Sooo...
what had happened today ?
Seriously I feel
BORED
with
iOS4.0.
You know why ?
Lot of thing I still cant do with this firmware..So I've decided to
:::::DOWNGRADE:::::
to
3.1.3 Firmware
which much more easier for me to play around..

Guess what ? Several iPhone 3G users have discovered that iOS 4 makes their iPhone slow down and lag too much. If you are one of the people who have decided that the new iOS 4 features aren’t worth the slower load times and the lag, then here are the steps you need to follow in order to downgrade your iPhone.

Note: The process works the same way on both Windows and the Mac OS X. The only difference between the two is RecBoot. If you are a Windows user, pay close attention to the RecBoot process before diving in. Also, please read through the whole guide before following it, so you have an idea of what to do throughout.
IMPORTANT!!!!!!!
• This guide may not offer consistent results. So please proceed at your own risk. • Do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone 3G.
• This procedure is strictly for iPhone 3G users. Apple has stopped signing the iOS 3.1.3
firmware and hence this guide will not work on iPhone 3GS as Apple has stopped signing the
older iPhone OS 3.1.3 files that is required to restore iPhone 3GS.


Step 1: Download iPhone OS 3.1.3

In all likelihood, users may already have a copy of the older iOS firmware stored on their computer.
If you are a Mac user, navigate to :
:: >> ~/Library/iTunes/iPhone Software Updates and
look out for a file named
iPhone1,1_3.1.3_7E18_Restore.ipsw.



Windows users may check out this file at
::> C: \Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPhone Software Updates.
( Location dependings on the OS that you are using )
Alternately, you download a fresh copy of the iPhone OS 3.1.3 firmware to your computer.
link : ( goolge it !! haha )
Save a copy of this iOS firmware on your computer desktop

Step 2 : Download RecBoot

RecBoot is an important utility that will help
in completing the downgrade process.
Download this tool on the link provided.
Step 3 : Set iPhone To DFU Mode

(a) Plug your iPhone to the computer
(b) Switch OFF the iPhone by pressing the Sleep/Wake button. Swipe across the ‘Slide to Power Off‘ option to turn your iPhone off
(c) With the Sleep/Wake button pressed, press and hold the iPhone Home button for ten seconds.
(d) You can now release the Sleep/Wake button while the Home button is kept in the pressed state.
(e) iTunes will display a window that reads, “iTunes has detected an iPhone in recover mode“. The iPhone screen will now turn black. This indicates that your iPhone is in the DFU mode. Click ‘OK’ to close the iTunes pop-up message.


Step 4: Restore iPhone 3G using iPhone OS 3.1.3 firmware

(a) Under the ‘Devices‘ section on the left pane of iTunes, click on your iPhone device.
(b) Hold the Option(Mac) or Shift(Windows) key down and click on the ‘Restore‘ button
(c) Navigate to the computer desktop and click on the downloaded iPhone OS 3.1.3 firmware to restore.
(d) iTunes will now begin the restoration process. This process will take close to 10 minutes or more for completion.


(e) iTunes might throw 1011, 1013 or 1015 error as seen below. You don’t have to panic. It’s normal, just ignore this error as the firmware has been successfully installed on your iPhone 3G. You need to use RecBoot utility to exit out of recovery mode.



Step 5: Exiting Recovery Mode

For Mac users:Navigate to your computer desktop and launch RecBoot. Click ‘Exit Recovery Mode‘. This will reboot the iPhone to the newly downgraded iPhone OS 3.1.3.

For Windows users:
(a) You may require .NET 4.0 firmware for the application to work.
( Can be found on Microsoft Official sites )
(b) Navigate to the desktop. Right click on RecBoot and choose Properties -> Compatibility
-> Run this program in compatibility mode -> Windows XP. You may skip this step if you are already on a Windows XP platform.
(d) From the computer desktop, launch RecBoot. Select the ‘Exit Recovery Mode‘ option. This will reboot your iPhone to the downgraded iOS 3.1.3 platform.
Step 6: Restoring Backup
iTunes will now prompt you to set up your iPhone. You can restore from a backup that you had created before upgrading to iOS 4 to sync your apps and data or set it up as a new iPhone.
Please note that it is only possible to sync with a pre-4.0 backup. Any backup file created after upgrading to iOS 4 might not be supported.
( I've tried mine but doesnt work.. )
