Downgrade iOS 4.1 to iOS 4.0 on iPhone and iPod touch

Here is the rewritten text in a well-structured format suitable for a web page:

**Jailbreaking Your iPhone 2G**

So, you have an iPhone 2G and you want to jailbreak it. Don't worry, I'm here to guide you through the process.

First, go through your device and pick out whatever version of iOS you're currently running - in this case, I'll be using 4.0.2 as an example.

To start, let's say you have 4.0.2, so now we hit save on my shsh. This will give it just a minute to check if Cydia has the latest version of the firmware for your device.

If Cydia does have the latest version, it'll download and you're all set! But if not, don't worry, just go back and find a different version of the firmware - for example, 4.0 or 4.1 - until Cydia has saved that blob for you.

Now, I know some of you guys might be thinking this can be a bit complicated, but trust me, it's not that big of a deal. Just pick out your device and then go ahead and go to the firmware version you were last jailbroken on.

For most of you, this will be 4.0 or 4.1, so just pick those versions and there's a pretty good chance Cydia will have them.

To make sure all you need to do is come over here to Display SHSHs and then after you're done saving it should pop up saying "You saved..." whatever version you just saved.

As soon as you're done with that, we're pretty much done! All you need to do is click Start TSS Server, which will get your device all set up for jailbreaking.

Now, go ahead and open up iTunes on your computer - make sure your device is still plugged in. You should see a screen telling you everything about it.

At this point, it's very simple: just go ahead and restore to whatever firmware version you have the SHSH for.

To do this, with a Mac, hold down the Option key while clicking Restore. With a Windows computer, hold down the Shift key and hit Restore. I'll be using the latter method since we're going to open up iTunes to pick out our own firmware.

So let's go ahead and restore to 4.0.2. Click Open and then hit Restore. This will just give it a minute to load.

And that's it! Your device should now be jailbroken in no time.

**Note:** I'll be back after this minute-long pause to complete the guide.

As soon as my device finishes loading, I'll take you through the rest of the process.

Okay, guys! My device is all loaded up. To finish the guide, I just need to restore my device using iTunes and then click Restore on the new firmware version I downloaded earlier.

This will fix any issues or errors that might have popped up during the jailbreaking process, so don't worry about it!

And there you have it! After 15 minutes of syncing all my stuff over, my iPhone 2G is now completely jailbroken using Cydia.

**Downloading Firmware Files**

Unfortunately, I didn't have time to show how to download the actual firmware files earlier. To do this, just Google whatever version of iOS you need - in this case, if you need iPhone 2G running 4.0.2, Google "iPhone 2G 4.0.2" and it'll come up with a list of links for you to download the firmware.

It's very simple, guys! Just Google what you need, and voilà!

**Future Jailbreaks**

Don't worry if you're still on 4.1 forever - there will be jailbreaks for future versions of iOS in the near future. Maybe it'll even be available within a little while, so you won't be stuck on 4.1 forever.

And that's it! I hope this guide helped you out, guys. Thanks for watching!

WEBVTTKind: captionsLanguage: enhey guys so today i'm here with a tutorial showing you how to downgrade the firmware on your ipod touch your iphone as well as on your ipad so guys this is a very very simple tutorial process shouldn't take you any time at all it's very very simple um but i've had a ton of requests a lot of people asking how to do it so i'm going to show you um before we do begin however there's just one thing i do want to mention now to do this you will have either needed to save your sh sh blobs manually in the past so basically if maybe if you use firmware umbrella or something similar if you already have your shsh blob saved on the computer so if you have that you're all set um otherwise you will have had to have jailbroken on some earlier version of ios so odds are if you've jailbroken city went ahead if you hit the make my life easier button when you first got the city and you first jailbroke odds are that city already has your shsh blog so guys i'm gonna go ahead and show you how to do both methods both is very simple and if you're not sure if city did save it again i'll show you how to even check for that too so let's go ahead and show you how to do it okay so to begin with all we need to do is download a very simple program called the firmware umbrella i'm a big fan of this program it's very lightweight you don't need to install anything and works really quite well so let's go ahead and show you how it works um so to begin with let's go ahead and just download it just come to the firmware umbrella.blogspot.com and of course we'll have the link to in the description right below this video so just come right down here and there are some links right here on the right side so you can go ahead and download for mac windows as well as linux so go ahead and just uh download it to whatever you want and then let's go ahead and show you how it works okay so now that you have the program go ahead and just open it up and plug in your ipod iphone or ipad whatever you're looking to downgrade okay so this is a very simple process let me just go ahead and walk you through it basically there are two different ways now if you've used this program before and you've already saved your sh sh blobs then it should be no problem all you do is just to make sure that you know what you have just click display shshs okay so as you can see here these are the ones i already have on my computer so odds are if you've if you've used this program before you'll at least see a couple of firmwares in here so for example i can safely downgrade to any of these no problem okay now if you've never used this program before this will be blank so it's no big deal okay so now let's say let me go ahead and pick something random let's say you're you have an iphone 3gs um and the last time you jailbroke was on ios4 just just 4.0 okay so to go ahead and check all you need to do is click advanced options then it's request version okay so all you need to do is just go through here and pick out whatever device you have with ipad iphone whatever so of course i do have the iphone 2g and then i can go ahead and just look through here and the last time i was jailbroken was on 4.0 and 4.0.2 so basically what you do is let's say you have 4.0.2 so now you hit save my shsh and it will go ahead and give it just a minute and it will check city if it has it now if it does it will download and you'll be all set if it doesn't for whatever reason all you do is just go back and find a different version of the firmware so example 4.0 and see and keep going until cydia has saved that blob so i know guys this can be a little bit complicated and i know this is where a lot of you guys do run into trouble but it's not that big a deal just go ahead pick out your device and then go ahead and go to whatever firmware you were last jailbroken on so like i said odds are most of you guys it's going to be 4.0 or 4.0.1 so just pick out that firmware and there's a pretty good chance that cydia will have it and to make sure all you need to do is come over here to display sh shs and then after you're done saving it should pop up saying you know 4.0 or whatever you just saved okay so as soon as you're done with that then we're pretty much done so all you need to do is just come over here click start tss server so as soon as you've done this you're all set up to go ahead and restore your device to whatever sort of firmware that you're looking for okay so now all you need to do is just go ahead and open up itunes so obviously with your device still plugged in uh you should get the screen now telling you everything about it so at this point it's very very simple all you need to do is go ahead and restore to whatever firmware that you have the shsh so for this example i'm going to go ahead and pick 4.0.2 although obviously what for whatever you downloaded you'll have that so with a mac you go ahead and hit option and you hold you hold the option key and click and left click restore for a windows computer you hold the shift key and hit restore so i'm going to do this instead of just restoring it automatically we'll go ahead and open up a thing so you can pick out your own firmware so let's go ahead and go through here and pick the four points there we go 4.0.2 so go ahead and click open and now it'll go ahead and just go ahead and just hit restore so now as you can see here it will give just a minute and then actually instead of asking apple if that's okay to do it it'll use tiny umbrella so instead of you know having any issues or any errors it should work just fine so hang on go ahead and give this a minute to go ahead and load and i'll be right back as soon as it's done so there you go guys i took about you know 10 15 minutes to go ahead and sync all my stuff over but after that no problem at all so guys hopefully that helped you out um now about the only thing i was not able to show is downloading the actual firmware files um now for that it's very very simple just go ahead and google whatever you need so you know you need ipod touch second generation 4.0.2 whatever you need you can go ahead and just uh just google it and it'll be no big deal so guys i hope this helped you out um and of course if you're still on 4.1 forever and you were not able to go ahead and do this maybe your city didn't have your sh sh blobs or you've never jailbroken before don't worry there will be a 4.1 jailbreak in the fairly near future maybe you know it within it was in a little while so you know you're not going to be stuck on 4.1 and not being able to jailbreak forever so anyway guys thanks for watching youhey guys so today i'm here with a tutorial showing you how to downgrade the firmware on your ipod touch your iphone as
