After reading some posts concerning upgrading,
- I made a backup per USB
- noted my MAC address (just to be on the safe side, label on back)
- removed all cards
- charged and did not pull the plug when finished
and then connected to IDS.
For me the upgrade stopped after step 6 as well.
WLAN connection could not be established.
As I had that experience from earlier upgrades, i just removed my
WLAN settings (WEP), created a new profile with identical settings
(using the "old" keyboard, input reader method is next for download)
and finished the upgrade without further hickups.
And - overall - faster than expected.
YMMV,
