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.

I just purchase a Samsung galaxy A50 SM-A505U at Ebay from xfinity, I havent received it yet but I was wondering if this specific model from xfinity when you insert a sim card from another provider will asked for a unlock code?
I have a verizon samsung a505u I want to root but am kinda new to all this. Will someone provide all necessary things I need and steps?

I have an A505U as well that's recently off contract and I am trying to root it, not having any luck though :'( My OEM Unlock setting is missing in the Developer Options as well; none of the common methods for getting it to appear work :/
I have been trying to unlock a Samsung Galaxy S9 T-Mobile model SM-G960U to use it on local carrier (Ecuador) with no luck (I have use doctorSIM service too)
After booting the phone a got a message:
Security error.
This phone has been flashed with unauthorized software is locked. Call you mobile operator for additional support. Please note that a repair/return for this issue may have additional cost.
Trying to use the T-Mobile device unlock app, then a screen shows up with a message "Your device is network locked at this time, which prevents it from operating with other compatible wireless networks. To inquire about your device's unlock eligibility please continue" but after tapping the Continue button there is not option of permanent unlock, I got a message saying: "Server not responding. Please try again later."
I have trying to install de stock firmware G960USQU7ETG3_G960UOYN7ETG3_TMB (Android 10) downloaded from Frija using the Odin tool, doing a factory reset, wiping the cache, doing a NAND Erase with Odin, but the security error still shows up.
The device is able to browse on websites using Wi-Fi, what should I try next?
paid services are the only way. You won't get help on that here. They employ a different type of lock than most devices.
@OP
I don't know all the ins and outs of tmobile unlocking (not a fan of their service). However, I recently had in hand a paid off s9+ which was still locked. I ran the unlocking app multiple times over the course of a few hours. Each time it came back with an error (unsuccessful or something to that effect) when I tried the permanent unlock. For each attempt the tmo sim with active service was still installed. Eventually it did finally unlock. I'm not sure if a tmobile sim with active service is a necessity. Probably is as it has to authenticate the account for unlock eligibility.
I have a Verizon Samsung Galaxy S9 Sm-g960u and needed to switch to T-mobile. I had no problem switching from one carrier to another because I was told that all Samsung Galaxy S9 devices came factory unlocked. I bought a T-mobile Samsung Galaxy S7 Note from a friend and tried using the T-mobile app to unlock the phone I think there was a problem so he just called T-mobile and explained that he sold his old phone blah blah blah and since he owned it they just unlocked it right over the phone, no problems or issues.
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).
I've purchased a Verizon unlocked Galaxy s21 FE and am trying to use it on Mint Mobile. It connects for about 5 minutes but then 5G and reception go to 0 and a message saying "sorry, your device can't be activated on another carrier's network right now. For help, contact Verizon." pops up. I believe I could solve the issue by changing the CSC region code but don't want to trip KNOX. These are things I tried:
Phone Dialer */# commands did not work to change CSC or even show IMEI. Might be Verizon locked or Android 12 locked.
Flashing XAA region firmware did not help the issue even though it cleared all verizon bloatware and splash screen.
Flashing another carrier's (Tmobile) firmware and accidentally updated my bootloader to Binary 3 .
I believe that a potential fix is to flash android 11 from Verizon and maybe the phone dialer commands will work to change CSC.
Anyway, this has been a real headache and I just want to use my phone like normal on my selected carrier. Be careful with phones that have VZW region codes!!!
EDIT: I have the SM-G990U Snapdragon US model of the Galaxy S21 FE. Android 12 and 4.1 UI.
EDIT 2: The OEM Unlock Option does not exist on my phone even after becoming a developer.
You ever able to get this working?
