hmmmm, not sure on that one. but i don't think RZR's latest version is available as a recovery.img file - i think you might need to flash it as an update.zip. his current version is 0.1.7, i believe (and working on 0.1.8). dl that to sdcard, rename it as update.zip, go into RM and "flash alternate recovery", boot into SPR, and install. then reboot and see if you can't it to flash for you that way.
