Hello, i have a BIOS startup password on my HP Spectre x360 15-df1004ng.
Can someone remove the password?
I made a dump with CH341A.
The BIOS IC is a CFeon QH128A-104HIP

Wrong chip, maybe you have another chip or your device can unlocked by the Hint after enter invalid password 3 times.

If i enter 3 times an invalid password it ask for a hp sparekey, which i dont have.
I found another chip, Winbond 25Q80DVSIG. There is also a WSON 8 Chip Winbond 25X20CLIG. But i dont have a probe for WSON 8, so i have to solder. So i first wanted to try the 25Q80DVSIG Chip.

Is there any other chip (SOIC/WSON) except those 3 (25X20CLIG-25Q80DVSIG-"Your 16MB chip").

No, only those 3 chips. The rest of the chips are mostly mosfets

I found some informations about this model on this site, maybe that can help.

The difference between my model and the df-0013dx is, that i have a CFeon chip instead of the BIOS chip winbond 25Q128JVSQ.

I flashed a clean bios from the newest HP bios firmware. Now the laptop starts without password, but it lost serial number, windows key etc. and says, that " Manufacture Programming Mode is in Unlock Mode ". What is the best way, to enter all data from my dump with password into the clean bios file?
