-Device is not ready for unlocking. This error message displays when the user tries to unlock when the phone application (not the device) is not in a steady state. It takes 30 seconds after powering on the phone for it to reach a steady state.

Troubleshooting:

Stage 1:

If your handset does not accept the unlock code please follow the instructions below

You need to be in an area with good cell phone coverage.

Please follow these exact steps

1. Insert a T-mobile SIM card
2. Hard reset the iPaq by holding down the power button and pushing the soft-reset button until the device restarts.
3. Go through the setup procedure with calibration and get to the default home screen
4. Verify that there are service bars showing in the top of the screen and the green/orange phone light on the top right is blinking green
5. Wait 60 seconds after verifying everything is ok
6. Enter the unlock code, it should be accepted by the second time

If these steps do not work, please insert a different SIM card and start at step 2.

Stage 2: (HP iPaq 6300 series)

You will need to download and install the ROM update from:
http://h18007.www1.hp.com/support/files/HandheldiPAQ/us/download/22572.html

There is a bug in the loading of the firmware that does not allow some iPaq's to unlock. After you have completed the update, follow the unlock instructions above again.
