    Lenovo T520 BIOS needed.

    Hello. I need a stock Lenovo T520 BIOS image as my modified BIOS will not produce a working coreboot image.

    The T520 and T520i share the BIOS image.

    I need the 8mb MAIN.

    Thanks!

    You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

    Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

                  are you able to share the precompiled coreboot file?

                      ^ The T520 and T520i share a BIOS, however due to differing hardware addresses coreboot can't be compiled for both. I built coreboot for the T520i, if you have that, my coreboot build will work. Otherwise, it won't. If you still want it, i can upload it.

                                      Unfortunately I reflash bios with whitelist removed by software. I did not make old dump unfortunately. After flashing bios is failed

                                                                                  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....

                                                                                  Hi everyone,

                                                                                  My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
                                                                                  Laptop stopped booting entirely.

                                                                                  I used a CH341A programmer to dump the corrupted 16MB BIOS.
                                                                                  i then attempted the following:
                                                                                  1. Downloaded stock BIOS BHCN39WW from Lenovo
                                                                                  2. Trimmed it to 16MB
                                                                                  3. Extracted the BIOS region from the corrupted dump
                                                                                  4. Extracted the BIOS region from the stock 39WW
                                                                                  5. Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
                                                                                  6. Injected back my LDGB / DMI
                                                                                  ...

                                                                                  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...

                                                                                  I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

                                                                                  Here the steps I have taken to fix the laptop:
