What you will need is a few things. I was lucky in that a family member gave me their frontier info so I could use their login for live tv but you can also do this without that.
So the first step is installing Google play services on your firestick which there are numerous posts on how to do that here so I won't go into detail on that one.
Download on your phone apps2fire original on your phone. This can be found in the app store. From there you can install any app through this app. I installed the frontier app. I have also installed showbox app in which both were tested and working.
My final step was the one thing I researched on. Because they are both touch screen and I wanted to use strictly my remote I began hunting. So in order to accomplish this I installed Mouse Toggle.
The last thing I am researching is to spoof my family members home wifi to make the frontier app think it's on their network to unlock all the channels so any help on that would be appreciated.
After these easy steps I have live streaming cable as well as movies galore. I can post links to the numerous sites I found everything on if it is allowed. If you have any questions feel free to respond and credits to anyone that posted this info before.
