I have sort of the same problem, my device is stuck in Recovery Mode, whenever I turn it on it tells me to connect to a computer and open up the zune software and restore it.
I open the zune program and I get the same message as Juan, update unavailable, I do not have an internet connection, the only way I was able to update to Zune software 2.3 was to download it from this computer (internet cafe) then transfer it to a removable hard drive, then transfer it to my laptop.
I do not have any access to internet with my laptop, all computers here with internet require adminstrator rights to install anything.
I am however able to download the official firmware updates and place them on my removable hard drive, is there anyway to update zune firmware without using an internet connection?
No personal internet here in Iraq
Thanks
