iTunes wont recognise iPhone
iPhone 5s model A1457.
I have two Windows 7 64 bit laptops, one has iTunes 11.4 running, the other has the latest iTunes 12.0.1
iOS was 7.something and I stupidly tried to update overthe air to 8.1.2
Something went wrong and it is stuck in recovery mode.
Recovery screen (iTunes logo + cable picture) lasts only for a couple seconds before it turns off.
Cable seems to work because it worked for other iPhones I have used.
If I open iTunes, connect the cable to my laptop, then connect the other end to my phone, the phone turns on and then goes to the recovery screen.
iTunes does not recognise the phone.
Since I cannot do anything else with the phone, it will turn back off in a couple seconds.
Already reinstalled itunes the proper way (uninstall programs in order - restarted laptop - reinstalled)
Checked device manager. I believe the phone should appear under "portable devices" or something but "portable devices does not appear in device manager.
Also, I believe there is supposed to be something under "Universal Serial Bus controllers", but I can't see anything related to the phone.
Tried using different USB ports, but that doesn't work. (also note: unplugging the cable from the phone all turns it on and shows the recovery screen for several seconds before turning off)
Did something that involved turning off itunes, disabling then enabling apple mobile support (or something like that), then turning iTunes back one - didn't work
