I have the 1 year receipt, so I know that's not the problem. But one night my phone rebooted and it went back to the stock iOS, and I had the reboot fix installed (from reddit: https://www.reddit.com/r/jailbreak/comments/4wk3qq/release_ios_9_reboot_fix/). I tried to re JB but it didn't work, and I also tried to turn off the passcode, turn on airplane mode, and turn off the notifications, and none of these worked, though the bytafont font is still in use on my phone. When I tried re JB with the passcode off and holding the volume button down, it went back to stock, but had the icon masks and bytafont working. Usually when i try to re JB it is on my custom bootlogo for a couple minutes, and flashes once, and then goes back to the stock boot logo. Big thanks to anyone that could help me!
