So, being the dumb idiot i was, i was having issues with my system and decided to use twrp and accidentaly wiped the system partition. Now i have no OS, and no backup of the OS. So am i screwed? EDIT: I managed to get the system back on, but it is under a different carrier. I am trying to flash a .kdz to get back to the correct carrier, but the flashing programs keeps saying "problem with communication between cell phone and pc"
