DivestOS/Scripts/LAOS-14.1_Deblob.sh

#!/bin/bash

#Goal: Remove as many proprietary blobs without breaking core functionality
#Outcome: Increased battery/performance/privacy/security, Decreased ROM size
#This script and subsequent builds have been tested

#
#Device Status
#
#Fully Functional: bacon, clark
#LTE Broken (Potentially Unrelated): mako
