Save Your iPad 3.2 ECID SHSH Files to Secure Your Jailbreak
So you got your iPad and waiting for a Jailbreak or you got your iPad and may jailbreak in future, in both cases grab your iPad 3.2 ECID SHSH’s on file and set your jailbreak future safe. iPhone 3GS jailbreakers are more familiar with ECID, SHSH terms. For those who are new in the scene, ECID is a unique chip ID and will be different for every iDevice. 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 iPad before a new version of the software comes out.
Now question is Why i need ECID SHSH Dump ? Apple added a new piece of security called ECID, The nature of iPad / iPhone 3GS / iPod Touch 3G 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.
In easy words, iPad released with OS 3.2 and a jailbreak for iPad will be available very soon. Apple will push a new update 3.2.1 or something like that with a fix for previous jailbreak, same time Apple will stop signing 3.2 firmware from their server. Once Apple stop signing 3.2 neither you can downgrade from 3.2.1 to 3.2 nor you can restore your iPad 3.2 back to OS 3.2 unless you saved your SHSH Dump. We’ll publish detailed guides as soon as Apple release a new firmware so stay tuned with us. Anyway, you can grab your ECID SHSH on file even when you are not jailbroken, and here is how to do it. Of course this will only be possible for the firmware version Apple still signs, which is (right now) 3.2
