OnePlus recently made Android Oreo Beta build available for the OnePlus 5. This build has been made available to users via flashing. Since this is a new build, it is not available via OTA at the moment.
For users who have installed the Android Oreo Beta build on their OnePlus 5 devices, and need a way to roll back to Android Nougat, this post gives a detailed guide on how to go about it. If you wish to download the beta update, click here.
The first thing you need in order to perform this rollback is the OnePlus 5 rollback to Nougat firmware. This file is about 1.56 GB in size. You must also have Oxygen Recovery on your device if you wish to install the rollback firmware easily, and without any bugs. Oxygen Recovery comes by default on the device. However, if you installed TWRP, you should now install Oxygen Recovery. Download it here. Install it using the guide here.
After getting the above ready, follow either of the guides below to roll back to Android Nougat.
Make sure to make appropriate backups of everything you need (photos, videos, documents, music, etc.). This is because the rollback will wipe your device, and everything will be deleted.
Method 1: Using Recovery Mode
Download the Nougat rollback firmware here.
After downloading the rollback file, transfer it to your OnePlus 5. Make sure that you note its location.
Boot your device into recovery mode. This is done through the following steps:
- Switch off your OnePlus 5.
- After screen goes off, wait for 6-7 seconds, then press and hold Power + Volume down simultaneously until anything is displayed on screen.
- Use the volume buttons to bring up Recovery Mode option at the top of the screen.
- Press Power button to select the Recovery Mode option.
- Following these options, your OnePlus 5 will be booted into Recovery Mode.
Install the rollback firmware downloaded above. Click here to download it, if you have not. Install the firmware by following these instructions:
- In Recovery Mode, navigate to the ‘Install update…’ option using the volume buttons. Select the option using the Power button.
- Select the update file that you transferred to your OnePlus 5 in Step 2.
Wait while the update is installed. When done, the device will be back in Recovery Mode homescreen.
Select ‘Reboot system now’ to restart your OnePlus 5.
Method 2: Using ADB Sideload
Rename the file downloaded in Step 2 above to op5-Nougat-rollback-firmware.zip. This is to make it easy to install when you get to Step 9 below.
Enable USB debugging. Do this by following the steps below:
- On your device, go to Settings > About Phone.
- Tap ‘Build number’ seven times to enable Developer options on your phone.
- Go to Settings > Developer options.
- Tick the ‘USB debugging’ checkbox.
Connect your OnePlus 5 to PC via USB.
On PC, open the folder where you downloaded the zip file of the firmware.
Open a command window inside the folder. Do this with a ‘Shift + Right click’ on any empty space inside the folder, and select ‘Open command window here’ from the context menu.
Command window to reboot your device into recovery mode, by issuing the following command:
adb reboot recovery
If your phone asks, ‘Allow USB debugging’, select OK/Yes.
As soon as your phone is in recovery mode, navigate up and down using the volume buttons, and use the power button to select an option.
On the device, select ‘Install from USB’.
Run the following command to install the rollback firmware:
adb sideload op5-Nougat-rollback-firmware.zip
The firmware installation will now begin.
After installation, restart the device by selecting the reboot option from the Recovery’s main menu.
