Re: hp elitebook 840 g4 need password unlock

This is absolute BS.
Don't mislead people with such nonsense.
In each dump the area to be edited is located in different places, so specifying block addresses is pointless.
So at least you need to specify what you mean by pointing specific keyword or pattern to be searched for.Last edited by Vesko356; 08-16-2021, 08:32 AM.Leave a comment:

Re: hp elitebook 840 g4 need password unlock
i FOUND THE SOLUTION:
1- OPEN BIN FILE (16MB) using 'Hex Editor Neo'
2- Save as a copy (for example 'cleared file.bin')
(Dont modify backup, you can need it!!!)
3- Replace all caracters between 00b76064 and 0009c56b by 'ÿ' or 'ff' in hexadecimal.
4- Save again
5- Flash rom circuit using the new file 'cleared file.bin'... Enjoy

by Modify_incI have a Inspiron 11 3185, and in the BIOS setup under Security it shows "Locked Setup", which limits pretty much everything in the BIOS. I'm using bios-pw.org to generate the codes for the hash, but they never work for the Locked Setup password. The codes generated for the System password and the HDD password work fine, but the code for the Locked Setup password always fails. I don't understand, if it works for the first two, why is it not working for the Locked Setup p/w? Since I can't disable it, anytime I reboot, even after a Windows update, I have to go through the hassle of generating...

by zeniusHello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...-
