I was on Omni Rom 4.4.2. today I downloaded CM Nightly 10.2. Placed it on the SD card..rebooted into recovery. Wiped data, cache everything and then ran the CM ROM file to install from zip.I got a warning that said installation failed. Now i don't have any ROM as i did a full wipe. When i try to mount USB storage..nothing happens. I have TeamWIn recovery. I don't knwo what to do now. Please help.
