I've had my T-Mobile Samsung Galaxy S2 since about December of 2011. Today I had it randomly restart on me while I was at work. That's happened to me before but today I have a unique situation. The phone is stuck in a continuous cycle of restarting. It shows the Samsung logo, then the T-Mobile 4G splash screen and then back to the start again. That's all it does. I thought I'd try loading the stock ROM through Samsung Kies. The thing is... I can get the phone into download mode but it doesn't stay there unfortunately. It simply keeps restarting. The device was rooted but was running the latest stock T-Mobile ROM at the time. I did a wipe via recovery mode when I managed to get in there but... I'm not sure what else to try. I'd appreciate any insight anyone might have.
