Do all S9s with model SM-G9600 have the bootloader unlocked? - Samsung Galaxy S9 Questions & Answers

I am thinking of buying an S9, I read that the SM-G9600 with Snapdragon had the bootloader unlocked, but before I purchase I want to be 100% that all phones with that number have the bootloader unlocked and not just ones from specific regions. I've seen a few on eBay with that model number, but I only want the phone if I can install Lineage on it.
Also if anyone can share their experiences with a LineageOS custom ROM for S9, I'd appreciate it.
Thanks

Certain models have unlocked bootloaders, certain models don't, you do not get the same model with locked and unlocked bootloaders
But if you're looking for custom ROMs, why not buy the Exynos instead?

I know some models don't have unlocked bootloader, but I am asking about SM-G9600 specifically, I want to buy one off eBay, but they say Factory Unlocked and don't clarify if they mean the bootloader or only the SIM. I am interested in running some emulators that don't run well on Exynos devices, only Snapdragon.

Factory unlocked would mean it's carrier unlocked not the bootloader.

Yes, but this article https://www.xda-developers.com/snapdragon-samsung-galaxy-s9-lineageos-15-1/, says SM-G9600 have unlockable bootloaders, though it mentions that it's from Latin America, I just want clarification whether all SM-G9600 are unlocked or only those sold in Latin America.

That's what I'm saying, it's the model that is unlocked or not, not the region, matters not where you buy it, it only matters which model you buy
All US snapdragon models are locked, a couple of Chinese Snapdragon models are unlocked, that is one of them iirc
All the Exynos are unlocked
Development-wise, no point going for a Snapdragon if you're looking to play about with custom stuff, buy Exynos, for the sake of an emulator?

Enough of this nonsense!
Yes, the SM-G9600/SM-G9650 (Latin America / China version with the Snapdragon processor) are all bootloader unlocked. You absolutely will need to root and flash support files for your carrier to get VoLTE (2G and 3G fallback will not be available from carriers soon as they're all shutting down their old 2G/3G networks) and possibly WiFi calling to work. If you don't already know, you will trip the Knox hardware e-fuse and the void the phone's warranty by modifying the stock ROM. This will also mean the phone will permanently lose access to things like Knox features and Samsung Pay, so do some reading.

[Q] Root Question - SM-N9108V vs SM-N910V

I obviously realize that as of right now, there's no root for the Verizon Galaxy Note 4, retail version (SM-N910V).
However, there are other countries' versions that have root. Are any of these, Verizon? I realize that we have the SM-N910V. But, what is the SM-N9108V? I'm looking at the list of models which Chainfire's exploit would work for, here. Is the Chinese version on Verizon (hence the "V" in the model #SM-N9108V)? Is IT locked, as well? If so, how is it able to get root and we (on the retail SM-N910V) cannot?
That said, if the SM-N9108V is much like our retail SM-N910V in that respect, locked bootloader and now rooted...would Chainfire's exploit for the SM-N9108V work for the SM-N910V if we just somehow modified our GPS location (through an app like Fake GPS)?

Question: What's the difference in the two models? Anyone know? Do BOTH have locked bootloaders? I'm a bit of a n00b, so I'm guessing a locked bootloader on the SM-N910V is the whole hold up on the root situation, yes/no? Just wondering if the SM-N9108V is the same in that respect. I don't know if the "V" on BOTH models indicates Verizon or not and/or if they're both locked.
EDIT: Did a little bit of research. The SM-N9108V is a SIM-FREE variant. Don't know what all that entails or if that might help somehow (i.e. First using Fake GPS to say you're in China, removing your SIM Card, then running the SM-N9108V exploit???). Just a thought.
CF-AUTOROOT works by temp flashing a custom recovery, flashing root and then reflashes the stock recovery for the model listed. This procedure takes an unlocked bootloader. .......

GPS location would never matter in any exploit for root or bootloaders ever anywhere ever. How would your location on the planet somehow change the hardware and software of a handset? Honestly you thought the phyical location of a phone determins if it has a bootloader that automatically switches to be able to be unlocked? Amazing.

Best M9 Variant for Rooted User on AT&T?

I guess it comes down to which LTE bands are available and which carriers' phones can be BL-Unlocked. Please tell me if t his has changed, but I'm used to AT&T bootloaders not being unlockable, while TMO bootloaders are often readily unlockable but their devices don't always use the same bands as AT&T's network.
I'm pretty sure I want an M9. It looks like ATT/TMO hardware are the same, though I don't know which bands are available on their respective ROMS. I really want my device unlocked, and I might want to run a custom ROM at some point.
Is it recommended to get an unlocked TMO phone for use on AT&T, or does the TMO ROM limit the available LTE bands in any way? Or is there any reason I should just go with the AT&T version because, for example, it's easily rooted and/or there's a way to unlock the BL?
Thanks in advance.
Get the AT&T version.
HTC allows you to unlock the BL.
Sunshine allows you to S-off so you can convert it to the Developer Edition.
This is what I did, got the AT&T version through them then converted the Dev Edition

question about unlocked status/flashing ability

I'm looking to get an s9+, i know verizon will have theirs locked down
i see an "unlocked" version on amazon
SM-G965U1 is the model
is this just carrier unlocked or boot loader unlocked? can i flash kernel and custom roms with this model? if not, which model that will work with vzw should i get that can do that?
Thanks!!
You can only flash custom roms on the exynos models. Not sure how well they work on verizon

Change Modem (CP) for G981U1 for use in Europe?

...because I use the phone in Europe. Given the firmware is North America I was wondering whether I need to change the modem in ODIN to get better reception/ 5g in Europe. The last Samsung I owned was the S4 where updating the modem to your region was ubiquitary. Not sure if this is still necessary and doable., so hoping for some advice.
Second question: I have a US S20 locked to AT&T. Will flashing the U1 firmware (incl. factory reset) also unlock the phone?
Cheers!

You can't mix exynos firmware and Snapdragon. I doubt you can use just the modem portion of a European exynos code. You can flash U1 code freely, but that does not unlock the bootloader. Do you mean you can't put any sim other than AT&T?
I didn't mean to unlock the bootloader (since that's not possible for US phones) but the sim so I can use my German sim card in Europe in this phone.

Do you know if I run the risk to brick my device if I tried to combine the exynos modem with a snapdragon rom? Cause otherwise I might just try it.

unlock bootloader for g988u verizon

New to flashing and unlocking bootloaders. Accidentally came upon the download screen and wanted to learn more. I have a samsung galaxy s20 ultra 5g g988u but from Verizon. Ive read everything i could and still confused. Can anyone help me out with anything. Lol i just want to learn
U.S. variant of Samsung phones cannot be bootloader unlocked. Everything you read online most likely is referencing the international version, which can be unlocked no problem. The only way you can unlock a U.S. variant phone is by paying a service fee (search for SamPWND).
