restore in case of hard brick

all of this needs to be done via Windows PC. (in my case Win10), disabled anti-virus SW

• docs (tried a lot - only this one worked): https://forum.xda-developers.com/moto-x4/help/hard-bricked-how-enter-emergency-t3757472
• not quite sure if this step is essential:
  • remove all qualcom drivers from windows
  • install old drivers from http://forum.xda-developers.com/attachment.php?attachmentid=3261089&stc=1&d=1428980071
• downloaded blank flash tool here: https://drive.google.com/file/d/1wfNOTMquSJFcCjCtaxf1lrSPVABm9XTS/view
• unpack, start cmd connect bricked phone to usb and execute "blank-flash.bat" and device will come up in fastboot mode. This may have to be repeated several times after resetting the phone by long-pressing the power button.
