Is there a reason you were trying to flash your iPhone? Normally, a -1 error is baseband related and this could be indicative of a damaged baseband IC or it's solder connections. Has the phone been dropped much over its lifespan? Has it come into contact with water?

I was updating iOS and it didn't complete.

It apparently took a flight down some stairs.

Then it's highly likely there is a bad solder joint on the baseband chip. A micro solder should be able to fix it by reflow / reball.

Error -1 on 3uTools may be caused by USB cable connection, network and baseband.

Try to change the usb cable, confirm the network connection. If error still exists, you would need to change the baseband.
