[ZenFone 2 Q&A, Help & Troubleshooting] HungNgocPhat:
It's not working. The detection timer just decrease to 0 without detecting my device.

What I did: plugged the usb cable into my device. It powered on and kept rebooting (like I mentioned in previous post). I pressed power button -> it powered off. I clicked "Begin Download" the timer decreased to 0 without any other signals.

Then I pressed power button, it powered on again and kept rebooting (the detection target counter fluctuated between 0 and 1), so I couldn't flash.

The same happened with vol(-) + power or vol(+) + power.
