Try the hard reset key sequence. Unplug changer, then keep holding volume up and plug charger
Wait till a I mark appears, then leave button.
Press one key once: vol up, vol down, power, vol down. Gears should appear.

Wait till process end

try the hard reset or using windows device recovery tool


Hard Reset really should be a last resort. Use Hard Reset when the phone is completely unresponsive and no other method will work.

• Power off the phone > hold Volume Down > press Power > keep holding Volume Down until you see the exclamation (!) screen, then immediately release the Volume Down
• Now tap Volume Up / Volume Down / Power / Volume Down
• You should see the spinning gears and your phone will reflash the last OS version held in recovery. You do loose data, but get your phone back. Sign into your Microsoft Account and restore your backup during the set up.

Factory Reset is Done through Settings > About > Reset your phone (8 & 8.1) or Settings > System > About > Reset your phone (W10M).

• You should see the spinning gears and your phone will reflash the last OS version held in recovery. You do lose data, but get your phone back. Sign into your Microsoft Account and restore your backup during the set up.

In case of Hard Reset & Factory Reset the phone goes back to the exact version you were running when you performed the reset.


WDRT For right now, Windows Device Recovery Tool is only flashing 8.1 to models that did not launch with 10 so it is the way to revert if you don't care for W10M: Windows Device Recovery Tool FAQ
