Are you growing tired of waiting for an iOS 5 jailbreak? Do you wish you could go back to the good old days of iOS 4.3.3, when jailbreaking was simple? If you answered yes to either one of those questions, you might be interested in TinyCFW.

TinyCFW is a new downgrading tool by TinyUmbrella-creator NotCom. Using your saved SHSH blobs, you can use TinyCFW to downgrade your iPhone 4 or iPad 2 to iOS 4.3.3 so you can go back to having an untethered jailbreak.

NotCom explains:

“TinyCFW is a simple tool I put together for a friend of mine. He has an iPad 2 GSM and has his 4.3.3 SHSH but since Apple is no longer signing 4.3.3, it isn’t possible to downgrade to 4.3.3 without getting stuck in a 1015 recovery loop.

– It will modify an existing IPSW for an iPad 2 GSM/CDMA or iPhone 4 GSM/CDMA

– It WILL modify the IPSW to update your baseband to the latest

– It will create an IPSW that you can use with TinyUmbrella AND iTunes to restore to a version of iOS that you have SHSHs for

– It is primarily for iPad 2 with a baseband OR iPhone 4.

NotCom also warns that he never intended TinyCFW for public release. It was just a tool he made for a friend that he figured he would share with others looking to do the same thing. He says we can expect its functionality in far more robust form in TinyPwn, a future release.

We hope to have a TinyCFW tutorial up soon. But for those who want to give it a shot beforehand, you can grab the utility from our Downloads page. If you get stuck, NotCom has some light instructions for using TinyCFW on his website.

    is there any way to downgrade an iPod without the shsh blobs?

    • No blobs downgrade …
      Why do people keep asking this…a simple google search will tell you that you can not..

      • I downgraded from ios 4.3.4 to 4.3.3 without SHSH blobs but it was a tethered downgrade but it is possible

      • What the fuck is a tethered downgrade..

      • how were you able to achieve this Jack? I currently have 4.3.3 and want to upgrade to 4.3.5 any ideas? thanks

        Maybe because people don’t read this stuff 24/7 like you do.

        I think you’re forgetting that there have been 100s of sources saying that exact thing for 2 years, possibly longer.

      • GOOGLE…it’s not hard…..

  • Wow… many things to do to downgrade back to 4.3.3….I’ll stick to iOS 5 now that I updated and cant go back…latest SHSH blobs saved is 4.3.5 but its tough to jailbreak on that version and I dont want to go through the process of downgrading again ugh…I’ll just stick to updating versions I’m tired now


    • Well, the program itself says that it’ll change the basband.

    What’s wrong with TinyUmbrella? Why should I use this method instead of the good old SHSH’s from Cydia/TinyUmbrella? Honestly, I don’t see the usefulness and/or the advantage of this method.

  • I got an iphone 4 here. May baseband is 4.11.08 then if i downgrade it from ios 5 to 4.3.3 does my baseband will downgrade to? Pls. Reply so that i can use my iphone 🙁

    • – It WILL modify the IPSW to update your baseband to the latest

    I need to upgrade my iPad to version 4.3 without using a computer, is that possible?

    I found out that tinycfw uses internet connection for downloading the new firmware, isnt it weird? And it takes too long time and nothing happenes,
