Samsung Galaxy S10 [SM-G973F/DS] | How to flash Android 10 instead of Android 12 - Samsung Galaxy S10 Questions & Answers

Hello everyone,
Have Samsung Galaxy S10 [SM-G973F] for 2 years, being very satisfied. It came with One UI 2.5 | Android 10 | G973FXXS9DTI8.
I did not upgrade, staying on the version as it came. Android 10 performs well for me.
Recently bought another one, a Dual SIM version ... Galaxy S10 [SM-G973F/DS]. This one came however with preinstalled One UI 4.1 | Android 12 | G973FXXUFHVE1.
I want to get the second one on the same version of the Android 10.
Checked with CPU-Z the specs, both are on the same Exynos CPU, both devices have the same Release date 01.03.2019.
From reading forums / tutorials / guides etc. for some days now I am aware, that it is not the easiest thing I want to achieve, on the other hand my understanding is that it is doable.
I am looking for a senior well experienced advisor for this task.
I am also aware, that the risk is at the end still on my side.
Some fair remuneration for such support is to be expected.
Feel free to reply here or PM me, whatever is the preference.
Looking forward for your support / feedback.

You will not downgrade the original firmware version in Samsung because of the BIT.

Lowering the stock firmware version locks the bootloader. There is no chance to lower the bootloader version to be able to flash official android 10 when the phone had firmware with higher BIT than that of android 10.
You can try to get rid of the official firmware and flash hadesRom Q Stock v2.0 for Exynos with consistency as described in the thread:
knox related features won't work (Samsung Pay, Pass, Secure Folder etc.)
However, it is not known whether this is possible, as neither the author of the thread nor anyone else has answered the question on this issue.

will the note5 get official or unofficial android 8

does anybody know, will note5 (N920X) get android 8
Um? Look at when this phone was released when it comes to official updates.
Then look at how many active devs there are for this phone. So no and no.

G977B latest firmware currently, and potential One UI 3.0?

Hi, I haven't checked in here much since I first got my phone and followed the guides to update & root etc. It seems fairly quiet in here, guess it wasn't one of the massively popular phones.
My phone is currently running this firmware, but am I able to install newer versions from this list, which all match my phone's BTU code? (Also is there a best guide for updating a rooted phone?)
The other thing is the One UI 3.0 update, the old announcements mention S10 series phones getting it, and specifically include the S10 5G. All the recent beta files that have been made available and announced release dates for the official release version mention the other S10 models but not the 5G. Any ideas, anyone heard anything? Anyone officially signed up for betas and know they actually exist?
Cheers!

note 8 snapdragon lineage os help

its been a few years since i modded a phone. i recently got my hands on a used samsung galaxy note 8 {factory unlocked/no carrier} with a snapdragon processor.
model # SM-N950U1
Im searching around this forum but most of the info is for exynos processors.
i need to unlock the bootloader and root so that i can install
LineageOS 19.1.​how can i do this?
The snapdragon version is called the "greatqlte". You can root it via twrp, but I'm not sure about custom rom support, and definitely not lineage19.1.
The snapdragon version has basically no support on xda. Someone posted a question similar to yours a while back.
too bad , its still a good phone, whats the highest version of android i can install ?
I don't think there are any roms.. I think I saw an oreo one, but you're probably better off sticking to oneui on android 9, which is stable (unlike the oreo build).
You can still root and debloat/customise your phone via magisk modules etc.

Android 8 Downgrade ROM for Note 9?

Hello,
I would really like to get Samsung experience Oreo 8 on my Note 9.
I am aware of binary versions and that a simple software flash is not possible.
But in the S9 community i saw this:
[ROM] [S9+] Downgrade S9+ to Android 8.0.0 [G965FXXU1ARB3]
It's common knowledge that if Samsung releases an update, it will make the performance of our cellphones slow and the quality of the camera drops drastically, you miss the performance and quality of your camera back to the way it was when you...
forum.xda-developers.com
It's a stock android 8.0 custom rom for the phone, allowing for a downgrade even with a newer binary.
So, is something like this avaliable for the Note 9?

Stock Rom or Custom Rom?

Hey there. i have a s20 fe 5g (snapdragon, model SM-G781B), galaxy s8 (exynos), ans galaxy tab A 7.0 2016. Right now I managed to install Android 13 (Lineage OS 20 + NikGapps + Magisk for safetynet) on my backup s8 aswell I managed to flash Lineage os 14 (Android 7, along with Gapps) on my galaxy tab A. Im wondering to do the same about my S20 FE 5G since its support is unfortunately about to end. Thought of flashing TurboUI after i would unlock my device but just want to confirm its safe before doing so. What you guys think? Many thanks.

Hello
This will depend on what use you will give it.
Apparently you are not interested in any of the OneUi customization layer, nor Samsung Dex.
Personally, I am not interested in lineageOS or any rom that is not based on OneUi.
well with many errors, be fighting with incompatibility.
you will find GSI, Lineageos, etc.
I preferred stock rom with modified kernel, androd 13 will not stop working in 2023,2024,2025, etc.
I don't see the importance of moving to an invented and beta system for the team, at least at present.
You will find among the best options:
*stock,root,kernel(bandit,klimbo,etc)
*Turboui v4
*GSI.

Rn my S20 FE 5G is at binary 5. I dont care about rollbacking because i do like the latest verisons and have no use to move onto earlier versions. I just wonder if binary 5 would only limit me to this android 13 one ui 5.1 (like if i couldnt install an android 13 or even a future android 14 rom only because of binary 5). Would it be safe to switch to a custom rom that has the same patch and the same android version without binary 5 doing mess there (like i want to install the latest turboUI at one ui 5.1 may patch, is that possible?)
Rn the device is at may security update, I hope it solved this problem so I could safely move to custom rom without further issues. If I had screwed please let me know as possible to I could reconsider before doing so avoiding further damage. And yeah I have checked OEM unlock and it appears so i believe no issues should occur, just should factory reset (among with removing samsung and google accounts before doing so), enable debugging and oem unlock, go to download mode and then unlock bootloader, and then flash twrp and then whatever i think so.
And yeah I prefer one UI over stock android however the latest custom one ui version for s8 was only one ui 2.5 (hades rom) and no one even dares to make a new one for it, is just dead there. I felt urged to install android 13 so i had no choice but to flash LineageOS 20 (along with nikgapps and magisk). Meanwhile the S9 can get even one ui 5.1 ported via noble rom. I wish something would be done despite being 3 years already since.
But still I won't have prob flashing kernels instead of custom roms if so. Thank you very much.
Alright, just managed to install TurboUI without issues and against all odds.
I was worried because the new binary would mess there but still I managed to do it without issues, and I feel grateful for it
Speechless.
I can't appeal your urges to desperately switch roms.
reading the previous thing you wrote, I have nothing more to say.
If you have errors in the future, please go to the appropriate channels, (turboui, gsi tem, etc.)
Thus, avoid publications due to user errors without investigating before installing.
excellent day.

Alright, have to admit, learnt the hard way
there is SEVERE lack of custom roms there. The lineage OS cant mix with gapps and the custom one ui rom drains battery faster. I had no choice to revert to stock rom. I downloaded its firmware of april patch. Flashed it using Odin and it worked successfully!
You can call me an idiot for the rest of my life as you wish, i had should considered before doing so. Anyways I feel grateful for restoring its rom. But anyways if I would need safetynet I would welcome myself to do so.
I should learn more before installing these stupid roms. Maybe i will continue flashing on S8 but i wont longer flash on S20 FE since that incident. (And noice, the software firmware not matching, aka red message on bot disappear!)
If you have any suggestions youre welcome to tell me so, sorry for not beliving you at first. I should owe you everything
Have a nice night, ig, and I should learn much from that
I understand your inspiration to improve performance.
I've been doing this from symbian (nokia, sony ericcson, palm, blackberry, ios)
current times are not the same.
we are with more powerful processors.
larger and faster ram memories.
Over the years it took me to understand that it is currently not necessary to change the rom.
Example: you are with a s20 FE android 13, it is a completely current system, recently released last December.
I would not have to go to lineageOs, why?
Why did android 14 come out for lineageOs?
I'll have to break down my s20, of course not.
Seeking to get the most out of Oneui with a kernel that exploits its characteristics and without system bugs, seems to me to be a more suitable option.
When it is 2026 or 2027 see GSI options would be a good option.
repeat again, it is a personal thought, for so long I learned, to free myself from stress and constant mistakes.

Alright, just finished relocking my bootloader. Yeah, no more software updates but I can still download them online, and they are security updates so i guess not really a big loss because no more OS updates (One ui 5.1 is final!). Still I HAVE to learn from this incident onwards, maybe on 3 years whenever the device would be too old like the s8 only then i would reconsider doing so. But for now I would stay with this stock rom and I would keep updating it time to time as needed. Everyone makes mistakes anyways. And yeah bank apps continue to work despite device not being play certified, so I guess no root and safetynet would be required. Still, Im very sorry for now trusting you, and I would from now reconsider what Im doing. Lets hope it wont happen even again, peace
Edit: Also managed to get OTA updates and play certification back after relocking it, noice, updating to may patch shortly after recovering my data

I understand
my team is a:
G781B Oneui 5.1 patch February binary 4.
I'm in stock, recovery, no encryption, root, kernel Klimbo or bandit.
I am more than satisfied.
a kernel that delivers power, overclock, etc.
For games it is plenty, for daily use it is wonderful.
Sorry if my previous translation sounds harsh.
Only that I currently install several roms, kernels, graphic drivers, etc.
they only cause bugs.
If you are looking for something stable I recommend stock and what I mention.
greetings.
In banking matters, there are modules for magisk, they worked for me.

Yeah as I relocked my bootloader play certification and ota updates came back
No longer trusting those BS roms, only losers would do so. That rom has drained me much battery and only let me charge at 3W (Yeah I have charger with display, and this occured in real life!)?! What a BS rom tbh! The only positive point I managed to find was the Google feed, but who would burn their battery away just for google feed?! After reflashing stock rom much better!
Very important thing to consider if you even think about flashing a custom rom on your S20 FE 5G. DONT DO IT, YOU WOULD REGRET IT SHORTLY.
I have unlocked bootloader and OEM root.
Even so, I get updates that obviously I will not update.
The last strong update was 5.1 in February. We will not have 6.0, there is no point in updating.
I can go back from android 13 to 12 and 11. Is it necessary? No, but I have the option.
greetings.

In the end security updates should protect us from any kind of exploits, including dangerous ones
But as the devices continues to discontinue (I mean, from october 2023 will start Quarterly updates and year later fully discontinued, the point would of course rise again. But until this happens the custom roms have a chance to delelop as time is going, and if there wont be atleast 1 GOOD custom rom, whats the point to attempt to flash a human managed ROM just to later report bugs to them, impacting your daily basis and ect?
After the last security update on about 2024 I believe custom roms would have chance to rise again, just like it was with the S8. S8 ROMs are better than the S20 FE 5G's ones. I need this time to let the custom roms develop, and once they are developed enough I would reconsider on installing one.
Until then, good luck

I understand you.
The people who have the time to try the roms are appreciated and they are the ones who help the development.
in 2018 i had s9 snapdragon 845.
I was on oneui 2.5 android 10.
in your case you acquired s9 exynos. a jewel to know that note 10 lite would carry android 12 and 13.
They gave me an A7 2017, said note 10 lite managed to port oneui 2.5 android 10 (official was in 8.0 oreo)
I'm assuming your s9 runs android 13.
only that samsung Dex and iris lose or am I wrong?
Anyway, for day-to-day use, having the s9 with android 13 is great.
Yes, the roms for the s8 will be better, because the years have passed and the project is more mature.

I never had a s9 but I have a s8. The only problem with the S8 was that its latest One UI Rom is only maxed at One Ui 2.5 (Android 10, Hades ROM). Thats the only main one UI port available. You want to upgrade software? flash lineageOS then! Pretty dissapointing S8 only supports One UI 2.5 max meanwhile S9 supports one ui 5 max. And note 10 lite doesnt have as many custom roms as the S9. So just like the s8 got locked at one ui 2.5, the s9 would also lock at one ui 5? and after getting locked would the s9 users be forced to install stock android, just like on the case of the S8 users which the same happened to them earlier?

In the case of the s8 it is to be in 2.5 with android 10.
is a candidate for lineageos or gsi.
the exynos s9 will have up to oneui 5.1 ported from note 10 lite.
remember that originally it would be in 2.5 android 10.
you can still live with the s9 with note lite size on android13.
or at best go to s20 fe
Alright, an update after a while
Managed to successfully resolve the issue with Samsung health not working: I have installed a patched version and it's working like new. Just to note I shouldn't update it in any case. The only question is if it would sync with the watch. I mean it already can sync with the account, but I would to test it with the watch too. If everything is going fine I have no prob returning to Samsung. The fact I even didn't had to root to install modules only to patch this issue was wonderfull.
About secure folder and Samsung pass I don't care anymore about them and I had barely used them too, and I have no issue leaving them alone. Instead of secure folder I can use Google photo's safe to store my naughty photos, and about Samsung pass I can use Google passwords instead. Galaxy wearable has worked from day 1 since the issue no matter the incident.
This is a big lesson for my ass, and I shall be smart before doing naughty things like this again. Kids, please learn from me and don't be a stupid guy like me.
