There is a Fix folks.
Please do not go about opening your iPhone and removing battery etc. The good folks at NOC59 (who manage our corporate IT network) got this working in about an hour. Here are the steps. Some have been explained before. But here are the steps.
My iPhone was a 6 Plus. 1970 issue as of 24 hours ago.
Steps:
1.Plug iPhone cable into USB port of Computer but not into the Phone, Disable AntiVirus ( including Firewall of MAC if using OSX). Ensure iTunes is updated.
2. DFU Mode. Press Home and power buttons until the Apple logo disappear, then release the power button keeping the home button depressed. While doing so, insert the cable into the iPhone now. iTunes should launch and indicate the phone is in Recovery Mode. Do nothing else. Don't bother pressing buttons on iTunes. Remove the cable end from the Computer.
3. Leave phone on like that, not connected to anything but in Recovery mode; it will have an Apple logo, and heat up but more importantly will run through battery charge.
4. Important, place this Phone, with its back on an ice pack ( I used ice from the fridge in a plastic freezer bag. Ensure the bag does not leak or you will have a water damaged phone next!
5. Once the battery has drained to the red level, unplug it and plug it into a wall charger, while keeping it cool.
6. My phone just sprang to life with the "HOLA" screen. It is completely wiped but nobody has to break the seal and disconnect battery. I am proof that the phone is not bricked, or needs to become a doorstop etc.
Total time taken by the NOC59 team: 1 hour and 15 minutes. Thanks.
