I can't update or downgrade my iPhone 3GS, Firmware 4.3.5 tethered with redsn0w.
Whenever I try to update it, I get a "device isn't eligible" error. I researched on how to do that, like changing host files, but none of them worked for me. I use OS X Snow Leopard.
## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost 188.8.131.52 gs.apple.com
This is my host file – not sure if it's the orginal one or not.
