Resolder your bios chip, be careful about resistance/caps near his legs

Thanks martha februarini & lapfix For your kind support

solved by rebuild new bios region in bios section and flash that in same chip
it means there was no administrator password
but i try 3 bios from online like vinafix and all there was no display
so i have hope only from the original backup only
and finally job has done

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"
