[Nexus 6 Themes and Apps] mattbta:
BusyBox v1.24-1.Stericson -- I played with all the different install paths trying to see if I could get rid of the tweak errors, but no dice. Strangely though, I was able to get it to start processing in Viper. Not sure how though.

Should there be edits to build.prop via flashing 7.2 Redux? I don't see any. I also see an error when twrp tries to execute the tweak update zip. Here's the logs from latest flash:
