I had 6280 2 years ago (some of you may know this allready

). I had many problems but its been over a year since it doesnt work. It has keypad hardware, radio hardware and powering hardware damaged. I took it to my friend who knows a lot about hardware and he told me that small part of hardware is covered in some kind of specific glue so it will be hard to remove broken stuff from phones main board and replace them.
I decided to take it to nokia care. Will they be able to fix all this?
