    All of the chips I have done thus far have been 3.3v. I haven't needed to adjust anything with the VCC (yet), but I also haven't done the 9470m. Share your photos and data!

    And getting a good read/write for for has been dependent on using the Pomona brand SOIC clips. Others were super spotty and inconsistent. The Pomona clips seems to be spot on every time.

    -Cheers

    I can confirm I was able to remove the BIOS password from a 9740m Ultrabook. I pulled the BIOS and saved to file. Using HxD and my pad file data to blank out the $VSS store area of the BIOS file, I saved the new BIOS and flashed it back. As expected, once powered on, the message of missing system data apeared, so I booted to WinPE and restored the data using windmifit without further issue.

    Hi, Mazzif,

    I need to remove the BIOS password for a HP EliteBook 840 G4. Is it possible to achieve this following the method you've described in post #29?

    Unfortunately, I don't have the knowledge to get this thing done :(

    I would appreciate your help on this, if possible.

    Thank you!

    The G1 and G2 were able to be, Id imagine the G4 (and G3) would be also. Get a Raspberry Pi and some wire kit and build out a flasher as I have described. At worst, you'll have fun with the project and be out a few $$. At best, you'll recover your laptop.

    If I come across a G4, Ill be sure to post the details.

    I have already purchased the following: Raspberry Pi 3 + Pomona test clip (model 5250 - SOIC-8) + m-m breadboard wires. But I made a mistake: I didn't pay attention to my BIOS chip package type and I recently discovered that it's a not a SOIC-8 chip, but a WSON-8 one (see the image attached).

    So I'm stuck again... and I don't know what can I do next... :(

    Use my padding file and write over the $VSS store area in your BIOS, save it and then flash that BIOS.

    I hit one of these packages recently as well. The WSON8 really mucks things up. I dont have a solution to that other than physically removing the package and replacing it with a SOIC package. Im still looking though.

    Hi Mazzif,

    I've been following your guide in (OP)#29 but I keep getting errors when I run wndmifit from within Win10PE (I created an x86 version).

    I'm curious what version of wndmifit you are using and where can I get it?

    I've tried wndmifit from NbDmiFit-2.07 and NdDmiFit-2.09 which I found on the internet, but both produce errors.



    Here are the errors I get:

    Running wndmifit from within Win10PE:

    BIOS Setting could not be read. BIOSConfigUtility.exe may be missing or invalid

    Running wndmifit64 from within Win10PE:

    This version of X:\windows\wndmifit\wndmifit64.exe is not compatible with the version of windows you're running. Check your
    computer's system information and then contact the software publisher.

    Any help would be great.

    Thank you

    "BIOSConfigUtility.exe may be missing or invalid"
    Is BIOSConfigUtility.exe in your wndmifit directory?

    "This version of X:\windows\wndmifit\wndmifit64.exe is not compatible"
    Looks like your running a 64bit app in a 32bit build of WinPE


    I built my Win10PE from 1Win10_1607_English_x64.iso (Codename Redstone?)
    Version 10.0.14393.0
    64bit

    Im running NBDMIFIT v2.0A with wndmifit v1.0.1.4 (September 1st, 2015)

    wndmifit.exe and wndmifit64.exe both work fine in this environment.


    I dont believe I compiled with any additional drivers.

    For some reason wndmifit could not write the model number on a HP 8470p, so i ended up with another error on startup screen. Tomorrow i will unsolder the chip again ( i haven't any clips) and reflash it. Hopefuly it works this time. Again, Mazzif, you are the man!
