With every new jailbreak release, it takes some time for developers to update their tweaks and make it compatible with the latest jailbreakable firmware. This time it is no different. Pangu released their new jailbreak tool for iOS 9.3.3 a while ago but there are still some tweaks out there in Cydia that are not compatible with iOS 9.3.3 and may create issues on your device if installed.

Installing a non-compatible jailbreak tweak may cause crashes or much worse, put your device into an endless reboot loop, forcing you to restore and start afresh. Therefore, it’s important to proceed carefully with the tweaks you’d like to install on your device.

In this tutorial, we are going to show you how to get out of a boot loop on a jailbroken iOS 9.3.3 iPhone, iPad or iPod Touch without restoring it.

How to Fix Endless Reboot Loop in iOS 9.3.3

The trick to fixing the reboot loop is to put your device into a non-jailbroken state first and then boot into ‘No Substrate Mode’. This disables all Cydia Substrate tweaks allowing you to uninstall them safely from your device and fix the boot loop issue.

Step 1: Press and hold the Lock and Home buttons together for 5 seconds or more until your device restarts and you see the Apple logo.

Step 2: After your device boots up, it is in a non-jailbroken state. Make sure that you disable the passcode along with Find My iPhone.

Step 3:  Go to the Home screen and launch the Pangu app. This time the jailbreak method is going to be different as you want to enter No Substrate Mode.

Step 4: Press the Start button and lock your device for the jailbreak process to begin.

Step 5: As soon as you see Pangu’s notification on the Lock screen, press and hold the Volume Up button until your device restarts and you see the Apple logo.

Step 6: After your device reboots, it should be in No Substrate Mode. Go to the Home screen and launch Cydia.

Step 7: Find the tweaks that are causing reboot loop and uninstall them from your device. If you get an error while unistalling a tweak, then respring your device and try again. Keep doing it until you can remove the tweak successfully.

Step 8: Once all the faulty tweaks and packages have been removed, reboot your device and re-jailbreak using the Pangu app. This time, you don’t need to hold down the volume button while jailbreaking. Simply press the start button in the app, lock your device and let Pangu carry on with the jailbreak.

By following the steps above, you can fix the boot loop issue on your device and remove the incompatible tweaks without restoring from iTunes.

It is important that you only install tweaks that are marked as compatible with iOS 9.3.3. Failing to do so will create such issues on your device.
