2) Backup -> swipe to backup

3) Wipe -> Factory reset
When updating existing superluminal CM11 ROM:
4) install (select from storage or via adb sideload)
5) install gapps (if you need/like)
5.1) Gapps can be downloaded from various sources. For example from here

Performance profiles explained

  • Power save: Max CPU 1.2Ghz, slower CPU governor. If battery level <15% keylights are turned off and screen maximum brightness is limited. This is normally good enough for normal use.
  • Balanced: Max CPU 1.9Ghz, balanced CPU & GPU governors. If more performance needed, use this mode (e.g. heavy web sites).
  • Performance: Max CPU 2.1GHz, balanced CPU governor, performance GPU governor. This is good mode for heavy gaming.


Battery saving tips

1) Use ‘Power save’ profile, when ever possible.

2) Set screen brightness as low as suitable for you.

3) Set screen off max CPU in ‘ROM Extra Settings’ to as low as suitable for you. e.g. I have set this to 883Mhz

4) When not in use (e.g. nights), turn off data (mobile, wifi) and battery consuption will be VERY low.

5) Use Privacy Guard to disable wakeup, keep awake and location permission from apps/services you don’t need. This is really good battery saver! BUT if you disable from certain services that OS needs, some apps may malfuntion and consume even more battery.
