BTW, i tried the rex98's way but without any luck.

finally, it worked just fine, only with battery and adapter plugged in ( both ) .
Thanks rex98 and SMDflea.

And how about DMI ? i can't use HP DMI TOOL, not working in my laptop ( win11 ). the dot net program is not installing, any idea on this problem ?

I noticed there's a lot of unlock request for this model HP ELITEBOOK 645,655 14 inch G10
The patch won't work if the bios version is latest. use this bin flash both it won't work if you only flash the main you should Flash Both.
first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
use BCU and put your original DMI.
frequently asked questions:
can i use this to my HP ELITEBOOK 645,655 14 inch G10- yes

This is only for BID V77 only if you have different BID it won't work.

YES!!! It worked!

rex98 - you are a genius!

rex98 SMDFlea volinakis and osman68i - Guys, thank you so so much for all your help, you have no idea how much your help means to me.. thank you! I am now off to study and compare the files so I can try and learn to do this too!

Thanks SMDFlea, really apprecaite your efforts. These did not work either.. laptop booted and bios reported "Hp SureStart Detected an unauthrised change in secure boot keys" then "There is a problem with the end point security controller". I went into the BiOS and still reset all to factory, but MPM is still not enabled.

"laptop booted and bios reported "Hp SureStart Detected an unauthrised change in secure boot keys" then "There is a problem with the end point security controller". I went into the BiOS and still reset all to factory, but MPM is still not enabled."
So let me understand: you were able to enter in bios setup and checked in Security if there's no password?

[SMDFlea]

Thank you SMDFlea - Unfortunatley that did not work either. This time though it did run a bios update, but then returned with "Hp SureStart Detected an unauthrised change in secure boot keys" then "There is a problem with the end point security controller" again, and MDM is not enabled. Try manually enabling again via BiosConfigUtility and it still returns an "access denied" error when trying to write back the MDM enable flag.

Anything else you can think of please?

A new main bios to try. If it boots press F10 reset defaults, reboot reset security. Use your original EC_Bios

[hpboy]

flash the original EC_bios and the main bios i posted, see what happens then

I am at a loos, do you have any other ideas? The files that rex98 created here (https://www.badcaps.net/forum/troubl...s-needed/page4) for the 440 G10 worked fine on the 440 G10.

Do you know if there is a way to create a "clean" version of the files for this HP 645 G10 in a similar way to the rex98 files?

Really do appreacite your help..

Thank you my friend - unfortunately that did not work. On boot "a mismatch in security - restoring" error was shown and it rebooted into the same original state. Do you have any other ideas please?

Elitebook 645 G10 - Serial number change

I have an Elitebook 645 G10 which has has a replacement motherboard. The problem is I cannot update the serial number and DMI data by using all the usual methods - each time I try NdBMFit it reports that either the version does not work with the plaftorm, or is editing mode is locked and I cannot unlock it.

if I post the dump here, can someone help me to enable editing mode so I can update the serial numbers? Unfortunalty the "new" motherboard is linked to a company so during windows setup I am pushed to a company to signin (even if I bypass this and get into windows WnDMIFit will not run as the "platform is not supported".

Any help will by much apprciated. thank you
