W890i NO Connection + Charging EMERGENCY HELP!!!

Hi I have a W890i which i wanted to unlock so i plugged it into usb cable and the computer would not detect it. Tried different computers and different cable, checked other phone on comps and cables and it detected phone.

Now the battery has died and it won't charge put another charged battery in and the phone switches on but it will not charge this battery either.

When i try to connect usb cable by pressing and holding C or 2+5 it goes into mass storage mode but the pc does not detect it at all. Tried installing USB Drivers made no difference.

Really need to get this phone to charge battery and conect to pc any help would be really appreciated. Just post any questions and ill answer them asap. Thanks for the help.
