Hi I bought a R4 (R4i Gold 3DS from http://r4ids.cn) from www.dsflashcart.com like almost half a year ago. Today when I tried updating it, I encountered a problem. This is what I tried to update my r4: I downloaded the latest WOOD firmware (v1.61) and I also extracted the files from the 3DS6.0 patch to the root of my sd card. I got files from the official R4 website http://www.r4ids.cn I used my DSi (v1.4.5U) to boot up the R4 and run R4iGold_3DS60_Patch_NDSi_3DS.nds. Then it asked me to press the A key to start the update. But after I press A, it said "Fail" on Card Check. I tried taking out the r4 and putting back in and pressing A again, but it still said "Fail". I already tried running both update files R4iGold_3DS60_Patch_NDSL.nds & R4iGold_3DS60_Patch_NDSi_3DS.nds but nothing works. I also tried the same steps on a normal DS and got the same results. The R4 card that I have has a DORASU logo (guy with hand) and I think its a revision C chip because it has a letter "C" on the back. Is there anything I can do to fix this problem? I'm trying to update my R4 and get it to work on my 3DS XL v6.1.0-12U. I accidentally updated the firmware without knowing that there was a patch. Thank you.
