[ROM][9][OneUI] Korea's rom for A5|7 2017

As you probably know by now a Korean variant of A7 2017 has recently received firmware update to android 9 and OneUI. I made it working on my international variant and cleaned it up, so I'm sharing with the community.

Code: 
/*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

FAQ
Is it possible to flash stock oreo firmware after using this rom?
Yes, of course. Flashing this rom doesn't update your bootloader.

Some apps (eg. banking, Netflix) refuse to work.
Permissive kernel which is shipped in the latest build doesn't pass SafetyNet. Luckily, there are ways to bypass this such as flashing Magisk.

I have A5 2017, but battery capacity shows 3600mAh.
You can ignore this. That's only in about phone. The kernel knows your true battery capacity.

How to add csc codes
Korean base doesn't support multi-csc. But we can still unlock region-related features by using special codes. I won't post them here, you should search around xda for the specific one that you need.

For example here I will be adding network speed indicator in the status bar. The code for this is:
Code: 
<CscFeature_Setting_SupportRealTimeNetworkSpeed>TRUE</CscFeature_Setting_SupportRealTimeNetworkSpeed>
But you can add something else, too.

You'll need a PC. Steps to take are:
  1. Download THIS zip to your PC.
  2. Extract the zip.
  3. Open system/csc/others.xml with Notepad.

    It looks like this:
    Code: 
    <?xml version="1.0" encoding="UTF-8"?>
<SamsungMobileFeature>
  <FeatureSet>
    <CscFeature_Setting_ConfigOpMenuStructure>GLOBAL</CscFeature_Setting_ConfigOpMenuStructure>
  </FeatureSet>
</SamsungMobileFeature>
    Add your code like below:

    Code: 
    <?xml version="1.0" encoding="UTF-8"?>
<SamsungMobileFeature>
  <FeatureSet>
    <CscFeature_Setting_ConfigOpMenuStructure>GLOBAL</CscFeature_Setting_ConfigOpMenuStructure>
    [COLOR="Red"]<CscFeature_Setting_SupportRealTimeNetworkSpeed>TRUE</CscFeature_Setting_SupportRealTimeNetworkSpeed>[/COLOR]
  </FeatureSet>
</SamsungMobileFeature>
    Code:
  4. Repack the zip.
  5. Copy to your phone and flash.

Now when you go to settings -> status bar you should see the network speed indicator toggle appear. Or any other change that you added.
