cant change 7912 from SIP to SCCP

I have a 7912 that was configured for SIP for a demonstration. I am trying to convert it back to Skinny, but its not cooperating. Ive created a new gkdefault.cfg file with the firmware version I want.

(upgradecode:3,0x601,0x0400,0x0100,10.0.1.1,69,0x050124A,CP7912060000SCCP050124A.sbin)

When I reset the phone it finds the gkdefault.cfg file on the tftp server, opens it, recognizes the firware version and finds it on the tftp server. The phone says it is downloading software, then reboots but comes back up with the SIP firmware and its old config. I'm at a loss right now, any ideas?

Hello,

5.x is very old, can you try again with 8.0(3) ?

I tried CP7912080003SCCP070409A.sbin first, it did the same thing. I only tried the old version because I'm using CME 3.3 right now and it was the recommended version on the matrix.

Re: cant change 7912 from SIP to SCCP

Hi Paul,

possibly the phone has previously loaded a config file with "image ID" (that is the parameter before image name) higher of what you currently have in gkdefault.cfg

Try increasing to to something like 0x070607B or any hex value bigger of what possibly was used at the time of SIP upgrade.

Also, before doing the above, try the reset sequence: power off, press and hold #, power on, wait for led to flash in pattern, release #, press in sequence 123456789*0#. This might reset the internally stored "image ID" mentioned above.

Hope this helps, please rate post if it does!
