if its the 960f, then yes. it should be
Exynos - Yes, just enable OEM unlock in developer options, this will wipe the phone, there are instructions to make the process less of a pain if you read the dev threads
Snapdragon - No (Other than a couple of Chinese variants)

Simple question but can't really find the answer online.
Bought an H815, no carrier label etc. My ATT sim works in it.
I want to unlock the bootloader (OEM process) root, add TWRP and flash custom ROMS. Will this affect the factory unlocked carrier status?
How is it carrier unlocked btw , at the hardware level or bios type process? I see the H815 comes factory carrier unlocked?

Assuming your phone was purchased sim free, then no, bootloader unlock shouldn't affect it. You can always make a backup with SALT first (bootloader can be locked when you take the backup) so if for whatever reason it does get removed then you can restore it.
Btw, LG's don't support fastboot oem unlock. You need to do it via Official LG bootloader unlock website or UsU (look here in the threads) if your device isn't supported officially - if it is an EU H815 it official should work though.
fr eBay sim free. I'll look into the SALT backup.
I did a bit of work already and signed up as an LG dev and do see the LG website process which I was going to do to start.
So then adding TWRP and a custom rom will not affected the carrier unlock as well?
thanks

I saw an international version of the ZIP package coming out. OTA cannot be upgraded directly.
What should I do?
thanks.
I prefer to FLASHthe Xiaomi International Edition ROM, which will retain more of Xiaomi's features.

Unlock bootloader, flash twrp, flash the global zip mentioned several times in the forum. Better with EU chinese ROM as more features than global

Thank you, but I saw the EU version of the ROM, can not re-lock the bootloader, do not know if there will be anything bad.

Correct. If you try and lock the bootloader on the EU Chinese ROM or Global it's good bye phone.
If you don't unlock bootloader you'll be stuck on the Chinese ROM forever.

Why would you want to lock the bootloader?
Well?

Well what? If they want to lock the bootloader they can lock the bootloader.
That doesn't answer why! if it bricks the phone it might be useful to understand the process a bit fuller. I'm buying the Chinese version myself so want to be aware of why you'd want to lock the bootloader again

Return to stock, to sell, improve security, warranty etc
You'll only brick it if you install and lock the global ROM on a Chinese device, Chinese rom on a global device, or lock on the Chinese EU ROM
Cool. So if I get the Chinese one I'll put the EU one on.
I don't think I'd need to worry about locking the bootloader for a long time. I want this phone to last a few years and it seems reliable enough. And the processes will improve all the time.
Thanks!

Locking the bootloader is for certain applications and features that requires a more "secure" phone, since an unlocked bootloader is considered not "secure".
Payment Applications, Banking Applications, and DRM applications (Netflix) and such requires the phone to have a locked bootloader, or it will not work.

Are you forgetting Magisk? I'm unlocked since surviving 72 hours of stock locked hell. All my banking apps and Google pay have worked for the past 2 months.
BTW stock Chinese or Dev or Global are garbage compared to the EU version anyways.
I'm wanting to install twrp n attempt to root I've been waiting for the oem unlock to appear for it never to appear so I went into download to check the two states n they is no RMM state prenormal/Normal or OEM lock yes/no they are not there I only have FRP Lock n KnoxGuard n few other not important tags

In most situations yes mostly in the us snapdragons but a lot of international ones are unlocked my main question is all videos of s9s I've watched when in download mode it will show rmm state prenormal and oem lock yes what does it mean if these do not show in bootloader
If these to states are not appearing in download mode bootloader info is there a chance it's naturally unlocked

As of my knowledge "fastboot oem lock" will destroy the system image if it was modified.
I think your info is incomplete !

"Starting with 2018 models (and more recent), there was a regional separation of models at the bootloader level. "Chinese" versions of phones can only have a locked bootloader with Chinese firmware on board. "Flip Flops" do not take into account. It is impossible to block the bootloader on the "Chinese" body when the global (Russian) firmware is installed, get a "brick"."

I am sorry but I didn't get what exactly you are saying. Let me give more details. I have Indian variant of the device. Suppose I unlocked the bootloader, installed TWRP and flashed some custom rom. Later if I wanna relock the bootloader, what exactly I am supposed to do.

To do this, flash the miui fastboot rom via XiaoMiFlash and make sure the "clean all and lock" option is selected.
Of course, this means that everything on your phone will be erased - the phone will be restored to its factory settings as on the day of purchase.

1) If your device came with a Chinese firmware out of the box and you cross-flashed an Indian or a global you should not re-lock it.
2) If your device came with an Indian or a global firmware and you cross-flashed a Chinese firmware then you should not re-lock it.
3) If your device came with an Indian firmware and you cross-flashed a global firmware then no problem with.

I'm assuming before re-locking bootloader, you have to flash stock rom and stock recovery appropriate to your phone model?
Yes, it's mandatory to re-flash the stock ROM which previously was into device, assuming that it's used MiFlash tool both things are done in same operation.
Hi.
So I just bought a T-Mobile 9 pro online and I go to unlock the bootloader, and it won't let me ! I've tried the ADB command and it gave me an error saying it's not allowed. Then I turned the phone off and tried the button sequence to get into it. But there is no advanced option from recovery to boot into fastboot.
Just so you know. I'm trying to convert it to international ROM as I have done before with my other OnePlus phones.
Is this a common thing with T-Mobile ?
And how can I get the bootloader unlocked ?
Thanks
Oem unlock and usb debuging enabled in dev settings ?

If you don't have your unlock token from T-Mobile, you will need to use the Tmo->Eu MSM conversion tool to convert to EU. Then unlock bootloader there and go on to global or stay on Eu. If you stay on oos11 or 12, flash nonhlos modem back in.
You should back up modemst1/2 and persist/efs to be safe
