Error on changing keys in registry to unlock phone
 

I'm using regeditSTG to try to change these keys to unlock the phone:

HKEY_LOCAL_MACHINE\Security\Policies\Policies\0000 1001 = 2
-> Change the value data from 2 to 1

HKEY_LOCAL_MACHINE\Security\Policies\Policies\0000 1005 = 16
-> Change the value data from 16 to 40

I get this error:
"Error - Unable to perform this operation"

Does anyone have any tips/tricks/info on this?

try using phm regedit
