Are you eagerly waiting for the Android 8.0 Oreo official update for your Asus Zenfone 3? Well, even though the official OTA is not yet available (it will most likely be rolled out during the following weeks), you can install the beta build of the stock firmware on your own device. Successfully compiled by OreoBooyah, the Android 8.0 Oreo beta for Asus Zenfone 3 can be now downloaded and installed without problems, so let’s resume the actual flashing operation.

You will be flashing the official Android 8.0 Oreo software and not a custom ROM firmware. So, from this perspective you have nothing to worry about. Shortly, you won’t have to use third-party programs for completing this guide and you won’t risk in damaging anything. Moreover, the update operation is intuitive and can be easily completed even by a newbie. Additionally, the warranty of your smartphone will remain intact – the warranty gets void only when you use an unofficial port of the stock Android system.

Now, it should also be clear for you that the beta build of Android 8.0 Oreo is currently available. So, there might be things that won’t work as expected and which will be addressed by the official roll out. However, these will be only minor problems as you will be able to enjoy a stable and a smooth Android experience on your Asus Zenfone 3.

Since we are discussing about an official Android OS, the update operation can be completed by using the stock recovery image. Thus, root access isn’t required – keep in mind that if a rooted system is ensured you won’t be able to receive future OTAs and the only way in which an official firmware can be applied is by using a manual update procedure.

Before updating your Asus Zenfone 3 to Android 8.0 Oreo (beta) you should make a backup. It’s unlikely to lose something while the flashing operation is initiated but, in rare situations, some files might get corrupted or a wipe might erase everything that wasn’t there from day one. So, be precautious and secure the important files that might be still required afterwards. A general backup can be completed within minutes – you can save your data by using built-in cloud storage platforms which are already running on your phone, or you can just sync different files with your Google Account (of course, on Google Play you can find similar other backup and restore tools that can be anytime used on your Zenfone 3).

Now, for the update operation that’s described below you will need to use a computer. There you will save the Android 8.0 Oreo firmware package. Your Asus Zenfone 3 and its USB cable are also required. On your phone Developer Options must be enabled and the USB Debugging field must be checked – for enabling Developer Options tap repeatedly on Built Number (from About phone – just tap on that field until you notice the ‘you are a developer’ prompt) and then go to Menu – Settings – Developer Options for checking the USB Debugging feature.

Don’t forget to charge your Zenfone 3 before starting the update operation. The charging aspect is quite sensible especially when update procedures are involved. You see, the Android core system can get damaged if your smartphone get switched off right in the middle of the Android Oreo flashing procedure. So, as a precaution measure you should charge your handset if its power is currently lower than 50%.

One last thing: the beta release of Android 8.0 Oreo and this tutorial are compatible only with the Asus Zenfone 3 with model number ZE552KL. So, try not to mess things up.
