Please read, I need help!
(Sorry for the long paragraph, just read the bold parts)
So I've been using my LG Volt on Sprint for quite a while now. I'm a pretty heavy user of my phone, and most of the time, I root my phone just so I can have more power for my device. Even before I rooted it, though, it started acting up, like going really slow in the menus, freezing up and restarting, all that good stuff. Then it kinda just stopped booting up. It seemed like it was loading the OS, since when I plugged it in to charge when it was off, it still showed my percentage. But it wouldn't boot past the Sprint screen. I then found out I was in a bootloop, which I don't know how it happened because I hadn't really done anything to mess with the system files (as I said before, this happened before I rooted). I installed a fresh ZV4 Firmware (I couldn't find anything better) with the LG FlashTool and I noticed the Sprint bootup animation wasn't there, and there was a stock LG bootup instead. Also, none of the Sprint bloatware was on the phone. I disregarded it, thinking I could just activate it later, and installed everything I had before, except this time, I strayed away from apps that didn't come from the Play Store. I did end up rooting the phone, because the LG Volt is on Kitkat, and I couldn't really do anything with my SD card unless I rooted. It was working fine, but then the same bootloop problem happened again. I got pretty upset, but I knew how to remedy the problem from before so it was an easy fix. Still, the Sprint bootup wasn't there, but I didn't pay notice to it yet again. This same problem has been happening much more frequently as of late. In fact, as I'm typing this, I just fixed it again. I'm thinking it might be a problem with the .tot and .dll files I'm using on the FlashTool, but I couldn't find anything better. I did a malware scan on the phone storage and my SD Card, and nothing came up, so I'm pretty sure that's not the problem.
I really need help with these 2 problems (the frequent bootloops and the Sprint stuff not showing up), because every time the phone goes into a bootloop and I reset it, I lose everything I had on the phone! I hope someone can help me!
