How long did you leave it after the reload finished before pulling out the battery? Sometimes it takes 5-20 minutes or longer for a device to initialize (or show the egg timer/hourglass) before it will come on, and pulling the battery in the middle can cause corruption of data on the handheld which prevents it from loading properly.
If it is still hourglassing today, you might have to wipe and reload again, but this time give it a bit of time.
