I recently acquired a R4i SHDC for 3DS and it's not working... I downloaded the kernel last version but still give me the same error screen. My 3DS is a 3DS 2.1.0-3E, I tried the r4i-sdhc 3ds 1.43b kernel and didn't work...and I'm probably doing something wrong. Step-by-step, what i'm doing is: formatting the sd card, downloading the kernel, exporting in a common paste on my computer, moving the files to the sd and inserting into the 3DS. Have you guys heard about someone else with the same firmware (2.1.0-3E) who manage to work the R4i card? Thanks! thanks for all the help, well, i purchased a new r4i sdhc 3ds from another trustworthy website: http://www.oz3ds.com/product.php?id_product=24 , and the new one works fine.
