Probably a faile software update.

check that is getting an IP address, and if requesting files via TFTP.

(btw, I like this name, iphone)

Re: iphone 7970

As I mentioned, you need to connect to a DHCP and TFT server, and check that 1) it is getting an address, and (2) is requesting image files.

There is no interaction with the phone keyboard and display in doing this.

Try resetting the phone to factory defaults:

-Power off the phone.

-Hold down the number sign (#).

-While holding down the number sign (#),connect an AC adaptor to the phone.

-Continue to hold down the number sign (#) until the line buttons blink amber.

-Release the number sign (#).

Enter: 1 2 3 4 5 6 7 8 9 * 0 #

The lights should change color from amber to red and the phone should be resetting to factory defaults,

Hope this helps.

Re: iphone 7970


I actually tried something stupid. Maybe I did not realise it while i did it but later on knew that both phones are now useless. I tried factory resetting my 7970 phones without a power brick. Now i just have 2 phones which just wont boot up. I tried everything I found on teh internet. tired using uploading load files using cme4.3 and cucm 4.3. tried upgrading firmware with the latest firware but it is just stuck and after about 3 months i now feel that i've lost my phones for good. all that happens is the line buttons keep blinking and the headset button is green and the mute button is red. When i tried using call manager express, i used a debug on the router and i can see phone asking for an ip address and also for teh firmware and my tftp providing it. after all that is finished i see no outputs and the phone still wont start. the screen is blank and i cant see anything on it. tried teh factory reset and all other possible things but still stuck. COULD SOMEONE PLEEASE HELP ME OUT.!!!
