    BIOS Unlock for HP zbook studio x360 g5

    Hi,

    I've been working on this for about a week. I've read the threads and ordered and attempted to use a programmer to pull the BIOS dump from the laptop with no luck. I tried using RcUnlocker, but keep getting a dll error even after reinstalling the C++ Redistributable. I also tried NeoUnlocker and another program. None would pull up the chip.

    That leaves me asking for help unlocking this BIOS. The laptop boots up to the Domain login with no issue. I can pull up the boot menu. Any attempt to open the BIOS or the BIOS upgrade menu is met with a password request. Getting the password wrong three times just leaves me with a message to reboot the computer and I'm back to square one.

    Model: HP Zbook Studio x360 G5
    System BIOS: Q71 Ver 01.10.00
    Serial Number: SCD9272118
    SKU Number: 6FP02UT#ABA
    System Board ID: 844F
    System Board CT Number: PHVKK048JCH01P

    Thanks in advance!

    remove the bios chip from the motherboard before reading or writing, or solder wires between the programmer and the chip.


    you need an SPI programmer..here is a video as an example...https://www.youtube.com/watch?v=DWWigscuQDY

      Took me a bit, but I finally figured out the problem with the 341 and it worked with no apparent problems. I managed to download the attached file.

      Relevant PC info in the first post.

        After posting, I examined the dump file i uploaded above and four more that i made with ASProgrammer. I also uploaded them to a couple online hex editors. They showed all RR's. All of the dumps passed verification with the same checksum. Is it possible that the bios has been cleared and simply needs a new bios version uploaded? The system is bootable and I am, in fact, installing Win 11 to it as i type this . . .

        Could I just upload one of the other BIN files I've seen on the forum to it to unlock it?

          Going through the few posts that have been made regarding this model. Here are the BIN files from the EC and TR Bios chips. I have tried them all on RCUnlocker and for these two files they say that they don't contain any information to unlock. The main BIOS file above got an error that it was the wrong size.
