Display locked after trying to sync

It's a common issue. You can follow below steps to fix it.

Before trying to fix the iTunes error with some methods, you need to be sure you have the newest version of iTunes on the computer. Sometimes just updating to the newest version of iTunes is enough to resolve all syncing problems, particularly if the desktop software hasn't been updated in a while. You can always download the newest version of iTunes directly from Apple. After updating to the newest version of iTunes, if you find that your iPhone still won't sync with iTunes, you can follow the tips below to fix the error.
1. You can simply quit out of iTunes, then relaunch the app, and try syncing again. Sometimes this is enough to get your iTunes working again.
2. If syncing fails, the Sync button is greyed out and not available at all, or if you try to sync and nothing transfers over to the iPhone, iPod, or iPad, you may simply need to authorize the computer with iTunes.
3. You can also try restarting your phone by holding down the home button and power button.
4. Sometimes just restarting a Mac or PC is enough to resolve the problem and get things syncing again.
5. Typically use Wi-Fi Syncing? Try using a USB cable instead. Usually use a USB cable? Try using Wi-Fi syncing instead to see if that works.
6. If you find wireless sync to suddenly stop working, you typically just have to toggle the feature on and off again to get it functioning again.
7. Sometimes USB ports go bad, and though it's pretty rare it's very easy to rule out. All you need to do is switch the USB cable from one port to another and see if it works.
8. Reset and restore the iPhone. This should be your last option. You will lose all the data on your device. You will be resetting your phone to factory settings and start as if its a new phone. Only advantage is that you have iCloud backup.

Take the new router back to where you bought it and get a different router. There is a problem with this router.

[Extra Hardwares Needed] 1. MicroSD card 2. "Micro-B" USB data cable
[Procedure - either PC or Mac] 1. Disconnect USB cable (if you connected already) 2. In Xenon phone Settings -> More -> Connection -> USB Connection -> (select) Mass Storage Note: If you don't do this, you will get an error message "Unable to use liscense. TRy again after formatting memory card." 3. Insert MicroSD card into Xenon phone slot 4. Connect Xenon phone to PC (or Mac) using USB cable 5. If MicroSD is not accessible as a disk drive, then (1) remove the MicroSD from Xenon (2) format the MicroSD from PC (3) retry step# 3 & 4 6. You can drag & drop your folders and/or files (.mp3 or .m4a only) into the MicroSD card 7. Disconnect Xenon phone from PC then go to "AT&T Music" -> "Music Player" Note: All features work except for "Playlists" 8. If you want "Playlists", you need to use Windows Media Player and sync. iTunes doesn't work since it doesn't allow other devices than iPod. This means that you cannot use Mac to create/sync the playlist.

try to reinstall the software...sometimes taking it out and in again works.

Try changing 'Settings - Connectivity - USB connection' from 'Mass storage' to 'Data service'. I think that'll work (you'll have to change the setting back again if/when you want to copy files again. :-)

Hi there,

I had the same problem with my N95, what I did was try another USB cable, and was able to complete the data transfer and have my phone show up as a usb drive when connected.
Hope this helps!

I have an LG 970 with precisely this stupid problem. In many, many ways, this phone is a complete nuisance. This particular stupidity is a phone setup issue, it cannot be a Mass storage Device and a Data Service at the same time.
Solution:
Phone, Menu, 9 Settings, 4 Connectivity, 3 USB connection, ...
- select "Mass storage" if you want to access images, sounds etc using Windows Explorer, just like any other USB stick
- select "Data service" if you want to use the LG Mobile Sync application

I have the same problem like everyone else in this forum! here is the solution:

1. The USB modem driver came with the CD may or will not work, so get the latest drivers for it.

2. Before install the new drivers, change your phone setting under " setting -> USB connection -> from MASS STORAGE to DATA LINK.

3. Plug the usb cable to the phone and to your PC, it should do anything or give any message if it does just cancel it for now.

4. Install the new USB driver you just download, while install it will said something like " does not work with XP " just click OK don't panic.

5. After it finished installed you will see by the clock that it find the USB LG blah blah...and ding ding sound if you have sound on.

6. Now go back to LG Sync software and click on Connect & choose LG modem com port whatever it there.

7. You're done !!!

Here the link where to get the new USB driver:

Good Luck!
