7971 boot loop

Unanswered Question
Apr 15th, 2009

I have a 7971 connected to a UC520 and it gets stuck in a boot loop. I did a factory reset with both 123456789*0# and 3491672850*# and it does a successful reload from the tftp service but after that it still gets stuck in a boot loop where it flashes the white Cisco screen for 10 secs and then 1 second of default background image then it reboots again. Any suggestions?

I have this problem too.

LIkely it is failing to load some FW file, check the output of "debug tftp events" to see which one.

I checked the tftp events and all files were found. This is on a default install of UC520 using the 7.0.2 package. I have not changed anything with the config other than the initial setup.

I got in this morning and the phone was up and running. What ever it was doing for several hours finally finished.
