I have an android ice cream sandwich. Last night before i went to bed my phone was fully charged but when i woke up this morning it was off. when i turned it on it only showed a black screen. i didnt know how to fix it. i dont know what i did but some how i got to android recovery system and now im stuck there. i tried pushing the reboot option but it keeps sending me back there and i also tried taking the battery out but it still doesnt work. what do i do?
