Hi. Can anyone help please. Bought a second hand Lumia 925 32GB a while back and have not been able to get it to connect to any pc by USB. The pc doesn't even make the connection noise for when you plug a USB device in. It seems there is a physical problem inside the phone, preventing it form working. I have changed the USB connector/ Flex myself and I have also sent the phone off to a repair centre on ebay who couldn't fix it. Thing is, I'm not sure whether to just accept it is broken and un-repairable or maybe someone on here might know if this issue is known and if it is worth sending it elsewhere. Perhaps someone on here might also know of a decent service outlet that might be worth trying. Obviously it can be quite costly, so I want to make sure it is worth my while even considering this. It is such a shame because the phone is in excellent condition and other than this, it is fully working. It is a serious problem not being able to connect it though and I was obviously well shafted by the person I bought it from. Anyone have any suggestions?
