I upgraded to MM back the beginning of the month, tripped my Knox bit (I had rooted via PingPong root on Lollipop), but I was eager to go to MM and try Xposed so I could improve the horrible battery life.
I had the system working fine, rooted using CFAR, and no problems. Randomly, about a week ago, it just "lost" root. I wasn't sure why, and CFAR from Odin wouldn't bring it back. I did a flash with SuperSU in TRWP yesterday and it worked, and I did a NANDroid backup, saved it to my computer, and installed Xposed... On a stock ROM.
And my phone has been a continuously rebooting brick ever since, no matter what I do.
So, I've tried everything I can think of. Because my data was completely backed up, I did a complete wipe, and nothing. I tried flashing the Xposed-uninstaller.zip and that supposedly worked, but the phone reboots about 53 seconds after it starts up, continuously, no matter what.
I've tried the default MM firmware, tried letting it go through it's paces on its own (but it just reboots every 53-57 seconds), and also tried with a fresh clean default MM ROM, which does dump TRWP, then restart into the default bootloader, have it dump the cache and do a complete re-wipe, and nothing. Still restarts.
With the stock MM firmware load, the first boot it always stops at 32%, reboots, and when it comes back up it sometimes makes it through "optimizing xx of 30 applications" but always reboots and comes back to it over and over, ad infinitum. Sometimes it makes it to 30, usually it doesn't, but it always fails, reboots, and comes back to the same menu on a stock ROM.
ADP and MTP in TRWP work fine, and all my data is backed up. So, I'm willing to do anything to the device; nothing left on it to care about (I already tried NAND erase in Odin and format partitions in TRWP). It still continuously reboots at around 53 seconds.
I've also tried custom ROMs loaded up from TRWP (Renegade 1.1 and TeamSPR V3). They apparently load - everything looks/works great from inside TRWP - then invariably they reboot at about the 53 second mark. Can't even get Renegade past the boot screen.
Nothing was done hardware-wise to break it; the Knox bit flipped three weeks ago, and the SuperSU upgrade had been working fine. The action that killed it was attempting to install the Xposed framework on a default ROM that only had SuperSU installed. But I've since installed a default ROM and ran the Xposed uninstall to no avail. The uninstall Zip in TRWP gave all the right responses that it worked, but it still rebooted 53 seconds after restart. Continuously.
I don't even know how to go back to Lollipop because attempts to load G920PVPU1AOCF in Odin gives me an immediate failure of "SW REV. CHECK FAIL. DEVICE: 3, BINARY: 1," so downgrading appears to be out of the question.
Someone has to have seen something like this before or there's something I'm missing. About the only thing I can think of is to try a custom ROM install and force the Xposed framework again without even letting it boot up (because it won't anyway) from a TRWP install. I'm going to attempt that while hopefully someone else comes up with ideas for me...
