Yep. I updated my DSi XL back in September 2011 to 1.4.3E and since then my R4i-SDHC 1.4.1 has never worked. I updated the R4 (manually, via USB) when the 1.56b update came out two days ago with the hope that it would be working again. No such luck. So today I learned after all this time that DSi XL accepts WPA2 security and updated the DSi XL to 1.4.4E in the hope maybe the R4 will work again. It still doesn't work. I've read the suggestions of updating via a DS Lite but I don't have any unsecure/WEP networks nearby. Do I need to buy a new R4 (such as R4i 3DS)? Thanks in advance.
