    Re: HP BIOS unlock tool

    Hi,

    Good news, @RethoricalCheese, your unlocker work wonderfully !!
    The clip of the ch341a was atrocious but I did manage to read twice and write without errors at the end
    So yeah, I can confirm for the others that the hp Z440 with a Winbond 25Q128FVSQ can have is bios password removed

    Many thanks

      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!

          Also I am trying to use pogo-pins and 3D printed fixture to read and program wson8 chips. If anybody has a nice design for that, please do let me know.
          Did you succeed in finding a 3d model for printing a case for wson8 chips? If not I will purchase one and copy the design and share the STL model with the forum. Feel free to share adapters that has a good reputation so we can copy something that likely will work

            Yeah, atrocious is the correct definition. Especially if the chip is wson8

              as for the software I'll have a look at mine tonight after work and give you a link to where I got my software which works perfectly.
              Please feel free to share the link to the 8 pin jig you bought from ebay.

                I tried to 3d print pogo pin holder but couldn't get it to work properly. It has been easier to just unsolder the chip and place it in the jig.

                  Re: HP BIOS unlock tool

                  Yeah, I can imagine it might be tricky. I guess so too, relatively easiest way is to unsolder and place it in the jig.

                        You can give DMMP BIOS (HP ProBook 450 G7 BIOS S71 dump).

                        On the first and on the second BIOS.

                        Thanks!
