Need help with old AI co troller updating forware is stuck

[Mooser16]

So I have original ai hydras gen 1 and the controller I bought when I set up my 90 gallon tank 6years ago I had to take it down when I moved 3 years ago and now I am starting my tank over again the problem is these lights don’t connect to the new ai app so only can use the old controller to use the lights ....so I went to update the firmware On The lights and I did it over wifi because I do. Or have a desktop with Ethernet port and now it is stuck on one screen and doesn’t go anywhere ....it’s been over a week
