Preamble

Why am I doing this guide?

The main, developer's post has about 100 posts and it's really annoying to find useful information in this mess... The same questions appear all the time (I also had to ask them again). I decided to gather the important things in one place. Besides - ROM is quite unique and differs from others. If I wrote something wrong, tell me, I'll fix it. Sorry for my not perfect English.

I will look at the whole case as a simple user (who I really am! lol).

Stability

It is a subjective topic, so please take it with a pinch o salt. If I would have to rate the stability it will be 4 out of 6 (where 1 is a bricked phone and 6 is the flawless system work). System apps (like Documents or Themes) rarely can crash, but the system reboot fixes it. Generally every day usage is completely fine and you'll never get a random reboot on the go. What users have been reporting are problems with crashing default music player (confirmed by me). I personally noticed, that while using ProPlayer (IMO one of the best music players) songs rarely are randomly muted or skipped. Another thing reported is a signal losing (I haven't experienced it). GPS for me is going like crazy.

Storage mysteries

I don't know, if it's a bug or a feature, but there have been done serious changes to storages' permissions. It's probably an effect of allowing convertion of external SD Card, to internal memory. But let us start from the begginig...

When you'll first boot to the system, you will be asked, if you want to keep your SD Card memory as mass storage device or if you want to format it as internal memory.

1. If you won't format

Apps will be only able to use the internal memory. They will have no permissions to change anything or write to SD Card. It means, that you won't be able to download files to it or even manage it with file manager (even if it will have root permissions!).

You will be able to access internal and external memories from TWRP.

2. If you will format

You won't have access to old internal memory from system (practically it will disapeare), but instead you will gain full access to your SD Card.

Internal and external memories will be still available through TWRP.

Remember to make a backup to your PC, before formatting ;P

TWRP

You will have to flash TWRP 3.0.0 to get full access to SD Card after formatting.

Super SU

If for some reasons you don't want to use build-in root (for example I really don't like this hash sign on the statusbar), here's what you do:

1. Turn OFF build-in root in Developer Settings (if you don't, you'll get bootloop)

2. Flash Super SU through TWRP with the flashable ZIP from the Official thread (don't use Super SU App for this!) http://xdaforums.com/showthread.php?t=1538053

3. When you boot to system, Super SU with root will be ready.

4. Reboot again to fix the Super SU app (it can crash)

XPosed

XPosed works with official version for SDK 23 arm.
