Install Official Android 8.0 Oreo based Oxygen OS 5.0 Firmware on OnePlus 3

OnePlus officially released the new Oxygen OS 5.0 OTA for the OnePlus 3 and OnePlus 3T. Thus, your device can be now officially updated to Android 8.0 Oreo. That’s a great thing especially since there are still important devices that are running on Nougat and not on the latest Android build – and we can only mention the LG V30 and Galaxy Note 8 in this respect. So, if you didn’t receive your OTA until now but want to flash the Oxygen OS 5.0 ROM manually then use this tutorial – below we will explain the update operation that’s compatible with the OnePlus 3.

The Oxygen OS 5.0 represents the official roll out released by OnePlus. So, we aren’t discussing about the beta build or the beta program but the actual OTA launch. Therefore, this is the fully stable Android 8.0 Oreo ROM that can ensure a great experience as you will be enjoying all the new features, apps and capabilities introduced by Google and optimized and customized by OnePlus.

The OTA is being pushed out gradually and can be received in limited markets only – at least for now. So, not all the OnePlus 3 users will receive the notification at the same time, not to mention that on your smartphone the stock Android OS must be already running as otherwise you won’t be able to receive and apply the OTA build – the same is happening if root access was previously achieved. That’s why, using a manual update process might become a pretty good idea.

Of course, manually installing the Android 8.0 Oreo based Oxygen OS 5.0 ROM is an official operation supported by OnePlus and by Google. Thus, you won’t lose your OnePlus 3 warranty while completing the steps from below. Additionally, all the steps described in this guide can be applied without problems and without using third-party apps or other risky programs. Bottom line, your smartphone will be in safe hands all the time.

Since you are applying an official Android update, your data should remain secured all the time. However, a backup is still recommended as in rare situations everything that’s saved on your phone might get corrupted during the installation operation. So, try to avoid any possible unpleasant situations and secure everything that wasn’t there from day one: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, the EFS folder, IMEI / NVRAM data and so on. On the OnePlus 3 you can complete the data easily by syncing your files with your Google Account, by using cloud storage platforms pre-loaded on your device or by downloading dedicated backup and restore apps from Google Play.

If a custom recovery image is running on your handset, you can also make a Nandroid backup. The Nandroid backup process can help you save essential Android system files. Thus, if after flashing the Oreo firmware you can choose to go back to stock by flashing the Nandroid backup package.

Perfect. Now, below you can use two update solutions. Both will show you how to install the Android 8.0 Oreo based Oxygen OS 5.0 official firmware on the OnePlus 3 – don’t use the software offered below on a different smartphone as you will risk in soft bricking its Android OS.

On your phone enable Developer Options – go to About Phone and tap repeatedly on Built Number. After tapping for 7 or 10 times on Built Number you should receive the ‘you are a developer’ message. Afterwards, access Developer Options (within ‘menu – > settings’) and check the USB Debugging field.

Verify the power that’s left on your OnePlus 3. It’s important to ensure more than 50% power as otherwise your device might get turned off in the middle of the update operation – in that particular situation you can end up in experiencing different software related problems on your smartphone. So, plug in the charger first if that’s required.
