Installating Resurrection Remix on HTC One X

I have a HTC One X (International model) and have been trying to install Resurrection Remix as a way to get a more modern Android version. I've unlocked the bootloader and installed ClockworkMod Recovery 6.0.4.8. I cannot get Resurrection Remix installed. I keep getting this error: > Your recovery is using the new storage layout but the ROM you're trying to install is not. > Flash a compatible recovery and format /data and /sdcard or use a compatible ROM. I've tried 6 different versions of Resurrection Remix, the latest one being cm-12-20150228-UNOFFICIAL-endeavoru-big.zip . It explicitly states it uses the new storage layout, though I still get that error. I followed the steps described in this blog post , and I've also been Googling the error. It seems other people have run into it, though I can't find any actual solution. Should I be using another ROM? Should I use an older/different version of ClockworkMod? Is the error wrong and caused by some issue not related to the ROM layout?
