iPhone4s 5.1.1 解除JB

個問題好似唔關你解除JB 事, 似係你之前改過個Windows or MAC 既HOST FILE
先睇下個HOST FILE 有冇改變, 有既改改佢
Windows 係C:\Windows\System32\drivers\etc\hosts

用NOTEPAD 開個HOST FILE
# Copyright (c) 1993-1999 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 host127.0.0.1 localhost

改返咁既樣就REBOOT 部機後再試用ITUES 回復, 應該就可以回復返個固件

要用ADMINISTRATOR 身份至可以開到
方法係先係START BAR 搵ACCESSORIES 再見到NOTEPAD , 再RIGHT CLICK
揀RUN AS ADMINISTRATOR, 之後開左NOTEPAD 後就OPEN 個HOST FILE 就開到架喇
記緊要有ADMIN RIGHT 你至開到同改到個FILE

先係你個WINDOWS START BAR 搵個NOTEPAD, 再RIGHT CLICK MOUSE, OPEN AS ADMINISTRATOR, 再係NOTEPAD OPEN 你個HOST FILE, 咁就改到架喇, 但你要SURE 你係用ADMIN 登入個WINDOWS
