Problem going back to original ROM
I've done some experimentation with custom ROMs but now I would like to return to my original ROM.
I have a CID-locked G4 and this file RUU_Prodigy_2170702_21707102_20710_QTEK_WWE_Ship.e xe which I thought would return my Wizard back to its original state. However when I try to do the update it aborts with an error, which I think is due to the fact that the ID of the current ROM (or something else) is not the one expected...
I noticed that some custom ROMs have a special noID RUU. Can I simple use this with the official nk.nbf?
I also noticed that the official nk.nbf contains IPL/SPL. Will this brick my device?
