ok. on that screen it should say SPL-0.37. CMONEX if your phone is unlocked. If it doesn't say that you haven't unlocked it correctly so you need to try that again. If it is unlocked and you are getting that error, I would make sure you downloaded the TP version of a ROM not the diamond version. If you have the right version, make sure that the ROM downloaded completely without errors, sometimes it may appear it downloaded but it was not complete.
