[Q] Upgrading my S4 still running 4.2.2 while keeping root
Hi everyone! I need some help updating my S4. I rooted it awhile back and I'm very much of the mindset of "if it ain't broke, don't fix it," so since it was doing everything I wanted, I've just left it alone and kept dismissing the prompt to install the OTA update. Now I'm having some issues and want some features of the newer versions of Android, so I was looking around for the best way to update it while keeping my root access. All the guides I can find, however, talk about upgrading from 4.3 to 4.4 or 4.2 to 4.3. So I was wondering...
1. What version should I update to? On my last phone, a Droid Bionic, one of the big Android version updates ran so horribly on it that I ended up getting a new phone. Because of that, I'm very nervous about updating my phone and having the performance suffer.
2. There must be a way to go straight from 4.2.2 to whatever version I choose, right? Do I need to go dig up some old guides on how to update my phone so that the most recent guides are relevant?
I hope I'm not being a super noob about this. I tried Googling around, and I'm pretty tech savvy but just haven't had the time to keep up with recent developments, so some guidance would be very helpful!
About my phone:
Verizon Galaxy S4
Model #: SCH-I545
Android version: 4.2.2
Baseband version: I545VRUDMI1
Thanks so much!
