Edit Letting the phone to completely drain the battery, charging it, turning it on and selecting the Reset your phone option solved my problem.

You will probably have to hard reset your phone using the Windows Devices Recovery Tool.

  • This would not work, my phone would not show up when connected to PC.

  • Have you tried a soft-reset while the phone is connected to the PC and the WDRT is running?
