RELEASE for S3 Mini
CyanogenMod 12.1

New stable release (20151029) 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.

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

    I have problem with all versions since 12th September that battery discharges quickly especially when i’m listening to music and standby regime. Hope in this realise it fixed.

    • David Polly says:

      Disable the cLock widget, and add DashClock.

    • Mike says:

      Dude do you know how to even tweak? Muck around with the performance settings for different results.

      What about live wallpapers?

      Do you have all sensors on?

      What apps do you keep active? They all use memory and CPU cycles

      Those are the questions you need to be asking yourself.

      So, everyone, stop asking dumb, timewasting questions.

      • Nicholas says:

        Yes, I know many ways how to save battery life, but problem is’t in this. When I’m using version of 1th September battery uses in standby regime only 2-4% for 5-6 hours but when I’m using next versions it uses 2% during the time I’m writing this reply. And in each of this versions I used same apps, so problem is’t in them but in realises.

        • Mike says:

          So what’s the problem then? Sound like this version has better battery improvements over the last.

          I wouldn’t recommend upgrading every version, either, doesn’t always fix previous problems. Try a fresh install…

          • KiwiTec says:

            Sometimes your device doesn’t enter the sleep mode. Caused by a google app or a system app. In my case a simple reboot helped.

    • I just want to comment . Apart from the failure of the camera , the main problem of this operating system is the data connection. As much as is done manually configuring the APN , the data signal is fickle and unstable. Of course grateful and effort for you is valued. Best regards.

  • Nik says:

    Great job Nova 😉 This release is stable and perfect! But in this time you work only to correct bug and update sources and it’s good…but when you apply big changes to cm12.1 release, as the camera fix and the natively lollipop-way offline charging with the animation? Please Nova, i want from you a new milestone release! You must work hard to make cm12.1 absolutely perfect and without problem because you also have to work to marshmallow cm13 release!
    Sorry for my bad english.

  • Tuğrul says:

    We want Android 6.0 Marshmallow you doing great!

  • ZyTriX says:

    Please fix the Camara Problem… 🙂

  • Alejandro says:

    my Bugs

    – Offline charging, no works.

    – Sometimes, I have to install APP’s errors. In particular, Facebook; takes to settle, then automatically restarts.

    – Its battery pack seems to finish very fast.

    – You give me, automatic restarts, on some occasions.

    • Mike says:

      How do you know offline charging doesn’t work? Have you tried checking the battery percentage while on?

      Have you cleaned the dalvik/cache lately? What about a fresh install?

      • Alejandro says:

        Yes, Last 4 Room upgrades , it does not work, offline charging.

        Yes, if I cleaned the dalvik/cache. Even I did a wipe; but the problem persists

        To you if it works, offline charging ?

        • Alejandro says:

          I applied through the rom, TWRP
          You think that if applied with Odin, Run?

          • Ryan says:

            offline charging does work – it just doesn’t have an animation
            at night turn your lights off – make sure room is fully black

            turn phone off
            plug charger in
            wait until white circle goes away
            then wait 5-7 seconds
            then tap power button – you should phone should slightly up

            i’ll make a video on it

            but…offline charging charges reallly slow anyway

  • Hugo says:

    Heey, the volume button doesn’t turn with the screen orientation. Thx Nova, Great Work!

  • ricky says:

  • Rodrigo says:

    I have a error in Whatsapp aplication: In VoIP Call there is no sound, i can´t hear the other.

  • villagermd says:

    Is This ROM Compatible with GT-I8200N?

  • Gringo says:

    GPS is not working with “maps.me”

    • Mike says:

      Have you tried any 3rd party apps to fix calibration from the “Play Store”?

      • Robbe says:

        Hi Mike, which app did you use to calibrate the GPS?
        Thanks for your help

        • Mike says:

          I’m not saying it will work, but maybe it’s worth a shot before reporting it. It seems like custom ROMs have a huge issue with profiling, weather it be the battery, GPS fixing, etc.

          I have only used one app on KitKat to date for the sake of experimentation and that is: “GPU Status”. I didn’t notice any changes to my GPS fixing (probably because there were no issue anyway) but it might work with “Lollipop”.

          If that doesn’t work, try a few others. If they don’t work, then it can be assumed to be ROM issue on a deeper level.

        • Mike says:

          So it’s fixed?

  • Robbe says:

    Good day:
    1- Superuser does not appear in settings even if it is activated in Developer Options.
    2- Not able to change the CPU governor, it is stock in interactive, I/O scheduler can be changed.
    Thanks Nova

    • Robbe says:

      Offline charge is not working

      • Mike says:

        Are you sure about that? It works just doesn’t indicate that it does. To get it to show the battery status I read that you have to change one of the file systems to f2fs, I think it’s data.

        • Robbe says:

          Thanks Mike it is not a big deal cause I always charge the cell on. I was with omni 5.1.1 until yesterday that I wanted to give a chance to CM but I see that they include always something new without fixing the old issues. The battery duration is as always pretty short, that is why I reported that is not possible to change the CPU governor, I wanted to use the combination of ondemand and noop but the governor is stuck in interactive. I hope they will fix this bug

    • Ryan says:

      1) superuser has never been in settings

      2) nova is aware of this – turns out it is a change to cyangenmod by the official cyanogen team

  • yusdani says:

    what about the videos in green when you try to film with the camera ????

  • JadeRivera says:

    Sir my phone’s Menu and Back button not responding but they light when i open my phone everytime i reboot it. I cant find any solutions for now please help me thanks.

  • riyad chokri says:

    is there a way to add charging animation while the phone is off

  • S3miniUser says:

    I use your ROMs for S3 mini since 10.1. and cannot complain about anything. It works perfectly in all cases i use my mobile (except current cam bug). Thank you very much for your great work!

  • Noldy Christian says:

    Use Rom Toolbox to change the governor.

  • Max says:

    Hi, I have an issue with microphone, expecially with Google Now installed. If Now is running i can’t use microphone in other application like Whatsapp Vocal message, shazaa or other applications that need microphone. When i try to uninstall Now, the microphone is avaible for the other application

    • Enriquelap20 says:

      I also had this problem, it only happens when you’re using “OK Google” detection on every screen, you could disable hotword detection and it should work fine, but I would like to know if there is a fix, anyone knows about anything?

    • rairafaelss says:

      You just have to disable the “Ok, Google” funcion on every screen. Go to the Google Settings and you will find it.

  • tux8080 says:


    thanks for your work, novafusion!

    Did anyone manage to successfully enable the disk encryption? If yes – what’s the trick? My S3mini always aborts the encryption after a few secs and performs a (quick) restart. Is this a common problem?
    It used to work with CM11.

    Thanks in advance for your help! 😉

  • Sakipa says:

    Excuse me but when the green video problem it will solved ? i need to know please

  • SPKJ says:

    Nice job novafusion 😛 😉 🙂

  • Dominik says:

  • Bems_ says:

    Wifi is not working. I hear issue about “wifi drops” on cm12.1
    Can somebody help me how to fix it.

  • kakaouskia says:

    Has anyone ever tested the FM radio with this? Does it work?

    The person that is going to be using the phone with this update cares only about:

    – Calls / SMS
    – Camera / Video
    – Wifi (for app updates)
    – FM Radio
    – Alarm clock

    From what I can see, this CM version covers all, only the radio is not mentioned.

    Oh, and thank you to the developers for their hard work!

  • Bora says:

    Low call please fix it.

  • Nik says:

    I’ve tested this release and it’s good but I have problems with youtube (some parts of videos are green) and the phone…please fix them! 🙁
    Sorry for my bad english

    • SPKJ says:

      You’re italian?

      • Nik says:

        Yes, I am… Why?

        • SPKJ says:

          Anche io sono italianoooo 🙂

          • Nik says:

            Ahahahah 🙂 grande!!!

          • Elvitek says:

            Se è per questo anch’io lo sono 😀 Ragazzi ma voi avete il problema che non scarica Facebook e se lo installa a forza cancellando le cache del Play Store, quando si riavvia il telefono c’è sempre il caricamento dell “ottimizzazione applicazione” ? Lo stesso caricamento di quando flashi una rom o le gapps… 2 palle 🙁

      • SPKJ says:

        Elvitek anche io avevo questo problema che quando riavvi ti esce semore ottimizzazione delle app 1 di 3 , ho risolto in questo modo:ho scaricato la rom cyanogenmod 11 sempre della novafusion, poi ho fatto il wipe base del telefono,poi ho installato la cm11 poi ho acceso il telefono,poi ho fatto di nuovo il wipe, poi ho reistallato la cm12.1(ultima versione disponibile,e adesso non mi sta dando più problemi 🙂
        Spero di essere stato utile 🙂 poi fammi sapere se sei riuscito a sistemare questo problema;-)

        • SPKJ says:

          ragazzi secondo me il team della novafusion sta sfornando una freschissima rom cyanogenmod 13, voi che ne pensate? 🙂
          non vedo l’ora di provarla 😉 hihihihihihihihihi 🙂

          • Nik says:

            É quello che penso anche io… non può passare così tanto tempo per una semplice release… qua si stanno facendo grandi preparativi!! 😉

        • Elvitek says:

          Può darsi che si risolva in questo modo ma per rimettere tutta la mia roba tra file e app ci metto 2 o 3 giorni e non ho voglia di rifare tutto quanto…. Aspetto che cala la Madonna e che mi si aggiusta da solo ahahah

          • SPKJ says:

            haahaahahahaha XD
            ok eviltek
            puoi aspettare qunato vuoi ma non si aggiusta da solo,a me per mesi lo faceva haahahaha ma non si è mai sisemato XD
            L’unica soluzione è quella che ti ho detto, ma credo che puoi sopravvivere a un paio di minuti di avvio rispetto a due giorni per reinstallare le app hahahahahahaha XD
            😉 🙂 😉

          • Elvitek says:

            Si si, infatti aspetto, anche se così Facebook non mi si aggiorna… Mo vedrò con la nuova versuone della rom, sempre se uscirà xD Ciao SPKJ 😉

  • Nik says:

    Great job Nova 😉 This release is stable and perfect! But in this time you work only to correct bug and update sources and it’s good…but when you apply big changes to cm12.1 release, as the camera fix and the natively lollipop-way offline charging with the animation?

    Hi, this is the third update I can’t apply on my phone because it bootloops everytime and I can’t get it to work. The last one I was able to use was 20151007. Do any of you know what’s happening or how to solve it? thanks.

  • G1r3D says:

    Back and menu key not working, can’t fix it and lost stock backup. help please.

  • Ralf says:

    Thanks for the Release, its working great! Besides the green video issue the swype function of the AOSP keyboard wasn’t working. Coping the libjni_latinimegoogle.so file to the System\lib folder and a reboot fixed the problem.

  • don says:

    thanks Nova, how to change system to f2fs?
    it always revert back to ext4, i succeded change data and cache but not the system
    i use both NF TWRP and Andi’s TWRP but no luck

    • Johnie says:

      On Kitkat where was a separate install routine to use f2f on system partition. This routine are not implement on CM 12.x recovery images… so the partition will always formatted in ext4.

    • M Juki says:

      you need to modify updater-script to prevent formatting /system to ext4.

      • M Juki says:

        EDIT: it’s not working. my phone bootloop. but i think ext4 is enough since /system is read only and not much write operation.

  • CyberStorm says:

    why can’t I add to the black list number is +78055555302?

    Thanks Nova for the rom 🙂

  • Mambor3t@ says:

    Amazing job Nova!. Seriously, I really appreciate your effort for bringing to us this powerfull and stable release for our old S3 mini. However, the bug that really troubles me is that I cannot transfer apps from the internal memory to the SD card! Does anyone had the same problem?. Once again, thanks for the Lolipop!

  • Alexey says:

    •Battery charging error
    •Keyboard line touch error.
    I’m not speake english, sorry please.

  • NotATroll says:

    why is cm taking like 4gb of my system? and after installing 2gb gapps..i only have 2gb space left. plz try to compress the rom in the next update

  • Samuel says:

    Does someone tried Xposed? It isn’t working for me.

  • NotATroll says:

    u have to install it manually, it works tho

  • Will s-r says:

    I have installed this ROM recently on my S3 mini (GT-18190T) and i had a few problems. I had a stable ROM before this one from Novafusion and it worked perfectly with no issues at all. Then when i wanted to change my CPU speed from interactive to performance (as i had a power-bank so battery drainage wasn’t an issue).I used device control and after i found the settings for it in dev settings i used that. It worked fine until my phone started to crash. I updated my ROM to the next version that came out and i worked fine but now i couldn’t change the CPU speed at all. I tried using device control, it said it had changed it but at next boot-up, it reset to interactive. Then i thought i would try update again

    So now i am on this version(20151029) and i have even more problems. First Google play services started crashing all the time and i couldn’t use YouTube or Any Google services. It started to crash more frequently now, when the CPU usage goes up. So I decided to wipe and reset the ROM. It really didn’t change anything, other than the fact it doesn’t crash as much(but still crashes).

    Extra bug, In Google Now app, there are some glitches, idk if this is with gapps or with the ROM.

    So now im stuck, Please update and fix some of these or suggest something to me. I’m thinking of reverting down to a more stable version or going to cm 12 with Lollipop 5.0

    Could anyone suggest anything for me?

  • Bernd says:

    I installed 12.1 on my Galaxy S3 Mini – it is the first time ever I installed a custom ROM. So far it works fine except for the access to the SD card. It is shown in Settings/Memory with 29,7GB empty, but I can’t move apps to the card – the error message is “no space left on the card” (although it is empty). When I delete everything on the SD card using Settings/Memory, it shows 0B afterwards. What might be wrong? I tried formatting it using different file systems; I removed it and inserted it again; nothing seems to help. Maybe it is not mounted? How do I check/correct this? Any ideas?

  • _ANDROID says:

    I was talking with one developer and say the bug of the camera and he say me the problem of the camera is the kernel (True or false idk)

    • Ryan says:

      the kernel is the part which manages the drivers

      only Samsung has knowledge of how to make the drivers

      so yes it is a problem with the drivers inside the kernel which
      can be solved but can not be solved easily as samsung did not make any drivers for lollipop

      • _ANDROID says:

        My friend told me that developer to step with the original rom 12.1 cm several terminals but when they changed kernel arrangement but at least for s3 mini no stable kernel LP

  • Elvitek says:

    There is a bug in the rom where Facebook is not installed and an error that is the 504 and is, if you manage to install Facebook deleting the cache of the Play Store (sometimes it works and sometimes it does not, and if it works you install only if it resets itself from the smartphone), on every reboot is loading says “optimizing application 1 of 1” and lasts about 20 minutes each time.

    How can you solve? Thanks and sorry for my English.

  • haloxx says:


    I have tested my i8190N version in the recent months with different builds from Novafusion (e.g. 5.0, 5.1, 4.4). The GPS module did not work in any release. I tested it with Google Maps, GPS Status and Androsensor.
    I strictly kept the installation guides and also wiped cache and dalvik. Sometimes i wiped also system. I tried installation with TWRP Zip or Odin package. It never worked. I installed Open Gapps and without. With A-GPS update or with GPS fix patch did not work either.
    In all Samsung stock firmware the GPS module works perfect! Even without A-GPS download.
    I even installed other kernels and updated basebands. Still no function of GPS.
    In the CM rom Google Maps is only able to locate with WLAN and mobile network location but no GPS. So it has access to my location service.

    It seems that all releases miss the correct driver for the N version of S3 mini? Perhaps the N version has a different GPS hardware module?
    I really would like to use the great Novafusion CM releases but without GPS it is not possible. I already tried to search for this problem in google, other forums and XDA but no clue anywhere.
    Seems that not many have the N version and tested the GPS function.
    Does anybody have an idea how to solve it?
    Your help i greatly appreciated. Thank you in advance.

  • mastermontpe says:

    Very good job, but is not ROOT, why?

  • Jaime Tellez says:

    Hi all, first of all, thank you for the great job they have done. I have a problem that I hope you can help me, I have a SimCard Tigo in Colombia, with the rom stock phone me the generally recognized and to turn the data I work normally, but the switch to CM12, I get the R roaming next to the sign, and not let me go mobile data, until you activate the data roaming function, I do not spend this extra balance, but do not understand why I get roaimng being in my country, something that did not happen Stock rom, I thought it was the modem of the Rom, but the flash the rom stock, and as usual, some solution? Thanks in advance

    PDT. My model is the GALAXY S III mini – GT-I8190L

  • Dani says:

    Dead proyect?

  • Labestia says:

    make a overclocked kernel for this rom, but a optional download for new users. 😀

  • Nik says:

    Ok Mike…in short: there are some phones that already have a marshmallow rom (search in internet or watch some videos on youtube)… so I think (sources not completely reliable) also Nova team is working on marshmallow because if you remember the s3 mini was one of the first devices to have a lollipop rom

  • Nik says:

    There isn’t an official rom for our devices but if you remember the s3 mini was one of the first devices to have a lollipop rom. So I think the project isn’t dead but the team is working hard on marshmallow.

  • 6ak5 says:

    Say me please, how can i change sound of internal speaker??? too low sound of incoming calls, but when i call the sound volume is ok!?

  • 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 developer and the quality of the ROM.
