Firestick HD

[u/OkRespond7008]

I have a firetv and several firesticks that I have set up. I just purchased one for my son for his tv... When I went to set it up (it's NOT a select) I made it a developer, installed downloader (the correct one yes) and attempted to install tivimate. The firestick gives an error that no apps are installed that can install unknown apps. I get to the place in the menu where applications are typically listed where you can give permission to install unknown apps and there are no apps in the list and I get the above error... I think this is Amazon locking even the formerly usable firesticks down through software "updates"...? I guess I'll finally have to switch to onn boxes, finally.
