Install /e/OS on a LG G5 (International) - “h850”

The instructions in this guide will assist you to install /e/OS on your h850. Please read through the instructions at least once before actually following them, so as to avoid any problems later.

It is important that you know that downgrading Smartphones on OS versions greater than the /e/OS OS version you plan to install, can cause instability or at worst brick some devices. We recommend that you check your current OS version, before attempting the installation.

It is advisable to flash your device only if you know what you are doing and are ok taking the associated risk. All /e/OS builds are provided as best effort, without any guarantee. The /e/OS project and its project members deny any and all responsibility about the consequences of using /e/OS software and or /e/OS services.

Requirements

If required take a backup of all important data from your phone on an external storage device before proceeding.
Do not take a backup on the same device as some of these actions will format the device and delete the backup.
Ensure your phone is charged more than 50%
Check that adb and fastboot are enabled on your PC. If not you can find the setup instructions here
Download all the files and images mentioned in the download section below before starting the installation
Make sure you have a working data cable to connect your device to the PC. There are cables which are only for charging and do not transfer data.
Enable USB debugging on your device. You can find the instructions here
Make sure that your model is listed in the Smartphone Selector. Check the model supported. Where available, information on the model supported should show as a pop-up when you hover the cursor on the Device name. The model number supported should be the exact same.
Boot your device with the stock OS at least once and check every functionality.

Warning: Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it will not work on /e/OS as well. Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.

Unlocking the bootloader

Tip: The steps given below only need to be run once per device.

Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or an online drive

Warning: Some vendors/manufacturers prevent the bootloader from being unlocked. Depending on where your device was acquired you may or may not be able to unlock the bootloader. To verify if your device is compatible please check the devices list.

Visit LG’s official unlocking website, where you’ll be asked to login.
Follow the instructions and get your unlock file.
Connect your device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
```
 adb reboot bootloader
```
Once the device is in fastboot mode, verify your PC finds it by typing:
```
 fastboot devices
```
Now type the following command to unlock the bootloader:
```
 fastboot flash unlock unlock.bin
```
Where unlock.bin is the bootloader unlock file you received in the email.
Wait for the bootloader unlocking process to complete. Once finished, you can check if bootloader is successfully unlocked by typing:
```
 fastboot getvar unlocked
```
Verify that the response is unlocked: yes. In that case, you can now install third-party firmware.
Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using `fastboot`

Before proceeding ensure you have downloaded the custom recovery from the link given in the Download section above
Connect your device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
```
 adb reboot bootloader
```
You can also boot into fastboot mode via a key combination:
- With the device powered off
- hold Volume Up + Power.
Once the device is in fastboot mode, verify your PC finds it by typing:
```
fastboot devices
```
Tip: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root

Tip: Some devices have buggy USB support while in bootloader mode. If fastboot hangs with no output when using commands such as fastboot getvar .. , fastboot boot …, fastboot flash … try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub
Flash a recovery image onto your device by typing
```
 fastboot flash recovery recoveryfilename.img
```
Replace the recoveryfilename with the name of the recovery image you downloaded in the previous section
Now reboot into recovery to verify the installation:
- With the device powered off
- hold Volume Down + Power until the LG logo appears, then release Power for a second and hold it again until the recovery comes up.
