My son's AppleWatch 4 won't boot after attempting pairing

[Giuanniello]

Read about this issue while looking for a solution, Apple Watch Series 4, paired with his iPhone 8+ and working, when he upgraded to an iPhone 11 and tried to use the watch no pairing nor possible to update, we are trying with my up to date iPhone 13, with his 11 and with the old 8 it was paired with but while with my phone it says there is an update but no way to go through it with the other two phones pairing fails over and over, been trying to reset the watch by pressing the crown and the button till reboot and now I am watching the apple logo and that's it.

Anybody found a solution for this?

Grazie

edit, after severa attempts at pairing now I can only get the apple logo even after rebooting, it is in a loop

I had a problem like that when the watch was trying to check for an update, close all the open apps on your iPhone and try pairing it again, that worked for me.

Issue being the watch keeps rebooting, no way how I reset, pushing the crown or crown and button nothing changes, it keeps showing the apple logo then reboot again and again and again, seems bricked with no apparent cause

If I had a four, I’d give it a boot.
