Asus Released Unlock Bootloader Tool for Transformer Prime as promised. Asus has made the unlock utility available on their website for download immediately, the link to which is in the source below, but it doesn’t come without warning. As with any attempt to alter the software or hardware, even the official method will render your warranty useless and may limit the level of support ASUS will be willing to provide. After unlocking the bootloader of your tablet, you will be able to flash custom firmwares on the device.
