Today i bought a R4 Gold PRO 3DS, Model r4i-gold.com...I will describe exactly the steps i did and how i got a permanent white screen that i dont know how to fix... 1. As a new to r4, i inserted r4 without sd and i was getting an error " no system file ~similar to this, i dont remember" 2. Tried many kernels but all of them gave me white screen when i started the cart. 3. Then i downloaded this: 4. It worked but when i tried to play a game, it stuck at loading and i restarted the ds. 5. After restart iam now getting a white screen when i run the cart, even without a microsd inside. Yes,i reformated sd and also tried a second sd. Iam using NDSL.
