iPhone SE stuck on logo screen

Hi, I went to turn my iPhone on this morning, but it wouldn't get past the initial Apple logo screen. It stays stuck for a few minutes and then the screen goes black and it restarts, stuck in an endless loop. I have already tried to restart it by pressing the home and power buttons, and it goes black and restarts but still gets stuck. Pressing the power button does nothing, it won't turn off.

I have tried connecting it to power (even though I have just charged it yesterday) but there are no changes, and I also tried connecting it to my laptop, but it doesn't get detected, not even by iTunes.

What can I do? I just don't want to lose all my data.
