Hi there


I just upgraded my phone to IOS 6.1 and now the phone stopped pairing with my car or any other Bluetooth device (including other iPhone or iPad).


The diagnostics and usage log files contains 2 entries reporting a BTServer exception EXC_BAD_ACCESS error.


Any idea how to resolve? Can I roll back to iOS 6.0.2?



iPhone 5, iOS 6.1

    No, you cannot roll back to 6.0.2.


    Have you tried restarting or resetting your iPhone?


    Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after the iPhone shuts down, then press the On/Off button until the Apple logo appears.


    Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds). Ignore the "Slide to power off"

    I posted the below fix on another related thread.. but this is what I found:


    After an OTA over WIFI upgrade to 6.1, Bluetooth stopped pairing with any device, and lost its existing paired settings. Furthermore, I had the following issues:


    1. Could no longer join a secured WIFI network (it threw an invalid password error)

    2. BIG ISSUE! Could no longer back up in ITunes ("Could not back up because an error occured")


    Luckily I had a iCloud backup from 4 days previous to the upgrade. The only way to resolve this was to do a complete RESTORE of the phone (in iTunes), at which point it puts a clean and full install of iOS 6.1 (instead of a broken upgrade). After restore I recovered the iCloud back up.


    My advice if you are having this same issue is do a full restore as soon as you can especially if you are unable to do a backup. Otherwise the longer you wait the more data you will lose.


    The problem is not iOS 6.1, it is the actual upgrade procedure which screws up the phone.
