I am not sure if there is a loader for the starview 6\7. I went to krypt after Nag3 came out, but I have done box to box flashes on older Starviews, I am not sure if that option is still in the menu on newer ones, it was S\W transfer. If it is there still, try and do a box to box flash from your mates using a NULL modem cable.
If it is,
1- Connect the two boxes with a Null modem cable.
2-Your Friends box would be the Master and would be connected to the TV.
3- Your box would be the Slave and pointed away from the remote control so it does not pick up the remotes commands.
4- Switch both boxes on.
5- Go to the S/W transfer and press OK then you should see the data copying from your friends box to yours, when complete both boxes should reboot and your box flashed.
