I finally got my Runbo X5!
Mine was delivered with 4.0.4, and it runs smoothly, however, when I try the update feature I have the same "sim not registered to server" issue.
I used the "many ics root"
method, it works on the runbo in normal mode. Just don' forget to disable usb storage mode (mine was in camera mode during the hack). Unfortunately, I don't have the rights to post in that forum to report it's working with this model... it would be nice if someone could report to Bin4ry.
