So I just got my STU and it was working completely fine, for a day...... I customized it, I put the apps I needed on it, and I was all set. The next day it just shuts itself off. I try to turn it back on and it showed the white Samsung logo. Then it shut off. Then it showed the logo. Then it shut off. It just keep repeating. I said WTF and I did a battery pull. It did the same thing. It wouldn't even let me hard reset it. But, it will go into download mode. I tried plugging it into my computer. Looped. I tried a different battery. Looped. I tried a different charger. STILL LOOPED. Well, it's pretty obvious that I need help. I'm extremely new to this by the way. Is there a solution or should I just make this a $220 paper weight?
