Yes. To do so, you will need the original firmware file. If you have it, plug in your iPod and hold down the sleep and home buttons on your iPod until the screen goes dark. Then, let go of the sleep button but keep holding the home button until iTunes recognizes the iPod. From here, hold down the shift key and click on the restore button on iTunes for your iPod, and select the 1.1.4 firmware file when prompted.
