CM12 Android 5.0.2 Lollipop ROM for Galaxy S3!


For those of you who have been waiting for a Android 5.0.2 Lollipop ROM, there’s been many beta versions in the last few months.

If you own the GT-i9300 model, you are in luck as the Lollipop ROM runs near flawless with everything working out of the box. As for AT&T, T-Mobile, Sprint, or Verizon S3 users, you will also get pretty stable build except the camera/camcorder is not working. (You can get still photos working sorta with Open Camera app.) If this is a concern to you, you may want to wait out few more weeks for camera fix.

    • TK-Wings says:

      Yup, same here, my I747 does not have service either

    • mark814 says:

      I got everything running without problems, except, it drains my battery very fast. It will run completely dead after 16 hours of sitting. If I plays games or just generally play around with the phone it will go dead in about 6 hours.

  8. gus says:

    I have rooted I9300 with clocckwork mod receovery and Stock rom ver4.1.2 , is it ok to flash this rom following instructions as per video.



  9. john says:

    Installed succesfull, on GT-I9300, and working perfect. But I lost my root, (how to root on android 5.0.x ?)

  10. shaq says:

    thanks it worked but no baseband after flashing

  11. lollipop says:

    for t-mobile s3 (SGH-T999) d2lte or d2tmo this ROM is pretty stable. but no video recording. can take pictures. Im currently using this rom. but i will definitely switch to CM12 as soon as this rom is stable.

  12. Riley says:

    Installed lollipop on sprint s3. Works great. Will use as daily driver. Had to install open camera in order to take pictures. Still no video. Kitkat 4.4.4 liquidsmooth rom is my favorite.

  13. Alexandru says:

    Hi! i rooted my i9300 by “”
    I ll be able to install 5.0?

  14. fredo says:

    I successfully downloaded it on my T-Mobile s3 and the camera didn’t work and I didn’t have service.

  15. sochai says:

    Running this rom…Very smooth & stable..Flashed on GT-i9300…Only 1 thing is the problem..Battery life is not good to me..Others are great..Thanks Max for shared this rom

  16. DB says:

    I LOVED this ROM but like everyone I lost Data service. I followed the siggestion to flash the stock firmware and that fixed things… I then rooted and installed other custom ROMs and can’t get service on them now, even though I was using them before without issue’s. Any suggestions to get the service connecting again? I curently have liquidsmooth 4.4.4 running… I can make calls, get texts, connect to WiFi but no data service. I also tried to manually enter APN but it will not save?

  17. ezkay says:

    What about the Galaxy S3 LTE (GT i9305)? Is this ROM working for my phone too?

  18. Tantavevus says:

    Great work. I have an SPH L710. As you said, pretty stable, except camera.

    There is one other issue that I have found. I love the ViperFx audio mod. There is nothing like it. It does not work with any version of Lollipop. There is a procedure and downloadable fix out there intended for the Nexus, however it has worked occasionally on my S3.

    Since Viper is very popular in the Rooted Android community, it might be worth looking at.

    Thanks again for the great ROM.

  19. tal says:

    hi it works & its really looking awesome
    but its really really slow compared to 4.4.4 gummy
    is it possible?

  20. Othman says:

    can i please have another download link or maybe a torrent because the download progress stuck alot

  21. David says:

    Works so far perfectly on my GT-i9300

    • Gaurav says:

      I installed it on my GT-i9300 and it works almost fine. There are few issues though which i would like to mention. First its slow as compared to 4.4 Kitkat. Second it always uses Voice Boost to make or receive calls. I tried everything to switch off voice boost and it always say Voice Boost Off but it always uses Loudspeaker for call which sometimes makes it nearly impossible to take private calls when people around you. Third Casting on Chromecast option doesnt work finaly i got it worked by installing #mirror enabler app from Google Play. But i am enjoying this ROM !!

  22. Shahriar Arnob says:

    Had to update supersu to make it work on my Sprint-S3

  23. kyle says:

    it took away my root i dont know how but it did

    • Gaurav says:

      You can simply enable root easily by going to Settings — About Phone — Keep tapping Build Number until it says that Developer options are enabled for your Phone. Then goto Developer Options and Enable Root for App and ADB. πŸ™‚

  28. manzi says:

    Hello guys, here is my story…..

    have a GT-i9300 so i was on strock touchwiz 4.3 jelly bean, just because CM11 (4.4 kitkat) was draining my battery too muck, so decided to try 5.0 and everything is working great, i may say 100%, performance is incredible but still my battery drain very fast. any tip to fix this? i really love lollipop i don’t want to return to stock 4.3 which is laggy and ugly lol. so bref, any tip is welcome!!

    note: my battery is the original that came with the phone (too old) πŸ˜›

    • Gaurav says:

      It comes with built in Battery Saver option. You can enable that to save some juice. Moreover avoid App Circle & Live wallpaper. Moreover when your phone gets heated up; check for the app which is causing it and do a force stop. I Hope this helps..

    Fairly stable on Sprint S3, however lose root. Anyone else experiencing loss of root?

  37. robin says:

    man.. after a while it becomes slow as shit

  38. mario says:

    umm exactly how do i transfer it from my computer to my phone?

  39. Marco says:

    I went to the “Notification drawer”, “Select and order titles”, and I add “Performance”. But then the performance icon stuck at “Power Save” mode and cannot be changed, is there anyway I can change it?

    • GSG says:

      hey Marco , i wanted to ask you if you tried the rom provided by Max that is build v6.1 ? if so then are you having any problems with it , like apps are working good and can your phone reboot normally ?

      what happened was that i Tamaseks build v8.4 and apps force close in 20-30 secs
      then i tried v8.0 , everything was good and even the apps worked fine no lag too until i rebooted my phone and it got stuck in bootloop and i was unable to get into recovery and had to flash recovery again.

      I was thinking of installing this build and wanted to know how it is. And as for your question , you can change the battery performance from setting in battery though v8.4 / v8.0 didn’t have such problem.

      • Marco says:

        Yup I’ve got v6.1 installed and everything works fine except I can only use the pre-installed camera (tried google camera but then camera won’t be connected). Reboot is okay.
        Btw I went to the battery setting but it has only got the switch for battery saver, still couldn’t find anything like battery performance.

  40. GSG says:

    Anyone who has lost root , just search on google for the latest supersu and flash it from your recovery to get root.

  41. Marco says:

    One more question, how do I delete the local searches history??
    These are not the Google browser history but the phone local searches history.
    For example you get into “setting”, press the magnifier at the top right,
    type something and press enter, then the history is there and couldn’t delete it.

    After I installed the to my T-Mobile SGH-T999L, It works fine and looks good but I lose the LTE icon in the status bar. That mean I won’t get the LTE connection and only get 4g as the SGH-T999. Is there any customer Lollipop rom update for the SGH-T999L. Now on the web, I only find Lollipop rom for T999, not T999L.

    • Dave says:

      Following previous post, after I seee my T999l lose LTE connection with the cm12.1 and this was not I want. Then I downgrade back to the sock rom + root that I had backup before flashing the Now my phone LTE connection is back in life. This post is just for those who has SGH-T999L and want to flash cm12.1 need to be aware that you will lose LTE connection after flashing.

      I also want to mention that after I flash my Sprint S3 SPH-L710 bought from Freedompop with, when making call either with hangouts or Freedompop dailer, the receiver side will hear big echo sound can’t hear what the caller saying when the caller side in 3g area. Thus, I restore back to the FreedomPop rom that comes with the phone.
