Why is my 6 month old lumia 635 restarting and won't stop restarting?

[Windows Central Question]

So, as mentioned above, my lumia keeps on restarting and restarting over and over again. Actually this problem started out like this- I would unlock the phone and without me pressing down on the power key, it would want to restart itself, as you probably know the screen that is "slide down to power off". So then, after some time, my lumia would just restart by itself and eventually got to the point where it was essentially stuck in restarting. The phone vibrates when it is turned on, and every couple of seconds it would vibrate and, even though the previous restart it didnt get to the main screen, would restart again. Basically, it was stuck in the initial first screen, the "nokia" that pops up when you first restart the phone and it would do this in loops. I've taken the battery out, let the phone cool, put it to charge......same problem persists. I've also done a factory reset on my phone about 2 months ago when I had a problem with tmobiles network.

If a fresh Hard reset doesn't help, send to Nokia Care for repair.

Might be worth taking out an SD card first though if you are using one and seeing if that has somehow gone bad and is causing issues.

Re-seat SIMs too (with power off)

If a hard reset doesnt work....then you need to do a fresh os install,with Nokia recovery tool/lumia reset tool....make sure you use the correct os...go to xda forum for instructions

All right man. My 635 did it to me the same thing twice. I took the battery out for a while, put battery in, turned on. Also I tried to take battery out, put on the charger then t battery in. It eventually worked.
