So I accidentally updated my 3DS too much (currently at 6.1.0-12U) and my R4 won't run on it anymore. I'm having trouble upgrading the firmware, I do have a DS Lite and I've been trying to use it but it says "Fail" when I press A. Page I got the upgrading patch: http://www.r4ids.cn/r4i-download-e.htm Any help I can get for this? Also does anyone know a good way to open the R4? I know after upgrading I have to cut one line but I haven't been able to find any videos on it.
