To understand the firmware, one must first respect the silicon. The RK3228A is a quad-core ARM Cortex-A7 processor paired with a Mali-450 MP2 GPU. By modern standards, this is the definition of entry-level. It lacks the raw power for high-end gaming or heavy multitasking. The "top" firmware for this device is not the one that adds the most features—it is the one that strips away the bloat to make the OS fit within the tight constraints of the RAM and storage.
