Hi Sunish,

Here is the reset info;

To perform a factory reset of a 7911G phone, follow these steps:

Procedure

--------------------------------------------------------------------------------

Step 1 Unplug the power cable from the phone and then plug it back in.

The phone begins its power up cycle.

Step 2 While the phone is powering up, and before the Applications Menu button flashes on and off, press and hold #.

Continue to hold # until the message LED on the handset flashes on and off in sequence in red.

Step 3 Release # and press 123456789*0#.

You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place.

After you press these keys, the message LED on the handset flashes faster in red and the phone goes through the factory reset process.

Do not power down the phone until it completes the factory reset process and the main screen appears.

There is also an alternate method in this Tac document which was kindly provided by Paolo (Thanks Paolo!)

May I add one thing to the great info provided by Rob.

Make sure that:

1- DHCP server for phone is giving option 150 pointing to the TFTP server (usually, CCM or CCMe).

2 - you have termXX.default.loads and all the individual firmware files available on the TFTP server.
