Can't use R4dsixl3d with DSiXL

I accidentally downloaded an update for the DSiXL and my R4dsixl3d no longer works. I'm aware that it isn't the best flashcart and it would be in my best interest to get a new one, but is there anyway to make it work on a DSiXL with version 1.4.1A firmware? I've downloaded the latest firmware and kernal from the official site but to no avail. Could I be doing something wrong? The site is fairly vague, any help is appreciated.

You made a mistake, bro. You should update your flashcard first, then update the DSi later. Now you need to take another DS or DSi to update your flashcard first, then it can work again. by the way, which r4 card do you have, what is the official site of your card.

All of the answers are in my original post. I do have another DS I can use.
