First of all thank you for your work!
I'd like to report the thing that I encountered. When I try to flash Magisk 20.4 I get infinite bootloop do you know what could be causing that?
I'm using v2 ARM64 version of ROM on J530F/DS.
Try with Magisk Canary it worked for me.
Thank you very much for your suggestion!
Unfortunately I found out that the SD card is not working. I don't know if its the SD card fault or ROM fault but I tested 2 SD cards and before that my SD card worked fine (on other ROMs). It works fine in windows.
Does this happen to you too or its just my problem?
Anyways I'm going to move to some other ROM for now.
Nop, all working good for me
Edit: sorry, I misunderstood your post, that is a known bug present in ARM64 build, try the ARM build
