Hi everyone

I need your help. I was calling and my N900 just froze and after that constantly rebooted. I took out the battery as I did not have time to have find a solution at that time and it stopped rebooting. I found the instructions on how to reflash but the problem is that I cant enter the USB mode (hold down u while connecting USB) I thought it might because of the battery but I have left it for 12 hours in charge with it constantly rebooting while connected but still no luck.

Second I have searched everywhere on how to get support from Nokia but I cant find that either

Can anyone help me with this one ?
