LeapFrog Epic

The LeapFrog Epic (styled as LeapFrog epic) is an Android-based mini-tablet computer produced by LeapFrog Enterprises. Released in 2015, the Epic is LeapFrog's first device to run on Android; most of LeapFrog's mobile computing devices for children run on a customized Ångström Linux distribution.

Sideloading APKs

A guide for enabling Unknown Sources can be found here. Note that you need to update your Epic to a later build to be able to access the App Center settings directly from the Parents menu.

There are two ways to install APKs, one through downloading stuff off the Browser, and the more advanced method being ADB.

For the latter, you'll need to download the latest ADB and Fastboot binaries, install the necessary drivers, and enable USB debugging. You can access developer options using this guide I wrote, but instead of tapping on Unlock selection, look for the Developer options menu item and tap it, then tick USB debugging to enable ADB mode.

Now plug your Epic to a computer, then using a command prompt, run the following command:

adb devices

You should get an authorisation screen, and make sure to tick the checkbox so it would be authorised the next time you plug your device in. The command prompt should also display something along the lines of this:

1111111111111111 device

Once that's done, you may now install APKs using this method. To do so, key in the following:

adb install foobar.apk

where foobar.apk could be any APK file you have lying around. If done correctly, it should show up on the application menu.

ROM backup

Work-in-progress; to be updated especially once the bootloader is unlocked
