Need help here!
Bought an XL via eBay. Found that it's been flashed anyhow. And I can't root/flash ROM or even unlock the bootloader.
Now below is the situation:
1. It's a Verizon, XL, 128GB.
2. It's locked. And OEM unlocking in developer options is GREY.
3. It's stuck in Android O (Opp3.170518.006).
4. dePixel8 doesn't work. Every time I entered the commands "adb shell /data/local/tmp/dePixel8", it ended up with an error.
5. Because of 1., I can't flash TWRP or any bootloader.
I've heard of so-called "FRP Unlock Tool". But it seemed only working on 7.1.2 below and is considered risky for 8.0.
Though 8.0_DP3 is 90% perfect for daily use, I still want to take a chance. But the question is HOW?

The only time you could unlock the bootloader on a Verizon Pixel XL was before the operating system updated to Android 7.1.1. Android 7.1.1 was patched so the dePixel8 exploit would no longer work and nobody has found a new way to unlock the bootloader on the Verizon models since then. If you want to downgrade from Android O I think your only option is to deregister your phone from the Android Beta Program. Eventually you will get an OTA that will downgrade your phone back to Nougat but it will also completely wipe your phone including the user data and stored files. You will be starting over from scratch and have to download your user apps again. Unless someone comes up with a new exploit you will not be able to unlock the bootloader or custom flash anything on that phone.
If you wanted to unlock bootloader/flash roms/root etc... you should've come here first to check, then checked with the seller on ebay.
however, your options are:
1) put up with phone in stock (it's really not that bad - which is why development isn't into multiple pages of current roms)
2) sell it and get a google version rather than Verizon
Hi everyone !
Hope I'm not making any double post but I couldn't find any explanation for this very specific situation.
After thorough research it, it seems that most of samsung devices has a secret setting called "OEM unlock" that we have to use to do the first step of rooting the device. In some cases that setting is missing but can be displayed again by some "date settings" tricks or waiting 7 days. In some other cases which seems to be mine, the "OEM unlock" setting is simply removed by probably the carrier of the phone and can't be reinstated.
In that last case which seems to be mine, I can't find any precise information wether we can or we simply can't unlock bootloader by other way and therefore root the phone.
Could anyone enlighten me ?
Thank you very much in advance !

I assume you know that the OEM unlock toggle is in the developer settings? To enable developers settings, tap build number repeatedly until it says you are now a developer. You will need no fancy trick to show it as the lock that hides OEM unlock, only came out in oreo. I don't think carriers disable OEM unlock on Samsung's but I could be wrong. Lastly, if you get it figured out, go over here to the right thread and get it rooted. Good luck! https://forum.xda-developers.com/sa.../how-to-root-twpr-flash-a300fu-a300y-t3494362

Thank you for the answer.
You assume right. I enabled developers settings first, saw that I didn't have OEM unlock option visible, then started to look about this issue. It is quick to see that in many case, even for phone not on OREO (I'm with Marshmallow 6.0.1), this OEM unlock is missing. But based on internet available data, it seems that in most of the case there is a trick to make it visible again. It is a sort of samsung security against thief that hide this option for seven days.
The trick didn't work for me and by looking more I saw that some people seems to be facing the same situation as mine. Some suggest that it is disabled by carrier.
But I couldn't find a solution anywhere for that context.
My question remains.
Here is a more detailed explanation :
from https://www.howtogeek.com/239798/how-to-unlock-your-android-phones-bootloader-the-official-way/
""There are two kinds of phones in this world: Those that let you unlock your bootloader, and those that don’t.
Whether you’re allowed to unlock your bootloader depends on the manufacturer of your phone, the model you have, and even your carrier. Nexus phones are all unlockable by nature, and many phones from Motorola and HTC allow you to unlock your bootloader through a similar process as the Nexus.
Other phones, however–and some carriers–don’t allow you to unlock your bootloader the official way, which means you have to wait for developers to exploit a security vulnerability if you want to root and flash ROMs. If you have one of those phones, this guide will sadly not help you.
The best way to find out which category your phone falls into is to browse its section at XDA Developers. If you have an HTC or Motorola phone, you may be able too research its unlockability on HTC or Motorola’s website. If it doesn’t support unlocking, you’ll have to use an unofficial unlocking or rooting method, which you’ll usually find on the XDA Developers forums.""

The trick didn't work for you because there is no security thing on marshmallow. What carrier are you on if you don't mind telling? Samsung's aren't bootloader unlocked like other phones.

The Galaxy A3 2015 (SM-A300FU) has no OEM unlock as A3 from 2015 don't even have FRP Lock, neither it has RMM state. That means there is no lock which prevents you to flash any custom binaries like TWRP recovery with Odin. You'll only lose access to knox apps/services (because of knox 0x1), rest remains the same.

Hi !
About my device, here are details :
Samsung A300FU
Android 6.0.1
BASEBAND VERSION : A300FUXXU1CPH3
Build number : MMB29M.A300FUXXS1CQD5
Carrier was French company called Bouygues.
About bootloader lock or not, I can see on various website that many samsung are bootloader locked but can be unlocked easily by this OEM unlock option. Sometimes it is missing. Two reasons for that : Security check that is removed after 7 days or apparently permanently removed by carrier or geographic area control.
If i'm in that last case, is there any other solution to unlock the boatloader ?Or the phone is just unrootable. It seems strange to me that some phone are just unrootable.
Thanks again !

If you read @prototype74 's post it explains it quite well. I think your bootloader is already unlocked if I read right.

Hi !
Thank you very much both of you for your help. Indeed there was no OEM unlock.
Many posts talking about OEM unlock existing on that A3 and the fact that I couldn't check if it was locked or not using the two methods advised (with adb or with a special code to dial up on the phone interface) led me to stop at that step to be sure before going on.
It is advises not to root a divise with a bootloader locked to avoid bricking it.
Anyway, trusting your input I did the whole process of rooting and putting a custom rom and it's all great !
Hi everyone, I rooted my s9 exynos a few weeks ago but wasn't happy with a few things so I just did a clean install of android pie & got it all kind of stock again. I was going to spend a bit more time fiddling & re-rooting, question is, do I need to activate the OEM u nlock again & start a fresh or just install twrp? Reason I'm asking is that in developer options below the OEM unlock switch it states "bootloader already unlocked.
I'd rather know either way before I wipe everything for no good reason, thanks in advance
Hello everyone thank you for your time it's been a couple days i'm doing reasearch on how to root my galaxy S9 (canadian) and i'm hitting a wall everytime and some post a far too old to be considered.
So my question is without the OEM unlock option in developper options am i doomed to not being able to root my phone ?
And yes i tried the trick with setting the date manually one month earlier but anyway my phone is more than 1 year old so i'm way past the 7 days delay.
Isn't there a way to unlock it with a computer via USB debugging mode ? ( juste an idea like that i know pretty much nothing)
Any clear answer would be greatly appreciated.
Thank you for your time
OEM Unlock option is pretty much like the gate to unlock your boot loader
if your phone doesn't have the option then that could be cause by some factors like,
- either you can't unlock (I believe there are few versions that factory lock which mean cant be unlocked)
- or you have faied to modify your phone, which you have to wait like 7 days to be able to modify again
That all I know, maybe anyone can correct me if I'm wrong

okay i understand more what OEM does thank so as long as i can't unlock it from the inside no modification can come from the outside
You should read through this thread. It has some options that may interest you. The Canadian SM-G960W S9 is definitely boot loader locked that makes it "normally" not able too install any custom ROMs or boot loaders. The good thing with it is that it doesn't trip KNOX!

I am trying to root my phone but I can't get passed enabling the oem lock because it does show up in my developer settings. Is there a way I can root it without enabling that to open the bootloader. I'm very new at this so if anyone can help much appreciated.

If it's the U.S. variant, long story short is no.
Samsung has been hard locking bootloaders on U.S. variants for years now and you need to unlock bootloader (OEM Unlock) to flash custom binaries (Magisk/root).
It used to be that there was no way of unlocking bootloaders until recently, but it's a paid service
If you are really interested about unlocking your bootloader and you really want and/or need root, you can check this thread out: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/
