The issue is the kernel itself. For some reason it doesn't even detect the existence of the external sd card as a block device.
Without the block device there is nothing to mount to.

I will wait for stable TWRP, I have experienced with unstable twrp make my device over heat and the battery drain too fast. Rooting file without twrp is still the best right now, I will use twrp when I need to install a custom rom.
Well, based on my experienced...
Flashing SuperSu 82 makes my lockscreen freeze for a couple of sec so I decided to flash SuperSu 79 SR1 and that fixes it...

Your issues have absolutely nothing to do with TWRP. It's impossible for a recovery to affect the OS.
The 2 are completely independent.
Thanks for your explanation @ashyx, I will flash the twrp. Do I need root again after flash the TWRP?
You don't need to root at all. I'd suggest not rooting and see how it goes or root with V2.79 as others have reported similar issues after rooting with V2. 82.
I don't usually get time during the week, family man, but will see.
Are you competent with ADB commands?
Yea i know adb i doo al rom porting stuffs
Today it was raining aalll in mumbai so maybe tomorrow ill be also busy
But if u make a build plzz send......
@ashyx
I have flashed the TWRP and Root it on SM-J730G, everything works. I am not immediately press the volume up key when to get out from the download mode, and the phone restarting normally to the system first, but when I turned power off and enter the twrp recovery again, That is not replace the twrp recovery with default recovery. If you want to install the supersu, I suggest install it from SD Card, it really easy. I have recorded it, you can watch it on https://youtu.be/OM4X5CCMM7Y 
i try but no luck the problem is i don't have dialog box directly say device unautorized
sorry working i remove adb from kernel and work fine now

MTP working
ADB working
SEANDROID warning fix
TWRP and Kernel built from latest source
Raw SYSTEM image backup
NTFS support
F2FS support >> To be added

You flash this at your own risk. Please ensure you have the stock ROM to hand downloaded from SAMMOBILE in case of problems. This will trip the knox counter.
Instructions:
Flash with odin in the AP slot.
Put your device in DOWNLOAD mode.
Uncheck Auto reboot.
Load the respective file below into the AP slot and hit start.
After flashing and ODIN reports PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding POWER + HOME.
You should now see TWRP recovery.
FAILURE TO FOLLOW THE ABOVE STEPS WILL RESULT IN TWRP BEING REPLACED BY STOCK RECOVERY
NOTE: ON SOME ANDROID 5.1.1/6.0/7.0 DEVICES IT IS NECESSARY TO GO TO:
Settings -> Developer Options -> OEM unlocking
AND ENABLE OEM UNLOCK FIRST OR YOU MAY ENCOUNTER 'BLOCKED BY FRP LOCK' WHEN FLASHING.
DOWNLOAD:
twrp_3.2.1-1_j730gm_16318
To Root:
Flash the latest Magisk release with TWRP:
[https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445]
To disable forced encryption and mount internal storage (/DATA):
(Note this MUST be flashed after SuperSU if you intend to root)
1. Boot to Twrp
2. Format Data partition using FORMAT DATA button under Wipe options.
(Note: This will wipe the internal storage)
3. Check DATA is mountable.
4. Install Magisk
6. Reboot
DEVICE TREE: soon
