It has been a long time coming. The Rockchip RK3188 (Quad-core Cortex-A9) was the titan of the TV box and tablet industry years ago, but official support faded long before the Android 5.1 Lollipop era truly took off. Most users have been stuck on unstable Android 4.4 KitKat builds or plagued by the "fake" 5.1 builds circulating on lesser marketplaces. rk3188 android 51 firmware exclusive

The term "exclusive" in the context of legacy firmware usually carries two meanings. First, it implies rarity. A working, stable build of Android 5.1 for the RK3188 was not a simple download from Google; it was often a patched-together solution found only in specific forum threads, hosted on file-sharing sites like Mediafire or Mega. Second, "exclusive" can refer to the sources of these files. Often, a talented developer would create a custom ROM for a specific box (like the popular MK808 or Tronsmart models). If a user owned a different brand, that firmware might not work, leading to a proliferation of device-specific "exclusive" builds.
