Help with wire Method

Hello everyone,

first of all, let me thank you for all the effort you into this.

I have a problem using the wire method. My tablet won't boot into TWRP. I have no idea what the problem might be, since I am rather new to this. Any help is greatly appreciated. Here is the protocol:

sudo ./bootrom-step.sh

From here on, nothing happens. I don't get the Reboot to unlocked fastboot message.

I then tried:

sudo ./fastboot-step.sh

Your device will be reset to factory defaults...

Press Enter to Continue...

< waiting for device >

And that is all I have. Any suggestions what I can do? Thank you!
