Before you run the ROM Upgrade Utility (RUU), make sure you check and do the following first:



1. USB sync cable is connected to your device and PC to establish a connection with Activesync.
2. The standby and hibernation modes are disabled on the computer.
3. All running applications on the computer have been closed.
4. Ensure that you device has a battery level of at least 50% (Start>Settings>System Tab>Power>Battery tab). If the battery “diesâà¢Ã¢â‚¬Å¡Ã‚¬Ã‚ÂÂ� during the upgrade process, there is a chance that it will not recover and will need to be sent to AT&T/HTC 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 prior to upgrading.
7. Do Not interrupt the upgrade process or press any buttons until the process has been completed (the device will reset itself when the update is done).
