Static ARM adb and fastboot binaries for Android built with the NDK.
Marshmallow removed adb from the /system/bin directory. For those wanting this functionality back, here’s a simple installer to push static compiles of adb and fastboot to /system/xbin and uses a command wrapper to point adb to the correct HOME directory and set TMPDIR for compatibility. Detects and supports “systemless” install via SuperSU/Magisk as well. It can then be used from Terminal while booted from that point on.
