How do I exit safe mode on my jailbroken iPhone?
Noticed your iPhone status bar says "it Safe Mode" instead of the time? This means that SpringBoard crashed and extensions have been disabled. Touching the words Safe Mode in the status bar brings up the following dialog box, giving you three options on how to proceed.
Here are the recommended steps to exit iPhone safe mode and return to normal operation:
1. Select Restart from the Safe Mode notification dialog. SpringBoard will restart and if the conditions that caused the crash have been resolved you are now in normal mode. Should this fail, try rebooting the iPhone by holding the sleep button and sliding to power off.
2. If step one still leads to Safe Mode, it's possible that a recently installed Cydia package such as an extension or tweak is causing the problem. While in Safe Mode, use Cydia to uninstall the suspected extensions or tweaks. Restart SpringBoard.
3. Still in Safe Mode? Search for and install the app Crash Reporter from Cydia. Open the Crash Reporter app and select SpringBoard. If crashes are found, the first one could be the problem. Follow step two to remove the offending package using Cydia. If restarting SpringBoard or rebooting the iPhone continues to result in Safe Mode, move to step four.
4. Restore your iPhone. Make sure not to upgrade your firmware to a version that can't be jailbroken. iTunes will want to update your iPhone operating system to the latest version by default. Follow these instructions to use redsn0w to jailbreak a specific firmware version. If your SHSH hashes are saved, you can downgrade or install a specific version of firmware then jailbreak.
