I have a 7970 that won't boot. Screen is blank, but the bottons work when I ry to factory it, so I know it's not totally bricked. I've tried to factory the phone with both "3491672850*#" and "123456789*0#" methods, but no matter what I try, it doesn't seem to want to suck up all the files from the TFTP server. I get a bunch of different results:
Sometimes it will suck down term70.default.loads, then hang.
Sometimes it will suck down term70.default.loads, then suck the same file down again, then hang.
Sometimes it will suck down term70.default.loads, then jar70sccp.8-3-2-27.sbn, then hang.
Sometimes it will suck down term70.default.loads, then jar70sccp.8-3-2-27.sbn, then jar70sccp.8-3-2-27.sbn again, then hang.
Sometimes it will suck down term70.default.loads, then jar70sccp.8-3-2-27.sbn, then cnu70.8-3-2-27.sbn, then hang.
I have the phone connected to a Linksys switch. A 3825 connected to the Linksys and my laptop connected to another port on the linksys. The 3825 is the DHCP and TFTP server. The files were taken off of CCO directly, so I know they're not corrupt or anything.
I've been able to ping flood the 3825 from my laptop with no packet-loss and the phone auto-negotiated to 100/full on the linksys, so by all indications the network is fine.
Something I'm missing?
term70.default.loads references these files, in order:
ip dhcp pool voice
network 10.0.0.0 255.255.255.0
option 150 ip 10.0.0.2

When you do a factory reset(I hope you are using a power brick ) the phone tries to look for the default file which was originally there .. if its not there on tftp server or your router it will not boot.
You try and sniff the traffic from the back of the phone and see what file its looking for.
Once you know to try to download fresh copy of the phone load/file and also
issue the command "create cnf" on telephony service mode
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.!!!
