Quest 3 blocked in reboot loop

As of today, my Quest 3 (received like 9 month ago) is stuck in a reboot loop. I got the spinning blue logo, and image forms (from front cameras) then black screen and spinning blue logo again. And, of course, with the boot sound looping also.
I tried "factory reset" didn't change anything.

With different levels of battery, same result.

What should I do?
