Hi, just want to ask if any of you experienced this but my Lumia 925 won't open. It keeps showing the "nokia" welcome message and will freeze.and then when i plug it is only shows the battery is at red/no more battery.
Not knowing your specific problem details.
I would say the battery is completely flat and needs a few hours on a reliable charger before the phone can boot up.
Plug it in and try a soft reset (hold volume down+power button until phone vibrates). May have to do it a few times. Had this problem 6 weeks ago and had to restore phone with recovery tool. That would be the next option if it continues.
