Missing OEM Unlock (Yup Another Thread) - Samsung Galaxy S10 Questions & Answers

Hey,
I'm using a Galaxy S10 SM-G973W from Bell Canada. I believe that makes it a Snapdragon? I haven't rooted a phone or installed a custom rom in years so I'm piecing it all together as I go this evening. It has most recent update of Android 11 and the OEM Unlock will not show itself in Developer Options. I've tried the fix involving changing the Date and being on Wifi, and up until April, that seems to have worked for at least one person I found in my search, but it did not for me.
Maybe someone has something encouraging to tell me? lol Or maybe this phone's boot loader is just not unlockable.

Marshmallow MCG24 unlock bootloader root etc?

So I bought the phone just now. Paid quite a lot because they don't exist in my country , but I've wanted it since it got out, and it's in like brand new condition so ehhh, why not I said..
Just checked and phone is on Marshmallow 24.81.5quark_verzion.verzion.enUS
Tried Kingroot and sunshine to at least achieve temproot , they both failed.
What are my options right now here?
Thanks!
No unlock options right now if you are on stock 6.0.1 with a locked bootloader.

Thanks for reply! I guess I'll just live with it. Iphone in motorola's body lol. But for discussions sake, any way to downgrade? I know flashing bootloader triggers the "fuse" but I was succesfull with some weird bootloader downgrades in the past wtih 201M (Japanese softbank version of Razr M) and IS12M (JP KDDI version of Droid Razr).
Only problem is, this phone is way to expensive for me to experiment..

Hmmmm... then you were very lucky because gospel around here is you can never downgrade the Motorola bootloader. If you could downgrade bootloader, then everyone would go back to version where Sunshine worked! First Sunshine worked on Lollipop SU4TL-44 (November 2015), then everyone who procrastinated rushed to take SU4TL-49 (May 2016), hoping it was Marshmallow. Nope, it was just a Verizon "security" update to stop Sunshine from working. They had SIX MONTHS to unlock their bootloader and they didn't do it! Then everyone complained and said if only Sunshine worked on "49", they wouldn't procrastinate anymore. BOOM. A few months later (july 2016) Sunshine found another exploit and it works also on Lollipop "49".
But we are STILL seeing people now taking the Marshmallow OTA (November 2016) without unlocking bootloader first. Not you, you said you bought it with it already installed...
One of the Sunshine team members said he briefly glanced at the 6.0.1 OTA and it might not be impossible to unlock the bootloader. But no promises and no ETA. I don't think this phone is a high priority anymore. This is now a 2-year old phone. Still GREAT, but other newer phones get attention. There's been Sunshine for it since November 2015 and most everyone who wants it has had a chance to get it.

Yeah I read whole how to unlock bootloader thread, from 1st to last page but havent' seen anything marshmallow specific so I opened this topic..
Yeah , I was also surprised, but I spent around 1 month working on it , and it was only working with specific firmwares (fastboot files).
Yeah I wish I checked little more about that issue , I would check phones OS and probably not buy when I see it's MM.. Oh well, no going back now.. Thought that verzion's control freak behavior stopped by the time of droid turbo( used some verzion motorola phones in the past) especially when google bought motorola.
I hope people don't see this phone as outdated, because there is no way it can be called that. Many people including myself figured it like a replacement for nexus , and I think it deserves at least root exploit..
Also asked in Sunshines thread about support for marshmallow , got rather unclear response:
Me:Will there be support for droid turbo on marshmallow? Just purchased the phone, didn't know unlocking bl was possible only on lolli... Thanks
jcase: Known at this point,
EDIT: damn I write yeah a lot lol. P.s if mods want to delete topic because it's useless, feel free. Thanks!
EDIT 2: By checking system updates looks like phone was updates 3 days ago so 1 day before I bought it .. Arrrghhhh!!!
BTW I just remembered, "old" Droid 's ( xt910 ,xt912 etc) bootloader was never ever unlocked , but there was a way around it. Safestrap recovery by Hashcode , which I'm sure you all know about. The project is scraped because dev is busy , but I really wonder if anything like that is possible on droid turbo. I also wonder how does it work exactly and what gets bypassed.
From users standpoint: you installed apk which then installed recovery that "bypassed" locked bootloader and allowed you to install /load custom roms, kernels , radios , root etc.. You could even install more OS's at same time like on another "partitions".
hm...

sorry for keeping this post alive, but i really really miss Safestrap when i had the Moto Droid Razr, you could have up to 4 different ROMs installed and it took minutes to swap between them. Man those were the good ole days haha
Edit: added word droid

I remember being frustrated about never-unlockable bootloader while using safestrap at same tame and then realised, hey wait! What do I need unlocked bootloader anyway , everything works perfect and functionality is even better than on most modded phones (at the time).
Having something like this on droid turbo would make it a perfect phone in my opinion, and for years to come.. Wonder whats the dev's view on droid turbo on that..
Anyway I was playing a little, all within "safe zones" regarding the downgrading . With litlle modding I could flash bootloader.img from QUARK_VERIZON_5.1_SU4TL-49_cid2_subsidy-DEFAULT_CFC.xml.zip and most of partitions related to bootloader I collected from various locations,all from SU4TL but it's obviously not important..
So basically what I can't flash to downgrade is :
gpt.bin
boot.img
system files (system,img_sparsechunk.0 , 1 , 2 etc).. I will investigate more.
Started finally actually using phone , all bloatware can be disabled, so it's actually pretty ok for now. Phone feels awesome ..
Mods , please delete this topic in purpose of cleaning, I'm gonna open 2 topics regarding downgrading experiment and making SBF of new Marshmallow OTA

Galaxy Tab A 8.0 2018 SM-T387V OEM Unlock

Heya,
I just recently got a hold of this tablet a few days ago and looked for a OEM unlock switch, which obviously wasn't there, both because it's a Verizon variant, and because it's a snapdragon variant. I've been researching for awhile and found combo files to unlock the OEM switch for this model, but everybody seems to get this model confused for some reason. I tried flashing one using odin and got a SW REV check failed [Boot]Fused 2 > Binary 1. I'm guessing I need to downgrade this tablet back down to android 8 since I updated it to android 9. Before I do that, I want to see if flashing the old firmware will be a waste of time or not and to see if there is a combo file or ENG boot file I can flash to get OEM or at least root unlocked. Something to get rid of all this Verizon bloatware and get rid of the Verizon boot animation with just a stock one. Hope I get a decently fast response.

theres not really any support for that tablet.. u can flash combo but so ur aware its not possible to downgrade.. u need a newer combo firmware that is same rev as the firmware ur on..
there is no eng firmware from what i can tell.
I've found several sites that have the firmware I need, but they're all locked behind a paywall. They're only like, $3 but I don't feel like entering my card info on these sites. Might just bite the bullet and get me a throwaway card. My baseband version is T387VVRU2BTB2. REV0.4. maybe somebody can find one for free out there. If not, I'll probably just pay the $3 and stop being stingy with my money.

I'm also looking for some firmware to possibly bypass FRP on my SM-T387V. Did you end up fbuying the firmware? Did it work?
I have a sm-t307u and while not the same device I'm unable to flash combo files due to a new token security measure. So, no OEM Unlock, no bootloader unlock, and no combo flashing in ODIN.

Sprint Z3 play unlock for Verizon use.

Ok so what I thought was a unolocked z3 play, was indeed a flashed sprint phone. So when I reset it, I lost the ability to use my verizon sim.
I had just bought it from Amazon and might return it, but it's brand new and if someone can give me a pretty thorough guide I might be able to avoid returning it.
It is a model XT1929-3 type M356A. In the settings it says the device is locked to sprint, and "about phone" says the software variant is Sprint, and the software channel says sprint also. It's one of the phones with call plus on it. It's on Android 9 July 1 2020 patch and the baseband says BECKHAM_NA_CUST
From my reading I would have to flash the ROM to something like USC XT1929-4 or the like with fast boot, correct? How exactly do I do that? I can follow directions very well even without pics(but they are nice), but I don't do command prompt often- this took me forever to "type", but I recently got my two new Fire HD tablets debloated and I have hope I can do this.... I already have the USC BECKHAM rom from lolinet I mentioned above and have enabled dev options and flipped the OEM UNLOCKING switch that says it allows the bootloader to be unlocked, but all this seems a bit daunting, so please help an old guy out.

Newbie question - unlocking / rooting the S20 FE

Hello all,
I have a newbie question - please be patient and point me in the right direction. (And yes I did use Google first).
The question is about rooting the (Canadian) S20 FE 5G.
I understand there are different ways to root - and all require unlocking.
For unlocking there are two sets of instructions
- one instruction says I go into developer settings, select unlock and all is good
- the other instructions advise that one has to pay to have this unlocked (to some guy on Telegram) and the price is pretty expensive.
So which one is it?
I am considering the S20 FE and rooting would be one of the first things -so I would like to know if that comes at an extra cost or not.
Thank you for any pointers!
if you have a Canadian FE and it's firmware is earlier than March (as I understand things) you can ONLY pay via the man on telegram to get it unlocked. if your firmware is after March even that might not work for you.
all Qualcomm phones sold in the US and Canada can't be unlocked via simply toggling OEM unlocking in developer options.
As 3mel said "... all Qualcomm phones sold in the US and Canada can't be unlocked via simply toggling OEM unlocking in developer options"
too many folks just don't get that !!!
As far as paying > some person online- True But ... at this time, there are a few that say they do the S20 FE 5G cheap too. Either via Email or Their App.
All I Do Know, is IF you do this, You will not get any OEM updates, (Seeing how they (samsung) that the S20 FE 5G will see 3 major updates at least, came with 10, we are on 11, and so 12 is coming)
Yes, I see you may not wat to have read that, but, with the Carrier unlocked, and Root, am sure in a short time, we can see many different roms for these Newer Phones...
if you remove root and any custom recovery (usually by just flashing stock over everything) you will start receive OTA updates again.
that's even if the bootloader is still unlocked!!
I doubted this at first but it worked for me. plus updating and reapplying root isn't that hard once you've got a decent idea about what each step is doing and why it needs to be done.

Question Is root even possible on my device?

Hello everyone,
As the title suggests I'd like to know if rooting is even possible on my S21 Ultra (US Variant). I've spent the whole night looking for tutorials, forums or any indication that it can. All of them pointing me to the "OEM Unlock" option that needed to be tooled first. Thing is, my device does not have that option whatsoever. I've messed with the time settings, date settings and everything else I could do in between. Still, no luck. Now, I'm fairly new to rooting. I've rooted many years ago and don't remember it being thus complicated. I found a tutorial which stated the new Canary Build of Magisk supported Android 12. Thing is, I Cannot find a way to unlock the bootloader. So my question is if it's even possible. Because if it isn't, I don't want to continue wasting my time. If it is, can some direct me the right way please. I've attached an a image with my software build.
You'll find OEM unlock in developer options. In settings, go to about phone, then software information, then find build number. Click on this multiple times until you get a message saying developer mode.
Go back to settings, then click developer options, then find OEM toggle.
PS do this at your own risk..
Hey,
Thanks for your response. My device does not have that option at all is what I'm trying to say. Its no where in this menu and I have tried everything imaginable.
Have a search for no oem unlock on google, something about setting date backwards good luck.
Post your phone model and build number. Some US phones cannot be unlocked.
If you haven't updated your device you should be able to unlock the bootloader for a fee.
[Android][UNSAMLOCK] Bootloader Unlock for Samsung US/Canada Devices
This thread is @svetius approved Important notice: Do not update to April 2023 security update (XXXXXXXXXXWCX) or later. Examples: G998USQS6EWCA, N986USQU4HWD1. Samsung has patched the bootloader unlock again on those updates. NOTE: The OneUI...
forum.xda-developers.com
I should delete my prior post... I didn't see the image in the first post. Looks like you have a snapdragon model, already at bootloader rev 5. Cannot be rooted. Also, your phone is from Verizon, so even if it were rev 1 it wouldn't be able to be rooted.
