I'm having same issue, how do you install new frame ware to tv . I've done all the other steps.
The supported app must be installed on your mobile device and your Roku streaming device to use casting. You must also connect your phone or tablet to the same wireless network as your Roku device.
How to cast from a supported channel
To begin casting, you must install the channel and matching mobile app and start playback. Refer to the instructions below for help.
During playback, you can use your mobile device to find and begin casting another program, do something entirely different, or turn it off completely—all without affecting playback on your Roku device.

Hi @Angelw06,
Thanks for posting here in the Roku Community!
We understand you have a query on how to update the new firmware. You can do a manual update by pressing the Home button on your remote. Then go to Settings > System > System Update > Check now. Then, if an update is available, select Update Now and wait for your Roku device to restart.
For further reference, you can visit our support page: How to update the software on your Roku TV or Roku streaming player.
Please let us know if there's anything else we can help you with.
All the best,
Chel

Roku cast can not be installed, I only have a 15g hot spot on my cell phone. So I screen share almost everything I watch on to my TV.

What supported app? I have had this tv for 8 years and have smart view already installed on my phone. I have been screen sharing to this TV for 8 years and have never had to have a app on phone nor TV while having to use wifi. The smart view still works on my other TV I have.
