#Goal: Remove as many proprietary blobs without breaking core functionality
#Outcome: Increased battery/performance/privacy/security, Decreased ROM size
#TODO: Automate TimeKeep replacing, Clean init*.rc files, Create TWRP version, Remove more variants

#
#Device Status (Tested under LineageOS 14.1)
#
#Fully Functional: bacon, clark
#LTE Broken (Potentially Unrelated): mako
