Revert back to stock OS in OnePlus
This guide shows how to restore the stock Oxygen OS from any custom ROM in OnePlus 7 and latest OnePlus devices. This may work in 7 and below version of devices. But this worked 100% in my 7T device and this how I reverted back my device.
Important: Please read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps. Also take the backup of your data.
Preparation
Before we proceed, let's get all the required files downloaded.
Hope that adb and fastboot is already installed. If it is not installed, follow this guide to install it in your computer.
Let's create a folder named "android" in C: drive and move the downloaded files in this folder.
Now extract the payload-dumper-go zip file and move the payload-dumper-go.exe into the android folder, where the Oxygen OS zip file is available.
Now open the cmd/powershell and change the directory to c:/android
Use the payload-dumper to extract the image files from Oxygen OS. Run the command below.
PS C:/android> .\payload-dumper-go.exe .\OnePlusXXXX_...._XXXX.zip
Change the OnePlusXXXX\_....\_XXXX.zip to match your Oxygen OS zip file name.
After the extracting process is done. We could find a new folder extracted_XXXXXXXX_XXXXX.
Now change the command line to newly created folder.
PS C:/android> cd extracted_XXXXXXXX_XXXXX
Change the directory name extracted_XXXXXXXX_XXXXX with your matching name.
Flashing
With the device powered off, hold Volume Up + Volume Down + Power
Once the device is in fastboot mode, verify your PC finds it by typing
