Cisco 7970 Phone not booting after Factory Reset
I followed the below mentioned Factory reset method
1) power off the phone (if using inline power, just remove the ethernet)
2) hold the hash (#) button down
3) supply power to the phone (if inline power, just insert the ethernet) while still
holding down the hash button
4) when the line buttons scroll down orange, you can take your finger off the hash button
5) now press the following buttons: 3491672850*#
6) the line buttons should continue to scroll, but now they should be red
7) after about 60sec, this will change to green, and the phone should the boot up
The usual reset method with the Sequence 123456789*0# just took me to the Splash scrn with the Bulls eye and the Cisco logo. So I tried the other method of factor reset what u mentioned the sequence 3491672850*# . The line buttons did a scroll of red and after that the phone didnt boot up. Instead the mute button flashed red and then speaker button turned green for few sec and then the lne 1 blinked orange and after that there was no sign of power at all. When i reconnect the power adapter it does the same thing. (mute button flashed red and then speaker button turned green for few sec and then the lne 1 blinked orange and after that there was no sign of power at all.) . Pls help me to get this fixed.

I had a similar problem with a 7970 that was completely bricked. I had tried separate tftp server (TFTP32) and firmware.
I found, using as separate tftp sever such as above worked; but only after using Option 66. Option 150 would only send the Term70 file but fail. Once I changed to option 66 all the files downloaded fine and phone unbricked.
Hope this helps

Try firmware 8-5-2, I had the same problem.

I did a hard reset and the phone couldn't even talk to the TFTP server (my laptop) to copy the firmware.
I guess the phone is totally condemned.
Anyway, thanks for your reply.

I used the production DHCP server (the same server I used before I performed super hard reset) but still no luck. Anyway, appreciate your responses and suggestions.

Thanks Geoff. Able to see the MAC address and also it's getting IP address. Realized the issue was due to the Windows Firewall.
Turned it off and the phone managed to talk to tftpd. However, back to the same stage I encountered 1 week ago.

I am using 8-5-2 (see attached). Is this the correct firmware that you are referring to?

Unfortunately, this doesn't happen to my phone. It is still showing blank screen.
"Once recovered completely - takes about 5-10 minutes (works for both from Blank screen and Bullseye Errors) I reverted the option 150 to point back to my CUCM server, power cycled my phone and it continued the update process to the latest firmware."

Tried setting the timeout to 300 sec and waited for more than 30 mins but nothing happened. Perhaps 8-5-2 doesn't work for my case?
CUCM version: 220.127.116.1100-7
IP Phone Model: 7962
Active Load: SCCP42.9-3-1SR1-1S
Device Default Load Information: SCCP42.9-1-1SR1S
Note: The new batch of IP Phone that we purchased were pre-loaded with SCCP42.9-3-1SR1-1S. I recall when I performed factory default reset previously in one of the old batch IP Phone, it was able to boot up properly. Not sure if it has anything to do with the load information.

after you let the device sit for 30 minutes pointing at your laptop, did you then try to point to cucm?
what's your latest update?
