My device is a moto g4 on android 6.0.1 and i want to update to android 7 and my bootloader is unlocked and nothing else, i dont have root or a custom rom just stock and an unlocked bootloader, can i still receive the update?
you should be aware that the update might re-lock your bootloader. In my case (other phone, ZTE Axon7) the bootloader was locked and not able to be unlocked after the update to Android 7. I don't know if this applies for the Moto G4, maybe someone else can say something about that.
I realize this is an older thread, but I'll chime in here since I'm using a Moto X PE. My phone had an unlocked Bootloader. I gained the update to Nougat just a few days, if not weeks, ago. My phone still has an unlocked Bootloader post-udate. So my best guess is that you should be able to get it, if you haven't already. It might also depend on your phone specifically.
