I have the same issue, any update?
Does anybody tell me what Kernel update work with the r4i gold for nintendo DS 3D / 2.1.0-4U? I install the WOOD R4 V1.35 but the NintendoDS 3D give an error.
The Nintendo DS 3D has the version 2.1.0-4U
Finaly I update my r4i card with a patch.(3DS20_Patch_R4iGold_3DS_NDSi.nds /3DS20_Patch_R4iGold_3DS_NDSL.nds ),Download from r4ids.cn, Follow the instruction and go to play again.
You need a DSi, DSXL or DSL to update the flashcard.
