Apple, two days ago, released iOS 5 beta 7 along with iTunes 10.5 beta 7 to developers and earlier yesterday we’ve showed you an exclusive guide to install iOS 5 beta 7 without developer account or registered UDID. In case you got iOS 5 beta 7 on your device, you got some problems and you want to downgrade back to iOS 4.3.5 or iOS 4.3.3, here’s a guide for you.

You may downgrade because of the tethered jailbreak on iOS beta 7 which is untethered on iOS 4.3.3. Since iOS 5 is still in beta releases, it might have some issues so you would like to downgrade.

Downgrade iOS beta 7 to iOS 4.3.5:

STEP 1: Download and install iTunes 10.5 Beta 7 on your Windows or Mac computer.

STEP 2: Download the iOS 4.3.5 IPSW.

STEP 3: Now Put your iPhone, iPad or iPod Touch in DFU mode and you’ll get the Recovery mode message.

STEP 4: Press Shift+Restore (Windows) or Option+Restore (Mac) in iTunes and point iTunes to iOS 4.3.5.

STEP 5: Apple will automatically install iOS 4.3.5 on your iOS device without need to change anything in host file as it’s the latest public firmware.

Downgrade iOS 5 beta 7 to iOS 4.3.3:

You’ll need:

• iOS 4.3.3 firmware IPSW can be found here.
• TinyUmbrella can be found here.
• Recboot can be found here.

STEP 1: Run TinyUmbrella you downloaded above and click on the “Start TSS Server” Button.

STEP 2: Now put your device in DFU mode following these steps:

• Turn off your iPhone.
• Hold the power button for 3 seconds.
• Without releasing the power button, press the home button. Now wait 10 seconds.
• Release the power button and hold the home button until your PC detects the phone. It takes up to 30 seconds.

STEP 3: Now open iTunes and you’ll get the following message which indicates your device in Recovery mode.

STEP 4: Press Shift+Restore (Windows) or Option+Restore (Mac) in iTunes and point iTunes to iOS 4.3.3.

STEP 5: After the restore is done, you may get some errors; just ignore them all. Now you’ll have to get out of Recovery mode. Use Recboot you downloaded above and then press the exit recovery button to kick your phone out of recovery mode.
