I dropped my iPhone 6 a few months back , it was dead so I plugged in the charger and luckily it turned up but after 2,3 minutes it restarts on it's own,later it was stuck on Apple logo blinking,I further tried restoring it and now it shows iPhone can't be restored due to error 4013. I have been surfing and googling these past few weeks but couldn't find any exact reason but have seen lots of ads with no possible solutions. please help me in getting out of this issue THANK YOU an iPhone user with a broken heart of error 4013

If you see error 9, 4005, 4013, or 4014 when you restore your iOS device - Apple Support
