Unknown sync error -- Tried everything (?)

I've recently switched from Chrome to Firefox to try and get as far away from Google as possible. There, I never had any issues with syncing across devices and platforms.
On my Windows desktop, syncing never fails. On my MacBook Air, it always says, along the bottom of the window, that an unknown error has occurred.
I did have the Keychain Services Integration add-on installed, but removed it because I thought that that might be why. Still, I get an unknown error. I removed *every* Firefox-related file on my MBA and got everything going again (minus that add-on), and it still throws an error. I also tried deleting the profile and creating a new one, resulting in the same error. Lastly, I tried the PlacesCleaner add-on, also with the same results.
I'd attach a sync log, but it seems like some of what's in it might be private.
Any ideas?

You could '''Unlink''' that MBA from Sync, then restart Firefox on the MBA and then re-connect to your Sync account, to see if that helps.
There's no private information in Sync error logs, but most of those logs contain more characters that these "Post a Reply" boxes can handle and the formatting might not carry thru when posted.
In the second column of the Error log look thru the '''Sync.Status''' items for the first listed ERROR; subsequent ERROR listings might be of interest. Also, any '''Sync.ErrorHandler''' lines might have information we can use.

From your statements above, it sounds like you never tried to burn a CD for at least the first year that you owned the laptop, as it had a one year warranty on it. While you might have used it frequently to install software, play DVDs, Blu-Ray disks, etc, that's unclear from your statements. Nonetheless, it might just be dirty-dusty. So, before deleting-uninstalling any software, and given they're cheap, try a CD-DVD Cleaner Disk first and see if that resolves your problems.
Let us know what happens. Good luck.

Just can't sync. Tryed everything.'

Just can't sync. Tryed everything.

Why not? What happens when you try? Is your iPod not recognized by iTunes? If so, have you worked through each and every troubleshooting suggestion in this Apple support document?

I had the "unknown syncing error" for so long with no improvement that I finally uninstalled Firefox sync--but I'm STILL getting the error all day long!!!!

Running Firefox 4.0, was running Sync 1.7 on a Windows XP machine. Became so frustrated with the constant error message at the bottom of my screen (Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action.) that I uninstalled Sync. However, after multiple Ff restarts the error message continues to appear.
I noted that at least 10 other people had posted this as a problem in the forums but didn't see any solutions.
Can you help?

I know the last reply was from a couple weeks ago, but honestly, I haven't been able to find anything else in the last week of searching Google. I'm new to the MDT process but I'm having the same issue with what you posted. I can shift-F10 during the "Applying
system settings" and open my unattend.xml file and remove the IEWelcomeMsg line and the image deploys perfectly, so I know that's my problem. I can't figure out where that line is coming from. I have edited every unattend.xml file in the Templates folder under
MDT and also the one in my deployment task sequence, but somewhere during that deployment, that one setting gets added back to the unattend file and nukes the whole image. I'm about to pull my hair out. I'm implementing MDT to save time but I feel like the
last couple of weeks trying to get it to work have been a waste. I have thought about backing my reference image back to IE9, but having to deploy IE10 post image seems like it's an unnecessary burden. Any help would be appreciated.

Illegal character \92 error.Tried everything

Hi, Im trying to make a calculator program and in the line where I divide a by b, im getting an Illegal Character:\92 error for some reason. To type \ im using \\ as an escape character, and it seems to work earlier in the program with no problem.
Heres the code:
import java.io.*;
public class PA83 //Simple calc
    public void calculator()
        try
            InputStreamReader isr = new InputStreamReader(System.in);
            BufferedReader br = new BufferedReader(isr);
            System.out.println("Enter number 1");
            double a = ((double) br.readLine());
            System.out.println("Enter number 2");
            double b = ((double) br.readLine());
            System.out.println("1.Add\n2.Subtract a-b\n3.Subtract b-a\n4.Multiply\n5.Divide a\\b\n6.Divide b\\a\n7.Quit");
            int c = Integer.parseInt(br.readLine());
            switch(c)
                case 1:System.out.println(a+"+"+b+" = "+(a+b));
                break;
                case 2:System.out.println(a+"-"+b+" = "+(a-b));
                break;
                case 3:System.out.println(b+"-"+a+" = "+(b-a));
                break;
                case 4:System.out.println(a+"x"+b+" = "+(a*b));
                break;
                case 5:System.out.println(a+"\\"+b+" = "+(a\b));
                break;
                case 6:System.out.println(b+"\\"+a+" = "+(b\a));
                break;
                case 7:break;
                case default:System.out.println("Invalid Option. Please select a number from 1-6");
                break;
        catch(Exception e)
            System.out.println("Error: "+e.getMessage());
}              It highlights case 5 and gives me an illegal character:\92 error, but ive used the double slashes(\\) earlier in the println to choose an option without any problem there.
I dont understand why this is happening! Even if i remove the "\\" i get the same error , and as BlueJ suggested, i tried typing the line again to avoid some invisible character causing problems..

Hi,
I think we use "/" for division and not "\" .
thanks & regards,
Manoj

Ituens doesn't open. qtcf.dll error. tried everything

I updated my itunes and now I'm getting that all too popular wtcf.dll error.
first I tried to repair quicktime. nothing worked
I tried to reinstall itunes.
I uninstalled ituens and instaled it again
I uninstalled quicktime and installed that again
I downloaded a qtcf.dll file from thei nternet and put on my desktop, in the Windows foldar, and also in the system32 folder.
nothing has worked so far. I also get a startup error too related to ituneshelper.exe

I downloaded a qtcf.dll file from thei nternet and put on my desktop, in the Windows foldar, and also in the system32 folder.
Let's first remove those three files, tidus. Having a QTCF.dll lurking about in unorthodox places on the PC can actually cause errors.
I also get a startup error too related to ituneshelper.exe
That suggests you're getting a rare version of the QTCF.dll error caused by a damaged Apple Application Support. (If AAS is broken, sometimes iTuneshelper isn't able to launch either.)
Let's try the procedure I suggest to fizzylove in the following thread:
http://discussions.apple.com/message.jspa?messageID=10918603#10918603
Does that help with the QTCF.dll?

Error message withg sync, tried everything, nothing helped. Please help me.

Gets error message "Attempting to copy to the disk "Ipod" failed. The disk could not be read from or written to". It will put on about 15-30 songs before displaying this message, and can fully sync but it takes forever because i have to press "ok" than "sync" every 15-30 songs. already tried to send it back for a warranty replacement but they said there is nothing wrong. i tried everything, restored, zeroed out ipod disk, reloaded itunes, and all over again about 10 times

Ran into the same error message while attempting to synch an iTunes purchased movie to my son's 5th Gen Video iPod from my G5 Tower (OSX 10.4.11). Here's what worked:
Restored his iPod to factory settings. Noticed that this included having the iPod enabled for disk use (this box was not checked previously -- when we were getting the error message). Reselected which playlists and videos to synch, applied the synch settings, then waited (with crossed fingers and a few prayers to boot!). It worked. No error messages.
Note: the iPod synch cable is plugged directly into one of the USB2 ports on the back of the G5 tower -- not into one on the 3rd party PCI expansion cards I installed to add more USB2 & Firewire ports (not sure if this is relevant, but it seems so based on your discussion thread here). Hope this helps.

My iTunes account says error 13019 after it has recognized all of the music and I have tried everything that is on this website and everything i can find about how to fix it; I even created in under a new administrator. Any suggestions how to fix it?

My iTunes account says "The iPod "Madison " cannot be synced. An unknown error has occured (13019)" after it has recognized all of the music and has went through every song and it said "Copying (song) to "Madison"....." and then after it has went through all of my songs (492) it says the error message. I have tried everything that is on the Apple iTunes website about it, I have created the music account under a new administrator, I've tried everything. What do i do?

I found something that worked. I had never come across "recovery mode," but found reference to it, how to do it. http://www.ichilton.co.uk/blog/iphone/getting-the-iphone-ipod-touch-into-recover y-mode-48.html
Put the ipod touch in recovery mode and then restored it, setting it up as a new Ipod, rather than restoring from the backup. Given how much trouble I'd had, I suspected that the backup might be corrupted anyway.
That seems to have resolved everything completely.

I just tried to update my iphone 4 to the 5.01. My iphone backed up and started update but now its stuck in recovery mode and will not restore. It gives me an error message of 1, but I have tried everything on troubleshoot list and still wont work!!!!

Syncing Ipod Touch 2nd gen to Windows 7 PC. i have tried everything.

Okay so, i've been using my Itunes for about a year now, without using any apple device, just so i could listen to music.. My sister gave me her Ipod touch 2nd generation yesterday. It was connected and synced to a different library but i thought that my Itunes was at least supposed to recognize the device? i want to sync it with my library, even if that means i lose all the media and data on it now.
My computer doesn't even recognize the ipod. When i plug it in it says it's charging, but the Device Manager has no "Unknown Device" or "USB Mass Storage Device" or even "Ipod". It doesn't have a title even relevant to the ipod.
I've tried everything on these two articles. None of it works. V Help, please!

I have been trying for about a month to get my Touch to sync with i-tunes. I have already used up my "1" support from the technical center and I think apple is a bunch of a$$es for not supporting this product better. They change the OS for i-tunes and then nothing works afterwards....Lame! If anyone finds out how to repair this issue please let us know, Apple is of no help to us. I'm glad windows has something out now, time for something new on the Christmas list !!!!!

I just bought the iPhone 5 and I tried to sync it to my itunes but it wont sync.. I tried everything!

After several attempts to sync my new iphone to my itunes it still does not work. I have tried everything including deleting and reinstalling my itunes but nothing works. Nor does syncing from my phone! What can i do to fix this ?

I FIGURED IT OUT. THANK FREAKING GOD!
This is what I did:
I went to control panel and unistalled iTunes completely, then I installed 10.6.3
http://support.apple.com/downloads/#itunes which you can find here
It came up with an error saying that my library had beed used with a more updated verision, basically had to upgrade. I installed iTunes 10.7
After it had installed and iTunes was running I hooked up both my iPhone and my flash drive, I have more than 1 usb port I figure most computers do now, and by the time and date in the bottom right corner a small icon came up showing that I had devices hooked up. It showed both my iPhone (but did not know what it was) and my flash drive. If you right click on the iPhone it has the option to Troubleshoot it. I did it and my iPhone 5 now FINALLY SYNCS!
I'm sooo happy now.

Try runing iTunes in admin mode. That fixed the issue for me. You can either right click on the shortcut on your desktop and choose to run as an admin each time you launch it or go to the advanced tab under security on the program itself and click the run as admin every time.
