So my little brother got a DSi with firmware version 1.4 for Christmas. I bought an AceKard 2i from DealXtreme. When I received the AK2i I determined that I needed to use a DS Lite to upgrade the AK2i in order for it to be compatible with his 1.4 fw DSi. I obtained a DS Lite, copied AKAIO 1.5 to a 2GB PQI MicroSD card as well as the DSL and DSI files to update the AceKard, inserted the microsd card to the AK2i, inserted the AK2i to the DSL Lite, loaded the AceKard, got to the AKAIO menu, selected the DSI update file, I got to the black screen telling me that the process could potentially harm my AceKard and to press Start to begin or any other key to quit; because there was a GBA game inserted to the bottom of the DS Lite, I decide to press A to not commence the process so that I could remove the GBA cartridge and run the update without it inserted later, after pressing A I was told that the update process did not begin and to reboot the ds lite. At that point I turned it off using the switch on the right side, removed the GBA cartrige, and turned the ds lite on, I got a message like "system file is missing" upon boot, I then tuned it off again and turned it back on. This time the DS Lite got to it's menu, I pressed A on the AceKard icon, and the ds lite froze on the "loading" screen. I then turned the ds lite off. I decided to format the MicroSD card and copy the AKAIO files and update files to the MicroSD all over again, figuring something must have gotten corrupted. With the newly copied files in the MicroSD card I inserted the AK2i into the DS Lite and again the ds froze at the "Loading" screen after I selected AceKard from the DS menu... I formatted again, this time I copied original firmware and again, I got stuck at the "Loading" screen. I decided to try the process on a 4GB Sandisk MicroSD using original firmware from the get go and the AceKard Menu loaded this time, and I ran the AceKard update successfully. I confirm that the AceKard now works on my bro's DSi but the problem is that my 2GB PQI MicroSD no longer is able to load official firmware or AKAIO... I've only tried original fw on the 4GB Sandisk, for fear of AKAIO 1.5 somehow causing damage to my microsd card. The PQI microsd works with every other piece of hardware I own though. I've formatted it countless times using both the Windows format utility and the Panasonic one in both FAT(16) and FAT32 to no avail of it working in conjunction with the AceKard... So does anyone have an idea why my Acekard 2i will no longer load from my PQI 2GB MicroSD card???
