How to Fix an iPod Touch Stuck in Recovery Mode With a Free Program
An iPod Touch's "Recovery Mode" is for alleviating major operating system issues. Recovery Mode rolls back your iPod's operating system, stripping problematic updates and downloads from the unit. The goal of this total system recovery is to revert the iPod to a stable, usable version. Before you use Recovery Mode, exhaust other troubleshooting methods. In some cases, Recovery Mode is triggered automatically after a failed system update or system restore. When it goes into Recovery Mode automatically, you cannot use your iPod until you complete the recovery process. You can get your iPod Touch out of Recovery Mode using Apple's free iTunes software.

Things You'll Need
-Apple iTunes-USB cable


Instructions
1 Turn on your computer and open iTunes. If you are prompted to download any new iTunes updates, install the updates before proceeding.
2 Plug an iPod USB cable into your computer. Do not plug the other end into your iPod Touch yet.
3 Turn off your iPod Touch. If the iPod Touch is already shut down, skip this step.
4 Press and hold the Home button on your iPod Touch, and plug the other end of the USB cable into your iPod Touch.
5 Release the Home button after you see a white USB icon and the iTunes logo appear on your iPod Touch's screen. At this time, a pop-up should appear on your computer screen, explaining that the software has detected an iPod in Recovery Mode.
6 Click "OK."
7 Click on the iPod Touch from underneath the "Devices" heading on the left-hand side of your screen.
8 Click on the "Home" tab, and then click "Restore." Once it's restored, your iPod Touch goes out of Recovery Mode and you can start using it again. The restoration process takes a few minutes. Do not disconnect your iPod Touch until a prompt appears, letting you know the system restored successfully.

In order to get rid of the forgotten code and disabled message, we must restore the device.

In this case when the iphone or itouch or similar is giving you a message that its disabled, then we have to first force the device into recovery mode, from which we can do a normal restore.

4. While still holding the home button, until you see a message about "Connect to Itunes" then let go.

5. if not already open, open itunes, you should receive a short warning about recovery mode.

6. do a normal restore from itunes, it wipes the devices and the disabled message and the forgotten code are removed.

I recently had a similar problem, and nothing I did helped; what I eventually did sounds pretty simple and possibly won't help ( I have a feeling that it might have been a USB port issue, more than anything). I have added the description of my problem below my 'solution'.

I disconnected the player from my PC, restarted the PC, disconnected & reconnected the battery from the Muvo2, turned the player on (just to check if it was reading the music) then turned the player off. Then (with the Muvo2 powered off) I reconnected the player to the USB cable; the darn thing was recognised immediately and was working fine...

My problem:
The player was working fine, Windows (XP Pro) recognised the device as a Muvo2 & I could transfer files no problem; I clicked on 'Safely remove hardware' and removed the player. However, when I now try to reconnect the payer Windows gives me an error message, that one of my USB devices failed to connect and that it doesn't recognise the device. It suggests reconnecting, which does nothing...

The Muvo2 screen displays the 'connected to computer' image. If I disconnect using the 'Safely remove hardware' and unplug the cable, the player display says I need to connect to my PC and run scandisk. I can't get the computer to recognise the device, so I can't run scandisk. Removing and reinserting the player's battery got rid of the 'Scandisk' message & the player worked again, but it's still not connecting to the PC.
