Now when you say to just flash the lockscreen, do you mean this http://nabzilla.googlecode.com/files/CM-4213_CHM_BinaryReleaseLockscreen.zip ? Because I did and that does not help
Well... I'm not a coder or a rom dev so somebody else will have to take a look at your logcat because it's greek to me. Thanks for providing it though.
Did you go back to a pre-theme state (regular rom with no theme) and then flash the lockscreen mod?
If you've done that then it's not the modified apps in the theme and it eliminates possible problems. However just flashing the lockscreen mod over the theme that isn't working for you will more than likely not resolve your issue. The lockscreen mod is nothing but slightly modified jar files in the framework folder and a modified Settings.apk file. That is all it is. No apps are changed.
So if you flash back (or restore back) to the Cyanogen Rom 4.2.13 and then try flashing the lockscreen mod. This will give you most of the theme with exception of the launcher of a couple other modified apps HTC system apps.
