So I bought from a reseller that was listed on www.r4i-gold.com For a FYI I have bought from here before, the exact product and it worked flawlessly before (two different times) This time I decided to buy 2 more of the same brand, R4 Gold Pro 2013. When I first received the card(s) I popped the card(s) into my 3ds with firmware 4.5. and it loaded up but it would white screen. So I decided to upgrade the firmware and kernal to the most recent on www.r4i-gold.com. After doing so on my 3ds, it changed the icon to spongebob and then it decided to give me an error after loading that I needed to reboot. So I tried it on my other DSi XL with firmware 1.45 and it said the same error... I borrowed my neighbors DS lite and it loaded up, when I tried to play a game it gave me white screen. So I decided maybe I should reapply the firmware(on the ds lite), every time I try this with the newest 6.20 firmware the screen loads up and says I already have the newest firmware, and it doesn't let me apply the update. I swapped kernals tons of times and nothing works. At this point the only thing that I could see that might work is somehow get a modified firmware that allows you to flash the r4 card regardless of what firmware is on the card already. AHHHHH!
