To install, download full zip.
If you are using TWRP recovery, you must flash the FULL zip and ensure that it is version 184.108.40.206
Factory reset is highly recommended as all reported issues have been from dirty flashers :-)
So, in TWRP, wipe, then swipe to factory reset, the option says it doesn't touch internal USB storage.
Go to install, select your download folder, tap on the zip and swipe to install.
During setup, skip Cyanogen login and don't use trucaller and turn on all location services, even when Cyanogen purposefully lies to you and says that you had turned off that option in a previous version. Yes, they lie to you.
Now allow all your apps to install.
Gallery (if you want)
Go into settings, accounts, Google and turn on googly contact sync (Cyanogen really don't want you to use it) and calendar and all the ones that are turned off.
Go into Settings, Security, Device Administration and disable Cyanogen remote wipe.
After all your apps are installed, go and install the Google now launcher and Google Camera manually. Cyanogen don't like you installing them automatically (I had them on previous installation but for some mysterious reason they didn't come back automatically).
Now you will notice that the cyanogen dialer is rubbish, the starred contacts are tiny and it doesn't use the Google Caller ID. To fix that you can install the Google phone app.
Need to do that in TWRP, and add root before you reboot.
Now use ES File Explorer and go to system/priv-app and delete the Cyanogen contact and dialer app so you don't have duplicates.
Done. This took me about ½ hour, all told.
