I have a AT&T factory unlocked Galaxy Note 3. Now that I am back in BC, I have it working on Koodo. I would like to update this phone to Lollipop 5. When I go into the update section of the settings menu, and initiate an update, I get a message that "No software is available for your phone at this time the update was interrupted, try again in 23 hours and XX minutes. I notice that at the top of the update page, that the AT&T server is listed, so assume that the phone is trying to get the update from AT&T. How can I persuade my phone to go to the Koodo server to look. My son also has a Note 3, which he has updated already with no problem. I have tried going into the mobile networks area of the connections menu. Under access point names, Koodo is listed. yet if I go into the network operators section, I see "search for AT&T MicroCell" How can I get this phone to go to Koodo to get the update?? Many thanks, Dave.
