H818P - what's possible now in 2023? - G4 Q&A, Help & Troubleshooting

Been away from the g4 but reading most recent looks like the g4 still is still relevant - except for the h818p.
So asking the devs… can the h818p get a chance for new development, at least unlocked bootloader, usu, and the like?

[Q] will LG G4 Comes with a option of unlocking bootloader

I should be getting LG G4 given that the specs they are using, my question is LG like Samsung which release varies same model like they did with S4, S5, also does LG G4 approve of unlocking bootloader etc?
Too early to know. The tmobile variant will likely be unlocked like the T-Mobile G3. LG could put an updated version of Loki on the G4.

Many H815 owners (Europe) have already unlocked their bootloader.
Visit LG.com , register as a developer and follow the unlocking process outlined by LG.
Back in May when I unlocked mine there was only the H815 on the list.
LG are rolling out the service to other G4 devices.
Monitor the list to see if the code for your device is available.
LG repeatedly warn you of serious issues that unlocking a bootloader may cause but will in the end email you your unlocking code.

LG US991 info please...

good day/evening XDA community,
I have a question about the LG G4 US991 variant.
Is it the same in terms of development, modding, rooting etc.?
Can you guys shed some light as to what is the major difference compared to the H815?
Can the H815 developments, rooting, modding etc. work on the US991
thanks in advance guys...
*bump* i am wanting to put cyanogenmod on my LG G4 US991 (US Cellular variant bought unlocked at Best Buy for use on TMobile network which works just fine) but also cant find any info over the H815. Help?

If you are still on Lollipop, it can be rooted with Low Effort root and you can install Xposed through Flashify. That's it, since there's no bootloader unlock. If you're on Marshmallow, you can't root.

I'd swap out your US991 for a T-Mobile H811 (which comes with an unlockable bootloader out of the box). You can only unlock the bootloader on International (non-US) H815s and the T-Mobile H811.
Hey ecaslak, I accept that deal. I have a two weeks old g4 US991 and I happily swap with yours.

Whether I buy LG G4 H818P or not?

Hello guys, I bought a LG G4. The seller today said that they have sent a H818P Dual SIM version. I already have an G4 H815 European Version and I wanted exactly the same one to easily unlock bootloader, root new ROM flash etc. after warranty period.
Should I send it back or should I accept it? What do you suggest to me? Will it be easy to find custom ROMs for H818P in the future (2 years later).
Also, is there any significant differences between them especially for my country Turkey? I have read some posts about rooting H818P with H815 ROMs. Are they easy to cope with? Or is it better to send it back.
Thank you beforehand for your suggestions.

Will the G4 in canada get nougat?

So I did some searching online and found that LG decided to update some of the eastern models to 7.0. My question is weather the models in North America will get nougat by OTA or if I can load it manually without root. I just got a brand new H812 model and I'm sick of the OS. Will flashing the official nougat for those models work on my phone?

It's looking increasingly likely that the H812 will not get 7.0 (you can check out the *****-fest on https://forum.xda-developers.com/g4/general/official-nougat-g4-v10-q2-2017-t3567402 to get a better idea).
I do not recommend flashing any other models of official Nougat - with the H812 locked bootloader and the model differences you will most likely hard-brick your device - I am not aware of any H812's that have successfully done this but will stand corrected if someone has managed.
Now with that said, do not abandon all hope. Senior member steadfasterX has been working steadfastly on overcoming all these issues and has recently had a breakthrough development (refer to post #252 in his thread [Bootloader UNLOCK][LS991|H81x|VS986|F500] Unofficial unlock -> PoC).
So hold on and wait for further developments and check his thread there regularly ... he had previously unlocked successfully an H812 but with some limitation but this new development may lead to all limitations and risks being overcome shortly.

Thank you very much
Exiting stuff!
No point in waiting any longer, lol - it is doubtful that the LG G4 will last much more than this year before they all are toast - either by battery or by the phone itself.

Nobody has had to wait. As of March 8 '18 were able to unofficially unlock our locked LG G4 H812 bootloaders, thanks to @steadfasterX 's brilliant & persistent work: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU
Not only have we been able to install a ported official Nougat stock rom but many of us have been using custom Nougat and Oreo roms. Batteries can be replaced and later LG G4 models have not suffered the ILAPO issues that plagued earlier versions.
Custom Rom for LG G4 H812
Can someone tell me where I can find a custom rom for the LG G4 H812? In particular where I can find the ROM for Nougat. I'm curious if I can go from MM to Oreo and skip over Nougat? Can I also go straight to Pie from MM? And if I find any of these unstable or unsuable, can I downgrade after upgrading?

Most custom roms have their own thread in the following forum: G4 Android Development and some of the very best can be found in SteadfasterX's Download Server - steadfasterX is the author of the unofficial bootloader unlock process for the LG G4.
Note: If you have not unlocked your bootloader unofficially following the process in the linked thread in post #6 ([UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU), you will have to complete that whole process first before you can install a custom recovery and rom. Read everything very carefully and make you you understand it fully.

Can i flash a bell kdz for virgin?

So i just got my old cracked lg g4 h812 canadian model to add to my phone collection seeing that my lg q6 is my daily driver and i can't root it and i wanted to get back into the android game with rooting and all that and i want to downgrade my lg g4 to android lollipop and i can't find any virgin firmwares. So will the bell firmware work for my virgin lg g4?

First and foremost: these questions have all been asked and answered in this thread:

Use the search bar in that thread for any other general ones you might have.
Yes - Virgin is on the Bell network. If you want to step up your gain with the G4 H812 - see steadfasterX's thread:

You can now unofficially unlock your LG G4 bootloader, install TWRP, root, AND flash selected H811 custom roms on the H812 following the process he outlines. Recommend you seriously consider it.
If you haven't carrier unlocked your phone: as of Dec. 1 2017, Canadian carriers cannot charge for it. Recommend you do it.

I use this site: http://phonefirmwares.com/lg-g4-h812-android-6-0-phone-stock-firmware-rom-canada-variants/ usually but it appears to be down right now. Hopefully it's not defunct. They do have the Bell versions. Yes, you can use the TELUS rom but may be preferable to stick with Bell for now and get your phone carrier unlocked, if you haven't already.
You want to be on Marshmallow if you are going to do the bootloader unlock process. It will give you so many more options and you can have root on Marshmallow if you want. You do not have to root first in this process, it comes after the unlock and TWRP install.

Site is up now: https://lg-firmwares.com/lg-h812-firmwares/
Just tried it. They changed their URL.
Scroll down to the latest 6.0 version if you plan to bootloader unlock and select a later version (later version e.g. z instead of a)

You'll have to Google for it then ... OR search the Canadian H812 guide thread and search Bell/Virgin there and see if a member can help you in one those searched posts for a kdz - you do not have to stick to the E version if there's a later more security/bug - free up-to-date one ...
