Re: HP BIOS unlock tool

Hi! Need help, I have an Elitebook 1040 G3. Unsoldered the BIOS-chip (W25Q64FV), attached it to CH341, did 3 dumps that were zero differences, continued to RCunlocker, did not work ("Missing unlockable content", the HPunlocker did produce a "_unlocked" file, erased the W25Q64FV and flashed "_unlocked".

However, now when i read the chip again and compare it to the unlocked version, I get 1500 differences? And I also get "Verification error on address: 0000000F" in AsProgrammer 2.0.2. Don't know what to do!!!

Can someone have a look at my files and see if something is off? thanks!

Re: HP BIOS unlock tool

That error message was a huge hint to you. You are trying to modify the wrong chip...

Re: HP BIOS unlock tool

Hello RethoricalCheese! Thanks for your great tool! It might help me accessing my HP Revolve810 bios again! As a big idiot I did not write down my pwd so I can't access Bios setup anymore ;-( If I understand well, I need a file to use your HPunlocker.exe
The trouble is I don't know where to get that file ;-( Do I need to unsolder the BIOS chip first???
Thanks for your help and understanding!

Re: HP BIOS unlock tool

From your bios chip. You need a programmer for that.

Re: HP BIOS unlock tool

Can anybody help me out here? I m trying to unlock an HP 820 G3, tried for several days no luck so far, I have tried different programmers, whenever I flash the original BIOS file the system boots up but the password is still there, when I flash the unlocked bin file, it either wont respond or will flash yellow and orange indicators then go full fan spin, I also tried to recovery bios by USB with official HP rescue tool, no luck either. I will attach both original bin and modified bin below, could anyone knowledgeable take a look please and guide me in the correct direction, I have an CH341a black minprogrammer, I mainly use NeoProgrammer, seems to be most stable among the bunch I tried.

Someone guide me in the right direction.

Re: HP BIOS unlock tool

thanks, I finally solved it. I used RCUnlocker, erased the EEPROM wrote the file then verifiedit, at first I thought nothinf had changed. I did a few power cycles, inserted a USB with rescue BIOS first it didnt work then I put it in a different port while powercycling, now iy works perfectly fine, thanks for the help.

Re: HP BIOS unlock tool for ZBook G3

Hello guys!

I have a ZBook 17 G3 laptop with Power-On password set - password that I don't know for I've never used it (nor set it explicitly). I've been using my unit for years now, unlocking it with my fingerprint, until new fingerprint driver reinitialized something and removed my fingerprint (and left me with a power-on password I never used nor intended to - HP Client Security tool I used to register my fingerprint for power-on auth also associated windows password with it).
I know main BIOS (admin) password, but it's of no use for I can't get into BIOS...

Anyway, my unit has Winbond 25Q128FVSQ chip, mentioned on a few pages in this thread:

1. This one shows use case I could use (before unfortunate fingerprint removal, there was Bios Administrator user option on power-on authentication screen)
2. This one is for very similar laptop, though I don't know what was the problem with it...

Before I try it out, I'd rather ask first, could this unlocker tool help me with the problem I have? These two posts made me think so, but I'd better play it safe... I don't expect any guarantees (would be silly to do so), rather an advice or a guide. Thank you!

Just got CH341 thingy with the clip (8 pin), disconnected main and CMOS batteries, made sure I properly connected everything and tried to read the chip, but without success. Managed to make it worse then it was - now I get 5 led blinks on boot... Any clues - messed up bios chip or the motherboard? Thanks

Re: HP BIOS unlock tool

Big thanks to everyone here for their great posts.
I have a HP640g1 which was bios locked with a forgotten password from a couple of years ago. Followed the instruction from post 1. All good now.
Did run into a few problems but that was user error (Myself).
Laptop now with unlocked bios.
I have now experimented with both unsoldering the bios chip and using the SOIC clip method.
My problems encounted was poor resoldering of the chip back which looked good under a magnifying glass but was bad as all i got was a black screen, power button permantly lit and flashing yellow charging light. After removal and resoldering this problem was resolved and i could see pin 8 bent previously not making a good contact.
The clip method also works but i had to ensure good contact was maintained during write as advised in other posts by checking and verifying the bios.

Thanks
