How to Downgrade to iOS 4 from iOS 5 using TinyUmbrella?

By on June 28, 2011 in Apple with 1 Comment

When the iOS 5 Beta version was released for the developers to test their apps on many of the non Developers like us have gone and upgraded to iOS 5 Beta using some tweak.

iOS 5 usage was such a pleasure but after sometime when you realize that you are not able to get network connection which makes it a big minus point of the Beta Version, that is when you change your mind to get back to the previous version of the iOS that is the iOS 4 which is nearly impossible if you want to do it the official way.

iTunes 10.5 beta – which can be available here at Apple iTunes 10.5 beta
Apple iphone running on iOS 5Beta
iOS 4 Firmware for your iPhone or iPad or iTouch which can be available at Firmware Files Download
You also Need TinyUmbrella Software:
TinyUmbrella For Mac
TinyUmbrella For Windows
Mac or a Windows PC

The Downgrade at a brief glance:
1. Check that you are on iOS 5 and that you have installed iTunes 10.5 beta
2. Backup your data.
3. Put your iPhone into DFU
4. Remove any previously made host file changes (manually or with TinyUmbrella).
5. Restore through iTunes 10.5 beta to iOS 4.3.3

For Windows PC users i think TinyUmbrella is the only way till date which will sicessfully downgrade your iOS to 4 from iOS 5 beta, where as XCode can be used to downgrade your iOS device with Mac

Steps to Downgrade from iOS 5 to iOS 4 using TinyUmbrella:

Note: This process should be started without connecting your iPhone iPad or iTouch to your Mac or Windows PC.

  • Install iTunes 10.5 Beta on your Mac or Windows PC
  • Install TinyUmbrella on your Mac or Windows PC
  • After TinyUmbrella is installed, you have to launch this software and you will be able to see an options “Advanced” on which you have to ‘Click’
  • Uncheck the box that says “Set Host to Cydia On Exit” This will change your settings, so better be Unchecked before anything happens.
  • Shut Down your computer Windows PC or Mac
  • Connect your Device – Make sure that you connect your device to your computer before it restarts
  • Now Restart you Computer Windows PC or Mac
  • After you have started your computer you need to launch iTunes with your iOS device already connected to it.
  • There will be a box opening which will be showing an error message which you should be Ignored
  • Next you have to put your device into “DFU mode”

How to put iPhone or into DFU Mode:

  1. Plug your iPhone, iPod touch, or iPad into your Mac or Windows PC and make sure iTunes is running.
  2. Hold down both the Sleep Button (on top of your device) and the Home Button (on the front underneath the screen).
  3. Keep them both held down from about 10 seconds. (If you see the Apple logo, you’ve held them too long and will need to start again.)
  4. Let go of the Sleep Button but keep holding the Home Button for about 5 seconds. (If you see the “Plus into iTunes” screen than you held it too long and will need to start again.)
  5. If the screen stays black, that’s it! Your iPhone, iPod touch, or iPad should now be in DFU mode.

  • Once you have successfully put your device into DFU mode go to iTunes which will be showing you a Error message in a box stating ” A device has been found in recovery mode” which has to be restored.
  • Now you can happily restore your device to your desired iOS 4 firmware which you have downloaded earlier.

This is a very simple way to downgrade your iOS software, and i think its the only way to downgrade your device if you are a Windows user and you don’t have access to  a Mac
