Recently, Cyanogenmod released CM13 (Marshmallow) for 2011 Sony Xperia devices. The custom rom shared in this article is specifically meant for Xperia Arc and Arc S (anzu). The ROM is based on Android 6.0 Marshmallow. This rom has been tested to be fully working on Xperia Arc S (LT18i) by me. So far, it runs smoothly. The only bug in this ROM is with the Bluetooth. It sometimes refuse to enable.
Since the internal storage of this device is small, a fast SDcard is required to be used as the data partition. If you wish to install this rom on your device, read and follow the three easy steps below carefully.
- Cyanogenmod 13.0 for Arc and Arc S - Download
- Recommended Gapps - Download
- Adb/Fastboot package (Important) - Download - Mirror
