what type of apps are onboard that Firestick?
You need something similar to an AppInstaller or FileBrowser or FileManager or TotalCommander or something that will install the Kokaleka app.
The Kokaleka app can be found in an .apk file, which is posted in the thread shown below.
Inside the .apk is the app and the app is what is installed on your system.
The .apk is basically a carrier of an app.
So grab that .apk and load onto storage device and use a File Manager to load that app from the .apk file.
Once you open one of them Managers, they basically take you thru the steps needed, there is only 1 or 2 steps.
You also will need to 'Allow from Unknown Sources' before doing anything.
You have to set that in one of your menus. Probably in a Security and Restriction type menu.
Or just go ahead without setting that and upon trying to install the apk, the Firestick may tell you that you need to set that restriction and will ask if you want to now and will take you to that menu option. So you can access it like that too.
