Update LG G4 H818P to android 7 by LG-H815 Official v29A.

[Serb.Kosj]

Thanks for the answer, it worked very well. I successfully used CMD instead of Powershell.

Now I followed all the steps
After I copy this command from the ports file
"LGANDNETDIAG1 REG_SZ COM5" (without these marks), I got this error
"The system cannot find the path specified."
The next command I tried
"Send_Command.exe \\. \ COM5"
The error I got is
"Author : blog.lvu.kr
SPECIAL COMMAND : ENTER, LEAVE

USAGE : Send_Command.exe [PORT]"
It doesn't do anything, no type id , can't progress any further!

this is not an error ! after entering "Send_Command.exe \\. \ COM5" just TYPE : id
after that you can continue the steps in the first post

I''ve tried
Send_Command.exe \\. \ COM5 then press enter (same message as before)
Send_Command.exe \\. \ COM5 type:id
Send_Command.exe \\. \ COM5 TYPE:id
Send_Command.exe \\. \ COM5 typeid
A message "uid = (0) root gid = (0) root" is supposed to happen right? After Send command?
Looks like something is wrong Nothing is happening!

operable program or batch file.

This is all I get in CMD, no success.

How's the battery life of LG G4 running Nougat? I really hope it's better than MM. Also, I have heard that the performance is also improved. I mean the general UI navigation has become more smooth and fast response when opening apps. What is your experience regarding that?

Thanks a lot! I instead used "Refurbished" in LGUP, In no time I got Nougat. Phone feels new and snappy. No issues till now. The high contrast is just awesome in Themes. LG forever.

I have a LG G4 H818P (dual sim) but it has a broken motherboard. I was wondering if I can replace the motherboard with other motherboard versions like F500, H810, H815, VS986, VS911 or H818?

Thank you

I managed to follow steps by OP but could not root my phone.. I managed to install 5.1 kdz with LGUP from MM.

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.

I believe instructions starting from 11 are not complete, maybe spacing etc, can someone advise the correct instruction? or can I root with Super SU or other methods?

After adjusting the spaces, I managed to flash Nougat ROM but got error current version is not available for user. I assume the ROM is not for my region south east Asia. Does anyone have a quick fix?
