[Nexus 6 Themes and Apps] mattbta:
7.2 works on Rhapsody, Google Play and Amazon, but not Deezer, which uses FLAC. It is strange though, I was able to get Dolby working, but no Viper processing for Deezer. I use Deezer almost exclusively since my family uses the others during the day.

TWRP output:

I:operation_start: 'Flashing'

I:Zip does not contain SELinux file_contexts file in its root.
