So I have CyanogenMod 10.1 right now on my phone. I want to try out another ROM like AOKP but then I want to switch back to CM. Do I just backup my CM, flash AOKP, then gapps? I don't know when to wipe the cache too. Please help.
Boot into CWM recovery, make a backup, flash AOKP and GApps, wipe the cache, and reboot. Then, when you want CM back, just reboot into recovery and restore the backup.
