My device variant is 920C. I was on stock rom, with Philz recovery. I flashed supersu on Odin and got a boot loop. I tried flashing dr.ketan's L7 rom via ADB sideload (since I was going to flash it anyway), and now I'm still in bootloop, and I can't even get to recovery anymore.
Symptoms: Upon pressing power button, I get "Galaxy Note 5" screen, and then it disappears with not much else. Attempting to power on into recovery (Up volume/home/power) freezes the device on "Galaxy Note 5" screen. Turning the device off is not very easy.
