Try putting a case on your Moto G, some cases will reduce or completely prevent the rattle.
You could open up the back cover and put a small piece of paper or tape in the space between the buttons and the back cover. This should prevent any excessive rattling.
I think u r missing the point,he is talking about the boot screen message which one gets when he unlock phones boot-loader ( which says your phone boot is unlocked now and you are now out of warranty )
I don't think, there is a way back as far i remember Motorola uses software based hard fuses for this and once its blown up there is no way to undo it, i might be wrong but i am sure i read it when i was researching about this phone before buying it.
