  1. Thanks, it worked.

  3. On fallowing this steps i got stuck … and got fail
    did thrice.. but no way…
    read some forum but wrongly used a pit file(For international version used chinese)..
    Now my mobile is hard bricked…
    No display.. but when battery is inserted the device is getting heated up.

    Do you have any idea to bring it back alive.. Help needed

    • Remove battery for some seconds(5-10). Put the battery on and try to boot the Phone in downloadmode. Maybe you can’t do il at the first attempt, Just try more times or put it on charge and retry after an hour. In you can boot in downloadmode you are safe: download the official samsung firmware ICS 4.0.4(for example from sammobile) and flash it with odin. At the first boot enter the recovery mode and do a wipe data-factory reset and finally the Phone should boot correctly.

      • I’m generous, i give you the link for the fw ;)
