You can also use a multiple key combination to reset your phone to the factory defaults. Select one of the models below, press and hold the keys simultaneously during the updater/BootROM countdown process until the password prompt appears:
- VVX 1500 phones—4, 6, 8, and * dial pad keys
- VVX 300, 310, 400, 410 phones—1, 3, and 5 dial pad keys
- VVX 500 and 600 phones—1, 3, and 5 dial pad keys
Prior to the phone's UC Software release 4.0.0, the multiple key combination only resets the device, clearing the flash parameters and deleting all log files. Within the updater, this is still true.
