7970G blank screen

[info]

Hi!

I recently bought a Cisco IP Phone 7970G from a company and want to change the firmware to SIP.
But after a reset i get a blanc screen, nothing works.

Now is the issue that sftp don't want to connect.. He can't find the phone, the phone is directly connected to the router.
My knowledge for sftp is very low so i don't understand how i can fix it..

These are my settings;

What can i do?

If you have CUCM installed, please build the phone as SCCP in CUCM and do factory reset on  phone with following steps.

• Power off 7970.
• Power on 7970 (with a power brick) while holding the # key.
• The lines lamp should blink amber in sequence. ...
• Press 123456789*0#.
• The lamps should blink green in sequence.
• The phone obtains IP information through DHCP.
• The TERM70.default load loads on the phone.

Your phone will get SCCP firmware from CUCM and get registered as SCCP Phone.
After that sftp will work.

below link will help you to get your phone converted to SIP.

Tried it a thousand times haha. 

The reset works, but instead of blinking green, the upper button is orange and its off. After a while it blinks again and the speaker button is green (for another reset) 

So it doesnt blink green :(

[Moshfiqur Rahman]

Sorry about that, I never realized that you already have done that.

Instead of CUCM, try using CME, put CME in option 150 of your DHCP scope

debug tftp event  on CME router and  run factory reset on the phone.
Thats the way you can see if your phone is trying to communicate to tftp or not. If you see activity in debug output  you will understand what is missing.

Sorry, what exactly is CME and how to use it?

I currently use TFTPD (which apparantly isn't working) my knowledge about this isn't going that far. :(

[HARIS_HUSSAIN]

No Need of TFTPD or SFTP for firmware upgrade.

You just need CUCM/CUCME for the same.

Try to register the phone to CUCM and it will download the firmware from it automatically.

Make sure phone is able to reach the TFTP Server. Also make sure the DHCP Pool of phone is having correct Option 150 pointing to your TFTP server CUCM or CUCME.

Are you working with CUCM Or CUCME.

1) No Need of any separate Tftp server, CUCM/CUCME can act as TFTP server.

2) With CUCM it should work if you add phone as SIP and reset the phone. You can check the Device Protocol on Device Page as below

3) Make sure phone is able to reach the TFTP Server. Also make sure the DHCP Pool of phone is having correct Option 150 pointing to your TFTP server CUCM or CUCME.

Please take time to Rate and mark correct if applicable

Nope, not working with any of that. I was just used to SIP with other Cisco phones, not with this one.
