nroot/unbrick Galaxy S2 SGH-T989 I am having problems trying to go to this screen



but the process ends me up on this screen



My process:


Turn off device
Hold power volume up and down until a vibration
Event: shows the end screen but not the warning screen


Can someone guide to get to the warning screen so I can connect directly of computer and access it by odin?

Url of what I am trying to do
When starting your phone in step 2 of your example, hold the volume down only. Once the warning screen appears, then press volume up.
