Phone restarts itself whilst it's restarting itself (Alcatel A3 XL)

[Android Central Question]

I was just watching Youtube on my phone but it abruptly powered down. It started to boot back up again but strangely it shutdown again without any input during the boot up screen. And now it's stuck in this infinite loop of crashing while trying to restart... My phone is an Alcatel A3 XL if anyone knows how to fix this.

Welcome to Android Central! That's called a bootloop, and can be due to various problems -- corrupt firmware, defective hardware, or a failing battery. Try forcing a shutdown by pressing and holding Power for about 20 seconds, then see if you can boot into Recovery Mode and wipe the cache partition: https://www.hardreset.info/devices/alcatel/alcatel-a3-xl/recovery-mode/
