i have a UC520. i recently upgraded software pack to 8.2.0. i received the typical auth fail message so i performed a factory reset of the phone. now it shows that it is trying to upgrade but remains at 0K when downloading term75.default and moves no further. i am stuck. i have tried to load several different phone loads to try to solve the issue to no avail. any help would be appreciated.
No, GP, the phone has no firmware at all on it now. Just reboots and tries to pull it and fails. I am now catching a glimpse of the "Auth Fail" message when it fails. Should i try and load the 8.5.2 firmware on the system and see if it will complete the upgrade? I don't know if that is the issue but it seems to be the next thing that i may attempt.
