I flashed the fission roms onto my phone and I currently have third eye black theme running. However I want to try out the different themes so i tried to install blackout preview and fission black edition, but when i press install nothing happens! I tried rebooting, but nothing is working. I have the bought version of launcher pro running if that makes a difference. Edit: actually I cannot install anything from the fission rom manager. Shud I try deleting fission rom off sd card nd copying it back on? Idk what to do.
