    if we install cwm recovery and later flash a new rom, does the previous backup data will be deleted?

    • No, as long as your sdcard data still intact, the backup is there.

  • wni

    litening 6.1 doesn’t hv cwm. so can we just simply install cwmmanager.apk or do we need to root again using cf-root? need help here~

    • It has CWM but no CWM Manager. Just boot into CWM will do.

      • wni

        owh~ thanks

  • aladin

    which one is better: this CWM back up or back up via Titanium Back up?

    • Both are not the same. CWM is full system backup. TB is good for ROM upgrade.

    hi , how to recover or witch image to recover without recovering previously wiped firmware in order to instal new ROM?
    do i have to recover in advanced recovery in CWM?
    thank you

  • igor

    when i recover after installing new ROM,it brings me back to my previous firmware version.And installation includes deleting of all data.
    The Q is : How to recover or which file to select to recover ?(boot,cache,data,system and there is nandroid.md5)

    thank you

  • wni

    hey jayce~ does cwm backup the external sd card too if the ext-sdcard is in the phone?

    • Nope, it stores at internal sdcard only.

  • wni

    during backup process

  • kelvin

    jayce ,i use cwm manager backup when i go to the clockworkmod/backup file and open the file tat nothing???

    • Hmm… The backup files should be there. Anything different when compare to the video above?

  • Jat

    Hi, I tried to do CWM back up but get an error “can’t access to /system/csc/ORA/system” Successfully applied multi-CSC appears below. Any idea?

    • Hmm… No idea. Maybe it is the things that you installed wrongly that causing this error.

  • Jat

    I have rooted correctly I believe as I have ROM Manager and also CWM, I get the normal ! when I boot up the phone. Most applications will ask for SuperUser Access and is then granted, this will only happen on rooted phones I think? I have BVKH2 Kernel but could not find an insecure one to match so I used DXKH2 instead. Shall I root the phone again?

    • Yes, SuperUser will give access to those apps that need root access.
      No need to root again. Your phone is rooted already.

  • Jat

    Thank you for your quick responses. I have one question, should I use CF Root? I don’t believe I have used this for anything??

    • You already rooted your phone and have CWM, right? If yes, why do you want to use CF-Root again?

  • Jat

    I havent used CF Root at all I dont believe. I did not have Superuser as an app I had to download this manually and also CWM. If I used CF Root, I thought this may solve my backup issue as it would use Clockwork Mod Recovery..

    • “can’t access to /system/csc/ORA/system” might be caused by incompatible kernel because yours is Orange carrier branded firmware. You might need to flash non carrier branded firmware in order to use CF-Root.

  • Jat

    Any idea which one I could use?

    • I am using XXKI4 now. You can try it if you want. Note – I am not sure it will work on carrier branded SGS2 or not because I did have one.

  • What’s the difference between the two backup methods? Sorry newb question..

    • Basically, they are the same. Just one with better GUI.

  • Gagan


    Please help i’m new to this i tried both options CWM Manager & ClockworkMod Recovery you have showed
    i’m getting boot screen but its not taking Backup please find the error screen shot link

    I’m using XXKI4 2.3.5 S2 i9100

    hi jayce. am trying to do system backup (am using custom rom). but when i perform, it said no sd_card or ext_sdcard found. does my backup complete?
    if not how do i fix it

    • No if nothing in sdcard\clockworkmod\backup folder. Are you using CWM to backup?

  • Koen

    If one uses ROM manager to try out different ROM’s.
    I suppose you can then use Clockworkmod to restore back to the stock ROM.
    Let’s say after rooting you restored the stock kernel…

    Then … what happens if firmware upgrade is done with KIES?

    Does this overwrite Clockworkmod? How does it conflict with ROM manager? Will root access stay after a Samsung upgrade?

    • I don’t use ROM Manager. No idea.

      Yes, upgrade new firmware with Samsung Kies will overwrite CWM. Root access will be removed too.

      • Koen

        So if I understand correctly, there’s firmware, kernel and ROMs. And if I will root the phone and use ROM manager to install CM7, it will put a custom kernel and a ROM. Maybe I am wrong about this?

        So let’s say Samsung updates the firmware to fix a few bugs to make their ICS ROM working better and I’m using CWM+CM7. Can I follow your instructions here : ? To update the firmware without attacking my recovery manager and the ROMs? Or will it “fxxk it up” as well? Sorry if it’s stupid questions, it will become more clear when I have my phone I hope.

        • Use CWM to install CM7.

          Install official firmware will remove CWM and root.

  • Lucas

    Dear Jayce,
    for this CWM process, need to take how long for downloading?

    • Depend on your data to backup.

  • Lucas

    Dear Jayce-san,

    thank you.

    may i know, how about memo, can back up as well? or can sycn to gmail account?

    thks 1st.

    • I think so. Didn’t use memo much.

    hi jayce,

    when i do a back up using clockworkmod-recovery, this message appeared.

    “cant mount back up path”

    can you pls. help. just a newbie in android.

    just rooted my phone using cf-root
    kernel dxkl3.

    • Which CF-Root did you install?

  • Nash

    Hi Jayce,

    I’ve got the same issu with Jeff. Is it because that i did not enable “USB debugging” during the rooting process…if so how do i rectify the issue. Please help as i want to install custom firmware and i wouldn’t do it until i did the backup..thanks.

    • Are you using CF-Root Kernel?

  • jeff

    hi jayce.
    sorry for late reply.
    i solved my problem already.
    i back up stock rom and im into custom rom
    im now using checkrom revo hd and siyah kernel v.2.6.11

    tnx a lot..

  • aksjata
