jailbreak for 3.1.3(new bootrom)

I guess I'm just another one who inadvertently made my iphone 3.1.3.
There is all that hype about jailbreaking iPhone, using with different carrier and that jailbraking/unlocking is easy. And quite market has been build around it!
As I find out now all that relies on two group of hackers which gives the tools for free, wow!
Now back to details new PwnageTool can jailbreak 3.1.3. Can I use other tool to unlock it? I think the other tool said it can jailbreak/unlock 3.1.3 only if it had old bootrom or it was previously jaibroken. Or unlocking/jailbraking goes together?
 
Actually, my idea has more long term implications:

If a way to do this was found, it would eliminate the problem for all future releases. Those who accidentally, by nececcity, or by purchase of a new phone who found themselves with a new, unjailbreakabe version, could always go back to a "working" version until the new version was cracked. It would also stop the whining!

First of all, there's very little chance a new jailbreak or unlock will be released for 3.1.3, so there's no "INSTEAD of" situation to speak of here.

Secondly, what you suggest would likely require hacking iTunes rather than the iPhone. I'm no pro, so I can't speak to the specifics of this, but it seems to me that a group of people who have spent years mucking about the innards of the iPhone are probably more familiar with the iPhone than the inner workings of iTunes, and so it makes sense for them to continue their efforts on the iPhone side of things. Would you ask an accountant to fix your car?

And last, it seems kind of silly to waste hours of (volunteer!) time to help people downgrade from one minor update when we'll likely be seeing iPhone OS 4.0 in the near future, and that will require a whole new round of jailbreaking efforts.

Oh, I'm not denying that it would have great results! And it would definitely solve the whining ;) I'm just guessing that the guys in charge of such things probably see it as more trouble than it's worth, or else we would have seen/heard something like this by now.
 
does each iphone hs its own SSSH file?can i use the file of some others person ipon in order to restore my baseband and fw back to the unlocked one.
 
why cant hackers hack itunes when they can hack almost ever thing in this whole world.hack itunes let people downgrade to older firmware,and save the new exploit from apple thts smiple

Yes, the SHSH file is unique to each device. That's why none of the replies to the three hundred "HELP I ACCIDENTALLY UPGRADED TO 3.1.3!!1!1" threads have been "Don't worry, here's my SHSH!"

I have no idea what the technical implications of hacking iTunes would be, so I can't speak to why they can or can't. However, what is obvious is that the Dev Team has chosen not to do so, for whatever reason. Perhaps there is a higher technical barrier to it. Perhaps they've just decided that their (volunteer!) time is better spent building on their previous work with the iPhone in order to keep jailbreaking possible on new hardware and software rather than trying to solve a problem that is, in most cases, really quite easily avoided.
 
if i downgrade to 3.1.2 would i be able to use my carrier inspite of the fact my baseband is not downgraded.people have downgraded to 3.1.2 from 3.1.3 but with newer base band and where can we find the boot number of our iphone like iboot3.. something like that?

No, even if you downgrade your baseband will not change and therefore no unlock.

INSTEAD of a Jailbreak/Unlock for 3.1.3, why not a hack that somehow allows a downgrade (bypassing the "signing" process) of firmware to an already Jailbroken/Unlocked release?

(for those without <3.1.3 ecid saved)

The implication of your statement is that this would somehow be easier than creating a new jailbreak for 3.1.3; nothing could be further from the truth. To accomplish what you are talking about one would have to gain low level control of the bootloader such as exists for the iPhone 2G. You're talking about permanently pwning the 3GS, something that has not even been accomplished for the 3G after almost three years! To use an analogy, it's like suggesting that rather than go through the trouble of trying to make cars more fuel efficient, it would be much easier just to develop instant teleportation.

It is not iTunes that prevents downgrades, it is your phone itself. Unpwned iPhone 3GS's will only accept a firmware file after receiving a signature response which varies based on your phone's ECID (this is the SHSH). iPhones with the old bootrom could be hacked to remove this signature check, but nobody has yet figured out how to hack the new bootrom in that way. It is possible to spoof the Apple servers if you have saved your SHSH from Apple either locally or to Saurik's server. If you have not, obviously, you can't do that.

Might it be possible to create software to generate SHSHs from the ECID alone? Perhaps. But nobody has yet done so, and there is no guarantee that they are even algorithmic; they may be randomly assigned to phones at manufacture as is the information needed for a factory unlock. To my knowledge, nobody is working on it.

But none of this will allow downgrades to the baseband. To do this would require a bootloader exploit such as has not existed since the earliest 3Gs' 5.08 bootloader.
 
so are you saying that signed firmware loads your shsh's onto the iphone, and ur iphone verifies it. if thats what you're saying, cant we modify itunes so that after its done restoring, it has like a spoof thing going on where it automatically loads on your shsh's? is there an app, or some way that we can find our shsh's. sorry if its kinda confusing but what im trying to say is that the firmware passes through a filter.

Please read what I've written. What I said is that phone itself requires a signature. The SHSH is that signature. It requests a signature from iTunes and unless iTunes returns a valid SHSH for the version of firmware and for your phone's unique ECID, your phone will refuse to restore. There is no way to fake an SHSH. There is no software to generate SHSHs, only to save SHSHs retrieved from Apple. If you have your SHSH saved, it is possible to spoof the signature server...but only if you have your SHSH saved.

Once Apple stops signing a firmware version, it is impossible to get the SHSH. And without the SHSH your phone will absolutely refuse to install that firmware. The only way to prevent the iPhone from demanding this signature is to modify the phone itself (not iTunes). Specifically, the phone must be 'pwned' (that is, iBoot must be altered to remove signature checks). Such an iBoot hack is precisely what those of you with tethered jailbreaks don't yet have. Until the 359.3.2 bootrom is pwned, there is no way for you to install even a custom 3.1.2 firmware to your phone without a cached signature from Apple.

Or and this is just a wild stab in the dark and I could be accused of being "way out there" in my thinking, but how about you listen to what everyone is telling you and either return your phone or wait with much wringing of hands until 4.0 is out and the dev team bring out a jailbreak??????

Cmon be a sport and shut up for a while!
 
How about if you have 3gs with 3.1.2 7d11 mc model currtent jailbroken via blackra1n
i was too late in getting cydia/tss.
but i really need to restore my phone thus i wonder if PwnageTool 3.1.5 can restore my phone to 3.1.3 with jailbreak (and preserving baseband).?
Thanks

If you have an untethered jailbreak, you can restore to a custom 3.1.2 or 3.1.3 firmware. If your current jailbreak is tethered I'm afraid you can't. A phone has to be pwned to install a custom firmware.

hopefully your iphone has a hairline crack and is still under warranty. If so take a friends official carrier sim and take it to apple. See if you get a replacement. chances are that you'll end up with a new/refurb 3.1.2. Be careful and then jailbreak and unlock it. By being careful I meant, don't mess up the jailbreak or you'll have to get back to 3.1.3.
 
yep

because if the dev team doesnt release it to the public, apple wont know what exploit they found, and how and where to patch it up. thats why...so it will remain until after they release it, and a new software update happens. also an exchange excuse could be for more memory or a different color. there im helping you now.

this is why the Dev team is always careless about when and how they release JB and unlocks to the public. They even taunting Apple as well because Apple isn't smart enough to figure out how the Dev team or Geohot found the exploit. :rolleyes:
 
Thanks for the replys.
since i can't restore/ go to 3.1.3 without loosing jailbreak.
i will have to work out my problems = some how my phone dialer,google map,ipod and calendar were "deleted" gone from the phone somehow???
when i try to call using other contact app( MyPhone+) the iphone gives me "unsupported url...url wasn;t loaded"...
how and where can i get these original built-in apps reinstalled,
can i just copy them from another iphone and put them in the application directory via openssh?
thanks
 
yes, or you mite have hid them by accident. if u have sbsettings, open that up, select more, then hide icons, and switch the missing icons to off...they should reappear if you happened to hide them by mistake. also with categories check your folders.
 
pcs are junk,
thanks for your suggestion but i have done all that...some how they (ipod, dialer, appstore,mail,google apps) are GONE ! no where to be found (even in the settings , i don;t see mail option anymore?!
 
Hrmph. The wife upgraded her 3GS to 3.1.3. And even though I used Cydia to store the SHSH stuff last week while the phone was jailbroken with 3.1.2, pointing iTunes at Saurik's server doesn't work. I even ran tcpdump and watched it connect to the right server, and still, no worky :(. I guess that's the downside of having to rely on someone else to store this kind of information.

If Apple is successful at eliminating jailbreak altogether, I'm done buying iPhones. There is respectable competition now that wasn't there a couple of years ago.

Were you in DFU mode? You can only downgrade in DFU mode.
