Well...for me after updating to v47 and rebooting phone wont start anymore. First I thought I just was careless and battery finshed but when looking indicator light when charging it's just yellow, not blinking with yellow color.
When I try to start phone Nokia logo appears and indicator light is white so at this point everything seems to be ok - but stucks there...

Can not flash either.Computer (Windows7 & Windows XP) does not recognize USB device anymore. So when I try to flash flasher stops in quite beginning erroring "Suitable USB device not found, waiting"..
