Step 7

Step 8

Step 9


First Boot: Device will reboot once at first boot, at start of setup! Upon reboot, will optimize apps and proceed to setup.

Root: It is now disabled by default on CM12. To enable it go to Settings>Developer Options>Root access and set to Apps only or Apps and ADB.

OTA : Since this is the official CM 12 nightlies they will receive continuous updates via OTA. If you want to flash via zips, visit this link. But bugs may happen so please take a backup before performing an OTA so you can roll back to the last working version without a hiccup.

Dual SIM: Dualsim variants (a5dwg, a5dug) are supported, but not fully functional. It’s not possible to make calls if you selected 2G as preferred network mode.  I would suggest you to only use one sim card with the dualsim variants.
