My iPhone 6S was perfectly healthy and ok until iOSX 11, then the screen went blank and I could do nothing…I took it into Apple and they were able to get it back up, 2 days later I synchronised with my iWatch and it became a brick again. I took it back to Apple, but this time they couldn’t get it working, yet whenever I connect it to iTunes I get the option to Restore or Update. I’ve been through this loop many times now and in each case it fails after 5 to 10 minutes with 4005. I’ve tried various things but nothing will bring it back, since my problem they’re have been 3 updates of iOSX 11, now on 11.3, but I cannot install any of these as my phone is a brick.
Is they’re anything I can do? It was perfect before Apples bug OS release and the face that they’re have been 3 updates released in 3 weeks echo’s this.
