And We can NOT roll back to 5.1 via Flashtool, so bear in mind and have your own responsibility.


Note that Knock code has been removed but will return in a future update.

Requirements:
You need a rooted device which is in Android 5.1 and installed FlashFire

Steps:
1. choose the "H81520A_00.zip" in FlashFire

2. choose "wipe cache partition"

3. click the thunder icon and wait....

4. it will reboot automatically and.... Welcome to Android 6.0 Marshmallow!

in fact we have 2 devices with this art to Flash and both are fine. so 100% success.
you must not feel confuse Jason. I reported the V20A KDZ in a german Forum as it came out yesterday and everybody runs out and Flash.......with no success. But....was it my mistake? NO i think. everybody must know Flash it or not. You only share you knowing with us. It is ok Jason :D @Underworled He surly dont make a Video for you and Flash it again for it. I am sure they both have there personally Things installed and no fun to Flash again. But its Jasons choice of course

LOOK , downgrading with flashtool may cause brick

If you want back to 5.1 without issue do following:

You need a TWRP Backup of 5.1 and 10D Bootloader and 10D Modem Files

1. Go to TWRP
2. Restore Backup
3. flash Modem of 10D
4. Bootloader of 10D
5. reboot and enjoy

    I did a full wipe install.
    Now at boot I get this message:

    current version is not available for user. Can't find matched cust for NT-code mcc/mnc[FFFFFF], subset[55]

    Doesn't seem to be affecting any of the phone functions, but would be good if anyone knows how to fix it.
    Your cust partition doesn`t match the cust for this rom. Try to flash the file attached, it`s the cust from 10e. If it doesn`t help, use Windows LG Firmware Extract to extract cust.img from the latest kdz which didn`t show you such kind of notification and replace cust.img in my zip with your cust.img, than flash it.
    View attachment LGG4_cust-restore_H815_10e.zip
    How to extract:
    1. Unzip the downloaded windows LG firmware Extract.zip to some folder.
    2. Copy the kdz file there.
    3. Open the WindowsLGFirmwareExtract.exe.
    4. Click Open > select the kdz file.
    5. Check the .dz file in the list
    5. Click Extract KDZ.
    6. Once extracted, open the rezulting .dz file
    5. Check cust files in the other list.
    6. Click Extract DZ.
    7. Rename the biggest extracted cust_XXXXX.bin file to cust. img
    8. Replace the file in my zip with the cust.img you have just created (I use Total Commander for this).

    and noticed any Speed improvments in Scrolling, gaming etc?

    Yes my G4 was a bit laggy when closing apps and using yt and the lag is gone now.
    It feels a bit snappier when typing but overall nothing really noticable. Don't know much about gaming since I never played any games.

    I was hoping for a better battery life actually. Haven't noticed anything better yet, but we'll see. Better give it a few days and a few recharges to settle down.

    I do like that the silent mode is available again.

    You flash zip and add the wipe cache partition.
