Recently, I bought a 3DS. I had a NDS Lite at the time and 2 R4's. One was an R4i-SDHC and the other one an R4i3D. Both of them worked just fine. After I got my 3DS, I decided to plug the R4i-SDHC in. It worked but maybe because I didn't update it. With my consent, my sister updated the 3DS to ver 3.0.0-6U. We tried the R4i-SDHC and it didn't work. We tried it on the NDSL, it still worked. Then we downloaded the kernel on this website: http://www.r4i-sdhc.com/ We extracted it on the MicroSD. We tried it again but this time, when I press a button when the 3DS is on, it freezes. And if I put the R4i-SDHC in before I turn it on it wont start up. I borrowed my friend's R4i-SDHC, his worked fine. But when I tried my R4i-SDHC, it froze for him too. Now I only play uisng the R4i3D on the NDSL because the R4i3D doesn't work on the 3DS. What can I do??? I also tried on my Lite after the kernel update, it freezes the DS Lite too!
