Re: HP 840 G7 password

RCUnlocker did unlock the 16MB here locally, but if it didn't work, test the 32MB. First time I do this. Maybe start with flashing 32MB only.

Re: HP 840 G7 password

Translates as function byte, so probably password is still there. Sorry the method didn't work, applied one that is for 840 G8.

HELP MY G7 840 G7 Password SWAT problem

Re: HP 840 G7 password

If you are willing to try, unlock the 16MB file with RCUnlocker, and if it doesn't, continue with the BIG CHIP_unlocked. Please report back. Make sure you have good backups before any flashing is done.
This is how hoaca388 solved it:
"You used the bios of another machine, so in the 32MB bios file, there is MPM information of that device and it has enabled the "security endpoint". I rebuilt the new 32MB bios file, cleaned the ME region.
With the 16MB file, I deleted the first NvramActiveRegn region.
But now you may have trouble with MPM again."
No trouble with MPM was reported, but further work may be needed, perhaps also cleaning ME Region on the 32MB chip. I only cleaned the USER CRED Region.

Re: HP 840 G7 password

Your backup should always work. Resolder if chip was taken out. If it is a WSON, I usually take it out, clean underside of chip, clean and tin again all pads, with very little solder, lots of flux and hot air station a little bit higher temp setting, faster time. I have had WSON chips that somehow are soldered on one corner but the opposite corner diagonally is lifted, probably due to too much solder in the middle pad. Using a digital microscope helps seeing that tiny detail.
