RELEASE for S3 Mini
CyanogenMod 12.1

New stable release (20150404) of CM12.1 for S3 Mini is available!

Please, test it and report any bugs!

For flashing Lollipop, we recommend you to install our TWRP recovery (available on Download page)!

If you want to say thanks by donating us using PayPal, feel free 😉

Do full backup before installation and wipe data/cache (factory reset) after installation if you don’t updating from older CM12.0 release.

You need to perform a wipe if you’re migrating from software different than CM12.0!

You can get it on our DOWNLOAD page.


  • CM12.1 sources update
  • fixed booting issues – now it’s working as it should!
  • Odin package updated

  • Bluetooth 4.0 with LE support A2DP
  • GPS/Glonass/A-GPS
  • sensors

  • ADB
  • no tearing

  • less than 2% of users are reporting issues with mobile data – just add new APN manually with settings proper for your provider and apply it to make 3G working

I’d be glad, if you shared links to our download page, instead of direct links to download.
Also would be great, if you wouldn’t create the mirrors 😉

  • Nikola says:

    Hello all, I’m stuck… (well what’s new… :]) -having flashed and rooted my i8910 I have tried to install latest Rom (CG_12.1). Got it all; ROM, gapps, TWRP ( -newer releases just wont accept. Says all’s well but when reboot into recovery same build No. remains - OK… When I boot to TWRP anyway, and choose to wipe ALL partitions to f2fs (/system, /Data & /cache) all’s fine again, until i actually initiate flashing with latest ROM (Lolipop 5.1.1.). Then i get;

    detected ext2 for /dev/block/mmcblk0p22 and just after; detected ext4 for /dev/block/mmcblk0p22.

    I conclude that the partition /system gets reformatted back to ext4… -Why? Is there a solution? If so please help, since my Mini drags worse than a snail and it lifts my nerves unnecessary… 🙂
    Thanx in advance and all the best!
    If there is already description to my question please direct me there. THX! 😀

    Great job and always good to highlight the commitment and effort- this crowd .

    – Some applications forthe working.

    – Call Application and slow and stable most of the time .

    – I still can not move applications to the SD card .

    – Most annoying problems appear on screen transitions and rolls applications texts web pages . Apparently not the timing, as in games of PCs when the v- synic this off.

  • anzharip says:

    After a day of using this ROM:
    – Navigation and opening app significantly smoother than previous release 20150331. But I see there’s some kind of artifact on animation.
    – Camera working normally, pic taken not green.
    – Mobile data is working fine. No manual configuration needed.

  • Spirou59 says:

    Looks fine for me. Still the bug of power off charging (phone is powering on). Installed on 201504003 without Wipe. All settings remained. WiFi works better. error messages: play store service stopped, norton security stopped. play store doesn’t work. Maybe need installing GApp again? That’s all for now.

  • uso says:

    – Flashlight Long on-time.
    – Bug with Flashlight icon. Sometimes it desappears when toggle…
    – No EAP-SIM
    – Calculator doesn’t work very well
    – slower than previous releases
    – Wave display when scrolling

    To Nova Team: could you update the link to dowload GAPPS, please ?
    It is broken…

    • Joheny says:

  • Serkan Vardar says:

  • ebby says:

    Hey 🙂 Used CM11 and wanted to try this out… My phone aborts the installation in Recovery mode

    Warning: detected filesystem ext4 for /dev/block/mmcbl0p22
    detected filesystem ext4 for /dev/block/mmcbl0p22

    E: Error in /external_sd/cm12.1_golden.nova.20150404.zip
    (Status 7)
    Installation aborted.

    • Marcos says:

      jjust in case , try to format the file system of your phone to ext4 , maybe you are using f2fs and is not fully supported on cm12, happend to me once

      • ebby says:

        Thanks 🙂 I was able to install it now, just installed an up-to-date TWRP recovery, had some old CWM installed….But something must have gone wrong with it…. Now the Samsung logo on startup is distorted, can’t even read it or anything, just looks like a multi-colored landscape screen or something like that. :/ The screen after that looks fine, boots as it should and no other screen problems, but this bugs me…

  • Chinedu says:

    When will support of I8200 s3 mini come out?

  • Acabo de instalar la version 20150404 asi que pronto comentare mi experiencia. Use durante cerca de un mes OmniROM 5.1 y la verdad me gusto pero volvi. Me gustaria que puedan implementar AMBIENT DISPLAY.

  • icowin92 says:

    Must I install Gapps 5.1 for install this cm12.1?

  • hello..
    the msg cann’t send with messeger aplication, but when i try to use hangouts its work.
    why i cann’t use messenger aplication as default msg ?

  • G says:

    Unfortunately, this release is unusable…
    1. No signal
    2. A LOT messages about crashed apps
    But thank you for your work!

    • Nosfi says:

      Install the newest Google Apps Package. That will stopp the crashing.
      The signal was also gone on my handy in the beginning. It came back after a while

  • yasin says:

    Maybe you want to try blackmart market app instead of google play. All the expensive apps are free in blackmart. And it works with all android releases. Just try. You can find it easily

  • j says:

    Hi all, sorry this may sound like a really stupid question but it states on this page to wipe data/cache “after” installation if updating from older release. Surely this should be done prior to installing right, with tne order being backup, wipe data/cache, install 12.1 and Gapps? Sorry, just a minor detail but just want to check…

  • Darryl says:

    Thanks a lot Nova for ur hardwork but my screen is kinda waving. Is it just my phone or does anybody else also have this problem.

    Will be looking forward for the fix of 3g.Keep up the good work

  • Richard says:

    hi, thanks… Great job . I found two bugs:

    * can’t move apps to sd card
    * can’t save photos from camera in sd card

  • bomilkar says:

    12.1 2015.04.04 for S3 mini works better than the most recent 5.0 releases.
    I installed it together with the PA Gaaps 5.1 micro package.
    After 24h of testing stability and battery are both as expected.
    Thanks a lot! Keep up the excellent work.

  • I just installed the version 20150404 so soon tell you my experience. Use for about a month OmniROM 5.1 and I really like but turned. I would like to be implemented AMBIENT DISPLAY.

  • Dennis says:
