I've have upgrade my H818P to Nougat and now it stuck at LG logo and couldn't turn off unless I take out the battery.

And very bad case that now I couldn't put the phone into download mode.

Even when go into factory reset mode, it did nothing when I press Power button at 2nd "Yes" for confirmation of hard reset.

Is there any way to fix it or is its mainboard already dead?

This happend to me too i reflashed nougat file again and in the next flash its worked and phone started
[G4 Android Development] tphg:
You are more lucky than me that your phone could go to download mode for you to flash again. Mine could not be put into download mode, even using fastboot in Mini ADB was still unsuccessful, it always stuck at LG logo.

In nougat we cant unlock bootloader ?

---------- Post added at 08:04 AM ---------- Previous post was at 07:59 AM ----------

Bro i have successfully installed nougat on my H818P and i want to root it now so is it possible.

If yes can you say me steps for unlocking the bootloader and twrp link
[G4 Android Development] maneroman:
is there any other download link for H818p?
[G4 Android Development] JoniJnm:
To restore the old version, only works H81520p_00_0314.kdz
[G4 Android Development] anonymous1:
For anyone else with a H815 TWN variant, the H815EU v29a TOT file works if you follow the instructions others have posted on how to install (search the thread...there's even a video guide!)

Battery life doesn't seem as good, but it could be my 2 year old battery! Phone dies even when battery reporting 35% charge remaining. Will order a new battery and see how it fares.

Now, if only I could be brave enough to 'unlock' using USU, then I could have root and use a custom ROM...waiting on a list of USU compatible roms from steadfaster (he's the man).

SO...if this 'test' version of Nougat works for most people, why were LG stupid enough not to release it officially. Guess they are intent on p-ing everyone off so their mobile division goes down the pan?!

If you look at the G7 'Thin Q', then you can see they haven't learnt a thing from their mistakes.

Well, well...at least I got to see what Nougat is like on the G4 and it's not at all bad, especially if you use a new theme that you can get off the 'Play Store', don't use the useless ones from LG World.

I have been using the rom for a while and very happy from its performance, I recently had a problem but not sure if the cause is the ROM or something else. I am using OneDrive from microsoft. The personal account works perfectly fine, but if I try to use my university account (which has a 1Tb space) I can not log in. If I try an other phone that has Android 7.0 there is no problem I can log in. Can this be related to some security options? Anybody has any idea?

[G4 Android Development] whitewolf1608:
Charge the batteries fully.

Plug into the USB cable.

Check if your phone is detected for the Minimal ADB and Fastboot tool

the console by entering the following commands:

1 - adb devices

After this command, the console should respond with a sequence of symbols.

These symbols mean that you are well on your way to connecting to Minimal

adb and Fastboot.

I wish you that the sequence of characters after the above-mentioned command will show up with you.

If you do not get a String of characters and you get unauthorized.

Then try to use these two additional commands in this order:

1 - adb start-server

2 - adb kill-server

Next, issue the command adb devices to the console and write if he has a connection?

The advice above does not depend on whether you are blocked or unlocked

Bootlader. Simply restarting the connection should work.

How the smartphone worked for you or whether it worked well for you

connection with Minimal ADB and Fastboot?

Write all details.

What's your current Android?

Did you fill Super SU applications for TWRP ripping?

How you Flashed the same TWRP Recovery whether by the app or through the package

cmd - a console in Windows?

Describe me all the details and maybe

You don't need to update this way as you should be able to officially unlock the bootloader.

Once done, then you have the option of a lot more ROMs, including custom ones.

note:

after my g4 put on download mode and plug to LGup,

it said that my phone is H815... [whaaatt???]

so, if i want to downgrade, should i use the h815 v20o or h818 v20p

when i upgrade to Nougat, i use the H818p 29a TOT file.

anyway, if i want to downgrade, which file should i use... since my phone is 818P...?

EDIT:

Ok now, im succefully flash the H818P v20p 6.0 KDZ ( MM to for Back) kdz file [from 1st post]

I'm pretty certain that the UK model is just labelled H815 (mine certainly is). There's no "it's an EU 'phone, here's the EU suffix", it's just "H815", whether that's reported via the OS or on the sticker under the battery.

Heyho.

First, thank you, BySezerSimsek, for making this available.

Now I have a question for your ppl.

After I have upgraded to Android 7 with this, I can only activate the "High accuracy" location service.

I have not agreed to the consent dialog in Android 6, so I wonder why is it not showing up now.

Even when I switch to "Device only" mode and then deactivate and activate it via the toggle in the top bar, it goes straight back to "High accuracy".

Is that so with you, too?

I have already tried to delete all data of the "Google Play Services" app, but it did not work.

Hey good news for Lg g4 Indian owners, FINALLY you can get volte natively working

**********************************************************************************************************************

my device LG G4 H818p ,NOTE if its not work for you you can't downgrade easily you need to flash with H818P_MOD.kdz then flash your device stock ROM

**********************************************************************************************************************

First you have to flash with with H818N10e_00_0112.kdz(5.1) to H818N20h_00_0926.kdz MM then with H818P v29a TOT file

and then the TRICK STARTS HERE

wait at startup at-least 10 min or more ......

Don't select any language and DON'T touch your phone

wait until you see volte on top status bar

after sometime you continue the process

you will get Jio Volte ,even video calling also working

If you get slow internet ,change to band 3 or 5 using *#546368#*815#(even if you had 818)

changing band will lose volte for 1min then comes back

band selection is subject to coverage you may loss signal of band 3 or 5 otherwise leave as it is

Exactly!

- Open up winhex

- Open the .tot file in winhex

- Search for all occurrences of 'echo 1 > /sys/devices/system/cpu/cpu4/online'

- Change each entry you find -> 'echo 1' to 'echo 0' (you only need to change a single character for each entry

- Cant remember exactly but there are several places to modify, just keep finding them until there is no more

- Now do the same for all occurrences of 'echo 1 > /sys/devices/system/cpu/cpu5/online'

- Save the file

- Flash
