Hi there, this will be my 1st time trying to perform this. Can I know prior to do a backup, where is the location of the stock TW? And how do I do a backup for this TW? Sorry guys I'm really a noobies.
Well there's lots of ways to backup TouchWiz. Simplest would be just to go into /system/priv-app in your root file explorer and find the TouchWiz folder and just copy(not move) it to somewhere like your Downloads folder for safe keeping. Then you can just copy it back later and replace it with the new one if you want. You can also back it up with an app like Titanium Backup and restore it through there. To be absolutely safe though, I recommend always backing up all your system, data, etc. in TWRP just before installing the new Touchwiz(or anything to do with the system for that matter). Then if you want to restore you can just do a quick wipe and restore everything back to the way it was.
All of this is only if you think you might want to go back to the old version though. Personally, I like the new one better, as it's quicker, cleaner and has more intuitive features. There's no risk of running into any major problems in the system or anything. Either it installs or it doesn't and even if it does it really just works like an app update.
