I think I forgot to wipe my cache and something else when I installed Cyanogenmod 7 - which I could reboot into just fine. However, when I went to go back and switch to my vanilla Optimus 2X backup (using the ClockWorkMod Recovery - backup, not advanced backup), I reboot and I get the LG loading screen with the police-line loading bar, but after a couple of seconds that loading bar stops moving and the whole thing is frozen.
So, I take out the battery and go back into ClockWorkMod Recovery using the Vol Down + Power shortcut (which only works in about a third of the start-up attempts, for some reason). Where can I go from here to restore to a factory-reset version of the Optimus 2X's 2.2 Froyo?

If, in CWM Recovery, I clean the cache and wipe user data, then install CyanogenMod7 from .zip again, it boots and runs fine.
