The Asus Transformer TF300T is probably one of the earliest and most refined convertible tablets that the market has seen. It came with a well built and sturdy keyboard dock that featured a trackpad mouse, a full sized USB port, and even its own battery. Its insides weren’t lacking for its time either, packing a quad core processor clocking in at 1.2 GHz. With a spec sheet like this, it was no doubt a popular device with some great development history.

Two years later, the TF300T is still going strong, receiving its own unofficial port of MultiROM thanks to the efforts of XDA Senior Member f69m. As we can all assume, MultiROM lets you easily boot multiple ROMs without having to wipe and restore ROMs. F69m does make it clear that the port is still in its early stages, hence a couple of features that you would expect to see will not work as of yet, including:

• Store secondary ROMs on external SD cards (including both the tablet and keyboard dock slots)
• Install Ubuntu Touch as a secondary ROM

Other than that, the port still retains the core functionality of running a primary Android ROM, and booting secondary ROMs from internal memory as well as an external USB drive. The MultiROM port will also need a modified version of TWRP in order to run, and this is also provided in the original post.
