    I need some help, what do I need to reprogramming this type of bios with? Correct me if I am wrong, but I have the CH341A but it does not support it.


    thank you in advance!
    I just realized that it is possible to do it with CH341A, reading with MX25U25635F. Thanks to the comments above

        Hello,

        I am revisiting one of my first laptops I began working on and broke the bios chip (rookie mistake...). I unfortunately was never able to get any data off of the chip since it broke on removal. I have since gotten a replacement. Would anyone be able to provide a clean bios for this laptop? I am also a bit confused in regards to the bios chip. It is a GigaDevice 25R256DYIG. I can't locate it on any of the programmers I use. Info below. Thank you for any help!

        Lenovo ThinkPad L15 (Gen 2?)
        Model: 20X4SBDN00
        Serial # PF3WEDZR
        Board: HL4A0/HL5A0 NM-D271 Rev: 3.0

        I have tried using online bins, but every one I use is ineffective. PC wont turn on at all, just blinks 3 times when plugged in. Due to not finding the chip in the programmers, I used CH341A Programmer and it came up as a W25Q256FV. I have been trying to use that but no luck. Any help please is appreciated!

          Issue has been resolved! I was able to find the chip using NeoProgrammer. I also used a old clean bin that I had from a previous L15 and the laptop booted into self heal and is working!

                So far I've been a silent reader, but now I need your help

                I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
                I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
                The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

                Should I buy a Lenovo Thinkpad E495 with bios password?
                by RMDUiFT
                Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

                I have a few questions:

                Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)
                by akwky
                Hi!
                Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).

                Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...

                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....

                Help to get Lenovo BIOS bin file for Thinkpad T560
                by maanee11
                Hello Everyone,

                I have Thinkpad T560 Which has corrupted BIOS. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need a bin file for the BIOS. I was able to extract the .exe file of BIOS from Lenovo given here in this link:

                https://pcsupport.lenovo.com/au/en/p...me=BIOS%2FUEFI

                In the extracted files, I see that BIOS containing file has extension .FL1 and I need to extract or convert it...
