One of the most dreaded issues that you can encounter when working with your iPhone, iPad and iPod touch is the infinite or endless reboot loop. It is the state where your iDevice is stuck at Apple logo, never proceeding and instead restarts. There are way too many variables that can lead to an iPhone boot loop such as installing jailbreak tweaks, custom firmware or changing themes. When faced with endless reboot cycles, there are several iPhone boot loop fixes that you can try.
How to Fix iPhone Boot Loop Issue
Hard Reset / Reboot
When it comes to iPhone troubleshooting 101, you should know that a hard reset can solve most problems on both jailbroken and non-jailbroken devices. So before you do anything else, it's a good idea to do a hard reboot first to if it solves the boot loop issue at hand. To perform this boot loop fix, simply press and hold the Home button together with the Sleep/Wake (or Power) button for several seconds until you see the Apple logo again. This comes in handy if one of your apps becomes stuck or unresponsive.
Fix Endless Reboot Loop By Disabling Mobile Substrate at Boot
Sometimes I have installed tweaks or apps that turned out be incompatible, broken or glitchy. This almost always leads to an infinite boot loop and may lead to a device restore, which we all know is something we don't want to do. So you can bypass the endless reboot cycles, you can try disabling Mobile Substrate, the very framework that supports 3rd-party apps, tweaks and patches. Note that this feature called Mobile Safe Mode is only available in version 0.9.3997.
To disable Mobile Substrate and bypass iPhone boot loop, simply press and hold the Volume Up while your device is booting up. If you have a faulty volume button, you may also use the Clicker (not Volume up) button on your Apple headset. This puts your device into Mobile Safe Mode and giving you full access again. Now that you have passed the annoying reboot cycles, you can now uninstall the broken tweaks or extensions from Cydia.
Boot Loop Fix Using Redsn0w
Just in case the above solutions don't work in fixing your iPhone boot loop issue, you can try using Redsn0w. If you are caught in the an endless boot cycle while in iOS 6.x.x, you can use the latest version of Redsn0w (download here) to boot your iPhone manually. Just follow these steps:
- On Redsn0w's main page, click Extras.
- Click Select IPSW.
- Point the file browser to iOS 6.0 (NOT 6.1, 6.1.1, 6.1.2 etc.). Click Open.
- While still on the Extras menu, click the Just Boot button.
- From here you'll see the DFU mode instructions. Click Next to proceed and follow the onscreen instructions to go into DFU mode.
- Now, you just have to wait until Redsn0w is done with the booting process and see your device booting past the Apple logo.
NOTE: if you can't click Next, perform a hard reset by pressing and holding the Home + Power button and you should see the Next button enabled. Alternatively, you can perform the DFU mode now and Redsn0w should recognize the device.
How to Prevent iPhone Boot Loop Issue?
The main reason why folks get into this annoying problem is due to broken tweaks and extensions. So before you install anything from Cydia, make sure that you verify that the firmware version you have is supported. Take the time to browse the info page of the jailbreak tweak or app so you don't end up with a glitchy installation.
