I rooted my Asus Transformer Prime and tried to install a custom ROM but I managed to fail. I selected the option to wipe data from the table in the bootloader menu (accessed it via holding power button and volume down) and then I cancelled it by turning the device off because I wasn't supposed to select that. It seems this wasn't wise...
I tried to boot the device but now it's stuck saying "Asus" in the middle of the screen. If I try to power it off, it turns off but immediately it turns back on.
I can't access the bootloader menu. Fastboot nor ADB sees the device via USB.
How can I restore it?
