write the original content back to the chip, see what happens...

I wrote the original file to the chip. It is booting fine. I think there is some issue with the patched file. Is there anything else you want me to try.

1st boot, press F2, write service tag, disable Absolute, save, restart.
2nd boot press Alt+F to exit manufacturing mode.
Good luck.

I tried this file. It did not worked for me. I will try another file posted above to see if it works.
Is there any easy way to read write wson8 chips?? Like any probe which can be used on dell laptops as bios chips on dell 7410 does not have legs to make contact with a probe. It is really hard to desolder and solder chip again and again.

Hey guys, could some kind soul remove password from my Bios file please ?

I read the XMC-QH256BXIQ Bios chip using 2 programmers, CH341a , and a XGecu TL866ii+, verified and saved 2 copies.
I tried running both copies through the various Dell password Utils, but it just kept saying, "intel Signature Not Found" , or, "8FC8 Hex Pattern not Found"...? What am i doing worng ?

• Is there another Util i can use to easily find the Bios Passwords myself, and to save me annoying you guys ?

try again with TL866II, but like this...
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..
and post again..

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