Well guys I finally figured out how to downgrade from iOS 5.0.1 to 5.0. on my 3Gs. I don’t know if this method works on other models but its worth a try.
Remember: I cannot be held responsible for any software or hardware damage done to your phone by following this tutorial. Continue at your own risk
Now that the legal stuff is out of the way (and you’re willing to continue) you’ll need:
The latest version of Tiny Umbrella v5.01
A custom 4.3.3 IPSW
Stock 5.0 IPSW
The latest version of iTunes
The latest version of Redsn0w
First of all, open Tiny Umbrella and start the TSS server. Then open up Redsn0w, click on “Extras” and click on the button that says something like “…to restore to a custom IPSW” Follow the on-screen instructions… Now open-up iTunes and after putting your phone in DFU mode Restore to custom 4.3.3. Now update your phone to iOS via my previous tutorial… Now you have a jailbroken version of iOS 5:)
If you’ve recently updated and jailbroken your iPhone on iOS 5.0 then you’ve probably noticed that after it being completely drained (2% battery) and shutting down, and you plug it in to power….. the phone opens up to a green screen… Don’t worry (like I did:) ) this is not a big problem. It can easily be fixed.
Just keep your phone plugged in to power and it should boot up to a normal Apple logo. If that doesn’t work hold the Power and Home button until the phone restarts. Well that’s it for today:)
Well you probably got excited at the news that Siri had been ported to the older iPhones and decided to install it on your iPhone… Like me:P You then found out it hadn’t worked and decided to uninstall it… Only to find your iPhone stuck in a boot loop (unending apple logo). Well I finally found a way (after many bruises to my head) to fix it.
Disclaimer: I am not responsible for any damage done to your phone by following this tutorial. Execute the steps at your own risk!
First of all you will need to put your iPhone in DFU mode. That is done by holding the power and home button for about 10 seconds then releasing the power button, keeping the home button pressed for about 15 seconds. You should now be on a black screen.
Plug-in your phone to iTunes 10.5 and click on Restore. Follow the steps and after about an hour or so your phone should now be running 5.0.1
For Jailbreakers: Get the newest Redsn0w from the Dev-Team Blog
Click on “Extras” and point it to the iOS 5.0 IPSW. Now click “Back” then “Jailbreak” and follow the steps shown. You should now be running a tethered jailbreak for all devices except for iPhone 3Gs old-bootrom (untethered)
Well thats it:) If you have any questions or problems feel free to post them in the comment section.
Attention: For the time being, Ultrasn0w won’t work on iOS 5.0.1 even if you have the corresponding baseband:(
If you’re a lucky owner of an iPhone 3Gs (old-bootrom) you can now have access to an untethered jailbreak for iOS 5! Trust me the upgrade is worth it.
To upgrade to iOS 5 you are going to need:
Now plug-in your iPhone, open up Redsn0w. Click on the “Extras” tab then click on “Preserve Baseband with custom IPSW”. Follow the instructions then go back to menu and click on “Jailbreak”. Point Redsn0w to the NO-BB… IPSW and follow the on-screen instructions. After reboot you should now have an iPhone 3Gs jailbroken on iOS 5!
Don’t forget: I AM NOT RESPONSIBLE FOR ANY DAMAGE DONE TO YOUR PHONE DUE TO THE USE OF THIS TUTORIAL!:)
The well-known veteran hacker Muscle Nerd has just released a new version of the jailbreaking tool Redsn0w.

The most notable feature of RedSn0w 0.9.9 beta 1 is the firmware auto-discovery during DFU Mode which makes it possible to jailbreak iPhone, iPad and iPod Touch even without pointing RedSn0w to .IPSW file. So what are the other features of RedSn0w 0.9.9b1?
– Automatically determine which device and Firmware you have
– Fetches pieces of public IPSWs from Apple (once).
– Non-public IPSWs must be provided manually (once).
– It then caches those pieces for future use.
– “Just boot” is a tethered boot.
– Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
– “Pwned DFU” puts your device in a pwned DFU state.
– “Recovery fix” gets past 1015 types of errors (should work on iOS5 beta too)
– “Select IPSW” is for picking non-public IPSWs, or overriding auto-detection
– “SHSH blobs” has a bunch of options.
– “Fetch” – fetch current PARTIAL blobs on device.
– Should complete in under 10 or 15 seconds.
– Puts the set of PARTIAL of blobs on your computer as a plist.
– Checks if Cydia already has a full set for this device and build. If not, it submits this PARTIAL set and returns Cydia’s acknowledgement or rejection
– “Verify” – cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server.
– You can select a whole bunch of blobs to verify at once if you want.
– “Submit” both verifies and submits one or more blob files to Cydia. This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server
– “Query” queries the Cydia server for all available FULL or PARTIAL blobs for a given set of ECIDs
– “Stitch” stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW
WARNING: To my knowledge anything that happens will be an improvement yet I am not responsible for any damage done to your iPhone while using this tutorial.
Hold the power and home button for about 10 seconds. Then release the Power button while keeping the Home button held until the screen stays black. Repeat until desired result. You are now in DFU mode.
Plug your phone in the computer and wait for iTunes to recognize it in recovery.
Press the Shift key (on Windows) or alt-option key (on Mac) and click Restore.
Now find the downloaded IPSW and click on it. Wait for iTunes to do the rest.
Yay! Your iPhone should now be booting up. Now follow this tutorial to learn how to downgrade from iOS beta 7 to 4.3.3
