While BlackBerry OS 10 is no longer officially supported by its parent company (now OnwardMobility is defunct, and BlackBerry Ltd. has shifted focus), thousands of users still rely on the Q20 for its unrivaled keyboard productivity and secure communication.

The restoration process on a Q20 is binary and efficient. It does not offer the granular options of Android "custom ROMs."
Crucial Note: There is no "root" access for the end-user within these files. The OS is cryptographically signed by BlackBerry. If the signature is broken, the device will refuse to boot (Security Exception Error).
