Need help recovering Lenovo ThinkPad T450 's bios
Hello! I am wondering if its possible to make my Lenovo T450 work again. The problem is - I tried to flash the bios and remove the administrator bios password but made a terrible mistake -
I used a CH341A Programmer with it's official Windows software. But turns out this software has a bug and can't correctly work with "W25Q128.V" chip. It fails to correctly read from and write to a chip. Which was also noticed by a user "Weelcup"
So I used this program and, of course, I didn't succeed. Not only it failed to correctly write, but the ORIGINAL dump is also corrupted now and doesn't work when I try to flash it back.
I made multiple copies of the original dump and they all differ from one another - I noticed it before writing to a chip but failed to realize I would need the original dump again...
Later, I decided to install Ubuntu and use flashrom instead of the official software on a second identical T450 I have (thanks for this advice to a user "mockingbird" in a previously mentioned thread).
Everything went perfectly on the second laptop, using LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal I successfully patched the bios and restored the original - admin password is gone.
But the bios from the second laptop doesn't work on the first one. I also tried a couple of bios dumps I found on this forum none of which has worked.
- Laptop turns on - no image - shuts off in a couple of seconds.
- Or, turns on - no image - beeps 5 times - shuts off..
I guess I need to restore the original but I am new to all of this and don't have a clue on how I can restore it from this state.
So, If anyone have any ideas I would greatly appreciate your help!
I will attach corrupted readings of the original bios dump.
Chip is "W25Q128.V"Comment

Good day, everyone!
I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.
I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the... -
Hello all,
I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful.... -
