I installed the Blazer Phantom Rom today on my GS3 (Sprint). I have used CM before on all my previous devices (MyTouch 4G, Evo, Galaxy S2) and have had bad experiences using other ROMs. (Bricked MyTouch and Epic 4G). I completed the install, but my device doesn't give any indication that the flash worked correctly (in about phone). There are clearly modifications done (Beats Audio) but nothing in the system that says that I was correctly done. Usually CM says in about phone that I am using whatever version
