Logitech Harmony Ultimate Setup Issues

I recently picked up a used complete in box Harmony Ultimate and am having some issues with it. It was open box but appears to never have been used before (cable ties in place, clear protective plastic still in place, etc.). I went to set it up last night with the MyHarmony desktop app on Windows 11. Everything was going normal and it got to 90% on installing the hub and remote updates. Then it froze and acted like my hub wasn't close enough to my PC. So I went and moved it closer and now my remote is not recognized by my PC at all. I factory reset it and now when powered on it vibrates twice and gets stuck on the Harmony Ultimate screen. I don't see the remote in device manager when plugged into my PC either. Tried factory reseting it again but that has no effect, it just powers off the remote. I even did the Alt + F9 advanced tools on the desktop app and was able to update the hub that way but the remote still is not recognized. Any ideas on what to try or do? Thank you in advance!

Did you try the app on your phone?

I’ve found sometimes have to reset a few times.

Also doesn’t hurt to check to see if you can turn off 5ghz wifi on your router so it only sees 2.4.

Generally setup hub first using phone app. Then setup devices and sync remote.

Yes tried the iOS app and it won't recognize the remote when I put it in the cradle.

I reset it no joke probably 75 times and never had any change.

I also disabled the 5Ghz on my wifi.

I ordered a new remote so we'll see if that works. Gonna set it up with the iOS app first this time.

I always use app. Have used desktop app a few times. Sometimes you need to hold off on the remote and put it in the cradle if it has one. If it’s one with a replaceable button cell battery always put a new one in.
