My phone has been rooted for over 2 years now and I’ve run a handful of ROMs, with Hyperdrive probably the most stable of the lot. Last fall I was losing some functionality (bad microphone) and I figured I might as well try a new ROM in case that helped. I install CM 12 and life was okay. I set it to download updates (mistake) and it upgraded me from CM 12 to CM 13. Much as I like the new Marshmallow features, my S4 steadily degraded in function over time, to the point where I stopped making or receiving phone calls.
Last week half of my installed apps disappeared, and attempting to install anything through the Google Play store failed. No clue how that might happen, but I knew it was time to flash a new ROM.
That was when I discovered I could no longer boot into TWRP; it hung on the TEAMWIN logo screen. Then I started getting the Verizon screen claiming it had detected unauthorized software.
Since I could no longer operate the phone, I went ahead and put it into download mode and ran Odin3 v3.10.7 and used that to flash an OC1 ROM, the only one I had that was in .MD5 format.
Now I can’t get past a bootloop that leaves me hanging at the Verizon logo screen.
Any thoughts?
