Hi; I have a Samsung Galaxy Discover for Cricket (SCH-R740C) that gets stuck on a black screen(after the boot logo) when trying to turn it on. I have tried leaving the battery out for 8min, doing a factory rest multiple times(along with wiping cache) in recovery, and leaving it at the black screen to see if anything changes, but nothing does. I can still boot to Download Mode and Recovery. It is rooted but I did not do anything to modify the system(expert for using adaway to remove ads and freezing some apps). Is there anyway to recovery it??
