thanks for the link but thats what i found the instructions on and had no luck.this is what i followed -FIXING SOME ISSUESUpdating Acekard to Work on DSi Firmware 1.4.1 (with pictures)
You WILL need either a Nintendo DSLite or a Nintendo DSi with firmware 1.4 (flashcart has to be updated to work on 1.4 to update on DSi 1.4) or lowerQuote
1.Download the files needed to update: AceKard 2i firmware 1.4.1 - Direct Download2.Extract, you get to files: ak2ifw_update_141_DSi.nds (if using a DSi) and ak2ifw_update_141_DSL.nds (if using a DSL)3.Copy the one you need to the root (start) of the sd card4.Plug your DS(i) to the charger (to avoid any problems if DS runs out of battery while doing the update)5.on the start of the AKAIO menu, look for the file you copied and press (A)Spoiler (click to show/hide)6.Start menu shows, read precautions. once done press (START)Spoiler (click to show/hide)7.Wait untill the progress bar reaches 100%. It will take a few minutes for this to finishSpoiler (click to show/hide)8.Once the Progress reaches 100%, it will tell you to reboot the DSSpoiler (click to show/hide)i updated the card on the DSlite to hopefully get it working on the DSI, was i right to put the DSI file from the rar on the card and run that on the DSlite?

no you should have used the .nds file.
