Yeah, Hard-SPL is all you need to flash a custom ROM. There's a SIM Unlocker too, but you won't really need that if [edit: what he said...].

FYI, make sure your using the correct H-SPL...depends on your phone, Sprint, Verizon, etc. Just double-check you're doing the right one, cuz you don't wanna brick yer TP2!
