When open the app, it says "Currently not available"

[Praditia Nur]

As the title suggest, i've build a rom with RevampedFMRadio bundled. I've follow the tutorial steps too. But when i open the fm radio app, its says "Currently not available". Here the screenshot and some logs that i take.

Do you know how to fix it?

The error is:

E android_hardware_fm: open_dev failed, [fd=-1] /dev/radio0

It means that the JNI library cannot establish communication with your kernel driver. Ensure the /dev/radio0 path exists. If yes, then check if your init scripts can properly init the FM driver when hw.fm.init prop is set:

And the perms to allow writing to sysfs node:

p.s if your're rooted, you can directly try this via terminal and restart the FM app:

echo 1 > /sys/module/radio_iris_transport/parameters/fmsmd_set

Ah, okay, thanks for your hints. I dont have hw.fm.init on my .prop too, maybe i should add it right?

Set it to 0 ofc.

One more thing, i see your /dev/radio0 is set to 0666 right?

# ueventd.qcom.rc
/dev/radio0    0666   system    system
