So that's 203 Days... You either have to wait that long or Hard Reset your phone. You will lose data but can restore your last backup during setup.
From powered off > hold the Volume Down button > tap Power > when the exclamation screen (!) appears immediately release Volume Down
Now tap in order: Volume Up / Volume Down / Power / Volume Down
The screen will switch to the two gears and the stored OS in memory will be flashed to the phone. Plug into AC so you know you have power...
