I installed unnamed rom on my gs2 two nights ago. Yesterday I finally went to charge the phone and for whatever reason it was not charging. I tried to reflash the stock rom that i backed up before installing the unnamed rom but i guess i did it wrong or it didnt work. all I managed to do was wipe my phone and that just wiped the unnamed rom and now im left with nothing. I want to go back to my stock rom how do I do it!?
