  1. odin didn't detect my phone, in cwm recovery mood, it only detect my phone when it is open not closed

    1. 1) try using other USB port, don't use any external USB hub to connect your device
      2) Disconnect your device from PC, uninstall the USB driver and re-install again then connect your device

  2. no i got my phone on downloading mood. and it says do not turn off target
    but odin doesnt detect my phone or any thing. i dont see anything at the ID-COM box
    please help me with this issue

  3. Hi, Muhhamad,
    I have just coming back from Shanghai and just bought this one for my wife.
    It seems Kies recognised it and update it to this rom version. However i have some questions:
    It seems the mobile phine is China Unicom branded. Which meens there are some pre-define china unicom apps in it.
    The other major issue that i have is that there is not google play parket, google maps .. or whatsoever.
    Is this because of the branded rom. is there any way to fix that and what is most apropriate one to battle this issue.
    My main purpose would be to be able to use the google services, but it seems i can't just flash it with some european firmware.
    Also on some forums i have read the some branded versions would be "bootloader locked", which would mean you would brick the phone if you try to apply unbranded firmware.. however it is not mentioned here.
    So i am a bit confused what to do.

    Best Regards, Chavdar
