iPhone Resetting Jailbroken iPhone 5C

[richtercamden]

I think I'm screwed. I jailbroke my iPhone 5C late 2015, and it had worked fine until recently. I'm not sure what went wrong. As I said above though, I'm pretty sure I'm done for, and I'm worried. My Phone was restarting randomly, so I decided to restore a backup from iTunes. This went successfully up to the point of actual restoration. In the middle of being reset, my phone restarted and cancelled it. So, I tried to "Erase all content and settings" from the phone itself. Now, it just goes a little on the erase, then crashes, restarts, and tries again. I can't restart it, I can't turn it off. Any help? I'm freaking out here.

Try putting it into DFU mode.

Instructions here:

Alternately you can download RecBoot and use that to enter recovery mode: http://veryrite.com/2011/03/05/download-recboot-2-2-exit-enter-iphone-recovery-mode/

Then open iTunes and click hold down OPTION, and click RESTORE, not update...manually select the latest firmware... You can get it manually from here:

"Erase all content and settings" on a jailbroken device will always put it in a boot loop, never do this again. The only thing you can do now is restore to the latest signed iOS version signed by Apple which is iOS 9.3.1 which has no jailbreak. I hope your original intention was to remove the jailbreak completely as that is what you have essentially done. Put the iPhone in DFU mode and restore, that is your only option now.

Thank you all so much. I knew that boot loops happened with quite a few things in jailbreaks, but I didn't know that was one of them. I will keep this in mind. Another question though, it seems to be working fine as a new phone, but it still abruptly restarts with no explanation, whether it's hardware or software. Any ideas? Thanks again.

My iPhone sometimes reboots overnight while charging for no apparent reason. This has been an ongoing bug in iOS 9. I am on iOS 9.0.2 myself and this happens a few times a week. I have learned to just live with it for now.

I had that issue on 9.0.2, i updated to 9.2 before I took my phone for the camera recall. The problem is no longer there, so either 9.2 fixed it, or the camera repair fixed it.
