Help flashing Custom rom on LG G8 820UM AT&T - LG G8 Questions & Answers

Recently got a LG G8 thinq at&t variant, we have the bootloader unlocked, but cant find any custom roms, and it seems at twrp doesn't support this model, so can't flash GAPPS, even if we did get a rom. Can anyone help? Thanks

can you tell me please how did you unlock the bootloader?

There are no custom roms yet. Someone has to make one. I'd take a crack at it if I wasn't retarded when it came to programming. Every time someone tries to help me I screw it up.

hello i'm new to the forum and i have a doubt, my lg g8 is blocked to use only at&t chip, if i do the bootloader deblocking and change the rom i can use another operator's chip ?, i'm in brazil and i can't use an operator local

Taiwan H815 model bootloader unlock help

Hey guys,i recently got the LG G4 coming from a G3
Trying to unlock the bootloader of this phone i saw that the Taiwan model that i have isnt supported
I am thinking of what i can do to unlock my device
I thought a possibility would be to flash the european image on my phone in download mode ?
Or enter a different IMEI to my device when LG Website asks me to enter it
If you guys have any luck with the other international versions of LG G4 please let me know
Thank you very much

I know a developer in korea they say all Internationals models of G4 will have bootloader unlocked although he doesnt recommend it but it will be available.. He may not be sure of other carrier varients currently lg is working on it and its status will be available on their site when finished

Its one of those ill believe it when i see it. Now i know. There have been plenty of phones and tablets get unlocked officially and unofficialy 1.2.even 3 years later. I just know the encryption that the bls have on them and its bassicly unhackable. Thats why i say exploits. Unless someone finds the trusted key that lg uses. Which from what ive read. Is generated randomly from each iemi and android id. But i for one hope it happens and if ita any consolation that does revive my hope in g4 development. Lol i got a lg k7 unlocked and u can oem unlock then fastboot oem unlock. But theres absolutly no development for this device yet. Im bakin up a rom for it now

How to unlock bootloader without official method

Hi guys,
I have a LG G4 H815 with android 5.1 (Since the bootloop issue affected, im using 4 core fix). So it seems i cant unlock my bootloader from official method. When i enter Device ID in developer site it says "Unfortunately, your device (Singapore(ARROW(SINGAPORE))) does not support unlocking the bootloader." After some search i found that LG stopped giving bin file for this model. So are there any way to unlock this bootloader since i need to install marshmallow and the bootloader should be unlocked to to root marshmallow. If anyone knows to unlock bootloader unofficial way, please be kind enough to share it :3. (Sorry for my bad English)
Thanks! Have a good day!

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.

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?
Btw if it says my devices are lg g4 and lg g6 i put lg g6 to take the place of my lg q6 cause there's no lg q6 option. So now you know

Yes - Virgin is on the Bell network. If you want to step up your gain with the G4 H812 - see steadfasterX's thread:
[UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU
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.

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 ...

Custom Roms

Hey Developers and Enthusiasts,
I'm new to the forum and wanted to ask around if anyone has had any luck in flashing the LG G8 ThinQ with either Plasma Mobile or with LineageOS. I'm looking into both and have only seen up to the LG G4 but am wanting to either help someone look more into it or venture into creating a custom ROM myself. Any help or direction is appreciated. Happy Developing!

Since the bootloader cannot be unlocked on the G8 that isn't possible at the moment.

The OEM is able to be unlocked on the Sprint g8 I have, but I am having trouble accessing the bootloader menu. Is that what you mean by it's not able to unlocked or is there a way to access the bootloader menu that I am missing?

That option doesn't mean bootloader unlock.
The boot loader for the G8 is able to be unlocked by using a G850 engineering abl_a.bin file . https://forum.xda-developers.com/t/...nlock-and-magisk-root-using-firehose.4221793/
There is an LG G8s Lineage 18.1 rom but it does not work on the G8, I am looking at it and it gets system ui freezes, wifi doesn't turn on, and there is a sim pin unlock requirement, other than that other functions work on my G8: https://forum.xda-developers.com/t/rom-lineageos-18-1-for-lg-g8s-thinq-betalm-wip.4219111/
I am looking for different roms since the lineage doesnt work but am not finding anything.
