HTC One Max can still be updated. No, not by using OTAs or any other similar official updates, but through custom ROMs alternatives; and the best is that your One Max will run better than it currently does. That’s possible thanks to dedicated features, apps and capabilities which are there to customize and optimize the Android core system. If that sounds good, then this tutorial might be exactly what you need – during the following guidelines I will show you how to update your HTC One Max to Android 8.0 Ore with Lineage OS custom ROM.
Yes, Android 8.0 Oreo can smoothly run on your HTC One Max. The ROM is pre-loaded with the latest Oreo features along with extra capabilities which cannot be found on the stock Android system. These extra capabilities will ensure a smooth Android experience regardless of what type of apps and processes you will choose to run on your phone. And everything is possible thanks to those of xda-developers who managed to compile the Lineage OS 15 firmware on the HTC One Max.
No, the update is not yet fully stable, but it can be successfully used on a daily basis – if problems are found than we are discussing about minor issues that aren’t stressful in any manner. However the devs are working to fix all the reported bugs so a stable Linage OS 15 software will be soon ensured – until then, this Android 8.0 Oreo release will be just perfect (as already outlined, the ROM will smoothly run on your phone).
If you are still skeptic you can make a Nandroid backup on your HTC One Max before resuming the Android 8.0 Oreo update process explained below. The Nandroid backup will save the current Android OS that runs on your smartphone. Well, you can anytime choose to use the Nandroid backup for going back to stock, if for example, the Lineage OS will not run as you expected in the first place.
Since you are not going to use an official OS released by your OEM, completing this tutorial represents an unofficial operation. In conclusion, the warranty of your phone will get void – you can restore it by re-flashing the stock Android software.
You need to use a rooted HTC One Max. Unfortunately, the Lineage OS 15 ROM can be applied only on a rooted Android OS – so, an unlocked system is required because the Android 8.0 Oreo software will have to access, modify and optimize the existing firmware.
Additionally, a custom recovery image must be installed first. Without a custom recovery you cannot flash the custom ROM – through the recovery environment you will first initiate a hard reset and then complete the actual flashing process. Therefore, if you want to apply the steps from below without experiencing any sort of problems, first install the latest version of CWM or TWRP recovery on your HTC One Max.
As I already mentioned, a hard reset will be required. Because of that it’s more than recommended to backup your HTC One Max before doing anything else. If the backup isn’t performed you will lose your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data and basically everything else that wasn’t there from day one. The backup can be applied by using third party apps from Google Play, by syncing your files with your Google Account or by using any other cloud storage solution.
This is going to be a manual update procedure. So, a computer or a notebook must be used – don’t worry, on that computer you will only have to download the required files. However, on your smartphone the USB Debugging option must be checked. This feature is located at Menu - > Settings - > Developer Options. It can be possible that the Developer Options field will be missing. In that case, navigate towards About Phone and tap repeatedly (for 7 or 10 times) on Built Number – when the ‘you are a developer’ message will be displayed you will be able to access Developer Options.
It’s imperative to charge your HTC One Max before updating to Android 8.0 Oreo. The charging process should be applied if the power left on your device is currently lower than 50%. In that particular case your handset can get turned off during the Lineage OS 15 update process, situation during which your smartphone can get soft bricked – different soft related problems can cause malfunctions within the Android core system.
How to Update HTC One Max to Android 8.0 Oreo via Lineage OS 15 custom ROM
