Question Oem unlock not appearing - Samsung Galaxy A02s

Somewhere around mid 2020 i decided it would be fun in trying to unlock my phone. I actually almost succeed, the only problem was that i didny have wifi or cellular available, so i reflashed the stock os, locked the bootloader and called it a day. Now i want to try this again, but the oem unlock option is nowhere to be found. I've tried everything, "fastboot oem unlock", "fastboot flashing unlock", changing the date, etc. I clearly remember the "your phone is not running certified software" when i almost got majisk to work, but now I cant even find the oem unlock. I just want to use google pay man...
Information:
Model: SM-A025G
Android version: 12
Product code: SM-A025GZKEORO
I'll give any additional info needed.

Perform a factory reset after removing your SIM. Skip through setup and do not connect to WiFi. Set the time manually, wait a few minutes, then change the date to at least 7 days from now, and wait a few more minutes. The toggle should appear.
However...Since you've unlocked before, maybe you could just see if you're able to unlock the bootloader?

Havent thought about resetting without the sim, good idea!
About the bootloader, if you mean unlocking it in download mode (holding volume up + volume down while plugging in a usb cable) I dont get such option. I can only enter download mode or restart the phone.
I will respond hopefully tomorrow with an update.

When you're in download mode, hold Volume Up until the bootloader unlock warning text appears.

Heres the update:

I have done the factory reset and changed the phone date, and it (of course) didn't work.

In download mode there is no (hold volume up) option, just volume up to continue, volume down to cancel and side key to show barcode. Something that I have noticed different from other download modes is that mine is also translated in (i presume) korean and japanese.
Heres some more information that may be relevant:
In download mode pressing the volume up key to continue shows these in the top left screen:
CURRENT BINARY: Samsung Official
OEM LOCK: ON (U1 )
KG STATUS : PRENORMAL
QUALCOMM SECUREBOOT: ENABLE (CSB)
RP SWREV: S1, T1, R1, A5, P5
RP SWREV: K 5, S 5
SECURE DOWNLOAD: ENABLE

download mode !!

Okay, let's try this again.
When you start download mode and see the options for Volume Up and Volume Down, just hold the Volume Up button. There isn't a prompt because it's "hidden" - unlocking the bootloader is supposed to be deliberate, not something that can be done accidentally.
Continue holding Volume Up until the bootloader unlock prompt appears.

Holding the volume up button no matter for how long will still result into nothing, sadly.

You are able to boot into Download Mode?
Just to be clear, here's the steps:
Disconnect device from USB cable (leave cable plugged into PC) and turn device completely off
Wait about 30 seconds
WITHOUT PRESSING POWER, hold both Volume buttons, and while holding plug in the USB cable from PC
Device should start with a custom OS warning and a prompt. Release all buttons. One of the options should be "Volume up long press: Device unlock mode". If you do not see this option, hit Volume Down to cancel.
If you can, provide photos of the screen.

[Q] confused about locked and hardware locked

Hi guys,
I am still new to this phone and I am trying to read as much as possible. but there is a lot of terminology to absorb. And I definitely want to make sure my phone is OK before the 14-day period when I can exchange it..
So, I unlocked my phone using one of the posted methods on here. i tried it with an AT&T sim card and it works.
Now, I read that there is something like a "hardware lock" which is bad .. because.. I wont be able to root or put rom or update my phone? I tried to go to a recovery mode, but could not, is my phone hardware locked?
Thanks in advance!

Did you do the correct way to recovery?
-Phone off, both volume keys held down
-Hit and hold power button while holding down volume keys
-The word vibrant will come on, and then it will go black again and reboot (still holding down all three buttons)
-When you see the word vibrant THE SECOND TIME let go of the power button but keep the volume keys down until you boot into recovery.
If not, most likely you are hardware locked. I don't have this problem but I think there's threads around for hardware locked users for workarounds and such.
yeah, i did exactly that:
1) power phone off
2) hold both volume buttons
3) hold power button
4) vibrant comes on, wait, vibrant comes on 2nd time
5) release power button, still holding both volume buttons
6) Vibrant starts in a normal way, i do not see anything different, so I assume i am in a regular mode, not recovery mode

Make sure your Vibrant is hardware locked.
If you suspect that it is, you can read this thread HERE.
That will help you get your hardware locked phone working.
Unless you want to go get a new one.
I tied the following ways to test if my phone is hardware locked
1) vol up+ down + power
2) volu up + power
3) vol down + power
Nothing worked How would my phone would be hardware locked? I have not rooted, installed roms, nor apps.. Everything is stock, except that I unlocked the phone. that's all..
And it will be a huge pain to ship the phone back + wait for a new one, which there is no guarantee it wont be hardware locked ..?
Would I be able to install any rom if I am hardware locked? It seems like bionix mod is pretty popular..
Hardware lock is simply a boot loader issue. The phone has software the runs when you turn it out which in turn boots up the operating system. In hardware locked phones, the boot loader is not looking for the key combo to access recovery or download mode. If you go to the link provided, it tells you how to flash your phone to update the boot loader so that it is no longer hardware locked.

Update to MOB30G - Failed and now can't boot?! - Please Help!

Hello All,
I have a completely stock (Not rooted, and bootloader is locked) Nexus 9 (wifi) that will no longer boot after trying to update to the latest security patch (MOB30G).
I received the notification that there was an update available for my Nexus 9 this weekend. It was functioning just fine, so I chose to download an install the update.
I let it do its thing, and some time during the process something went wrong. I came back to see the little android picture with red "!". There were no words or messages with the error picture.
When I rebooted, There was a momentary message that stated that, "Device is corrupt and cannot be trusted..." and "...press the power button to pause boot".
It then goes back to the little android picture with the red exclamation mark and says "No Command".
I am at a total loss at what to do. It was completely stock, never rooted or anything else and I was applying a factory update?
Please help!
-Jason
@Jsunn Try side-loading the OTA update again from recovery.
Instructions can be found here.
If that doesn't work, try side-loading the Android N OTA instead.
I just had to deal with this after the May OTA. My device was locked and ADB was not enabled but I was able to sideload the dev preview of Android N.
I used the info at this link: Search "Reset your Nexus device to factory settings"
Specifically these steps:
Option 2: Reset device in Recovery mode
If you can't open the Settings app because of device issues, you can use Recovery mode to factory data reset ("format") your device.
Tip: If your device becomes unresponsive at any point, you can restart it by holding down the Power button for several seconds.
After following all the Before you start steps above:
If your device is on, turn it off.
Press & hold the Volume down button. While holding Volume down, press & hold the Power button until the phone turns on. You'll see the word "Start" with an arrow around it.
Press the Volume down button until you highlight "Recovery mode."
Press the Power button to start recovery mode. You'll see an image of an Android robot with a red exclamation mark (you may also see "No command").
Press & hold the Power button. While holding Power, press the Volume up button once. Then release the Power button.
Press the Volume down button until you highlight "Wipe data/factory reset." Then press the Power button.
Press the Volume down button until you highlight "Yes" (or "Yes - delete all user data"). Then press the Power button to select it.
After the reset is complete, press the Power button to select "Reboot system now."
When you're done, restore your data.
My biggest issue was not realizing the second menu was available. After getting "No Command" the power and vol up buttons are what get you to where you can use adb to sideload even if you never unlocked your device. This might work with a normal marshmallow OTA (Search for "Factory Images for Nexus Devices") but I used the N preview 2 which can be found by searching for "volantis-npc91k"
This had me fuming for a few days... No way I was sending a nexus device back and paying shipping for bricking after a stock update.
NOTE: Sorry I had to remove the direct links. My profile doesn't have enough posts yet. Really dumb, but I get it. Hope this helps.
Thanks for your help. I will try it this week.
Pretty bummed about this, I didn't have a lot of stuff on there but don't like having to deal with this.
Do you know what could have caused it?
-J
Had same issu with May update and applied the N preview OTA (that's the only thing you can do on a locked bootloader).
Once booted in N preview, I've enrolled the device in the beta program, then retired. Few seconds after, I've received the downgrade OTA, and no more issue.
Before doing anything else, I've unlocked the bootloader so at least it if occurs again with the MOB30G, I will have some more access !

Nobody knows what causes this, maybe a corrupted download of the OTA.
It happens to people's devices nearly every month when an OTA is available.
Try sideloading the failed OTA (linked above) again first before taking the Android N route.
Google Now provide full block level OTA images, so they can be sideloaded onto your device no matter what version your on.
https://developers.google.com/android/nexus/ota
Use the latest OTA image from that link, instead of sideloading the patching OTA zips.
I can't seem to sideload the package. My computer doesn't detect that a fastboot device in connected.
I am trying a factory reset now? If that doesn't work, I guess I can try the N preview? Other suggestions?
Thanks,
Jason
@Jsunn Make sure you have the correct drivers on your computer, Nexus Root Toolkit has a driver installation guide.
Check that your in fastboot mode and your device should show up in device manager as
Android Device - Android Bootloader Interface
@corkiejp, Thank you for the tip. That was it and I now am back up and running. I am back on the May 1 Security update. I'd really like to avoid having to do this again in the future. Do you have any suggestions? i.e. should I always sideload the update? Customer ROM etc?
Thanks,
-J
@Jsunn What was the trick? Reinstalling drivers, i Guess.
Remember to Enable OEM unlocking in developer options.
And if you have already factory reset? It might be a good time to Unlock Your bootloader with "fastboot oem unlock".
So if anything goes wrong in the future, you will have the option to flash factory images.

It was the drivers, I didn't think to check that the first time. I am going to unlock the book loader, I was thinking the exact same thing! I'm just glad to be back up and running.

Warning 2: This Process will erase everything in its path, remember to make a backup of your internal memory.
This series of steps is aimed at inexperienced users, if you think you are missing or there are many steps, this guide is not for you.
Without more to say, let's start.
How to re-lock bootloader:
1. Turn off your device.
2. Press Bixby Volume down and connect your device to a PC to start the download mode (now you can release both buttons)
3. Read the text below on the Download Mode screen
to block or unblock the Bootloader.
4.- Long press the vol (- or +) button as best suits you.
LOCK BOOTLOADER:
5. Long press the volume up button ( ) until the computer is restarted (this will erase your data and restart automatically). :fingers-crossed:
Ready! Now you have a device with an OEM lock.
Good luck my friends!!!

Thank you for posting this. I've had this method work once before but i am in a bit of a pickle at the moment.
I no longer get the options to 'long press vol up' which i think is the key to re locking the bootloader. Have you or anyone else got any idea why that would be?

It has definitely worked before but not having much luck now. Maybe the latest software update has blocked this method?

Can you tell what exactly you already did with your phone? Did you unlock bootloader, re lock bootloader, then unlocked it again and then actually rooted it? And now after you unrooted your phone you can not re lock bootloader?
I am asking because I suspect that you can not re lock you bootloader again after you actually have rooted your phone once. I am suspecting I only read a post from a guy who managed to re lock is bootloader but he never actually rooted his phone once. So in other words after you tripped knox (which seems to only happen when you install magisk) you may not be able to re lock you bootloader (ever) again.

Yes!! You hit the nail on the head!! So i was able to re lock bootloader once before but i wasnt successful in rooting the phone. After i then successfully rooted the phone with Magisk i restored back to normal and no i cannot re lock the bootloader.
It seems as though a few people have said you can't re lock it after successfully rooting! Quite frustrating!!

I see. There is another method, that seems to work, tested by @robbo1947 that he explained here.
robbo1947 said:
Assuming you had the standard Samsung ROM (you hadn't flashed a custom ROM)
Change OEM switch while rooted, exit settings, no need to flash stock firmware.
Power off phone.
Press and hold Bixby and Volume down, whilst holding connect with USB cable to computer. Release buttons when Download screen appears.
Long press the Volume up.
At this stage, the phone will wipe the data and overwrite the Magisk modification then reboot.
You should now have an S10, standard boot screens, stock ROM and no root.

I look forward to your findings. As i am running my phone as my daily driver now i am hesitant to re root it if this method wont work. I have my fingers crossed though
samsung doesn't allow you to unlock and then lock back the device multiple times. It only works once, then your bootloader stay unlocked for ever.
I I had root and twrp on my s10 + but I quietly put the last nobrand ASE7 firmware back and I re-locked the bootloader without any difficulty I no longer have any warning messages at startup and in the developer options I have the oem option working like new.

OK, sorry for delay in getting back to this question of locking and unlocking the bootloader on the Galaxy S10.
During the last few days I have locked, unlocked, locked and unlocked again, probably 15 or 20 times to test various scenarios.
Please remember, each time you lock or unlock the bootloader all of your data is wiped.. any Root will also be gone. You will also be needing your current firmware.
This is for the Galaxy S10 without TWRP.
Scenario 1. Your phone is rooted with Magisk.
Go into Developers options and check OEM options, the switch must be ON (to the right). If it isn't turn it ON.
Turn off your phone. Press and hold the Bixby and Volume-down button, then connect with USB to your computer. (The cable shouldn't be connected until after you press the buttons).
Within seconds of USB connection the Download screen will appear. You will see 3 optiions, choose and Long press volume up and hold button until you see the 2 options at bottom of screen. Choose and hold volume up until screen goes off. Then the S10 logo screen will briefly apppear, before it flicks back to the Download screen with the words 'VBMETA: Error verifying vbmeta image etc' at the top, as the image below.
This is all good so far. Leave the phone exactly as it is with this screen showing and make sure the phone is still connected to the computer.
On your computer, fire up Odin3_v3.13.1, you can leave the Reboot option in Odin ticked. Locate your firmware on your computer and put the 4 file parts (BL, AP. CP and CSC) into Odin.
Let Odin finish.
The phone will reboot ready for setup.
The Unlocked bootloader warning screen will be gone.
Scenario 2. Your phone has been rooted but isn't now, and the greyed out OEM switch is ON
Easy, turn off your phone and proceed from the 2nd paragraph of Scenario 1.
Scenario 3 Your phone has been rooted but isn't now, and the greyed out OEM switch is OFF
Sorry, but in this situation, you are going to have to root your phone with Magisk as the OEM switch will only be available when rooted.
When rooted, proceed as Scenario 1.
Scenario 4 Your phone has never been rooted, and the greyed out OEM switch is ON i.e. you unlocked the bootloader but never proceeded to root the phone
Turn off your phone and proceed from the 2nd paragraph of Scenario 1.
If you want proof that I have locked and unlocked time and time again see HERE

No dramas, thanks heaps for your reply.
So it seems I am in scenario 3 meaning I'll need to re root my phone which is fine. However, when I hold down the bixby and volume up and plug in I don't get the option to long hold volume up which I previously did. I only have press volume up or down. Is this because my bootloader is already unlocked? I should still be able to re root my phone in this scenario shouldnt i?

Yep, your bootloader is unlocked.
When you have re-rooted and you go into Developer options you will be able to control the OEM switch and ensure it is ON.

Yep, your bootloader is unlocked.
When you have re-rooted and you go into Developer options you will be able to control the OEM switch and ensure it is ON.

Awesome. Will give it a go in the next day or two and report back but given your success I'm hoping I'll have the same.
Cheers

You sir, are my hero. It all worked perfectly and i no longer get the bootloader warning screen and my bootloader is now relocked!!
For anyone else having this problem, i too can confirm that this method works. The only issue i had was that for some reason, i was stuck on the Samsung flashing boot screen for nearly half an hour. A simple reboot into recovery(hold power and volume down for 7 seconds to shut down and then quickly hold power, vol up and bixby) and wipe factory data then system reboot fixed it.
I can also confirm that after doing this and re locking the bootloader, i now have access to all apps that i was previously having issues with and my google play store recognises my devices as certified.
I now have a fully working and functional device. Thank you again.
if i revert to stock rom after root and samsung status says official and relock bootloader will be able to get otas again???

How to unlock Bootloader Samsung galaxy A10?

Recently, this is a question to be asked by me, but since I've found the answer I'll share it with you.
Bootloader Unlock
First, you need to unlock both USB debugging and OEM unlock in your developer mode in your phone.
After that, backup every important file in your phone in your sd card or any storage (If you don't have then skip backup)
After you have backup and everything follow this step:
1.Press and hold volume up and down as well as the power off button., release if you see changes in your screen
ALTERNATIVE: If the method above doesn't work then proceed to this.
1-A. Plug in your phone while being power off in your pc using USB and then hold volume up and down. release when your screen changes.
If none of the above doesn't work, you have to try it again and again. Sometimes there is a bug that delays your button. I tried these methods 5 times before one of them work.
After that, you'll find blue screen or anything in between. Hold volume up.
This will leads you to a screen where it needs your permission to unlock the bootloader. Just press volume up to confirm.
And boom! Done! Hope it works. if you encounter any problems just comment below

Press and hold Volume Down + Volume Up keys together, then while pressing these keys connecting the phone to PC with USB Cable Data, release all keys when Download Mode appears.
Now long-press the Volume Up button to unlock the bootloader.
Again press Volume Up key to confirm the unlocking.

Question "Alternative" menu

Good afternoon,
I have a question:
If I press the "VOL -" and "POWER" button, a menu appears with three options:
1.- Power OFF.
2.- START.
3.- Restart Bootloader
1 and 2 are clear, but ...
What is the use of 3?
What does?
Is it dangerous to use it?
All the best

the 3rd option's meaning is... well, in the name: restart your phone into the bootloader mode again. That menu is the bootloader, so selecting 3 will restart your phone back into it again
Wait, if you can start phone in bootloader mode, then we can play with fastboot and its backup methods?

Well, maybe? Or actually not, cause the phone's bootloader is locked, and there's no way to unlock it at all (Nokia patched everything in order to prevent people from unlocking its phones' bootloaders)
Mine is stuck on this menu

I'm pretty sure that you're going to be stuck in that menu, forever and ever, until when someone manages to unlock the bootloader. Just... give up any hopes of unlocking those Nokia phones, and use them normally for now.
Thanks

no need to, I'm just someone who is frustrated with how Nokia treats their customers
