CyanogenMod was formerly the most popular custom ROM for Android devices. Unfortunately, a short-lived effort at making the ROM the basis of a business-to-business software company sank the entire CyanogenMod team and its former assets, including the name and community servers. But all isn’t lost: many of the original developers have jumped into the new LineageOS project—a direct follow-up to CyanogenMod. While the extensive device support isn’t quite what it used to be, Lineage is still the first stop for up-to-date community ROMs for many users.
