Insanekiwi: Thank you very much for your instruction! Do I need to wipe the whole phone to be able to do it? I currently have AirWatch for work - and although I can get it installed easily, it's a pain.
Yes, you do. The full wipe is necessary to apply the local CSC (Regional customisation files) which are only loaded on a fresh boot after a reset. You can flash local software without wiping, but it won't apply the CSC and therefore will not be able to receive OTA updates.
