I can't find much info about this phone, is it possible to root it in a similar manner to the other J7 variants?

Please someone help!
I know that most of you genius cell phone programming people have the nicest newest phones but some of us need to purchase the lower-end ones because its all we can afford. And because I can only afford this phone with its tiny little 16 gig bull stuff I really really would appreciate it tremendously if you guys could take the time out of your day to find out a way to root my device. Please someone one I'm begging you.

Really interested in rooting J7 Crown
I'm also interested in rooting my J7 crown. I bought 2 more for my kids as well. Going to be using them with google fi so I don't want all the samsung/tracphone/straight talk software, just a clean install of basic android.

Did some digging around trying to figure out the specs on this phone:
Chipset: Exynos 7884
CPU: 1.5GHz Octa-core
GPU: Mali G71
RAM: 2GB
Internal Storage: 16GB

I also found this about the Exynos 7884:

Also I'd be willing to verify images, but I'm not a developer.

boot.img
i too have this device and if someone can give me a quick rundown on how to pull the boot.img, I'd be more than happy to share it!

I obtained an inoperable device from a friend. He tried rooting, tried flashing, even tried to flash a factory binary thinking he could circumvent Straight Talk's ridiculous bootloader unlock policy, but in the end, he pretty much bricked it. It wouldn't boot into recovery, it wouldn't boot into download mode, and it was stuck in some sort of device test mode. I was able to find out that in that factory binary mode, Odin was able to recognize the device and connect to it. I flashed the BL, AP, CP, and CSC files in Odin 3.13 I think was the version. Now it's back to stock. On the plus side, doing so removed the Google account associated with the phone. I am trying to pull the 'boot.img' file so you can patch it.

Hey Trip do you have the firmware you flashed for the j7 crown? I sure could use it? pm me if you can

Not being able to root this thing is terrible. There are firmware files for it out on the Internet now, but I have not been able to make any progress with working on this thing.

If anyone has anything they would like to add to what I am posting in order to be more specific or definitive of what I am attempting to discuss, please, do not hesitate to post it.
There are things encoded at the hardware level that do not get changed or flashed when flashing Samsung devices, there are hardware components that have their own independent "firmware", so to speak. These components retain their original firmware regardless of what you flash on the device's internal memory(this is very similar to the BIOS chip in your PC that stays the same regardless of what OS you install or how many times you wipe the system and reinstall the OS). If the software that we flash on the internal storage does not pass the signature/security checks encoded in these components that have independent firmware at first boot, the device becomes software-bricked or can even be hardware-bricked. In other words, there are hardware components that are checking the bootloader to verify it is the correct bootloader, if not verified, the device fails to boot at that point(this usually results in a hard-brick), if verified, the bootloader checks the software that it is about to boot, if verified by the bootloader, the device continues to boot, if not verified, the device fails to boot at that point(this usually results in a soft-brick, but can potentially hard-brick). Software-brick is potentially repairable, hardware-brick is not repairable without new hardware replacements or expensive external hardware components and software tools for PC and some rather complicated methods to perform a hard-brick recovery.
In some ways and some instances, it can be a mixture of hardware level checks, bootloader checks and kernel checks before it even gets to attempting to boot at the software level. If these checks don't all agree with each other, the device cannot function properly, sometimes, not at all.
All of this is to say that 1 of 2 things will likely happen when flashing Refine firmware on our devices.
1) our locked bootloader will possibly block the install due to the refine firmware not passing our bootloader's signature/security checks.
Or
2) the firmware might successfully flash without any errors but will potentially brick the device on first boot due to not passing the bootloader's signature/security checks.
If you feel like being a trailblazer, take the chance yourself and see if it works. The rest of us choose to not take the chance in order to prevent a "worst case" scenario.
Side note****
I would like to know how they got Modaco Superboot to unlock bootloader on a Samsung device. Modaco superboot uses fastboot commands to achieve it's purpose. Now, here's the real question, how did they get fastboot to do anything to a Samsung device when Samsung devices do not even have fastboot functionality, no fastboot mode, no bootloader mode? Samsung has it's own version of "bootloader mode" but it isn't the same thing as the "fastboot related" bootloader mode. On Samsung it's called Download Mode which is only compatible with specific tools, not fastboot.
ADB works perfectly fine on Samsung, but fastboot can't do anything with Samsung.

Yes, several times, with several additional modifications trying to get it to work, but it is pointless, it still blocks the patched .img and also still blocks TWRP.
I chased this for weeks on end trying different tricks and methods, nothing worked, didn't even get close to working.
On engineering firmware, OEM unlocked, RMM/KG status stated "checking", RMM/KG status not set to pre-normal(which should allow patched .img or TWRP to flash). But still no success, regardless of what is tried. I've tried everything except finding/buying a ENG root firmware(which doesn't exist for this device). I've exhausted every method and tool that I've learned/discovered in all the years I've been dealing with android customization, NOTHING works, period. We just are not going to get past the locked bootloader on this device, it is a pointless endeavor, Verizon/Tracfone has this device locked down air-tight.

Not necessarily, the "OEM unlock" setting does not always, itself, unlock the bootloader. Sometimes, it is a setting that puts the device in a state that the bootloader "can" be unlocked via the compatible unlock method, if one exists for the device.
For instance, on a fastboot capable device, one would enable the "OEM unlock" setting, then boot to fastboot mode and issue the correct fastboot commands to unlock bootloader, or, after enabling the setting, one would obtain the necessary information/codes to unlock then visit a specific website to enter the info/codes and maybe use a couple of specific PC programs to unlock.
In a manner of speaking, it can be a kind of cover over the keyhole that allows you to insert the key to unlock the lock, you just need the correct key to release the lock once the cover is removed from the keyhole.
But, you are right, in a sense. Some devices that have this setting are completely unlocked just by toggling this setting, but this does not apply to all devices, in all cases.
