Flashing, rooting etc on H815 twn - G4 Q&A, Help & Troubleshooting

Is it possible to flash custom ROMS to this variant that has yet to have an unlock bootloader? If so, is it through flashify? but what about wiping the dalvik cache?
noob here lol
really wish LG would provide the damn unlock key. ugh

seems like you may have the G4 that cant be unlocked.. so thers no way.... you could root and install xposed but on LP only... with locked bootloader.. only a few h815 from some countries can be unlocked..

Bootloder unlock

How can I bootloder unlock my lg g4 "TWN"
my phone does not support bootloder unlock
so what can I do?
You can wait or do some research and write a bootloader unlock tool for everyone
...we are all waiting :/
You would probably be waiting indefinitely. It does not look like there will ever be a bootloader unlock for the G4's which are locked.

you can root yours if it is dual sim model . Forget unlocked bootloader .
My H818P is rooted with Lollipop.
But to Be honest, I'd rather have an unlocked bootloader :/
No root on MM and up is a pain.

Not sure but i think not possible, check General and development section please.
You can still root...I have h815 twn model, running 5.1 rooted...if you are on MM you need to use LGUP tool to downgrade to LP and then flash the rooted fw with flashfire...there are YouTube vids on it, just search

You can flash European kdz. But afterward you cannot receive bootloader unlock support
is it possible to flash a custom kdz of a different h815 variant that is already rooted ive looked around for pre rooted but nothing for h815-v20i-sea-xx just v10d euro id really like something with the latest security patches that i can install adaway and a layers theme idk maybe a temp root would work or i am hoping for a lost cause? i dont wanna brick this thing
Here, take a look at this:

LG G8 firmware flash

I just purchased a Verizon LG G8 that is unlocked and want to use it on Metro. I haven't gotten the phone yet but I would like to (if it's possible) flash a unbranded firmware. I'm confused about whether I can use LGUP or LG flash tool to do this. Can someone please tell me if this can be done and if so what is the best firmware to flash to have it unbranded with minimal bloat?
I miss the good old days on XDA where people actually came on XDA and there was always someone able to help out. I feel like that doesn't exist anymore. Too many phones and too many different carriers.
I don't think there's a patched LGUP to do this for LG G8 yet.

Holy shiit, someone actually answered my question! That is insane! Thanks for the info man!
Is there a y method that currently works to flash firmware on the LG g8? I would like to flash the stock unlocked carrier unbranded firmware.
There is no way to flash through LGUP or any other tools currently but you can unlock boot-loader root and install firmware package through twrp but doesn't work for T-Mobile or Metro

There is a thread for it and same thing at the g7 thread. Just use octoplus jtag pro to flash the v35 engineering boot-loader to device and from there you can unlock boot-loader and do all the stuff. If you dont have octoplus jtag pro there is a guy who will do it for you he charges i dont know how much though.

I have a question with my device LG G7Thinq

If I have a Korean lg g7 and I want to put a rom from my region, can I do it directly with the lg flash tool? and do I have to have the bootloader unlocked?

Yes, use crossflash guide. And You dont need unlocked bootloader.
