Even though the Android 8.0 Oreo is officially available only for the Pixel and Nexus branded devices, you can successfully boot the very same firmware on your Xiaomi Redmi Note 3 too. Of course, you won’t be able to flash the stock / official software, but you will test the pure-like system through a custom ROM platform. Therefore, if you are ready to flash a new Android OS on your device, you can now use the lines from below where I will show you how the new Android 8.0 Oreo AOSP ROM can be installed on the Xiaomi Redmi Note 3.
The AOSP ROM (the Android Open Source Project) for the Xiaomi Redmi Note 3 is being developed by XDA senior member ‘jhenrique09’ which means that all the credits for this tutorial must go to him. I am only detailing the update process for you in order to make everything crystal clear. Only in this way you can choose wisely what’s best for your and for your smartphone as after all the goal is to use a stable, smooth and light Android platform that can perform well regardless what apps or processes you choose to run.
Thus, right from the start you need to know that Android 8.0 Oreo AOSP for the Xiaomi Redmi Note 3 is a stable and fully functional system. Of course, the firmware is still under development stage but that doesn’t mean you will not be able to use the Oreo firmware on a daily basis. However, while running on this software you might still find some minor issues from time to time – most of these issues are related with connectivity features such as USB Tether, VoLTE or Hotspot. Overall, you are dealing with a smooth Android update so you really have nothing to worry about from this perspective.
The best is that the AOSP ROM is coming with all the latest Android 8.0 Oreo features, apps and capabilities. Therefore, this is the only way in which you can test what’s new on the Android world without having to wait for the official Android roll out, which might not even embrace your Xiaomi Redmi Note 3.
Now, this update procedure can be completed only if your Xiaomi Redmi Note 3 is rooted and installed with a custom recovery image. The root access is ensuring an unlocked system which can be further modified, optimized and customized by the new ROM while the custom recovery image will be required during the actual flashing process. Note: I recommend you to install the latest version of TWRP recovery in order to make things work from your first attempt and for avoiding further problems.
All these operations are not supported by your OEM. So, when you start to root your phone you will have to assume the following aspect: the warranty of your phone will be lost. Thus, you will be exposed as if anything bad happens to your device you won’t be able to reclaim its warranty – the only way in which you can try to restore the warranty is by going back to stock: mainly I am talking about reinstalling the official Android firmware in order to revoke root access, relock the bootloader, reinstall the stock recovery image and re-apply all the bloatware and built-in apps and features.
Good; now you also need to make a backup on your Xiaomi Redmi Note 3 as the Android 8.0 Oreo AOSP firmware can be installed only if first a hard reset is initiated and only if you clear app data cache too. Of course, if you don’t previously save everything, in the end you can lose all that’s important for you – the data that’s not there from day one will be erased. Therefore, take a few minutes and use your favorite backup and restore services in order to secure your files.
A Nandroid backup can also be a good idea. This type of backup can save the Android system that currently runs on your smartphone. So, if after testing the new Oreo ROM you will feel that something isn’t right and if you will want to go back to stock, you will be able to do so without problems, by flashing the Nandroid backup package through recovery mode.
Other pre-requisites that must be considered for the steps that will follow:
- A manual update operation can be successfully applied if a computer is at your disposal.
- Don’t worry, the computer is used only for downloading the update package.
- So, your Xiaomi Redmi Note 3 and its USB cable are also required for this process.
- On your phone the USB Debugging option must be enabled – otherwise you might have connectivity problems when trying to connect your phone with your computer.
- The USB Debugging field is located under Developer Options. These options can be enabled by tapping repeatedly on Built Number (just tap for 7 or 10 times, until the ‘you are a developer’ message is displayed).
- Your Xiaomi Redmi Note 3 can get bricked if its system gets turned off while the update operation is running. Thus, avoid unpleasant situations from taking place by charging your smartphone first – do that if the power left is lower than 50%.
- Of course, resume the steps from below if you own the Xiaomi Redmi Note 3. The Android 8.0 Oreo AOSP custom ROM file that’s provided below is working only with the already mentioned device.
How to Update Xiaomi Redmi Note 3 to Android 8.0 Orea with AOSP Custom ROM Firmware
- The firmware file must be downloaded on your computer; you can get the Oreo package from this page.
- Save the ROM file on desktop.
- Switch off your device, wait a few moments and then reboot recovery mode on your smartphone.
- From recovery make a full wipe – just select “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
- Go back to main menu of recovery and choose “reboot system now”.
- Connect your Redmi Note 3 with your computer by using the USB cable.
- Select the AOSP ROM file and copy-paste it on your smartphone.
- When done, unplug the USB cord because your computer is no longer useful for us.
- Power off your device once more as recovery mode menu must be accessed again.
- From there this time tap on Install and choose the Android 8.0 Oreo system; if you are using a different recovery mode than TWRP, you might have to choose “install zip from SD card” followed by “choose zip from SD card”.
- Swipe in order to begin the flashing process and wait a few moments while this operation is being completed.
- When done, select “reboot system now” from main menu of recovery mode.
