Noob S9 Questions - Samsung Galaxy S9 Questions & Answers

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.

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.

I'm lucky, italian version will be exynos... It's unlocked and i've read that it's also more powerfull

Version differences and bootloader

Just making sure I'm getting this right.
North american models are snapdragon and locked. -> possible to unlock with some debug mode which locks your battery @ -20% -> has a very quiet unofficial lineage port
Global/international are exynos and unlocked. -> has official lineage support
so there's no way to get a snapdragon s9 and it get rooted/custom rom without a hit to battery life?
No American model Snapdragons can be unlocked at all, only a couple of Chinese models, not sure where you read 20% battery and some lineage port because the bootloaders are locked, thus nothing custom can be flashed
Exynos are unlocked

I think the OP read some old Galaxy S7 or S8 info as this is my first Samsung phone since prior to the Galaxy Line existed and in doing my research leading up to launch of the S9 I came across similar details. Suffice to say that info gave me a false sense of hope that in time the S9 would be cracked. Hence I am stuck with this piece of crap.

Upgrade GALAXY TAB S 10.5 SM-T800 to the most recent Android version possible

Hi all,
I am the old owner of this device and was wondering to which latest possible Android version can I update it. Even unofficially supported ofc. Currently running 6.1.
Any helper links are welcome.
Thank you.

Hi, I updated my Tab S T-800 with Resurrection Remix based on 14.1 and it works really great.
Tried LOS15.1 too, but wasn't stable.

Guys, I have Samsung Galaxy TAB S (SM T805) if I update it to a newer version will it be faster?
Or if I root the tablet?

Newer firmware doesn't necessarily make the device faster. There isn't much you can do about a 9 yr old device.
Since the T800/T805 are not Treble compliant, the only way to run newer firmware is via custom ROMs, although I doubt development on devices this old gets much attention.
So what I understand is there is not much to do with the tablet to make it a little bit faster.
What about root or that is a different matter?

Root is a different matter. In most cases, you can flash the Magisk app through TWRP, and Magisk will automatically detect the right way to root your device. If TWRP is not available, you'll need to patch the AP firmware file in Magisk, then flash to your device with Odin.

Would you be able to suggest which old tablets could make sense to flash semi-current roms onto? I tried to bring back some old device to reuse for home assistant display, but it's too old... Been thinking about these samsungs, but from this thread it's also a bit too old.

I don't have any suggestions, sorry. I have a Galaxy Tab A 8.0 (T290) at home that I'm running an AOSP GSI on, but those were released in 2018.

imho it's correct that a custom ROM doesn't necessarily make old devices faster, but I experienced it such that at least they don't get slower (except I9195).
Recently I was allowed to support development of Android 19=LOS 20 for my T325 and it runs like hell.
P600 and P900 on LOS14, T810 on LOS19 all using daily in different rooms.
I9195 on LOS18 (that is really laggy) N910F on LOS18 as backup devices.

Unlocking the bootloader

I haven't really done much advanced stuff with android for a while and wanted to hop back in, but I cannot find the oem unlock option. I've tried doing the date and time thing, but that didn't work. Is there a new bootloader? I remember it always being just blue with no options, but the one I'm seeing is different.
*A little description of what it looks like when I boot into the bootloader just to make sure I'm not crazy: It has some info listed: (in red) FastBoot Mode, Product name- kona, Variant - SM8 UFS, Bootloader Version - , Baseband Version - , Serial Number - ***********, Secure Boot - yes, (in red) Device state - locked.
Pushing the volume buttons scrolls through 6 options, Start, Restart Bootloader, Recovery mode, Power off, Boot to FFBM, And boot to QMMI. The last 2 options and Start just boot it into recovery mode, I'm assuming I need the device unlocked to use these?
What device do you have? Is it Snapdragon United States? If so there will not be an oem unlock. You have to unlock through paid service and that depends on what device and what bootloader version your firmware is on.

Ive found out a little more, looked into Sampwnd and they weren't able to do it. I have the g988u and version 2 of the bootloader it seems. Is there another payed service that I can use for my phone and software? I have only been able to find Sampwnd.
Only bootloader 1 can be unlocked at this time. And you can't flash back once bootloader upgrades.

That's too bad. Thanks for the help. Will the bootloader ever be able to be unlocked? Or is it just not possible?
They are working on certain devices with later bootloader.

What version oneui? 3.0 and below can be unlocked I believe. I'm no pro but this guy is @afaneh92. If it can be done, he can make it happen. Reach out to him, he's super helpful. He just helped me unlock my S20 a couple days ago. Smooth as butter.

Unfortunately I have version 3.1, from what I understand they have updated the bootloader and previous methods don't work with the new one.

Bummer. Pretty sure you're correct. SOL until some smart individual figures out how to get around it.
I've got an S10 which is a version 6. The magic number is 5. Going to sell it while I can.
I'm looking into getting a S20 Plus and was told has to have B1 to be unlocked. I'm coming from a dead Galaxy S5 I have no phone at the moment. I just want a reliable devices that I can make received calls, texts and doesn't have camera issues (like the Ultra) and can be rooted. My S5 died it was having hardware problems and went into complete mobo failure cant restore or boot any roms anymore period. And I hope @afaneh92 can unlock if it has a B2. I'm looking at buying brand new from either Swappa or https://fusionelectronix.com/samsung-galaxy-s20-plus-5g-sm-g986u1-128gb-factory-unlocked/
I'm on Verizon hopefully unlocked phones will work on network? I may switch to T-mobile or another provider!
Hi, I am Android 11 and I opened my bootloader a few days ago, it is a very simple task

For s20 family, Bit1 is all that can be BL unlocked at present. Nobody has info on when (or even if) a Bit2 unlock will be available.
You can still find Bit1 s20 series in excellent condition on ebay, it just takes a bit of time. Clearly ask sellers what the last 5 characters are under Settings - About Phone - Software Information - Baseband Version.
I'm BL unlocked, rooted, running Bit1_Safe AP/CSC (the 2DUH2 Build Number).

Right.... I thought the only ones that had Bit1 have Android 10 according to this site? https://www.sammobile.com/samsung/galaxy-s20-plus/firmware/SM-G986U1/VZW/#SM-G986U1
Sooo say I get a S20+ from the follwoing site brand new how do I know if it has Bit1??? https://fusionelectronix.com/samsung-galaxy-s20-plus-5g-sm-g986u1-128gb-factory-unlocked/
And can these phones be be updated to Android 11, 12 etc....? What about any security updates?
Your camera does not have any focus issues and you dont get the "camera failed" error? Many Galaxy's had it including my S5. I'm sure this phone is a big improvement from it! I didnt like it didnt have OIS so pictures came out a bit blurry sometimes.

Ask any seller what firmware is on the phone. If it's a brand new, shrink wrapped, box, in some cases the firmware version is listed on a box label.
I went the ebay route, paid $432 including tax for a like new G986U. It took time, but I ended up with exactly what I wanted. For an ebay buy, recommend checking that the Sim and microSD readers work okay (Samsung has had some infant failure issues).
For any unlockable phone, I recommend that as soon as you have gone through setup you switch to airplane mode, disable Ota in developer options and run the 5 ADB commands to disable updater apps. Vzw can try to push a firmware update pretty quickly.

Wow your not rooted or unlocked BL? Well I mainly root so I can use TB to restore and backup my apps, call and text logs and install unknown apps.
I wouldn't trust Ebay again. I bought my S5 (after a short time with Developer Edition) on Ebay and it may have had previous damage. The motherboard logic board failed completely finally. Previous to this Ebay phone I had an old flip phone from like 2008 off Ebay. Brought it to Verizon to fix and it fried their system and they gave me a free phone .... found out it had water damage! @blackhawk suggested I buy from fusionelectronix.com (claim new phone) and I was looking into Swappa (mint like new used). I will have to run the firmware numbers by XDA before purchase but I need phone ASAP as my S5 is out.
Oh right and I use JODIN on Mac (same as ODIN) will it work with the newer Galaxies? I was able to flash pit / zip files no problem on S5 previously.
I am unlocked and rooted.
I use ODIN V3.14.1_modded on Windows to flash my s20+, no idea if JODIN works on newer Samsung phones.
It's completely understandable about being gunshy with eBay. If the retailer you posted allows easy returns, no reason not to try them if you wish.

How do I get the PIT file and firmware file for S20+ SM-986UI? I will need it for JODIN. I'm reading online and research shows I can use something called Samloader?
If I must use windows to use ODIN I can try to find a copy of it and setup in Virtual Box like I did previous to JODIN.
If there is a warranty on the new phone can it be returned to stock?
I emailed the company i'm interested in buying from so waiting to hear back.

Question S21 FE 5G Custom Rom

Hi guys!
I bought a S21 FE 5G and noticed that it seems to let you unlock the bootloader, apparently unlike other Samsung phones? However I have not found a single tutorial on how to install a custom rom on the phone. From what I read there is a TWRP for the phone so I would guess that it should at least be possible to flash some GSI images. Is this correct or is there some reason why there are no GSI instructions for the phone even a year after the phone launched? Maybe some Samsung specific issues?
Any insights are appreciated.

The Treble Check App I used tells me that my Device isnt Supported, but another says that it is.
I used some GSIs on my Device (PE+ and Evolution X) so it is possible.
