How to Fix iPhone after having installed the Siri GUI from SiriN1ght

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:(

How to Downgrade iPhone 3GS from iOS 5 beta 7 to 4.3.3 without having saved SHSH blobs

REQUIREMENTS:

  • Firmware 4.3.3 for iPhone 3GS which you can download here
  • Tiny Umbrella version 5.00.11 which you can get here
  • Redsn0w 0.9.6rc16 which you can get from here (for Windows) and from here (for Mac)
  • iTunes 10.5 beta 8 which you can get from here
  • Sn0wbreeze 2.7.3 for Windows and Pwnage Tool 4.3.3 for Mac

Once all these files are downloaded (or installed) we can begin.

WARNING: I am not responsible for any damage done to your phone due to unforeseen and uncalled for side-effects and results. Proceed at your own risk.

  1. First of all make sure your iPhone is running 5.0 beta 7 with the iPad baseband 06.15.00. Open up Tiny Umbrella (Wait for it to load) and click on “Start TSS Server”. Now open up Snowbreeze (or Pwnagetool) and follow the instructions to create a custom 4.3.3 IPSW. Now put your iPhone in DFU mode by following the on-screen instructions.
  2. Now iTunes should now open-up telling you that it has discovered an iPhone in recovery mode. (Tiny Umbrella should still be open running the TSS Server). Click on Restore while holding the shift key (on Windows) and alt-option key (on Mac). Find the custom 4.3.3 ipsw you created (usually on desktop) and click on it. Now don’t do anything rash and wait for iTunes to restore your Phone.
  3. Now your iPhone should boot-up in recovery mode (black screen) and the same message about iTunes finding an iPhone in recovery mode… Ignore it and now launch Tiny Umbrella, stop TSS server and click on “Fix Recovery”. After about a minute your screen should now have something about Greenpois0n. Hold the Power and Home button until the screen goes black then release both buttons.
  4. Now launch Redsn0w and point it to the original 4.3.3 IPSW (the one from Apple). After the verification process, uncheck install Cydia and just click on install iPad baseband. Now click finish, and wait for the process to finish.
  5. Now relaunch Redsn0w and this time check install Cydia. Wait for process to finish. Now we are almost done
  6. Launch Cydia on your iPhone 3GS and install Ultrasn0w.

And voila! There you have it:) A downgraded fully working iPhone 3GS running 4.3.3! Feel free to comment, contact me or ask any questions:)
