Update LG K10 to Android 8.0 Oreo with Lineage OS 15 ROM

Do you want to update the LG K10? Well, for now there isn’t any OTA available for your device. So, the only way in which you can update your phone is by choosing to replace the stock Android firmware with a custom ROM platform. Well, one of the best choices you can make is the latest build of Lineage OS that is based on Android 8.0 Oreo. Thus, by following the guidelines explained below you can learn how to update the LG K10 (K420DS/N, m216) to Android 8.0 Oreo via Lineage OS 15.

Lineage OS is the CyanogenMod iteration. The firmware is light and will grant a pure like experience for your LG K10. Therefore, with this ROM installed you can get rid of LG’s bloatware and other similar built-in apps and processes. Additionally, the custom ROM will bring extra features which can help you optimize performance and customize the Android core system. Bottom line, on paper, with this update flashed your LG K10 should run faster, better and everything while you can choose to change everything – for example, you can even overclock or undervolt CPU frequencies.

Now, according to the users who have already tested the Lineage OS 15 ROM, the firmware is stable enough for a daily use. It’s not developed by the Lineage team but by those of xda-developers (we must thank the devs for this new Android 8.0 Oreo update opportunity) and it’s still under development team. So, you might find some minor issues from time to time – don’t worry though as all the problems are being resolved as we speak.

In order to be 100% sure that you are not going to end up in using buggy software, you should make a Nandroid backup first. Complete this dedicated operation on your LG K10 and you will be able to save the current Android OS. Afterwards, if the Lineage OS 15 ROM will not run as expected, you can choose to flash the Nandroid backup package and go back to stock without further problems.

Installing this Android 8.0 Oreo firmware on your LG K10 can be done only if root access was already ensured on your phone. Therefore, before doing anything else root the LG LK10 – that’s how you can unlock the Android system which will be now modified, optimized and customized by the Lineage OS 15 system. After gaining root access go ahead and install a custom recovery image on your handset. The custom recovery image is the environment through which you will apply the actual update package – in that matter, I recommend you to use the latest version of CWM or TWRP recovery.

This Android 8.0 Oreo update isn’t coming from LG. As already pointed out, Lineage OS is developed by third party devs. So, applying this firmware will make you lose the warranty of your device. In that respect, the additional operations recommended above are also unofficial ones. That’s why you need to be careful while preparing your phone for the update process that will shortly follow. Note: the warranty can be restored if you choose to reinstall the stock Android OS – in that case root access will be revoked, the bootloader relocked and the stock recovery image re-flashed.

You need to charge your phone before starting the Oreo update procedure. As always, is essential to ensure enough power during manual operations. Otherwise, as expected, the Android OS will get turned off. And if that happens during an update operation, various software-related problems might be caused within the Android core system. So, if you don’t want to soft brick your LG K10, plug in the charger first – do that if the power left is currently lower than 50%.

Also, make sure that a computer can be used. On this computer you will have to save the files which will be used during the flashing process. On your smartphone you need to check the USB Debugging option – this feature is located under ‘menu – > settings – > developer options’. If Developer options isn’t there you will have to go to About Phone and start tapping repeatedly on Built Number until the ‘you are a developer’ message is displayed.

How to Update LG K10 to Android 8.0 Oreo with Lineage OS 15 custom ROM firmware

  1. From your computer run your browser and then go here; from there you can download the Lineage OS 15 firmware for your LG K10.
  2. Then, from here download Google Apps – the update package isn’t including Google Apps so it must be flashed separately.
  3. You can place both files on desktop without problems.
  4. Power off your LG K10; then wait a few seconds.
  5. Afterwards, go to recovery mode and initiate a full wipe: select ‘wipe data factory reset’ followed by ‘wipe cache partition’ and by ‘wipe dalvik cache’.
  6. Return to main menu of recovery and reboot.
  7. Use your phone’s USB cable and connect your smartphone with your computer.
  8. Copy-paste the downloaded files from desktop to your handset.
  9. Remove USB connection; the computer will no longer be required.
  10. Switch off your phone and enter recovery mode on your LG K10 once more.
  11. From recovery tap on Install and select the Lineage OS 15 package. If you are using a different recovery than TWRP recovery you might have to select instead “install zip from SD card” followed by “choose zip from SD card”.
  12. Swipe and start the update process. When that’s done, repeat the last step and install Google Apps.
  13. Return to main menu of recovery when the flashing process is completed and reboot.

That’s all you need to do. Now, your LG K10 should boot into Android 8.0 Oreo. So, go ahead and use the Lineage OS 15 ROM in order to test how everything works.
