My DSi was updated to 1.4.5 by "someone" and now my R4i SDHC Revolution(R4i.cn) doesn't work, I just get the error that asks me to power it off. It seems like the firmware only goes to 1.4.3 according to the download list here: http://r4i.cn/download-en.htm The top one says 1.4.3. Are there any other firmwares for it? I have access to a DS Lite that hasn't been updated since like 2009 or before. Any help is appreciated!
