New hub v3 owner. When adding hub to app, it gets stuck on update page

Solid blue?

Blue (solid)

What it means: Attempting connection to the SmartThings cloud/servers

What to do: A solid blue light is expected during the normal setup process and when downloading firmware updates (in some cases). However, if the light remains solid blue for longer than 5 minutes, this indicates the Hub is unable to establish a connection with our servers. This problem can occur when outbound traffic from a local network is being blocked. Double-check your network settings and make sure the following ports are open during initial setup: 11111, 443, and 39500

I had to reset my hub and now going through adding it to the app and it’s stuck on updates at 0% with the light still flashing green and red. Got this hub in May so no longer can return and get another one. Anyone have any luck getting it to work.

I’m new to home automation too. My smart hub V3 registration would complete up to 64%, then show a message “couldn’t register” tried all the suggested solutions multiple times, with the same result. I was just about to give in when I realised one thing I hadn’t done. I deleted the pre-installed app from my phone and re- installed it. Tried registration again instant success. May have been a coincidence, but worth a try.

So I was having the problem where I couldn’t setup the hub in wireless mode. Not even 1% when doing the update.

What I’ve done and hope this helps other users with the same problem:

  • Do the normal process when adding the Hub v3 in wireless mode

  • When you reach the point where you need to update plug the ethernet cable.
    The app will keep failing the update but the progress keeps increasing. So just keep hitting the “Retry” button until you reach 100%. If you get stuck on 99% just kill the app and open it again.

  • Eventually the led will turn green if not unplug the hub and plug it again.

  • After you get the green led on you can remove the ethernet cable, unplug the hub and plug it again.

This at least worked for me. Junkie process as hell but so far so good


Alright, i got his thing connected twice but had the same issue numerous times, 1 st time i let it update and install overnight. Was working when i woke up the next morni g so might be a time thing. The other time, the bar was stuck on 68% (downloading). I unplugged the ethernet cable, then plugged it back in and the screen changed to installing. During the installing process it go stuck on 99%. I disconnected the ethernet and plugged it back , then disconnected the power and plugged it back. The light went from yellow, to flashing blue, to solid blue, then green. After a few seconds once the light turnes green, it finished updating.

Mind you the whole process still took me 20 minutes once i started unplugging stuff.
