Hi, this title maybe wouldn't explain at 100% what happened, so i will explain here... Yesterday i tried to upgrade the r4i (r4i 3ds wifi v.4.4) on my old dsi xl that has the version 1.4.4e (that has the touch screen broke) on my other dsi xl (1.4.5u) that is perfect.On the "games" screen i selected firmware update and it started; gone for awhile and my ds just shutted down by itself; when i turned on it goes all fine but starting the r4i there was the "An error has occurred" problem. If you can help; then please answer. Thanks in advance.
