[AC Question]

A tech savvy person wiped Touchwiz off of my phone and put CyanogenMod on for me, I kept getting notifications that I needed to update it, so I took matters into my own hands and used android forums as guidance to put CyanogenMod 10.2.0 onto my Samsung Galaxy s3. It worked OK like that for a while but with a few glitches. Then suddenly it stopped turning on at all and just runs the CyanogenMod start up on repeat.

Obviously I can still get onto ClockworkMod Recovery mode, so I was thinking of putting Touchwiz back on, but I don't know how and I can't seem to find any guidance that's particularly easy to understand (I don't know a lot about this stuff, and I'm no longer in touch with aforementioned 'tech savvy person'). I was hoping it would be a case of downloading the software onto the sdcard via my computer and then installing it through ClockwordMod, which is what I did last time, but it doesn't seem to be as simple as that this time!

Please help!
