I have been all over XDA and the web looking for how to flash CWM recovery on my i925, so I can install CyanogenMod. Nothing seems to work. I have tried the how to listed here, http://wiki.cyanogenmod.org/w/Install_CM_for_i925 both on Windows and Mac. Does anyone have any guilde, files that can help me acomplish this? Do I need to downgrade the firmware first? Currently on I925VRAMK1.
