It's not the 3DS that's the issue, it's that your R4i Gold isn't updated enough to bypass the new blocks that were installed. Unless you can use somebody else's DS/Lite to update the cart, you'll need to buy a new flash cart.
im still afraid to update my 3ds to latest fw, does anyone know how widespread the issue with it not working with newest dstwo and 3ds fw is?
also im wondering if it will make a difference if update it with my lite or 3ds ,i usually use the lite , but i heard reports of it not working on 3da after people useda lite to update the dstwo fw, but no mention of anyone who used 3ds to update it,
anyone have a 3ds and a dstwo and are NOT having an issue? or is this just rare issue
