Also here is ODIN OC1 firmware you can download and keep handy, install with Odin, when you come from NC2 to OC2
then you can install the recovery flashable OC2 firmware, you see the OC2 recovery installer is like OTA, it patches the OC1 firmware so if your firmware is NC2 then it will not do patch , I need to upload the NON patching OC1 firmware because it is whole files and not patches

Thanks for that. I was wondering why the firmware flashable for OC2 would say that it couldn't do modem.bin or NON-HLOS.bin. After applying the OC1 modem flashable it would still say it couldn't patch NON-HLOS.bin. Applying the firmware with Odin then applying the patch in SafeStrap fixed that right up. Wouldn't want to walk around with an updated 3G firmware but an out of date LTE firmware.
Also after much work and wearing of my flash and NAND, I got the ROM to work fine with Xposed and no force-closes in Samsung apps. I did both the ROM and Xposed flashable in the same instance, rather than letting the phone setup, then installing Xposed. It should work with the SafeStrap menu mod also. I'm thinking it should go in this order: ROM -> SafeStrap menu mod -> Xposed flashable, in order of flashing, with no reboots in between.
Double edit: Also I frequently get problems where it'll be booting, then it'll say that the system is not responding, with the standard popup, and a black background. I can click "wait" or "ok" and it'll receive my touch, then it'll soft reboot ~10 seconds later if I click OK. So far it isn't as annoying as the "getAudioPolicyConfig" logcat spam that I was having on OC1, which wouldn't allow me to boot with anything plugged into the USB port.
Triple edit: Also I suggest everyone install Liveboot, so you can see what is holding up your boot process or if any errors are happening. You might see some nasty warnings or errors relating to Xposed, but those should pass as that's what allow Xposed to work on our phones.
