8821 Firmware Rollback

Good Morning Everyone,

 

I currently have a 5 8821 phones with sip8821.11-0-5SR3-2

The phones don't even recognise the wireless and I can't connect them to the network. I have spoken about this in other threads and the solution I was given was to configure a RADIUS auth server. 

 

I am currently waiting for the new WLC's to be able to achieve that. 

 

However, to use these phones, I need to do the * + Power on combination to load the Inactive load sip8821.11-0-4-14.

I need to do this everytime the phone powers off. 

 

I have attempted to select manually the Phone Load Name of the 5 phones to sip8821.11-0-4-14 and then tried to power the phone as normal, but it keeps loading the sip8821.11-0-5SR3-2.

 

I would like to know if there is a way to configure the phone to remove sip8821.11-0-5SR3-2 and tell it to load the previous firmware. 

 

Thank you in advance!

I have these phones running on 11.0(5)SR3 and I do not see this issue at all. 

  1. Is the correct SSID configured? 
  2. Is the Profile enabled?
