You need to also use the certificate..install the cert and serial Can you dump ACPI with rweverything for me now you have flashed??
Put the certificate at the root (C: drive) and name it HP.xrm-ms run from command prompt: (Be sure to open a command prompt as admin) slmgr -ilc C:\HP.xrm-ms wait for confirmation and restart. You should not enter the certificate in the tool when modding for future reference...only the SLIC.BIN
