Thank you very much BySezerSimsek, it works great. You gave my LG (H818P) a second chance -> I was about to buy a new phone (not LG ;) ) And thank you ZmisiS for giving detailed installation instructions. I'm really happy now :victory:
[G4 Android Development] :
You're welcome.
[G4 Android Development] Dmitrij_Vitalis:
my 818p stuck in 11% progress and now it wont boot at all,fyi i've been doing exactly what the tutorial said :crying:
[G4 Android Development] :
Download Nougat 7.0 for LG G4 H818P, LG UP and drivers for your phone. Install drivers on your PC. Turn off the phone, take out the battery, return the battery, press button for UP sound, connect phone with PC and wait for download mode on phone. Go in LG UP, select Upgrade, add install package of Nougat 7.0, now select Refurbish and Start. Wait for finish.

Before, you need option for developer. Go in Settings > About phone > Usual > Information about software > 7 times click on Build and you will get notification you are developer. Now go back on Settings and go in Option developer and check USB debugging.

Yes, I have done exactly the same as you told me, but i'm getting error on 11% mark that says something about GPT and a warning error = 02000.. i can't remember.. lol anyway i'll send you the screenshot after i got home, thanks
[G4 Android Development] Dmitrij_Vitalis:
so, after losing certain amount of hair over my head, i went cheeky and threw away my USB cable and go to the nearest store to get me another one and flash the phone again

it works... mai oh mai.. the devs are doing such a great job.. I'm on Nougat now

BySezerSimsek and ZmisiS many thanks to you guys, yer a legend.. ;)

About cores

Thanks everyone who developed this thread. Since i cant unlock my bootloader i will try this update but i have few questions. I am having big warming up issues on my h815 and battery drains very quickly so can anyone say the performance of Nougat for me ? Is it getting hot too much ? And if theres some problem updating how can i turn back to my stock ?

Edit: I found the winhex eidt ways to disable big cores and now will try the flashing.

Thanks for everything i used winhex to disable big cores and updated tot file using lgup withiout problem now my device is working on nougat smoothly and doing app installs. İ checked with xpu-z and my 4th and 5th core is looking stopped i think its okey but for now my device is hot. ( just updated and doing some app insstallations ) Perfect guide thnx again.

NOTICE: If you have Windows Update deactivated, activate it to Manual instead of Automatic first, then install LGUP.

Deinstall your LGUP via uninstaller and delete the complete Folder.

For reinstalling LGUP you must install the DLL via its own installer first, get it from my GDrive:

https://drive.google.com/file/d/1he3Gp-PM8J3LuoEEuKnlkzgqQTbwD4mc/view?usp=sharing

After installing the DLL install LGUP by its installer:

https://drive.google.com/file/d/19X9rXwyo-4RXvQ1cuFaPWC9bVR7sKX2J/view?usp=sharing

After installing is complete deactivate your Windows Updater again.

Hope that Help you out.

---------- Post added at 05:14 PM ---------- Previous post was at 05:04 PM ----------

The error 0x200 says normaly you have a incompatible dll in LGUP Folder.

Please check this:

C:\Program Files\LG Electronics\LGUP\model\8994

Right click on LGUP_8994.dll and go Properties click on Detail Tab and look for Productversion, it must be 0.04.0

If is not 0040 then grab this dll from my GDrive:

https://drive.google.com/file/d/1KRcuslcxmcNTLgzjbMkCJzX1d-VMt8Vr/view?usp=sharing

Now its should working for you.

When I try to flash it directly via "fastboot flash recovery twrp-3.2.1-PREVIEW-96_g4_N.img" it says "writing 'recovery'...

No the rom is perfect.

I realized that only one of the sims can run on 3g so whatever sim you choice for mobile data that sim will have the options to change the network and if you switch the data to the second sim then the second sim will have 2g/3g options.

Just try it.

You can change the preferred simby going to settings then dual sim cards its the first option in settings the mobile data and set the sim of choice

I hope i helped solved your issue.

[G4 Android Development] marcelmmx:
Brilliant

Hello,

just a quick thank you to the poster. I updated my phone yesterday and I feels like I have a completely new phone. The battery life is incredible in comparison to what it was previously, the phone feels much snappier, and in general, all the issues I had just vanished. For example, my phone would hang for 5 seconds every 65 seconds and I could not figure out why - it's not even one month since my last factory reset and I don't even use that many apps - perhaps 20. I was trying to uninstall one app after another, nothing helped. Until I came across this thread, that is. I absolutely don't understand why LG did not release this Android version to all the G4 models worldwide - especially since they apparently worked on it and finished it, and it's so good. Anyhow, thanks to the author of this thread and if you have any problems with your G4, go for this one. Btw. I have the H815, in case you are wondering.

[G4 Android Development] andrehj:
I understand this topic was for phones with a locked bootloader, and I think you need an unlocked bootloader for this procedure. So am I missing somewhere the step to unlock the bootloader? When should that be done? Or am I mistaken?

I have a European H815, if that makes any difference.
[G4 Android Development] Foto-AG:
Yes you need to unlock BL first.

To get the unlock.bin from LG go to LGs Developer Page and follow there the steps.

[G4 Android Development] Jostian:
And you'll only be able to do that if you have a European variant.

Can i use hex editor to edit the h815 int. To h815t variant ?

And how to do it please reply.. It will realy much appreciated
[G4 Android Development] andrehj:
Thanks for your reply. I already unlocked my bootloader twice (I'm on my third G4, two died with bootloops :( ), but as I understood this topic, I cannot install Nougat (with the method from the topicstart) with an unlocked bootloader.

Therefore I think the correct order would be:

(With still locked bootloader) install Nougat according to the instructions from the topicstart and post no. 33.

Unlock bootloader via the link above.

Root (with your instructions from post no. 198)

Can you confirm if I'm correct?
[G4 Android Development] Foto-AG:
Nearly correct :silly:

I can do updating my MM 6.0 with unlocked BL with the Nougat tot file in Post 1. So i don't understand why the Thread starter says only possible with Locked BL.

Its surprised me thats working with unlocked BL too. I ve never ask for that, its runs with unlocked BL for me too.

May be if you do a Refurbish with the 7 tot file it could be to work only with a locked BL. Never tested out. So its up to you and find out yourself :angel:
