[Root] J320A/J320AZ alternate method, without Kingroot!! - Samsung Galaxy J3 (2016) Guides, News, & Discussio

**does not yet work for 7.1.1**
Using a PC to root seems like moving backwards compaired to a 'one click' apk. but we're already at the PC to flash eng_boot, plus this new method is so much faster...so here we go
Features:
SuperSU 2.82
Init.d
Wifi fix
Flashlight fix
Issues:
For the wifi fix I just copied an edited J320a build.prop
So J320AZ users will see J320A in about device, and will have to reassign notification sounds. (Hope to fix it in the future)
Needed Files:
Odin
Root_J320A.zip
Procedure:
1. Unzip both files.
2. Run Odin click the 'AP' button.
3. Navigate to Root_J320A/bin and select sm-j320a_Engroot_601PJ2.tar and press "Start" (make sure NOT to check re-partition)
4. After it completes sucessfully, leave the phone hooked to the pc... and then wait, wait a good 2 or 3 minutes after its booted.
5. Once 2 or 3 minutes has gone by you can navigate to the Root_J320A folder.
6. There you'll see root.bat, double click that let it do its thing.
6a. If at any time during the script you see "adb out of date. killing..." hit the x to close the window and restart the script.
*This may work on J320AG models but make sure you check oem unlock from dev settings first... and let us know how it goes
Enjoy

Excellent! This works perfectly! Thank you so much for posting this.

J320A PC9 worked perfectly!

March security patch
Hi man, this method support the march security patch, or are still in january security patch

I tested on AQD2 so it'll work on AQC1 too.
I assume it'll work for all 6.0 updates we get.

This works perfectly. Thank you!
I suggest you put 'root' in the tile, otherwise google cannot find it.
I googled 'j320a root', google only links to ashyx's post which doesn't... well maybe only mine phone.

I am new to this root bit.
Possibly I have done something wrong. I read your instructions carefully and quit didn't understand where the unzipped files should go. Do any of these have to be placed in the phone's directory?
Failed on my AT&T SM-J320A
I wonder if it has anything to do with the new update pushed out recently

@JeffF73
Run Odin and Click ap.
Navigate to the directory where you unzipped root_j320a.zip.
In that folder you'll see a bin folder, inside that is sm-j320a_Engroot_601PJ2.tar, which needs flashed to the phone.
Once that's complete, let it boot and wait.
Then run root.bat

Hello DamienMc Thank you for your reply and help. I figured it out. I had to put my phone in "Download Mode" by holding down Volume Down, Home Button and Power button while booting. Then I was able to use Odin without failing. This solved all my problems thank you

Is it safe to flash this after doing this?

Yes, that has selinux set to permissive as well, although there's no real difference. The build.prop differences are noticable tho...I plan on doing an update to this, just have to figure out how to tell if it's A or AZ from adb

Yes, it works for QC1. However, you may need to replace build.prop in /bin from QC1 with WiFi fix before root.
I did notice that after root, the contents of /Android/data folders in both internal storage and external sd card are hidden from PC. Before root, both are visible from PC. Any thoughts about what cause the changes?
Will this work on July security patch?

Thanks, I just needed to install this to use adb to uninstall an update I did to System UI because it would continuously crash.

Probably the eng_boot we use, it breaks the flashlight and wifi passwords too... it does work on j320a July update, so I assume it'll work on j320az update too

Reflash CSC as well, that'll wipe your device but fix your problem.
Are you sure you waited long enough after the phone booted before rooting?
If at any time during the script you see it say "adb server out of date. Killing..." something is wrong. You can x the command prompt and do root.bat again.

This was the first time i ever tried to root my phone and i followed the instructions located here:
https://forum.xda-developers.com/galaxy-j3-2016/how-to/root-samsung-sm-j320a-galaxy-express-t3573628
Well my wifi wouldnt save any passwords , flashlight was broken and my ATT J320A would always want to boot in to recovery mode. I thought i was screwed!!!! Then i seen one link in the thread to this thread where Kingroot was not needed.
I opened Odin and gave a shot and then ran Root.bat file, and the device rebooted wifi and flashlight were fixed and best of all my J3 was now rooted!!!!!
Still working on getting rid of that annoying pop up but all is good, thanks so much for this root and fix from the other thread.

@james2ya If you are talking about the pop that either says something in the order of "Unathorized activities where made" go to the play store, download and install SecurityLogAgent Fix, Open it up and click "Disable Securitylogagent" then restart phone when it asks. This should help get rid of that popup.
