LG will soon release the official Android 8.0 Oreo OTA for the G6. But, until then, if you want to try the latest Android build right away, you can choose a different update solution. I’m talking about flashing the latest release (unofficial) LineageOS 15.0. So, yes, it’s about installing a custom ROM firmware on your LG G6. But, the result will be just great, as you will see by yourself in a few moments.
Lineage OS 15.0 for LG G6 is developed by those of xda-developers – you can access the official thread here. The software is stable enough for a daily use, so there might be still problems on this platform – only minor ones as you will be able to smoothly use all the Lineage OS features, apps and processes. Bottom line, completing this flashing operation is a good idea if you are an experienced Android user and if you want to test the stock Android 8.0 Oreo without waiting for the LG OTA release.
Therefore, this new LineageOS build is based on Android 8.0 Oreo. Well, the firmware is quite light and clean meaning that you can get a pure Android experience on the LG G6 with the help of this custom update. The ROM will run fast and you will be able to experience different tweaks that cannot be used on the stock system. Overall, your phone should offer better results when running on Lineage OS 15.0 compared with what you currently obtain.
And using a custom ROM can be done without risking anything, if you first make a Nandroid backup. That’s how you can store the current Android system files in order to get a package that can be later used on a downgrade operation – by using the Nandroid package you can choose to revert back to stock if that’s what you will decide after testing the Android 8.0 Oreo OS.
This is going to be an unofficial update operation so prepare yourself to face some negative aspects too – the main aspect is of course related with the warranty, which by the way will get void if you choose to resume the steps from below. The warranty can still be reclaimed but only if you first go back to stock – situation during which all the tweaking operations that were previously applied will be revoked.
You can install the Lineage OS 15.0 custom ROM without issues but only if you first take care of the additional operations mentioned during the following list:
- You must root your LG G6 first – an unofficial firmware can replace the stock one only if the current Android system is unlocked, process that can be completed only through root.
- Install a custom recovery image on your LG G6 – third party .zip files, such as the Lineage OS system, can be flashed on your phone only if a custom recovery image can be used.
- Hint: for making things work without any sort of issues I recommend you to choose the TWRP recovery package as your custom recovery software solution.
- Make a backup on your LG G6 because during the steps from below a hard reset will be completed – you cannot use the new ROM unless you first clear everything that’s not there from day one.
- Note: on the LG G6 you can easily apply the backup process as you can already use built-in cloud storage services, you can choose to sync your personal files with your Google Account or you can use other similar backup and restore tools from Google Play in order to secure everything else.
As you can tell, this is going to be a manual update operation. So, first you will need to download the Android 8.0 Oreo firmware – and that’s why a computer is required. A connection between your smartphone and your PC will have to be established at some point. And for being sure that ths connection will be properly set, you must first check the USB Debugging option – it’s located under “menu – > settings – > developer options”. Hint: you can enable Developer Options on LG G6 by tapping repeatedly, for 7 or 10 times, on Built Number – while tapping on this field you will get the ‘you are a developer’ message.
Problems, such as a soft brick, can be successfully avoided if you first charge your LG G6. As a general rule, before initiating any sort of manual operation, you should plug in the charger if the power that’s left is lower than 50% – otherwise the Android system might get turned off right in the middle of the implied manual operation.
This guide is working only if the LG G6 is used so try to keep it that way – you can damage your Android based device if you’re not careful enough.
How to Update LG G6 to Android 8.0 Oreo via Lineage OS 15.0 custom ROM firmware
