Do you want to change the stock Android OS that powers your Asus Zenfone Max? If you do want to try something new and better and if you want to keep your smartphone updated all the time, then now it will be a good idea to flash a custom ROM firmware. And in that respect, today we will discuss about the Android 8.0 Oreo based Lineage OS 15 software and how to install this particular unofficial update on your own Asus Zenfone Max.
Lineage OS 15 is one of the best custom ROMs that can be used on your Asus Zenfone Max. The firmware is powered by Android 8.0 Oreo and is currently developed and offered by those of xda-developers (we must thank them for this new update opportunity). Of course, since we are not talking about an official roll out, the Lineage OS firmware is still under development stage which means you can still find minor issues from time to time. However, according to the users who have already tested this OS, everything is running smoothly enough. Basically, you can successfully use this OS on a daily basis.
As you can tell, you are not going to use an official Android OS but an unofficial port of the default Android 8.0 Oreo system. This update is not offered by Asus and should be installed on your own risk – completing an unofficial update process will void the warranty of your smartphone. That’s happening when you initiate a process that’s not supported by your OEM; however the warranty can be restored if you choose to reinstall the stock Android software.
There are a few conditions that must be fullfiled first as otherwise you won’t be able to use the Lineage OS 15 platform. In that respect, before starting to apply the steps from below you will first have to complete two additional operations:
- You need to root your Asus Zenfone Max – the root process will unlock the system of your phone so that the new update can access and modify built-in settings, features and apps.
- You have to install a custom recovery image on your device – the custom recovery platform will be used on the actual flashing process so completing this guide isn’t possible without replacing the stock recovery image. Hint: I recommend you to use the latest version of TWRP recovery.
A backup is more than recommended. As you will notice a hard reset will be required which means that everything must be wiped out. You cannot use a custom ROM without erasing the data which is not there by default. In a few words, you can lose important files – the hard reset will wipe everything that wasn’t there from day one. You can avoid such situations by making a general backup. A backup can be done without hassle in several ways; for example you can sync personal files with your Google account or you can use different cloud storage services. Anyway, the general idea is to secure your texts, images, videos, audio files, market apps, internet settings, call logs, contacts, the EFS folder, IMEI / NVRAM data and who knows what else.
A good idea is to save the current Android OS that runs on your Asus Zenfone Max too. In that way you can anytime choose to go back to stock if the Android 8.0 Oreo powered Lineage OS 15 will not run as you previously expected. I’m talking about completing a Nandroid backup, a process that can be successfully performed through the recently installed custom recovery image.
And, finally you need to prepare a few general stuffs as explained during the following list of tasks:
- A manual update operation, like this one, can be applied if a computer can be used.
- Your Asus Zenfone Max and your phone’s official USB cable must be near you too.
- Of course, you will have to connect your phone with your computer at some point – and that’s why the USB Debugging field should be checked first.
- USB Debugging can be found by accessing ‘menu – > settings – > developer options’.
- Note: if you cannot find Developer Options, first go to About Phone and tap repeatedly on Built Number – after 7 or 10 taps you will get the ‘you are a developer’ prompt.
- Charge your Zenfone Max before installing the Lineage OS 15 ROM. This is not optional as if your smartphone gets turned off while you try to update to Android 8.0 Oreo, the Android core system can get soft bricked.
- The general recommendation is to plug in the charger if the power left is currently lower than 50%; however I recommend you to charge your phone even if the power currently shows more than 70% power.
You need to know that the steps from below, and the actual Lineage OS 15 package that’s offered in this tutorial, are compatible only with the Asus Zenfone Max with model number Z010D. So, try not to mess things up.
How to Install Lineage OS 15 on Asus Zenfone Max and Update to Android 8.0 Oreo
- Begin by downloading the required files on your computer: the Lineage OS 15 custom ROM from this page and compatible Google apps from here.
- Note: Google apps are not included by default so this package must be flashed separately on your Asus Zefone Max.
- Now, make the wipe on your phone – first, power off your device and then reach recovery mode.
- From recovery you have to select three options as followed: “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
- When done, return to Android mode.
- Use your phone’s USB cable and connect your Max with your computer.
- Select the downloaded files from your computer, right-click on them and choose copy. Then, paste the files on your smartphone.
- You can remove the USB cable now.
- On your Asus Zenfone Max access the recovery mode menu again.
- This time tap on Install or choose ‘install zip from SD card’ followed by ‘choose zip from SD card’, depending on the custom recovery image you use.
- Load the Android 8.0 Oreo ROM and follow on-screen prompts for installing the Lineage OS 15 software.
- Of course, don’t forget to install the Google apps package too.
- In the end, reboot your device into Android mode.
- That should be all.
