re: phone only shows nokia icon on red screen
Which recovery tool? Windows Phone Recovery Tool or Lumia Software Recovery Tool?
There have been issues with WPRT for some users.
Try powering off the phone, switch to another USB port on your PC, but don't connect yet.
Start (or restart) the LSRT. Don't connect the phone. Press Power button until it vibrates then immediately release Power and hold the Volume Down until you get the Exclamation Mark Screen
Now plug that phone into a different USB port than before. In LSRT use the "my phone will not boot or respond" option...
