Android fans have been shocked to discover that Asus'tablet packs a locked and encrypted bootloader, making it nigh-on impossible to modify the tablet to run customised software.
The lock severely limits the amount of tinkering Prime owners will be able to indulge in, and was spotted by a member of the XDA Developers forum.
"This makes it impossible to flash ROMs and kernels which can really unlock the device's full potential," the post reads. "i.e. overclocking, flashing Linux distros, customising, undervolting, potentials of Windows 8 etc."
While that kind of fiddling will be beyond the cares of many tablet shoppers, the ability to mess around with your gadgetry is one of Android's major selling points, especially for ambitious geeks who love to customise their tablets and smart phones.
While Android is traditionally wide-open, Apple is infamous for the control it exerts over its products, making it tricky for anyone who wants to go off-piste when it comes to what your tech can do.
Last yearwhen it came to locking the bootloader on its mobiles, following a flood of complaints from fans. Asus may perform a similar u-turn, or it may choose to stick to its guns. We've asked Asus for comment, and we'll let you know when we hear more.
