Using a custom ROM is always a good idea as long as you choose wisely. The update must be fully stable and pre-loaded with features that cannot be used on the stock Android OS. In that way you can improve the Android functionality and you can optimize and customize the UI that runs on your phone, everything while receiving the latest capabilities and apps launched on the Android platform. Well, in that regard we are now discussing about the AOSP release which is available for the Samsung Galaxy A8 2018.

XDA Recognized Developer phhusson is ‘responsible’ for this new update opportunity that’s available for your Samsung branded device. So we must thank him for this AOSP update – we are here only to explain the flashing process that must be followed.

This version of AOSP is based on Android 9.0 Pie and was optimized and customized to boot and run without problems on the Samsung Galaxy A8 2018. The update is stable and will run on a daily basis without causing malfunctions or other software related issues. Moreover, since we’re discussing about a custom ROM, the AOSP system is bringing great tweaking opportunities for your phone – with the right customizations applied your Galaxy A8 will run faster and better while you will be able to enjoy an upgraded battery life.

This isn’t an official Android Pie update provided by Samsung. It is an unofficial release of stock Android OS and it is only based on the official firmware. As already explained, AOSP is developed by third party devs so it cannot by associated with your OEM or with Google. During the update process Samsung KNOX will be tripped, so be careful about that – don’t worry, the warranty of your phone can be restored if you choose to reinstall the stock Android software (you can easily do that by using the Odin toolkit).

You’ll have to use a rooted device if you want to resume this tutorial. Root access will unlock the Android UI that currently runs on your handset as the AOSP firmware will then access and modify the built-in features, apps and settings. Moreover, the Android 9.0 Pie based update can be afterwards installed only from a custom recovery image. Thus, before doing anything else choose to flash TWRP recovery, or any other similar custom recovery platform, on your Samsung Galaxy A8 2018.

This is going to be a manual update operation. As you can tell, you must use your phone and your computer in order to complete the steps explained below. Your phone’s USB cable must be at your disposal too because you’ll need to connect your devices at some point.

A backup should be initiated on your Galaxy A8 before you begin to set up the AOSP custom ROM. Do that because a clean install will be performed meaning that everything that wasn’t there will be erased – contacts, call logs, texts, images, videos, audio files, market apps, internet settings, EFS folder, calendar info, saved passwords, IMEI / NVRAM  data and so on. Sync important files with your Google Account, use Samsung’s own cloud storage services or just save data on external storage devices. The main idea is to protect everything that might be still required afterwards.

A Nandroid backup can also help you protect your data and the Android OS that is currently running on your Galaxy A8. Since the AOSP firmware is a custom ROM, you should save the current Android OS before testing out the new Android Pie system as in that way you can always choose to go back to stock. Well, that’s exactly what you can do if you perform a Nandroid backup before going any further.

On your device the USB Debugging option must be enabled – you can find this option displayed under Developer Options. If Developer Options isn’t listed under Settings, navigate towards About Phone and tap repeatedly, for 7 or 10 times, on Built Number until you get the ‘you are a developer’ message.

On your Galaxy A8 the power left should be higher than 50%. If different, plug in the charger before starting to install the Android 9.0 Pie based AOSP custom ROM firmware. If a sudden shut down takes place while you follow the steps from below, you can end up in soft bricking your Android devicesoftware issues can be caused within the Android core system.
