Question S21 Ultra SM-G998B - Samsung Galaxy S21 Ultra

Dear Friend,
I am having issue with S21 Ultra which i purchase just 2 months ago.
I decide to make my device root able , then i have notice that there is no OEM Lock option (Missing) in developer mode.
After searching XDA forum and Google all the setups mention there i have tried to visible OEM Unlocker option but OEM lock option never visible. Even flash stock rom again and again and wait for 168H but still its not visible.
When i go in download mode and try to flash TWRP or any custom rom it show below mention msg.
"Cause
No sign info: (Recovery)
Custom Binary (Recovery) due to remaining installment balance"
Can any one guide me what is the issue, i had purchase this product with Full payment then why it is behaving so strange.

Can you boot the phone? Try fastboot oem device-info to check what state od BL is.

I think you need to have a SIM card in there and to have internet access to see the OEM unlock toggle. Do both of these things apply to you?

Try disabling the automatic date and time and set the date to a day at least one week from now

I have observe a very strange thing, when ever I reboot the device and visit develope option Oem Locker appear then again revisit to developer option it disappear again. Only rebooting device option bring oem option just for few minutes.

so then, when you see unlock option reboot right to DL mode and look if you see device unlock

"Cause

Someone suggested to use Samsung combination file, after searching on google there are only 3 Combination files available U1, U2, U3.
Latest file available is COMBINATION_FAC_FAR0_G998BXXU3AUD3
( I think this not usable on Android 12 version (U4)
Please suggest what option i have left to resolve above mention issue.

Could you try to flash latest Stock rom(Via odin) and try again?

Latest Firmware (SM-G998B_BTU_G998BXXU4CVC4) Flash via Odin...Result same

OEM Toggle is shown but can't be toggled; phone unable to go into download mode.

Hello XDA, I hope that you could help me troubleshoot my Note 8 (N950F).
So it's been 7 days and oem unlock toggle has finally appeared.. The only issue is it is greyed out and unselectable.
When I got this device I wasn't able to see developer options by pressing build number (though I got the notification that it was enabled), I was only able to access the setting by downloading an app short cut for it via the play store and on initial launch it said developer options are disabled. But then second launch it worked. Idk if this is significant but maybe the country this is meant for disabled it? Regardless of the sim card being in/out the phone, it is still greyed out. Also, I was able to factory reset the phone through the settings after downloading an OTA (I did this in hopes of developer options being enabled about a week ago.)
I tried to boot into download mode but it seems I can't boot into it (following the steps only lead to a normal reboot, and when I select that option from the stock recovery or through adb, it only boots the phone up normally. I purchased the phone off of swappa, in brand new/like new condition. Any ideas? Thank you for your help.
Edit: added screenshots.
SM-N950F / DS here running Taiwan software BRI and I have the option maybe if you flash this firmware you'll get it.

Thanks for the answer! However, I don't think I can flash firmware because I can not go into download mode, which is needed for odin to flash firmware

Exactly. That's why I'm so concerned.
Have you logout your Samsung Account and Google account?sorry for my poor English.:crying:
Do you use any of the KNOX stuff? Did you do any factory reset?
Can you "clear data" on "settings" app? this would make the "developer option" menu hidden again. Then re-show it by tapping build number numerous time again. Hoping that OEM is now editable.
Hi, could you solve this problem? My Note 8 has the same problem and I have not found any solution :llorando:.
I would appreciate it if you can help me.

[Exynos] Questions concering OEM Unlock

-This is probably going to be confusing and a bit all over the place, bear with me.-
So, I bought my N8 back in November and directly went in to the dev options and saw OEM Unlock was available.
Now I didn't bother with it and now recently I've been thinking about rooting it, the catch is I've seen countless threads claiming a notorious "RMM"-lock taking place and putting devices in to "Jail".
Here's the sketchy bit:
- I rebooted and checked in DL-Mode and saw no particular line referencing RMM. Then after some reading got buildprop editor and checked what the "ro.security.vaultkeeper.feature" status was; It's 1.
- Rebooted again, double checked and no RMM entry.
- Enabled OEM Unlock and rebooted about 3-6 times (no flashing done) and it booted up fine with the OEM Unlock setting still enabled and present.
- DL Mode still does NOT show any RMM message or line, just "OEM lock" and "FRP lock" are off.
Am I missing some information as to how the "Jail" is triggered or does flashing only trigger the "Jail"?
BTW, here's info on my device:
- N950F, unlocked, Germany
- On latest January Patch, N950FXXU3BRA2
- Non-branded, but marked as DBT

You unlock the toggle and flash twrp, etc., then when you boot back up you must ensure the i.e. unlock is toggled on (or else toggle it). Otherwise you'll end up in jail when you reboot again, since you flashed custom and didn't unlock OEM before the new reboot.
This question could have been asked in the oem unlock thread too

Alright, I'll check that and see if i'm also in the boat.
Odd enough that it toggles itself off automaticallly, that is wondering me.

Yep, just as I suspected; Your idea didn't apply @sefrcoko .
I installed TWRP, Magisk, the no-dmverity (in that order) and booted perfectly fine with the following result:
- Dev options were hidden since DATA was formatted
- After opening Dev options the OEM Unlock was still switched on.
That has me thinking if it is either sw or hw related, that some devices lock-up.

You asked what jail was, and I explained it... You're just not in jail. Not every device is affected, and fixes to prevent the issue are being baked into custom roms and .zips now too. Lots of factors at play, hence the monster OEM Unlock thread . RMM seems to be the culprit.

If the workaround to bring back the oem unlock toggle isn't working, then you will have to wait the 7 days for it to appear. Then you can toggle it and try installing twrp again. You likely missed a step in the process last time which resulted in 'jail'.

Reboots don't affect the 7 day timer. Your uptime timer will reset, but the 7 day timer for OEM unlock is server-side.

I'm not sure but I think that installing the update could restart the 7-day wait period. If you want to root as fast as possible then it's probably safer to not install the update for now and just wait for the OEM Unlock toggle to appear. There is also a stick thread here with a workaround to skip the 7 day waiting period, but it didn't seem to work for everyone (although it did work for me the one time I tried it).
Any luck///need help too.
Any luck with getting the OEM to show?
I've tried them all waiting 7 to 2 weeks, factory reset change date at setting up insert sim card and no luck. I got my note 8 at soon as it came out so maybe it has something to do with it? I want to root it so bad it cant because of no OEM. Any new information would be great!

Damn, sorry I thought I listed it. I have a t mobile note 8 where the OEM wont show up and a unlocked note 9 N9600 where the OEM is grayed out to which I tried Odin flashing N9600 CPT/TCP version (not to sure right early this moment) and the flash passed but the phone was exactly the same without any changes and still the OEM was grayed out. I tried 3 different methods of changing dates on both phones with no luck. Any kind of new information or version ti they and get this OEM to work for me would be greatly appreciated.

Ok the T-Mobile model has a locked bootloader that can't be unlocked, so OEM unlock won't work.
The N9600's bootloader can be unlocked though. I have tried the date trick in the past on another Note 8 variant and it worked, but I have since read different things such as recent firmware updates stopping the trick, or needing to jump more than 30 days ahead instead of 7 to make it work. Not sure if all that's true or not, but if nothing works then I would probably back things up, flash original firmware through Odin with full wipe and wait 7 days to see if OEM unlock appears.

Yes I know the t mobile bootloader cant be unlocked but still can get be rooted and use some mods with the lost of 20% battery lose but one has to get OEM unlocked under developers options (that option never shows up for me) I've tried 7 to 14 day without reboot but not 30. I've give that a try on the note 8.
As for the note 9 N9600, I thought it came unlocked already but still just need the OEM unlock switched, which for me is grayed out and cant be switched. I'll use factory reset on both and try the 30 days trick instead of 7 and see if itll work.
Thanks for the info.

Yeah the samfail method for u.s. snapdragon models was patched by Samsung at one point, but it depends on which version bootloader you currently have installed if I recall correctly. Check through the samfail thread for more info there. I have an exynos, so can't say for sure about n9600 but that's what I would try at this point

I cant do anything without figuring out how to get OEM unlock to show up on my note and OEM unlock option greyed out removed from my note 9. The only step one found was the tricking the device on changing the date and that didnt work on the note 8 (going to try it for 30 plus days and see if thatll work) as for the note 9,,,,,,, I dont know why it's even grayed out.

Like I said you won't get it on the T-Mobile model (and iirc it's not needed for samfail, even if you are on the proper bootloader, etc.), but you can always check the 9600 and/or OEM unlock threads for more on that one if the stock flash/wipe and waiting period approach isn't preferred or doesn't work out.

N950F bootloader issue

For mentioned model i do not get any type of Bootloader interface detected as hardware in device menager. Which also means i can not access it from adb in order to unlock bootloader. I have found some talk about switching into Unlock mode from Odin mode but can not find a way to do it. This also happens while i did USB debbiging and OEM unlock set on. I have latest Pie on it if that makes any difference.
I hope anyone has some advice on how to solve this and that you in advance

That's probably because of some recent locks Samsung has made. It used to be easier with Samsung . But anyway, look here for more details. https://forum.xda-developers.com/sa...w-to/guide-root-install-twrp-samsung-t3747535

General What not to do with China ROM

I recently got the phone and i have the China version 12/256. Here are few things to take care:
1) Install Google Keyboard first before debloating system apps using adb.
2) Very Important: First update the phone to latest firmware (12.0.13) before you toggle the OEM Unlocking option in developer settings. If you dont update first and have the option toggled and try to install an OTA update the phone will just bootloop unless you clear the data and sign in with mi account again. This will reset the 168 hours time in the software. So always update the phone to latest update.
3) If you are using google pay, go to nfc settings and change the wallet from Mi Wallet to HCE Wallet.
4) The stock TPU cover is loose on the sides. I dont know if its just mine. But better buy another case from aliexpress.
5) DO NOT install global stock rom through fastboot or mi flash tool. It just wont work because of the different versions(regional) of phone. Only install xiaomi.eu ROM using the guide from a post on xda because the install script knows which version your phone is and installs the appropriate system files.
@ingbrzy can you confirm that? :

It is safe to install. haven't installed it yet but read on forums that it is working.
so I guess
1) unbox your phone
2)update to latest software via settings.
3)factory reset device after that.
3)request bootloader unlock.
4) after 7 days, unlock your bootloader and tooggle that OEM unlock
5)follow instructions on xiaomiEU rom.
is that safe enough? Lmao

6) Find EDL support near you

My friend doesn’t matter how long it takes to boot up.....as long as you not in fastboot after restart
It seems to be working fine but I need to go outside and test the 5G and 4G signals are still as good as before
It's definitely feels much lighter and smoother
WhatsApp notifications are working properly
There's much less apps in the drawer, Chinese was very bloated , now there's not a Chinese app or character to be found!
Also banking apps are working fine!

Please post the instruction how u did it. With full info
Just downloaded and install it from a Windows laptop
You have to wait 168 hours to unlock it and then open the phone in Chinese language to get to the developer options again before you flash , you need to enable usb debugging again!!!
You will need wi-fi to get back in because there's a security check after unlock, it maybe in Chinese but you will figure it out
I had never used a Xiaomi phone before this one , there are literally no downsides anymore....
I'll update if I can find something that doesn't work

Can you explain the technical reason and the source of the information when you claim that you must update to 12.0.13 before toggling OEM unlock.
I started my unlock last week and I have 12 hours left. 12.0.13 was not out last week. So, obviously I toggled it before that.
Can you explain why 12.0.13 specifically is required before toggling OEM unlock?

Because my phone went into bootloop. I updated to 12.0.10 and then toggled the OEM Unlocking. While i was waiting for 168 hours, i got 12.0.13 OTA update and i tried installing it. Phone restarted 3-4 times and took me to recovery. I then wiped data and it started again with a factory reset. So iam just warning people to get the latest update before doing this. Also, i do own a POCO F2 Pro and i am quite experienced with flashing ROMS. Developers always ask you to update to latest firmware before flashing as the new ROMs are based on latest firmware.
Xiaomi.eu is not a custom AOSP ROM but just a word of caution.
Sounds like after OTA 12.0.13 phone should be a factory reset it

The toggle is nonsense
I toggled mine on and off a few times yesterday waiting for update 12.0.13 when I was on 12.0.10
It still unlocked like a charm today
