I have the 32 GB Sprint Galaxy Note 3 with an 8 GB microSD. It's rooted using Chainfire's method. I also have TWRP for a recovery, but I'm using the stock Sprint ROM that came with it. I have a few root apps installed (Titanium backup, AdAway & Root Explorer) but the rest are what Sprint (& Android) put in there, minus a few that are totally unnecessary for me...(chat apps, picture drawings, step counting & so on) that were removed with Titanuim. It's still on 4.3 Jellybean with PUBMJ4 baseband. I also have the Wi-Fi hotspot fixed through 2 file replacements using Root Explorer.
Now that you know what I have, onto the question...
I see many, many ROMs in other threads that I'd like to try out, but don't know how to go about doing this. Before you jump right in & answer, here's my problem. If I try a ROM but don't like it, or it doesn't suit my needs, how can I go about going back to what I have now in the best (& fewest) steps necessary? In other words, to go back to exactly what ROM I have now, the apps installed, baseband, the whole nine yards. Just like a computer backup, it's a bit-for-bit restore, completely mirroring the hard drive. Understand?
Maybe you could explain to me like I'm seven years old what apps I need, what procedures are taken, the order in which they happen & so on. If I need an app or two to do just this, I have approximately $20 Google Play credit left.
Can a DEV or an experienced person that's done just this help a fellow out? Don't get me wrong, the stock ROM I'm using works for me, but there's ROMs posted that look just awesome! It's all about "personalization", am I right?
