    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!

                    Hello everyone,

                    First, the data in brief:

                    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:
                    • If I would buy this laptop and have

                    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

                    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...
