Downgrading is my choice!

14 Jul

After the the release of iOS4, I got carried away in excitement and updated my iPhone 3G’s firmware. Like this was not bad enough, I jailbroke it and was very proud of multi-tasking and etc on my 3G. FAILURE!

It was the biggest mistake ever. I thought I could deal with the waiting time (approx. 7 – 8 secs just to load messages) but eventually, I threw in the towel and downgraded to iOS3.1.3.

It’s WIP now, syncing apps and what-nots. Unfortunately, it wasn’t exactly easy as I had issues with getting out of the recovery mode. So I am going to share with you what worked for me and please note, I am using a Windows Vista machine.

Hope it does the magic for you too 🙂

Step 1:

Download the 3.1.3 IPSW file from here >> iPhone1,2_3.1.3_7E18_Restore.ipsw

After this download iReb from http://ih8sn0w.com/index.php/welcome.snow

Step 2:

  1. Plug in your iPhone.
  2. Power it down by holding the power button and sliding to power off.
  3. Once it’s powered down, press and hold both the power button and the home button for ten seconds.
  4. After ten seconds, release the power button but continue holding down the home button.
  5. If you did it right, iTunes will pop up a window telling you that it’s detected an iPhone in recovery mode and your iPhone’s screen will be black. If it didn’t work, start from the beginning and try again.

Step 3:

Discard the alert that you’re in recovery mode. Click on the iPhone under Devices sidebar in iTunes -> hold Shift -> click the Restore button (if you’re on OS X, Alt/Opt+Click). A pop-up a window prompting you to choose a file appears. Browse and locate the 3.1.3 IPSW you downloaded in step 1. Select that file, and iTunes will start the OS restore process. Expect this to take around 10 minutes or so.

After it’s done, you may get an error message (error 1015) and your iPhone will boot up with a “Connect to iTunes” screen. Run iReb, to remove Recovery Mode loop (you need LibUSB to run this so follow the step-by-step instructions very very carefully esp if you are using Win Vista or 7 as I got stuck here sooo many times and ended up all my USB ports were not functioning). In a few seconds, iReb would help you out of plug-me-into-iTunes recovery mode and you’ll boot right into your freshly downgraded 3.1.3.

Step 4:

Your installation process ends here. If you have kept your back ups of 3.1.3 then you may restore them (you will not be able to restore if your back-ups are for 4.0) and your old apps and stuff will come to life otherwise you got to start from a clean slate and sync the whole lot just like what I am doing this very moment!
