Hello, I have an iPhone 4 jailbraked with 6.1.2.
I have saved the SHSH blobs with tinyumbrella for the following firmwares:
iPhone4 6.1 (10B144) iPhone4 6.1.2 (10B146)
iPhone4 6.1.3 (10B329)
I have read something on Saurik's blog that some of the saved SHSH won't be useful for downgrading - even if they have been saved during the signing window. How can I be sure that those blobs are useful?
I fear that cydia may have saved them in the -bad- period and then tinyumbrella might have requested them from cydia.

I'd like to test iOS 7 but I'd like to be able to revert to 6.1.2 if something goes wrong... Any hint?

Use iFaith to check your blobs and see if they are valid. Either way, you can and should get new 6.1.3 blobs using iFaith.

Ok I am in windows 7, I have downloaded iFaith, run as Administrator, selected "DUMP SHSH blobs" followed the instruction to enter DFU mode. iFaith says: You failed to enter DFU mode. Try again. but the phone IS in DFU mode, it does also say so in the USB device details: "Apple mobile device (DFU mode)"

any hint on what am I doing wrong?

(18 Sep '13, 16:14) nick2k3 nick2k3's gravatar image

I have never done it on win 7, as the matter of fact i probably never will...

(18 Sep '13, 16:21) slavakulikoff slavakulikoff's gravatar image

so what os should I try it with? windows 8? I have seen videos on youtube in which after a few seconds ifaith says to release power button it quickly recognize the iphone.. instead I get the second countdown to expire and then I get the failed dfu mode.. any help?

(18 Sep '13, 16:39) nick2k3 nick2k3's gravatar image

SOLVED: I updated itunes and thus I think some drivers and then ifaith quickly recognized the phone in dfu mode. thanks!

You should also do "Show available SHSH caches on server" to get 6.1.3 before it's too late. You can try uploading your 6.1 and 6.1.2 blobs that you have stored locally with this option as well, and iFaith will check to see if they are valid (they likely aren't, but it's worth trying).

I already have 6.1.3 shsh both on cydia and tinyumbrella :)

one question, I have recovered the 6.1.2 certificate with iFaith and I will eventually use it for downgrading; I used to have (locally) a 6.1.2 certificate which I don't know if it has been grabbed from cydia. However I tried the "verify SHSH blob" function of redsn0w and it says the old 6.1.2 certificate is OK. Should I trust it? can I use the certificate obtained with iFaith with redsn0w?

(19 Sep '13, 03:35) nick2k3 nick2k3's gravatar image

Redsn0w is really out of date right now, use iFaith instead. If you saved 6.1.2 blobs off of your device with iFaith, you can use iFaith to stitch those blobs into an IPSW, enter pwned DFU mode, and restore to 6.1.2.

(21 Sep '13, 06:18) compilingEntropy compilingEntropy's gravatar image

If Cydia lists those SHSH blobs at the top of the "TSS Center" (linked from the Cydia homepage), they are valid blobs saved on Cydia's servers. Cydia doesn't display invalid blobs. (It's also possible though that you have valid blobs saved only locally and not on the servers.)

Cydia TSS Center says I have 5.1.1 and 6.1.3.
Tinyumbrella says I have 6.1.2. I guess I'll try and see if the last one is OK signign an ipsw ;)

(18 Sep '13, 15:29) nick2k3 nick2k3's gravatar image

The reliable way to verify shsh is tool called ifaith. If you saved those shsh with tinyumbrella then they are corrupted and cannot be used, however you need to verify it. If your iphone4 is on 6.1.2, you can dump shsh srom device with the same ifaith.

That's incorrect, TinyUmbrella blobs are perfectly valid. It's only when you use TinyUmbrella to save blobs from Cydia's servers, which saved invalid blobs, that TinyUmbrella gets blobs that aren't valid.

(18 Sep '13, 13:22) compilingEntropy compilingEntropy's gravatar image

That is what i meant. Based on my general observation, that is how most users save shsh with "request shsh from cydia" checked. You are right about cydia corrupting 6.1.2 blobs, not tiny. However if OP does not have valid shsh for 6.1.2 ifaith must be used to dump them from the device, and/or the only way to verify them is to use ifaith.

(18 Sep '13, 13:30) slavakulikoff slavakulikoff's gravatar image

It does not work that way. Blobs are unique to the device. You cannot use any blob on any device other than the one Apple issued to, or for that matter for any other iOS version on that phone or any other. Any blob other than one issued to your device is USELESS.

According to iH8sn0w, as of the moment, no. Apple broke iFaith stitch downgrades from iOS7. Wait for an iFaith update.

Sorry, SHSH Blobs are unique to a particular device; sharing them helps no one.
