Hello friends!
I've got a latitude 5431 with no sign of life.
I opened the computer and, of course, someone played with the SOIC8 BIOS (16MO).
I dumped the BIOS and... it is VIRGIN, no data in it!
Could you rebuilt a correct BIOS for me?
Here is the 32MO dump (fortunately, this chip was not unsoldered :-) ).
It is a Latitude 5431 (i7) S/T: 6QVWJR3
motherboard HDB45

So I have to flash BOTH files (16 and 32), with, of course, the modified 32 one?
PS: for the adresses, it is 009230000 to 00A02FFF?
Because HxD Editor does not recognize these adresses ( 0x923000 to 0xA02FFF BUT recognize them with a "0" instead of "x")...Attached FilesPremium supporters get full download access and other benefits.

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -

Hi everyone,
Iβm working on an HP 255R 15.6" G10 Notebook PC that has a BIOS Administrator / Setup password I cannot bypass. I can boot Windows normally, but F10 is completely blocked unless the password is entered. I do not know the password.
This is not a PowerβOn Password. This is a BIOS Admin password stored in NVRAM, and the system will not allow BIOS access at all.
Iβm posting here to get help identifying the correct procedure, dump, or method needed to clear the password on this model. System Details

I have 2 computers with admin password on BIOS. Standard code generators don't work on this new platform.
I have dumped both SPI chips from the motherboard (16MB and 32MB). Could someone please help me remove the password or clean the ME Region?
