Product: Apple iPad, iTouch, iPhone, iPod
Version: Any version
Error message: Cannot sync [device] an unknown error occurred (1150)
Firstly, I tried to find a solution in Google, but nobody gave the right answer, and everyone is asking the question.
I found only 1 hit in Discussions.Apple.com dated 2012-09-30, which is strange, and nobody answer it. So I trace back what I done in my iPad that could produce this error.
The root cause is related to
restriction that I turned on to disallow deletion and installation of
software in iPad. This basically make sense as iTune will install and delete
applications (app) during sync. As it can't perform the operation into
iPad/iPhone/iPod/iTouch, it throws an error, which is not user friendly
The solution is to allow apps installation & deletion as below:
4. Turn on for "Installing Apps"
5. Turn on for "Deleting Apps"
disconnect and reconnect iPad/iPhone/iTouch/iPod (if not connect), or
(if connected) press "Sync" button to sync again. It will not throw the
error any more
Kindly donate CAD$1 to value my research (which everyone points me to wrong solution) and 10 hours of figuring out this solution
