Hi All, I have an R4i-SDHC 3DS RTS that I cannot upgrade the kernel on because it does not give me the option. It tells me the current version is "Support Model: NDSL, NDSI 1.45, 3DS 4.5" and underneath that there is no upgrade option. I put the latest files on my SD card (ver. 1.74b), but I still get no upgrade option. I'm trying to upgrade this on a DSi on version 1.4.1U. Does anyone have any suggestions to upgrade the kernel? I wrote firstname.lastname@example.org and they told me that some cards are not supported. I thought all RTS cards are supported. How do I tell what version I have and if it is supported for the latest kernel? Thanks in advance.
