7. Press the battery button (near the earpiece connector) and

wait 30 seconds. Press

button again.

Your XDA should now boot to the new ROM.

Notes:

1. Software tested to work on Windows 2000. Reported to work

in XP as well. Windows 98

is problematic.

2. Good place to get OS ROMs and Radio Stack ROM

3. When upgrading to WM2003 using the AT&T ROM 4.01.16, you

will not be able to re-flash

the ROM again using XDAtools. You will need to use the SD card

method.

To Do:

Changing bootloaders.
