Apple Complete iOS Jailbreak Guide

[metamaster]

If you shift-click update, you shouldn't lose anything, although it can happen (unlikely).

I need some help, every time I do the restores it gives me an error 3194

That error means Apple isn't giving out SHSHs that particular firmware. Unless the SHSHs were saved with Cydia/TinyUmbrella, you're out of luck with using that firmware. (With newer devices, you can definitely get a tethered 4.2.1 jailbreak though.)

Guys.

I did it.

I FINALLY made the redsn0w video.

But I majorly screwed up in music and forgetting to do something.
Here is the video for now. http://www.youtube.com/watch?v=Old3X1X0n2o

But I'll fix it tomorrow(or when I get around to it, probably tomorrow)

Nice vid.

Just maybe zoom in a bit more to the monitor?

Quick question, on an Ipod touch 2g MC model, would it be a tethered or untethered jailbreak through the most recent redsn0w, 0.9.6b4?

Thanks.

EDIT: Grammar

 

[metamaster]

Tethered. If you have 4.2b3 SHSH blobs you will be able to untether it with the official release of redsn0w 0.9.7.

 

[Dialexio]

The last version of redsn0w to support the iPod touch 2G with the new bootrom was 0.9.6b1 (even then, it was tethered). I suggest using greenpois0n to jailbreak your iPod on 4.1. (To my knowledge, Apple's still signing 4.1 for the iPod touch 2G.

)

4.2.1 doesn't contain much over 4.1 for the iPod touch 2G, other than breaking the app switcher (can be fixed with a hacky capabilities change) and blocking the exploit used for an untethered jailbreak on newer devices.

When you mean still signing...do you mean I could maybe jump from 3.1.3 to 4.1? Through Itunes or something? Sort of like restoring a certain ipsw? And then jailbreak? Clearly I'm sort of a noob this...thanks for the suggestion...

You can do that with Tiny Umbrella. First, download it, then run it with your device plugged in and save it's SHSH blobs. If it saved your 4.1 blobs, you can upgrade straight to it. Press start TSS server and open iTunes. Download the firmware file you need (google it) and go to devices in iTunes. Shift-click update and select the firmware file you downloaded when prompted. Let iTunes update your iPod (it could fail, although it is unlikely) and then you are ready to jailbreak. Look at the beginning of this topic to see how (with either Greenpois0n or Limera1n).

Edit: @Dialexio: You can also mention this in your guide: You can update to an older firmware without restoring while using Tiny Umbrella.

By saying that it sounds like it should already be on 4.1...to be able to save "my 4.1 blobs," but I'm on IOS 3.1.3 on a 2g Ipod Touch MC Model....or am I wrong? I have the 4.1 ipsw file for my Ipod...but can I do anything with it? Like what you mentioned in your post?...

Or am I completely and utterly wrong? o.o
Thanks for the input btw,

EDIT: Extra info...

You don't need to be on a specific firmware to save it's SHSH blobs. When you open Cydia for the first time, it asks you if you want to let it make your life easier by letting it save you SHSH blobs automatically.
That way, when a new firmware comes out, Cydia tries to save them without your input. But you can also save them to your computer yourself with Tiny Umbrella (Cydia saves them to Saurik's server). Dialexio said Apple might be still be signing them, so you can save them yourself, therefor you would be able to upgrade to a firmware that isn't the current one.

Great guide, just wish I wasnt on 4.2.1 with hackintosh not being an option

Mmmm, icic. See that's the thing...I kinda need to restore/update my Ipod...I need it to be a "clean slate" so to speak, but still be able to re-jailbreak it. I was able to open Cydia and install some apps after I jailbroke it with a patched version of Spirit...but I could never open it again after...it crashes every time I try to open it up, Cydia, ...And I'm pretty sure I didn't save my blobs...stupid I know...or at least I don't think I did... :/

And in my case I can't really restore because my iOS isn't being supported anymore, and 4.2.1 has a tethered/beta jailbreak...so I wanted to see if there was a way to get iOS 4.1 on my Ipod, thus "virignizing" it and being able to re-jailbreak it with a more properly working Cydia...

Thanks again for the input

and sorry for the long message...

You can restore to 4.1 instead of updating, which will erase everything. If you want to go to a firmware that Apple isn't signing anymore, you need to use Tiny Umbrella, otherwise you won't be able too (you can also use it to check to what firmwares you can downgrade too). Technically, if Apple is still signing 4.1 blobs, you should be able to restore to it without Tiny Umbrella.
Are you sure you used Spirit to jailbreak before? What you described sounds a lot like a tethered jailbreak (Blackra1n).

Mmmhmm, I did. I was able to retrieve the 4.0-4.2.1 blobs. And through that I restored/updated to 4.1
All was going well until I tried jailbreaking through greenp0ison...I followed the instructions and was able to get Loader installed...but I didn't bother to respring to get the icon looking right...should I have? because right after I just installed Cydia and that icon is also white and now it won't load either...wth...

 

[metamaster]

The respring was optional by the way, since some people don't even keep the loader app. Try restarting your iPod and opening Cydia again. But what exactly do you mean by it won't load? It crashes or it's reloading...?

Yea, it would "auto-crash." I touch the Cydia icon and it goes to a screen as if it were to start loading....but then crash back to the springboard...

EDIT: Should I restore again? And try jailbreaking again or something after? Once Cydia is installed I can't use Loader to install it again right? As if I were to overwrite it or something? And yes, I have tried restarting my ipod and then opening Cydia again...cydia still has the blank white icon...and will "auto-crash," I have a feeling the Cydia icon shouldn't be white though....

Did you use a backup in iTunes after you restored your iPod? I've heard that the contents of one can affect Cydia. if you did use one, you can try restoring again and setting up your iPod as a new device.

Yea, I set it up as a new device...should I try restoring again regardless and try jailbreaking again?

 

[metamaster]

Yeah sure, what do you have to lose. But this time, try jailbreaking with Limera1n. And if that fails too, try going to 4.0 and using Star (since you said you had SHSH blobs for that firmware). But something tells me it's not the jailbreak, but something with your iPod... A restore usually wipes out everything.
