Re: HP 450 G2 (m74) unlock

Well did used the rcunlocker, and the mpm is unlocked, but after unlock there is a not in commited state message,

even after use the hp dmi tool, and lock the bios again after checked for the right numbers, it keeps appaering on the screen.

someone any idea how to remove that warning?

The bios from your furst post is not password locked, so RCUnlocker has nothing to do (i.e. to unlock) with this dump, in this regard your second post is ... well a little strange for me, "not in commited state message" could be related in most cases with the missing DMI information, or if the ME firmware has been messed with. Since you didn't come up with some information and/or history of the problem (as usual) try to clean ME firmware first.

sorry was totally wrong with the topic. i think i had a bad day haha, but the mpm was allready unlocked, the only problem was the not in commited state warning. even after filling the serial nr, sku, ct, build id and feature byte in nbdmitool en commited the warning keeps appaering on the screen

Edit: thanks for the _NEW file, but that one isnt doing anything, laptop turns on and screen stays black

Are you sure you've programmed the bios chip correctly, i.e. using verification option (and reading the chip once again to compare) after that to be sure the content of the chip matches the bin file? Also are you sure the chip is soldered to the board (if you doesn't use clamp or wires and so on to read/write the bios chip of course) correctly?

Yes im sure it is programmed correctly, i use wired clamps, and the chip is readable correctly, tryed 2 times, and both times black screen, when i flash the original file back, than it boots.

OK what is the cpu (and gpu) in your machine, and where is your factory dump? If you have it, post it too even if it's bad/corrupted.

sadly, dont have a factory backup, but the cpu is core i3-4010 and gpu is intel graphics

In this case you must use M73 bios, M74 is for Broadwel based mashines.
Try this confirmed good bios:

Edit: Or rather the opposite, as far as I can see now the M73 uses a newer version of the ME than the M74 (usual HP mess - contrary to any logic the lower number bios version is for the newer generation), so M74 must be the right one for you. You can try this (M74) dump:

Re: HP 450 G2 (m74) unlock

exactly, the m73 version gives me a screen broadwell platform not supported,
and will try the one from peste tomorrow

Re: HP 450 G2 (m74) unlock

the version from peste works oke, but has 15-20 sec before the screen goes on

Edit: when i do a Clean Me with Intel Easy Clean Me, it starts like it should, fast instead of 20 seconds, but with not in commited state

Re: HP 450 G2 (m74) unlock

Edit 2: nevermind, added the wrong version of clean me, after i do the advised version, it works like a charm ,
