Asus has responded to demands for an unlocked bootloader for its its latest Transformer Prime tablet.
It turns out that DRM is the culprit – at least, that is what Asus says on its Facebook page:
Regarding the bootloader, the reason we chose to lock it is due to content providers’ requirement for DRM client devices to be as secure as possible. ASUS supports Google DRM in order to provide users with a high quality video rental experience. Also, based on our experience, users who choose to root their devices risk breaking the system completely. However, we know there is demand in the modding community to have an unlocked bootloader. Therefore, ASUS is developing an unlock tool for that community. Please do note that if you choose to unlock your device, the ASUS warranty will be void, and Google video rental will also be unavailable because the device will be no longer protected by security mechanism.
My guess is that most modders will cheerfully unlock their bootloaders and ditch the DRM. That said, I am not clear why this should void the warranty unless it is software related.
