[root] RegionLock Away

Sammy, in their never-ending quest to make sure they've pissed off every single one of their customers at least once, have decided to region lock their latest model devices. This means for example that you cannot use a European device with an American, Middle Eastern, Asian, ... , SIM card. You'd still be able to use the European SIM all over the world, but you would not be able to use a local SIM card while travelling outside of Europe - which would of course be much cheaper.
Sammy claims you can use any SIM card in the world after you've 'activated' with a SIM card from the region the device is from (in our example, Europe), but this has been proven by various (angry) Note 3 owners to not actually be the case.
The region lock is implemented in the form of a network blacklist. Beware that this is not exactly the same thing as a SIM lock, even though they are somewhat related. This blacklist blocks a number of whole countries and carriers, while a SIM lock whitelists one specific carrier. This app clears the network blacklist (region lock), but it may or may not remove the SIM lock, if present. Some have reported it works for them (for example: T-Mobile US Note3 on AT&T network: http://forum.xda-developers.com/showthread.php?t=2471742 ), but this should be considered a side-effect.
While removing the region lock does not necessarily affect the SIM lock, various users have reported that inputting a proper SIM unlock code does remove the region lock as well. You can purchase SIM unlock codes at various places on the internet for 20 bucks or so. A benefit of using such a code is that you do not need to root your device or use this app. If you are not rooting your device already for other reasons, I would personally not root it to just region unlock, and buy an unlock code instead.

Right now, this has only been tested on Note 3's, and found working. Rumor has it Sammy will be bringing the region lock to a lot of devices, even backporting it to devices sold in the past (aren't there laws against this?). There's no way for me to know at this time if this specific method will keep working on the Note 3, or if it will work at all on other devices. Maybe the app will need updating, maybe Sammy will block this hack altogether, etc. Only time will tell.
In theory this hack can be done without rooting or voiding warranty with some device flashing and app modding, but I'm not currently working on that because it would be highly model-specific and I'm a root user anyway.
It is not currently known exactly when the network blacklist is updated. Beware that for example updating your firmware may cause the region lock to reactivate.
Why is this paid ?
You're pretty much just buying me (half) a beer. If you do not want or are not able to pay, you can get this app for free at XDA: http://forum.xda-developers.com/showthread.php?t=2470551 . Region unlocking only takes about a minute, so if it doesn't work for you, you should also have more than enough time to refund the app as well.
- Added option to relock using backed up files
- Support for multiCSC ROMs - if it didn't work before, try again now!
