[Asterisk-Users] How do I factory reset a Grandstream BT-102

[WipeOut]

Hi,

Just pulled out the BT-102 because I need to use it again, entered in 
the TFTP server to get the latest firmware so its now in 1.0.6.7 and i 
now was to factory default the phone and set it up from scratch..

I tried the instructions (copied below this message) from the latest 
available version of the user guide on the Grandstream site but it 
didn't appear to work..

Anyone got any idea how to factory reset these phones?

Thanks



8 Restore Factory Default Setting
Warning: Restore the Factory Default Setting will delete all 
configuration information of the device.

Step one: Find the Mac Address of the device. The Mac address of the 
device is located on the bottom of the device. It is a 12 digit number.

Step two: Encode the Mac address.
The encode rule is:
 2  is the first letter on the button  2  so its encoding is  2 .
 A  is the second letter on button  2  so its encoding is  22 .
 B  is the third letter on button  2  and its encoding is  222 .
 C  is the fourth letter on button  2  and its encoding is  2222 .
 3  is the first letter on the button  2  so its encoding is  3 .
 D  is the second letter on button  2  so its encoding is  33 .
 E  is the third letter on button  2  and its encoding is  333 .
 F  is the fourth letter on button  2  and its encoding is  3333 .

For example, the Mac address is 000b8200e395,
User should encode it as  0002228200333395 .

Step three: Access the phone screen menu, then select the  -- reset --" 
with the up or down arrows keys.

Step four: Dial in the encode of the Mac address. Once the correct 
encode Mac address dial in, the device will reboot automatically and 
restore the factory default setting.
