Ten steps to successfull Himalaya/WM2k5 upgrade.
====================================================================

Note:
The Radio_.nbf is an optional component,
not included in this archive
====================================================================
The nbf file is configured for operator ID O2 and language ID WWE.
If you need to change these, carry out all the steps below.
Otherwise proceed from step 5.
====================================================================

1. Extract the decrypted versions of the nbf files
   by entering the following commands at the command prompt:

      xda2nbftool -x NK.nbf NK.nba 0x20040304
      xda2nbftool -x Radio_.nbf Radio_.nba 0x20040306


2. Modify the operator ID in the nbfs to the value you require
   by entering the following commands at the command prompt
   substituting <operator> with the required value:

      xda2nbftool -sd PH10 -so <operator> -sl WWE NK.nba
      xda2nbftool -sd PH10 -so <operator> -sl WWE Radio_.nba


3. Update the crc values for each of the decrypted files
   by entering the following commands at the command prompt:

      xda2nbftool -c -u NK.nba
      xda2nbftool -c -u Radio_.nba


4. Encrypt the files back into the nbf files by entering
   the following commands at the command prompt:

      xda2nbftool -x NK.nba NK.nbf 0x20040304
      xda2nbftool -x Radio_.nba Radio_.nbf 0x20040306


5. Start your device in bootloader mode by pressing and holding down:

   DPad + PowerButton + ResetButton

   After a second release ResetButton, then release the rest of them.
   Your screen will show word "Serial" at the top.
   You are in bootloader mode now.

6. Place your device in the cradle, ensuring that the cradle
   is plugged directly into a USB port on your PC and not to a hub
   and that the power supply is connected to the cradle.
   It is also a good idea to disable any screensavers on your desktop PC.

   Once your device is cradled, the text on the screen will change to "USB".


7. Run HimaUpgradeUt.exe

8. Sit back and wait for the Congratulations screen to be displayed
   on your PC. Your device will still be displaying 'Upgrading radio stack, please wait',
   but as long as the PC says it is done, then its all OK.

9. Detach your device from the cradle.

10. Now you have to hardreset your device.
    Press ResetButton and hold down CameraButton + RecordButton.
    Hold them pressed until the "Boot Options" menu appears on the screen.

    Select the options as follows:
    (for selecting use RecordButton, change values with CameraButton)

    Enable KITL          -> NO
    Clean Registry Hive  -> YES
    Format Storage       -> YES

    When done, press DPad and wait until OS starts.
