failed 14 to 15 upgrade

Hi, just wanted to let you know that the upgrade failed from 14 to 15 on mine. Don't know why, it still booted but I kept getting 404 errors in the interface which also prevented me from flashing another firmware.
Maybe it has something to do with that I did the manual install (way way back) with a pre 10 firmware?
There probally was a better way cause I did still have ssh access but I just popped the HDD out and except sd?8 redid the manual install using 10 and then directly flashed to 15. Now it works perfectly and using the occasion to reorganize and clean it up a bit.
