    Re: RCUnlocker

    I still have not seen so new machines but I would say option 3. Modify 32MB EC bios, not main.

    The error you get on unlocking older models like 8470p just gives an error from trying to display machine information. It will modify and make an unlocked file before it gets to that error so it's okay to ignore it.

    Tested this software on hundreds of machines before releasing but it still wasn't enough But looks like there's just 2 main problems and one was made to stop people from modifying wrong bios chips on newer HP models.
    RC:
    Regarding ZBook 14 G7 and G8 where both BIOS chips are 32MB
    Do you have any guidance on how to clear the PW?
    There doesn't seem to be any unlocker tool or any documentation
    on how to Edit or clear the BIOS PW on these machines?
    It appears that there are two methods used on this site to "skin the cat":
    1. Using both BIOS 32MB dumps
    2. Using just the Main 32MB Bios Dump where you don't have to remove the entire board which saves time.
    Do you recommend #1 or #2?
    Thanks!

    You must make a backup of the bios chip using an SPI bios programmer, see: https://www.badcaps.net/forum/showthread.php?t=103526

    So, Cheese, does that means that even if I try a model, which your app keeps telling me "Wrong chip. Try reading and unlocking 16MB chip!" I could just go ahead and process the 16MB one? ..Great app! BTW.

    The thing about me is that I always been getting the whole content of the HP on the 32MB .bin file, not on the 16MB one. I mean, the: "Product Name, S/N, SKU #, Build ID, Feature Byte, System Board CT Number, MAC Address, etc."

    Works.

    (I always make a backup of BIOS bin file).

    I was very confused by that error - in computers errors are errors. But in spite of the RCUnlocker error, the BIOS password was gone, and an another lesson was learned. Thank for support.

    OK backup flashed to 32mb chip and unlocked the 16mb one! We are back up and running.

    Gotta be the coolest thing I've done since the Xbox 360 "kamikaze hack" to reflash their disc drives!

    Re: RCUnlocker

    Well unit refused to boot just black screen and fan full speed, ill desolder the bios chip and reflash it tomorrow.

    Hp elite book 850 G5
    I used flashrom on a raspberry pi w to backup and flash but I had to export the "bios_region" from the file using "Uefi Tool" to get the RCUnlocker to read it. Would not read the full bin without throwing an error otherwise. I then remerged the bin and flashed it.

    This is incredibly fascinating. I was trying to find the bios portion needed from the factory bin and couldn't figure it out. This guy just makes a tool doing it in one step with Bios_region. ��

    I'd still like to know where in the new bios you can find the part needed to unlock a locked bin.
