2018-03-21 00:28:45: Your device does <b>not</b> support direct flashing!

Flashing functionality <b>disabled</b>!

Activate flashing functionality by flashing a SALT compatible LAF partition.

Download it right here for <b>any</b> G4 model (requires unlocked device + TWRP):

<a href='https://www.androidfilehost.com/?fid=818070582850495147'>SALT-compatible-LAF_flash-in-twrp.zip</a>

You can still use many of the features SALT offering - just not the flashing part.
