It shouldn’t really come as a big shock that we here at Android Junkies just adore the LG G4. From its classy hardware to its near stock firmware, it is truly one of the best flagships produced from the Korean OEM. That being said, we won’t really blame you if you are simply tired of the stock ROM on the phone and want to install something new and exciting on it instead. This is where flashing a custom ROM comes in. So, if you have an international variant (h815) of the phone and want to install a custom ROM on it, simply follow our guide below that will teach you how to install a Custom ROM on LG G4.

Disclaimer: We take no responsibility for any damages done to your device either during or after the process, please proceed at your own risk.

Prerequisites: You will be required to have

Guide:

  • Download the appropriate ROM for your device. For this example we have chosen CyanogenMod 13 which you can download from here
  • Download the appropriate GApps package from here (Choose arm64 and Android 6.0)
  • Place both downloaded files (without extracting) on the external storage of the phone
  • Boot into your device’s custom recovery by using the command: “adb reboot bootloader” by opening a CMD window the folder containing adb binaries after connecting the device to the computer or by using the hardware keys.
  • Once in TWRP, we recommend that you create a Nandroid backup of your current ROM if you haven’t by tapping BackUp & Restore
  • Now, tap Wipe and do a cache and dalvik cache wipe
  • Tap Install and install the CM13 ROM from your SD card.
  • Once done, tap reboot system! Do NOT flash GApps directly yet!
  • After the first boot is done, boot back into TWRP and flash GApps just like you flashed the custom ROM

That is it, you will now have a custom ROM on LG G4 which will be running on Android Marshmallow.
