Install TWRP and Root OnePlus 5/5T on Android Pie (OxygenOS 9.0+)

If you have updated to Android Pie-based OxygenOS 9.0, then follow this tutorial on how to install TWRP recovery and root OnePlus 5/5T on Android Pie.

OnePlus devices have gained a lot of recognition this year due to its powerful hardware specs and excellent software support. Recently, the manufacturer released Android Pie update for OnePlus 5 and OnePlus 5T via OxygenOS 9.0. There’s no doubt that the devices while offering a near-AOSP experience can also be customized easily, similar to the Google Pixel lineup.

If you have updated your 2017 OnePlus flagships to OxygenOS 9.0 or above and want to root the device on Android Pie, then we have got you covered. Rooting the latest Android version requires you to use a modified version of the TWRP, as well as the latest Magisk root package.

Guide to Install TWRP Recovery and Root OnePlus 5/5T on Android Pie

Just like the previous Android version, Android Pie also brings some complications to the customization scene for the OnePlus 5 and 5T. The official TWRP doesn’t play well with Pie, lacks decryption and Project Treble support and also wouldn’t allow you to flash full OxygenOS ROM packages.

To overcome this problem, you will need to install unofficial TWRP recovery on your OnePlus 5 and OnePlus 5T that is built on the Android Pie and latest TWRP source code. You can either use blu_spark TWRP by famous kernel developer eng.stk or and Codeworkx TWRP by Recognized Developer codeworkx, respectively. Both of these unofficial TWRP recovery builds are based on Android Pie source code.

Once you have flashed either one of the stated TWRP recovery builds, you can easily root OnePlus 5 and OnePlus 5T on Android Pie using the latest version of Magisk.

Prerequisites

• Take a complete backup of all your apps and data stored on the phone, including the internal storage. We also have a detailed guide on how to back up that you might want to use.
