(Q) Any way to flash a rom without needing an FTF topic

As the title states, is there a way to flash a new rom without being tied down to a PC / laptop?

Bootloader's unlocked, rooted, it's strange how with this phone we're forced to stay locked down to a PC.

Have never flashed anything from the Original Dev section on this phone yet, would that be the same method as normal rom's like monx's and IHackers?

Cheers.
