Turn off lost mode on internet-less ipod?

Hi!

My iPod 5th gen, 16 gb, ios 6(?) which is not connected to the
internet, was lost.

To find it, I turned on lost mode via icloud.com on the computer.

However, lost mode only works once the iPod is connected to the internet;
thankfully, I found it anyway.

My problem is that my iPod is currently disabled because I had turned on
lock mode, but now I don't know how to disable it (i.e. turn OFF lost mode)
through the computer WHEN THE IPOD IS INTERNET-LESS.

Furthermore, I am unable to enter the passcode of the iPod.

What can I do (without resetting the ipod) to fix this problem?
