I am trying to downgrade an iPhone 3GS from 6.0 to 4.1. No luck so far. It has SHSH blobs for 4.1, and I am using TinyUmbrella. I am getting an error 20. I have disabled my firewall and ensured all ports on my router were open.
Maybe I am doing something wrong? Itīs been a while since I have done this, maybe things have changed since.

Put iPhone into Normal Dfu mode.
Don't use Tiny Umbrella as apple still signs 4.1 so u verify your 4.1 restore with apple server.
Make sure u delete the line > gs.apple.com in your hosts file.
You should now be able to 4.1.
If your iPhone has iPad bb installed, you will error at 1015.
Use exit recovery from TU to kick it out.

Remove the battery, put it back and try again.
