  16. How long will this take? My S6208 entered ODIN MODE and it will not move anywhere from there.

  17. i just downloaded Jelly Bean 4.2 Rom .zip file and im not able to download ‘google apps’. is there any link web site pls inform it.

  18. hi jayesh,
    i just downloaded Jelly Bean 4.2 Rom .zip file and im not able to download ‘google apps’. is there any link web site pls inform it. and you did good job. congrats . bye

  19. Two problems
    1 provisions appears to enter download mode instead moisture and volume over written press down.
    2 I tried to update the instructions, and I got an error 7, I deleted the 3 lines script and still the problem exists.

    Would be very good if you set it up.
    Thank you for all the work…

  20. It seems that no one has installed this ROM on the 6802, so we will still have to wait :)
    i am also curios how Jelly Bean works on 6802, if acceptable then I can go on with installation.

  21. I checked the three lines in the script specified above in Rom brought up, which is what appears there:

    assert(getprop(“ro.product.device”) == “cooper” || getprop(“”) == “cooper” ||
    getprop(“ro.product.device”) == “GT-S5830″ || getprop(“”) == “GT-S5830″);
    mount(“ext4″, “EMMC”, “/dev/block/stl12″, “/system”);

    Is not this model belongs to a different Rom?
    Maybe I’m just wrong, but good to check it out.
    Thank you for all your work.

    • i try above all the process first i get error7 status then apply above three lines then i get error6 status what can i do plz tell me

    • remove assert block at the file starting and another assert block at the end and try u will get installation success…

      • Bro i’m still having same problem… Removing lines didn’t worked. N that google apps package has some errors. .apk problem s

    • ME2. Is it for S5830, not for S6802??

      assert(getprop(“ro.product.device”) == “cooper” || getprop(“”) == “cooper” ||
      getprop(“ro.product.device”) == “GT-S5830″ || getprop(“”) == “GT-S5830″);
      mount(“ext4″, “EMMC”, “/dev/block/stl12″, “/system”);

      What did it mean?
      And someone said it works
      Are those guy use S6802??

  22. I did use the above guide by deleting the ASSERT lines from the script, re-packing the ROM and then re-installing again by CWM.
    Result was: installation aborted (this time without specifying any type of error).
    So, still can not install JellyBean.

  23. hey jayesh ,
    its great that ace duos is upgrade able to 4.2.1 , but i tried to install the rom but fails please add some screen shot so that i can upgrade

  24. Thanks Jayesh. I finally succeeded to start CWM by using your advice.
    But now I get an error “Status7″ while Jelly Bean installation.
    Any solution?

    • Thanks Jayesh. CWM you have me it works.
      But Jelly Bean do not install, an Status7 error occurs.
      Maybe we still have to wait for a working Jelly bean for 6802.

  25. I have failed trying to install CWMR first, by using the above link for CWMR for Samsung Galaxy Ace Plus.
    Maybe CWMR shall be different for 6802, but i cant find it anywhere.
    Can you please detail a little bit about CWMR files and installation method for 6802?
    Thank you so much.

  26. That’s awesome! 4.1 for Ace Duos! surely follow the post steps to do that!
    Can you please add some images of custom 4.2 in Ace Duos!?
