Download/Install Lineage OS 18 on Sony Xperia Z5 (Android 11)

2015’s model Sony Xperia Z5 (Codenamed: sumire) came with Android 5.1.1 Lollipop version out of the box and upgraded to Android 7.1.1 Nougat. But it’s been around 5 years and the official update support is discontinued for this particular model from Sony. So, if in case, you’re still using the Sony Xperia Z5 handset then you should check out how to download and install the Lineage OS 18 on Sony Xperia Z5 based on Android 11.

Due to the customizations of the open-source Android OS, most Android users prefer to customize their handsets either via flashing a custom firmware or installing a custom recovery, or even installing root access. By installing the Custom ROM like Lineage OS, Android device users can easily install themes, icon packs, custom fonts, other visual changes, and more. While installing a custom recovery will allow users to easily install flashable zip/image files on the device, backup data, restore data, factory reset, and more. Whereas root access simply allows users to use rooted apps, uninstall preloaded apps/games (bloatware), and more.

It’s also worth mentioning that you have to unlock the device bootloader first as all the Android devices do come with a locked bootloader from its manufacturer out of the box. Once you unlocked your device bootloader, you’ll be free to customize, install custom firmware, custom modules, enable root access, and more on your Android device without any limitation. Whereas Google has also uploaded the Android 11 Source Code to AOSP so that the custom firmware developers can easily build their third-party ROM for compatible devices.

Lineage OS 18 Features

LineageOS is a free, community-built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device. LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community.

It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restores the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

How to Install Lineage OS 18 on Sony Xperia Z5 (Android 11)

The installation is pretty simple and easy. If you have installed any custom ROM before then you will have no issue flashing the ROM as the process is exactly the same. But before proceeding to the installation let me clear that this build is in the very early stage which means there will be bugs and many functions may not work properly. So, we do recommend not to flash the ROM on your primary device.

Supported Models: E6603, E6633, E6653, E6683


  • Enable USB Debugging on your Sony Xperia Z5. Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.
  • Also, enable the OEM Unlock from the Developer Options.
