What is the problem?
Can't install Octo4a on LG Vu3 running Android 4.4.2
What did you already try to solve it?
I have set the LG Vu3 to install apps from unknown sources and turned off verify apps
Tried Octo4a versions 1.0.0 through to 1.1.2, the installer would run "installing bootstrap (ARM)" and then crash, saying "Unfortunately OctoPrint For Android has stopped."
Then I tried the latest version 1.2.5, which throws a "Fatal Error" and the following log:
No bootstrap detected, proceeding with installation
Arch: arm
Downloading bootstrap 0.3.0 from https://github.com/feelfreelinux/android-linux-bootstrap/releases/download/0.3.0/bootstrap-armv7a.zip
