2. Press 2 for Settings, and then 2 for Network Configuration.
3. If the padlock in the upper right corner of the screen is locked, press * * # to unlock.
4. Scroll to option 15. If it is set to No, press the “Select” soft key.
5. Using the up and down arrows, choose “Enable” and then press the “Select” soft key.
6. Scroll to option 13 and press the “Select” soft key.
7. Use the back arrow soft key (<<)
8. Use the keypad to type the “TFTP” address to equal the value of your desired cluster.
   • Make sure to type the periods “.” that separate the numeric TFTP values.
9. Press “Validate” and then”Save“.

Your phone will now reboot with the TFTP address you have entered.
