Project treble, could be a change in the galaxys story?

Hi guys, i leaved galaxy's universe after i've sold my galaxy s6 which i used to mod without tripping knox thanks to a particoular bootloader. Now i want to buy an s9, i know that bootloader trick maybe can be impossible, but with the born of project treble we can get an aosp?
I've notice that samsung has implemented a system that deny users to flash diifferent regions firmwares.
I leaved samsung scene, So can anybody clear my ideas about the current situation and what is expected for the future?

I don't know!

I've been searching for an answer to this, but I can't find anything. I think we are just going have to wait till they come out and see. It boggles my mind that they don't at least let the unlocked US version be bootloader unlockable.

from my understanding, Treble won't do anything for you on a Snapdragon variant, it will only be good on the Exynos variant where you can unlock bootloader without issue.

Possible to change T-Mobile S9 to unlocked? Want security updates from Samsung

I've got a T-Mobile S9 that I'd like to convert to unlocked so that I can get Android security updates directly from Samsung...I'm guessing that there are two steps to this:
1. Get the phone unlocked from T-Mobile carrier.
2. Flash an unlocked firmware image on my phone.
Which raises some questions. First off, if I do this, will I start getting security updates directly from Samsung? Is there anything additional that I need to do to get this started?
My next question is where can I find an image for the unlocked Samsung S9 firmware that I can flash? Is there a procedure for doing this somewhere? I've been looking around and haven't found anything relevant. So I obviously haven't looked in the right place yet *smile*.
I expect that my next step is to look at the postings for the Samsung S8 and see what's there for that. That might give me an idea of what's out there and what I can expect if I do this.
Thanks for any help.

i did this on my at&t U version, now on U1, everything works just fine, but i'm not sure how fast the U1 model get the security patches compare to the exynos, we're on april and i'm still on february patch

Noob S9 Questions

Coming from a OnePlus3, which was easy to root and had tons of ROMs...
If I want the same with the S9, I need to buy the international version unlocked, correct?
Also I saw in the S8 thread that AOSP ROMs are not easily available, or still being worked on but OK for S9?
I'm looking for good hardware that I can root and debloat (titanium backup is a must for me and has saved me countless times).
I prefer the S8 because it is cheaper but not if AOSP is a problem.
Thoughts?

S9 has RMM implemented, long story short its a new feature of samsung that prevents you from flashing custom binaries (TWRP Included) to the phone for the first 7 days of using it.
Once you get your phone, finish set up wizard, connect a google and samsung account and wait 7 days for the OEM unlock button to appear. There are AOSP roms for the device, namely RR and Lineage OS.

I came from a oneplus 3 running AOSP resurrection remix 6.0 to the galaxy s9 a few days ago. I've been flashing phones for many years now, so I'm well versed in initially gaining root/custom recovery. This phone was a breeze to flash. The root guide in the tutorials section of this sub forum was great. Just make sure the usb drivers are on your pc and you follow the instructions exactly. I had resurrection remix 6.0 running on my galaxy s9 (exynos) in 10 mins after opening the box! [emoji106]

Thanks to you both. There are two international (non-US) variants - one with Exynos and one with Snapdragon.
Only the Exynos can be bootloader unlocked, correct?

I'm unsure about the bootloader abilities of the snapdragon variant. I only have the Exynos personally, which is unlockable.

Thanks. I got an answer in this thread: https://forum.xda-developers.com/ga...-g9600-bootloader-question-t3795978?nocache=1
There is no TWRP for the snapdragon international variant so I will definitely stay away from it.

Can I unlock and root G988U1?

Hello, I'm trying to sell my Exynos s20 but idk if this G988U1 has the support for custom rom and root. As I've read, the Snapdragon can be unlocked only by paying a fee, is this true?

no-one has uncovered how the warning screens work yet on the snapdragon versions.

Confirmed still working on OneUI 4.1

Could you please make or create the mod works with the 5G SnapDragon version!?

Still working for me. Saved my night
