                    Hello dear forum members,

                    I own two Lenovo Yoga X1 Gen 4 laptops. One of them had a touchscreen problem, and I tried to fix it by externally flashing the BIOS. Unfortunately, I didn’t save the original BIOS and accidentally flashed it with a faulty one. After that, the device stopped working completely.

                    I then had the idea to make a BIOS backup from the other Yoga X1 Gen 4 (same hardware) and flash it onto the non-working device.
                    Nothing was flashed here — the BIOS was only backed up.

                    I created the backup using a CH341A Black programmer and NeoProgrammer....

                    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....
