Hi all,
I've searched and searched but haven't been able to find anyone else with the same issue I have with my S9, so i'm hoping somebody might be able to help me out!
Basically i installed twrp and then installed Lineageos with Odin. But after a while decided i wanted to go back to stock (there were a few things i was missing, dolby atmos, the stock camera, wi-fi calling and google pay.)
I downloaded a stock firmware from updato and installed with Odin. I used the BTU version, although my phone would have come with the XEU version as standard. I used the HOME_CSC (not sure if that is important?)
So now my phone has stock firmware and got an OTA update yesterday. But when i go into dev settings OEM unlock is greyed out and says 'Bootloader is already unlocked' and my phone is also uncertified in the play store and failed safetynet.
So i'm hoping to be able to get my phone back to the boot loader locked state and to get it certified and passing safetynet. I've waited 7 days as some people have suggested, phone was up for 170 hours but OEM unlock is the same and phone is still uncertified. My next thought is to install the XEU firmware and see if that makes any difference, but i'm not convinced it will.
Does anyone have any idea on how i can fix this please??

HOME_CSC does not reset the device, CSC does, chances are some of the root stuff / system modified files are still present causing these problems
Factory reset, if that doesn't work, flash again but use CSC this time

Thanks, I'll try that again later. Any idea whether it matters if i use the XEU or BTU firmware?

Probably won't be able to switch to BTU if you were originally on XEU, BTU is multiCSC and contains XEU so the phone will default to it's original CSC
The firmware will flash fine, but if you check the CSC it will likely still be on XEU unless you managed to change it when you were custom

Yep you're right, it's still XEU. I'll try a factory reset. I'm hoping the OTA update may have fixed a few things.

I did a factory reset, then flashed the stock ROM again and used CSC, but the boot loader is still unlocked. I don't have the option to re-lock it, so seems like maybe you can't
Just in case this helps anyone else, I did a complete reset of the stock ROM using @rifek4 instructions from https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963
But i'm still not able to re-lock the boot loader. So going to leave it now and hope the option comes back after 7 days.

Thanks for replying. Do you think that method would help me to re-lock the boot loader?
When I go to the settings the OEM unlock says "boot loader is already unlocked"
Basically all I want to do is get safety net to pass again, and it seems that having an unlocked boot loader makes it fail.
Just in case this helps anyone else.
I downloaded magisk 16.7 beta, 16.6 caused my OS (lineage 15.1) to crash, but 16.7 was fine. I installed universal safety net fix for magisk, beta version. Installation said it failed, but when I rebooted it had worked!
Safety net now passes, device is certified in play store and Google pay is working fine. As @rifek4 said, bootloader lock has nothing to do with safety net (although I've seen a lot of people claiming it does).
I waited 7 days then disabled oem unlock in the developer option.
DONE.
None of skip wait time method work for me.
Hello all. My 935f came with firmware XSG for United Arabic Emirates but I am in the UK and would like to flash VOD instead. I tried as soon as I got the phone with odin but got some error (don't remember exactly but f.w. 2 expected 1?). Anyways, 7 days have since passed and I have access to OEM unlock. 2 questions:
1) does the firmware (XSG vs VOD) changes anything at all?
2) if so, how could I flash this without losing OEM unlock.
Thanks a lot!
Flashing firmwares doesn't effect OEM unlock and I'll install Vodafone bloat, go for btu if you're in the uk

Hi there.
I've been stuck with RMM State Prenormal on my Galaxy A8 2018 for 3 months, waiting for this to be gone. Nothing to do, after 3 months of uptime, it still there.
Many tricks with time and date hasn't worked anymore, but finally I just success to bypass this s***.
What I've done :
_Install stock rom from original carrier (BOG for me, I were on XEF for deleting bloatwares).
_At boot, do NOT put your Google account and Samsung account, only Wi-Fi and that's all.
_When install wizard is finished, do NOT activate Developpers Options. Go directly at time and date, set it 8 days before after desactivate "Auto time and date".
_Go to System Update. Then untick "auto update" and check for update.
_Reboot.
_Go back to actual time and date, check again for update.
_Only NOW, activate Developpers Options and OEM Unlock should be there.
It worked for me after MANY MANY tricks, attempts, and hopeless. This way given me another luck to root my phone and now I'm done and free with it.
Sorry if my english is sometimes bad. Hoping I've helped some users.
Regards !
Edit : I did it on bootloader V3 (U3BRJ4).
I hope it actually works with other a530f
because I have a530w and a530w doesn't have rmm prenormal in bootloader, I can't really test this
Yup, canadian and some versions of samsung smartphone (Verizon or something else if I don't mistake ?) doesn't have any method to unlock their bootloaders because they are locked by default and forever. But I've posted it for those who have international variant (SM-A530F for me).

no, I mean that Canadian variant of a8 is exactly the opposite of what you said, rmm is always unlocked, so oem unlock is always there
and a8 is the only exynos Samsung device in canada so we're lucky we didn't get any snapdragon version or that would be locked forever
Oh, mea culpa. I thought it was like Galaxy S4 who were totally locked (received one from Canada to France, last year, I were disapointed that is not GT I9500 but SGH I337M).
But the result stay the same, this is for unlocked bootloader that can be "locked" by RMM State ^^

once you downloaded it, extract zip file, then there should be 5 files, dont worry about the HOME_CSC, that leaves us with 4 files, put them in the correct position on odin, AP to AP slot, etc
Hi, I've tried many times with différent BL but nothing To do' OEM doesn't appears and always state Prenormal :/

It's a pity that after root we lose all the guarantees through knox

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.

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...

Hello everyone.
I recently bought a Samsung Galaxy S22 SM-S901B/DS 256MB in the UK. I'm trying to unlock the bootloader to get root with Magisk.
First, I updated the operating system to the latest version available. After that I managed to toggle the OEM unlocking in the Developer Options but when I restart to Download mode I don't get the option to long press the volume up key to finish the process. There's a line that says "OEM UNLOCK: ON(U1)". That very line read "OEM UNLOCK: ON(L1)" before I toggled the option in the Developer section.
I tried to install an AP file modified by Magisk with Odin 3.14 but at the end of the process I get the error "Custom binary (VBMETA) blocked due to remaining installment balance" and I have to flash the original OS from scratch to be able to use the phone again.
Could anyone please help me here?
AFAIK, currently, there is no way!

2. Connect one end of USB to PC
3. Press and hold Vol Up and Down keys simultaneously .. then Connect USB to device.
4. Keep holding the keys until you see BL Unlock menu.
5. Long Press Vol UP
6. Device will auto reboot multiple times and then prompt to Factory reset
7. Complete the Factory Reset and reboot to System
8. Wait few minutes, finish Welcome setup connect WiFi to register OEM unlock.

That's what I get at step 4. No matter how long I press Vol Up + Vol Down, i can't see the option to unlock BL.
Looks like some restrictions for unlocking are enforced by the region specific Firmware.
You can try to flash alternate stock firmware from different region (probably Asia).
This could hard brick your device. So, it is your choice to proceed or stick with current Working Firmware without root.

Do you know of any specific firmware that allows to unlock the bootloader for this specific model?
Can I cross flash a firmware from a different region?
Can I downgrade my firmware?

2. I have not tested cross flashing Samsung Firmware so I cannot give any feedback.
3. Downgrade from A12 to A11 will certainly fail. I have tested this just last month.
> "Custom binary (VBMETA) blocked due to remaining installment balance"
That's seems like another layer of protection by Samsung, so that you first pay off the loan for the phone, and then you can root it.

For my phone model they use a EVR firm, so I downloaded SamFw_FRP_Tool_v3.0 and changed the CSC of the phone to EVR. I downloaded the most recent EVR firm and I tried to flash it with Odin 3.14.1 modified, but I keep getting a Fail message.
No idea what to do next.
