At this point, custom ROMs are the only things keeping old Galaxy S2s feeling fresh and vaguely modern. If you turned to CyanogenMod as your experience of choice, you've been left stranded on version 11 running Android KitKat. Now you're in for a treat. Fresh builds of CyanogenMod 12.1 are ready for download.

These nightly builds bring Android 5.1 to the four-year-old device. That's nothing to take lightly. These nightlies may not provide the most stable experience, but at this point, that old version of TouchWiz probably isn't either.

The downloads come in at around 230MB and are meant for the international model (i9100). As always, please practice safe flashing.
