Hi everyone,
I want to root my new Galaxy S9 (SM-G960U1) with Snapdragon. I read lots of topics about that. Some people says it's impossible since Snapdragon bootloader is locked. But there are some topics about unlocking Snapdragon.
First of all, I cannot see OEM Unlock option when I open developer options. I also tried to change date to 1 month ago, turn of auto updates and restart the phone for RMM state. However I don't know which state the phone is either prenormal or normal. But nothing is changed, I still cannot see OEM Unlock.
When I switch to download mode, there is no info about RMM state. Following lines are written;
FRP LOCK: OFF
KG STATUS: Checking
WARRANTY VOID: 0x0
QUALCOMM SECUREBOOT: ENABLE
RP SWREV: B7 (2,2,2,7,2) K7 S7
SECURE DOWNLOAD: ENABLE
I'm doing all things while the device connected to wi-fi. But, I didn't insert my sim card. Is there a connection between sim card and RMM state? Should I wait 7 days to see OEM unlock option?
Thanks in advance for your help

U1 isn't rootable. The only snapdragon version that is rootable is the international sm-g9600. Bootloader is locked on all US variants. So the instructions you're trying to follow will never work.

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.

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?

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.
Hello I have been trying to RMM Unlock using Chimera and it keeps failing. I have tried the seven day trick in addition to using Chimera with no luck. I also tried KnoxGuard Unlock using Chimera and it failed as well. Please let me know if you can offer any assistance.
Edit: In download mode no RMM state appears and KG state is checking. Therefore I think OEM Unlock button should appear. But I still think the bootloader is locked because I could not successfully flash a combination AP into my device. I guess there is really no way around these features?
Edit2: I reflashed again and its now says KG state is prenormal. This probably has something to do with the fact i didn't reset factory settings before flashing. Anyways, KG state is prenormal and Chimera KG Unlock does not work.

After reflashed the ROM, connect your phone to internet and wait a few minutes to prevent KG State status to be Prenormal. For A50 there is no RMM state but KG State.
So lately, I tried to unlock bootloader of my Samsung Galaxy M30 with One UI Core 2.0. As I had read in many guides that after successful unlock, the option of unlocking OEM will be grayed out. But when I enabled it, it asked for my device PIN, then Samsung account password and switched off automatically. After factory reset, it booted up but the OEM unlock option was still blue and togglable. It read Bootloader already unlocked!
I'm confused because there was no 'device lock' mode in download mode, no need to 'long press power up to unlock Bootloader in download mode' or 'no gray toggles'.
On Download Mode I could see "OEM lock: OFF" . Does it mean that my Bootloader is unlock.

You are bootloader unlocked. Check the guides on this forum, and also the TWRP thread.

hello everyone

with latest modem and bootloader which is G960FXXUHFVB4
security patch 1 march 2022
developer option is = ON
OEM UNLOCKING = ON (Bootloader already unlocked)
USB DEBUGGING = ON
*in Download mode
RMM STATE = PRENORMAL
KG STATE = CHECKING....
FRP LOCK = OFF
OEM LOCK = OFF
the question is , i can't install twrp. how ?
error : "Only Official binaries are allowed to be flashed".
i've been looking to google page 2 but no solution
1. from changing the date trick,
2. using miracle box to baypass the rmm
none of them works,
i still can't install twrp, error : "Only Official binaries are allowed to be flashed"
if there's anyone who can solve my problem, i owe you my thanks.
I don't know if it applied to the S9, but most recent Samsung phones have a very particular way of fully unlocking the bootloader as such
How to unlock bootloader:
- Backup all your media, this process will delete your internal media including music and photos
- Go to developer settings and enable [OEM Unlock]
- Reboot to download mode
- When prompted, press and hold VOL + to enter bootloader unlock mode
- Press VOL + to confirm you want to unlock bootloader, this will wipe your data
- If you think the bootloader is fully unlocked, it is actually not! Samsung introduced VaultKeeper, meaning the bootloader will still reject any unofficial partitions before VaultKeeper explicitly allows it.
- Go through the initial setup. Skip through all the steps since data will be wiped again later when we flash TWRP and magisk
- Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader. This step is MANDATORY
- Your bootloader now accepts unofficial images in download mode.

Yeah it looks like the guide really covered their bases. Check download mode and check unlock mode to see if it asks you to unlock (and not lock) the device.
I've had Samsung devices in the past that required this step more than once since the first time it still gave me the option to unlock instead of locking, which means that it didn't really unlock in the first place.
Has anybody solved this issue?
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.
