      I download the firmware ipsw (4.2.8) but there is no ipsw file anywhere in the folder. I am obviously doing something wrong, but what?

        If you are using Internet Explorer, it changes the extension to .zip for some reason so rename the file and change it back to .ipsw or use a different browser like Chrome or Firefox.

      how do i get 4.2.8.shsh into tiny umbrella

      • http://iphoneblogr.com JaeM1llz

        Go to the advanced tab and check the box that says “request SHSH from Cydia” and then hit “Save SHSH”

    • chris

      the shsh wont show up on my tiny umbrella. i did what you told jon to do but its not there

      • http://iphoneblogr.com JaeM1llz

        If it’s not there that means you didn’t save it while it was being signed so you won’t be able to downgrade.

        • chris

          well now its stuck in pwned dfu how do i get it out. and how do i get the snowbreez 4.2.8 in tinyumbrella

          • http://iphoneblogr.com JaeM1llz

            Hold down home+power for 10 seconds to reboot and like I said, if you didn’t save your SHSH in TinyUmbrella while 4.2.8 was being signed, it’s too late now.

      Where or how can I check if I have those SHSH files??? I have an iPhone 4. 4.2.10 and my phone has never been jailbroken and I wanna be able to jailbreak it but that’s not tethered. How can I do this? Thanks!

      • http://iphoneblogr.com JaeM1llz

        If your phone has never been jailbroken before then you dont have your SHSH. You’ll have to deal with the tethered jailbreak for now until iOS5 is released and jailbroken.

      I have no idea if I have my SHSH files or not. I had my VZW iPhone jailbroken previously with GreenPoison. Had signed into & installed apps with Cydia. Phone got updated to 4.2.10, and am trying to downgrade. Is there a way to get those previous SHSH files from Cydia now? I gather having a Cydia account & used it, that they should have them? Am a bit confused by that step. Thanks.

      • RobM

        When I load Cydia on a tethered jailbreak, I do see SHSH: iOS 4.2.8, 4.2.10. That means I’m good? it’s not a file on my laptop anywhere, right?

        • http://iphoneblogr.com JaeM1llz

          Correct. Just follow this tutorial but first open TinyUmbrella and go to the advanced tab and check the box that says “Request SHSH from Cydia” then hit “Save SHSH” this will transfer your 4.2.8 SHSH to your computer and allow you to follow this downgrade tutorial.

          • RobM

            Big props! It worked beautifully. I was trying to tell in TinyUmbrella if I had SHSH, and just was looking in the wrong place. Thanks again. Finally back to an untethered JB!
