Download/Install Lineage OS 18.1 on Sony Xperia Z4 Tablet (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.
- Enable USB Debugging on your Sony Xperia Z4 Tablet. 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.
- Make sure the bootloader on your device is unlocked and your device is rooted and you have a custom recovery installed.
- Make sure your device has more than 50% battery.
- Make sure you have taken a backup of your important data. Now proceed to install Lineage OS 18.1 ROM (Android 11) on your Sony Xperia Z4 Tablet device.
- Make sure that you have installed TWRP recovery on your Android device.
