READ "KNOWN ISSUES" BEFORE ASKING ANY STUPID QUESTION
I used only the files from this thread
worked perfectly (phone is more responsive and snappier with Nougat)
Sorry for taking long to reply.
I'm from France ( 4g band: B3, B7, B20, B28 )
Using a Lg g4 H815 with currently the stock V20H-EUR-XX firmware ( Previously using the V20D )
My phone had big core bootloop problem. I couldnt fix it with mm without root and locked bootloader(Singapore version) had to downgrade lollipop. Any way to stop 2 big cores with this v29a?

Unnecessary:
Installation:
We need to downgrade 6.0 to 5.1 before flash Nougat
1. Check Anti-rollback version in *#546368#*815# -> SVC Menu -> Version Info (Important!!!)
If the value is 0, fine, goto step 2
If the value is v1, v2, v3 or above, DON'T USE THIS GUIDE OR BRICK YOUR PHONE
2. Install LGUP and Driver, shutdown your phone, goto Download mode by press Vol-UP, connect to your pc
You should see Firmware Update shows up on your screen
3. Open LGUP, select REFURBISH, and choose BIN file "H81510F_00_0113.kdz", press Start button
4. When rebooted, do a simple set, and go to Setting -> Backup & reset -> Factory data reset
Reboot again, do a simple set, copy rootsystem20160214.img & eu.chainfire.flash.v6.apk & LG-H815_Official_v29A.zip to internal storage
5. Shutdown and goto Download mode again, open LG ADB pack, double ports.bat , you should see\Device\XXXXDIAG1 REG_SZ COM#
The # is a random number, remember it, we'll use that at next step
6. Open cmd and change to same folder, type"#" is the number what we just seen in ports.batCode:Send_Command.exe \\.\COM#
You should see Enter, Leave and a #, copythen press enterCode:dd if=/data/media/0/rootsystem20160214.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
Wait a while, another # will appear, pull out battert and reboot
We finally downgrade to 5.1 with root, and now we gonna flash Nougat

8. In FlashFire, click "+", click Flash ZIP or OTA, choose LG-H815_Official_v29A.zip, and don't tick anything, go next step
9. Scroll to the bottom, click FLASH, click OK, wait till the phone reboot to FlashFire mode
10. When the phone reboot again, you should now see Android is Upgrading
11. Goto Setting -> Backup & reset -> Factory data reset, do a full factory reset
12. Wait the phone earse and reboot itself
13. Open LG Backup, mount your SD Card, select Restore, and enjoy your new nougat 7.0

Hey, if I already have Android Lollipop, 5.1 (V10a-EUR-XX), can I just root it and continue from step 7? If so, is there anything else I should to for the process to work properly?
are you explaining in a little more detai....sample.....command.exe file in LGH815_ADB
When you open cmd, you need to type there the address of your command.exe . For example if your LG815_ADB main file is in your desktop first you have to get in this file then start the command.exe
The same folder where Send_Command.exe located
Google "CMD Change Directory"
Google is your friend.
Woah! you have a European G4, just unlock bootloader and flash TWRP, then flash this zip, you're done!
if you stored those files at your desktop
open cmd
cd C:\Users\YOURUSERNAME\Desktop\THEFOLDERNAME
and Send_Command.exe
Be honest, don't flash this phone, or you get brick, you don't understand about flash phone, go buy a new phone is the best way to get 7.0
thanks for reply to slhsrc26.
Prerooted H815 SEA 10b system image or I can use H815 v10F KDZ ?
Hi everyone,
Can I use the KDZ file posted by the OP to downgrade to Lollipop? My phone's the international Variant (H815), bought mine in Singapore. I'm currently on marshmallow (Software version is V20i-SEA-XX). Or do I need to download a prerooted H815 SEA 10b system image? Tried searching for that prerooted system image but I can't find any. My laptop's kind of crappy so I can't do the root injection. Thanks guys!

I need your help guys. am I doing this correctly? I've done this several times but once I reboot I cant see SuperSU,so I'm not yet rootee
Hmm.. no, you can't
Download SEA 10B KDZ + prerooted system img and follow my steps, you'll get Nougat
Sorry, I can't injection root for you, ask someone : (
Or... If you can't find any prerooted system img, you can flash TWN KDZ + prerooted system img to your phone
And that would turn your phone to TWN based, some features won't work properly, do this on your own decision : )
I'm happy that you solved this : )
You're welcome : )
