Description: How to put the device into DIAG mode.

Does anyone know how to put the device Zenfone 3 Zoom ZE553KL into DIAG mode?

I've tried:
- In Emergency Mode (with Pattern Lock on) - *#3424# - doesn't work
- On powered off device - holding at the same time Vol+ and Vol- while connecting USB cable - doesn't work.

Question: was anyone successful entering DIAG mode for this device? And how?
