All-
In a previous post, I asked, and was answered about 7.5.4 not 'sticking' for certain phones. https://supportforums.cisco.com/thread/2216529
What I'm observing to be more specific is that the 7.5.4 is applied successfully (or so it appears on the device and in running the
spa50x-30x-7-5-4 executable).
However, immediately after it renders the successful upgrade message, the phone shows that it is downloading and applying the 7.5.2b firmware again.
Is there a setting on the 504 or 508 devices that restricts firmware from being applied, or?...
Thanks in advance.
