About CyanogenMod (CM)

CyanogenMod is an alternative operating system intended to replace the one pre-installed on your smart phones and tablets. If you’ve got an older device that isn’t getting updates anymore, or if your device seems unusually slow, or maybe you’re sick of spyware, adware, and other unwanted garbage on your phone that you can’t remove… Maybe your device is missing features or has been otherwise artificially limited in functionality. Perhaps you just could use a boost in performance. Or maybe you’d like to be more confident that your operating system has included some of the latest bug fixes. If so, CyanogenMod might be for you.


  1. Root & Install Latest 3.0.2 TWRP Recovery in Samsung Galaxy S3 I9300
  2. Check the battery percentage of the phone, it should be at least 40%.
  3. This ROM is only for Galaxy S3 I9300. Please don’t try this on any other smartphones.
  4. Backup all your data: Contacts, Photos, Apps & other files. (Although you will not lose other files except contacts & Apps, but its better to be on the safer side)

Final words

To enable Root access, Enable developer options and look in Settings -> Developer options -> root access. Currently Doze doesn’t work in Galaxy S3 I9300 but the developers might fix this in future updates. If your camera crashes frequently, download Google Camera from Playstore, don’t use the Camera of GApps. To Fix Stock browsing crashing issues, You need to grant it permission to access storage in Settings -> Apps -> Browser -> Permissions. If you have any other issue, contact Cyanogenmod using the report feature. Hope you are enjoying Marshmallow in Galaxy S3 I9300. Peace!

  • Yeah, the old CM 13 was updated to CM 14. As the previous OS had few bugs & FCs, a new updated CM 14 was released.

  • Yaniv Ben-Malka

    The link to download CyangeonMod 13 ROM referes now to OS Version of ‘Lineage OS 14.1’.
    Does that means I am downloading CyanogenMod 14.1 instead?

    • Devs-Lab Staff

      You might have dirt flashed the ROM on TouchWiz rom. I would suggest you to install twrp recovery again & perform a complete system format from TWRP recovery. Now install this ROM.

  • Basim

    Hello, I just intalled CM13 in my I9300 that is SIII. Everything was fine until the setup came to customise,that is language selection.I couldnt click next bcz a lock symbol is coming up. Pls help me out. I am beginner 🙁

    • Devs-Lab Staff

      Might be a installation issue. You can install the ROM again.

  • Luke

    First time user with an S3 (i9300). Tried cyanogen 15/07/2016 nightly build with mini GApps So far appears to be working great, though I can’t find an FM Tuner like on the stock ROM. Not sure if this is cyanogen or gapps.. Liking what you’ve done so far otherwise. Cheers

  • Josh

    Hello there. Today I finally installed cyanogenmod and i have a problem with gapps. Im using cyanogen from 2016 July 08 and the same for gapps. When I’m opening Store, it goes white for a second and then it goes back to main screen. I need to install google services. Appreciate any help.

  • Julian

    Songs start lagging when I play them through my bluetooth speaker. I think it started after the cm-13.0-20160621-NIGHTLY update.

    • Devs-Lab Staff

      • Julian

        The previous version wasn’t very smooth, apps took forever to open.

    I have installed the CM13 with GAPPS 6 and when ever i am trying to use the Phone app (after dealing the number and when i click on call button) the system reboots…
    Any ideas?

    • Devs-Lab Staff

      Might be some old system files messing. Format system & install again.

      • Alehandro06

        I did already 3 times! Same result

  • Mcali

    I just followed all procedures.I Rooted & Installed Latest 2.8.7 TWRP Recovery. Then installed CyangeonMod 13 ROM and
    GApps for CM 13 Galaxy S3: Gapps 6.0 (ARM/6.0/Mini). Everything is fine infact perfect but my phone has lost network. Its detecting sim network but cannot connect/register. No Service message

    • Devs-Lab Staff

      Format system & flash ROM again. If this doesn’t fix the issues, try IMEI restore.

      • Linx

        It’s clear this rom is causing network issues with the S3, why are you still recommending it?

      • Alehandro06

        I agree on the comment from Linx below:

        ”Linx Jun 20, 2016 at 5:49 am

        • Devs-Lab Staff

          Well, looks like you are new to Android ROMs & stuffs. No one forces you to install anything. Its your device, you have made the decision to use this ROM. This bugs have occurred in latest updates, which will be fixed in next update. The ROM is provided by Official Cyanogen team.

  • Amrit

    I did install all the way mentioned here. The flash was successful but only problem I faced was that there is no mobile network. It says “Emergency Calls Only-“.
    When I tried to make a call it said “Not Registered on Network”. I tried changing other sims but it did not worked.
    Please help me with this.
    Thank You!

  • muhammad attia

    after flashing sgs3 int with cm13, sim not detected, broadband is unknown ?
    help needed
    thank you

    • Devs-Lab Staff

      Do a complete wipe (Format system,data,cache,dalvik cache) before flashing this ROM.

      • praga

        I have done this. Still no luck.. the same issue persists.. “sim not detected, broadband is unknown”.. I used CWM instead of TWRP.

    • Cesare

      same problem…I’ve used CWM. Problems with the SIM card and when i try to dial a number, S3 reboot!

  • Adam

    After the initial install I was able to use WiFi to download a few apps etc. Now, whenever I try turning the WiFi on it says it’s searching but then next time I go into the network list menu WiFi is off again.

    I don’t have a SIM card for this phone, was mainly wanting to use it via WiFi for music etc but now it’s useless.

    Any advice would be great.


    • Devs-Lab Staff

      Goto Recovery & Fix permissions, Wipe cache & dalvik cache. Now reboot & check!

  • LjL

    How EXACTLY can this add “Finger Print support” when the S3 does NOT have any hardware fingerprint sensor?

  • kathir selva

    I have flashed the cm13 on my i9300..
    All things went right and the both rom and gapps were flashed successfully ..
    But the first messages in screen were : google play and google pkay services and the other gapps were stopped!!
    No one of them are working !!
    Please tell me what to do ?!!
    Notice:my i9300 is arm and I dow downloaded the pico gapps

    • Tatu

      my smartfone too

    • Flo

      let me guess: you flashed it with cwm.
      try twrp instead then it will probably work.
      as far as I know pico gapps is too less btw. try mini.
      good luck

  • Rochy

    After installing cm13 ;my phone not detected sim and wifi is not turned on:camera perfomance deecrease .any suggestion for me

  • Hey, My GS3 has no root, and it is a SGH-I747 model, locked with AT&T. It is running 4.4.2 KitKat. For some reason it doesn’t like to connect to my computer. If somebody could tell me how to root it without using a computer (and towelroot isn’t supported), that would be great. I would love to install the CM 13 on it, but I cannot do that without root, unless somebody know how to do that. Could somebody please help me? Thanks.

    • Aaron R

      You need a computer to do it. I have the SGH-I747M which is the Canadian Version Galaxy S3. It took me a while last year to get it rooted with a lot of bricking and I learnt the phone inside out. I found out how to root it after many tries and installed Cyanmodgen 12.1 on it and now I have CM13 loaded with it updating the nightlies about once a week. Have the odd little issue here and there with it but over-all I love it. If you want to root your phone and find a computer to do it with let me know and I’ll send you all the info on how to do it and the files you need.

  • Hamza Alarakia


    Much thanks for this, it is appreciated. However, when I install both the files as per the ALL the steps above, I get an error message during initial setup saying: “Unfortunately, Google Play Store has stopped”. What could be the issue?

    I used Kingo Root for rooting and installed TWRP, before I used TWRP 3.0 but all I get is this error.

    Kindly advise the soonest.

      Hey Sergio ! Instalar el gapps junto con la ROM . No arrancar la ROM antes de instalar las gapps . Muchas personas informaron de esta solución y lo he mencionado anteriormente también! Feliz de verte aquí!
