Issue with my mixer x1850

Hey guys, I tried to upload to 1.7 from 1.3, I started doing it step by step, when I download the firmware and it was suppose to be ready, the mixer didn't restart and I had to turn off and on again and now its bugged, the lights are turning on like when it's loading before it start working but it just stays like that(see the picture attached), I already tried multiple times to install it in instals mode form the mixer but no luck yet, I can't even use it with the 1.3 firmware because it is bugged. Any recommendations? I already tried contact denon but no luck yet. Hopefully I can get some help. Thank you
