HOW TO RESOLVE BOOTLOOP ON UMI SUPER?

Matte23

Hi guys, I have had a problem last night updating my Umi Super via Official Rom (which is in the link in the post concerning the android 7.0 update for Umi Super). When I turn on my phone, it stops on the umi screen and it can't go on to the classic launcher. What can I do? I'm really worried.
Thanks for your kind replies
