Disclaimer: Follow the guide at your own risk. We will not be responsible for any damage that occurs. The guide is intended for technically talented users only.

1. Download latest build of unofficial LineageOS 15 for OnePlus X (onyx) from here and save it on your phone’s internal storage. Also download Android 8.0 Oreo compatible Gapps zip file from here and save it on your phone.

2. Boot you phone into TWRP recovery (with the device powered down, hold the Volume Down and Power buttons).

3. In TWRP recovery, select ‘Wipe’ and perform a factory reset, wipe data and the Dalvik cache. Do not use the ‘format data’ option, as it will format the internal storage and the ROM you just saved.

4. Now, in TWRP tap ‘Install’, navigate and select the ROM zip file. Confirm the action by swiping the arrow to the left. Repeat it for installing Gapps file.

5. Once installation has finished, return to the main menu, reboot your phone, setup and enjoy.

Troubleshooting: If you have come across bootloop issue (stuck in a bootloop) after installing LOS 15, reboot your OnePlus X into TWRP recovery mode, and then wipe cache partition and dalvik cache. (Source – XDA)
