After installing PR.1.2 I now cannot charge or use the usb cable to charge. I can get it to charge if i place the cable in and hold it but one i have let go it stops charging. I think this is a hardware issue due to the port looking slightly dislodged but it is not hanging out. I am now in the process of planning to get it repaired but I need to know some details about the way of going around to claim this on the warranty. I live in the UK. 1: I have misplaced my Carphone warehouse receipt (where i signed up for the contract) and my n900 box, will this hinder me in anyway/shape or form in getting my phone successfully repaired or replaced. 2: If CPWH say it is a problem with Nokia, will I have any problems that were outlined in q1? 3: If Nokia say that the problem is not covered by warranty, what would be the best course of action to prove that this is indeed a manufacturing fault and thus, their problem? 4: Anything else I need to do before I can apply for a fix? Thank you in advance.
