One of the best smartphones to be launched in 2015 is the LG G4. Beating most of its competition with major innovations in design and features. It packs Qualcomm’s 64-bit, hexa-core Snapdragon 808 SoC, which runs at a clock speed of 1.8GHz and 3GB of RAM. Along with this it has a massive 5.5 inch QHD Corning Gorilla Glass 3 display, a replaceable 3,000mAh battery, and expandable storage capable of supporting a microSD card up to 128GB in size and probably the camera is the best we’ve seen on an LG Android smartphone to date featuring a 16MP sensor capable of shooting 5312×1988 pixel photographs as well as 1080p video at 60 frames per second.
One of the very stand out feature for any Android smartphone is having the ability to add new modifications to enhance its functionality. The Android developer community is constantly expanding with the addition of new devices and the LG G4 will surely be a great addition for them. Now if you are one of the very few out there who owns this beast currently and you can’t wait to get started with rooting and modifications then keep reading.
But first, before any type of flashing and rooting can take place on your device you will need to flash a custom recovery.
A custom recovery is a third-party recovery environment. It does the same things as the stock recovery along with additional features. Custom recoveries often have the ability to create and restore device backups.
One of the most popular custom recoveries is TWRP (Team Win Recovery Project). TWRP is a touch-based recovery environment. Unlike other recovery environments including Android’s default stock recovery, which needs to be controlled with the device’s volume and power buttons, this recovery environment has a touch-based interface. TWRP even supports themes. TWRP offers ROM installation and backup features the stock recovery environment doesn’t.
The following tutorial will guide you in installing the latest edition of TWRP on your LG G4 along with root access.
First of all you will need to ensure a few things before we start flashing:
- Confirm you are using an unlocked LG G4 model no. H815
- If you haven’t unlocked the bootloader then check out our detailed guide on how to Unlock the Bootloader on the LG G4
Note: Any carrier-specific model might not work with this method. User is to perform this at their own risk.
- Ensure that you have the necessary LG USB device drivers installed (Download here).
- Check if you have at least 80-85% of battery charge. We don’t want the phone dying in the middle of the process.
- If you have done this process before on other devices then you must be familiar with adb and fastboot. Ensure that you have it installed.
