For all Samsung Galaxy J701F users - Test Root with bypass defex

With the last TW firmwares Samsung released A new security called [Defex].
And this protection prevent any process to run as root if it was not in the whitelist that provided in the kernel source code:
Code:
/system/bin/run-as
/init
/sbin/
/system/bin/
/system/xbin/
/system/vendor/bin/
/vendor/bin/
/tmp/update_binary
So if any app wants to run an elf executable in [e.x "/data/local/tmp"] like [Titanium Backup] of [ES File Explorer] the elf executing process will returns with Killed.

The first release of this protection was in Galaxy A8 2018 (SM-A530F) Android 8.0.0
and then released in Galaxy Note 9 (SM-N960F) 8.1.0
And all of these protections was defeated by some hex patching.

Now it is the time for SM-J701F:
Samsung released the source code of J701F today so i downloaded it and get a new patch to defeat the security

The magisk manager doesn't show any modules available for download but for root it works fine.
Thanks a bunch for fixing root. I didn't upgrade until this was available!

I recently updated my J7 Core to Oreo and after that, my oem option is gone and download mode displays RMM State: Prenormal. It hasnt been rooted before and whenever I install a font or themes, nothing shows up. What should I do?

i tried rooting my fone and it booted successfully.. but after few moments the antivirus kept on prompting to reboot the fone

I don't know if you have 3rd party antivirus or not, but if so you'll want to whitelist what its complaining about if you can, otherwise uninstall or freeze the antivirus.

You also want to freeze down Security Log Agent, possibly Device Security, and also Knox related apps are important. There's lots of apps to freeze things down but I've used Titanium Backup for so long that I haven't payed attention to other ones and don't know what they're names are. It can be done at the command line as well. Search for what works and is free, because that feature I think isn't free in non paid version of Titanium backup.

Also, if you've gotten errors at TWRP not being able to mount /data you might want to install the Magisk apk separately and then update the Magisk app from the running phone environment assuming it lets you.

Magisk has been updated a couple times since the missing file was first uploaded so perhaps this isn't necessary anymore.

what im referring to is the device security, after the succesfull bootup from flashing magisk..
