I tested the update to 4.6 about 5 times, i was always greeted with the blue ambience. I thought it was patchmanager related, so i uninstalled all patches, checked if the fpd packages were updated, reinstalled lipstick packages, since i could access the phone via ssh. Tried sfis-upgrade, nothing helped. On one installation attempt it worked, but the system wasn’t properly updated, half of the new packages were missing. I just restored my old rootfs and home backup and gave up.
