Hello, I have an iPhone 6 that I went to update to the latest firmware earlier today through iTunes and it went into recovery mode and I haven't been able to get it out. I tried it on my brothers MacBook Pro and when downloading the firmware on his laptop the iPhone randomly pops up again on iTunes as if I have disconnected it and reconnected it although I haven't, I have also tried another cable but it still did the same thing. When I leave it and let it finish the download as it is about to start the install on the iPhone it says "There was a problem downloading the software for iPhone "iPhone". The disk could not be read from or written to. Does anyone have any idea of what I could try or any type of solution? Thank you.
