Oem unlock questions - Samsung Galaxy J7 Questions & Answers

http://techbeasts.com/how-enable-oem-unlock-android-lollipop-marshmallow/
This article is pretty much straight forward but i wasnt sure on it cause ive never had a phone with oem unlock in developer settings. From what it says oem unlock is required to be turned on anytime you do any kind of modification or flashing a stock tar.... so it has to be on basicially permentantly correct just to be on the safe side if your doing modifications or have modifications already on your phone?

Everytime I've used OEM unlock was for a device that supports fastboot to unlock the bootloader. Now, Samsung doesn't do fastboot but it seems that you must click OEM unlock to flash (thru Odin) a custom recovery such as twrp.
-sent from this device using this app.

This what someone said online cant be 100 % sure if its accurate..
Quoted text.....
Sadly it backed fires the users who accidentally got themselves boot-looped and forgot to unlock oem.
Like me... Oem locked, and all are stocks no cwm/twrp... All i can do is bring this to the service center. :/
Mistake for me, error for google.

Google Pixel 2 (July Update non Verizon) OEM unlocking issues.

The issue that I'm having is that I am unable to unlock the bootloader even though I should be able to. Here are the steps i'm taking and where the issue happens.
Factory/Wipe reset
Tap about Pixel 2 7 times to get developer options
Go to developer options and enable USB Debugging and OEM Unlocking.
(I Can see that OEM unlocking is enabled).
Then I do "adb reboot bootloader"
and once in the bootloader, I do "fastboot flashing unlock"
Then it tellsme that Flashing Unlock is not allowed and when I go back to the developer options, the OEM Unlocking is greyed out and in the off position and I cannot re enable it no matter what. I have not being able to find anyone with this problem or a solution, any help would be appreciated.
I have tried the above steps many times with no luck, and every time the results are the same. It gives me the OEM Unlock option right after the factory reset, but one I do the "fastboot flashing unlock" it doesn't unlock the bootloader and then it locks the option in developer options.
I updated both ADB and fastboot to the latest version.
Edit #2: running the "fastboot flashing get-unlock-ability" command, returns a (1), which means that it should be able to be unlocked.
Edit #3: Tried to sideload OTA update using ADB and it does not solve the issue.
After factory image, did you reinstall the update? Maybe make sure the update has been completed in total (takes 2 reboots sometimes).
Try: fastboot oem unlock
Definitely a weird issue. Are you on Verizon’s network?
Edit: were you connected to the internet when you did the oem unlock in the developers options?
Edit 2: you have usb debugging enabled yeah?

I did not, I assumed that since it is the latest factory image, I did not needed to update, will try this ASAP.
USB Debugging is enabled.
I was connected to the internet when I did the OEM Unlock under developer options, I tried both connected and not connected to the internet. I tried to change the boot partition using fastboot and it does not allow to do so when in "locked" mode.
oem unlock returns that it is unable to be unlocked. (Sorry, not home now, but will post the actual error when I get back)
I am experiencing this issue also. I'm on my 2nd RMA device. The specific error I get after typing
Code:
fastboot flashing unlock
is
Code:
FAILED (remote: Flashing Unlock is not allowed)
Any help is appreciated.

That is in fact the error I'm getting. I had the OG Pixel and the Pixel 2 rooted since the day they came out and never had a problem, and now with this RMA replacement, I'm having problems, but IDK what could be the cause because with a fresh factory reset, I can at least see the "OEM Unlock" under developer options, so I'm so confused.

My OEM Unlock option will "take" when I click it, but it's disabled again when I reboot.
If they're RMA replacements, there's a possibility you got a Verizon Pixel 2 instead of a Google. This happened to me as well, I just traded for my wife's Pixel 2, because she has no interest in BL Unlocking and all that goes with it. There have been others who kept returning phones until they got one that allowed BL Unlocking. If you purchased from Google originally, just tell them the problem and they should send you another RMA replacement, from what I've seen elsewhere.
Edit for clarification: Supposedly, they've been getting Verizon and Google Pixel 2s mixed up when they get refurbished.

So op, is this the first time you have tried unlocking this rma? If so, sounds like you know the problem and probably have to rma again

Yes. This is the first time I tried to unlock this RMA, just got it a couple days ago. I have rooted all my android phones for the past 4-5 years and never had a problem similar to this show up before. The thing is that I really want to know what is happening at at deeper level, why is this happening, it doesn't make any sense at all because why would that option change if the fasboot flashing command is returning an error, also when I use "fastboot flashing get_unlock_ability" it returns a (1) and not a (0), which means that it can be unlocked.
We'll see, I started the RMA process lets see what they say.

I don't remember where exactly I saw it, but in one of the commands, it tells you whether it's allowed to be unlocked. That's a firm 0 in that spot. Like I said, you likely ended up with a refurbished Verizon version. The only difference, to my knowledge, is that Verizon doesn't want you to unlock your bootloader.
There's already a whole thread about this. Please post there
https://forum.xda-developers.com/pixel-2/help/oem-unlocking-grayed-vzw-pixel-2-t3776763/page5
Bottom line. Google pixel 2s refurbished RMAs are botched for OEM unlocking. There's a problem with their refurbishment procedures that makes it behave exactly like show here
Only solution is trying to convince them to send you a new RMA, but good luck with that.

You now need to convert to Int. version, you can't "fastboot oem unlock" on T-Mo version without a stupid unlock token! Follow these instructions ===> https://forum.xda-developers.com/oneplus-7-pro/how-to/how-to-convert-tmobile-op7-to-t3935947
So I called TMobile and I got the rep to give me a permanent unlock for my phone and I checked the Tmobile unlock app and its says permanently unlocked
After this, you need to enable OEM unlock. See here.
Once you have enabled OEM Unlock under developer options, the fastboot oem unlock will work.

Phone just crashed. Could it be because of an unlocked bootloader ?

I opened up the developer options on my Moto G Stylus and went under OEM Unlocking and selected the allow the bootloader to be unlocked option. That was either last week or a few weeks ago because I wanted to root it and put a custom rom on it. I didn't rooted it yet because I'm not sure what roms are good, I only had cyanogin mod roms on my other phones and I'm not sure which rom is the safest and best to use so I still use the stock rom. I turned on Pandora to play music before I went to sleep. When I woke up my phone was in some kind of recovery mode and said something like the operating system failed to boot. Two options were available, 1- to try booting again, and 2-factory reset the phone which would erase all data. I selected 1, and my phone booted up. Could this be because the bootloader is unlocked? Does having the bootloader unlocked leave it suspectable to being hacked? Could my phone have been hacked?
Switching OEM Unlocking is not enough to unlock, you then must on motorola unlock webpage paste code from your phone and, wait for unlock code in email, via fastboot with this unlock code doing finaly real umlocking...

Would selecting the bootloader option to be unlocked in the developer options make my phone more vulnerable to be hacked?
A few hours later my phone did the same thing and went into recovery mode saying that my phone could not load the OS and might be infected or something. I had the same options to either try to load the OS again or factory data reset the phone. How could this happen?
I factory data reset my phone this time. I just hope I don't have some kind of malware.
Mine was hacked like this. Changed stuff so it won't boot back to original. Got into system files and remote control my phone. Is there a way to get back to original without computer? It's useless now

Question OEM Unlock missing on SM-A326U

Hi guys,
Man oh man this phone...
So basically I'm trying to unlock my bootloader without waiting the 7 days, since I simply don't trust this phone to give me the OEM Unlock option after 7 days...
Before I decided to unlock my bootloader I had been using this phone for about 2 months like normal, sure I uninstalled a ton of bloatware and system apps that I didn't need which MIGHT have been the reason it didn't show the OEM Unlock after months, but the battery life was amazing.
But recently I've been considering rooting my phone, and before I started factory resetting and trying many different things to show the OEM Unlock option, keep in mind I've bee using this phone normally for a couple months, I checked the developer options and not a surprise, OEM Unlock wasn't there.
So ever since, I've tried sooo many things to show the OEM Unlock:
( I reflashed the stock firmware with Odin in between all these methods I've tried )
Also before I list everything I've tried heres the full specs of this phone and the drivers I've installed on my Windows 10
Samsung Galaxy A32 5G (SM-A326U)
T-Mobile, MTK, Network locked, No SIM, NOT Snapdragon
Drivers I've installed on my PC: Google USB Driver, ADB Interface, Samsung Android USB Driver, MTK Driver, USBDk and a few more can't remember the names...
1. Changing date, checking for an update and changing the date back, tried restarting the phone in between, tried turning wifi on and off in between.
2. Combination firmware, got unauthorized error on the download mode screen talking about the pit file.
3. Tried running:
adb reboot bootloader
fastboot devices (It successfully recognized my phone)
fastboot oem unlock: Unknown command
Didn't even run the command...
4. Since its a MTK CPU I had hope for mtkclient https://github.com/bkerler/mtkclient
It just kept asking to connect my phone, tried connecting with recovery mode, download mode and fastboot mode, none of them were recognized
The reason I need a quick way to unlock the bootloader, is cause I will be doing stuff with this phone that might result in me having to reflash the firmware which I can't risk it relocking and have to wait 7 days each time something goes wrong.
I heard that T-Mobile phones bootloader's are impossible to unlock, someone please tell me that is not true...
So basically,
Is there any way to unlock the bootloader? If not why and if yeah, what have I been doing wrong and how?
Thanks guys
7 days what? Tmo A326U doesnt have the option to unlock the bootloader, you need to pay the people here that provide the service. They are the only ones that seemingly know how to get it unlocked, and I can vouch for it.
Seriously... So there's no way to unlock for free, or by waiting...?
Not a bootloader unlock. Its not just Tmo that are locking these down tighter.
You can unlock it for free if you can figure out whatever they do ;-)
Nah idc about a network unlock since I don't have service for this phone, I just wanna know if its possible to unlock the bootloader... I've tried everything

You said not a "bootloader unlock" so I was assuming you're talking about network unlock... Sorry, but should I just give up, there's seemingly NO WAYY to unlock the bootloader of a T-Sh*t phone.
Oh just misunderstanding my bad. I meant you cant wait for a bootloader unlock, but you can wait and maybe they would carrier unlock it later... but thats not what you want anyways.

That's kinda sad, I think I'm gonna just give up, but thanks for the information... Hopefully something happens in the future that allows it to be unlocked soon... Thanks man
I doubt they'll bring it back. OEM unlock that is. My phone is over 7 days old and I did the factory reset by holding the volume down and power buttons and then the volume up and power button and did the full factory reset. OEM unlock is still gone. Yes I got the developer options turned on. I rooted a couple of Nexus 6p's which of course are obsolete now since they were 3G and there is no backward capability. At least I got them used, replaced the batteries myself and can use them as WiFi phones with Talkatone through my WiFi. Read some blurbs about Kingo root working but I'd like to see that someone has pulled it off with the A32. Am under a 2 year obligation but I bought a second one to experiment on. I did that before I found out there was no OEM unlock. Well, if I break one, I'll have a backup. Except the phone is tied to the SIMM and I'd have to bring the backup in to have it reprogrammed.

There was a similar procedure to unlock bootloader on a samsung mtk (A125U) same carrier as yours (T-Mobile TMB and the same applies to MetroPCS TMB) basicaly, you had to flash BL files from the A125W (canadian version) then unlocking bootloader using testpoint (bootrom mode) then using any paid or free app (in my case i use a paid one because i run a repair shop). even if you unlock bootloader using paid tools, it gets locked again when it turns on. (i tested it without flashing BL files)
sadly, i dont have a A326U lying arround to test said procedure.

How to un-freeze an unresponsive Samsung Galaxy A32 5G with reboot, reset, factory reset, odin mode, download mode, android recovery mode & debug mode
Has any one made any progress regarding the missing oem unlock? I know what parameters to add to our kernel v1 to v3 during building to enable oem unlock and add access to fastbootd. Because of project treble our options have changed.

Locking/Unlocking the Bootloader​bookmark_border
On this page
Unlocking the bootloader
Locking the bootloader
Setting lock/unlock properties
Protecting critical sections
By default, most Android devices ship with a locked bootloader, meaning that users can't flash the bootloader or device partitions. If needed, you (and device users with Developer options enabled) can unlock the bootloader to flash new images.
Unlocking the bootloader​To unlock the bootloader and enable partitions to be reflashed, run the fastboot flashing unlock command on the device. After setting, the unlock mode persists across reboots.
Devices should deny the fastboot flashing unlock command unless the get_unlock_ability is set to 1. If set to 0, the user needs to boot to the home screen, open the Settings > System > Developer options menu and enable the OEM unlocking option (which sets the get_unlock_ability to 1). After setting, this mode persists across reboots and factory data resets.
When the fastboot flashing unlock command is sent, the device should prompt users to warn them that they might encounter problems with unofficial images. After the user acknowledges the warning, the device should perform a factory data reset to prevent unauthorized data access. The bootloader should reset the device even if it can't reformat it properly. Only after a reset can the persistent flag be set so that the device can be reflashed.
All RAM not already overwritten should be reset during the fastboot flashing unlock process. This measure prevents attacks that read leftover RAM contents from the previous boot. Similarly, unlocked devices should clear RAM at every boot (unless this creates an unacceptable delay), but should leave the region used for the kernel's ramoops.
Locking the bootloader​To lock the bootloader and reset the device, run the fastboot flashing lock command on the device. Devices intended for retail should be shipped in the locked state (with get_unlock_ability returning 0) to ensure that attackers can't compromise the device by installing a new system or boot image.
Setting lock/unlock properties​The ro.oem_unlock_supported property should be set at build time based on whether the device supports flashing unlock.
If the device supports flashing unlock, set ro.oem_unlock_supported to 1.
If the device doesn't support flashing unlock, set ro.oem_unlock_supported to 0.
If the device supports flashing unlock, then the bootloader should indicate the lock status by setting the kernel command line variable androidboot.flash.locked to 1 if locked or to 0 if unlocked. This variable must be set in bootconfig instead of in the kernel command line in Android 12.
For devices that support dm-verity, use ro.boot.verifiedbootstate to set the value of ro.boot.flash.locked to 0; this unlocks the bootloader if the verified boot state is orange.
I have the A32 5G (64Gb Int. Stg.) & it's the Tracfone Only version or SM-S326DL. After recently receiving word that Android 13 was awaiting us, I quickly allowed my device to receive this very kool OTA operating system update. I mention this, because a week earlier I received an email from my prepaid wireless provider instructing me in detail how to manually unlock my A32 5G handset. So, to be clear, Tracfone notified me in their email how to unlock my device, but whan
this happens to often, to write this off as an app-mishap xda...why?!
(pls. explain this to me, what is really going on)?

I'm wondering too. Could you please pm me what you were trying to post?

Phone essentially bricked with locked bootloader

I have a pixel 3a with a locked bootloader and a very barebones android os on it. It has basically no apps, the only ones shown are clock and settings, the settings app is very stripped down from a regular settings app too. For example, and maybe most importantly, there is no build number so I can't unlock the bootloader. I've tried pressing everything that sounds somewhat related, nothing enabled developer options. The recovery is very barebones as well, it only has reboot or power off options. So this phone is basically bricked.
Is there any hope? Any tools that can force unlock the bootloader? I did find some that claim they can but they seem very sketchy so idk if I want to try those.
Any other solutions are welcome as well of course
Android Flash Tool

Here's the easiest option - back to stock. This site from google does all the work. As long as you can get to bootloader - you are good.

That was the first thing I tried, but like I said, there's no way to unlock the bootloader (as far as I can tell) so it doesn't work
If you can get to the bootloader screen you can unlock it there via ADB and Fastboot:

Try this command: fastboot flashing unlock

That command only works if you allow the bootloader to be unlocked from the developer options, and like I said, I can't enable developer options on this phone
I'm having the same problem.
Did you somehow resolve it yet?
