  • Apple Stops Signing iPhone OS 3.1.2


    Okay folks. We said it a few days ago. And we're going to say it again. It's quite clear that iPhone OS 3.1.3 is nothing but trouble. We saw a release of a new redsn0w that allowed 3.1.3 but it is NOT recommended. Even from the Dev Team. It's for experimental purposes only!

    To top it all off, BigBoss is reporting that Apple has stopped signing the iPhone OS 3.1.2 firmware, meaning that you can no longer use iTunes to install a custom firmware of 3.1.2. This also means that if your on 3.1.3 you cannot downgrade, but if you've been following along, you should know that already. YOU CANNOT DOWNGRADE! If you've saved your SHSH's on Cydia or Rock, you may be in luck for downgrading, but its not guaranteed to even work.

    Now from what I understand, even if you have not upgraded to 3.1.3, if you haven't saved your SHSH's with Cydia or Rock, if fails or something goes wrong with your phone causing you to need to restore, you will NOT be able to install your Custom 3.1.2 firmware. I reapeat, AS OF RIGHT NOW, YOU WILL NOT BE ABLE TO INSTALL STOCK FIRMWARE FOR 3.1.2 THROUGH ITUNES! No matter if your on 3.1.3 or 3.1.2 or lower.

    This information seems to be highly aimed towards the new iPhone 3GS and iPod Touch 3G. From the sounds of things, the iPhone 3G and 2G are in the clear. How that works, I have no idea, the information is very vague at this point.

    If anyone can shed some light on how this works, and how iTunes can magically stop signing firmware (I was unware it even signed anything when installing custom firmware... if this is all the problem was, why didnt Apple do this a long time ago?), or maybe some motivated hacker will find a way to trick iTunes into signing a package that will let you install a custom firmware other than 3.1.3.

    All in all, this appears to be a big attack by Apple on the Jailbreakers out there. Is this just the beginning of their crackdown on Jailbreaking? I sure hope not. Jailbreaking has brought their products to new levels. In my opinion they need to secretly let jailbreakers do their thing, as it really only benefits their products and store.

    News of this comes from BigBoss, but I gotta say, there isn't much solid information there.

      Saurik's servers use gs.apple.com to grab your ECID files, and does this automatically for each firmware release, whether it's installed on your device or not. All you have to do is allow Cydia to do so, if you haven't done so you will see a prompt on the page that shows when Cydia first loads. You can't miss this, you have to be blind or retarded to miss it.

      You then follow the instructions on saurik's site ( Caching Apple's Signature Server - Jay Freeman (saurik) ), edit your hosts file to redirect gs.apple.com to 74.208.10.249 (a Cydia TSS server) and you're set. You can ALWAYS downgrade to the firmwares that you have SHSH blobs on file for in Cydia.

      If you've done this and you upgrade to 3.1.3, you can downgrade your OS to 3.0, 3.1, 3.1.2 as long as you have one of those SHSH's on file (if you allowed Cydia to do so at 3.0, then you will have all those and 3.1.3 as well for when and if it's jailbroken). If you don't have your 3.1.2 SHSH on file (or ignored that prompt until now), then you are now too late and cannot ever restore back to 3.1.2 no matter what you do as Apple's servers have stopped signing 3.1.2 and Cydia can no longer grab SHSH's for that firmware.

      I hope this clears things up. It pains me to see news posts that lack such vital information.
      ^^ What he said. If folks have been paying attention all along, you edited your settings in iTunes so you could avoid the "signing" issue.

      Apple has been signing the firmware since the 3gs came out....there was no way to downgrade below 3.1.2 before. This is the EXACT same thing that happened with the last 2 firmware releases for the iphone 3gs.

      No offense but to be a member of staff and ask "why they didn't do this before" is kind of ridiculous.

      Just wanted everyone to know that this is NOTHING new. You can still downgrade as long as you have your ECID and SHSH blobs saved either on file, or on cydia. You need to use umbrella or you can even set up your own restore verification server.


      Not that I should be made a mod or anything...

      But as long as you have your ECID and SHSH blobs on file with Cydia you are safe. This article basically makes it sound like impending doom, but really Apple has stopped signing every firmware for the 3gs since 3.0

      I hope this helps.

      This is old news. Nothing new!!!!!!

      Edit Poseidon: How many new members do you think we've had since this happened last time? THOUSANDS!!! How many people have purchased iPhones since 3.0 came out? THOUSANDS MORE! Stop thinking inside your tiny tiny little box and think about the community as a whole when making these statements.

      guys, guys, guys....

      Everyone take a deep breath and relax. We go through this pannic every time Apple pulls this crap. And you know what? ~ Every time Jailbreak comes out on top.

      Its just a matter of time. So just be careful with your phones for a while ~ meaning don't do any weird mod that could brick your phone until we get a 3.1.3 jailbreak.

      chill out guys

      Updated to 3.1.3 on my 2G. No problems. All of those that are fortunate enough to have the newer models, please read the caveats within this thread and in the original article, and then read them again...

      We need a comprehensive backup solution for Jail broken phones. I'm scared to install anything in fear that it might brick my phone and I'd be forced to upgrade.

      I think Apple did something. Yesterday my iphone 3GS froze so i did a reboot and it was stuck on the apple logo. The only way to fix it was do a restore. Now im at 3.1.3 awesome. Steve Jobs can blow me.

      Read page 1,2 and 3. Read about me and other people conversation. It can restore to 3.1.2
      I just make it. Read carefully about these conversation if u want to get back 3.1.2 jailbroken.
      And read this

      You should also mention that if you do not want an unlock you can upgrade to 3.1.3 but not recommended. But if you want jailbreak you should not upgrade to 3.1.3 because upgrading to this firmware updates your baseband which is what prevents you from having an unlock.

      I would honestly not update to this firmware version unless you have no choice. Luckily for me i saved my shsh files on Cydia. So if i have too and i really hope i wont, i can just restore with custom 3.1.1 or 3.1.2

      I'm still on itunes 8.2.1.6 as I don't like 9.* itunes.
      I just installed 3.1.2 about 5 mins ago and its fine. I even downgraded a 2G iphone yesterday from 3.1.3 to 3.1.2 via DFU mode and no problems.
      There is no need to install a lower version of iTunes.
      You seem to have missed the point of completely. The 2G and 3G iPhones do not have the problem it is only the 3GS and iPods with serial numbers starting MC that the new security measures have been implemented.

      RedSn0w works to JB 3.13 on the 2G and 3G - but not the 3GS. 3G iPhone owners should not upgrade if they want a software unlock as it updates the BB and there is no software unlock for BB 05.12.01

      If you have any doubt check the Dev Team Blog.

      umm...i would really like to know how to set up my own server so i can sign my own files. Just in case if Cydia goes down i'll have a backup.
