Please read the following important notes before starting the upgrade:
Before you proceed, please confirm that this software upgrade is a newer version than what is currently loaded on your device.
If it is the same version and your device is operating normally, there is no need to reload the software. To determine what version is running on your device, refer to the image on the left (the newest version is pictured) and note the ROM version and Radio version. Next, go to Start > Settings > System Tab > Device Information on your device. If your ROM and Radio versions are different than what is pictured at left or the ROM Date is older, you should upgrade.
Before you run the ROM Upgrade Utility (RUU), make sure you check and do the following first:
1. If you are having challenges connecting with ActiveSync, please try the following on your device: Start > Settings > Connection Tab > USB to PC and de-select Enable advanced network functionality.
2. The standby and hibernation modes are disabled on the computer.

3. All running applications on the computer have been closed.
4. Ensure that your device has a battery level of at least 50% (Start > Settings > System Tab > Power > Battery Tab). If the battery "dies" during the upgrade process, there is a chance that it will not recover and will need to be sent for repairs.
5. The update can take up to 25 minutes so set aside time when you will not be interrupted.
6. All data will be deleted from the device during the upgrade (music, pictures, 3rd party applications, etc); be sure to back up all of your data using ActiveSync (Windows Mobile Device Center, if you are running Windows Vista) prior to upgrading.
