tether works fine, but wifi repeater fails. Used 2.4G
Wonder if any (minimum kernel requirement) restricted it to start?

[Mygod]

There are no kernel requirements but that error means that it's probably a bug in your custom ROM. This app requires Wi-Fi direct feature. I'd suggest you report this bug to your ROM developer and/or try different ROMs.

By the way, I could try to debug this issue if you could grab a system-wide logcat (meaning not using that button in the app) after reproducing this issue. But I highly suspect that it's a bug in your system and there's nothing I can do about it.

BTW, For the custom ROM, I formated /data and /cache to F2FS. /system is ext4.

Please read again the instructions. FS has nothing to do with this.
