So could this be used to flash ROMs onto an unrootable device? Not "unrootable", but USB debugging doesn't work on it so I can't root it but there are ROMs for it
No this is just an emulator, it doesn't do anything to a real device...
??? That's something that can't happen, maybe you are referring to the notification led
You have to reflash the firmware using fastboot, you can find the tutorial here on XDA, just make sure to don't install a KitKat firmware if you have all ready installed official lollipop, if you do you will get a hardbrick
Thanks!!! It worked on th german retail 4.4.4
