How to load into Samsung Galaxy S2 ClockworkMod Recovery Mode?

  1. Turn off Samsung Galaxy S 2.
  2. Press and hold down Volume Up + Home + Power buttons at the same time.
  3. Release all buttons when you see SGS2 Logo.
  4. ClockworkMod Recovery will be loaded then.

Most of Samsung Galaxy S2 custom firmware are installed through ClockworkMod Recovery Mode. Therefore, it is a must install mod for those love to try out custom firmware. Besides, CWM also provides Nandroid full system backup and restore feature which is very useful. My only wish ~ my Samsung Galaxy S2 is 32GB version. 11.5GB sdcard internal storage is not enough for me…

    Hi, Jayce

    Good day, but not for me.

    Need ur helping hand if you would, I successfully loaded my Samsung GS2, however, when I try to MO my phone battery, it fail and restart. Once it restart it keep repeating the Samsung splash screen and never load into home.

    I try to do hard reset as forum below, but I never get to the screen menu for option as below


    IF the phone is hang up or frozen, Try to turn it off first and do a hard reset through key combinations.

    1. If your Samsung Galaxy S II is frozen, Shut the POWER OFF, take the battery out and put it back again.
    2. Hold the Volume Down button
    3. Briefly Press and release the Power button
    4. A menu will then appears that let you allows for Fastbook, Recovery, Clear Storage, and Simlock
    5. Select Clear Storage by pressing the Volume Down button
    6. Quickly Press and release the Power button
    7. Select Volume Up for YES and Volume Down for NO”

    Thanks, appreciate ur help truly.

        Hi Jayce

        Thanks and appreciate for your reply. Apologize that I don’t know how to express exactly, I’m really newbie, first time play on Android phone and got crash :(

        However, below are what I did in chronological order

        1) I did and success

        3) Did & fail
        http://forum.xda-developers.com/showthread.php?t=892297

        4) Outcome
        It restarted, and keep restarting at Samsung start-up flash screen repeatly, can not load into mobile home screen.

        This morning, I bought to Malaysia Samsung Service Center. They mention can try to flash my phone. Now, black out – can’t start the phone even pressing power button.

        Thanks, appreciate that

        ps: I bought from Bangkok, is Malaysia version different? Btw, I did try to do the hard reset but same. (Vol Up + Home + Power button, then Wipe Data/ Factory Reset)

        • http://www.jayceooi.com Jayce

          Not sure about Bangkok version but Singapore and Malaysia are using KF1 firmware. But in term of hardware, they are the same.

          Sorry, can’t help much now since your phone can’t be powered on. Else you can load into Odin download mode and install a new firmware.

    It’s all right man. I guess Samsung Service guy doing the same, put into download mode and insall new firmware.

    Btw, I screen capture baseband version is DXKF1, Build number is Gingerbread.DXKF4

    Anyway, thanks alot man. Last, any alternative solution or suggestion? send back to where I bought – Bangkok?

    • http://www.jayceooi.com Jayce

      Can you still load your SGS2 into Odin download mode? If cannot, there is nothing you can do now. Try to contact Samsung support at Thailand if Malaysia support can’t help much.

    • http://www.jayceooi.com Jayce

      Look at your SGS2 box (behind bottom left) or Settings – About phone – Model number.

  • Joseph Sun

    I flash my s2 to xxki3 but the baseband still xxkh3 -.- arghhhhh

  • Joseph Sun

    i9100 not g version

    • http://www.jayceooi.com Jayce

      Good. Then you can use everything that I showed in my blog. :)

      Your recovery issue should be solved after you restore back to stock firmware. And don’t use ROM Manager if you installed CF-Root Kernel. It is not compatible.

          Load into CWM mode buttons are in the post.

          • hamid

            hey good morning still not loading what can i do?

            • http://www.jayceooi.com Jayce

              Hmm… CWM might be corrupted in this case. Try to install official firmware with Odin. But not sure can work or not. Because you need to wipe data and cache with recovery first.

              • hamid

                so? what you suggest now you think if i get it to a pro shop can they do any thing with professional tools?

                • http://www.jayceooi.com Jayce

                  No idea about pro shop as I did not try it before.

    Hi jayce,

    I have been using litening rom 6.1 (KH3 base) for months and a found out the cwm installed is V4.0.0.2 (same as your picture) and i tried to update to v4.0.1.5 thru CWM ROM Manager application in market. Even tho it show in the ROM Manager as it the latest 4.0.1.5 but when i got to recovery mode its still 4.0.0.2

    also tried to flash to KH3 Chain Fire kernel, but still is the v4.0.0.2
    Please advise on how to update the Clockworkmod recovery.

    thank you.

    • http://www.jayceooi.com Jayce

      Sorry, no idea. I don’t upgrade CWM normally. I use CWM version that come along with CF-Root.
      By the way, why do you need to update CWM version?

      • Dedi Lim

        hi jayce,

        thx for the prompt response, well new version sure have better stuff :D just kidding,
        just afraid coz the version is old might have problem flashing or restoring back up.
