IPHONE 4 降韌體 會出現錯誤訊息 1604

[joam7777]

不知道有沒有人跟我遇到一樣的問題

試過網路上好多方式，但是都無法解決.....

有用SHSH備份過原本的韌體版本

韌體版本: 4.2.1(8C148)
4.3B2(8F5153d)

我想要降韌體版本...4.1X版.....

Steps to fixing 1604 iPhone restore error:

1.There is no need to reinstall iTunes or whatever. Keep the same version that you have used to restore or backup previously.

2.Make sure that iPhone is disconnected from your computer and that iTunes is closed.

3.The following step of fixing 1604 iPhone restore error is Windows XP specific, if you are a Mac user, you may have to locate the folders yourselves as I am not sure: Go to folder C:\Documents and Settings\<username you use to login to windows>\Application Data\Apple Computer\iTunes\iPhone Software Updates. You will see one or more files. Cut and paste them somewhere else. Do not delete them in case the steps does not work for you, you can still copy them back to the folder. You can find out your username by doing a Ctrl-Alt-Del. If somehow you cannot find the folder, you are probably in the wrong user directory.

4.Launch iTunes and put your iPhone in recovery mode. Refer to this article on Unable To Restore iPhone on how to do put iPhone in recovery mode.

5.Proceed with restore and iTunes will download the update online. If you are downgrading to a lower version, do step 3 and leaving only the firmware file that you want to downgrade to. Double click on the file and iTunes will begin the restore.
