Help getting S9 back to stock. - Samsung Galaxy S9 Questions & Answers

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.

Can you lock the bootloader back?

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.

Google VS. Non-Google Variant Differences

This thread is to gather technical clarification for those of us who have wondered about this:
If a Google phone (e.g. Pixel / Pixel XL) is purchased from another retailer (e.g. Verizon [with a locked bootloader]), other than the physical hardware, are there any technical differences in SOFTWARE and/or CODING that would restrict flashing OEM firmware from Google after the bootloader is unlocked?
***** (Is the Verizon variant restricted from flashing Google firmware?) *****
My apologies if this has been covered in another thread.
So I went ahead and downloaded the latest "7.1.0 (NDE63P, Oct 2016)" file and attempted to flash the "flash-all.bat" file on my Verizon Pixel XL through fastboot and was unsuccessful. Attached is a screenshot of the error.
It hangs at:
"(bootloader) Flashing active slot "_b"
I'm uncertain of what this means but it didn't work. It allowed me to exit and reboot to my current state before the flash. Maybe someone can chime in on this.
I bought Verizon pixel xl from best buy. It is sim unlocked. Bootloader is locked. It can be unlocked via depixel8 sunshine method. I flashed Google stock rom nde63p and rooted. All is working 100 percent.

I too, also have a Verizon variant that is bootloader-unlocked with depixel8. What am doing differently that isn't working to flash the factory image NDE63P?

https://developers.google.com/android/images follow instructions exactly in the link. That's all I did. The toolkit does not work for this. Anymore problems I can assist you tomorrow. Just make sure ur phone is is bootloader mode. Also the image is fully extracted in your adb tools folder.

Set it up on another computer and start from scratch. Windows 10 has some issues.... If it doesn't work and you want it done just get the device to me and I'll do it for u my self. Message me and I'll work it out with u.
My question is somewhat related so I'll post it in here.
If I unlock bootloader with depixel8, then flash the Google factory image and relock bootloader, in theory I should now have a Google version correct? Has and had success with this?
The reason I want to relock is to not trip safety net. Right now I'm enjoying the phone without root, but know I will want to root eventually and don't want to miss the easy conversion to a official Google model.

No. Until you see Jcase or another dev post a full Google Store conversion for the Verizon Pixel, do not relock your bootloader. That is, if you want to root your Verizon Pixel in the future.

Update your adb drivers. You need sdk version 25. Your error, [bootb doesn't exist] is because you are using an older sdk that can't handle all of the new partitions in the Pixels. There was no boot_a or boot_b in Nexus, which is why it doesn't know where to send the files.

Most likely you are trying to flash-all with an older version of the SDK or using another older tool. flash-all only seems to work with the latest SDK or the latest tool. You can flush each of the 14 img files individually as well.

I updated SDK and flash was successful. Can you please help me understand this too: now that the Google Firmware has been flashed, does that "change" the phone from a "Verizon" model to a "Google" model? Also, why is it that in Developer Options, "OEM Unlocking" is still grayed out?

Glad to hear you got it flashed. You answered your own question. Currently there is not a way to convert the Verizon model to the Google model. They are in fact exactly the same in hardware and firmware. Zero difference. The reason that it is grayed out is because when the phone first boots up it checks for a whitelist (or maybe a blacklist) by CID or MEID. If you're phone is listed as a Verizon device, the OEM unlock option is grayed out. That is the way they locked it down. They just grayed out the toggle for the locked phones.
For the time being, the only option you have is to leave the bootloader unlocked. If you lock the bootloader, there is a good chance that it will be permanent after the November security patch. Maybe later someone figures out how to fool the check at first boot (or change the CID...). Or install a custom rom. This would be the only way to turn the device into a "Google" model.

Aside from the option to unlock/relock being greyed out, will unlocking disable the updates? I was reading another article that said if you unlock the Verizon pixel using depixel8, then you would not be able to take OTA updates. Aside from unlocking for custom roms, is there any real need to unlock?

Unlocking will not disable updates. In Developer Options there is a toggle to disable this. Depending on what you do to your phone after bootloader unlock, disabling this might be important to prevent bootloop during an update.
Aside from root, various flashable mods, custom rom, or custom kernel, there is not really a need to unlock. Your phone is certainly less secure by doing so. If you plan to stay completely stock, keep your bootloader locked.

Odin stuck on recovery.img after countless searching no luck help is needed!

my friend rooted his device but stupidly turned off OEM and now his device won't turn on
I tried looking for an international firmware and flashed it on Odin but it got stuck at recovery.img, been like that for an hour,
Is it because OEM is locked? (so is FRP by the way)
Do I have to enable a setting from Odin?
he has an S9+ G965F dual SIM, he bought it from Spain but says its an international model, he doesn't seem to find the country code anywhere on the box
I need help and everything is appreciated, the sooner the better, thanks!
Check in download mode which version Bootloader the phone is running (B:1 or B:2) and match it with the firmware you are flashing, you cannot downgrade the Bootloader
G960FXXU2BRGA <<< Version 2 BL
Fixed!

He managed to fix it himself, I was using Odin with TeamViewer from my computer to his laptop, and I think that messed with something as he repeated the exact same steps after I disconnected and worked flawlessly

Stoping this damn RMM State Prenormal

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 guys,
I recently got a Moto Z2 Force XT1789-05 variant from Brazil which apparently tried to force an update to the pie but it must have been the wrong firmware so it lost imei and wifi.

No. You just need to sign into google on your phone to enable oem unlocking. Might try pairing bluetooth to get a connection if possible. Might try using the lenovo moto smart tool to see if it'll do a rescue on it. With a locked bootloader typically you can only flash official signed firmware that is either the version or newer. Again, depending on what kind of mess you've got there you might not get anything to flash.

no once your boot loader is unlocked you will not be able to do firmware upgrades. while it is possible to trick the phone into thinking everything is normal it will always fail while trying to install the update. i have tried and it never worked. Although once you relock the boot loader even with knox tripped you will start recieving updates normally again.

yes you can downgrade your firmware as long as the bit number is the same. e.g. there is a number ln each firmware's name like U1, U2
these may be found in the middle of the firmware's name. if the firmware you are downgrading to has a lower bit than of the firmware currently installed it will not work. you will have to choose a firmware with the same bit version. thats why always be on the lookout when upgrading to newer firmwares. for me with SM-A325F the highest bit js U2 and most of the resources are for that firmware so im fine.
