http://forum.xda-developers.com – I tried following some videos by QBKing77 and some other advice I found on threads here but am stuck and don't want to go any further in case I mess something up. So far I have flashed back to a rooted EL26, installed CWM5.0.2.7, wiped everything, and tried installing the latest stable CM9 ROM. When I go to flash the CM9 ROM, here's what I get: assert failed: getprop....Installation aborted. I have attached a screenshot. Please help! Naked without a phone! Attached Thumbnails   (HowTos)
