[Q] Help a noob make a safe upgrade...
New member, longtime lurker here. I have a I535 Verizon GS3, and am rooted. It has been quite a while since I did that, and I just wanted to make sure I knew what I was getting into before I tried to upgrade to a newer rom. The reason I want to upgrade is I currently have a Sony Smartwatch 2, that I love but I shattered the screen. In preparation to buy one of the new Android wearables, I need to be on a newer version of android as far as I can see.
Right now I am on: 4.1.2/ Baseband version, I535VRBMB1/ Kernel Version 3.031-86103/Build number JZO54K.I535VRBMB1
I am not sure what of that info is important so I posted it all. I don't remember the exact name of the rom I flashed before, but I think it was created by member Dalep, and it was something like "Stock Rooted". It was basically just a rooted version of the stock rom. My only reason for rooting was to use a wifi tethering app which has been working well for me. I was nervous with the initial rooting and flash process, so once I got what I needed I stopped working on it and used my phone as is until now. Now I would like some guidance on how to get my phone safely up to date.
1. I am running Clockwork Mod Recovery v126.96.36.199. Is this still usable or do I need to update it?
2. What rom would you all recommend for someone who wants a fairly stable phone and does not care so much about tinkering/customizing?
3. What does a nandroid backup do and what can I do with the backup (I did one before I installed this current rom)
4. What is the best way to get my phone back with the apps I have installed? (i.e. reinstall from Playstore, etc) I don't have many apps.
I am sure there will be more questions, but thank you for reading my long first post, I just want to make sure I am clear about my current state, skill level and intentions.
