I have had a problem loading the last two OS releases. I go through all the steps to load the new OS (as described above) and after it has loaded the new OS and rebooted the BB, in the final steps of reloading the data (I think "loading phone settings" is displayed on the update manager progress window) the progress bar halts. I look at the BB and it says, "App Error 523, reset". No option but to select "reset". Then the apploader (on the desktop) aborts the final steps of loading. The BB reboots. I finish the loading of data via a restore of the backup made during the update process in the desktop manager. Everything seems to work fine (no errors during use or reboots), but it should finish the update properly, right? It does show the new OS version in the About pages, etc. And all the 3rd party apps work fine. Any ideas?
