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?

Question Fido Canada S22 Can't OEM Unlock. Any solution, or which alternative model to get?

Hey guys,
Haven't kept up with research on phone unlocks etc etc. I love having my phone unlocked for the true night light, youtube vanced, perma ad block across phone and other such things.
Which version of the S22 should I be going for right now to get so that I can root my phone completely? Would the Amazon Canada version work (‎SM-S901WZKEXAC)?
Here are the specs/details of my Fido S22 phone that just came in, that DOESN'T have OEM Unlock option on it, not sure if this clarifies anything!
Model : SM - S901W
Snapdragon 8 Gen 1
CPU : sm8450
Baseband : S901WVLU1AVCJ
Build Number : SP1A.210812.016.S901WVLU1AVCJ

@newuxtreme any luck with unlocking your bootloader? I have the same model from Rogers and no oem unlock option in developer settings.
Did Amazon build work?

No US or Canadian Models have an unlockable bootloader by default. Id suggest getting the gobal model
SM-S901B

the OEM lock is now hidden on the S22 and I believe on most newer samsungs as well. in my case I followed a dictation on the internet and it worked well

S22 s901u if you search oem, it comes up as oem unlocking under developer options

Could you provide more info on how you were able to oem unlock. I have SM - S901W and the oem unlock shows in setting search bar but NOT in the dev options itself. Please help

S901u same here. Shows up in search that oem unlocking in settings is in developer options, so the phone says. It is hidden and needs to be enabled so you can unlock this

Really hoping there is a solution here... I got this phone because Samsung offers oem unlocking and it would be a shame if I cant unlock the bootloader

There is no oem unlock on North American devices. The s22 wasn't capable of being flashed by token. You all are out of luck for now
The s22 cannot be bootloader unlocked. Only method was by flashing token and I don't believe te s22 was included in this.

Oem unlocking must not be removed but hidden or disabled, because if it was removed it would not show up in search and then say it's under developer options. So you must be incorrect.

@TheMadScientist is correct - Snapdragon devices are generally not bootloader unlockable.
The OEM Unlocking toggle is hidden because ro.oem_unlock_supported and sys.oem_unlock_allowed are both set to 0 at firmware build time and cannot be changed except via remote firmware update.

Question unlock bootloader? SM-S901U1

Hello is there any way to unlock bootloader on U1 ? theres no oem unlock in options ( changing date doesnt work )
phone is from us ( XAA ) version.
any tool ? any guide ?

No US models can have the bootloader unlocked as of now, i think. Since the S7 it's been nearly impossible for U.S. models to unlock, the S8 was unlocked only since an engineer leaked some data.
So if you want to root your SOL, might need to get an international unlocked version.

S22 s901u snapdragon USA search for oem in settings and this shows up as a setting in developer options. Is there a way to enable or unhide this setting? Because my phone thinks that it is there or something...

You are not entirely correct. We have unlocked bootloader on us devices. But his s22 I'm sure is to far updated to be able to do anything.

Oem unlock does not exist on us devices. And if you have even had it update one time it is not possible to do

[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.
