Do any one have performance issue with Samsung Galaxy S duos s7562.
I am very much disappointed with my device as it will get stuck on screen. Huge Lag time. Will take time to go to application after clicking on icon. Cannot play HD videos. While receiving calls the screen will go black, You can hear the ring but cannot see anything on screen. Any help will be appreciated. :(

Check if CWM is not set to require signature.

Go into CWM click Install Zip from SDCARD>Toggle Signature Verification. Should see "Signature Check: Disabled"

CWM = ClockWorkMod recovery.

You must flash it with odin and then install the superuser zip in recovery mode.

See detailed step by step procedure on page 5 of this thread. And do not skip any step.

Well, don't know which script do you mean but there is some playing with vold.fstab file. This method can't be used as is because S7562 uses some obscure combination of vold.fstab and deprecated vold.conf

I tried two times to switch the volumes by modifications of these files and both time I had to spend tens of minutes to make the phone work correctly again :)

Thanks for the reply. The method I mean is this . I've tried to run this script in my mobile, but doesn't work fine

Have you finished the odin part from tutorial ?
if yes, then switch off your mobile and reboot into recovery by pressing all these 4 buttons together : Vol UP + Vol. Down + Home + Power.
Once you see the Samsung logo, release all keys.
Once your phone reboots into recovery, make sure it shows as "CWM Recovery or Clockworkmod recovery"
If it shows as Recovery 3e, it means you are using the stock recovery.

Now select the files from here and then install.

You first need to flash ClockWorkMod (CWM) using ODIN3 as described on page 5 of this thread. Please follow the instructions step-by-step and do not skip any steps. Otherwise find someone local who can assist you.

Not fully, still waiting for answer if the script mentioned in this thread will work or not.

As quite a good workaround you can use app called DirectoryBind. Only condition is that you are able to fit the application into the internal memory. Then the app can move it.
Works only on rooted phone!

    Here is the full guide. If you like, please press the thanks button, ;)

    CAUTION : It will VOID your Samsung Warranty and set/increase your custom flash counter.
    You will also see a yellow triangle below Samsung logo during each boot.

    Please take a Full NANDROID Backup using CWM once CWM is flashed. This is useful in case you want to return to Samsung Official stock ROM or in case something goes wrong.

    You can flash back to stock recovery if you don't need CWM any further OR if you want to remove the yellow triangle.
    Samsung stock recovery is attached below with this post.

    Requirements :
    1. Samsung Galaxy S duos S7562 Phone
    2. Latest USB Drivers for Samsung Mobiles (http://forum.xda-developers.com/showthread.php?t=961956)
    3. Odin Flashing Tool (http://forum.xda-developers.com/showpost.php?p=32500955&postcount=35)
    4. CWM 5 Recovery (http://forum.xda-developers.com/showpost.php?p=32500955&postcount=35)
    5. Superuser or SuperSU ZIP (attached with this post) (any one of them)

    Procedure :
    1. Install latest USB Drivers for your Samsung Mobile in your PC.
    2. Switch off your mobile.
    3. Press and Hold "Vol. Down + Home + Power" buttons until the phone vibrates.
    Once phone vibrates, leave all buttons.
    4. It will Show you a Warning.
    Press Vol. UP button to Continue.
    5. Now you will see [Odin3] screen on phone which is Download Mode.
    6. Connect your Phone to your PC and wait till it install the drivers.
    7. Download and Extract Odin.zip
    Open Odin. It will detect your phone on some COM Port.
    You will see screen like this :
    1krfn.jpg


    8. Now click on PDA and select the recovery.tar file.
    Now, it will look like this :
    8FbMS.jpg


    9. Now make sure the following :
    Auto-Reboot is checked.
    F. Reset Time is checked.
    All others are unchecked.
    Click on start.
    Odin will start flashing.
    wait for atleast 2-3 minutes.
    Odin will automatically reboot your phone and you will see Pass written on Odin.
    Keep the phone connected to your PC.

    10. Let the phone boot properly and then close the odin.
    11. Now, for Rooting, you have two options.
    Superuser or SuperSU. Both works good, you can choose any of them.
    so, Download CWM-Superuser-3.1.3.zip OR CWM-SuperSU-v0.96.zip and copy to your MicroSD card.
    If you don't have MicroSD card, you can copy it to phone's internal SD card memory.

    12. Boot into CWM Recovery Mode by :
    Vol. UP + Vol. Down + Home + Power
    Keep all of these pressed until you see samsung logo and then release.
    Use Vol. Up and Down to navigate and to select, use Home button. To go back, press Power button.
    IMPORTANT : GO to "Back and Restore" and create a FULL NADROID BACKUP by using "backup" option. It will be very useful in case something goes wrong.

    - "install zip from sdcard"
    - choose zip from sdcard (if files are in external microsd)
    OR choose zip from internal sdcard (if file are in phone's internal sd card memory)
    navigate to CWM-Superuser-3.1.3.zip OR CWM-SuperSU-v0.96.zip and select it.

    That's it.
    Go back using power button to CWM Home screen and reboot the phone.

    Hi again :)

    Someone know what combination of keys we have to do for enter in recovery mode?:)

    Hi,
    Press The following combination for booting into recovery. (Works fine for me)
    Keep all of them pressed until you see the samsung logo and then release them all.

    Vol. UP + Vol. Down + Home + Power On

    CWM and Odin is attached. Flash this CWM package using odin (make sure you reboot your phone into download mode for using odin)

    I'm NOT responsible for any brick or other mis-happening. I tested it all on my galaxy S duos and it works fine.

    Edit : CWM 6 replaced with CWM 5and reuploaded. CWM 5 works much smoother for me.

    Link2SD Working!

    Hey folks,

    Finally got Link2SD working properly on my rooted s7562.

    There are many guides out there so I'll just tell you what I did specifically for our phone to get it working.

    I used MiniTool Partition Wizard (on my Windows 7 laptop) to create the second partition on my 32GB micro sdcard. The important part is that it needs to be FAT32, and not Ext3 as most guides will recommend you use. Ext3 was what I tried originally without success. I was getting "read only" errors when trying to link to second partition.

    I haven't tried the Ext2 or Ext4. FAT32 worked so I'm happy.

    The native "Move to SD card" option in Link2SD does not work, (presumably because it's not natively supported on our phone) but the "Create link" option works fine. Which is what we want.

    I have moved (linked) a few apps over and tested they are working and all is good.

    Hope this helps some of you.

    Regards
    Keliuss

    P.S. Please feel free to thank me below. :)
