Hi, I need some help. So I have had my Samsung tab 4 since 2014 and It has worked fine since this last half year but was still useable to its fullest extent. it started to start dying quickly and charging very slowly which was an issue but not to serious ( I think it needs a new battery) So my tablet died the other night and when I plugged it in it was stuck on the Samsung logo because when I know its starting up it will go to starting or optimizing applications or something like that but it was stuck which I thought was no problem I had this happen before right so I just restarted it because normally that will work but it didn't so I went into recovery mode and wiped cache and wiped data and did a complete factory reset in hoping that this would work because it was said it would it got past the stuck Samsung screen and went to optimizing apps and now my problem is while it is doing that it quickly goes to a screen that says unfortunately phone has stopped working and then says an app called KnoxMigrationAgent app has stopped working after I press ok and it keeps switching back and forth but the problem is I can't do ANYTHING! I can't get into settings like for example I can control notification volume but when I hit the gear I can't switch it to media volume literally the only thing I can access is just factory mode if I shut it off. so is there a fix or fixes for this or is my tab 4 completely pooched?
