How do i know if the bootloader is unlocked? - Essential Phone Questions & Answers

i just recently bought this phone off from a friend's family member , it had oreo beta 2 installed and i updated it to orea beta 3. ive seen posts that says if u have oreo beta it means u have the bootloader unlock. just wanna double confirm

If it's unlocked you'll get a message telling you so whenever you boot the phone.

If you updated it to the Oreo Beta 3 OTA then your bootloader is locked. OTA updates won't work otherwise

That's not exactly accurate.
An unlocked bootloader does not prevent an OTA. If you are rooted the OTA won't work.
An unlocked bootloader has nothing to do with it.

Also, I havent tested with this device but usually with other phones
fastboot oem device-info
Tells if the device is unlocked.
Otherwise you could try the command
fastboot flashing unlock
If the phone prompts you with a confirmation if you really want to unlock the bootloader, then I am guessing it isn't.

Just boot to the bootloader to check.
With the device of hold down the power and volume down together.
Also on a reboot if the screen says it's not secure then it also means it's unlocked

Three UK and bootloader status

Is anyone on the Three network in the UK and have tried rooting or ROMming their phone??
I have been trying for a week now to access the bootloader (using 'adb reboot-bootloader') so i can use fastboot but the phone just restarts and boots up like normal. This to me suggests a locked bootloader.
After several calls to Three and an official complaint made, they insist the bootloader is unlocked yet when i went to the Three store the other day they say it is locked. Someone is lying!
Can anyone else on Three confirm if its locked or not??
All i want is to boot temporarily into TWRP and create a nandroid backup. Ive done this at work plenty of times yet I cannot do it on my own phone!! :/
You need to set the OEM lock to off in developer mode.

I have set OEM Unlock and USB debugging and still no joy.
Someone at Samsung told me my phone is locked but Three still claim its not locked.
I have been able to get ODIN to see the phone but i cant risk flashing anything as Samsung have told me they wont repair my phone if i do.
All i want to do is boot the phone with a temporary recovery. For that i need fastboot but i cant get fastboot no matter what i do. Its should be so simple!

How to unlock the bootloader with nougat build?

You can get your unlock code from the Motorola website: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
As the website mentions, this will void the rest of your warranty once your device is unlocked, though there are reports on XDA of people getting their devices serviced even after a bootloader unlock. Your experience may vary.
Also, I'd recommend toggling OEM unlock on - you can get to this by going into Settings > About Phone, and tapping 7 times on the build number section. Go back to the main Settings menu and you should see Developer Options has appeared. Go into the Developer Options and scroll to OEM unlocking, and toggle it on before you boot to unlock your bootloader.
So the method would be:
1 - Toggle OEM unlock in the Developers Options
2 - Follow the Motorola website instructions to unlock your bootloader
3 - Wait whilst it wipes your data
4 - Boot and enjoy your unlocked phone
Good luck!

You need to check your driver to recognize the device. With the command "fastboot devices" there you should see your devices serial number. If not = driver, cable, firewall problem or your device is not in fastboot mode

Bootloader unlocked but Frp locked

So, some months ago I unlocked my bootloader, I just did it because I knew that the huawei bootloader unlock site likes to go down when you need it the most. And now I want to install twrp. But I cant use any fastboot commands in adb. OEM unlock button is off and greyed out in dev options. And since the unlock site is off right now I can't relock it.
Any suggestions?
EDIT 1: Ive just tried removing the google account and the factory resetting with recovery but the OEM but is still greyed out even when no account is associated
In Android 7 (EMUI 5) OEM Unlock is always GREY even if its unlocked.
Do you remember your unlock code?
If yes, just use Service ROM to reset everything including lock your bootloader and then try to Unlock the phone again.
Service ROMs: https://forum.xda-developers.com/p10-lite/help/original-service-rom-huawei-p10-lite-t3688097
If you don't remember your code you can send email to UK support and within 2-3 business days you will receive your unlock code.
Send this to email [email protected]
- Your Full Name
- Phone Model
- IMEI (*#06#)
- Serial Number (*#06# or *#*#1357946#*#*)
- Product ID (*#*#1357946#*#*)

So if "OEM unlocking" is enabled in developers options my bootloader is unlocked? Do I still need to get some unlock code from huawei? My device is WAS-LX3. I'm new to huawei and don't have a clue about this.
Boot into Bootloader and you will see two rows
Phone status (Bootloader status)
FRP status (OEM status in developer menu)
======
Phone Locked/Unlocked/Relocked means that your Bootloader is Locked/Unlocked/Relocked (Relocked means manually locked by you and it's almost the same as Locked which is factory locked)
FRP Lock/Unlock means that OEM status is Disabled/Enabled in developer menu.
======
In oreder to install TWRP you must have status Unlock on both rows.

Hi everybody, I'm unable to unlock my samsung M30s even after following various methods properly, I'm able to go upto bootloader, after which I have to long press vol up button to unlock it but nothing happens at this stage, help please, thank you
Did you enable oem unluck under dev options?

yes i did, still i get stuck half way thru on odin when i was trying to install twrp
So in your bootloader after pressing up(short click not long), on the upper screen does it say Oem lock = true or false?
If it says oem lock = off it sounds like you have to flash vbmeta in AP so you can flash unofficial binaries. Sorry if I can't follow your problem correctly, just trying to figure out if you just failed at some point or if something really is going wrong... This phone should unlock really easily.
Also may I ask which guide you are following?
Edit: Saw your post on the TWRP thread. So it seems your bootloader is unlocked! As long as you can boot to it you are fine, don't worry!
Get your firmware from frija, https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910594/
Make sure you get the right Firmware (Look at your phones box if you still have it, CSC should be at the end of the Model number, also my Box says its a M30FZ even tho it's a M30FN).
After you're back to running firmware and still wanting to install magisk, follow santooshs TWRP thread's install guide.

ROOT SM-T555 Nougat (Android 7.1.1)

Hello...
I am looking for a working way to root my SM-T555
The device is running android 7.1.1;
base ver. "T555XXU1CQHA";
build ver. "NMF26X.T555XXU1CRG1";
Samsung experience 8.5;
Android security patch August 2017.
So far, the several attempts I made using every T55X related software I found in this website have been unsuccessful.
It would seem that the rooting software available is for "Marshmallow only", thus not Nougat specific,
though I read some comments stating that the TWRP made for MM worked on Nougat too and, after that, Magisk would/could do the job...
So I gave it a try but, after installing the recovery, my tablet got stuck every time: refused to boot normally
and if I turned it off, long pressing the power key, I couldn't turn it on again as if it was bricked.
Every time I had to re-start it in download mode and re-flash the original stock rom with Odin in order to have it working again.
On top of that, the "OEM unlock" key is not present in the developer mode list: none of the "date changing tricks" I found around the web seems to fit this model.
I am inclined to believe this "might" be the mother of my problems in rooting the device though, supposedly, the patches were not for Nougat, anyway...
The developer options page, once activated, can only be "turned off" ("greyed out") but cannot be deactivated;
while, on other devices, if you turn it off the page usually disappears after rebooting then you have to tap 7 times the build version, again, in order to make it appear.
I never had problems in rooting any of the phones and tablets I have /had, including an SM-T819 running Nougat 7.1.1,
thanks to the great job done by the coders in this community to whom I would like to express my appreciation for what they do for the benefit of us all.
But this thing seems to reject everything I throw at it and it's been the most stubborn "phone like object" I ever fought with.
So far I am the one loosing the fight... I wish some of you guys could give me the means to defeat it.
Thanks in advance to whoever may be available to help me out.

thanks for your reply.
maybe my post was too long and boring so you didn't read it all
Of course I already tried the solutions posted in the page you suggested but they did not work.
not the autoroot files, not the recovery, etc...
I quote: "after installing the recovery, my tablet got stuck every time: refused to boot normally

If there is a TWRP file specific for my Nougat version available I'd be happy to give it a shot

Did you follow a guide when flashing TWRP? Did you unlock your bootloader?
You need to be clear and concise in your posts as yo what you did and how.

of course I did follow the guide by the book. also, the recovery appears to be installed properly, Odin showing a nice green PASS sign, but it doesn't work anyway
now about unlocking the bootloader, as I mentioned in my first post:
"the "OEM unlock" key is not present in the developer mode list: none of the "date changing tricks" I found around the web seems to fit this model.
I am inclined to believe this "might" be the mother of my problems in rooting the device"
every time I had to re install the system, so there clock want back to zero. Maybe I should be waiting for the allotted number of days to pass on order for the OEM unlock key to appear...
but before my first attempt to root the device, almost one month was past and the OEM unlock key wasn't there, notwithstanding...
I hope there was a chance that the bootloader was already unlocked...
to be concise (schematic):
tablet in download mode
untick auto reboot in Odin
AP loaded with "smt550_cf-autoroot.tar"
flash with Odin, OK, green sign PASS
reboot manually home+volume down+power,
then switch to volume up when screen becomes black
the Samsung logo appears and stays there indefinitely
So I turn the device off, long pressing the power key
then I try and turn on the tablet but does not turn on anymore,
not even pressing the power button for 30 second
then I press home+volume down+power again
to enter download mode and reinstall stock rom
(the same happens with
sm-t550_p550_p555_cf-autoroot.tar
or twrp_3.0.2-1_sm-t550_mm_7816.tar,
I also tried
twrp_3.1.1-1_sm-t355_251117
remark: none of them mentions T555 nougat)

What process did you follow to unlock your bootloader?
Stop trying to use Autoroot. Let's figure out what we need to do to get TWRP on your device. Once we do that, you can flash Magisk in TWRP for root.
Please read this guide, sections 1 through 4 (don't worry about the GSI stuff) and tell me what you have or have not done.
ok, I wasn't able to do this:
Unlock Bootloader
Enable Developer Options and turn on OEM Unlocking
OEM Unlocking is missing in the list, as I mentioned in my previous posts
I tried the date change trick but it didn't work

This is the first step. You cannot flash custom or modified images if the bootloader is locked.
Connect to the Internet and check for updates in system options, then check Developer Options again.
I did that step too, several times:
the system found an update available
the first times I cancelled the download
then I downloaded the update without installing it
then I tried and installed it
no result at all the attempts: the OEM Unlock key does not appear in developer options

it is the first time I work on this specific device, so I couldn't tell: so far I couldn't find the OEM unlock option in the list
it never happened before on any of the several devices I have rooted in my life,
included another Samsung tablet SM-T819 running Nougat 7.1.1: the option was right there and all I had to do is tick it.
I used fastboot for other brands
I wish there was a way to use fastboot to unlock the bootloader on Samsung
if there is any I don't know it
adb is working, but when I give the "adb reboot fastboot" command, the tablet enters the download mode and fastboot does not see the tablet anymore from the computer

Samsung devices do not have a fastboot mode.
Since this is a Snapdragon device, it probably cannot be unlocked, especially if it was marketed in the US.
Only Exynos and international Snapdragon devices can be unlocked, unfortunately.

actually I am in Rome, Italy so I am quite positive it was marketed here...
is there a way to know for sure whether or not it is international?
the Samsung SM-T819 I am writing from has a snapdragon chip
but I had no problem unlocking/rooting it,
I bought both the devices here in Rome
now that's a mystery...

Usually the model number is a good indication with phones - the G908U vs G908N for example, but I don't see that being the case here
Have you tried signing into a Samsung or Google account on the device before checking for updates and looking for OEM Unlocking?

I did that too...
on a freshly installed rom:
I connected the internet thru wireless
signed into my Google account
completed the tablet configuration, etc
then I went and enable the developer options
no OEM Unlocking yet again...

You manually checked for an update too?
Did you try disconnecting from the Internet, disabling network time, and manually setting the time ahead 1 week?
