Samsung Galaxy Prevail 2 Model M480 Got the phone from a coworker. Tried Factory Resetting the phone via Setting Menu, at least five times, however it didn't work. Couldn't wipe the phone's user data or anything. Even tried taking the battery out and re-inserting it. Still didn't wipe the previous users data or setting. Finally Master Reset the device via Recovery Mode/Menu. After Resetting it, I rebooted the phone via Recovery Mode. Thinking that I successfully wiped everything and had the phone back it the original Factory Settings, I turned the phone on only to find out that the phone wouldn't come one (via pwer button.) After unsuccessfully taking out the battery again and re-inserting it, it still didn't work. Device used to only turn on in Recovery Mode. Now, it won't even turn on anymore. When it's plugged into a charger, the Samsung logo appears and then re-appears. Don't know what to do.. Please help...! I bought the dude lunch and paid $80 for the phone.
