Why won't my phone come out a boot loop?

[iMore Question]

First off I have an iPhone 5s with iOS 9.0.2 jailbroken. I was updating a source update when after the resorting it went into boot loop and then I was able to get it out of the boot loop by the sleep button and volume up button. But... None of my jailbreak sources were there and cydia keeps crashing so I tried to reset it mobilely because I was at a football game when it happened. And in the middle of the reset the little bar at the bottom disappeared and went to the apple logo screen then it dimmed and then the white background turned yellowish like on the f.lux tweak.mand now I can't do anything with it but charge it.

Hopefully someone will have some advice for you soon, but this is why I don't mess with jailbreaking my devices.
