Custom Roms - LG G8 Questions & Answers

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.

It'll be possible at some point, but don't expect anything too soon.

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.

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...

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.

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!

Question regarding rooting Unlocked T-Mobile LG G7

Hello everyone, I am unaware if this is possible, or not. If I have a Lg G7 that I've bought outright from T-mobile, and can be used with any phone carrier, am I able to root it as an unlocked factory unit? Any help would be appreciated. Thanks!

Only LG g7 from Europe (g710EM models) can be bootloader unlocked. Also the T-Mobile model has been known to cause problems with whatever custom development is going on here.
As a normal stock phone it's ok. It's just not development friendly

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

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.
