Jailbreak your iPhone

Grab and get Signed your ECID for iPhone 3GS OS 3.1

Advertisements

Good news for those who accidentally upgraded their iPhone 3GS to OS 3.1 and they didn’t captured their ECID signature dump files earlier, Props to iH8sn0w for find a way to provide the ECID signed to all users who have not had time to save them at the time of 3.0. These files will help you to downgrade your iPhone firmware 3GS from 3.1 to 3.0 and then to perform even the Jailbreak!

Warning (Please Read) : What is written below is solely and exclusively for the iPhone owners who have installed by mistake 3GS firmware 3.1 and who are interested to get their certificate in order to run the Jailbreak (when it is ready to DevTeam). Don’t try this on your OS 3.0 because apple pulled their servers to signing OS 3.0 and 3.0.1 so be careful. In short, this guide lets you get the ECID signed to all those people who have not had time to save or who buys an iPhone firmware already 3GS mounted 3.1

ECID : This is a unique chip ID and will be different for every iPhone. When iTunes starts the restore process, they contact Apple servers to generate signatures just for your device. It’s important you get these signatures for your phone before a new version of the software comes out.

Why i need ECID Dump : Apple added a new piece of security called ECID, The nature of the 3GS hardware allows Apple to stop IPSWs from being usable unless you’ve already gotten the signed chunks they send to you based on your ECID (a unique chip ID). Actually Apple applies ECID so the iPhone will refuse to accept the ipsw file while downgrading because of a bad signature. It will treat it as a custom ipsw without having the apple server sign the ipsw specifically for your phone id before flashing.

    I got a “Delivery to the following recipients failed.” when I try to send the file via e-mail to ih8sn0wydaz@gmail.com. What should I do now?

    Same as Clark

    Dear Sir,

    I got a “Delivery to the following recipients failed.” when I try to send the file via e-mail to ih8sn0wydaz@gmail.com. What should I do now?
    And did the new programs release yet? Or can I now count myself as one of the lucky peoples who did saved their SHSHs on Cydia and use Saurik’s way to downgrade to 3.0?

    Hi oterol2000

    Same Problem for me, any news for that ?
    I’ve tried the same method on the same computer with a friend’s Iphone JB 3.0 like me, and it has worked well… so weird

    Hi,

    I am entering the number in the black box, but I don’t understand what you mean by ‘click enter.’ I’ve used the “enter” button on my keyboard (MAC SNOW) and I’ve looked for an ‘enter’ button on the page. When I hit enter, the status bar shows that something is sent, and something is waiting for a reply, but nothing appears to “download/save a file.”

    What am I probably doing wrong, that’s right in front of my face?

  11. scream91 September 19, 2009 Reply

    Hey, a question have been posted there since few days and nobody answered it, so i guess nobody knows, but do somebody know any other way to get all this files when we only got ECID? as Purplera1n no longer answer us?

    Need for help! Same problem as @Raindrop, after pushing ENTER key, it start to make some work and then nothing happens.
    Please, can sombody explain better?
    What kind of extention the downloaded ECID file should have?
    Thanks!!!

    @Raindrop
    I used the USBview and grabbed my iPhone 3GS 3.0FW ECID, worked great!

  14. Raindrop September 18, 2009 Reply

    Hi, I pasted my ECID code onto the purplera1n website and pressed enter,,,but I did not get a file. Just a purpera1n program. When I open it, it says Make it Rain. Please advise. I use a MAC with the Iphone 3gs with the OS 3.1. Thank you,

    Is this necessary/possible to perform on 3G iPhone? Since I have upgraded to 3.1 from 3.0.1(jailbroken) and I am not sure if I will be able to jailbreak it again.

  16. Paige September 14, 2009 Reply

    This *will* NOT work! If ih8sn0w is simply changing the ECID in the files, then the built-in checksums will fail! Here is the results of my analysis… I had a friend send his iBEC (tmpl), mine is (mine) and the hacked iBEC is (hack). All I did was change the ECID, nothing else. Here is the results of md5:

    MD5 (iBEC.n88ap.RELEASE.dfu-hack) = 6e251e77cf6de9ff354fdf7dc092ae7a
    MD5 (iBEC.n88ap.RELEASE.dfu-mine) = ffd88bfa0456e970ecd9385c0bc21f87
    MD5 (iBEC.n88ap.RELEASE.dfu-tmpl) = bad89114939860c8b8aa2d9c33f35e0b

    So BEWARE!

    Hi,
    I run the second method to extract the ibec and ibss. In step 1, i run the recovery to get the ibec, but i found that the ibss is also created in the same folder. It’s that correct?

    • Vinay September 14, 2009 Reply

      @ gene yes it’s correct

  18. Rendszergazda September 14, 2009 Reply

    And what is the method of getting these files on a 3.0.1 version software?

    • Vinay September 14, 2009 Reply

      @ Rendszergazda No 3.0.1 is officially discontinued from Apple servers. this is for those who already upgraded their phone to 3.1 and now stucked on upgraded baseband..

  19. nightwalker September 14, 2009 Reply

    ist it also the way for Iphone 3G users or only for Iphone 3GS
    i unfortunaltely updated my jailbreaked iphone 3G with the new itunes 9 and now i have the latest BaseBand and FW 3.1.
    i could manage downgrade on FW 3.0 with redsnow again but BB still on 05.11.07

  20. Vinay September 13, 2009 Reply

    @ ZMA @ John Explore those folders and find for the following files “iBEC.m88ap.RELEASE.dfu” and “iBSS.n88ap.RELEASE.dfu” they need only these two files including your ECID string

  21. ZMA September 13, 2009 Reply

    Hi,

    FYI. Could not find the ECID number after restoring version 3.1 using restore IPSW. However, when I do not alt shift in clicking restore, I have the ECID number. However, when I use the ECID number received the error “Something went wrong” from the purple rain website.

    Hence, have use the other method to generate the file as described by you.

    Have 3 directory created PerfBD.tmp, PerfBF.tmp & PerfBE.tmp. If I zip the file, total is 32 MB. May be distressing for your mailbox.

    Please advise the specific filename to email you.

    Hope you can help.

    ZMA.
