Trouble updating ipod touch to 4 3
Restarting an i Phone, i Pad, or i Pod touch is just a matter of Holding down the Power button and Home button simultaneously until the device restarts.
Technically, that approach is called a Hard Reboot because it forcibly restarts the i OS device, but in situations where things are acting up, crashing, or just not behaving properly, it’s usually more effective to force reboot than to use the standard power-off approach.
Sometimes this is enough to get things working again.
If i Tunes won’t even find an i OS device, refer to this guide to resolve detection related problems.Both ways work basically the same, so it’s really a matter of preference as to what you choose.Resetting and restoring is the last troubleshooting step you should take yourself, and if things still are not working properly then go ahead and contact the official Apple support line or visit a Genius Bar to get things sorted out.Before trying anything else, be sure you have the newest version of i Tunes on the computer. Sometimes just updating to the newest version of i Tunes 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 i Tunes directly from Apple by clicking here. Simply quit out of i Tunes, then relaunch the app, and try syncing again.
