Acekard 2i not working on dsi xl

Hi, I know there have been more topics about this but you are not meant to upgrade your dsi to 1.4 but the xl already comes as ver 1.4ESo that when I press the ak button on the xl the error message shows. How can I fix this other than using another ds. Please help thank you.

Well you will have to run an update on your Acekard 2i on a DS Phat, Lite or DSi with firmware less than 1,4

ok thanks, i'll be able to borrow one tommorow and hopefully it'll work thanks

Here's the guide
