7970 Bricked ?

[mitchdawson]

Hi All,

Has anyone had any issues with 7970G phones coming up blank after an upgrade to UCM 6.0.1 ? We have had three phones all go down when registering against the new version. The line,headset and mute lights come on but there is no output on the diplay to indicate whats happening - its completely blank, and stays that way.

Cheers

Mitch

Either phone doesn't receive right dhcp options, cannot contact TFTP server, or TFTP server doesn't have term70.default.loads and individual FW files.

I never seen a phone really bricked so far.

Hi,

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.!!!

Use older firmware, like 7.x or 6.x

Really never???  I had a pallet of phones get speared by a forklift once and that yielded some bricked phones

Try an older firmware version, 6.x or 7.x

Also try alternate reset sequence.
