AllianceRom has a little script thing to reboot to recovery and I was in there anyway so I just rebooted from there. I'm now stuck at the initial teamwin screen. I can't boot normally, I just keep running into the teamwin screen, and it won't progress to the point that I can actually do anything in twrp.
I can get into download mode so I thought to try odin-ing the latest version of twrp, but I still run into the teamwin screen and full-stop.
It's un-bootable, either into the normal phone or recovery, and I have no idea how to proceed from here. Phone's been fine prior to this - I've been on mj9 and build 24 was running great, so there aren't any major problems I can point to that may have caused this. I'm starting to freak out. Any suggestions would be really, really appreciated.
