is notoriously difficult to crack, recent breakthroughs have seen success on the BlackBerry KEY2 and KEY2 LE, leading to unofficial builds of (based on Android 15). Top Custom ROMs to Watch in 2026
After extensive research and community feedback, we've compiled a list of the top custom ROMs available for the BlackBerry KEYone:
Notably absent from the top tier are Android 12, 13, or 14 ROMs. While experimental builds exist (such as crDroid or unofficial LineageOS 20), they suffer from broken keyboard drivers, Bluetooth call audio issues, and random reboots. On a device with a Snapdragon 625 and 3GB of RAM, pushing beyond Android 11 creates unacceptable lag. The "top" ROM, therefore, is not the newest, but the most optimized.
The KEYone’s hardware keyboard deserved better than Android 8.1. Thanks to a handful of dedicated developers, it finally has it.
Here are some interesting options:
The most significant development for KEYone enthusiasts in 2026 is the (or KEY1 upgrade) project, which bypasses original software limitations through a hardware swap:
