How To Backup SHSH Blobs (ECID SHSH) Using Firmware Umbrella [Mac]
SHSH blobs or ECID SHSH is a unique digital signature that Apple assigns to each iPhone, iPod Touch and iPad. Whenever you connect your iPhone 3GS or iPod Touch 2G/3G or iPad to iTunes to restore or update iPhone OS firmware, the ECID is sent to Apple servers for authentication...

just letting u know that they do restrict ecid for the iPhone 3G because I tried downgrading from 3.1.3 to 3.1.2 and the old traditional way (aka downloading whatevr firmware u want, then alt + restore in itunes) doesn't work. I had to modify my hosts file with a few commands and then retry with iTunes. Worked fine. However, I can't get umbrella to work with my iPhone 3G. It recognizes it, has the ecid and my type of phone, but I just can't find the saved file on my mac anywhere.

I have the same problem...everything goes fine and I see the notification that my shsh has been saved, but I cannot find it anywhere on my Mac. Can anyone help?

you can fid your shsh where Umbrella software is if you cant then its not saved

this worked with the exception of the password not working but worked fine once i reset the password with the install disk.
Thanks

I found the instructions to be to complicated for the average user. In fact, some of the items written in your instructions did not appear when I tried to enter information in the Terminal app. You need to make the instructions simpler for computer dummies such as myself.

A) Click the 'Advanced Options' checkbox to see the additional fields (like ECID).
B) Once the file is saved, the log window at the bottom will have a link. Click the link to open the Finder window where your file was saved. -
Do we need to do this if we have the SHSH saved by Cydia?

i have a iPhone 3Gs new bootrom, jailbroke it with Spirit, had it unlocked for Tmoblie for a week then decided to updata with 4.0.. didn't know about saving SHSH, so i cant jailbreak it anymore or do i have to sell it cause i have Tmobile. ....HELP.

Hey rayp35, I am in the same situation. Did you find any information about that? I bought my phone off eBay and its a 3Gs, new bootrom and the seller updated it to iOS 4.0, so now I can't jailbreak. Let me know if you find anything.

Same situation as Viren.
The solution is to save the SHSH of th IOS 4.0 and wait for the new JB tool from the Dev Team.
Props,
