first time on a forum based setting but glad to be here. I'm new to rooted phones so bare with me. Ok recently I rooted my phone and I succeeded yes. I was running mik rom 2.59 i think but the mirroring wasn't working so I decided to go back to 5.5 mik so doing that started my problem Ok now today for some odd reason I decided to to clear my phone and sd card without backing up my rom now when I boot my phone only the default back ground is showing I cant swipe down to access anything basically its just a background I need help restoring the original os or rom for my evo 4g. any assistance would be appreciated. Thanks guys in advance
