[Q] Unrooting or updating
Hi, almost a year ago shortly after I got my S4 I was very eager to root it, so I came here and followed the guides. I successfully flashed the ROM and proceeded to root my phone but still didn't fully understand the process. I've been sitting on the same version of Android (4.2.2) for a while now and cannot update because there was a file I had to back up and rename. This file was the file which launched the updater, and wasn't part of the guide...
Just now I decrypted my phone, re-flashed it with TWRP, did a factory reset and still have a rooted phone with no update file. I fear the risk of bricking it if I proceed with adding ROM's. Is there an easy way to either update my phone, or unroot it? I may have naively made the only backup image the one that was rooted and with no update file. Staying rooted and updating would be prefered but I just have no idea what I'm doing, to be honest
-Take care, Rob
