Rooting and Installing CyanogenMod with Odin


Welcome to the first in our new series on hacking your phone. We’re starting off by looking at how to customise the operating system on your phone. With Android, it’s possible to install custom ROMs and change almost any aspect of the phone’s software.

For this simple step-by-step guide, we’re going to be using a Samsung Galaxy SII (i9100 international edition) and showing you how to root it with Odin and then how to install CyanogenMod which is probably the most popular custom ROM for Android.

It has all the advantages of an unbloated stock Android Jelly Bean ROM with the bonus of some amazing extra features, massive potential for personalisation and an amazing launcher, lock screen and bundles widgets. Plus, it’s the easiest way to update the Galaxy S2 to Android 4.3 way before the networks are rolling out official upgrades.

Before we start though, a disclaimer: by rooting your phone or installing custom ROMs, you may be voiding your warranty. We take no responsibility if your phone is damaged or bricked by following these instructions.

    I just installed the latest CM-nightly. It works just fine at the start but after I reboot my phone it stops at the samsung galaxy SII logo. What am I going to do to fix it?

    • Mobile Network Comparison 18 June 2016 at 15:31 Permalink

      Try another older nightly?

      • Dzum 18 June 2016 at 15:42 Permalink

        A little earlier before I got this issue, I tried cm-13.0-20160617-NIGHTLY version and update it right after with cm-13.0-20160618-NIGHTLY. After I installed and reboot my phone almost the same thing happened but that time the Samsung logo disappeared but the screen just turned black and did not boot. Do I need to install earlier version of Nightly maybe?

        • Mobile Network Comparison 18 June 2016 at 18:47 Permalink

          Yes, that’s exactly what we just suggested.

          • Dzum 19 June 2016 at 07:02 Permalink

            It’s now working with the same latest rom. Though the gapps I’ve downloaded isn’t working. Thanks a lot. ^^

    Thanks alot. The guide was really very helpful and couldnt find any other that had each detail explained so well.

    Samsung Epic 4G Sprint (Galaxy S). Friend added clockworkmod recovery and installed rooted stock OS 2.3.6, which recently stopped being able to install apps (from Play Store, uptodown, or SD card).

    I attempted a factory reset via settings and it then would not boot past Galaxy S logo. The suggested solution was to flash the ROM.

    I downloaded CM 10.1.3 stable and the pertinent gapps and followed instructions to install via recovery partition (Vol Down/Camera/Power, wipe data, cache, and Dalvik cache) and it was all working nicely. I even got Freedompop messaging app installed and could use data and texting.

    CM notification suggested that I update CM so I clicked on the 2015 snapshot update, it took 20 min to download then asked whether to install. Yes.

    Rebooted and is now stuck on the Galaxy S/Cyanogenmod logo and I can no longer access the recovery partition. Also the battery indicator remains fully grey (despite charging a good battery in external charger or in phone) and there is no charging indicator and when I unplug the charger the indicator remains.

    I think this is all just a software problem but I cannot find any way to reflash the ROM without access to recovery mode. Download mode (1 plus power) does not work either. Any ideas?

    I am new to this. All methods seem to require recovery or download mode or USB debugging, and I cannot access any of those.

    problem with nightly installation. Hi there, I’m stucked in the middle of the installation process of the CM nightly. I installed the SU zip and it worked fine. During the installtion of the CM nightly the installtion is aborted (Status 7) .
    What can I do? The normal system is not bootable but I can enter the CMW revocery.
    The following error occurs:

    “Warning: No file_contextsdetected filesystem ext 4 for /dev/block/mmcblk0p9 Can’t install this package on top of incompatible data. Please try another package or run a factory reset E:Error in /emmc/ (status7) Installation aborted.”

    Is there a chance to recover?

  7. Carlos Prazeres 10 July 2015 at 15:42 Permalink

    I tried installing CM 12.1, everything installs fine no problems etc, but the moment it boots a 1-2 minutes later it hangs! any ideas?

    • Android User 1066 11 November 2015 at 22:11 Permalink

      I had a similar issue. Mine was a cyanogenmod update, though; not a fresh install. Clearing the cache and data files on Trebuchet solved the problem for the most part.

  8. Blog Bule 21 June 2015 at 20:59 Permalink

    Best thanks for the well understandebel tutorial. I try to do more or less the same as Summerguy above, installing CM11 M12. I installed cwm recovery GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9 – was this wrong??
    While installing cm-11-20141115-SNAPSHOT-M12-i9100 I get status 7 error as NS. It occured fairly rapidly after the start of flashing.
    What recovery should I install? Update Lenovo S850, Dump Firmware International Version ROW_S216

    Dear Team,
    I would like to thank the team for the detailed and illustrated tutorial on rooting the phone, installing custom ROM and upgrading the Android OS (10.1.3 stable). I followed all the steps at my Samsung Galaxy S2 (Intl) edition and have succeeded in doing so. Till now, the phone is working fine and with no visible glitches. I am trying out with changing different settings to make sure that everything is indeed fine.
    I would like to make here below points with regard to installation:
    1. AOSP Keyboard not working – The stock Android keyboard application is not working. In the absence of failed keyboard app, I was not able to login to Play Store and install other keyboard app. I had to manually install another keyboard application using the APK file. The other keyboard is working fine. As mentioned in comment of another user, I will try to flash the mobile with another latest version to make sure that the issue is not with the version of OS.
    2. Google Play Store Issue – I could sign in to Google Play Store but later it says no connection. Thus, installing applications through Play Store may be difficult. I will try to manually install the app using APK files. Any possible resolution?
    3. Backup of Data – While taking the backup of data using CWM Recovery tool, I forgot to put the backup of stock ROM on my laptop or external card. Once I installed the new OS version and performed the factory reset/ wipe cache, I believe that the backup must be deleted as well. I believe that I could download the stock ROM from internet, but is there any way that I can retrieve the existing ROM Backup from my device? Any particular folder/ file that I should look out for the backup of data? I would like to keep this backup for versioning purposes and to make sure that I have a working fall-back option available with me.
    Thanks again for the detailed info and the steps outlined here.

    • Mobile Network Comparison 20 March 2015 at 13:54 Permalink

      Thanks for your detailed comments. The Play Store should be working correctly. Are you certain you have the correct version of gapps?

      • Sumit Chhabra 5 April 2015 at 06:41 Permalink

        Unfortunately the Play store didn’t work as expected. I had the correct version relative to the OS and mobile device. I tried to perform the installation multiple times but somehow the google error didn’t go. Other issues with the installation were that I was not able to use any google app, most important of all, Google Maps and Navigation.
        Later, I found out that it may be because of an issue with the partition size at my SG-SII. The link mentions that certain S2 devices have a small partition size and thus separate google apps installer needs to be used. I took the latest small binary google apps and Android KK package from CGM, and followed the procedure. Surprisingly, all things have went till this time. I am using the device for past couple of days and things are fine. All google applications and other installations are working fine. Google maps and navigation and play store are also working fine.
        If I come across any other issues or things of importance, I will post them in few days.

    I tried to root my phone which is basically the same as the one on the video: Galaxy S2 i9100 XXMS2. I installed the ClockworkMod Recovery successfully (I guess) via Odin. I put the CWM-SuperSu-v0.97 also put the cm.10.1.3 zip file into my ext.SD as well as the gapps-jb-20130813 zip file. Everything was fine until the last steps, and now the phone’s screen is black and I don’t know what to do… When I reboot the system, the cyanogen mode didn’t start. Please tell me I can find my phone back ^^

    Thanks in advance for your help( and sorry for my english)

    Hi Team MNC, I was trying to install the cyanogenmod on my s2 as per the steps mentioned here however I had not copied the downloaded files into my internal sd card & started the process later realized I had missed it, then tried to copy the files onto an external sd card & tried to install the zip files and unable to do it. Please HELP !!!!

    It mentions E: Can’t mount /sdcard /

  22. Dan 30 April 2014 at 11:41 Permalink

    Files transferred onto SD card, now I’m getting an Error 7 when I try and install Cyanogen Mod.

  23. Dan 27 April 2014 at 22:46 Permalink

    When in recovery, it won’t mount onto a readable disk on my pc. The prompt for new device comes up, but no openable folders.

  24. Dan 27 April 2014 at 22:09 Permalink

    I will try! I don’t have a MicroSD card reader atm, so will try that tomorrow.

  25. Dan 27 April 2014 at 10:10 Permalink

    I ****’d up. I forgot to put the files on the IntSD, and carried on with the process. I’ve installed the Kernel with Odin, but have no files to install from when I load up into the Boot mode. What do I do? The phone won’t load up normally, it shows the yellow triangle Samsung screen and switches off.

  26. joe 25 April 2014 at 00:13 Permalink

    dude, for people who dont know, make it clear in the video, that we need to copy the zip files to the internal storage and not the folders, as you show in the video. Its confusing.

  27. Francis 20 April 2014 at 15:07 Permalink


    I need your help since this is my first time rooting a phone, and I got stuck in the recovery mode half way through while following your steps in the video.

    My Samsung galaxy s2 is the correct model, i1900 (the international model) and I had downloaded all the files provided in your links, however it appears that I’m stuck with the error of ‘status 7’ while trying to install CyanogenMod 11.
    And by reading the previous posts I think this is because the ClockWorkMod that I’m using is outdated.

    I’m at lost here so I really need your help please, do I install the latest Clock Work Mod (I tried installing the, its on my computer) or can I use a CyanogenMod 10 version? I don’t know what to do, do I use Odin to transfer the files onto my phone? And How do I get out of recovery mode on my phone?

  28. igsram233 15 February 2014 at 19:55 Permalink

    Thank you. I was able to bring back the Stock Android to my phone with your step by step guide. Thank you once again.

  29. vawaver 3 February 2014 at 18:26 Permalink

    Thank you for the tutorial. Everything was working fine until latest nightly 4.3.1 – .

    New one is cm-11 based on core 4.4.2 but there is no Google apps package on on their website yet. Can you recommend other (same quality) package or better way is to wait?
    Thank you for reply.

    • Mobile Network Comparison 4 February 2014 at 11:41 Permalink

      There is no equivalent. You’ll have to wait/find it elsewhere. Just stuck with CM 10.2.x for now…

      • vawaver 6 February 2014 at 18:55 Permalink

        I just find out that new file with filename appeared.
        I suppose that it is new gapps supported 4.4.x Kite Kat core.
        Can you confirm that?
        If I am right it means that I can install new Cyanogenmod 11 on my Samsung Galaxy S2 with this “gapps” package.
        Thank you for your reply.

  31. fidgol 6 January 2014 at 14:58 Permalink


    My Phone looses signal completely few seconds after boot, installing CM with new kernel couldn’t fix that problem, coming from stock android.
    Any solutions?

    • Mobile Network Comparison 6 January 2014 at 15:11 Permalink

      Does it work with any ROM?

      • fidgol 6 January 2014 at 15:13 Permalink

        I’ve tried stock rom and the cm 10.1 stable. Do you think flashing a new radio helps? Another Problem is the keyboard FC-ing every time.

        • Mobile Network Comparison 6 January 2014 at 15:14 Permalink

          Which keyboard are you using? Try installing another. Flashing a different radio and trying CM 10.2 might also be worth a try.

          • fidgol 6 January 2014 at 16:02 Permalink

            neither cm 10.2 nor new radio fix the problem. yould it be a hardware problem?

    can i use odin mobile to do this? and being that my devise is already rooted do i skip a step?
    thanks alot

        I Can Charge the fone but for some reason the fone will not connect to the computer.
        I recently bought the s4 and that has no trouble connecting to my laptop but my s2 wont 🙁
        I cant access my fone via my laptop in ne form 🙁
        I Have tried with USB debbuging and without… new drivers… uninstalled kies reinstalled it… even tried *#7284# changed the settings and changed them back!
        also tried to connect to Odin via download mode… but no help;(
        that is the best link i found to help… but been all over XDA aswell

        • Mobile Network Comparison 24 December 2013 at 17:46 Permalink

          Make sure you remove all existing drivers and install the ones from our link using the instructions we provide. Are you talking about the Odin step or in general?

  34. CwChou 6 December 2013 at 16:11 Permalink


    Thanks for the tutorial. It is very useful. Before I start to do the above steps, my phone is the G variant. Hence, couple of questions pops up:

    1. Can we proceed with your steps although my phone is G variant? Is the steps still remain the same but just replacing the Cynogenmode & ClockWorkMod kernel with the G variant? Does the SuperSU link provided can be used for G variant?

    2. After performing the above, will I be able to have my existing apps & settings back(i.e., WIFI password saved)? Does the option of backup appearing in the CLockWorkMod able to backup all these or should I just back it up on my laptop of all my apps before I commence above steps?


    • Mobile Network Comparison 6 December 2013 at 16:17 Permalink

      1. Yes. Just make sure you install CM and kernel for your version of the phone. Super SU is fine for both.
      2. No – it’s a completely fresh install. Like reinstalling Windows. You start from scratch with a fresh system. There are apps in the Play Store you can use to back up your apps and settings though.

      Good luck 🙂

      • CwChou 7 December 2013 at 16:56 Permalink

  36. Roee 29 November 2013 at 18:31 Permalink

    Well, I do have SuperSU on the phone and it seems like it works properly. I don’t quite understand what “flashing” means. How do I flash the SuperSU?
    Also, When I try to activate the STweaks app it says “Sorry, no kernel support”.

  37. Roee 29 November 2013 at 18:03 Permalink

    My Samsung galaxy s2 was rooted when I installed CM 10.2. After installation the Root Checker app showed that the device is indeed rooted but some of the apps that need the root permission such as AdAway and STweaks don’t work and they act as though the device is not rooted.
    Please help. I need those two apps, how can I make them work?
    Thank you,

    Hello, I would like to ask whether it would be possible to download a ROM for Lenovo A789 mobile phone. I have this phone, where one guaranteed Czech language but unfortunately there is only Chinese and English without the support of Google Play, simply the application and trade them in Chinese. It would thus your ROM, as well as in Czech language respectively. it subsequently upload it there? Thank you in advance for your help in solving my problem. Czech Republic, Google translation 😀

    • Mobile Network Comparison 12 November 2013 at 19:30 Permalink

      Yes it is possible to download a ROM for the Lenovo A789. Have you checked xda-developers? Unfortunately, the ROM we used and the best one we know only supports English, Chinese, Russian, Indonesian and Vietnamese. The other multilanguage ROM we are aware of doesn’t support Český either. Sorry but we couldn’t find anything either. If you have no luck, we might be willing to buy the phone off you?

      • Lukáš Podruh 12 November 2013 at 20:35 Permalink

        Thank you for your willingness, for now I’ll phone you and I will continue to look for a ROM that would support a Czech language, perhaps from CyanogenMod or MIUI, etc..

        • Mobile Network Comparison 12 November 2013 at 20:44 Permalink

          Don’t bother looking for a CyanogenMod port – that’s almost certainly never going to happen. Good luck!

  39. Konstantin 7 November 2013 at 16:33 Permalink

    hey, first of all thanks for the very detailed video. But unfortunately im stuck with the odin process. When im in download mode and connect the phone (samsung Galaxy SII i9100) to the computer, it wont show up in odin, but i can hear the “connected” sound. Strangely, my samsung will show up in odin when not in download mode.
    I need help please! 🙂

    • Mobile Network Comparison 7 November 2013 at 17:50 Permalink

      Your drivers aren’t installed correctly. You’ll probably find it’s connecting for a few seconds then disconnecting as it’s not recognised correctly. Make sure you remove all existing versions of the drivers and then make sure they are installed correctly so that Odin can see you phone. Let us know how you get on…

  40. ASRY 4 November 2013 at 13:13 Permalink

    Hi there! thanks for complete and easy tutorial video.
    however I found that one of link (Triangle Away App) given is not valid any more. It’s ok to continue the proses without that Triangle Away App or can you provide me new link to download that app.

I needed help to settle recovery back my phone. More worse its my computer even can’t track my phone, it will put my phone on charging mood. Please I needed you help.

        • Mobile Network Comparison 6 November 2013 at 11:49 Permalink

          You don’t install the ROM with Odin – you only install the kernel. Did you make sure to follow the instructions about which boxes to tick?

          It should be possible to fix your phone by reflashing the kernel again.

            Thanks!!.. I do possible to fix it.. 🙂 .. the question here could I still use kernel “GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9 (2).tar”, whereby my Galaxy S2 version was GT-I9100G?.. I try one again with “GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9 (2).tar” to change my kernel and its stuck once again at “Galaxy Samsung GT-I9100G”, and this time I fail to reflashing the kernel again.

              If you don’t have a i9100 it’s very important not to use a i9100 kernel! The i9100G is a different model of phone as it runs on a completely different system-on-a-chip. Make sure you use the correct kernel and ROM for your particular model of phone 🙂

    Hi there!
    Thank you for the excellent tutorial and video. I was able to install CyanogenMod 10.1.3 with you directions in no time.

    I have some questions:
    1. Is the CWM kernel enough to root the phone and if yes why do you need the SuperSU also to do that?
    2. Why are you linking this version 0.95 of superSU instead of the latest (1.65)?

    Although I have flashed many ROMs in Windows Mobile 6/6.5/7 era I am a newbie at Android, so please have mercy …

    Thanks again!

      1. Yes – the kernel will root your phone alone. Sorry about the confusion about SuperSU – this is a root access management app, not an actual rooting app. It won’t root your device, it just lets you control when to give apps root access on an already-rooted phone. Does that make more sense?
      2. This guide is now a few weeks old – it’s always best to use the latest version currently available.

      Good luck and let us know how you get on! 🙂

        Thank you for your reply.

        I did the test to install only the stable 10.1.3 ROM and google apps and not the SuperSU. As a result the S2 was not rooted.

        By the way #superuser menu is in the CM ROM!

        Then I tried to use the latest superSU 1.65 but phone remained unrooted. Only when I passed again through CWM recovery the superSU you suggested I had root access again.

        In some XDA forum I read that this superSU is the rooted kernel!

        I am getting really confused here! I need to understand what my options are with CM ROMS.

        I want root access mostly for CPU profile handling and install things like FM radio that CM does not have! Otherwise I want to stay on safe side.

        Could you please analyze the process a bit more!

        Thanks again!

          Have you managed to get your phone rooted now? If so, we’d suggest you leave it that way. As long as you don’t allow SuperSU to give random apps root access, it’s hard to see how there could be any security implications.

          • George 4 November 2013 at 19:39 Permalink

            The way you suggest it is rooted!

            I am trying to learn also by the process, so if you have time please answer to my questions above.

            Thank you.

              Which questions haven’t we answered? If your phone is rooted and you have SuperSU working to manage root access, you’re sorted 🙂

                I see…
                Anyways Thanks a million again for the great tutorial! It really was a great kick off to start searching more..

      I got the CWM for my S6810b to try to use it with Odin just like you did firstly on the video. However, I noticed in your video it shows the extension “tar” while mine the extension is recovery.tar.md5.
      I’d like to know whether Odin can work with both extensions to accomplish the CWM?

    does rooting galaxy s2 brick the device? is it safe to proceed with rooting as i am goin to do it for the first time…any advice bricking?

    • Mobile Network Comparison 25 October 2013 at 12:47 Permalink

      No, it shouldn’t brick your device at all but, as mentioned in our warning, it is possible for things to go wrong. As long as you follow the instructions correctly, everything should be fine. Do make sure your device is not susceptible to the EMMC brickbug though…
