Question about the bootloader, LGUP, LG Bridge and OTAs

Hello there!
I have a locked H815 and I've had many issues with it, especially when I upgraded to 6.0 and V20D. I've got it back from repairs and it's been downgraded to Android 5.1.
I saw that it's ok to use LGUP and flash 5.1 and 6.0 firmwares and that doesn't require an unlocked bootloader nor root.
Now, I want to ask if I unlock my bootloader, will I still be able to receive OTA updates? Or updates through LG Bridge?
Also, if I install a custom ROM right now, will I be able to successfully flash the stock firmwares and have the phone as it was just with an unlocked bootloader?
Thanks!

Help! Any way to root g4 h815 twn-xx with 6.0 v20d locked bootloader?

Any thoughts on the best way to go to get this phone rooted? Back to LP? Any pre-rooted image for 6.0 V20d? Any help will be much appreciated. Unlocking the bootloader is not available on this model, I guess I can live without it. I just want to root it.
Thank you guys!

Rooting H815T Marshmallow

Hey all. So basically I recently purchased the H815T Australian optus model. It was initially on Lollipop but updated to MM & I need root so I can restore all my data from my previous device but seems I need to unlock the bootloader. Unfortunately it couldn't be done because the H815T isn't supported on the LG unlocking website. Is there another way to unlock the bootloader or rooting it? Please help guys, I really need to retrieve my data but can't do so till there is a method to root. Or would I have to downgrade to Lollipop & root? I'd immensely appreciate some assistance with this, cheers.

Thanks for your help. I really enjoy being on Marshmallow so don't really want to downgrade. Thankfully I got most of my whatsapp messages through google drive backup & most of the other apps did have some form of cloud storage. I'm gonna stick to MM till a rooting method does eventuate.

Do I need to have unlocked bootloader to downgrade?

I read online downgrading on locked bootloader will brick the phone, but for G3, specifically sprint, none of tutorials on downgrading mention anything about bootloader. So does it mean you can downgrade G3 even on locked bootloader? Specifically Im asking about Ls990 sprint model, if downgrading from firmware ZV6 to ZV4? Or Zv8 to Zv4? Thanks

It's my first time to hear downgrading a device would brick the phone... It would either be a success or a fail(will abort and nothing will be changed). It should work via kdz, unless lg did something to prevent a downgrade.

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.
