My brother got a new LG optimus M today from metro pcs... I have the Ascend from metro, and he liked that I rooted my phone and stuff and asked me to root his as well... Was having a little bit of trouble at first since the LG doesn't have a file manager already on the phone like the ascend does... So I downloaded it from the app store no problem, then I used gingerbreak to root the phone and then installed titanium back up and deleted the metro apps that weren't needed... then I went to download apps for him in the app store and process.android thing keep popping up and said force close... I got frustrated and just rest the phone (thinking it would put everything back from how he got it), and now I can't download anything at all from the app store(keep getting the same force close message), don't have a web browser and have no way to put the file manager or anything on there to try and at least unroot the phone, I don't know what I did!!! I saw a few threads on here with people who had the same problem but I don't understand what to do, I really need help step by step. PLEASE!?
