In theory, a Snapdragon 660 can run Android 12 and 13 without breaking a sweat. The limitation is not hardware; it is business. When BlackBerry Mobile (TCL) shut down the software division, the source code for the , the Privacy Shade , and the physical keyboard drivers became orphaned.
Officially, the BlackBerry KEY2 (codenamed “Athena”) never received an update to Android 9, let alone Android 10, 11, 12, or 13. It is stuck in 2018. Security patches ceased years ago.

Let’s dig into the gritty, technical reality of de-Googling (or re-ROMing) the last of the BlackBerry titans. Before we discuss custom firmware, we must understand the hardware. The KEY2 runs on the Qualcomm Snapdragon 660 . This is a reasonably well-documented chipset used in devices like the Xiaomi Mi A2 and the Moto Z3 Play.
Because the keyboard is a non-standard input method (a physical mover, not a touch layer), Qualcomm’s generic Android build does not support it. This is the primary hurdle for custom ROM developers. Let’s be blunt: This is not the OnePlus or Pixel community. You will not find a massive library of LineageOS 21 or Paranoid Android builds for the KEY2. The PKB is a niche within a niche.
In the annals of smartphone history, 2018’s BlackBerry KEY2 occupies a strange, mythical space. It was the last true BlackBerry—the final device designed by the Canadian giant before TCL’s license expired, ceding the market to a sea of glass slabs. For physical keyboard (PKB) enthusiasts, the KEY2 remains the holy grail. It offers a tactile, typing-first experience that modern touchscreens simply cannot replicate.
