im trying to downgrade from ios 6 to 5.1.1 but having a few issues. without tiny umbrella i'll get error 3194, then with it i keep getting 1600. neither ireb or redsnow work by putting it into pwnd dfu mode. deleting any trace of apple from the host file doesnt even work either, but surely that defeats the point of tiny umbrella. someone suggested creating a custom ipsw from the official one using snowbreeze, but that just says invalid ipsw for both the 5.1.1 and 5.1.1b
I had the same problem but I fix it this way
C:\Windows\System32\drivers\etc
open hosts file as Notepad and put # sign in every line like this:
Code:
# Copyright (c) 1993-2009 Microsoft Corp.#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
# 127.0.0.1 gs.apple.com
#74.208.10.249 gs.apple.com
#127.0.0.1 gs.apple.com
