Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
Make sure the device is Unlocked and rooted before going ahead with custom ROM installation. OR Check our Unlocking Guide here: How to Unlock OnePlus 2 Bootloader and Install TWRP. After unlocking, make sure to Flash SuperSU to Root the phone.
Disclaimer: Please read the following instructions thoroughly before attempting to flash your phone. Droidphoria.com absolves itself from any responsibility should something go wrong. Please proceed with caution and at your own risk.
NOTE: Make sure your Android device is charged up to 80-85% battery level. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods, etc. — your phone might get bricked or go dead permanently. No one wants that, right?
