OnePlus 2 Lineage OS ROM
Update OnePlus 2 to Android 7.1.1 Nougat with Lineage OS ROM

OnePlus users are in for a treat as the next-gen CyanogenMod ROM aka Lineage OS is now supported on 50 devices including the OnePlus 2. Although the OnePlus 2 isn't officially supported by Lineage, you can still install this Android 7.1.1 Nougat based ROM on your handset, using our step-by-step guide.

Those who cannot wait for the official release may go ahead and install this unofficial port of Lineage OS, with due credit to the industrious XDA Developers for sharing this ROM.

The ROM is reportedly lightweight and slick, despite being an unofficial release. It does not include any bloatware or unwanted background programs. So, you can go ahead and customise, optimise, or personalise your handset to suit your individual taste.

You must back up your important data and settings as this procedure requires you to wipe data on the phone, besides formatting it. IBTimes SG reminds readers that it will not be held responsible for any damage to device during or after the installation of Resurrection Remix ROM. Users are advised to proceed at their own risk.

Prerequisites

  • The download files and instructions provided in this tutorial are meant for the OnePlus 2 model only. Do not attempt installing this ROM on any other variant as it could hard brick or permanently damage your device.
  • Ensure your phone is rooted with custom recovery installed.
  • Perform a Dalvik Cache wipe via Recovery Mode, if you encounter any boot loop issues after flashing the new ROM.
