8811 fails to boot

[mtweed001]

I have an 8811 that fails to move beyond the splashscreen. The large center button is lit.

I have reset the phone:

remove power, press #, wait until speaker and headset lights are lit, release #, key in 123456789*0#, verify that the headset light goes off after the 1 is pressed, and the mute light comes on after #.

splash screen comes on and after 5 seconds, the speaker and mute light go out.

CUCM shows no status or IP address for the phone.

I see no indication in packet dumps from the port it is connected to, of communication with the mac address of the phone.

a cable test to the phone shows good cable.

What should I do next?

If you have valid Smartnet I would suggest to raise RMA.

CUCM shows no status or IP address for the phone:- You can see the status and IP when it register with CUCM.

Connect phone any working port if still having same issue like stuck on upgrading, Cisco logo & blank screen  that’s means phone having bootstrap loader issue(firmware of phone which is stored on flash memory of ip phone corrupted), so raise RMA in this case.
