The normal I30 and the N version is different. All versions of make third party app (like lot of videos on youtube etc.) not work with the N version! The N version have a very hard protection in it. Somehow, it locked. With the last update (2019 summer) the application access blocked too. From the backup file, too can't reach anything to access to the system. Maybe some very good programmer maybe can do something, but i think, it's need a HW point on the prcessor to can be upload a software to get in (but that don't have the N applications) If somehow can be download the N apps, from the Android it's a good way to hack an FW to upload third party apps. And all of the settings, can't be enabled in the engineer menu. The settings are not saved/or can't be enabled.
