To unlock S8+ SM-G9550 bootloader use CROM service
Step 1: Download into your phone CROM.apk [message me for link, I'm new member and can't post URLs...]
Step 2: Install it by accepting from unknown sources
Step 3: Hit unlock and you're DONE!!!

What is this "crom.apk" and if all of the devs here couldn't find a way to unlock the bootloader for the snapdragon variant of our phone why would this work? Seems a little fishy to me.
I am not going to be the first to try it and brick my phone. If others try it and it works then I might try it.
Not calling you a liar, I just know that the devs here worked long and hard and didn't find a way to unlock this bootloader so I am not putting much faith into an .apk file. Sorry.

Well I actually found the CROM solution inside this site look for [[RECOVERY][OFFICIAL] TWRP for Galaxy S8 and S8+ (Snapdragon)] on the #3 posted by Jesec with link I run it on my SM-G9550 and unlock bootloader easily now my real challenge is to successfully root my phone which I believe is the path you're heading too, so far I was able to flash TWRP + dm-verity and force encryption disabler.zip + Magisk and been able to almost fully root it and I'm saying that due that if I activate Google account and shutdown/restart the phone it then get stuck at the Boot screen with a FRP locked message...

So you are saying after you run the crom on the next reboot it gets stuck, or only after you login to your Google account? If it gets locked/stuck at the boot screen then your phone is unusable. I am not trying to be a jerk or be difficult, and I hope you figure this out, but until it is fully usable I am not going to try it. Are you using the S8 or S8 plus?
Good luck figuring it all out.

Well, so I guess I should be more active in the site.
There are two firmwares for the G9550 the Hong Kong and the China, one has the bootlader unlocked and the other doesn't, you just have to install the one that is unlocked in your phone through odin. After that you can install magisk for root. I haven't done the process in Oreo, just Nougat, but I have a rooted S8+ g9550 doing this. Today I might try it in Oreo

I've been searching for a method to root a G9550 (the one I have is from China) for a VERY long time now and I still have practically no idea about anything. All of the Samsung phones I ever had were International models.
EDIT: Yes, I realise that Snapdragons cannot be unlocked, but for some reason I'm still trying to do the impossible. I guess I am not rooting the phone lol ¯\_(ツ)_/¯

SM-S205DL (Straight Talk Model)

Hi all,
I have a Straight Talk Galaxy A20, model SM-S205DL. Will root instructions work for this model? I don't notice an OEM unlock option in the Developer Mode menu, but I can boot in download mode. Thoughts? It's been a while since I tried to install custom firmware.

Okay. Is there a way to do that other than the developer options menu? If the OEM unlock option isn't there, is there some other method?

There is a trick where you change the date to some weeks in the future.

im having the same issue

yea the dev options to show OEM Unlock seems to be gone from Straighttalk/tracfone versions, its even Gone from Download Mode (you dont even SEE the option for long-press vol+ to unlock bootloader)

is there a way to root

Some places claim to be able to change the CID of the phone. Would that help? I imagine once able to load different non-TFN BS firmware on the phone that magic developer option may appear. Or is it a hardware thing and the exynos chip has something to do with it? Not sure how it all works yet. Anyone know what the unlocked us retail model contains?
I'm not smart enough to find out so hopefully someone is and reads this and can chime in regarding all the points...
Me and my arrow...

Question Does anyone know how to root this phone?

I tried this method but it doesn't work?

So, there's absolutely no way to unlock a bootloader if Tmobile requests them to be locked? Can I call Tmobile and ask them to unlock it?

there are paid for services run by people, some of them use this site, where your phones bootloader can be unlocked either remotely or via a one use only token and instructions. not sure about A32 but on Galaxy S series phones it costs about 75 dollars US. search here you should find something, a link to a Telegram group probably.

How are they able to bypass Samsung's lock? I don't think paying is worth it to get unlocked, esp over the internet where it could be a scam.

you can join a telegram group full of people either waiting for or already had their bootloaders unlocked. it is quite pricey but it's not a scam (based on the people I've seen doing it) a moderator here used to do it and people have posted about being happy with the service they got.
if it not via that route there currently isn't any other way to unlock bootloaders for US Samsung phones

Be aware when you update ROM after that.
Later version ROM can lock bootloader again and current token may not unlock again

If anyone gets an unlocked stock rom or a bootloader.img even please post it here, for example I've heard some people have been getting unlocked with T-Mobile. Follow the instructions on how to dump the unlocked bootloader.img here:

Yes. I've used these instructions https://www.naldotech.com/root-samsung-galaxy-a32-magisk/
I've used boot.img to patch, and then flashed with odin, worked as a charm.
Turn on Odin mode - by shutdding down your phone, then holding Volume Up + Down, then long hold Volume Up to unlock bootloader, You might need to reboot afterwards, also factory reset is(will be) a must.
Just shut down after that, redo holding Volume Up + Down, then long hold Volume Up, I cannot remember exactly, but I think after that it was once pressing Volume Down to have proper odin download mode to use patched image.
Select patched magisk image patched from/by boot/recovery.img.lz4 archive.

The SM-A326U does not have the OEM Unlock option in Developer Settings to unlock the bootloader, so unfortunately we are unable to use the method linked.

I had an option, starting with tapping on build name to enable dev tools, enabling it then Vol Up + Vol Down.

Please feel free to verify images taken after root been aquired. (magisk image was patched on unrooted os at the time)
The OEM unlock itself in dev options is not doing complete OEM unlock, until contected to PC while Volume Up + Volume Down is presse
d, then loader gives option to do proper OEM unlock.
You're welcome.

Question How to unlock bootloader?

I just received my Flip3 (SM-F711U1) and would like to unlock my bootloader. However developer options is missing the OEM Unlock option. It's completely missing not just grayed out. I read a few articles about needed to change the system date but none of those guides changed anything. Can someone help?
Also, I attempted to call *#*#7378423*#*# to double checked that it wasn't already unlocked and I got a popup saying "Unabled to process the request."
Thank you.

- about phone
- software information

I have no issue unlocking developer options. As my first post said the OEM Unlock option is missing from dev options.

Have you tried through fastboot? (fastboot oem unlock)

Oh, got you. Sorry!

As far as I'm aware samsung devices don't support fastboot. I did attempt to connect it in case I was wrong but was not able to get fastboot to recognize the device.

You can try directly unlock without ticking the oem unlock. By boot into download mode. The other thing is your device or carrier or country wont allow your flip 3 to be unlock. There last step you can try is clean flash via odin with your latest firmware.

I can get into download mode fine but don't know how to use that to unlock directly. Can you give more details?
I tried a clean flach with my latest firmware but it didn't change anything.
It's a US carrier unlocked version I bought directly from Samsung. CSC of XAA. Currently using a T-Mobile SIM.

If you can boot into download mode there is an instruction just press vol up button and it will prompt do you want to unlock bootloader mine is like that. Im not sure yours since mine is korea version.

They support bootloader unlock. samsung dont support using fastboot unlock or command at all

if you're in North America, Canada etc Qualcomm chips there do not support bootloader unlocking, at least the Samsung one's don't, not sure about other OEMs.

They used to, so there was always a possibility it returned.

I recently read this article on XDA about unlocking the boot loader on the Fold 3 which results in Samsung disabling the camera (WTH?), Is this a thing on the Flip3 too?

My device is rooted. I have always been able to find the OEM unlock option under developer options without any constraints.
My camera is NOT affected. I can still use it without any issues.
I have an European device (SM-F711B).
Hope this helps some of you to track down whether this is a location or carrier based problem.

Hey Redhatter,
Out of topic question, but are you getting Tmobile 5G just fine?

Thank you for sharing, I’ll give it a try

To root a phone's Android unlocking its bootloader is NOT required.
You simply have to add SU binary to Android's filesystem and make this binary executable.

I want to oem unlock bootloader for trwp and roms but I can't find oem unlock in dev settings and tried the video above and a couple of other things I found

You need the Samsung flash tool and the version of android for the phone and su +twep+magisk is optional good luck
Ps. Allways back up everything!

And I'm fixing the Samsung flash tool is PC only correct? My **** got stolen like a few weeks ago so I'm trying to figure out how to do this **** without a computer and it's a pain in the ass pretty much impossible.

I am not trying to flash custom ROM, just to tweak the system kernal settings.
I seen someone mentioned to root w/o the OEM unlocking switch available, all that is needed is to flash the SU binary with Odin.. I haven't tried this yet but I am almost positive Odin for windows doesn't even read the Samsung devices without the bootloader being unlocked.
Anyone care to chime in here? i'd be very appreciative!
Mainly WTF is the OEM unlock switch not available on my device. I actually have 2 of the same devices and both are without the switch.
Also would flashing SU work and do the trick?
Any other useful information you could send my way would be really helpful too.

Maybe who's find how to unlock bootloader on this device after July update?
