OEM unlocking and flashing TWRP on a SM-G96W Canada Snapdragon variant - Samsung Galaxy S9 Questions & Answers

I would first like to know if there is still a bypass to the 7 day waiting period to OEM unlock.
And 2 I would like to know if there is a way to flash TWRP and if not, is there a way I can root my phone and THEN flash TWRP with the TWRP app?
I found some rooting guides but they require me to flash a file to my phone which I obviously can't do rn as my bootloader is still OEM locked obviously.
Any help would be appreciated
Thanks in advance!

[Q] unlock bootloader logo

I will receive my galaxy nexus few hours later and plan to unlock my phone. Is there a way to hide the unlock logo after I unlock the bootloader or Can I unlock the bootloader, then root the phone and relock the bootloader after to clear the logo but still get the root access. If yes, then how to relock the bootloader?
fastboot oem lock will re-lock the bootloader
But will I still get the root access of my phone after I relock the bootloader and will the unlock logo disappear when boot up after I relock the bootloader?
p.s. It is retail version
why do you need it locked?
I don't like the unlock logo at bootup and the warranty detail only state that I will lost the warranty if I unlock the bootloader, so relock it in case I need warranty, it may cheat them
so then you relock it if you need to. Development for this phone is very young right now so you'll likely be doing alot of flashing. I flash different rom/kernel combinations probably 3-5 times a day with how often things are updating right now. Besides the little unlock symbol is pretty awesome
I know the development is young, that's why I post this. I just need to confirm
1) Is it possible to relock the bootloader in retail version
2) Will the unlock logo disappear after relock
3) Will the phone can still get the root access after relock the bootloader
Thx very much and please reply me if anyone know!!

1) Yes, "fastboot oem lock"
2) Yes
3) Yes, while "fastboot oem lock" does not touch any of your data, "fastboot oem unlock WILL delete all your data. None of these processes can remove root access, the only way to remove it is to reflash the system partition, either by flashing it manually or through an OTA update.

[Q] at&t bootloader

Googling and searching this website have yielded nothing useful so I figured I'd ask:
Has anyone yet been able to unlock the bootloader on the sm-t807a (the AT&T model of the 805)?
Thanks in advance. I'm just itching debloat this sucker and see what it can really do.
Not yet.
Okay; further query. Does the locked bootloader just mean I'll trip knox if I flash a custom ROM or otherwise acquire root or is it more insidious than that? Because I'll trade my warranty for root any day of the week. Is there absolutely nothing I can do? I can live with just root and not being able to use a custom ROM but I don't know how long I can run this thing without xposed before I lose my mind.
Locked bootloader means nothing will flash unless it stock and signed. There's chance of a brick and/ or end up with Knox tripped just for the he'll of of it.
Has anyone gained any ground on the T-807A as far as unlocking the bootloader. All I can get into is Odin Mode. Is there a fastboot mode? I have two tablets that are locked up and unbootable because of unapproved software. (TWRPn recovery on both occasions)​

[Q] Can I root without unlock the bootloader or to locked it again?

Hello guys, sorry because may be this is the 50th time someone ask this question but the situation change every day. Yesterday I won from lottery and decide to go from G3 to G4. My model is European H815, I want to ask you can I root G4, change the recovery and e.t.c. without unlocking the bootloader? And also if I unlocked it is their any way to locked it again or to use my warranty? Thank you!!
well you can only root using low effort root(google it or find it here ) But to change recovery you have to unlock bootloader
No there is no way confirmed to relock your bootloader
GOOD LUCK
Thank you! If I root by this way and download Flashify and try to change recover what will happen ? Thank you!
without bootloader unlocked nothing will chnage ( recovery wont be installed ) and when you reboot your phone it will get u error (authentication error #9) as i remember and you will have to flash new firmware using lg flash tool 2014 so i dont recommend you do so
if u wanna change recovery unlock ur bootloader
you are welcome anytime
I did not get it, I hope you can light me up:
1. Doing root using low effort root means rooting without unlocking bootloader? (because I flew over the thread and did not read anything about it)
2. If I do unlock Marshmallow's bootloader, what happens when I downgrade to Lollipop via flashing proper KDZ? (I would guess that the unlocked bootlader will be overwritten!? So flashing Marshmallow again would end up in a locked bootloader, doesn't it?)
thanks
You can root lollipop without unlocking bootloader but with marshmalow you can't, you have to unlock the bootloader.
You need an unlocked bootloader for custom recovery.
Bootloader unlocking is a one way operation , you can't go back.

sofrbrick/bootloop

Hi all,
I am new to this forum, but have some experience with rooting and custom roms(oneplus one and samsung)
Now with the Mi Max 3, which was unlocked, i have flashed the recovery twrp-3.2.3-0-nitrogen.img, but I did not realize that
i had to reboot into this recovery from the fastboot mode.
so I endet up with a locked bootloader and bottloop and am not able to unlock the bootloader again.
I think my only solution is the test-point method and a EDL authorized account.
Some help would be greatly appreciated.
thanks
Henry
You don't have to boot into the bootloader from fastboot mode, you can press the power button and volume up button like on almost all other Android phones to boot into TWRP recovery. Sometimes it takes a few attempts to get right, but you should learn how to do it eventually.
Unfortunately it sounds like you had one of the dodgy re-sold Chinese models that had been re-flashed with Global firmware and it's locked your bootloader again on reboot.
Your only option is to use the official Miui Flash tool to boot into fastboot mode, flash the latest Global Developer ROM, and then sign in with your account and apply to unlock the bootloader again using the Miui unlock program. It may be instant but, they'll probably make you wait 720 hours, as the entire point of the program was to stop phones like yours being re-sold outside China.
At least you'll have a usable, non-bricked device though.
Thanks for your answer.
now I have opened the backcover (yes was much work ( I succeded without destroying something) and could apply the test point method to get into the lde mode.
Win10 shows it as qualcomxx at com 3
what is the best way now to awake it to life again? even without unlocking.
hi,
with the test point method I could flash the chinese rom, and the mi max 3 is awaken to life again!
The bootloader is still locked.
I have applied for unlocking, but have to wait some 15 days.
One tip: if the case is open, one can apply a little bit of silicon grease to the small pins on the side of the plastic frame
before closing it. Opening it again is much easier then.
One question: if I replace the recovery.img of the chinese rom with a TWRP image (renamed to recovery.img)
and flash that modified rom with the test point method, could this probaly work?
With a working TWRP one could install other roms without unlocking bootloader.
If yes, which TWRP would you apply?
Thanks

Flashing a recovery should not lock your bootloader, so I don't know how you did it. Note, that if you are using Xiaomi's firmware tool, you should not forget about unticking the box to lock the bootloader. But I would suggest to stay away from that tool and go command line instead with fastboot.
If you can access fastboot, I'd recommend to flash an official fastboot tgz ROM of your choice. Official ROM should boot even with an unlocked bootloader and you may start all over again more carefully.
So I think you might be able to avoid using EDL mode at this stage.
probally I forgot to untick that box. The bootloader is locked and I have to wait 319 hours.
I have got to love the test point EDL method which is simple and effective, and gave me control over the device again.
If I flash again the chinese fastboot rom (in which I have changed the original recovery.img into TWRP.img, named recovery.img) via the EDL
will that give me an installt TWRP (still with locked bootloader, but possible to install custom roms) or will i have a brick again?
thanks

Only you can answer that question by trying it out. Are you sure you have to wait for the unlocking again? Double check that! As I know you also need a priviliged xiaomi account to be able to resurrect a device in EDL mode.

Root with Magisk 22 - Is it possible also on this phone?

Hi all
I know that, at the moment, there is no way to unlock bootloader (is it correct?) on Oppo A52, but is there a way to use Magisk 22 new root technique to root it?
I see that in the Developer Options there is an OEM Unlock option and I have activate it, but I don't see anything different...
Thanks for any suggestions or explanations.

If that toggle moved, typically that means your bootloader can be unlocked. This is normally done through fastboot commands like "fastboot oem unlock" but it's different for some phones and I don't have this one. Hopefully someone here will chime in soon.

There is no way.
Oppo Phones are not Unlockable!
that means: no unlock = no root
Is there a danger of breaking the device by following these instructions?
