Good afternoon!

I have the following problem with my E-55:

I was often using the phone as a modem, connecting it with a cable and using Nokia Suite. Some 2 months ago the computer (and Nokia Suite) suddenly stopped recognising that a phone was connected (it remained undetected, although the battery was beginning to charge). But it was still connecting via Bluetooth.

About a month later a problem emerged with the phone's memory. Although all apps were installed on the memory card, and text messages occupied some 300kB, NetQin Mobile Guard was only finding 4.5kB files to delete from cache and I was constantly receiving an alert about lack of memory. I couldn't send text messages (although I could receive them), add new contacts, edit calendar entries or change mailbox settings (the e-mail boxes were empty). I could still use the phone as a modem connecting it via Bluetooth.


The day before yesterday, for the first time I couldn't turn on Bluetooth, but when I closed all apps (using NetQin Mobile Guard to do that), it worked.
But yesterday it didn't. I did a hard reset. The phone is working, now has over 50MB free memory (compared with the mere few kB earlier). But it still doesn't connect with the computer via cable, and I still can't turn BT on (alert: Cannot carry out Bluetooth operation).

1. What can be the reason?

2. Can it be repaired? (I expect deep reset does the same as hard reset, so won't change much?)

3. If not, is it possible to carry over contact and setting backup from Nokia Suite (in .nbu format; I expect it would have to be converted) into the phone and running it without connection with Nokia Suite?

Loads of thanks in advance for your help!

Cheers!
