Magisk / SuperSU patch defex test

Greetings for all,
In the explanation Here for new samsung security (Thanks for @defexer for that)

After some research i found an *EXACT* hex patch code to disable the defex security completely,
with using one hex code.

I rebuild Magisk from the source with injecting that hex patch code into boot patch process
and also added it to SuperSU patch script.

SAMSUNG Models that have the protection:
- Galaxy J6+ - 8.x.x - (SM-J610) - Temporarily solution
- Galaxy A9 2018 - 8.x.x - (SM-A920) - Tested
- Galaxy J7 2016 - 8.x.x - (SM-J710) - Tested
- Galaxy A7 2018 - 8.x.x - (SM-A750) - Tested
- Galaxy A9 Pro 2016 - 8.x.x - (SM-A910) - Tested
- Galaxy A8 / A8+ 2018 - 8.x.x - (SM-A530 / SM-A730) - Tested
- Galaxy J5 Prime - 8.x.x - (SM-G570) - Tested
- Galaxy J5 Pro - 8.x.x - (SM-J530) - Tested
- Galaxy J7 Core - 8.x.x - (SM-J701) - Tested
- Galaxy J7 Prime - 8.x.x - (SM-G610) - Tested
- Galaxy J7 Prime 2 - 8.x.x - (SM-G611) - Tested
- Galaxy J7 Pro - 8.x.x - (SM-J730) - Tested

Waiting for any confirmation for the Not tested models.
Thanks in advance.

Hi Defexer,
In one reply to me you mentioned "... and disable the RMM state after it allows you to flashing custom binaries". I didn't understand what you meant. Could you pls explain? I am not very solid in flashing ROMs. So I need some help

OR

Now that you have done changes is that RMM part still necessary?

Hope hearing soon from you
Thanks

First i'm not defexer.
The RMM state needs to be disabled in custom recovery after or before flash the root to avoid block again,
there is a RMM-Fix zip file on XDA flash it then remove this file
Code:
/system/bin/vaultkeeperd

Hey there guys. The URLs for Magisk aren't working in OP. Can you please share the love once more? :D or at least show us the github commit or hex patch you used.

i dont understand
after install twrp http://s9.picofile.com/file/8339593834/Screenshot_20181011_080810_Settings.jpg

magisk.tar md5 i cant convert magisk.zip to .tar so plz upload magisk.tar or superSu.tar for j730f oreo

Open your device firmware that you flash with odin (version 8) and extract boot.img.lz4 from it then upload it and send the link here

No, still same issue.

The PayPal support team told me that everything fine with it, I don't know whats happening maybe it is a network problem or security issue.
I'm sorry for that and I consider myself received it for your appreciation for my work

    Please I have flashed my Samsung Galaxy j7 Prime g610f with twrp 3.2.3 and had soft bricks. That's the phone refuses to boot pass the logo, and it kept vibrating. Below is a link to my stock firmware boot.img.

    There is a space between .com and /file/xxxx

    In general, I found a kernel already rutted and with defex disabled :)
    Kernel for firmware 8.1.0 models SM-T385 and T385M and T385C
    I will put the kernel in a zip archive, inside a tar archive that can be flashed via ODIN directly to the stock firmware, perform a data reset and use ...
    Titanium works with other programs, too, without asking for root rights ...
    P.S. on the approach of Android 9 Pie, the T385DXU3CSH4 firmware is already being tested :)
    and again there will be a question with obtaining Root rights
