      Please verify the md5sum to be sure you got the right one.

Before you install CM9: Preparation (First three are optional. If you want to start fresh, these can be skipped)

  1. Install AppBak from Market, run it and save a list of all your apps.
  2. Install SMS Backup and Restore from Market, run it and backup your SMS history.
  3. Install Call Logs Backup and Restore from Market, run it and backup your call log history.
  4. Boot into CWM5 recovery. Make a full backup. You will need this backup later if you decide to go back to your previous ROM and data.
WARNING: Many apps will Force Close crash if you restore data from a previous ROM.


  1. Use CWM5 or CWM6.
    • Warning: Only use this recovery to flash CM9. Otherwise, you risk bricking your phone!
  2. Wipe data and cache.
  3. Flash update*.zip.
  4. Flash gapps*.zip. You must flash gapps after every upgrade to CM9 since /system is formatted, wiping your previous add-ons.
  5. Reboot phone.
  6. After you setup your Google account, reinstall the three apps from Market in order to restore most of your apps, call log and SMS history.
  7. Warning: Do not restore backup data of system apps!
    • If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.
    • It seems that restoring backups can also break Calendar sync.

Upgrades from previous versions of CM9 are the same process as install, except you do not need to wipe anything. Contrary to popular belief, you do not need to even wipe cache and dalvik-cache when upgrading between CM9 versions. You only need to wipe if you are doing a major upgrade, switching to a different ROM entirely, or attempting to fix bugs caused by bad backups or corrupt app data.


  1. I use Miui , its the best with LBE guard which I can stop auto start of program , that mean excellent ram !

  2. IS this Mod completely stable already? Last time i flash CM7 very lag

    1. not stable yet. but it can be use for daily usage

  3. Is it 3g video call still cant be made in cm9?

  4. please provide another link coz i cannot download using mediafire

    1. We now give a free direct link to download cm9. Happy downloading

  5. i cant download via direct link ... ?

  6. When i try to dial *122# the # key is automatically taken out. it will just dial *122. Anyway to make it dial *122#?

    1. probably because you save the number. try to delete all the contact with the number *122 . I can dial *122# just fine. also, reboot ur phone might also help

    2. aahhh yes... Thank you very much, now its working. Didn't have this prob when i was on stock gb rom.

  7. Só uma pergunta, eu sou meio leigo em relação a ROM: Funciona Câmera, Video, Wifi, Bluetooth, GPS ,3G ,e outros ? Alias, me diga o que não funciona como o normal ... Desde já, grato...

    Parabéns pelo trabalho que vem fazendo nesse blog, estou adorando !

    1. Everything works fine in cm9 now. Camera can capture and record like usual (HD), video playback works fine, wifi, bluetooth, gps, 3g working like usual. Everything is awesome except for the radio. No radio app by default in cm9 but you can download spirit fm free from google play store and listen to radio like usual.

  8. How to see task manager..?

    Would be delightet to hear from you guys.

    1. i can't find radio app & face unlock is still having problems, gtalk is disconnecting the caller network. on my phone it is stable.

    1. Use this app:

    2. hi... im need ur help.. by using this rom right.. my battery running off more faster.. any apps can help regarding this problem.?

    3. To save battery in cm9, U need to flash this kernel.
      Go to that link and download V1 kernel. (Do not use v2 or v3)
      Flash using cwm.
      Download set cpu here:
      Open the apps, Set the governer to ondemand and set scheduler to sio.
      Remember, everytime u flash an update from cm9, u need to flash this kernel and do what i said above.
      CM9 kernel use lots of battery. By using this v1 kernel, You can save lots of battery

  12. Hey Kent I have a problem using this rom, my internal SD card isn't detected. How to fix it?

    1. Go to File Manager. Click at the mnt button located at the top left. You should see you SD Card and external SD.

  13. hi kent, need your help.. i use camera apps and i can take picture using back n front camera but.. the problem is now i cannot zoom in and zoom out.. can u help me regarding this problem.?

    1. Reduce the resolution. Zoom in or out can only works when the reslution is less than 4mp.

  14. Cant open the playstore
    whats so i do?

    1. Make sure u flash gapps after every time u flash cm9.

  15. guys, anyone can help to reply me ?
    I wanna ask about , any software for upgrade my galaxy W, i need a software that is sure stable,and does not have any problem when install in the phone ..any one can tell me which one is better ?

    1. Use stock rom is u want the most stable one. But cm9 is also stable. No problem until now.

    2. The stock ROM sucks compared to CM9, even though it's not working 100% perfectly. All in all this ROM works very, very smooth and quite all animations are mostly liquid and fluent.

  16. Hey guys. Just flashed CM9 Beta 3 today. Everything works smooth and properly but I don't get a GPS signal, even after using a GPS fix. I do have the problem with the "GPS Status & Toolbox" app aswell as with Facebook location and especially Google Maps. Additionally the locate qua WiFI (WLAN) does not work - any tips?

    1. Okay, the WiFi issue is solved. Dunno why, but the option of WiFi locations was disabled, though I had activated it before. Still no GPS satellite signal :/

    2. I reckon you to use FasterFix. Just choose your country and gps signal can be lock faster than ever. FasterFix:

  17. tq for cm9 .. i love it ... sorry for my english

  18. i want to ask .. if i install task manager isnt ok?

    1. Task Manager is not actually not recommended for android (even in GB roms). This is because everytime you kill an app, it will take lots of cpu usage to open and process the app once you open it again. So, this will reduce your battery life. But, if you dont care about battery life, you can use task manager.

  19. Can I skip like CM9 Alpha 4 to CM 9 Beta 4?

    1. Yes. If you want to flash cm9, you dont need to flash cm9 alpha 1,2,3 or beta 1,2,3 or other old version of cm9, just directly flash the latest version of cm9 (now beta 4).

  20. Hi..just wanna ask if your mobile networking in beta 4 works because mine still doesnt work..pls reply :)

  21. Hi kent, i've flashed the kernel v1 but the battery still dropped fast. I fully charged be4 i sleep, once i woke up it's less than 30. @@

    1. Hey hn lee ithink try to turn off ur wifi -.- because whenever ur wifi on and no wifi connected ur batter will run out so fast

  22. Hey kent im using Cm9 beat 3 then im thinking to upgrade it to beta 4 still i neep to wipe all the apps(format) or ill just open the zip then flash it into beta 4 ?

    but the gapps that've been built for CM10 are really not stable and have some serious bugs.

    So Im trying to download CM9 and follow what you've done.

    if i somehow flashed a kernel other than original kernel that come with cm9..does this affect the whole roms performance?
