My Galaxy s4 is from Sprint/ModelNumber:SPHL720, for a month now i have been trying to download the new 4.3 update and it keeps Erroring when its installing. It downloads fine but when it reboots and the little android app shows up it falls down and has a red error sign on it. Idk whats going on, i unrooted my phone and i asked sprint and they said just to wait.... ive been waiting.... and to get the update back all i have to do is clear cache and i can download the 4.3 update again but it will keep erroring all the time... helppp!!!
