How to fix DSI error code 0000FE00...

This process does NOT require you to open up the system. The first thing you do is take out the battery and leave it out for about 4 hours. After about 4 hours, put the battery back in. Now try using your DSI/DSI XL for a while and see if it keeps working. If it freezes, reset it. If you get blank screens and/or error code 0000FE00 again, do the following process: Take the battery out for about 4 hours again, then insert an SD card for backup data. Put the battery in, then it's up to you to backup all the data that you can before it crashes again. If it crashes before you backup all the data that you want to, repeat the process again then backup the rest of the stuff. Now it's time to fix it. If it up and running still, then take advantage of that time and format the system memory. This will reset the entire DSI, so that's why I reccomended making backup data. When you turn it back on, it will act like you just bought it. Go through the system setup, then put your backup SD card back in. Copy all your backup data back onto your DSI, and done. If you don't know how to backup your data, let me know.
