There is a folder with a long serial number. It has only a dulog folder containing a 0kB "DeviceLog.cab" file. At one point that folder may have had stuff in it, but I have deleted this folder many times to retry the process. It is currently empty. Since then the updater does not even see my phone to try to get cabs anymore. It does appear in the Windows Devices though.

The time it seemed like it was going to work, it got to the point where it said to check your device for updates and I did not see any. After waiting a long while I disconnected the phone to retry.

I have Windows 10. There is not Windows Recovery tool on that machine.

I will continue to try the updater until it gets the folder properly populated. Any pointers? Does it need WDRT to work?

On a side note, I had an identical phone (1020) that I first upgraded to Windows 10 mobile the same way (iutool) and it was able to auto-update to RS after that without trouble. The phone I'm currently trying to update does not get any auto updates. Do you know the mechanism for getting auto updates and why one would get them and the other would not?

The updater not "seeing" your phone anymore is a typical iutool bug. You should go to control panel (not settings), devices and printer and remove all Phone entries you can see there. After that reconnect your phone and the updater / iutool should again recognize it.

There are many reasons why one phone might have gotten an update and another one didn't. One of them is a corrupted database or other files. If that is the case it's best to go back to Windows Phone 8.1 and upgrade again to Windows 10 Mobile. But the updater should warn you about that.
