Thank you in advance.
.odex? was that a typo? Surely your CM rom is de-odexed?
The file size sounds right, so assuming you did that correctly and pushed the apk to /system/app with adb; the next best thing to check would be that you have set the permissions of the apk to 644.. for example:
->chmod 644 /system/app/NfcNci.apk
If that doesnt solve your problem, Im not sure that I can help without trying it out for myself. Also, make sure you have copied the classes.dex to and from the right apks and them pushed the original apk back!! Its easy to mix them up!
