What generation - which firmware? And other questions

[utnalove]

Hi all...

1) I have an iPod Touch 8GB... I think it's the 2G, because iTunes offers the 4.0.2 firmware to upgrade... am I right?

2) The latest jailbreakable FW is 4.0.1. Here I can see only the 4.0. Is there somewhere the 4.0.1 to download?

3) Why in the URL of the 4.0 for iPod touch 2G there is "iPhone" in the URL "http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone4/061-7435.20100621.tr49t/iPod2,1_4.0_8A293_Restore.ipsw" - is it for sure the correct firmware?


4) When should I update the firmware with the "restore" firmware, or the "normal" firmware? What are the differences?



Thank you

Youll need SHSHs to restore to it. If its an MB model you can use a custom fw by Sn0wbreeze (PC) or PwnageTool (Mac). If its an MC model and you dont have SHSHs you cant restore to 4.0.

What is SHSH? Any guide? Isn't it as simple as:

-download the FW
-click on "shift" while restoring or updating via iTunes?


How to know if it is a MB model???

[i.Annie]

Its not that simple anymore especially on iOS 4. you check the model number on your iPod box or in settings>general>about

If you didnt save your SHSHs before 08/19 then you probably dont have them.

SHSHs are needed to restore on cuz Apple stopped signing 4.0 and 4.0.1 for certain devices, including iPT 2G.

You can get TinyUmbrella to check if there are any saved by any chance.

This is what I read:

version 3.1.3 (7E18), model MC086LL

If I can't restore to 4, can I upgrade the firmware to a brand new 4?

Or maybe it's better if I upgrade via iTunes to 4.0.2 and then wait for the jailbreak? What can I do?

[i.Annie]

You can try restoring to any of the 4.0 or 4.0.1 without SHSHs as Im not sure if Apple has stopped signing for iPT 2G yet. If the restore fails then youll need the SHSHs. Being an MC model you cant use custom firmwares. You also cannot ugrade to 4.0.2 as the only jailbreak for 4.0.2 is Redsn0w which only works with MB models and iPhone 3G.

[utnalove]

If it fails, when it should fail? In the very beginning or it will be unusable? [in other words what can happen "bad"?]

Where can I find the 4.0.1 to download (not 4.0.0)?

Is there a procedure for this "restore"?

The worst that can happen is you can get stuck with the "Connect to iTunes" sign. If this happens, go to ih8sn0w.com and download iReb. There should be a "Recovery mode loop fixer" make sure you read all the pop-up windows. And select iPod touch 2g. You will then be back to where you started before the restore.
