  8. Mayank Shah says

    Hello All,
    Both my wife and I have Samsung Galaxy Grand Duos. Device info shows same Android version (4.2.2). However my phone has many more options than hers. Example 1: When I press a contact for a few seconds I get 10 options such as “share contact via message” / “print contact info” / “share name card” etc. Her phone does not have all these options, only 3 options like “edit” / “delete” / “add to group”. Example 2: When I open a picture in Gallery and press the bottom left button I get options like “slideshow”, print, and many more, but only 2 options on her phone. There are many more other differences, which I fail to understand why If both are same phone models and both having 4.2.2. Please spare some time to enlighten. Many Thanks in Advance. Regards Mayank.

  9. Michael Clemenia says

    Sir already did that couple of times and still “no command” error and android recovery only. Was it because my phone’s been upgraded to 4.2.2? Because i use the same process on my wife’s grand running on 4.1.2 and successfully rooted it. How does that happen?

      You can unroot galaxy grand by removing the SU binary file & Superuser app from your phone.
      SU binary app location > System/bin (and/or) System/xbin

    • Abhijit_Guha@admin says

      You can upgrade its Android OS with to latest available firmware, also you can install Cyanogenmod ROM. Which is one of the best CUSTOM OS. Hell lot of thing you can do after rooting Galaxy Grand DUOS.

  11. Nitin says

    “failed to verify whole file signature is the error im repeatedly getting while starting my device in recovery mode i.e. vol up+home+power buttons.
    moreover I can see only following options at start:
    reboot system now
    apply update from adb
    apply update from external storage
    wipe data/factory reset
    wipe cache partition
    apply update from cache

    pls suggest.

      • virtussavant says

        samething happen to me. i did flash the CMW…received “PASS” message in odin.
        but when i hit the volume up+power+home button, im entering the stock recovery page.
        how do i know if the CMW flashing are succesfull?

      • 419 says

        Hi abhijit,
        there is a solution to add to the tuto. it is battery removal as soon as “pass” is received in Odin. this prevent phone to backup to stock recovery once restarting.
        then all your tuto works fine

          • 419 says

            This particular one, no, the one linked to it being a first step to be able to follow this one, yes.

            You must have forgotten but yes Odin is used on the other tutorial needed to fulfil this one.

            I am just commenting on this one based on the initial comment from one guy having an issue to follow your current tutorial.
            I had the same issue and was stuck exactly like the guy.
            So for such guys having followed your step by step process, i just enlight the little trick that allowed me to move forward.
