[How-To] Using tiny umbrella to update/downgrade/restore

This guide is for people wanting to use tiny umbrella to restore to firmwares Apple is no longer signing.

Currently Apple is signing: 5.0.1 and 4.1(3G/3GS only for 4.1)


Using tiny umbrella is mainly for iPhone 3GS/4, ipod touch 3G, and iPad since you do not need SHSH for previous devices (although there is a soft SHSH being done on iPhone 3G for 4.0 and up firmwares now but that can be easily avoided by using redsn0w then pwnage tool). For this to work you NEED to have your SHSH for the firmware you are trying to restore to. If you do not then tiny umbrella will not help you restore to that firmware.
If you have never saved your SHSH before just give tiny umbrella a try, you may find you have SHSH after all, it doesn't hurt to check


A new version of tiny umbrella is available from the link below. The developer has added a lot of new features and overhauled the UI. Click the link to check the changes and get the latest version. You can also read about the changes here: Jailbreak Utility TinyUmbrella Gets Big Update


Also for anyone looking to use tiny umbrella to preserve baseband, that feature only works on iPhone 4. It cannot preserve baseband for iPhone 3G/3GS. Use pwnage tool or sn0wbreeze for them.

If you are trying to preserve baseband on iPhone 4 going to 4.2.1 see here: https://twitter.com/#!/notcom/status/33338499377659904

1. Do a backup in iTunes first.

2. Download the latest tiny umbrella from: The Firmware Umbrella . I would recommend you reading what the developer has written on there and in his readme file about his tool. It is very informative and he explains what is going on and any errors that you may come across when using tiny umbrella.

3. Run tiny umbrella (on windows right click then choose run as administrator). Tiny umbrella will not show your SHSH automatically, you have to download them from cydia first. To do this click "Save my SHSH", this will download all available SHSH for your device from cydia. You should save your SHSH twice, once with the box under advanced that says "Request SHSH from cydia" checked and once with it unchecked. If you never used tiny umbrella when apple was signing that specific firmware or pressed the "make my life easier" button in cydia then it may come back with an error saying there is no SHSH, if that is the case I am sorry but that means that you will not be able to restore to that firmware. You can check what SHSH you have on file with cydia by opening cydia, the first page at the top will tell you what firmwares your device can restore to. As far as SHSH go it does not matter what firmware is on the device itself. It only matters as to what firmware apple was still signing at the time you pressed “make my life easier” in cydia or saved your SHSH with tiny umbrella. Even if you are still on 3.1.3 you cannot get your SHSH now since Apple is not signing that firmware anymore. Likewise even if you are on 3.1.3 you can get your SHSH for the current firmware now since that is the firmware Apple is currently signing.
 4. To restore simply press “Start TSS Server” then open itunes, hold down shift(windows) or option(mac) then press restore (tiny umbrella only supports restore not update). A window will open where you can choose the firmware that you want to restore to. You can download firmwares from here: IPhone Firmware Download Links - ModMyi - Wiki or here iPod, iPhone and iPad Firmware Download
It is best to use a browser like firefox to download the file as other browsers may download it as a .zip file when it is supposed to be .ispw. If that happens simply rename the extension from .zip to .ipsw. Firefox and other browsers do not have this issue. Also if you get a 3002 error put the iphone in dfu mode first then try the restore. To put it in dfu mode: plug in the iphone, then hold the power button and home button together for exactly 10 seconds, then release the power button while continuing to hold the home for an additional 10 seconds or until your computer and itunes recognizes it. iTunes will see it as being in restore mode, the screen of the iphone should be all black.
5. If near the end of the restore process you get error 1004 or 1015 do not panic it is expected. Just use the “Exit recovery” button if you restored to firmware 4.1 or lower or use the "Fix Recovery" button for firmware 4.2.1 or higher, and your device should boot up. If that doesn’t work you can download recboot from here to boot your device: Fix iPhone Recovery Mode Loop - Works On iPhone 4 & Windows 7



 If you are unable to get out of recovery with tiny umbrella's "exit recovery" or "fix recovery" then I suggest restoring to custom firmware made with pwnage tool or snowbreeze to get around error 1004/1013/1015.

6. From here you should be good to use your jailbreak of choice. There is a link below that can tell you what options you have to jailbreak depending on what firmware and what device you are on.

Troubleshooting:

Tiny umbrella seems to sometimes have issues on windows 64-bit so if you are getting unexplained errors, try a different computer that has windows 32-bit or use a Mac.

If you are getting error 13 it is because you don't have at least itunes 9.2 installed. iTunes 10 will also work just fine for this guide.

Tiny umbrella needs port 80 to work, skype uses port 80 which can cause some problems. So close skype when using Tiny Umbrella (Thanks packman911 for the info)

To check what other things might be using port 80 go here: How to Check and Identify Which Application is Listening or Opening Port 80 and 443 on Windows My Digital Life if you find other things running that are using port 80 close those processes for now in task manager then try running the tiny umbrella server again and restoring. The newer versions of tiny umbrella will actually tell you when you open it if there is something blocking port 80.

If you are having trouble using tiny umbrella's TSS server to restore you can always just click on advanced, select the box that says "set hosts to cydia on exit" and then close tiny umbrella. This will set your hosts to cydia so that itunes will get your SHSH from there allowing you to restore to a firmware that you have SHSH for.
