I did the same on friday, and got no error whatsoever. (debian wheezy)
The new version asked me to perform again the bootloading procedure.
There I had some problems, but it was my fault.
I plugged the cable into the USB 2 socket on my laptop, since I had problems with 2.0.7 on USB 3.

Could be this the reason ?
