In the Recovery Mode Shell command:
rpm -e --noscripts aliendalvik-control
If you get error:
error: "aliendalvik-control" specifies multiple packages:
then use the
rpm -command with exact versioned name from the list. I had 2 different versions installed, and removing both of them wasn’t enough to fix the problem on Xperia 10.
Also as side note, the command line is really kickass way to fix things as long as you have an idea what needs fixing. I will take the command line over forced reflashing on every problem at any day.
