========================================
There was a prompt to update, but it failed, after that the right controller on my kunai 3 doesnt work anymore.
I saw another thread about this that has been solved.
From what i get, they have updated their firmware.
I've been trying to search in threads, youtube and on the web on how to update the firmware, but cant find it any where.
Please help.
Thank you in advance.

Update :
I would like to say thanks to Asus Indonesia, Asus Service Center Indonesia, and all the nice people at SMI as Asus Distributor in Indonesia.
They cant repair the Kunai3, so they have replaced it with a new Kunai3.
I'm still very afraid to update the firmware, as i dont want to have the same problem.
So please keep this threat open until there's a solution or a way to update Kunai3

Update :
Asus finally do got on their service.
They cant repair the problem with the failed firmware update, so they replace me with the new Kunai 3.

My problem has been solved, but please keep this forum alive, because we dont know whether this failed firmware update will persist in the future.
Now i'm avoiding to update the Kunai3 firmware to avoid the same problem.

Thank you Asus Indonesia, Thank you Asus Service Center Indonesia, and Thank you to all the nice people at SMI - Asus Distributor in Indonesia.

Glad to hear you got a new unit! It's been a year since my gamepad started having this issue and I chose to throw it away because I didn't know what to do. BTW, I also have another problem with my ROG 5s phone and it's really frustrating. I don't think I'll be buying any more Asus products.
