Help/Support iPhone doesn't boot past the Apple logo, then turns off

DoppleGangeriosGods · September 18, 2017

While texting in messenger and imessenger my device would get a kbd crash (keyboard crash?). I tried to find the culprit, so I began by turning off everything listed as BytaFont3 in the Cydia Substrate using iCleaner Pro. The phone immediately rebooted then went into Safe Mode.

Mistakes were made: I got distracted and instead of removing all tweaks that might be causing the Safe Mode, I instead tried to jailbreak my device. Yalu wouldn't open, so I uninstalled it and attempted to side-load it using Cydia Impactor. For some reason when I tried to install Yalu, Cydia Impactor gave a Locked_Error. I then decided to [edit] force restart and the device did not boot back into Safe Mode.

The problem: Now when I power up the device, it reaches the Apple logo for about 60 seconds then turns itself off.

Details about device: iPhone 6s+, Yalu iOS 10.1.1

Questions:

1) Without the Yalu app installed, is it still possible to get into Safe Mode?
2) Is there a way to save my Jailbreak?
3) If I can't save my jailbreak, is there a way to save my data?

Have you tried going into Safe Mode but holding the buttons that work with your device?

And does iFunBox recognize your phone when you're in the Apple logo?

I found instructions to manually boot into Safe Mode for the iPhone 6 which I assume would work the same way for the iPhone 6s+. I powered up the device and then held down the Vol + button, but the device turns off while it's still on the Apple logo.

During the 60 seconds the device is on the Apple logo, iFunBox doesn't recognize it.

I went into DFU mode, and iTunes recognizes my device, but iFunBox still doesn't.
