    post the contents of the bios chip even if it is corrupted..

        The bios chip must be unsoldered from the board before writing or reading..
        do not use the clip, you may have errors..if you do not have anything to unsolder it with,
        solder wires between the programmer and the bios chip..

        you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

            I have an HP Chromebook 11 G6 EE that is enterprise-enrolled. I don’t have the school’s login. Is there a way to deprovision or unenroll it? S/N: 5CD9244Q69

              We can`t help unless you post your bios backup. If the bios chip is WSON8 buy a WSON8 pogo adapter or solder wires. A SOP8 clip will not work with a WSON chip.

            I have CH341a programmer. Would it not work for WSON8?

              M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.
              by hotcrossedbuns999
              My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
              1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
              2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
              3. I could only locate two chips that look like bios chips. Could someone verify this

              Thinkpad t480s, completely dead after BIOS flash using CH341A programmer
              by what_1282105
              Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....

              HP Pro x360 Fortis 11 inch G9 Doesnt boot after flashing bios

              This motherboard has 2 similar chips. One is on the front marked with BIOS SKT "Winbond 25Q256JVEN" and one on the back marked with U351 "Gigadevice 25B256EYIG". I ignored the one on the back and only desoldered front chip. Made a backup, made sure the reading was the same with another 3 backups.

              In search of advice for flashing bios via efi shell
              by bql
              Hi Badcaps,
              I'm having the same Notebook and problem as in this topic:
              HTML Code:
              https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/3601016-need-bios-for-clevo-pd50pnp
              I'm assuming that flashing the provided bios in this topic would solve my problem.
              The only thing i can boot to is EFI shell
              How do i flash the bios image in the EFI shell ? / Can i use any flash.nsh or is the executable interconnected to the bios image? ( i cannot find any bios related files in the internet...
