HI, this question is for the SGH-T989 specific, so some of the other answers I saw for other devices didn't really help me..

I recently just Rooted my phone!! Yay...I know, it's about time...Well, I'm trying to understand this stuff as I go about this journey...Basically I bought this phone once it came out..(Oct. 2011) I had the original Gingerbread 2.3.6 on it.. periodically getting the updates and installing them till I was on the ICS 4.0? whatever one came out in Aug-Sept 2012. With that said, I had some issues and wanted to go backwards, which I did successfully using ODIN..that's where I stayed for the last 5 months or so....

I actually had a hard time trying to get the super user 3.0.7 installed, so I had to use an older CWM (recovery-cmw-hercules.tar) which allowed me to install the SU...

I guess I needed to be on ICS in order for the latest one's to work. I now want to install ICS (the latest one) in order to try out some ROM's and was wondering:

1. Once I upgrade to ICS from GB, will I have to Root all over again?
2. Will my Nandroid back up still work if I restore it from back up in the Recovery Area? reinstalling all my apps and data for apps?
3. I'm using Titanium Back up too, so does this mean, that once I Nandroid back up, I can wipe it as many times as I want, I can just restore all my stuff using the Nandroid back up/ Restore?


I was going to use the last 2 of the followling: ClockworkMod Recovery 6.0.2.7 or ClockworkMod Touch Recovery 6.0.2.7 or TWRP Touch Recovery 2.4.1.0 again, as I tried them before, the Super User didn't work..But understand that these 2 will, when I update...

Basically, I don't want to loose all my Data and apps, but if I need to back them up, I will, just in case...

You'll be able to keep your data if updating from Kies. I don't know if your root will stick, but it's a simple task to reroot it.

1. I'm 99% sure u will lose root. BUT that's my opinion and you need the fact so wait till someone else answers. However I don't see the harm in re-rooting. As stated before - quite simple.

2. No if u restore a nandroid back up u would undo ur progress and go back to gingerbread - the exact state in which you created the backup.

3. If you are using Titanium and all u need backed up is ur apps and data then ur set. Doing a nandroid backup is just a safety net in case ur update to ICS goes wrong. If your update goes well then that backup is now useless. If it goes wrong then u restore your backup to gingerbread and try the whole process again. So in summary - Nandroid for system backup , Titanium for apps and data. Also, as long as you don't wipe ur internal storage or SD card u will always have ur titanium back ups saved and therefore can wipe in recovery as much as u want since it only effects the system partition.

I see your confusion lies in differentiating between a nandroid backup and apps/data backup and what each one is for. Hope I cleared it up. Good luck

Yes!! Thanks!! You cleared up a lot of questions I had. I also answered some of my own by just doing things with trial and error, but you also answered and cleared things up for me...Thanks!!!
