R4 SDHC Firmware

I've been trying out all the firmware for the 8GB R4 SDHC, I must say, the only valid version that functions is the 1.21. I have tried all the latest ones and they only give you a purple screen.Anyone have a fully functional latest version firmware? I can say that they (people of R4 sdhc) only keep releasing crap firmware that barely function or have glitches and bugs galore.

1.23 seems to work from http://www.linfoxdomain.com/nintendo/ds/.

Nope, it's another purple screen crappy firmware that someone hasn't taken the time to test. Unreal.... the only functional firmware for the R4SDHC is the 1.21....... and it can use an update.

Cannot get any SDHC Firmware to work on mine. Just constantly showing up as "loading"
