Apple iPads are generally reliable computing devices, but like all computers they misbehave at times and need to have the operating system reinstalled. If you have an iPad that has been randomly restarting, suffers frequent app crashes or generally behaves erratically, you may need to go beyond simply restoring the device and reinstalling the firmware entirely. Recovery mode allows you reset the iPad to factory settings and reload iOS while bypassing the device boot process, leaving you with a fresh install. Note that restoring iOS on the iPad will completely erase all content stored on the device, so make sure you have a recent backup to restore from once the OS is reinstalled, if possible.
