I have a pretty new E52 (3 month old), which suddenly decided to present a "black screen". When I try to start it, it just give a buzz.

I've tried to take out the memorycard but it didn't help.

I think I need to update the phone with firmware, but I can't get access to the phone even with Nokia software updater.

Do any of you know how to update/reset the E52 without being able to swich it on?

You could try the deep reset, but you will lose all your data unless you already have a backup.

Before you try the deep reset, try removing the battery for at least 5 minutes and then replace and see if that makes any difference.

Then try the "3 finger deep reset". With the phone powered off, depress and hold these three keys simultaneously "*" "3" "green phone" and then power on phone using the on/off button whilst keeping the three keys depressed until you hear start-up tone.
This should ONLY be done if the device doesn't power up normally anymore and it wipes everything in the Phone memory that is not part of the ROM.
