Had to take a break and now I'm back to researching this again. If I remember correctly, I asked MuscleNerd this question about a year ago for the fw3.x.x discussions. I *think* he said Pwnage doesn't require the signing, but can't remember if that also referred to fw that wasn't being signed by Apple anymore. I have to see if Twitter will let me scroll that many months back. We had a brief twitter convo about it. I retweeted the question to him, crossing my fingers he'll be interested in answering again among all the questions he gets.

You need to install Firefox first since it doesn't come pre-loaded on Macs. When you download Pwnage, Firefox will ask what you want to do. Choose Save to your desktop. Don't let Firefox open the file. I like the Mac-iPhone tutorials at hackthatphone. iClarified is good too. We're not allowed to put links here so you have to google them.

I'll probably just give a go later tonight or tomorrow if I don't find any concrete infos. I have my SHSH files and my old custom 3.1.2 ipsw if anything goes wrong.

I'm searching around to find my old notes on this...and to see whether I can find the old posts on it from last year.

Mon, 19 Jul 2010 02:11:04 +0000 http://blog.iphone-dev.org/post/827014787#IDComment87413150 http://blog.iphone-dev.org/post/827014787#IDComment87412863 Whoops...now I think I'm a bit confused. :p If my 3GS is on the Pwnage Train and Apple is not signing 4.0 anymore, I thought I could still use Pwnage 4.01 to make a custom 4.0 ipsw and option+restore to it in order to upgrade to 4.0. Am I wrong? My 3GS = 3.1.2, 04.26.08, old bootrom, always used Pwnage for JB I thought SHSH files were important for downgrading a 3GS to an old fw that wasn't being signed for which I didn't have a custom ipsw. As long as I have (or can make) a custom ipsw, I should be able to option+restore to it. Am I not remembering something correctly? Thanks for your help!

I suspected that. :) So why would the newer version and the backup be different sizes? Is one size correct and the other invalid?

I also don't think Apple signing is needed to create the custom ipsw. Wanted to check if I remembered correctly. About restoring to a custom ipsw, I was under the impression that if we have a custom ipsw and already are JBed, we don't need SHSH blobs to restore to the custom ipsw...*unless* it's a 3GS that is trying to downgrade. (Though, part of me remembers that the SHSH isn't needed if I'm downgrading to my own custom ipsw for an older fw...but, I never needed to downgrade so I'm not sure anymore what the steps are.) Here's why I ask. My 3GS is still on 3.1.2, jbed using Pwnage w/ modem 04.26.08. I want to upgrade to 4.0, and I'm thinking Pwnage 4.01 should still work for me creating and restoring to a custom 4.0 ipsw because I don't need Apple to sign an official 4.0 in the process. Right?

Cydia is just overloaded with SHSH requests the past couple of days. Use Tiny Umbrella. Check the "Advanced" box. Then select getting your SHSH files from Apple instead of Cydia. When Tiny Umbrella is done caching your files, save them to your computer.

Thanks for any anwers!

I remember you doing a similar Q&A a year ago that helped keep repeat questions to a minimum. Let's keep bumping this up. One thing I would like to know... 1. How many files should be cached if Tiny Umbrella worked properly while saving 3GS 4.0.1 SHSH files? 2. How big should those files be? I don't know if enough people have tried this yet. Tiny Umbrella cached 2 files for me, but I saw another person say they got 4 files cached by Tiny Umbrella. It would be helpful to see what the majority result is so we know if we've got them correctly.

I used Tiny Umbrella to save my fw4.0.1 SHSH files. Tiny Umbrella said is cached 2 files. Is this correct? Or, should it have cached 4 files? My iPhone: 3GS, old bootrom, fw3.1.2, modem 04.26.08 Thanks!

Click "Advanced" in Tiny Umbrella and choose the 4.0.1 iOS.

This much I know: 1. Open Terminal 2. Type /usr/bin/openssl sha1 But, then what do I type next? Thanks for any help!

Hope the drinks and whatever girl/guy was distracting at the bar were worth the shitstorm.

Sat, 20 Mar 2010 09:00:04 +0000 http://blog.iphone-dev.org/post/376648600#IDComment63143637 http://blog.iphone-dev.org/post/376648600#IDComment63120726 The 1600 error message usually means you are usng DFU mode when all you need to use is normal/recovery mode. What happened? You posted a few hours ago that everything was working after you upgraded your 3.1.2 using Pwnage. All you have to do is click Option+Restore (Shift+Restore on a PC) and then browse to the custom 3.1.2 ipsw you made with Pwnage. That will install your custom 3.1.2 back onto your phone. If you could upgrade to your custom 3.1.2 without problems, you should be able to restore to it also.

For tethering, look through hackthatphone's website (google the address) for steps on tethering. If you use ATT or another official carrier, it's fairly straight forward.
