RELEASE for S3 Mini
CyanogenMod 12.1

New stable release (20151114) 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)!

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.


  • CM sources updated to latest version
  • recreated whole device sources (due to buildserver crash, but at least we’ve clean sources ;-))
  • resolved issues with Settings app
  • experimental simcard failure (exists only for a few providers in the world) fix
  • Odin package update


  • RIL (phone/SMS/3G)
  • audio (both speakers/headphones/microphone)
  • Wi-fi
  • Bluetooth 4.0 with LE support A2DP
  • GPS/Glonass/A-GPS
  • sensors
  • compass
  • camera (taking photos and videos)
  • video playing
  • 2D/3D HW Acceleration
  • all native tethers (Wifi/BT/USB)
  • Google Play
  • CPU sleep mode
  • MTP
  • ADB
  • no tearing
  • tripple buffering
  • external storage
  • f2fs filesystem support
  • offline charging


  • video taken by stock camera app is green, but some apps like Camu taking correct videos without any issues
  • 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 😉

If somehow you’ll find a bug, use our bugtracker if you want to report it.

    it´s possible to find this update on “about phone —–> update system , like normal android updates (without format android) ? I have the release from 29th October from cm12.1.

  • Michael says:

    Please, let it be a good version 😉

  • Tessa says:

    Nearly a year, but it is not finish. Not better

  • Tavo says:

    Error to import my contacs from sincard!! Do not are!

  • ZyTriX says:

    Thanks Nova 🙂
    Screen Recording doesn’t work,
    I can’t install Minecraft,
    The Wifi – symbol is missing in the status bar when no WiFi connection is available.

    Sorry for my Bad english 😉

  • Mike says:

    Do my eyes deceive me or do I see a fix for proper SIM usage? If that’s the case, wow, Nova would be the first to have that function for custom ROMs outside of Jellybean. Good work! Lets just hope Vodafone is among the lot of fixes.

    Other than that, any stagefright issues?

    • Samuel says:

      Vodafone was also working before this realease

      • Mike says:

        I’m not talking about being about to credit your SIM, send and receive texts and calls. I’m talking about read/ write functions and being able to access the toolkit without the use of a SIM pin.

  • Emankcin says:

    Do someone use a Samsung Gear Fit? Does it work with the s3 mini and with CM12.1?

  • Rui says:

    it´s possible to update the previous version to this version by “about phone —-> update system” or I need to overwrite the previous version ??

  • martin says:

    nice, fast and smooth! (Y)

  • Caesar Montes says:


    Thanks for continuining work at this, but, why work with Cyanogenmod while CarbonROM is much more than CM … ?

    Last CarbonROM is very bugged, please, check it out and update it! Could be very nice to our old S3 Minis! 😀

  • Kimji Santos says:

    cool .. nice nova 🙂 i love this one :)) thanks to the developers .. now i can settle only one phone like ever before xD ..

  • Kimji Santos says:

    what about recording videos with green playback ?? is it fix by next update ??

  • Danovnzla says:

    I’m still can’t change the processor governor’s. This is a latest release problem.

  • AiVeN says:

    Very nice ! Thank you very much,working great!

  • Mike says:

    So any stagefright issues or what? Also I haven’t found an article anywhere on the video recording issue and why it hasn’t been fix yet. What I have seen is that’s it’s a drivers/libs problem and am wondering why no one has gotten it to work yet with porting drivers from an earlier Android version.

  • Dominik says:

    Works great, but why can’t move apps to sd? Or what is problem with facebook that fb cannot be installed

  • Bob says:

    In settings – Performance – Processor changing CPU governor wont work. Its been already for a long time like this.

  • YoCool says:

    Everything works smooth and stable.
    Tested all the functions for a normal user.
    BT pairing/play music, Flashlight, Music, Camera (photo), Clock, Alarm, Sound Recording.
    Nothing hangs, no errors.
    No battery draining.

    The only thing i miss, is the video recording function.
    Can’t find a good working app that works smooth or give green movies.
    That’s the only thing that made me always wait to update to CM12.1.
    But I have 2 Galaxy S3 mini’s, so for work phone, it isn’t a problem.

    Good work!
    Hope the video will fixed one day…

  • misanek1 says:

    Clock app is crashing after changing alarm tone to a song. When I select the track, clock app immediately crashes and alarm tone will not change.

    Offline charging shows only black screen after update from 7.10.2015. There is just loading wheel and then black screen. Until then there was battery charging indicator.

    Chrome and Firefox are crashing when page is resource-hungry, sometimes just for no reason.

    Random unlocks in my pocket (thank you Samsung for HW home button). MIUI has very useful function that deactivates touchscreen when proximity sensor detects object nearby.

    After 29.10. update phone is subjectively more laggy than before (this is probably HW issue – this phone is so old). Opening whichever app takes more than 30 seconds, I have to keep touching display to keep it from locking. When the phone locks and I unlock it, locking screen is creating itself for another 10 seconds 🙁

    Random (but probably delayed) touches. Sometimes when I take my phone out of my pocket, it will dial random people from my contact list. Sometimes I can’t cancel my call, because there is some stuck touch command in right portion of screen.

    Majority of this is not your fault and I have to say, that this ROM is much better than stock. Thank you Novafusion, I love your work.

  • Tony Sanchez says:

    I cant use mobile data D: need help plz

  • mario says:

    I’m still can’t install any APPs from SD card. The Install begin but the button for install do not work.

  • Sonny101 says:

    These are my main problems with Cyanogenmod 12.1:
    1) Google Play keeps randomly crashing (even when it’s not opened)
    2) The internal memory keeps getting full even though I only use less than 500 MB (it shows me I am using 4 GB while all my apps + files take together only 500 MB) [yes, I do use many cache cleaner apps]
    3) The UI sometimes crashes and freezes
    4) Apps run much smoother in Cyanogenmod 11 than in CM 12.1
    5) Facebook doesn’t work again
    6) Videos are laggy and buggy, they like to freeze etc.

    That’s about it for me, I hope the 2), 4) and 5), maybe 6) will be fixed asap

    • DarkDawn says:

      I don´t have any of those problems. Phone runs smooth and (with a new one) battery, with voice calls and wifi on, battery last +22hrs and still 20% of charge.

    • Sky says:

      About issue 2, I was getting the same thing, it turns out cached data was the culprit (at least in my case). It was taking up more than 1.5 gb. Go to Storage and click ‘cached data’ and just clear it if you see it using a huge amount of space.

    • David Polly says:

      Clean de Dalvik Cache using the twrp

    • Mathew Da Costa says:

      With all of them except 6) you won’t get these fixed within CM 12.1 until someone else creates their own build tree from golden-guy’s OmniROM tree. Until then, use CM11 (or OmniROM if you really want Lollipop, though it’s not perfect).

      • Sonny101 says:

        Could you tell me how do I get omnirom lollipop?
        I’ve been searching but I’ve only found omnirom 4.4.4 and on their site, there is no sign of Samsung Galaxy S3 Mini…

  • Junior says:

    Ever since i’ve moved to cm12 ,i cannot seem to move apps to SD card. When i attempt to,it just says “Not enough memory on SD card” whereas its an 8GB which is tons of space, is this a common problem or is it just mine? *Installing the latest update at the moment,really hope the Sim Card issue is fixed

  • MASC says:

    I can´t install Facebook!!

    • Sonny101 says:

      download Facebook Lite (that works also from Google Play)
      download Facebook from any other app like Apptoide / 1Mobile etc., or download .apk file of it and install it on your own
      it only has problem to install it directly from Google Play

  • M says:

    I am wondering where I can find the source for ROM?

    The link at the top of the page leads to Github, but there are no recent changes in the repositories. I think it would be interesting to follow development and as a newcomer it would increase my trust in the developers and the quality of the ROM.

  • Sonny says:

    Where can I find their bugtracker?

  • Denny Crane says:

    Did someone check md5? I always get a failure message.

  • rtx04 says:

    How can I install XPosed on CM12.1? I tried but the phone stuck in the bootloop :/

  • Mr.Mini says:

    Some apps can not find GPS, please check it. Other features works fine, good work, thanx.

  • androgamerzz says:

    I can’t install Minecraft PE

  • fred says:

    Will radio (ultra short wave – not internet radio application) be part of of the project ?
    Is there a recommended radio apk existing like the one provided by Samsung ?
    Thanks for the work you did in the past and please continue in improvements.

  • prabeesh ps says:


  • Johnie says:

    I dont find settings for whisher push on privacy setting any more… 🙁

    Is that an feature or a bug?

  • rairafaelss says:

    Snapchat camera doesn’t work. It is an error of the green camera bug (sorry my bad English)

  • Alex says:

    When I enable WiFi hotspot device becomes very very slow and it takes around 5 minutes to switch to hotspot mode. Switching off to normal also takes time. sometimes crashes. The same was in CM11. Can you please look at it? I have GT-I8190.

  • David Polly says:

    How can I use Wi-Fi Direct? I don’t wanna install any app like xender or similar.

    • Mathew Da Costa says:

      WiFi Direct seems to be broken in every version of Lollipop I’ve tried. Just out of interest, what were you going to use WiFi Direct for?

  • PedrokZ says:

    snapchat works?

  • Luigi Russo says:

    Hi, I’m blind user. I have been installed CM 12.1 on my Samsung Galaxy S3 Mini and GApps full. ROM works correctly, but when I enable Talkback screen reader the phone becomes very slow and unusable. I tried to use it on Note 3 of a my friend with CM 12.1 ROM and works correctly. I need use this software to use phone… Thanks for your collaboration.

  • What about NFC? Please make it working. Best Rom! Thank you bro!

  • Hugo says:

    Please, add the proper button backlight support.
    Thank’s Nova! Great workk!!

  • What about NFC? I cant activate it. But thank you for this beautifull fast Rom which is the best for Android.

  • z1rqdym says:

    This release is horroble! RAM usage is really bad. The older releases of cm12.1 are more stable then this latest one. Please check the RAM usage, my phone freeze even when i only use settings and apps page. İ did totaly wipe before installation.

    • Ryan says:

      in twrp

      convert data and cache to f2fs

      you will lose your apps – you will lose your data and you will lose what is on your phone storage

      but it might fix your problem

      and depends on what apps you have

      and don’t forget it is a miracle to even have kitkat let alone lollipop and maybe marshmallow

  • fendi mustafa says:

    [BUG] gallery crashed when opening .gif file.

  • Inish says:

    Clock App crushes seconds after I turn on my phone, so no clock no alarm etc. I`m forced to install app to this work.

  • Hugo says:

    I can not install the facebook the Play Store.
    Thx Nova!

  • powerwave says:

    By enabling Power saving mode, Battery saver, screen brightness is “increased”. Also there is no regular way to reduce the brightness except disabling Power saving mode again. Is there any easy fix for this?

  • nimte says:

    Please I8200L version! I really want android lollipop on my S3 Mini Value Edition ;/ :v

  • CH says:

    Are you working on Andriod 6.0? For Galaxy S3 Mini?

  • capcomx9 says:

    Battery drain fast x.x

  • Florian K. says:

    What about a CM13 alpha?
    I guess, It wouldn’t work smooth or bugfree on the S3 mini, just proof of concept

  • gilgamezh says:

    Hi, my power button is broken.

    How can I make the phone allways turn on when I plug the charger?


  • Atinisikenkovboy says:

  • tony laynes says:

  • Gabbia says:

    AUDIOFX don’t work with TUNEIN RADIO

  • Gabbia says:

    Thanks Nova
    Phone application, call history…. Some calls are registered as UNKNOWN

  • JK says:

    Thanks Nova.

    Can i ask what app to use for taking videos other than Camu?

  • Joseph says:

    Not sure why my question have been removed…..
    Is there any app other than Camu for taking the videos??? Camu videos are very laggy.

  • Bryāń says:

    Cm13 plis

  • GualbertoB says:

    Improve video errors please. And radio!

  • David Polly says:

    I use Camu to record my videos, but when I record a video, the app gets laggy, and the video has recorded laggy too.

  • oscerus says:

    please to update link to download the 12.1

  • Hi android 6.0.1 marshmallow rom please ?? 🙂

  • Mike says:

    OK FYI: Stop asking for Marshmallow. It’s pointless from a developer perspective to work on later editions of Android until they have fixed the major issues with previous ones, such as the recording issue with Lollipop. Otherwise developers end up backlogged and still trying to fix driver issues that weren’t included by the manufacturer in later releases too.

    So, stop asking!

  • Kaam24 says:

    Any app to récord vídeo? Camu is so laggy and vivavideo 5 mins or $$$ .
    Anyone knows a good one?

  • Bernhard says:

    Novafusion, thank you for making CM available on S3 mini/golden.

    Has anyone managed to “Encrypt Phone”?

    Doesn’t work for me, even after reducing the size of /data down to 1239028 blocks (to make space for the crypto footer).

  • Antonio says:

    sometimes it suddendly reboots without a reason. What can I do ?

    • Asdf says:

      I have exactly the same problem and haven’t yet figured what’s causing it. Any advice how I could start debugging it?

  • Sky says:

    I’m just curious, what’s the best lollipop Nova build you’ve tried so far? I’m using the July 23rd 2015 build, it’s the one I’m most happy with, everything works perfect so far, no problems/bugs whatsoever. I tried a few versions (not all) after that one but in the end reverted back this build. What about you guys?

  • madapaka says:

    it crashes my phone so many bugs not stable at all 🙁

  • emre says:

    new release,please..

  • cadide says:

    @Sky – running fine on 20150923 – no issues so far beside the well known video bug …

    Thx Nova

  • Dani says:

    It smells cm13….. 😀

  • Tuğrul says:

    A CM13 release would be nice 😀

  • Gerus says:

    For everyone who can’t install a choosen app: go to the shell and set the install location with the pm-command to internal(1) then it should work(for me it works verry well)
    If i maked fails using english sorry it’s not my first language

  • cachirro says:

    tried several video recording apps, all end up recording green stuff or garbage pixels

  • tux8080 says:


    so I am not the only one with this problem!

    I also reduced the size of the FS to have enough space for the crypto footer and even tried to enable the encryption with the wipe option via the debug console, but did not succeed. If anyone knows how to do the trick – please let me know! I would really appreciate this!

    Thanks in advance! 😉

  • Guillermo Burlando says:

  • z1rqdym says:

  • Dimasegitiga says:

  • Roland says:

    Has anyone else have this problem (I’m not sure if this is related to this version):

    When I’m on 2G and I want to switch to 3G mobile data, it stays on 2G and the ‘prefered network’ says 3G (currently: 2G). I can only switch to 3G when Wifi is connected.

  • Yunus says:

    Hey guys, I just flashed new release and it’s fine, but when I flashed gapps and try to set up my google account it immediately stops and shows an error message says “google play services has stopped”.
    Also, i wiped data and cache and dalvik cache. I try to do a clean install then, but it didn’t worked. Any ideas?

    Thanks a lot for your work!

    I have an issue that my external sdcard is not recognized. It’s just not mounted. Worked well with stock ROM. Any idea how I could go about debugging this?

  • Hazzl says:

    Reformatting the sdcard with vfat worked. Strange. But thanks anyways.
