iphone wont connect to itunes or computer after failed update and restore
I was updating my iphone 6 last night when my laptop battery died. The iphone was in the process of extracting software and installing the update. When I reconnected the iphone "restore and update'' came up on itunes, I pressed this and error 53 came up half way through the process. I searched error 53 and the results told me to make sure I had the up to date itunes and that I was using the correct apple usb cable. I updated itunes last night and got the apple usb this morning. I then tried to connect to itunes but my iphone is not being recognised by the laptop or itunes. It also will not respond and is completely blank until I plug it into a socket usb charger when the connect to itunes screen appears. When I disconnect from the wall socket charger and try to connect to my laptop itunes the phone goes completely blank and isn't recognised by the laptop/ itunes.
Can somebody please help me I have been without a phone sine yesterday evening.
