Greetings. I'm having problems when charging device and I'm 99% sure USB-port is broken. When charging, notification led flashes the regular fading yellow, but between yellow flashing color is red. I checked dmesg and got I ran into problems when I attached it to PC as well.
Is it broken port as I suspect or could it be something else? If it is, could the dmesg be a good indicator for people who are not sure if their port is broken?
I already bought a new phone before the replacement N8, which I'm going to sell immediately. My new phone is naturally a second hand N900 =), which still has over 10 months of warranty.

I'd say try reflashing first because it could be a software issue (I'm not sure though, I'm just guessing).
