Error 14 when updating to iOS 5, Error 14 when updating to iOS 5

I am trying to update my GSM iPhone 4 to iOS 5. It successfully downloaded without issue. When I try to update my device, it goes through the installation process but I get the following message: "The iPhone "iPhone" could not be restored. An unknown error occurred (14)." This has occured at least 30 times over the past two hours. My phone is bricked an unusable. Does anybody know how to get around this?

Nope, restarting computer is not the correct answer or solution to this problem. I have tried that, along with repairing disk permissions & restarting, trying to soft reset the bricked iPhone, trying it on a different computer with iTunes.... same result each time, over and over again: "An unknown error has occurred (14)."


I've had problems with updates in the past, but never like this one. There's not even an option to restore to factory settings and start all over again. It's well and truly bricked.

Hey, so...


I screwed up big time, I'll go right ahead and admit that I jailbroke it. First iPhone (4s, 5.1.1), and I was like "I WANNA' CHANGE PUSH NOTIFICATIONS WOOHOO!" Found out Jailbreaking was the only way... (Apple get on that...) I did it, stupid Cydia app didn't work... and I was like... well that's useless.


So I tried going back to factory settings... and it didn't work. Just bricked on me. I freaked out, and everyone said I was screwed minus the few who said restarting the computer would help. I had tried a few times before restarting, and was like... I JUST GOT THIS PHONE NO, GOD, NO! Literally prayed hard... restarted... and voila.


TL;DR - Prayer (And restarting) worked.


P.S. I also really wanted to restart because the keypad for the Phone app was like... cheesy. I'm a designer. Those things freakin' matter.

I was getting Error 14 exactly as stated.. and then I had Error 9 too. Both issues can be USB related.


-= What worked for me: =-


* unplug all other USB device (except my keyboard)

* kill Parallels
no really, kill it.. and all its sub-processes too. I used terminal. Ran "sudo su -" for super access then ran "ps -A | grep arallel", then ran "kill -9 xyz" on all the process ID numbers listed (replace xyz with actuall process ID, but then if you didn't know that maybe you should just restart the machine). I had to go to this extreme as Paralells was not playing nice and was interfering with USB connections AND not shutting down properly.

no need to restart machine

no need to re install itunes

no need to unplug and plug back your iphone cable to machine

no need to return to apple support


just simply go to

C:\Documents and Settings\User\Application Data\Apple Computer\MobileSync\Backup

you will be able to see a several list of back up folders

just cut and paste to drive D: or you can delete it if your really sure the latest back up


to check the latest back up folder just right click the folder / properties and check the date and size of the back up folder


connect the iphone to machine and click restore.


have done this to several iphones


issue RESOLVED


any questions you can email me at danpaul_dy@yahoo.com


thank you
