Samsung J3 Prime SM-J337A boot.img - Android Q&A, Help & Troubleshooting

Dear friends,
I am trying to obtain boot.img to patch via Magisk and root my Samsung SM-J337A.
The problem I face is that after much research I'm still not sure if I found the compatible boot.img for my device.
Originally, the SOFTWARE INFORMATION for my phone is as follows:
*** SOFTWARE INFORMATION
Android version
8.0.0
Samsung Experience version
9.0
Baseband version
J337AUCU3ARJ1
Build number
R16NW.J337AUCU3ARJ1
I wrote it down, but not all of the SOFTWARE INFORMATION. Only the information shown above.
But after a few days my phone received an update.
After update this is the SOFTWARE INFORMATION:
*** SOFTWARE INFORMATION
Android version
8.0.0
Samsung Experience version

Perhaps I found the ROM for the original software. These are all the file names:
AP_J337AUCU3ARJ1_CL13465503_QB20325568_REV00_user_low_ship_meta.tar.rar
CP_J337AUCU3ARJ1_CP11051172_CL13465503_QB20325568_REV00_user_low_ship.tar.rar

COMBINATION_FAC_FA80_J337AUCU3ARI1_FACFAC_CL13704061_QB19717843_REV00_user_mid_noship.tar.rar
However, for the updated system I only find the combination file. Well, at least that is what I think I found. This is the file name:
COMBINATION_FAC_FA80_J337AUCU4ARK1_FACFAC_CL13704061_QB20833319_REV00_user_mid_noship.tar
I already extracted and patched the boot.img for this latest 4ARK1 combination file, using Magisk. But I'm not sure if it would be compatible.
Can you tell me please?

Id like to know more about this myself as well please pm me

I've dug around for this phone too, and found two options for download, however they both require payment. (Easy firmware) after searching online, I found another, official, and free way that you can get the official firmware for the samsung devices through Samsung's smart switch application. The only problem is that the program will only download the rom if you have a available update on your sm-j337a. I'm up to date with the first android pie update on my sm-j337a. If your still waiting for a patch, I would:
Install smart switch both mobile and pc.
Set preferences to preload roms in pc version (download first, then choose to install)
Copy the rom from user 》 documents》 samsung
If this works, please share the rom. My phone is too updated to test it.

Hello this is an old post but hope it helps.
When you are looking for the boot.img that is compatible with your device you have all the right info just don't know how to read it.
The device is the J337A your after you updated Baseband is J337AUCU4ARL1. To know what bootloader Rev. you are on you count 4 spaces past the model number so J337A UCU4 you are on Rev. 4 so just download the appropriate software for that bootloader and extract the AP file with 7zip you find the boot.img in there.
hope this helps.
