Manually Update OnePlus 3T to Android 8.0 Oreo via Official Oxygen OS 5.0 OTA

OnePlus 3T can be officially updated to Android 8.0 Oreo OS. And this time we are not talking about the Oreo Beta program but about the official OTA release. Yes, if you didn’t know, the new Oxygen OS 5.0 ROM is official and available for the OnePlus 3T.

However, if the Android notification is nowhere to find, you can skip the usual OTA wait by flashing the firmware manually. And that’s exactly what we will be doing during this tutorial – describing the manual update operation that’s compatible with your OnePlus 3T.

As usually, an ‘over the air’ roll out is offered gradually or in phases. Shortly, some users will receive the update sooner than others. Also, only the devices that are already running on stock Android and which aren’t rooted can receive the Android notification. Therefore, you can receive the Android 8.0 Oreo based Oxygen OS 5.0 ROM on your OnePlus 3T only in certain conditions. Well, if you want to test the new firmware right away, you can just apply the steps from below.

This tutorial is describing and detailing two different ways in which the new OTA can be manually installed on the OnePlus 3T. Both processes are official ways in which an OTA can be flashed on your phone; thus you will keep everything safe and secured – you won’t lose your phone’s warranty (that happens only when a custom ROM is used) and you won’t have to use risky programs for completing the installation process.

The Oxygen OS 5.0 update is the fully stable Android 8.0 Oreo firmware that’s now available for the OnePlus 3T. Shortly, you can use this software on a daily basis without worrying about soft related problems such as boot loops, lags, hangs, bugs, screen freeze, battery drain or similar other issues.

A backup is recommended especially if you want to use the second update solution that’s indicated below. In that case a hard reset will be initiated, which means that the data that’s stored on your smartphone will be wiped out. Therefore, for securing your personal, data, info, accounts and files you should use your favorite backup and restore tools – sync your data with your Google Account, use built-in backup services or use cloud storage platforms available on Google Play. Additionally, if you can use a custom recovery image consider in initiating a Nandroid backup – that process will save the current Android OS that runs on your OnePlus 3T.

A computer will be required for the processes described below. There you will have to download the Android 8.0 Oreo featured Oxygen OS 5.0 firmware package. On your OnePlus 3T you have to become a Developer as afterwards you need to check the USB Debugging field: first, go to Settings – About Phone and tap repeatedly on Built Number until you receive the ‘you are a developer’ message; then, from ‘menu – > settings – > developer options’ find and check the USB Debugging field.

You should start the steps from this guide only after charging your OnePlus 3T. This is an important part of the update process because if your phone will get switched off while the Android 8.0 Oreo system is applied you can end up in soft bricking your device. And the only way to avoid such unpleasant situation will be by ensuring more than 50% power on your phone – if the power that’s left is currently lower than the already mentioned threshold, don’t hesitate and plug in the charger before doing anything else.

Don’t forget that the Oxygen OS 5.0 firmware package indicated during the following lines is compatible only with the OnePlus 3T. Don’t follow this tutorial if you are using any other Android based device as you will only manage to mess things up – for the OnePlus 3 you need to use this steo by step update guide instead.
