Yes i have a Samsung Galaxy Grand Prime SM-S920L and one day it just went freakin bonkers. Apps started crashing, rebooting itself over and over, then it would only boot into recovery mode and now it wont boot at ALL. No sign of charging when plugged in nor can i boot it in download mode. When plugged into a PC the pc chimes and in device manager it comes up as QUALCOMM HS-USB QDLoader 9008 (COM3). This phones software has never been tampered with. My grandmother had it if that says something. No root. Is this phone fixable or not. If its something i can do like reflashing (which i tried to no results) or anything of that sort i can do it. A hardware which i'd like to know than of course no i can. Plz help or advice.
