Root How to Unroot Download Mode

[sammyz]

Ok so if you have rooted or have even attempted to root your phone and then try to boot to download mode, you will notice that it will say ROOTED like this picture below:

So what do you do to get it stock and unrooted 100% ?

You flash the tot firmware with LGFlashTool (not to be confused with LG Flash Tool 2014).

Downloads
Drivers
MS323 DLL
LGFlashTool
Firmware (Right click link and press "Save As")

Instructions:

1. Download the downloads (not drivers if already installed).
2. Install LGFlashTool and make sure to read the Readme file.
3. Open LGFlashTool and click the box that says "Select Manual Mode".
4. Where you see DLL on the program click the "..." button on the opposite side of it and browse to where you downloaded the MS323 DLL file.
5. Now where it says "S/W", on the opposite side click Add and browse to the MS323 tot file you downloaded.
6. On Action Mode choose BOARD DL, Connection Mode is USB of course, now click OK.
7. Now open device manager, Expand Pots, open the properties of the LGE Mobile USB Port or anything similar to that.
8. Go to the Port Settings tab, then Advanced, change COM Port Number to 41.
9. Go back to LGFlashTool and click on the 4th button from the left side and make sure only "1" is selected from the number 1-16.
10. Now click the button on the very left, now put your phone in Download Mode.
11. After it is done flashing, you will be in a mode called MiniOS, just follow the first directions you see when you are booted to it.
12. Once you follow the directions, hold power button and select the option that says "Normal Boot". Now your phone is 100% unrooted. Boot to download mode again and you will see. If there is some weird screen you see with a big number on it, just hold the power button until it turns off then turn it back on.

Makes it so easy to use this set up. Once I had run it the first time when I screwed up again everything was already in place. Just reset the port to 41 make sure drivers were downloaded (if needed) and then bring up the LG Firmware download tool ,the dll and tot files will already be in place from the first time. Click OK start, wait for it to say ready, unplug the usb, plug it right back in and let it run just like the first time you ran it.
