How to Install Lineage OS 19.1 on OnePlus 9RT 5G

As the title suggests, here we’ve shared the requirements and steps to flash the LineageOS 19.1 on the OnePlus 9RT 5G variant.

Before heading over to the guide, make sure to follow all the requirements below.

Pre-Requisites

Before we begin with this procedure, I would strongly recommend you create a backup of your device storage and all your files stored on your device. Moreover, it is advised to follow the steps mentioned in this post very carefully to avoid permanent damage or to brick your device.

Charge Your Phone

It’s highly recommended to charge your handset before unlocking the bootloader to avoid your device from shutting down occasionally while going through the process. Keep at least 50% of charge or higher for a smooth operation.

Download ADB and Fastboot Binaries

Using the ADB and Fastboot command (platform-tools), you’ll be able to boot your Android device into the bootloader mode (download mode), which will be easy for you to proceed with further steps. ADB (Android Debug Bridge) creates a connection or bridge between the device and computer to sideload files.

Whereas Fastboot is a more advanced command utility tool for Android devices that works with computers. You can download ADB and Fastboot Binaries (Platform-Tools).

Download OnePlus USB Drivers

A USB Driver is a set of files that basically allows you to create a successful and strong connection between a mobile device with a computer properly using a USB data cable. It’ll be useful to transfer files between the connected devices, flash files on the handset, and more.

It’s also worth mentioning that not only mobile devices but also other external devices can use and run USB Drivers on a Windows computer. Such as a mouse, keyboard, printer, external hard drives, speakers, USB flash drives, etc. You can grab OnePlus USB Drivers here.

Unlock Bootloader Your Phone:
