Once Apple stops signing that firmware version, there is no way to get the SHSH that will allow the restore to continue. Just like you can't go back in time and invent Google. It's done. It is in the past.

thanks for the humor.. a simple yes or no would have worked... im thinking its a file so i thought it can b extracted somehow

No, it's not on your iDevice.

That's not really answering the question... Just because 4.2.1 blobs aren't being signed anymore, you can still get 4.3 blobs. The question is whether a device in DFU/Recovery mode is still able to provide sufficient information to TinyUmbrella for it to do an SHSH request to Cydia/Apple servers.

spockers tru and thanks for the reply!! endareth is it possible?

(14 Mar '11, 22:11) greeng4ng greeng4ng's gravatar image

Never know till you try :D Debating putting my iPhone into Recovery Mode to test it out...

(14 Mar '11, 22:14) Endareth Endareth's gravatar image

TU wouldn't put my iPhone 4 into Recovery, and I'm feeling too out of it to do it manually. Anyone else got a DFU/Recovery device they want to confirm this with?

(14 Mar '11, 23:24) Endareth Endareth's gravatar image

Confirmed. Tried it in DFU and recovery, results: Nada, nyet, nothing.

@spockers am not sure if you're getting updates on this case as it seems the CC and answer forwards of the site are changing, but just as @Endareth just pointed out TinyUmbrella can retreive SHSH blobs (the current one and the ones saved on Cydia) even if the device is in recovery/DFU mode provided you have its ECID or have its profile added previously to TinyUmbrella.

@Endareth, Of course it's answering the question, the OP is trying to extract 4.2.1 shsh's from firmware on the idevice, noone is talking about 4.3 but you, and why would you need those to restore if it's still being signed. I think notcom knows what he's talking about, I find it hard to believe you think otherwise.

If they could have been extracted in this way, while the window is closed, it would of already been done.......OP, it wasn't humour I was trying, I was just quoting in full what notcom said, explains it very simply in my view. Go read the FAQ

I guess I was reading the questions differently. "can i extract shsh blobs in dfu mode or any other way with an unsuccessful jb?" more as a hypothetical (and definitely interesting) question. I never saw it as someone asking if they could still get an old 4.2.1 SHSH. It would help if people were just a wee bit clearer in asking their questions :-)

(15 Mar '11, 19:26) Endareth Endareth's gravatar image

Wow, lots of drama, no need to watch soap operas. I'll summarize for those not wanting to read all the arguing.

If the question is "can I extract SHSH from my device" the answer is obviously no, they are not stored there in any form.

If the question is "can I get TinyUmbrella to pull SHSH for my device if it's in recovery mode" the answer is "find the device ECID, plug it into TU and push the button, but it will only retrieve what's already at Cydia or what is still being signed by Apple."

Sincerely, Captain Obvious

No need for sarcasm, if it's a soap opera to you then don't bother posting or getting involved The issue here is cleared up by the first comment made by the OP, so we need to just make sure the OP or anyone else reading it gets the correct information. Now lets let it lie, but I will start to clean up these advertising links, if people are gonna signup just to spam their own site then it's gonna stop.

No you can't, I think you may have misread the question, ECID# or not, you're still not getting shsh's for any firmware version where the signing window of that said firmware version is closed. When you or the people voting this answer up as being correct, can do so or can extract those shsh's via the firmware currently on an idevice (window closed) that is in DFU/Recovery mode, then please post back. I don't think we are talking about being stuck in a recovery loop here,that's not what I think the OP was asking, why would you need to worry if TU recognises your idevice in DFU mode to then save shsh's, why not just get out of DFU mode and then do it.

(27 Apr '11, 02:05) venusanann venusanann's gravatar image

@venusanann while you might have the best "reading" of the OP's question, why does it bother you so much when others have a different reading of the question. The OP himself asked @Endareth for more details after @Endareth commented on the possibility for 4.3 blobs but not 4.2.1

(27 Apr '11, 06:06) knightz4u knightz4u's gravatar image

But the OP commented that he/she thought that the shsh's could be extracted from the firmware, which they obviously can't. That's how I read it and the OP confirmed it. You can read it how you want, but you still cant extract shsh's from the firmware, in any mode. Why would you want to try TU by putting your idevice into DFU mode when it works perfectly well without doing that, I'm sorry but I don't understand the logic of that.

(27 Apr '11, 06:53) venusanann venusanann's gravatar image

Yeah, it doesn't matter if your device is fresh and new out of the box, or a burning pile of plastic, the SHSH never comes from the device.

It isn't extracted from it, it isn't recovered from it, etc. It always comes from Apple. If Apple isn't signing that SHSH, you aren't going to get it.

I get SHSH blobs from Apple on a regular basis for several devices I don't even have connected to my system (such as my Apple TV and a friend's iPod Touch). It doesn't matter if those devices are working, broke, in DFU mode, or simply destroyed from existence. You just provide an ECID#, and Apple returns the current SHSH.

(27 Apr '11, 09:00) Xenomorph Xenomorph's gravatar image

I agree that once Apple stops signing a firmware authorization then there is no way to get them if they were not stored. However do you agree its good information for people to know that you can create a custom device in TU without the device and get the SHSH blobs, in case the OP's device has saved SHSH on Cydia would make this the most proper answer. My point is we should encourage people to share good information that in my opinion is relative especially for others who scan this forum looking for answers.

(27 Apr '11, 09:01) knightz4u knightz4u's gravatar image

If people want to know what the manual ECID button in TU does/means then let them ask it and the answer shall be given. If you just want to spam/advertise your own site links then make sure you at least get it right. This is the JBQA, not an advertising forum.

(27 Apr '11, 09:52) venusanann venusanann's gravatar image

I never knew i could do this in this way. Thanks to Wolverine. Not many people know this trick.

(27 Apr '11, 10:24) BilalBhatti BilalBhatti's gravatar image

Lol, then you've never looked at the settings/buttons/options of TinyUmbrella, it isn't a trick either, it's a straight forward process for people that can work it out. I see you've tried voting this up twice, are you part of the jaxov fail team as well lol, surprised you didn't post about your amazement 9hrs ago when you first voted it up lol, don't you get any hits over there. There will be no more spamming of that site, it's full of piracy info/help, go spam it elsewhere, not here. The jaxov tutorial is a joke anyway, it's titled ".........when iphone is stuck in recovery mode loop" and the first instruction is a three step part on how to put the idevice into recovery mode rofl, why would you be doing that if you're already in a recovery loop, obviously just copied from a different source and then a new fail title added, just another reason to stay away from sites like that, go to iclarified for a reputable tutorial on getting your ECID#. Jaxov = fail
