Not in mod world… what did you expected? No one here or any other forum can remotely assure you of a NO risk operation, flashing modified files, even worst when its branded machines… an HP and latest security/signatures implemented.
Don’t have experience and don’t know ho to recover, don’t proceed.
EDIT:
@68k-dude
What tools??? Didn’t the user said it has no experience on this actions, please don’t encourage this, he’ll get a death system.
Can you assure him of a NO RISK operation???
Anyway, its his asset so his decision.
