Bricked RB450

Hello to all and happy new year.

After trying to downgrade from a beta version I bricked my RB450 and I cant bring it back to life. I cant see it with winbox, netinstall or serial I am not sure if I am doing it right thought. I made a video so you can see my problem. Any help is appreciated.

Thanks.

What shows up on the console with the serial cable plugged in? Also, for netinstall make sure you use ether1.

I use putty and I see nothing. It doesn’t do anything. However I finally got netinstall to work. I installed 5.22 and 4.17 and when I press reboot it wont boot and does the same thing as in the video the fourth and fifth lights comes barely on..

Deleted because not related.

you are right about that but the problem appeared before I moved it out of the case and still goes on nothing changed. I don’t think I damaged it because of me handling it like that…
