i then flashed this back to the winbond chip and verified the file which matched but the administrator plus other user names in the bios still remains. what could i be doing wrong? and is there anyone who can help me out?
post the backup of the bios, the original bios of the laptop.

it is not good even now..check with the HxD program the copy you send..enter the copy of your bios and a correct copy of the laptop bios (find on the forum) in the HxD program and make the comparison ..

Hi everyone.

In the UEFITool, I am trying to empty my first padding in the BIOS region. After extraction, I use the HxD program and use the "Fill selection" command to replace all data with FF. Next, I replace the padding with the modified file. But for some reason, the file sizes differ and I can not rebuild my bios file due to the size difference.
Can anyone guide me on the problem?

Problem fixed, my bad. It is a little tricky modifying padding size.

hi everyone, ok I need some help so here goes..I have a hp 850 g1 which has an administrator password and just below that in the bios there are two more users. I have bought a ch341a and I also have the hp unlock.exe..i have desoldered the larger of the two chips that are on the board. I think I may have bought the wrong sop8 chip socket as attached because it's the 150mil version but my bios chip doesn't seem to fit in it causing my ch341a to produce ff and ffff when trying to detec. do I need the 200mil? also the chip I have is 25q128a 13eco 99chn 42005 and is 8 pin what is the more reliable software that will have this chip number in its database that actually works or confirmed working with a hp 850 g1? I have about 300 of these laptops to work on.
