S9 Exynos - Rooting issue - only official released binaries are allowed to be flashed

Hi All,
Happy new year. I had been struggling to root the S9 and getting the following error
"only official released binaries are allowed to be flashed(recovery)" while ODIN flashing of TWRP 3.2.1.1.tar
I tried a few methods mentioned in the forum - Wipe/factory reset->Flash Official firmware-> again TWRP using odin
Also tried OEM unlock option. Still cannot succeed in rooting the phone.
Kindly help me with the files and procedure to root and install stock rom. Thank you all in advance.
Regards,
Raghav

How to make rmm normal?? How long to wait 7 days or 14 days after OEM unlock. Also need to put the sim on the phone or can just leave it ON with wifi connection?

Can't install TWRP due to KG status Prenormal

So as the title says, I am on pie SF4 version, in my download mode it says my RMM status: Prenormal
and KG status: Prenormal. and so when i try to flash anything it says 'only official binaries can be flashed'. How do i solve this? Please I desperately need help. I just don't like using my device without any root/magisk and without twrp i'm stuck.

You need use smart switch then use this link to root and twrp --> https://forum.xda-developers.com/showpost.php?p=79378123&postcount=142

What will i do with smart switch? Using smart switch will reset the KG status?

Did you finish setting up the tablet after you factory reset? During setup KG Status will stay prenormal.

After setting up, my KG state went to 'Checking' but my RMM is still 'Prenormal'. How do i reset that? I can't flash with RMM 'prenormal' right?

No you can't
RMM should go to normal after 7 days. You're probably just gonna have to wait.
Do you have the LTE version?

No the Wifi version T830. So it's okay if KG status is 'Checking'? now i just need to wait for 7 days?

Huh that's strange I have a T830 as well but no RMM State.
After setting up Did you connect to the internet, enable developer options and make sure OEM Unlocking is visible and enabled?
If it doesn't show at first leave and reenter developer options a few times if that doesn't work try restarting. And yes KG Status is supposed to be Checking

I have OEM unlocking enabled but I also have RMM 'prenormal'. Normally, as far as i know from reading the forums, in oreo if RMM was 'prenormal' then OEM unlock option didn't even appear in developer settings, but in pie even if RMM is 'prenormal' OEM unlock still appears but still you can't flash anything unless it returns to 'Normal'.

Thats really strange For me I have no RMM State however OEM Unlocking didn't appear for me until I connected to the internet and restarted. Sorry but I got no idea at this point. You may have to just wait the week out.

According to your device it shows oem unlock l. Which means locked. This device looks to have Knox guard mdm service. Looks to be leased. It is permanently locked until removed from Knox mdm server.

Ohh. Is there any way to solve this?
Will installing official firmwares in Sammobile through Odin help?

Hi, maybe this will help you:
This dude also don't have OEM unlock option (he have s20 ultra G988B) but after change date time its show up. Try it.

His isn't that issue. Look at his download mode info. Bootloader l. Which means locked. Any that can be unlocked display a u I believe. I had this issue on another device. It's all caused by Knox guard and buying subsidized device

Hey, did you solved it? bought SM-G986B with same problem - OEM on (L)

Hey brother have you solved that issue ? I've the same problem too, no OEM unlock option.

Hey,
It will depend on your baseband version if you have a snapdragon S20/S20+/S20U. See the thread below about how it can be done and what baseband/bootloader is required to unlock.
no OEM Unlock toggle in dev options
as stated in the title on my s20 plus (SM-G968W) there is no toggle for OEM Unlock, its been a long time since ive tried to root and from what ive been able to pick up from googling is it may not be supported for my country or cpu manufacturer...

[Q] RMM State check/bypass

Hi i've got a question. I recently purchased the A5 2017 (A520F) secondhand and i want to put a custom rom on it. I have unlocked and flashed tons of phones and tablets in the past so i'm far from a newbee.
My phone has "Bootloader OEM unlock" in dev options.
When i go into odin download mode (vol-, home+power) i dont get any message regarding "RMM state: Prenormal". FRP is unlocked.
Does this mean i'm all set to flash anything without the RMM.zip?
I'm having the latest security patch Jan2020 and Oreo bootloader. Knox is 0x0. Are there any other ways to check RMM state?

Reboot device just to check that OEM unlock is still enabled.

Yes, Bootloader OEM unlock switch is still activated.

Then read a guide like this, there are other workarounds though https://forum.xda-developers.com/t/...e-prenormal-on-oneui-android-pie-9-0.3911862/ but don't flash custom binaries while you don't bypass RMM prenormal status.

Yeah this requires a linux distro so i guess for that method i have to run linux in a VM or dualboot on another partition.
However, it still doesn't explain why i don't have a RMM message. Maybe RMM is gone altogether (not sure if thats possible tho).
Anyway thanks for your replies.

Oh, sorry, I read bad, and nothing about KG?
It means you don't have remote restrictions, even with FRP.
In this case, you are able to flash custom binaries.

No problem bud, happens to the best of us. Nope nothing about KG either. I wil try and flash twrp etc. Worst case i'll flash back official firmware. Thanks for the help!

Solved: There was no RMM/KG on the device at all so i went and flashed TWRP and Rise-Q OneUI 2.5. Everything went smooth as butter.

Good, if it is not present in download screen, then in this device, either RMM/KG are not implemented.

Rmm state prenormal fix

Old solution didn't work for me. Does anyone know how to fix it in 2023?

What was the "old" solution?
Try this:
Boot into system, skip through the setup, connect to WiFi. Go to system settings, enable developer options. OEM Unlocking will not be visible. Force an update check, then go back and check to see if OEM Unlocking became visible. If it has, KG/RMM state should be OK or COMPLETED, and you should be able to flash custom firmware.

Did you try to wait 168 hours?

yes, I tried to wait for months and not only the 168 hrs however nothing seems to be working and it's kinda really frustrating
and all tools not working (like chimera, magic crack or whatever they don't work)
I only wanna flash a custom from (one of my rights as an android user (phone is s9+ exynos )
so please if you know any way I can get this done I'd be really grateful

There is no way to unlock RMM until Samsung fixes their servers because RMM server is down ( https://rmm.samsung.com )
