Redmi Note 9 Pro Lineage OS 18 (Download and Install)
The installation is pretty simple and easy. If you have installed any custom ROM before then you will have no issue flashing the ROM as the process is exactly the same. But before proceeding to the installation let me clear that this build is in the very early stage which means there will be bugs and many functions may not work properly. So, we do recommend not to flash the ROM on your primary device.
Pre-Requirements
- Enable USB Debugging on your Redmi Note 9 Pro. Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.
