Right now I have TWRP 18.104.22.168 on it. I've apparently broken the /data, /cache, and internal storage, they're all unable to mount now. I cannot user the PWR and VOL DOWN buttons to get to fastboot anymore, it just ignores the fact that i'm holding those buttons down and only boots into TWRP. I can't choose the ADB Sideload option in TWP, it fails because of the broken partitions. I am able to connect to it in adb from my desktop, and I can push files to it, but I haven't been able to find anything that lets me fix the partitions or fastboot.
I can provide any other info necessary, but I have no idea what further to do with it.
