Root Trouble rooting - stuck at "Starting Fastboot USB download protocol"

[akamad]

Hi all,
I have the ASUS Transformer TF300T. I decided to root the device.

I was following the steps as listed on a couple of websites, including here. I successfully unlocked the bootloader (I know this because I get the message in the top left corner when booting the device). I am now up to the step of running fastboot.

The problem is, when I restart the device and get into fastboot mode (using the power+volume down button), I get a message stating "Starting Fastboot USB download protocol". It unfortunately doesn't move on from that message. I checked "fastboot devices" on my computer, but it doesn't pick up anything.

I tried in both Windows and Linux. Both have the same results. If I have the tablet turned on normally, I can run "adb devices" and it shows up (so I'm assuming the drivers are all ok).

Any thoughts or things to try out? I have tried enabling USB debugging and as I mentioned I tried on Linux and Windows.

Thanks!

Problem solved!

Turns out the device doesn't turn up when running "fastboot devices". I proceeded to flash the recovery image and it worked fine.

Yes, i was going to say that at least windows wont show if the device is plugged or not, not even after running the command "fastboot devices", trying to flash something is how you know if its actually connected or not. (found this out doing the NVFlash)

For me is not working, I enter the fastboot command a it tells that file cannot be found or something like that
