When trying to install ubuntu touch on my TB-X605F get the error message: "
Error fastboot: flashing_unlock: Error: {"error":{"code":1, "cmd":"fastboot flashing unlock"},"stderr":"FAILED (remote 'Need wipe userdata. Do fastboot oem unlock-go'')\nfastboot: error: Command failed"}
I'm in developer's mode and fastboot mode. How to solve this problem?
Thanks!
