Yes I didn't set a screen lock as from what I've learned that's what activates frp, unfortunately my laptop has crashed (anyone good at bios pm me) but still no oem unlock and adb isn't working now, pc at work I've got android studios downloaded but I'll refrain from the lock until I can check, still don't know how to pull a signature from a stock image tho... But also in that article it States that oem unlock was enabled even tho there was no setting but they had unlocked boot loaders

Would this be why that auto root wasn't working? That's the image inside the auto root we got
[Samsung Galaxy J3 (2017) Questions & Answers] :
that may be the reason. this is another reason you should definitely not flash a file not made for your specific device.
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
The file name suggests its our phone, thanks to those that have uploaded original roms, eye opener for what the heck our phones our up to. Especially the boot loader file.
[Samsung Galaxy J3 (2017) Questions & Answers] :
Update

Samsung has released a new update a couple of days ago for the j3 prime. It does no major change and fixes bugs and improves security by updating the kernel and the google security patches. Also since i installed the update my phone has been performing better and also a bug with the brightness on the display flickering has been fixed and also themes have better stability.

Sam mobile has uploaded the latest firmware. The link is here:https://www.sammobile.com/firmwares/galaxy-j3-prime/SM-J327T1/TMK/download/J327T1UVU1AQF7/177641/

Our main task is unlocking the bootloader. We cannot find any exploits by using apps or with commands with adb. The only way to root our phone (at this time) is to unlock the bootloader, install twrp (if someone makes one for our device), flash latest SuperSU zip, and run the file that ashyx made to disable dm-verity and encryption. That is the only known way to root this device since both the system and kernel is soo new. (the kernel has been out for about a month now btw)
[Samsung Galaxy J3 (2017) Questions & Answers] KevMetal:
You just need to enable developer settings amd select bootloader unlock option

One line says oem unlock is allowed

The other line shows you havent enabled it in system settings
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Its not an option in developer settings

---------- Post added at 01:13 AM ---------- Previous post was at 01:11 AM ----------

You think by using VS or something similar its possible for unlocking boot loader?
[Samsung Galaxy J3 (2017) Questions & Answers] :
it looks like either samsung or metropcs has intentionally removed oem unlock from developer options to keep us from rooting the device. if somehow, despite the odds, this device gets rooted (which it seems nearly impossible now) then it will be the result of countless sleepless nights from experienced developers who know the android operating system code.
[Samsung Galaxy J3 (2017) Questions & Answers] KevMetal:
Doesnt matter . I will buy this phone soon . But you guys can try the following because to me the bootloader looks unlocked ..

1. In marshmallow a lot of phones just don't have the oem unlock in their menu

2. Just enable usb debugging in developer settings and authorise the pc as trusted

3. Just enable it using adb

# adb enable oem unlocking

# adb reboot fastboot

4. #fastboot oem unlock

*just answer yes to the unlock

---------- Post added at 07:13 AM ---------- Previous post was at 07:08 AM ----------

Oh and by the way ... If usb debug runs and you can select pc as trusted even if adb oem unlock command fails you can still just boot into fastboot and run the command ... only if adb does't pick up the device or fastboot throws a locked bootloader error will you know for certain ....in many phones with the settings option removed the command worked fine in fastboot ...did anyone ACTUALLY TRY ?
[Samsung Galaxy J3 (2017) Questions & Answers] :
the command adb enable oem unlocking does not work. adb reboot fastboot just reboots the phone. I am pretty sure samsungs current exynos devices do not have fastboot mode. the only modes this phone can be in is system (the operating system), download mode (odin), and recovery. so theres really only one way to unlock the bootloader and that is by basically making a new bootloader and flashing it to force an unlock maybe. it would need to be compatible with the device though and be made using the same code as the stock bootloader. Odin gives us the ability to flash bootloaders (very risky and can result in a hard brick that would require a jtag to fix it)
[Samsung Galaxy J3 (2017) Questions & Answers] KevMetal:
So what about getting a bootchain and and bootloader from an J3 with lollipop or mm that is insecure and flashing those with heimdall so we can flash a custom recovery ........
[Samsung Galaxy J3 (2017) Questions & Answers] KevMetal:
Nevermind doesnt work its just a repackaged version of fastboot someone posted in J7 thread

When bootloader is unlocked we can flash twrp like normal with Odin

It may be legit, but will probably be useless.

Samsung have got wise to releasing Eng Root binaries and are now releasing them with ro.secure=1

I say anyone who's good download the full stock image from updato. I have used then for flashing everything
[Samsung Galaxy J3 (2017) Questions & Answers] :
i think that the bootloader may not be locked. when i flashed that az_autoroot file it had been built for another device so that means we need a build of twrp recovery that is compatible with our device to accurately test whether the bootloader is locked or not. So if anyone knows how to code and develop recoveries for android this could be a field day for you. I myself lack any knowledge of building roms and recoveries but i am good at testing builds by others.

While searching through the bootloader code i found out that there was an eng boot file but it requires a special odin and a specific "token" I have even found files hidden in the stock rom files showing interesting things.
[Samsung Galaxy J3 (2017) Questions & Answers] :
you might want to run adb shell and type in getprop. you will not like what you see. I have definitive proof that our bootloader is locked and cannot be unlocked. We might have to give up on root until a system side exploit becomes available from kingroot or some other app. Notice: theres alot of variables shown when you run the command in adb shell. I guess we are gonna go through the same crap the tmobile s7 users went through a year back. their device had a locked bootloader that wasnt unlockable.
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
What Odin? I have pretty much every version Odin3. I have the special Odin used for, I believe, the note 5. But what did you use to view the insides of the bootloader? I use 7zip. Wondering if something better is out there.

i use 7 zip also if you open the zip file and not extract it and click on the file listed it will open up and show 3 bin files. if you click on param.bin it will show a whole bunch of hidden files. i have uploaded a picture taken by my phone showing the files on my pc. and i included the zip also btw.
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Lol I knew about those they are just pictures. Bootloader can be unlocked give me a sec to find the pic in those...

Update. The unlock is just an image in the boot.Img. the second is the image file in it just those lines of text
[Samsung Galaxy J3 (2017) Questions & Answers] :
it can be if samsung adds the oem unlock option back. it seems like we might need to complain to customer service a bunch and that may get them to release an update to unlock the bootloader. they wouldnt want to piss off people again after what happened with the bootloader being locked on the galaxy s7.

i know i checked it.
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Each level is just taking away an image from the list not really hidden files tho. If you look in sboot.Bin you'll see oem unlock value. And in cm bin you'll find it was written using aarch64 Linux gcc crosstool ng linaro, which I have and have been meaning to check it out. So I'll do that tonight.

[Samsung Galaxy J3 (2017) Questions & Answers] :
awesome
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Yea that means its locked right now for flashing
[Samsung Galaxy J3 (2017) Questions & Answers] :
yea true and just saying i have found a thread about the s7's bootloader being locked on all us carriers. samsung has suddenly decided to lock all bootloaders for some reason in the us. our device is a descendant of the s7 operating system wise which means that the operating system will not allow oem unlocking and even trying to find a way to disable the block the os puts on oem unlocking will be impossible because encryption is enabled by default thanks to all new phones now having secure folder and the full samsung knox security built in.

I'm downloading the full rom for our device, once I find a good program that can read and write roms I'm going to get desperate and delete the while operating system and reflash a modified one, I have a Google pixel to fall back on if it kills my phone
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
You're wasting your time. Any modifications to any part of the system partition and the device will not boot.

Unless Dm-verity is disabled it will fail the system hash check.

You can't disable dmverity because a modified boot.img will not flash.

The only way is to flash an engineering boot image.

This should disable dm-verity and boot up permissive.

However just lately Samsung are preventing even engineering boot images being flashed on stock devices.
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
OK, idea maybe lol, what if a file was replaced on stock boot image to unlock boot loader and keep the hash key or whatever encryption the same? I know they have programs that can do that
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
How about the source code for our phone? Would that help???
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
Not sure what you mean?

There is no way to unlock a Samsung bootloader. Only Samsung could unlock the bootloader and they will never provide an official unlock.

You can't modify the stock boot.img either.

Source code is useless on a bootloader locked device.
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Why would the source code be open source if its locked? Specifically this device, I just downloaded it and have been digging thru, the bootloader doesn't appear to be locked from what I'm seeing
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
Samsung are bound under the GPL licensing terms to release the kernel source code.

Irrespective of whether the bootloader is locked or not.

I'm also not even sure how you are viewing the bootloader code and what it is you're actually referring to? Are you using a hex editor?

that is correct but also the bootloader is proprietary. And i think he is using the same linux system that the code of the bootloader was written in. if you back to a previous post i made like a page or two back you will find the bootloader file.

Yes, it was written using aarch64 linux
[Samsung Galaxy J3 (2017) Questions & Answers] KevMetal:
Bobbyp is using Kali linux which is used for network penetration testing ie wifi and network hacking...

I doubt the code for the bootloader would have been written on there .

Bobbyp also went on and on about using some sort of secret / magic code word or phrase or something ...

I think Bobbyp is an enthusiastic hobbyist like myself and might have lost the plot .

Linux is just an operating system ...

Although Samsung could give you a code to use to unlock your bootloader I don't think any of us can create a keygen to generate a valid unlock code ...

Kali linux could give Bobbyp him his neighbours wifi password if he types the right commands in his terminal amd waits a long time but that has absolutely nothing to do with the samsung bootloader

hey dude i am talking with a samsung rep and the rep said official samsung devices come with the bootloader locked.
[Samsung Galaxy J3 (2017) Questions & Answers] :
This is the chat
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
It seems there is some general confusion surrounding OEM unlock.

OEM UNLOCK is a software lock introduced by Google and refers to FRP (FACTORY RESET PROTECTION) and has absolutely nothing to do with a manufacturer locked bootloader.

Irrespective of whether OEM is available or not it cannot unlock a bootloader. It can only remove FRP.

Samsungs bootloaders are pretty much uncrackable. I have yet to hear of anyone actually hacking a Samsung bootloader to some useable level.
[Samsung Galaxy J3 (2017) Questions & Answers] :
oem unlock basically just allows the bootloader to be unlocked. it has only been present on devices android 6.0 and before very few android 7.0 devices have it anymore from what i can tell. Samsung seems to have chosen to lock their bootloaders on purpose with a key only they have (ENG BOOT/ROOT). This may be the death of root on current androids unless root exploits are still available. But then again the s8 has gotten twrp on the snapdragon variants recently and the snapdragon variants was all locked. exynos variants (USA specifically) has had root and twrp a few months before because all you needed to do was enable oem unlock in developer settings. idk why samsung decided to just give the s8 oem unlock and leave this device locked with no oem unlock option to allow the bootloader to be unlocked. Hopefully samsung takes my feedback i given to a rep (which put my feedback into their system)
[Samsung Galaxy J3 (2017) Questions & Answers] KevMetal:
Well yes generally speaking most people use adb and fastboot to unlock the bootloader and you normally have to enable oem unlock in settings for the command to run ...hence the importance of getting to the setting .... However as shown in one of my previous posts you can enable the setting directly via adb in some cases . I don't have the phone so I can't try ........

I think the distinct difference here is in the abscence of fastboot to unlock the bootloader you need to use Odin or Heimdal to flash an .image with an unlocked bootloader ie engineering image

Samsung is not just going to post those all ovet the interweb . You could request an unlock code which samsung could provide you if they wanted too that you could use to unlock the bootloader
[Samsung Galaxy J3 (2017) Questions & Answers] KevMetal:
What is needed is to get a chinese firmware for the phone without locked bootloader and use official samsung software to restore to that firmware ... Pull recovery ...port twrp ....flash ....boom ...if the s8 chinese versions come with unlocked bootloader ........perhaps J3 will be realeased there too
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
Not sure where you are getting that info, but it isn't actually correct.

The Snapdragon S8 does not have a custom recovery. Chinese devices are a different ball game and not applicable to the US Snapdragon version.

As already stated OEM unlock was introduced by Google starting with Android 5.1 and is still present in pretty much all Samsung devices up to the current Android OS. Samsung seem to have removed the option from some recent devices released with locked bootloaders.

As I have already stated it was introduced as a security measure for FRP.

It WILL NOT unlock a Samsung locked bootloader, simple.

They are not the same. Do not get confused with the OEM unlock command used on Nexus and Fastboot devices.

These devices are already shipped with unlockable bootloaders.

Even Samsung devices shipped with unlocked bootloaders have the OEM UNLOCK option in developer settings.

It is used to disable FRP, it is NOT intended to remove a manufacturers bootloader lock.

On a Samsung device it will also prevent unsigned firmware from being flashed even if the device doesn't have a locked bootloader.

When enabling the OEM UNLOCK option on a Samsung device you are NOT unlocking the bootloader.

Moreover you are actually setting a flag that tells the bootloader to disable FRP and to allow unsigned images to flash.

However this is pointless on a manufacturer locked bootloader as even with OEM UNLOCK enabled nothing unsigned can be flashed.

Also the suggestion to flash Chinese firmware will not work either and this is the case for devices shipped with either unlocked bootloaders or locked bootloaders.

The current bootloader on the device will not allow another bootloader to be flashed from a different firmware.

Flashing anything other than the bootloader from the official firmware for that device will result in an instant fail.

Basically what I'm saying is forget about OEM UNLOCK it has no relevance to this device. It is merely causing confusion.

This device will never have a custom recovery with a locked bootloader. It may get root by an exploit if lucky, but it certainly won't get rooted by traditional methods such as SuperSU.

Even engineering binaries are unlikely to work as Samsung has now disabled writable system access in these binaries.
[Samsung Galaxy J3 (2017) Questions & Answers] :
looks like we must give up root for now. maybe kingroot (or any other one click root) will catch up in a few years.
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
Never say never. Rest assured there are many devs working on root for the SD S8. That device currently does not have root, even the engineering kernel exploit that was used on the S7 does not work on the S8.

Something may be found, if it is then there is hope for this device.

Kingroot may find an exploit and is probably the only hope at the moment.

Personally I would never buy a bootloader locked device unless the manufacturer provides an official unlock.

That is the best option.
