The reason we purchase Nexus devices is the ease at which we can root and mod them. If you have been flashing roms on your Nexus 6 you may have noticed one little thing in your favorite rom that may or may not be driving you bonkers. Kit Kat sounds on a Lollipop rom. If this has happened to you there is now a flashable zip that will give you back your Lollipop sounds! Simply download the file from the link below and flash in recovery. The file even includes the stock Nexus 6 boot animation. You can actually unzip the file and insert whichever boot animation you like. Head to the link below for the files and full guide.
