Miscellaneous :

How to compile TWRP :

croot; export ALLOW_MISSING_DEPENDENCIES=true; export PATH=$PWD/bin:$PATH; source build/envsetup.sh; lunch omni_ac50hello-userdebug; mka clean; mka recoveryimage

If you get a SyntaxError from Python this may mean that your /bin/python is Python3 but Android 8.1 needs Python2, so do this then rebuild
