Dear Cisco Support Community,

I have problem with one Cisco 7970G VOIP Phone. I was reset it (press #, power on and then the orange line leds blink to down I enter the 123456789*0#). The Phone was in the Updating mode. I switch it of from the power cord and 30 Minute later I connect it again and the display can not power on - all other work led blink as before but the display not switch on. I do not know where is the problem and not I can not upload the new firmware.

P.S. I also add and the other code for the HARD Reset 3491672850*# but without successs.

I wait of Your answers... Thank You in Advance!

Best Regards,

How are you powering up the phone?  Power brick?  PoE?  Injector?

Can you leave the phone powered up?  This process can take up to 45 minutes.
