How To: Save Your iPhone SHSH Files to Secure For A Jailbreak old and new way

Apple is very likely to push an iPhone firmware update anytime now. So, it’s time to save ECID SHSH on file to secure your jailbreak. It is important to do because when Apple pushes a new firmware, they stop signing the older firmware and without a valid signature, you cannot restore to an older firmware.
Once someone updates their iPhone 3GS, iPod Touch 3G, and iTouch 2G MC to the latest firmware without saving their SHSH on file, they not only lose their jailbreak but also the ability to downgrade to an older firmware. Bt if you have ECID SHSH saved for an older firmware, you’ll always be able to restore back to that firmware and then jailbreak your iPhone.
Note: This guide is important for iPhone 3GS, iPod Touch 3G, and iPod Touch 2G (MC) owners. iPhone 3G and 2G users are free of this headache.

How to Save iPhone SHSH Files

If you have a jailbroken iDevice, there’s a simple way to save SHSH files. But for those with a brand new device, you need to follow other steps. We are going to provide instructions for both:

If You’re Already Jailbroken:

Now that you have a jailbroken iPhone; Launch the Cydia app. Check if there’s any mention of “this device has SHSHs on file for iPhone OS: 3.0, 3.1, 3.1.2, 3.1.3 at the top of the Cydia home screen. If there is, then you are already set and don’t have anything to do. You may not have all SHSH on file but it’s OK to have the latest one. Current latest firmware version is 3.1.3, so make sure you have that one mentioned there. Checkout the following screenshot:

If you already saved your SHSH file on Saurik’s server, you don’t need to repeat this process every time. If there’s nothing mentioned at the top of the Cydia home screen, scroll down the Cydia home page and look for “make my life easier” and top on it. This will automatically save your ECID SHSH on Saurik’s server. To confirm, simply close and re-open the Cydia app and see if there’s a mention at the top now!

That’s it, you don’t need to do this for each new firmware, Cydia will automatically save ECID SHSH of future firmware for you.
Advice: Never update to the latest firmware unless one of the iDevice hacking teams releases a jailbreak tool for the latest firmware.

For Both Jailbroken and Not Jailbroken Devices

If you have a new iPhone or are afraid of jailbreaking it at the moment and just want to see if the jailbreak tool really works for others, it is highly recommended to save your ECID SHSH on file as soon as possible. The current firmware version is 3.1.3 but Apple is expected to release a firmware update anytime now, so grav your ECID SHSH file before it’s too late. You can save SHSH Signature files even if you aren’t jailbroken. Follow the steps below to grab ECID SHSH on file for a jailbreak free device:
Note: You can save ECID SHSH on file only for that firmware version that Apple still signs, currently it’s 3.1.3. It’s very important to keep doing this for every firmware version that comes out after these. But if you jailbreak your iPhone at any point in the future, simple follow the jailbroken device steps mentioned above and leave the rest to Saurik.

1. Get your iPhone ECID using the following guide: How TO: Check Your iPhone ECID.
2. Download the firmware Umbrella from here and Java Runtime from here (it’s required for Umbrella to run on Windows.)
3. Run the downloaded firmware Umbrella (both windows and Mac version available in download)
4. Enter your ECID
5. Select your device version i.e iPhone 3GS 3.1.3 (or whichever you have)
6. Select SHSH Repository:
   1. If your iPhone is NOT jailbroken. Choose the Apple option from the drop down menu.
   2. For already jailbroken iPhone. Choose the Saurik Cydia option from the drop down menu.
7. It the submit button.

While downloading the SHSH’s the program will freeze for a minute or two and would seem like it isn’t responding, but don’t panic, it’s normal and soon enough the “SHSH Saved!” message will appear at the status bar of the Umbrella Window. Your iPhone SHSH will be downloaded and saved in the same folder that Umbrella is in. The file size will be around 64kb. That’s it!
