Solving problem: Nokia Lumia 800 doesn’t boot

Happy new year….and fortunately happy new solution! (I don’t really know if I’m lucky because of all those solutions or particularly unlucky because of all those problems!!)

Anyway: this evening my almost new (only one month old) Lumia 800 didn’t boot.

I found this simple solution from Nokia’s website (completely different of my personal experience with LG customer care).

  1. Connect your phone to your PC and start Zune
  2. Press and hold (for 10 seconds) both Volume down and Power buttons until your phone will vibrate
  3. Release them and after a little it should restart

Hope this will help a lot of you, as always!

Happy new year everyone


How to resolve “Can’t connect to your phone. Disconnect it, restart it, then try connecting again.” issue.

Some days ago, I started to get this error message when trying to connect my Windows Phone to Zune.

“Can’t connect to your phone. Disconnect it, restart it, then try connecting again.”

I tried that once or twice – didn’t help: after investingating it, i found the following solution. Unfortunately, it seems the cause of the problem is that I changed my user’s password after installing and using Zune, so it will appear every time I’ll change it in the future.

1. If it is running, close the Zune software.
2. Open Certificate Manager (click Start, type certmgr.msc and press Enter).
3. Expand Personal and then expand Certificates.
4. Click the heading for the Issued By column to sort the column, and then look for one or more certificates that is issued to “zune-tuner://windowsphone/…”.
5. Right-click the certificate and then click Delete. Click Yes.
6. Browse to C:\Users\<UserName>\AppData\Roaming\Microsoft\Crypto\RSA and delete a directory named something like S-1-5-21-2994215280-4243257845-4001642984-2731
7. Start the Zune software and connect your phone to create a new certificate.

That’s all…
