Rom CM12.1 b4 (Lollipop 5.1.1)


This rom works on the following devices:

  • Allview P7 Xtreme
  • Gionee Elife E7 Mini
  • Himax Pure 3
  • Symphony Z III



  1. Download Rom
  2. Go to Custom Recovery
  3. Do a backup of your present rom
  4. Wipe Cache/Data/System
  5. Install ROM CM12.1b4
  6. Don't Wipe Dalvik Cache!
  7. Reboot (It may take a while longer than usual. Up to 5 minutes on first boot). Please  be patient.
  8.  In the end you will have a fully working Android 5.1.1 Lollipop ROM!


What's fixed:

  • Improved UI
  • GPS works great now
  • Battery time improved by 10%
  • Camera works fine now
  • Network signal works ok



  • I found none. You let me know if you find any.


P.S. Google Apps (GAPPS) added are "pico" version. (This rom already comes with the google play store, but if by some odd reason you uninstall it, here is the correct version for you to download and reinstall).


All the credits for porting these roms, go out to Septian Aditya​.

      I don't get any lagging at all. It sometimes hangs playing subway surfers.

      But that's all. Aside from the obvious bugs I mention in the post. 

      It's a developing ROM, I guess. But a fair aproximation of what LL5.1 is.

      The real one. Not some lame themed KitKat.

    It's a very good ROM, but I really need the camera, any fix for the camera not working?

      So far… No joy. I have tried other facsimiles but can't seem to find the right firmware for the camera. OTG is now working though.
      Plus I have found some gapps for this version. Check it out above.

    This Lollipop 5.1.1 works great now. Battery drain is almost non-existent.

    Comparing to Pandemic rom, I see a 30% save on energy (not kidding).

    So, in Pandemic rom with 3,5G and wifi on I get a 16h usable, max.

    With this Lollipop Rom with both 3,5G and Wifi on I get a full day! 

    Take that you big banana!

      yes ' I follow the instructions .

      I didnt get the gApps issue- is it includes in the installations or not? the device after the first rom installaition ask me to log in into my google acount – but it doesn't sync nothing and after installing the second rom the cammera stopped working

    I'm only sorry I'm on limited inernet bandwith, or I'd cook up a video and show you that everything works great on my Gionee Elife E7 Mini.
