My TF201 is well and truly out of warranty now so I thought I might try and get dual boot to ubuntu running on it. I’m still trying to find some up to date instructions, and kind of feeling my own way by amalgamating approaches from various sources. I’ll let you know how I get on.
In the meantime, when you are trying to install an image via fastboot and you keep getting stuck at:
< waiting for device >
with no response; try running it with sudo!
