the last days, sometimes the phone didn't work, sometimes i couldn't take incoming talks ... yesterday, it blocked totally, i removed the battery, restarted, the screen is jumping continue over 2 menu's, again and again; i did a soft reset (*#7780#), the same problem, also buttons don't work; i can't use the fone no more - what do i have to do ? thanks

You might like to try three key depressed power on that works for E72 a similar S60 3rd FP2 device as here:

Keep these three buttons depressed whilst powering on until Nokia "Shaking hands logo" appears. but be warned ALL DATA would be erased from device.

If the issue persists and you're under warranty, take your phone to the dealer.
