Last night, I updated my DSi to the 1.4.5e firmware version. This, as I expected, caused the card not to work and bring up the error screen: Code: An error has occurred. Press and hold the POWER Button to turn the system off. Please refer to the Nintendo DSi Operations Manual for details. This morning, I put the latest EOS files plus the "dstwoupdate.dat" file on the root of my TF card. I have also tried replacing the "system11.dat" file in the "_dstwo" folder. This has done nothing. Do I need a non-updated DSi or DS to let the card update itself? 1 other question: How do I tell the difference between a Chinese card and an English card?
