No jailbreak with 3GS (3.1.2) using PwnageTool 3.1.4
So now we have got the new iPhone 3GS, brandnew out of the box. The Software Version is 3.1.2 according to iTunes version 9.0.2 (running on a MacBook Pro).
I surfed the net for a good way to jailbreak the device and ended up with PwnageTool. I used PwngTool 3.1.4 and tried to jailbreak (don't need to unlock). To create the custom ipsw file I used FW 3.1.2 for the 3GS named iPhone2,1_3.1.2_7D11_Restore.ipsw But somehow one of two things happened:
Either (after creating the custom restore ipsw) iTunes would give me this annoying 160X error message (although Pwnage had put the phone into DFU mode), when I tried to restore it with the custom file.
Or (and this is a tragedy) it all seemed to go well, the custom file was installed but then, when it should come back into normal mode so that I could restore it with my backup, the screen turned black and iTunes reported, that the phone was connected in (in German) Wartungszustand - I guess that would be translated "service-mode" and it means, that it still was in DFU mode. So I had to do another Restore!
I only could get out of DFU mode by Restoring it using the original ipsw directly from apple through iTunes.
I read some more information on the Dev-Team blog where someone said, that iHelper has to be killed so I rebooted every device, I killed iHelper and so forth. All that did not help, the same problems occured.
Does anybody know, what the problem is or can anyone help me out on that?
Apreciate any suggestions!
Re: No jailbreak with 3GS (3.1.2) using PwnageTool 3.1.4
Thank you for your post. You were right, the bootrom is iBoot 359.3.2
Find your bootrom version using this post.. http://www.hackint0sh.org/468379-post24.htm
no jailbreaking is required to get this information.
I suspect (because your iPhone is new and based on your description) that you have iBoot-359.3.2
The only jailbreak supported on iBoot-359.3.2 is blackra1n RC3. Pwnagetool does not yet work with this bootrom version.
Now I do have one more question: when I tried to jailbreak the phone one of the failures, that occured was that the phone stuck in DFU mode after restoring the custom ipsw. iTunes would not let me install my backup. What I didn't know then is, how to kick the phone out of DFU mode. What would happen, if I went through the process again and then at simply kick it out of DFU mode - would the custom ipsw be installed and would that work, or should I leave it and wait until someone solves that problem?/QUOTE]
Custom ipsw will not work on your iPhone end of story.
Put your iPhone into dfu and restore it with original 3.1.2 ipsw. That should mostly work.
Then jailbreak with blackra1n if you want to.
