You seem to have flashed Black Hole, onto your receiver, judging by the boot up screen, but as you've loaded Black Hole, onto other VU+ receivers, you must know that you should get to the installation screen, as it automatically re-boots, allowing you to select your settings, set up your internet connection, your tuner, and the option to scan, for channels, or wait.
I assume that you got the message, requesting that you remove your USB stick.
Unless you have selected a channel your receiver will always stop at the start up screen, after first loading the new image.
Did you get any of the options of setting up your receiver, after flashing?
I don't understand your last post:

as soon as the update is finished and I restart, you don't tell me to go to the menu
