How To Root LG G2 F320S (Korean Version)

If you are new to Android and have not heard about rooting, please read this link for information about it.

Rooting your Android device can be a scary process as the information found on the Internet is not always update to date, and the information contains inside does not always pinpoint to the condition of the device on your hand e.g. the firmware version of you phone is later than what the guides written, making your wondering if the guide still works.

 

Today I need to root my LG G2 F320S phone, with LG software (firmware) version F320S21u, Android version 4.4.2, build number KOT49I.F320S21u. This information can be found in menu > System settings > General > About phone >Software Information.

My phone has never be rooted, is running stock firmware.

 

Step 1: I need to root my phone. I use towelroot. Click the lambda sign to download the tr.pk package.

Step 2: Copy the tr.apk to my LG G2’s internal memory.

Step 3: Follow the instruction here for installing towelroot. Some of the key point is to allow the phone to install third-party application from unknown sources, i.e. the tr.apk file I have just downloaded.

Step 4: According to the instruction, I should have successfully rooted my device. I need to check to make sure my phone is rooted, so I install root checker and check. The application tells me my device is successfully rooted.

Step 5: From this web page, I know that since my phone is rooted, it means any application can do privileged actions without my knowledge! So I need to install SuperSU, which will prompt me when an application wants to access privileged actions (e.g. do something which may potentially danagerous). So I install SuperSU.

Step 6: When I installed SuperSU, it asks me how to update the SuperSU binary. I choose Normal as I don’t have any TWRP nor CWM. However, it says failed. I don’t know what to do.

One of the reason I root my phone is that in Android 4.4 (code name KitKat), there is a new change on the SD card support which you can read from here. Simply put, I can’t delete photos stored on the SD card using third-party applications, I can only use the built-in Gallery app to do. However that built-in application’s feature is average. So I need to break this limitation.

Step 7: I install SDFix: KitKat Writable MicroSD, and run it on my phone. I follow the on screen instructions to perform the operation to break the limitation. Remember to reboot the phone to make the changes in effect! Later I use the QuickPic application to delete photos stored on the SD card… and now it works!

 

It is pretty much fulfilled my purpose on rooting my LG G2… able to remove the limitation of SD card introduced by Android 4.4! However, I want to see what can I do after rooting it.

I google for “things to do after rooting android”, lots of articles come up. Like this one.

 

Remove Pre-installed System Application (Bloatware)

Step 1: Install System app remover (ROOT).

Step 2: Run the application to remove unnecessary application, which are mainly Korean application and unnecessary ones. Don’t worry! You can restore them from the recycle bin in System app remover if anything goes wrong.

Here is the list of application I removed:

  • AhnLab V3 Mobile 2.0
  • App Guide
  • Call SVC Center
  • Cyworld
  • hoppin
  • Life Square
  • Life Square Log Manager
  • MelOn
  • Mobile T world
  • Mobile T-money
  • Nate
  • NateOn
  • paypin
  • Remote Care
  • RemoteCall Service
  • Smart Bill
  • Smart Touch
  • T cloud
  • T map
  • T membership
  • T store
  • T store Agent
  • T store ARM
  • T store Downloader
  • T XXX (korean characters)

  1. I have the same LG G2 F320s from Korea with little different version of software F320S21r.

    I am using this phone in india with no problems for calling but I am not able to use it for 2G or 3G on it. My carrier in india says you should be able to select the Network Mode as WCDMA which doesnt appear in my phone. It only shows 3G only and LTE Preferrred. I tried changing the apn setting mannualy but it didnt help.

    I even tried with admin menu 5457*#320*# to select the WCDMA band but it doesnt help to enable 2G/3G data on my phone.

    If you have any idea how I can achieve this please help.
