Am i doing something wrong with upgrading?

Hello,

I can't upgrade my GT1. Maybe i'm doing something wrong? I am using the usb to usb cable. Running USB burning tool until the firmware has loaded. Then press start and then i am trying to do put a small think in the hole on the back and then put the usb cable in the beelink. Nothing happens, i also don't feel the button in the hole is clicking, while the needle in deep enough inside it. I don't have the power adapter plugged. Do i have to? It worked before so i have no idea why it's not working now. Like i said i can't hear any click. Hopefully someone can help me out.

Thanks in advance
