A5 2017 520W here (Canada, same as the 520F AFAIK) and seems great so far! Dirty flashed the latest rom w/ TWRP and it seems to have fixed some problems I was having from ****ing around with the system partition too much. And it's nice to be on PIE/OneUI over Oreo; it feels smoother &c.
I didn't see any reply on this (perhaps it was obvious answer) - I also wanted to know if switching will break Google Pay (I thought it was possible to upgrade the A520F without rooting?) I know there are tools like Magisk to bypass SafetyNet (but not Play Inegrity?), but as it's for my daughter's phone I don't want something that may require more fiddling in future! Thanks for advice
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.

This should be flashed after flashing the Rom (Preferably after clean rom install).
What does this do?
Adds your country's CSC and could add some features,mods of your choice. By adding the CSC of your country it may enable voLTE and other carrier specific features, voWiFi doesn't work as the Korean Pie Rom does not include voWiFi (WiFi Calling) related stuff.
UPDATE: The previous zip had an issue with the battery cosmetic fix, fixed that. Please redownload.
UPDATE 2: Fixed again, works with the latest rom version.
This build comes with a several week delay, but for a good reason. The kernel drop I was waiting for, as said in the post above, is finally here. Samsung did some smaller driver and security changes to it, so although it's minor it's nice to have the latest thing. Especially since this could be the last one.
In case you haven't heard already, Samsung will no longer push security patches for it's 2017 A Series. You can read more about that in this news post. Unfortunately, this leaves this update as the last A720S firmware we can rebase on. But, of course, we see new roms (which take newer devices as a base) start appearing. And I hope that they can become more and more stable over time. Edit: I got pointed out that because A720S was released a bit later, in july 2017, we might or might not get one another security update.
Lastly, need to thank my friend @Jmackley for covering me with testing and bandwidth issues.
