iPad Need help! Unable to restore to iOS 5.1.1 for iPad 2 with SHSH Blob and redsn0w

[timidhermit]

I need some serious help.

I have an iPad 2 running iOS 5.1.1.

I am trying to use redsn0w 0.9.15b3 to do a restore to iOS 5.1.1 (same iOS version). I have the SHSH blob for 5.1.1 locally, which I can load up.

The problem is that at the end of the restore, I am repeatedly getting an error from redsn0w reporting that it "couldn't obtain fresh baseband blobs". I don't recall seeing this before, and I have done such restore successfully in the past using the same method.

Can someone please help?

Ipad 2 wifi or 3G?

Make sure you download the right IPSW file

Yes, I have the correct IPSW.

Did you verify the blobs and the aptticket?

Did you do an OTA to 5.1.1 or via itunes?

How do you verify the blobs and aptticket? Is there an option in redsn0w.

No, I never do any OTA update. Always complete restore.

This is just a guess but maybe the Apple server address that Redsn0w uses to access the latest baseband firmware has changed. Maybe Redsn0w needs an update???

That is actually one explanation I thought of too.

If this is indeed true, I would have expect a lot more news in the JB community complaining about this. Any other ideas?

you can use redsn0w or ifaith to verify the blobs. I think ifaith is the better tool to check but I don't think it matters for iOS 5 blobs

I checked and the SHSH blobs/APTicket were verified.

However, the problem appears with the baseband signing, not the IPSW signing. Does anyone know if if this has become an issue since iOS 7 went live? I ask because I had done this same before without any problem when iOS 6 was still the current iOS.
