Update Samsung Galaxy A5 2017 with Lineage OS 14.1 custom ROM

The Samsung Galaxy A5 2017 just received official support from Lineage OS. Thus, you can now update your smartphone with this popular and appreciated custom ROM firmware, if of course you are ready to experience something new and different from the stock Samsung UI. So, the guidelines that are explained and detailed below are going to show you how to successfully install the new official Lineage OS 14.1 custom Android update on your very own Samsung Galaxy A5 2017. Thus, check each line from this tutorial in order to decide whether to choose or skip this update opportunity.

The great thing related with this Lineage OS 14.1 build is that it offers great customization and optimization possibilities. With each tweak that you will apply you will be able to improve general performance on your Samsung Galaxy A5. And, in the end you will manage to speed things up, upgrade battery life, optimize the Android UI and obtain better results when running your favorite apps and processes.

The bad thing is that Samsung released the Android 8.0 Oreo update for the Galaxy A5 2017, so this update solution might be a step backward for you, especially if you want to use the latest Android build – unfortunately, the Lineage OS 14.1 is based on Android 7.0 Nougat OS, so that’s the real downside when it comes to this tutorial. Anyway, even though the Lineage OS is based on an older version of Android, it’s still a great software that can help you enjoy a light, stable and fast UI.

Lineage OS 14.1 is a custom ROM so the Samsung UI won’t be included in the default system. The same is applying when discussing about the usual bloatware – on this custom ROM you don’t have bloatware and you can choose what to add or what to remove depending on what you want to obtain. Moreover, this is a fully stable Android 7.0 Nougat OS that will run smoothly and without any software related issues all the time.

Of course, we are not discussing about an official firmware. The LineageOS ROM is developed by third party devs and cannot be associated with Google or with Samsung in any manner. This ROM is only based on the stock Android OS but represents a free aftermarket distribution of the same software, such a ported and modified build of default Android OS. That’s why, the warranty of your smartphone will be lost once you will start the steps from below – the Samsung KNOX flag will be tripped and it can be restored only if you choose to use Odin for reinstalling the stock / official Android firmware on your Samsung Galaxy A5 2017.

A backup is more than recommended as during the Lineage OS 14.1 flashing operation a hard reset will be completed. The hard reset will prepare your phone for the new Android system, which means that the full wipe isn’t optional. Thus, if you don’t want to lose personal files, you should now backup your Galaxy A5. And for saving your data, info, accounts and files you should use backup and restore apps from Google Play (make sure you pick only already tested platforms), or you should try to sync specific files with your own Google Account. Also, you can use Samsung’s built-in cloud storage services for completing the same process.

Additionally, I recommend you to make a Nandroid backup. In this way you will be able to save the current Android OS that powers your Samsung Galaxy A5. You can afterwards use the Nandroid backup package for going back to stock without having to follow another complex update tutorial – you should do that if the Lineage OS will not run as you expected or if you will want to test the Android 8.0 Oreo software too.

Root access is also required on your smartphone – the root operation will unlock the Android system and prepare it for the custom ROM, which of course will have to add its own set of features, apps and capabilities. Also, a custom recovery image should be installed on your handset because the actual update process can be applied only through a custom recovery environment – in that matter I recommend you to use the latest version of CWM or TWRP recovery.

A computer is needed because there you have to download the files which will be afterwards flashed on your Galaxy A5. Of course, your phone and its USB cable are also required during the installation guide.

On your handset the Developer Options must be enabled – if it’s not (this field should be displayed under Menu – > Settings) you need to go to About Phone from where you have to tap repeatedly on built Number just until the ‘you are a developer’ message appears. Finally, from Developer Options you must check the USB Debugging feature.

More than 50% power should be left on your device. If the power is lower than the already mentioned threshold your smartphone might get turned off while the update operation is running. In case of a sudden shut down your device might get bricked as different malfunctions might be caused. Thus, try to avoid such unfortunate events and charge your phone first, if that’s needed.

How to Update Samsung Galaxy A5 2017 with Lineage OS 14.1 custom ROM

  1. On your computer navigate to this page. From there download the Lineage OS 14.1 package available for your Samsung Galaxy A5 2017.
  2. Also, download compatible Google Apps from here – Google Apps aren’t included in the update system so it must be flashed separately.
  3. Place both files on desktop as you will have to transfer them in a few moments.
  4. Switch off your handset and wait a few seconds. Then, reboot recovery mode on your device – press and hold the Power, Volume Up and Home buttons together.
  5. In recovery initiate a full wipe – just select ‘wipe data factory reset’ followed by ‘wipe dalvik cache’ and by ‘wipe cache partition’.
  6. Afterwards, return to main menu of recovery and select ‘reboot system now’.
  7. Next, take the USB cable and with its help connect your smartphone with your computer.
  8. From desktop transfer the downloaded files and place them on your phone; in the end remove the USB cable as the computer is not required anymore.
  9. Access recovery mode on your Galaxy A5 again.
  10. This time, from there tap on Install and load the Lineage OS 14.1 package; finally, swipe and start the update operation. If TWRP recovery isn’t used you might have to follow instead: ‘install zip from SD card’ followed by ‘choose zip from SD card’.
  11. When done, reapply the steps from above and flash Google Apps.
  12. In the end, from main menu of recovery select ‘reboot system now’.

That last reboot will bring the Android 7.0 Nougat based Lineage OS 14.1 UI on your Samsung Galaxy A5 2017. So, all that’s left to do is to try and test this new custom ROM firmware.
