Hello to all, or recently bought a samsung i6280 galaxy core. Today fleshato or the monster build 3, and everything went well, apart from anything else, but not part of the 3g and gives me no service, or even changed the modem but everything remains the same. The phone was branded 3, I do not know if this compromises anything, however, remains the fact that I can not run any roms, all with the same problem. Someone can help? (sorry for my bad English, I'm Italian)
