I own a Nest 2nd gen and I am having problems rooting the device. This is what I do:
1. Connect the display via USB with my host pc (ubuntu 14.04, 32 bit)
2. Run ./NestAttack-Linux.sh
3. Enter my password
4. Press down the display for 10-15 seconds
5. Nothings happens (Nest boots until the message is displayed "Please attach display to base board").
Obviously Nest is not entering DFU. Also lsusb does not show a device with the expected id.
How can I solve this?
