Please, test it and report any bugs!

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.

    Thanks nova! This rom is getting better every single release!
    I can’t wait to see something like Aroma Installer so it’s more easy to me use f2fs and don’t have to change it every time I install an update of the rom.

  • How about its performance compared to CM11?

    • Robbe says:

      Felipe is more fun, I am already use it for dayly purpose.
      It has some problems yet but I like to be part of a developing proget. I always keep a complete backup of my last CM11 that I used in my SD card if I find too many problems. Wipe what I need to wipe and restor

  • vope says:

    Great work !

    As requested in the topic, here are my bugs

    – Bad French layouts
    – Bad French translation due to Cyanogenmod
    – BLN Control doesn’t work, due to Novafusion kernel, apparently
    – Flashlight Long on-time.
    – Flashlight crashes when toggle several times… it is impossible to switch it off and then the S3Mini must be rebooted
    – No EAP-SIM
    – Sometimes when I turn on the screen, the touch doesn’t work.
    – Battery drains so fast !

    other comments :
    – I didn’t test off-line charge.
    – faster than previous release 🙂

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

  • Thiago says:

    Good morning, folks.

  • Eduardo says:

    Hello everyone, I have a problem with all the updates of this rom cm12.1 , I can never move applications to the SD will not let me , either in CM12 . In other rom as CM11 if I can do it , and formatting fully my SD and as usual , try it with Link2SD nor can be , also remove and replace the SD nor unanswered , another problem is that will not let me install apk ‘s I downloaded browser or other page other than the Play Syore , when I try to install puts me ” application was not installed ” and activate the option is unknown sources and still the same . I hope someone can help me with both problems , sorry if something is not understood as they do not speak English , thank you.

    • AiVeN says:

      Hi,moving apps to SD is not working for now on CM12.1. For the installing of .apk you must enable root privilegies in developer settings then it should work.

  • Vince says:

    Excellent ROM, Waiting for Camera to fully work!

  • Berkant says:

    Please fix twitter and instagram video crashes. I cant watch and share videos on instagram

  • Robbe says:

    I get frequently that Exchange Services stopped working. I use the Email app for my hotmail account and POP account. Any suggestion why is happening? It never happened in CM11 with the same numbers of mail accounts.
    Thanks Nova if you have a turn around.

    • AiVeN says:

      Hmm try deleting email app cache and data in app manager. I am using email app too but it works good for me. O.o If problem persist try factory reset.

  • moloski says:

    Me parece que Android 5..ha traido muchos inconvenientes a sus desarrolladores. CM 11 aventaja.

    • Robbe says:

      Buenos días moloski, esta ROM ya esta bastante estable, la estoy usando diariamente y puedo decir que a parte lo del video con la aplicación propia que sale verde, la ROM tiene resultados ya muy satisfactorios. Ya deje de usar CM 11., pero mantengo siempre un respaldo completo de mi ultima instalación de CM11 por si algo pasa, pero hasta el momento, llevo 15 días con CM12.1 y esta ROM en especial esta muy estable.

  • moloski says:

    I think Android 5..ha brought many inconveniences to its developers. CM 11 leads.

  • ZONHAX Sx says:

    BUGS !.
    – 5 minutes to install the Facebook application and another 5 to install mesenger facebok.

    this release is fabulous, thank feel great progress gradually.

  • ZONHAX Sx says:

    realmente seria agradable y util el que al igual que en la CM 11 4.4.4 cuando tuvieras una notificacion !; que se prenideran los botones tactiles para poder saber que te llego algo !.
    +eso enserio serial algo fabuloso y util sin lugar a duda !.

    • Robbe says:

      Parece que el kernel de ellos todavía no lo acepta, me imagino que están tratando de estabilizar la ROM y luego atacaran ese problema, fíjate que lo del video les ha costado muchísimo ponerlo a funcionar. Ya por lo menos la carga con el celular apagado lo han logrado. Van mejorando rápidamente

  • San Nguyen says:

    Random crash and reboot. Fix it. Please

  • Atakan says:

    please fix the video(green) problem.
    thanks nova for works..

  • donnald says:

    random reboots, sometimes random shutdown (with almost full battery)

  • joao sa says:

    i really love how you still support this phone. recently i bought the OnePlus One and i gave the s3 mini to my mother(she isnt really into the recent tech) and i installed the kitkat(wich i think is the most stable right now and with less bugs) and i dont come to this website for a long time and you still bring updates and thats awesome even though i will not use them anymore but i loved them
    cheers maclaw or i mean now is novafusion

  • Mike says:

    Nice work. But if you can’t access all hardware modules, it’s not a complete OS. Just saying. 🙂

    • AiVeN says:

      What do you mean by “cant access all hardware module” ? 😀

      • Mike says:

        Try accessing your sim.

        • AiVeN says:

          Oh you are right,i dont known about this bug because i am not using any sim card options,I have contacts in phone. I tried to move one sms message on sim and when i checked it,it wasnt here.

        • Robbe says:

          Mike good morning just a question as curiosity, is your cell phone unlocked? Can you use sims from any carriers in the world?

          • Mike says:

            Everything about my S3 is factory straight out if the shop. So yes, unlocked.

            I know its a custom ROM issue because everything (and I mean everything) works on stock ROM.

  • Clannad1337 says:

    Good job novafusion YouTube does stop crashing while a video is starting

  • Daniela says:

    Ya no tiene el bug de las llamadas? Porque cuando me entraba una llamada de repente se cortaba y era muy molesto por eso regrese a CM11

    • Robbe says:

      Daniela ya esta bastante resuelto con esta ultima ROM no he tenido problemas de caídas de llamadas y el volumen de la llamada entrante ya esta arreglado

  • vope says:

    Why me bug report has been deleted ? !!

  • 1caves says:

    Hi all. I would just like to say i’m a newbie on all these rooting and modding of android. This website is topnotch in explaining and directing what to do. Thanks to you all, for helping me mod my S3 Mini rom from Android 4.1.2 to 4.3 without hassles, and I must say I’m loving it.

    What is the difference between Android 4.3 and 5.1. Is there a better performance or graphical difference? Will my S3 Mini handle it?

    • AiVeN says:

      Hello,yes there is a lot of differences between this two versions as in performance and as in graphics. This version of CM12.1 (5.1.1) is in development,with some minor bugs,but i am using it daily and i am happy with it 😀 I would recommend you the CM11 (4.4.4 KitKat) because that rom is very stable,but you can give a try to this one and then decide which one is better for you 😛

      • Eldeo says:

        Thanks will give it a go. Been on this Jellybean 4.3 for like two days and its just so much better than what i had. Thanks again! 🙂
        This question was probably asked before – how does a person upgrade the rom to Kitkat 4.4.4 without installing all my apps from Jellybean 4.3.
        I have clockworkmod, luckypatcher, superuser # installed. Do you somehow make a backup of the apps only? Any advice would be much appreciated.

        One last thing on Jellybean 4.3 you must try and make it possible to create a folder, or atleast try and make it possible for the user to rearrange the icons in drawer. I found a work around by moving all apps on to homescreen, and rerranging into organised folders on homescreen, and then hiding apps in drawer. But thanks again for your guys superb efforts for making a great Rom.

  • vope says:

    but it was posted, on yesterday… :-/

  • AlejandroVelasco says:

    The Camu app recorded without sound, can sombody help me or let me know about other app that can record with sound.

  • Philipp says:

    Guys your great, this Rom is nearly perfect. No random reboots or crashes.
    The only bugs are the green video and usb otg is not working for me 🙁 Also wifi takes longer to connect and is not as stable as in your AOKP 4.4.4 Rom (I’m not sure if that’s your fault)
    But your doing a really great job. Thanks a lot.

  • Tommy says:

    Press power off ans the screen flickers very short in white before it fades out.
    That looks not very smooth.
    Is it poasible to fix it?

    Battery is very stabile with less drain when phone is in standby
    But when screen in it sucks battery very much.
    My battery is New and original spare part

  • Taai says:

    Where can I get the original (stock) ROM? Internet is full of fake download pages… I guess it’s the “I8190XXAMG4 SEB BALTIC” that I need.

  • Oscar says:

    i have a problem with mail App. it give an error with the exchange services and synchronization with exchange account. I do not know if that problem is only in my divice i guess it is a problem with the server

    • Robbe says:

      Try to uncheck in settings of your account Download account and see if the error goes away.
      I did this and it worked for me.
      Let me know

      • oscar says:

        I tried but the error continue even i tried to setting my account by manual settings (no automatic) but it does not connect with the server also i installed the ROM one more time but the problem is still.

    facebook radom crash

  • Thiago says:

    In this version the only ones problems I witnessed were some reboots while wearing the device (all times using along with charger) and the launcher that sometimes stops responding and just go back to close the process. I will test the most current versions.
