Well, i ran the same code. This time i went to aat diagnostics and i went to a different section.
I ran the vibrator settings there (red screen with a slide bar) failed it, then ran it again and to my surprise it worked again. Vibrating functions are back!
And i think the radio problem in the zv6 update rom can be fixed like this as well.
I tested the radio hardware already. I will reinstall next fm radio app and check the reaults..
