Galaxy S9+ RMM prenormal state - Samsung Galaxy S9+ Questions & Answers

Hi, i have issue to flash twrp on my galaxy S9+ (to flash a custom rom after) I have read tons of old thread that did not work for my phone (flashing official rom and wait for 168 hours or more, connect to the internet and so on...) none have work so far, even with OEM unlock on!!!
I try to downgrade to android 9 but get a message as it is not allowed from odin.
Is there a way to flash a custom binary to this phone? I have a recent updated android 10 as official rom and get the message RMM state prenormal when trying to flash twrp ("Only official released binaries are allowed to be flashed")
Here the screen capture of information about the version that is installed on my phone (an official rom from sammobile for my country XEF)
I am getting crazzy with all wrong information and wrong tuto that never work for me.
Plz help me or tell me i will never be able to install TWRP on my phone, i need reliable information about what happen really on my phone.
I can't believe that samsung win this war and force us to stay with all this google ads and preventing us from being able to root this smartphone.
Sorry if my english is not perfect, i used this site to find custom rom for so many years now, i can't believe my phone will stay locked for ever.
Thank you for your kindness.
a desperate galaxy S9+ user.

hi , I am also meeting this problem with no working solution. If you have any solution @ me please~

Root My Galaxy A5 (2015)

Hello Guys,
I am new To XDA and recently registered. So I am not sure that I am writing this thread in right place or not. So, please tell me the right place if i am wrong.
Ok, I have Samsung Galaxy A5 (2014)/(2015) (SM-A500G). It came with Android 5.0.2 Lollipop.
As most of you know that few months earlier samsung rolled out the marshmallow upgrade (6.0.1).
I upgraded but my device performance considerably reduces. Even some daily used to tasks start giving too much load to the device. In small words, Device started to hang too many times than earlier.
And some of you may suggest the reasons like:- Nearly complete storage, Power Saving, Too much apps, Virus and malware etc.
(Samsung Help Center Suggested it). But i can assure you this is not the reason. My storage is almost 70% free. etc etc.
The real reason is MARSHMALLOW UPGRADE.
So, I think the best way to solve it is Rooting.
But I am an newbie to the world of rooting. I don't know what is custom recovery, TWRP, Odin, CF-Autoroot etc.
I only heard there names but nothing else.
This doesn't mean that I know nothing about how android works and what is custom ROMs. I can manage these things; but not the above mentioned.
So please anyone of you can tell a detailed guide how to root galaxy A5 (2014) on marshmallow 6.0.1 with all the steps mentioned
and what each steps do. It will be very helpful.
And few things more, 1] I am thinking that after rooting I reinstall the official Marshmallow ROM; as earlier I updated my phone by OTA update and so might it cannot get to it's full potential. I am not sure that this method will work or not, so please clarify this point also.
2] My only source of Internet Connection is the device itself by making hotspot. So please please guys, give me a fully tested crash proof way to do rooting. I don't want to brick my device ( No one wants but in this case if it happens I can't find some way on the internet to reverse it). And you can also suggest any before hand precautions like full Backup of current system image etc etc. that will help if something goes wrong.
3] I already read a few threads on XDA about this issue but I cannot understand properly, so please don't provide links to these threads.
4] Also please provide a list of official and unofficial ROMs for A5
Thanks in advance
I have to read some pages to find a good tutorial but I'll find one. I root Samsung phones all the time. Its not going to brick your device. Asking here was smart, don't trust any website you find off google without fully understanding. Also, you can not install stock ROMs from custom recovery, only from a computer. That process is easy. Download the firmware and flash it. The other choice is custom ROM and recovery. Let me know what option you want to go with and I'll explain more. There are good custom ROMs, ressurection remix. Lineage os. Ice, tipsy is a good one. I use RR on my S5 and s7

Thanks for reply. I really appreciate it.
I read your reply but can't understand it fully. The reason is simple- I currently don't know what is Custom recovery and Flashing. Please explain these terms first and then I will tell what way I want.
Thanks.
A custom recovery allows you to flash zip files and operating systems from your phone directly, but only custom operating systems, not the official Samsung firmware. It is safe to use. Flashing stock firmware is the operating system as Samsung released it with nothing changed. You can gain root access to your device on stock or custom. Usually custom removes the carrier and Samsung stuff that takes up phone memory. It depends on what you want to use your phone for.
OK I go for samsung stock (official) ROM
Flashing is installing the contents of the package to your phone with a special tool like Odin or a custom recovery. And recovery is the menu on your phone from which you can restore backups or flash files.

Create an account on this site, it is free. Locate firmware 5.1.1 for your device, and make sure it is the same as your cellular service provider. So if you are on AT&T download a5 5.1.1 AT&T firmware file. It will be a large file. Once you have the file you will need a computer application named Odin. I will post a link for it shortly.
Hey wait a second. there's 6.0.1 or 5.0.2 files present. no 5.1.1.
Sorry, I replied too late. Actually caught in busy work.
Ok, I googled to know more about rooting etc. etc.
And I got a few uderstanding.
Then I re-read your replies and fully understood them.
Then something came to my mind:-
I am currently on 6.0.1 and Want to re-install it. So I currently downloaded 6.0.1 firmware from sammobile.
So, I don't know Odin can reinstall firmwares or not.
Just for your knowledge. See If we are going right or not.
Thanks
Hey, Anyone out there, please help me.

need help disabling FRP and other download mode security things on SM-J120A

im attempting to "upgrade" my Samsung galaxy express 3 J120A with cyanogen mod (i forgot the new name) buti cant get the twrp bootloader on becuase of some security issue, and i cant find any way to disable it. i've looked at other forums with no luck, and the express 3 is harder to find because no one develops for it.
Samsung SM-J120A AT&T
Well I was able to obtain root with this phone with the firmware J120AUCS3AQE1 using the Kingroot and SuperSUME PRO APKS. Although that is as far as you can go with this phone, the bootloader from what I have gathered is locked as well as signed by AT&T making it unlockable. So flashing a custom recovery and custom ROMS on at least the AT&T version is no good. I couldn't find this firmware anywhere online for free so here is the link to the google drive that you can now download and use at your leisure. Good Luck for what could have been a nice phone for custom ROMS it's officially a dud.

Is Samsung Galaxy S7 Edge SM-G935T unrootable/unmoddable?

Sorry in advance if this is common knowledge. Semi-noob. I searched forums far and wide for past 3 days for this info.
Device: Samsung Galaxy S7 Edge SM-G935T (Snapdragon)
I have the latest Samsung/T-Mobile firmware installed (July 2019 update) with Binary 10.
In a nutshell:
From what I have gathered, Samsung Galaxy S7 Edge (T-Mobile) has a locked boot loader, which means that it CANNOT be rooted or modded (at this time). Is this entirely correct?
In detail:
I switched my phone service from T-Mobile to Safelink with the same phone and ported phone number. The warranty is expired, and I accept the risks. I want to get rid of T-Mobile bloatware on my unrooted device, and even install custom ROMs so that I can experiment with the possibility of better WiFi signal strength and other fun stuff. My phone is great, but it does not run as smoothly or fast as I would like it to.
Tutorial after tutorial has resulted in dead ends (SW Check Fail using Odin and download mode, Heimdall, etc.). The main issue seems to be that the binaries cannot be older than what I currently have installed, and I have the latest one, Binary 10.
It is my understanding that this cannot be navigated, unless I get off my butt and figure out how to exploit it myself. Is this correct?
If not, is there any way to get around this locked boot loader issue with the SM-G935T having the latest stock firmware (Binary 10)?
You guys rock.
Tap
I swear to god I've been strugling for solid 1 hour just to find a proper firmware binary 10 just like you. But it seems like worthless. If you find anything please help me *sob*
did you find the solution yet? cz am in the same situation right now, my phone is running on the latest binary 10 like you said...

Galaxy S21 (Exynos) Rooting and custom ROMs

Last time I tried rooting was in 2016/2017 using Super SU but now many years later I want to try to root my phone again. I have Galaxy S21 ( Exynos ) and I was wondering what would be the easiest way that won't cause too much trouble.
What are the pros and cons of rooting a phone in 2021 and are there any dealbreakers like not being able to recieve system updates or banking apps not working at all.
I would also like to know if there are any android 10 based custom ROM's for Galaxy S21 currently?

In order to root you need to unlock your bootloader, which means no system updates. Most apps will still work if you install Magisk (SuperSU equivalent). There are not really any roms yet, but you can see that easily from the rom section of this forum:

Hi,
Since there's no custom ROM for this model, I wanted to try the GSI way.
I've installed TWRP on my S21 (o1s) following this procedure : https://forum.xda-developers.com/t/...-for-galaxy-s21-exynos.4241869/#post-84592059
Then, I flashed /e/ OS from here : https://images.ecloud.global/dev/treble_arm64_bvN/
However, the phone keeps bootlooping after displaying "This phone is not running Samsung's official software. You may have problems with features or security, and you won't be able to install software updates."
I believe I'm missing a step in my installation (something about vbmeta maybe ?). Can anyone help me ? It's my first time dealing with recent Samsung phones (= post-Galaxy S9).
(I've also posted this question here : https://github.com/phhusson/treble_experimentations/issues/2006)
