I have a samsung S2 I9100P bought aprox. 3-4 months ago and i've tried to unroot it, unfurtunately without success. In the same time it ran out of battery and it doesn't charge. The battery icon appears and disappears and after some minutes nothing happens, it's off. The battery appears and disappears only when connected for charging. Please tell if there is a solution and which is that, or should i through it away? Yhanks in advance for the answers, Have a nice day!
