I have the DSi XL and iEDGE card. All was fine until my son updated the firmware to 1.4.2U. The iEDGE card was on version 1.11. I would get the message "An error has occurred. Press and hold the Power Button to turn the system off....." I attempted to update the card but got the same message. Here are the steps I took. 1. Downloaded iEDGE Boot Update v4 and the required ROM file. 2. Format Micro SD card with FAT32. 3. Successfully ran EdgeBootUpdate. 4. Verified bupdate.bin file is located on Micro SD card. 5. Put SD card into the iEDGE and put the iEDGE into the DSi 6. Turned on the DSi. 7. Went to the iEDGE card using the normal method. (select soduku). I always get the same message - "An error has occurred. Press and hold the Power Button to turn the system off....." Anyone have any ideas?
