I only use Clockwork, it must be able to install through SPR if you guys have done it, but I seem to recall something about update.zips not being compatible with SPR, or they had to be renamed or something like that..... I could be wrong... I usually am .....
Anyway, I apologize if I gave misinformation..... sorry guys......
It's actually the other way... SPR needs the .zips to be named update.zip, whereas ClockWork can install the zips from the sdcard in anyname.zip
