1. Can I change the CSC to another region so I can update to 4.4.2?
2. Will Knox 0x0 be tripped if I do so?
3. (a longshot question) If I manage to change the CSC will the phone be unlocked?
To try about CSC's, I have flashed the Singapore XSP but it have the XTC from Philippines by default. May be a Samsung error.
If You flash this Rom by Odin3 v3.09 You stay whit Your XTC, not need change CSC. And the flag continue 0x0.
When we say phone locked or unlocked is only about Sim card from Your carrier. You can't use the Sim from another carrier. Like my Note3 is locked to TMN. But I and You can flash what we want, Rom's, Bootloaders, Modem,s, CSC's, etc.
Make Full wipe data + cache on recovery. If You not have one customer recovery (that trip the flag to 0x1) You make this whit stock recovery, but in this case Your internal Sdcard must be wiped also. Save it to External or to Pc before.

Singapore XSP (but XTC by default) => XXUENB4_ OLBENA3_XXUENB1
