Previously (as in, before today), your warranty on your Motorola device would be voided if you requested the Bootloader to be unlocked. It was an evil, but perhaps a necessary one.
But today, it seems that change is in the air. If you request an unlock bootloader code for your Moto device you can keep your warranty. Not only that, but Moto will be posting the return-to-factory software images. Awesome, right?
This news serves as even more proof that Motorola has become more and more “Google-fied” since it was purchased by the search giant.
Moto will also be reinstating all warranties to Developer edition devices that were purchased from 2012-2013.
Remember, this information is only for Developer edition devices, and it’s definitely not expected that they’ll do the same for other devices. Still, great news.
