Installing the H815 Nougat Stock [v29A] on the H818P.

5.1 Installation
1 - Download KDz from 5.1;
2 - Put the phone in download mode and open the LG UP;
3 - Load KDz into the program and start;
4 - I hope to connect, configure and depart for the next procedure.

Root process
1- Download all files;
3 - Download IMG from the V10C BRASIL system or V10D Brasil (check the version of your software), after downloading and downloading the IMG to the internal memory of the device.
4. Install the drivers (if you do not have one) and extract the LG_Root.zip to the LG Root folder;
5- On the device, enable USB Debugging in the Developer Options;
6- In the LG Root folder, right-click pressing shift and click Open Command Window here.
7- Connect the USB cable to the computer and allow debugging;
8- In the open command window type adb.exe devices, so if the device is connected the computer will inform in the window. Example: List of devices attached, LGH818P (letters and numbers), device;
9- Disconnect the USB cable and the device. With it off, press the volume more, plug into the USB port, the device will turn on Download Mode;
10- Go back to the folder, with the device already in Download Mode, double click on the Ports file, it will open another command window, copy the port number that appears in \ Device \ LGANDNETDIAG1 REG_SZ COMxx, note the xx because it is the number of the door, write down the number, then close the window that has been opened;
11- Go back to the command window that you had previously opened, in it copy and paste the command Send_Command.exe \\. \ COMxx and change the xx by the number of its port;
12- Still in the window, type id, a message will appear. Example: uid = (0) root gid = (0) root. If it does not, type again;

13- It's time for root, you should be sure now that you have copied the correct port and that the file from step 2 is in the internal memory. Enter the command
dd if=/data/media/0/system.rooted.H81510c-EU.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
and hit Enter on your keyboard. It should take about a minute, wait until # appears.
14- After you finish, type LEAVE for your device to reboot. Root is done.

Installing Nougat
1 - Right after Root download the Flash Fire, and install it;
2 - Copy to rom for internal storage, compact even;
3 - Right after pressing the "+" and select the option "Flash ZIP or OTA";
4 - Ira appears to navigate the internal memory, select the rom;
5 - Then select the "Flash" option;
6 - It will restart and soon after starting the installation;
7 - Ready, now just wait;
NOTE: In the LG logo it will take a little, something from 3 to 5 minutes.

IF YOU WANT DOWNGRADE 7.0 TO 6.0
SEE ALL HERE
http://raspberryjuntopi.com.br/2017/...o-marshmallow/
https://www.youtube.com/watch?v=9Vk1...ature=youtu.be

FILE H815 V20o Modded.kdz
you can drop from 7.0 to 6.0 and run the manual modem
The easiest way to get it manually (you need root):
Copy the IMG-file of the modem in the internal storage (do not rename it!)
on your computer, the command ADB line
Execute «adb shell» (without the quotes)
Lift the skin with the command su (again, without quotes)
Then execute the following commands:
dd if = / dev / zero of = / dev / block / platform / bootdevice / by-name / modem
dd if = / sdcard / modem_h818p_20h_gcc.img of = / dev / block / platform / bootdevice / by-name / modem
Finally, restart your phone and it should work.

NO. you lost signal.
If you try to Flash kdz file but it stops at 9% with error 0x2000 flashing fail .
Try replacing your LGUP dll with this one: LGUP_8994.dll
https://mega.nz/#!b51GGDLL!n42yqpAIa...8tsHhPkC_XDs5M

It's located in this directory:
C:\Program Files (x86)\LG Electronics\LGUP\model\8994
Or this one if you have a 32-bit windows pc:
C:\Program Files\LG Electronics\LGUP\model\8994

And then flash KDZ again

Thanks. The instructions should have indicated that I should be in Lollipop first before going through the steps.
