    What are the key causes of the iPhone boot loop?

    Broken iOS update

    The process of iOS upgrade in iPhone is simple. Go to Settings > General > Software Update.

    However, at some point, if the update process is interrupted due to unstable internet connectivity or power issues, it may result in possible anomalies like an iPhone reboot loop. If it happened because of the latest iOS upgrade, then downgrading to the previous version can resolve it.

    Jailbreaking

    Jailbreaking is a safety loophole used to terminate software restrictions and security limitations to get unrestricted access to iPhone apps and files. As a result, your iOS device becomes vulnerable to virus infection or malware attack, causing errors like the iPhone being stuck in a boot loop.

    Unstable cable connection

    While updating or backing your iPhone data on iTunes or iCloud, an unstable or bad cable connection to transfer files between two devices (iPhone and your computer or Apple server), can also fuel the iPhone reboot loop.

    Faulty hardware

    In addition to the software glitches, hardware issues like malfunctioning battery connectors in an old iOS device or a broken component in it can cause the iPhone to keep restarting error. If you accidentally drop your iPhone on the floor or in water, it will damage the hardware causing a reboot loop.
