Root European LG G5: Full Guide
Rooting a European LG G5 gives you full administrative control over the device, allowing you to remove bloatware, install custom ROMs, and use root-only apps. This guide explains what rooting means for the European LG G5 (model H850), the methods available, the risks involved, and answers common questions. You will learn the exact steps, required files, and how to avoid permanent damage.
What Does Rooting Mean for the LG G5?
Rooting is the process of gaining superuser access to the Android operating system. On the LG G5, the bootloader is normally locked, and the system partition is read-only. Rooting replaces or patches the boot image so that the kernel allows the su (switch user) command, giving you access to files and settings that are otherwise hidden. For the European H850 model, LG officially allows bootloader unlocking via its developer site, which simplifies the process compared to carrier-locked US variants.
Why Root the European LG G5 Specifically?
The European G5 (H850) is the most root-friendly version of the phone. Unlike the US variants (H820, H830, LS992, etc.) that have locked bootloaders, the H850 can be officially unlocked. This means you can install custom recovery (like TWRP) and then flash Magisk for systemless root. Rooting lets you:
- Remove pre-installed apps that you cannot uninstall normally.
- Use ad-blockers that modify the hosts file.
- Backup the entire system with Titanium Backup or similar.
- Install custom ROMs and kernels for better performance or battery life.
Prerequisites Before You Start
Before attempting to root, you must back up all important data, as the process will wipe your phone. You also need to enable Developer Options and OEM unlocking in Settings > Developer options. Charge the battery to at least 80%, and ensure you have a stable USB connection. You will need a Windows PC (or a virtual machine) to run the required tools. Download the latest LG USB drivers and the official LG bridge software to ensure proper communication.
Step-by-Step Rooting Methods
There are two main methods: using the official bootloader unlock and then flashing Magisk, or using a one-click tool like LGUP with a patched KDZ. The official method is recommended for stability.
- Unlock the bootloader: Go to LG’s developer website, register your device’s IMEI, and follow the instructions to receive an unlock code. Then, with the phone in fastboot mode, run
fastboot oem unlock [code]. - Install TWRP: Download the TWRP image for the H850 and flash it via fastboot:
fastboot flash recovery twrp.img. - Flash Magisk: Download the Magisk ZIP file, copy it to your phone’s storage, boot into TWRP, and install the ZIP. Magisk is systemless, so it does not modify the system partition, which helps pass SafetyNet.
- Reboot: After flashing, reboot the phone. You will now have a Magisk Manager app, and root access is granted to apps that request it.
Common Problems and How to Fix Them
Rooting can sometimes fail. The most frequent issues are:
- Boot loop: If the phone gets stuck on the LG logo, you usually need to reflash the stock KDZ using LGUP and start over.
- Magisk not showing: Ensure you flashed the correct version for your Android version (7.0 or 8.0).
- SafetyNet fails: If you need Google Pay or banking apps, enable MagiskHide in Magisk settings.
- Wi-Fi or Bluetooth issues: This often happens after flashing a custom kernel; reflash the stock kernel or a compatible one.
Risks and Safety Considerations
Rooting voids your warranty and can permanently damage your phone if you flash the wrong files. There is also a security risk: root access means any malicious app can have full control. Always download files from reputable sources like XDA Developers. Do not use random tutorials that ask for personal information. Also, some apps (like banking) will detect root and refuse to run, though MagiskHide can bypass that in many cases.
Frequently Asked Questions
Will rooting delete my data?
Yes, unlocking the bootloader wipes all user data. You must back up your photos, contacts, and app data before starting. After root, you can restore from a backup or cloud service.
Can I unroot my LG G5?
Yes, you can unroot by flashing the stock KDZ with LGUP, which restores the original firmware and locks the bootloader (if you choose). This will also remove TWRP and Magisk.
Does root affect OTA updates?
Yes, after rooting, you will not receive official over-the-air updates. You must manually flash new firmware or wait for custom ROM updates. Magisk can sometimes allow OTA, but it is not guaranteed.
Is it safe to root with a locked bootloader?
No, you must unlock the bootloader first. Attempting to root a locked bootloader can cause a hard brick. Only the H850 can be officially unlocked; other variants may have unofficial exploits that are risky.
What is the difference between root and a custom ROM?
Root is a modified system that gives you superuser rights, while a custom ROM is a complete replacement of the operating system. You can have root without a custom ROM, but most custom ROMs come pre-rooted.
Alternatives to Rooting
If you do not want to root, you can still debloat the phone using ADB commands to disable apps, or use a package disabler app (requires no root but needs ADB). You can also install a custom launcher and use themes without root. However, these methods are limited compared to full root access.
