There is no "eng bootloader" that will boot on your device. There has not been an "eng bootloader" in circulation that is actually bootable on all devices since the s7, and there won't be another one. What Samsung calls "eng mode" nowadays requires a special custom certificate tailored to your specific device's imei and DID numbers, of which the DID is non transferrable identifier. In short, you don't have one and therefore there is no way to get around your locked bootloader. It actually does not involve replacing your bootloader anyway. It's simply a signed certificate that grants your device more freedom with any Samsung bootloader.

Now, please let's not continue with off topic discussions polluting this thread, which is clear in what devices it supports

Have you even bothered to read the thread you posted in? Hahaha. Yeah, the Latin American Snapdragon can be rooted. You are in a thread dedicated to rooting that Snapdragon model, where the files are posted as well as accounts of people's success. Also, there is a whole Snapdragon section for the S9 and S9+ where TWRP and even an AOSP ROM is posted. Soo, you may be wrong my friend.

To clarify though, only the SM-G9600 and SM-G9650 models of the Snapdragon Varient can be rooted. The US models cannot be rooted.

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] rmyc:
why is this happening.

i'm doing everything , phone setups fine with root and everything. when it restarts,this happens?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
Please do a little research. This is the RMM status prenormal that is discussed at length in this thread and every other root/unlock thread for these devices. You need to wait up to 7d with all updates applied for oem unlock to reappear and you can then flash TWRP again following the directions EXACTLY to prevent it from happening again
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] rmyc:
This is after waiting 7 days, getting oem unlock. Successfully running crom. Installing the twrp and associated files and rooting the phone. I'm confused what steps I'm missing.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Teracotta:
You made a mistake somewhere, maybe didn't flash no-verity or the RMM disable.

Because "Only official released binaries are allowed to be flashed" means that you flashed custom firmware and the phone rolled back to RMM status: Prenormal

I don't think we have access the no-verity or rmm disable scripts anymore. I believe you have to use the travis kernel ver1.2 which does these functions now.

After you flash twrp you have to immediatly boot to twrp and flash the kernel and wipe data otherwise you will get rmm prenornal again and I believe also lose your unlocked bootloader status

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
Yes you need twrp to get root, and you need root to install magisk.

Also, if you're going to root, why wouldn't you install twrp? It's way better than stock recovery

I bought my phone used. If I can run CROM and it says the device is unlocked but I don't see OEM Unlock in developer settings does it mean the previous owner did the OEM Unlock themselves and I'm good to flash?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
No. It means (provided your phone is a 9650 you are under RMM lock. Make sure you have no pending ota updates, and wait 7 days and it should appear. Once it appears you will be safe to flasb
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ledhed:
I do have an OTA update that keeps popping up but I keep clicking "later". When OEM Unlock appears and you swipe it doesn't it wipe your device right away? I thought CROM only works if your device is OEM unlocked? What should I do?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
You need to apply the update or your own unlock won't appear. This has happened to a few people (including myself once) if you search the thread
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ledhed:
I just had the OEM show up even with the update pending. Do I switch it on, it'll wipe the device then I run CROM again and follow all the steps in the first post?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
No, do not wipe or anything first, you could reset the clock.

as it says in the op:

1. Run crom (only have to do this once ever, no need to repeat even if you full wipe

1. Oem Unlock.

2. Reboot DIRECTLY to download mode

3.

UNCHECK AUTO REBOOT

in Odin and Flash TWRP in download mode using it

4. Reboot DIRECTLY into recovery from download mode

5. In TWRP, flash the RMM removal zip

If you mess up step #4, you will wind up back in RMM jail for 7d. This is why you want to uncheck auto reboot in Odin because you don't want to miss it.

As it says above, running crom to unlock is a "once per device" action, if you did it before you can delete it, you won't ever have to do it again.

Let me know if you have difficulties doing this.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] ledhed:
Thanks very much for your help! I'll lose the zip files I need to flash after factory reset, right?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
You have them stored on your internal storage, and the oem unlock does in fact trigger a reset, then yes. I personally back everything up and copy all zips onto an external sdcard that I make regular use of, primarily to avoid issues like this.

As for the forced factory reset, I don't know why it makes some do an immediate factory reset sometimes and doesn't otherwise, I just know that at least the last time I went through this i was not forced to rest. You are doing the right thing though by assuming it will happen and planning accordingly. That way if it does you won't lose stuff, but if it doesn't then that's just a bonus ?

False. There are tons of roms that run great. You are just looking in the wrong place.

Head over to the Treble forum. Any of the new style GSI images will work on the 9650. This is where all the rom development happens now, since one port can be run on numerous devices now

I have an S9+ Qualcomm International (Open China), and I'd like to flash it to change CSC to XAA U1 unlocked, but I've been told that I can't do this because the Open China 9650 model number is not the same as the US 965F model. As near as I can tell the specs on the Open China vs US models are the same except for cellular bands supported, but my Open China phone is working fine with my provider T-Mobile here in the US.

Is there a way to accomplish what I want to do above using TWRP (or otherwise)? I'd like to keep my unlocked status and not use a carrier specific ROM.

Thx, Gus
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
Maybe. You can definitely install the csc for the us phones but I don't know if something is different on the China ones in the modem binary which we don't have access to modify (I've tried, it throws a security check failed) so it might not be enough. But considering that you are already getting a signal I guess they aren't really that different after all. There were reports during the s8 days that China supposedly used completely different lte technology than the West, so like literally no signal would work. Just another reminder to take everything you read here with a grain of salt lol.

I assume you are talking about the 965U, since the 965F is only outside of the USA. You might not be able to flash it direct from the firmware via Odin, so let me put together a zip that will flash it for you via twrp
