I burned by mistake one of the chip...Marking code is 'QqFOB' and is just above BIOS chip in QFN16 package.
Do you guys have any idea what chip could it be to replace it ?
I did create a topic on stackexchange juts in case... https://electronics.stackexchange.co...own-qfn16-chip...

The one you sent doesn't work, exact same behavior: 2nd boot 'reset security settings to defaults' => asks for administrator password
As I'm aware you patched thoses VSS entries in MAIN:

• TheftRecoveryFlags
• BatteryCTNumber
• HP_MUD
• BuildID
• FactoryConfig

You also overwrite UserCred VSS entry by a clean one, and activate H.p.M.p.m by replacing the target bytes to 23 01 00 02.
You patched only NvramActiveRegn in EC as I saw.

If I dump again, EC has it's NvramActiveRegn with data again it's not filled with 0xFF anymore.
I noticed there is also an NvramActiveRegn...

You did also this post in 650G10 : https://www.badcaps.net/forum/troubl...39#post3689039
where it seems you provided clean BIOS for 630/640/650 G10 in v74 & v75 family ROM.
Here is BIOS locked 630G10 file in attachements.

I'm mostly looking for how you patched instead of the unlock result itself.
As I understood in your post above you used stock bios from customer. ME Region in configured (so UnInitialized on...

For my issue above I tried what mentionned by essaadi here:
https://www.badcaps.net/forum/troubl...44#post3738044

namely:
A) Replace "aa 55 3f" with "aa 55 3c" :

After : QP.o.w.e.r.C.o.n.t.r.o.l
After : QH.P._.R.u.n.t.i.m.e.B.B.C.h.e.c.k.P.o.l.i.c.y
After : f.f.l.i.n.e.U.n.i.q.u.e.I.D.E.K.P.u.b.C.R.C
After : QH.p.C.o.m.m.o.n.S.e.t.u.p...

As spider300 and Arsch wrote, after flash thanks to HpMPM I can access BIOS but when I hit at 2nd boot 'reset security settings to defaults' => asks for administrator password

I've done as rex98 says:
First boot press f10 apply factory defaults and restart
2nd boot reset security settings to defaults and exit

The exactly here '2nd boot reset security settings to defaults' where it asks for administrator password​.
hoaca388 do you have an idea maybe ?

HpMPm and UserCreds were patched (Even then patching didn't chaneg a thing it seems)...
