​It's seem to be you are using the wrong 16 to 8sop clip
16 to 8 pin only use 8 pin from 8 header corners pin of the chip
you can modify the one you have or buy the right one
the correct trace is on the clam pcb there is place to solder 16 pin chip follow the trace under pcb to match which pin of 16 connect to 8 pin
when you connect ch431a to computer i recommend you should plug directly instead of external cable
use the ch341a programming software to detect the chip

HP ProDesk 400 G6 desktop mini PC Bundle...

Hi, I have another HP ProDesk 400 G6 desktop mini PC bios got corrupted. If you could, can you teach me how to recover 400 G6 corrupted? because i have like 70 of it in my school.
Serial 8CC1241JFP
SKU 227Q1PA#UUF
Thanks again for the help....

I already edited the original bin file remove block BFF000 to BFF235. Re-flashing it into bios chip. it shows manufacturing mode is unlock prompt when boot up and all S/N, CT, SKU is missing but i can access to bios without entering password. S/N, CT, SKU, F.byte I can locate in backup bin. Using DMI to add these again. but one thing still urgent me is born on date is 00/00/0000.
Your bios provided i just check and it doesn't have S/N, CT, SKU, F.byte in it.
Monday I will try it. Because this computer is a company property so I have to be careful .
BTW: I'm not the one set...

there are 2 jumper on mobo and tried both but nothing, still ask for password to access into bios. Look inside bios file seem different than other bios for other HP model. It's an AMD board so maybe it harder to clear password? or the password store on other location?

Hi, I forgot admin bios password
Please help me remove it
