Acer Iconia B1-A71, RV05RC05, permission problems

I tried to post this question to thread http://xdaforums.com/showthread.php?t=2240029 but as a new user I do not have permission to do so.

I have the version RV05RC05, I have downloaded the corresponding system.img.gz from the thread (as well as the Acer firmware, which I have not used as tablet alreadt had the version).

I have installed the USB drivers to the Windblows 7 home premium. I have tried to grab the system.img.gz several times but process fails. I also have tried to root the phone, with the same error. Here's the output with debug. Any help would be HIGHLY appreciated..

Regards,

Ari
