Re: HP BIOS unlock tool
Fair play, I thought that, but .....you know...I was hoping it wasn't fubar.
I've been playing with the Ch431 on scrap chips, just reading them and stuff (getting better with the clip), also started using NeoProgrammer instead of the included one.
Checked my pins and they all seem to be 3.3v so I don't need the 5v hack.
Next question, does anyone have an 840 G2 BIOS I can try an flash? Failing that I am going to have to de solder aren't I? Then either flash an image or buy a new 25Q128A?
Cheers,
D

Re: HP BIOS unlock tool
I ask the Great Nobles for help.
I can not reset the password for the HP645 G4 BIOS. I tried using this utility. The chip is sewn, but when turned on, the password for entering the BIOS pops up all the same.
Maybe someone can overwrite this password?
Bios attached below.

Did you put HPUnlocker.exe in C:\ or D:\ directory? If your directory has spaces or maybe some strange letters in it, it will give the error you wrote as I wrote before.
can we make a bios dump that just make some line clear and the other line remains untouched
for removing password when we have at least 100 pcs from one model with bios lock problems

Re: HP BIOS unlock tool
Hi all,
I would like to have an answer for some little details before flashing a bios.
First of all I read all 53 page of this thread but didn't find my answer.
I would like to know if the bios provided by hp in their bios update package are an entire bios ? which would be superb for my need.
Second, does your unlocker @RethricalCheese work for a HP Z440 ?
I looked and it has a W25Q128FVSQ chip which retain the bios password even after a cmos reset, but luckily no trace of a second chip.
I will be using a CH431a with neoprogrammer ( it seems like the most appreciated here ) like everybody but I will be stuck with the clip as by budget cost I can't afford a desoldering tool.
Thanks

Re: HP BIOS unlock tool
Thanks for the fast reply,
Unfortunately the green jumper only remove the power-on and startup password not the admin password
I also tried the boot block recovery but it failed to change the bios ( might be because it's not the entire bios as you said )
If I have to use your unlocker do you think it will work ?
The HP Z440 is a machine from 2015 but being a workstation and not a laptop, I would like your confirmation.

Re: HP BIOS unlock tool
Hi, i'm back with some news
First my ch341a will arrive in late afternoon in my country ( currently 11am )
Second, @RethoricalCheese, your jumper may remove the admin password BUT I dumped the bios config via the hp bios config utility and found that this jumper can be disabled
Here it is in attached files ( I deliberatly deleted some informations specific to my pc )
Now that my only way to remove it is by your unlocker, do you think it will work ?
Again, the boot block recovery procedure doesn't work
Thanks in advanceAttached Files
