I have a Verizon Galaxy S9 (SM-G960U). Two questions for the experts. Is there anyway to unlock the bootloader? Is it possible to downgrade from Pie to Oreo if the bootloader versions are different?
No

Is this a situation where no solution has been discovered yet, or is this new technology that will never be conquered?

Both, you would need the encryption key from Samsung to unlock it, never gonna happen
If you want an S9 to root and play with, buy the International Exynos version, comes already unlocked ready to go
And you cannot downgrade the bootloader on either versions, once you're on a BL version higher than Oreos highest version, you're stuck

Sorry for this if it is answered elsewhere but I didn't see a specific answer in my search.
I'm looking for the unlocked international version of the S9 because I want to root it, flash ROMs, etc..
I see the international SM-960 models that have the Exynos chip, which I know can be unlocked.
I also see the international SM-G9600 models that have the Snapdragon chip. Can the international variant with Snapdragon also be unlocked, or is it Exynos only?
In some strings I've seen mention of getting an unlock code from Samsung after 7 days. Is that for the 9600 (snapdragon), the 960 (Exynos), or both?
The SM G9600 has an unlocked bootloader like the exynos variants, but since there is no TWRP for the g9600 you kinda can't do much with it. There are no custom ROMs out there for the snapdragon version. But there are GSIs that can be installed thanks to Project treble. But like I said, without twrp you can't do much.

Hi, I've bought an 960U in the USA, and looking to flash the Brazilian ROM, but the variant used here is the 9600. Can I Flash It?

No, the SM-G960U (AT&T carrier locked version, IIRC) has a locked bootloader. I do not think you can flash any new firmware to it, unfortunately.
EDIT: Maybe you can, follow the guide in this thread: https://forum.xda-developers.com/galaxy-s9/how-to/how-to-flash-u1-firmware-to-device-t3765200
I'm not sure, but it may be worth a try.

Hi
I have the 960u unlocked, I bought it in a best buy.
This makes a difference to flash or not the 9600?

Carrier unlocked is not the same as bootloader unlocked. One let's you use any carrier SIM card the other let's you flash stuff.
I can buy the N9600 but I am not entirely sure if it will be able to get fully twrp working and root
I have an AT&T nash and I was wondering if it is possible for me to flash stock pie
There is no pie for nash xt1789-04 (att) but there is pie released for other z2 force. Will it break my phone if I flash pie stock over ATT stock rom? If so, can I have a link to the pie rom?
There's no stock 9.0 for any model. GSIs and custom ROMs are available, but an unlocked bootloader is required for either route. Users of the ATT & VZ models must wait for Moto to rollout Pie officially.
If you're interested in those things I'd strongly recommend selling your ATT Z2.

Oh, I thought pie was out because on gsmarena it says it's upgradeable. I guess it's wrong.
But when this does come out, for let's say, Sprint, is it possible for me to flash a sprint rom to my ATT MZ2F?

Moto released their update rollout. Among the phones slated to receive Pie you'll find the Z2 and Z2 Play.
Sure, you can try to flash the official build on your Z when it's out. Just keep in mind that the phone will probably lose LTE, and possibly other functions.
Ok thank you for answering

Normally, yes you can flash from a different model (i.e. Sprint FW on TMO model), with the exception of the AT&T/Verizon variants, which are bootloader locked, and you cannot flash anything (not even official firmware) on them.

That's wrong because I was able to flash android 8.0 att over 7.1.1 because it wouldn't let me update normally. I'm pretty sure you can flash images with the same stock signature, but I'm asking if it's possible to flash stock firmware from another model on to att phone with bootloader locked

Maybe I wasn't clear enough, I meant official firmware of a different model.
Hi all.
I've bought an S9+ off Ebay in the UK and assumed that I'd be sent a UK model but instead I've received a USA AT&T Snapdragon version.
I've been on xda some time now and am used to rooting and flashing roms for UK versions but not the USA versions.
Does anyone have any advice as to what I should do? Ideally I'd only want to root it but unsure how to approach it. There doesn't seem many ROMs for the Snapdragon version!
If I do successfully root it and don't flash a custom rom, will I still get official updates?
Thanks!
No root or custom for Snapdragon US model S9s, Bootloaders are locked
You need the international Exynos version

that shouldnt make any difference whatsoever. i have brought several phones from the US to several EU countries, including the UK and never had any issue with US phones working over there and using europe specific apps as well. Should be fine.
Hey guys, i'm about to buy an Moto Z2 Force for a good price, but i have a doubt, the model number is the Xt1789-04 from at&t, so i was watching some post here about the phone and theres another z2 force with the same model number, the Tmobile and another model, the Xt1789-05 global, i'm the kind of person who love flashing things, roms, kernels, so i can flash roms, kernels, gsi roms and others with the at&t variant or i will be limited to keep the stock?

ATT and TMO are both -04 but only the TMO is bootloader unlockable, not the ATT. However, both are stuck on oreo, no official pie, but there are pie roms for the TMO.
The -05 is bootloader unlockable and has pie officially, plus can run roms.

Right. As of now there is no known way to unlock the bootloader of an ATT model.

The first step to rooting a device is unlocking the bootloader to allow modified or custom images. Unfortunately, Samsung Snapdragon devices are generally NOT able to be unlocked.
See this guide. If the OEM Unlocking toggle does not appear, your device cannot be unlocked.
