Sideloading Apps on Supernote A6X2

Hi all,

To begin with-- Standard Disclaimer: I take zero responsibility for anything that follows. That said, in my assessment, the procedure is as risk-free and straight-forward as it gets when it comes to side loading apps on any Android device (eink or otherwise). I just created this account today to post this, and (most likely) will not log in after; I'm internet shy. Also, please do not ask/request the Supernote team for support, since this goes beyond the prescribed operational range of this device, although I hope you will help each other.

Step One: Bring up the Android settings menu.

This was discovered by /u/Organic_Software8272 here.
Can be reliably accomplished by: turn off Wifi > Kindle app > More > Settings > Manage Additional Fonts > Try downloading anything > Message pops up leading you to Android settings (this is just one path).

Step Two: Enable USB debugging

Steps: Go to "Android Settings" > About > Click on Build Number 7 times to enable developer options > Enable USB debugging from System Settings -- Developer Options.

This -- USB Debugging -- is a toggle switch.

Step Three: Sideload App

Post enabling USB debugging--
1. Connect device via USB to your Mac/PC/device.
2. Install Android platform tools (e.g., on Mac with Homebrew, https://formulae.brew.sh/cask/android-platform-tools).
3. In a terminal/shell, "adb devices" should list the Supernote.
4. Download any APK (e.g., https://f-droid.org/en/).
5. Open the same folder in a terminal/shell, and type "adb install filename.apk".
6. To open installed app, "Supernote settings" > Apps > Supernote App Store > App Name > Open. Will be automatically listed in the sidebar after.

Additional Notes

If you install F-Droid, or Aurora -- these are (independent) app stores -- subsequent installs can take place on device. In a sense, it might be easier to side-load apps on nomad than what I have seen for A#X; these are just usual steps on any (non-Play-store-enabled) Android device.
