NEW software!!!!!...... LGUP WILL FLASH YOUR KDZ files
Download LGUP from here http://www.filedropper.com/g4 or here https://www.dropbox.com/s/d2dw48uqh4hku8m/G4.rar?dl=0 or here http://oceanhost.eu/eps4h4pmwphu/LGUP.zip.htm thank you hyelton for this link :good:
Install LGUP_8994_DLL_Ver_0_0_3_23 first and then LGUP_Install_Ver_1_14_3
Make sure you have downloaded the required KDZ file MM or LP
Start LGUP prog on your computer "make sure your phone is plugged in"
ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.

THANK YOU FOR THIS Killerdog:good: <~~~To Modify This File You Must Have Root!!
For me it's show in LGUP as unknow device.
reboot my phone, remove battery and anything else don't work.
I install LG Bridge to test, and nothing seem to work.

After make some test and search, i find some info modified by S3V3N into his rom (cust partition) that he have modify into this file:
/cust/OPEN_COM/cust_OPEN_EU.prop
Code:
ro.lge.swversion=[COLOR="Red"]some info[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]some info[/COLOR]
change to
Code:
ro.lge.swversion=[COLOR="Red"]H81510c[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]V10c[/COLOR]

restart my phone and woow it show correctly in LGUP and i can refurbish my phone.

TO UPGRADE TO MM from LP - make sure BIN file is ticked and in the File Path point it towards the MM KDZ you have downloaded. MAKE SURE YOU HAVE CLICKED UPGRADE! This will update you from LP to MM with out wiping any of your info. Press Start. Make cup of tea and be patient

TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient

TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient

If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
YOU WILL LOSE ROOT!
There is no need to enter download mode! LGUP will do it for you.

INSTALL TWRP
Make sure you have ADB and Fastboot installed.
I always put TWRP.img in the ADB folder - so if I want to boot into TWRP with out installing it this is what I do:
make sure you open a command prompt in the ADB folder "VERY IMPORTANT" and type:
adb reboot bootloader <enter>
fastboot boot TWRP.img <whatever your TWRP image is called in your ADB folder><enter> dont forget the .img at the end
That will re-start your phone straight into TWRP - You can transfer files to and from your computer while in recovery.
If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" then press install then select images then select recovery NOT BOOT then swipe to flash. This method does not install TWRP app on your phone, all you need is a reboot app from the play store that will re-boot you into recovery.

H81520A_00.Kdz flashed (by upgrade option) succesfully. It takes 10-15 mins(longest part is "android upgrading" screen.), and i lost root access. By the way root access is not necessary for upgrade.

So since it wasn't clarified, I'll be the one to ask...

Will this work on a unit without root (which is yes according to the OP), and without a bootloader unlock, ie the Taiwan (TWN) variant of the H815.

I completely understand it's a complete wipe and root will not be retained.

    I've solved the problem.
    LGUP builtin lgup_8994.dll is old. Newer FW has different lgup8994.dll.
    Just replace the old dll with new one and rename it.
    Problem will disappear.

    ---------- Post added at 02:11 AM ---------- Previous post was at 02:10 AM ----------

    You need kdz extractor for extracting the new 8994.dll from downloaded kdz file.

    USB issues - maybe a solution for some

    For those who have been having trouble getting LGUP to see their handset. Here was my experience. None of the tips in the OP worked for me.

    LG Bridge, installed on my machine - wouldn't see handset.

    LG support tool - wouldn't see my handset.

    LGUP - yes, you guessed it wouldn't see my handset!

    I tried the 'battery pull' method... this didn't work :(

    What worked for me, was the following.

    1- Uninstall all instances of LG software on your PC. This includes any USB drivers that my have previously been installed (they will show up in your installed programs).

    2- Now install the specific USB drivers for the LG G4. plug in the usb cable, make sure you have selected MTP on the connection settings.
    Your G4 should appear as accessible drives on your machine. Then you should receive a message on your phone screen asking if you would like to install the USB drivers. Tap yes/okay. (if you don't get this message there is the option on the little 3 dot menu top right of the connection options screen on the G4)

    Now a little install dialogue will appear on your PC. Let it complete.

    3- install the LGUP DLL, then when that has finished install the LGUP app itself. Let that complete.

    4- Connect the USB cable, THEN open the LGUP app. Your device should now appear... if it does breathe a big sigh of relief.

    5- select your KDZ file and drag to the LGUP window with BIN selected... select upgrade or whatever and go and make a cup of tea.

    Hope this works for you!

    :D
