If your iPod is disabled, the only way to unlock it is to completely erase and reset it. If you have a backup, you'll be able to restore it, otherwise you'll lose all of your data. There is no way to unlock a disabled iPod unless you use the correct passcode or you erase it. If you don't have a computer with iTunes, see the next section for instructions on resetting your iPod using the iCloud website. You should see your iPod listed at the top of the screen. If you are asked for a passcode after connecting your iPod to your computer, or you've never synced your iPod with iTunes on your computer before, see the Using Recovery Mode section below. This will allow you to restore your data after you reset your iPod. Make sure "This Computer" is selected to create a complete local backup. This will likely take a few minutes to complete. Once the reset process is complete, you'll be taken through the iPod's initial setup process. This will load the backup that you created so that all of your data is restored.

This first step will remove most dirt and grime from your wheels. This will allow you to recognize any dents, chips, or rust on your wheels. It will also make sanding easier and more efficient. A wax and grease remover is typically just a nonpolar solvent like mineral spirits (unlike water, which is a polar solvent). This will dissolve things that water will not, such as oils. It's a good way to clean what your soapy water may have missed. At the very least, you will need a wire brush to remove all rust. Ideally, you would sandblast your wheels to remove rust and any old paint or stuck-on debris. This will give you the best starting surface. Next, sand the entire wheel with 300 grit sandpaper and then 500 grit sandpaper. This will remove any coarse scratches and leave only a smooth surface with very fine scratches that the paint can adhere to and cover. When you are finished sanding, you should be able to run your fingers over the wheel and feel a smooth even surface. There should be no rough patches or pits in the wheel. You want to spray off any debris from sanding. Remove as much dust as you possibly can. This will help ensure a clean paint job. If you do not have a water hose, you can dump water over the wheels with a bucket. Use compressed air to get to any cracks or crevices that you cannot reach. Make sure that all water (and the dust in it) is wiped away. Again, we want the wheels absolutely clean for priming and painting. You can also dry with a chamois cloth, but be sure to leave no water on the surface at all.

At this point, your petit fours are essentially done, but you can decorate them even further to match the theme of your party or event. A quick and simple decoration would be to pipe little rosettes on top of each petit four. You can also use sugar candy shaped like flowers instead, or drizzle melted, colored chocolate on top. Other popular designs include polka dots, strips, and bows.
