      Hi, have you tried using booting tethered using tools that comes with sn0wbreeze (iBooty) or Redsn0w? As for restoring, make sure that your device is in DFU mode before you restore to minimize errors.

I do all the steps in your guide. When I do the ALT click (on Mac OSX), iTunes reads and extracts the NO_BB ipsw file, then I get the following error:”The iPhone ‘iPhone’ could not be restored.

    I have IOS 5.1.1 on my iPhone 4s, i would like to Upgrade to IOS 6.1.2, before the current update. this will still allow me to jailbreak. is there w way to install ISO 6.1.2 on my phone?

    •  
      Patrick Gumban1 year, 1 month ago

      Hi, I’m afraid there is way you can upgrade to iOS 6.1.2, only 6.1.3 where the jailbreak is tethered and doesn’t support the iPhone 4S. If you update to iOS 6, you will surely lose your jailbreak.

          Hi, unfortunately in your case, you won’t be able to update to iOS 6.1.2, only 6.1.3 which doesn’t have a jailbreak for your iPhone 4S. Even with saved SHSH blobs, you can’t update to iOS 6.1.2.

    Can i restore a blacklisted Iphone ?

    •  
      Patrick Gumban1 year, 1 month ago

      No. Restoring will not make it work. This is because the IMEI is blacklisted by the carrier. Carriers have protocols with all the carriers so that even if you could unlock the phone it wouldn’t work in the other carriers. What you can try is to jailbreak (search for quickpwn for iPhone) the phone and sell it on ebay to some other country, and there it will work (as being blacklisted only works in the country you’re at).

    Hi every one, my iPhone 4 (jailbroken iOS 5.1.1) got stucked on apple logo screen (boot loop); I tried so many things i read from the internet (i.e “just boot tethered with redsn0w, i got stucked on pineapple logo”, ” i tried all sort of methods, using Tinyumbrella, iREB, RecBoot e.t.c) but non of them worked.Here is the solution.i downloaded the latest version of iTunes, redsn0w (version 0.9.14b2) and iOS firmware 5.1.1 from apple servers (iPhone3,1_5.1.1_9B206_Restore) i installed redsn0w and opened it (you have to run as administrator when opening redsn0w); then i clicked on ‘Extras’; after that i clicked on Custom IPSW (NO_BB_iPhone3,1_5.1.1_9B206_Restore) and i selected the iOS 5.1.1 firmware and then redsn0w created a customized iOS 5.1.1 firmware preventing my modem firmware from upgrading (iPhone cannot be unlocked once the modem firmware has been upgraded by itunes)and then i put the iPhone in DFU mode by holding home and power button together for 10 seconds till the screen turned black and then i released the power button only remaining the home button for about 10seconds and then i plugged the iPhone to the computer.(redsn0w will write “iPhone 4 in DFU mode” at the bottom part) and i clicked ‘back’ and clicked ‘SHSH blobs’; and then i clicked on ‘Fetch’ (to automatically fetch SHSH blobs from the iphone and upload it to cydia server and as well save it to redsn0w folder on my desktop) after the shsh blobs has been fetched successfully, i clicked on ‘stitch’ and then i clicked on ‘IPSW’ and i selected the customized iOS 5.1.1 firmware (NO_BB_iPhone3,1_5.1.1_9B206_Restore)and then i clicked on ‘Local’ (to stitch a local blob file into the IPSW) and then redsn0w stitched my SHSH blob to the customized iOS 5.1.1 firmware and save it on my desktop; it’s something like 799233244588_NO_BB_iPhone3,1_5.1.1_9B206_Restore.the ’799233244588′ is my SHSH blobs code.i opened iTunes and it wrote ” an iPhone 4 has been detected in recovery mode, you need to restore blah blah…….. and then i clicked ok and i hold ‘SHIFT’ (on the keyboard)and clicked on ‘restore’ and then i chose the customized and stitched ios 5.1.1 firmware (799233244588_NO_BB_iPhone3,1_5.1.1_9B206_Restore) and iTunes did the rest.my iPhone is now in home-screen and my modem firmware is unupgraded.I’m using iPhone 4 GSM, 32GB, iOS 5.1.1, modem firmware 4.10.01, Gevey Sim.Things to download:iTunes, redsn0w (version 0.9.14b2) and iOS firmware 5.1.1

      Pramod2 years, 11 months ago

      NO. You need to get that power button of yours fixed first. Currently there is no way to put your device into a DFU mode w/o the Power button for any of the latest iOS 4.x.x versions.

    How do i restore using my locally saved SHSH’s vs. those saved (or unsaved) on Cydia’s servers. I had 4.2.8 jailbroken and it crashed from a bad mod (boot-loop & ‘connect to itunes’ message). I saved (so I thought) my SHSH for both 4.2.6 & 4.2.8 locally and to Cydia’s server, but when I tried to restore 4.2.8 using TU, it would get 1013 & 3XXX errors. I then used iFaith to create a custom signed IPSW, but the only SHSH it found was 4.2.6. I am now restored to 4.2.6 and re-jailbroken, but I’d like to be on 4.2.8 and have the SHSH & IPSW saved locally. I tried every variation of modifying the hosts file that i could find on google and kept getting these different errors with TU. Ifaith is great, I just wish I could point it at the IPSW and TU’s SHSH and create a custom IPSW that way (I even tried by renaming TU’s SHSH to the iFath filename/extension… didn’t work). Is there any other software that will let me do this?

    •  
      Pramod3 years ago

      If you have them saved locally, goto TU and hit the Start TSS Server button. After that, go back to iTunes and follow it up with the IPSW 4.2.8 Shift + Restore. Make sure that you keep TU running in the background during the restore.

      Pramod3 years ago

      Tiny Umbrella could have saved it locally for you as well. But if you haven’t, then I’m afraid your stuck on iOS 4.3.4 for now w/o a jailbreak.

    yes iv’e heard of that but i have the ipad 2 wifi only is there an ireb version compatible with that?

    •  
      Pramod3 years ago

      No, you don’t have an iReb for iPad2. If your looking for a downgrade of iOS 4.3.4 to 4.3.3, you need to use TinyUmbrella’s latest version.

    •  
      Pramod3 years ago

      You need to put your iPad2 first into a Pwned DFU mode. A simple DFU restore will not work. Use iReb. If your using an iPad 2 GSM/CDMA, use the latest TinyUmbrella to restore w/o any 10xx errors.

    i got a problem
    i got ipad , a friend tried to restore 4.3.3 ipsw , it works , but when i jalibreak it , it won’t work , it sticks to the boot screen and loops the boot, i hear the charging sound when im connectiong the ipad or sometimes i see the springboard with missing icons , white icons , and cut icons ! and most of them doesnt work

    anyway , i tried to downgrade to 4.2.1 , it works too ,and i can jailbreak and same problem with the icon , and if i turn off the ipad and turn it on again , it sticks to the boot screen and the loader spins !

    i checked the tethered\untethered thingy , i guess no problem ! coz i was using redsnow for 4.3.3 and greenpoison for 4.2.1

    i used both of them to jailbreak iphone 4 , ipod touch and all works like a piece of cake , but this ipad is driving me crazy !!!

    •  
      Pramod3 years, 1 month ago

      Firas, what happens when you do a fresh stock restore of 4.3.3 ? Does it cause issues ?
      Sticking to the boot screen and loops the boot = Tethered jailbreak.
      missing icons , white icons , and cut icons = Weird

      What you can do right now is to restore to a custom FW instead of jailbreaking it via Redsn0w/GreenP. To do that, use the latest Sn0wBreeze, Cook your custom FW & then restore it via iTunes. If everything goes well, you should have your iPad back up and running fine. Let us know how it goes. :)

      What is your iPhone model? Current firmware? Current baseband? To which firmware you are trying to downgrade? Do you rely on an unlock?

      •  
        George3 years, 2 months ago

        Its an iPhone 3G. 05.15.04 FW 5.09 Bootloader 4.2.1 iOS – strongly considering changing to iPad BB to unlock, as unlocking is completely necessary.

        •  
          Wolverine3 years, 2 months ago

          To jump from iOS 4.x.x to iOS 4.y.y on iPhone 3G requires SHSH blobs. You must follow this indirect path:

          1. Restore stock iPhone OS 3.1.2
          2. Restore stock iOS 4.2.1 (iOS 4.1 recommended to avoid recovery loop)
          3. Use this guide to upgrade your current baseband to iPad baseband http://bit.ly/gI22Px
          4. Use this guide to unlock your iPhone with Ultrasn0w 1.2.3 http://bit.ly/itMs7o

            George3 years, 1 month ago

            Is it absolutely necessary to use iTunes 10.1? I’ve completed every step asked for and yet when it says its fetching iPad Baseband data – iPhone just goes to black and nothing happens. Ugh

          •  
            Patrick3 years, 1 month ago

            Nops. You can use any iTunes version. Do not check Cydia option when you are fetching iPad baseband files. First jailbreak using Cydia and then choose Install iPad baseband option. Installing Cydia and iPad baseband on the same time will crash the Redsn0w and your iPhone will go into DFU loop.

    I have an iphone 3GS with iOS 4.3.1 with bb 05.16.02 and i want to unlock it, I have done all methods possibles posted on this great site but the last try i did was to downgrade to 4.2.1 and upgrade bb to 06.15.00 to unlock it but returned error 3194 and other errors like 1605 among others i dont recall and worked around all solutions posted here but with no luck to downgrade to 4.2.1 Well, what i have done is jailbreak my iphone 3GS (old bootrom) with Sn0wbreeze 2.4b1 but still with baseband 05.15.02. after this i did the backup SHSH blobs on Saurik server from cydia (i think is possible) but sure did one with Tinyumbrella with SAVE SHSHS, but still no luck, can someone please guide me on what to or what i am doing wrong???

      When you connect your iPhone to TinyUmbrella and click on save SHSH button, do it displays SHSH blobs of iOS 4.2.1? Error 3194 signals missing SHSH blobs.

        I am not really sure, I would have to check in my home pc (@ work this momment)when i did the save SHSH button with tinyumbrella my iphone was on iOS 4.3.1, does tinyumbrella saves a SHSH blobs of iOS 4.2.1? even if my iPhone is on iOS 4.3.1? I am guessing that i had to do the SHSH blobs backup on Saurik’s Server with the iOS 4.2.1? Or that is the point of Tinyumbrella to download a SHSH blob of iOS 4.2.1 so i can do the downgrade?
        Please get me out of all these doubts, because like i wrote before unfortunately i got my iPhone 3GS with iOS 4.3.1 an bb 05.16.02. and i really need to unlock it.

        Thank you so much Wolverine for your reply!!!

          Yes, when you click on Save SHSH button in TinyUmbrella, it downloads all of your SHSHs from Saurik’s server to your hard-drive locally. If you do not find any SHSHs in TinyUmbrella after clicking on Save SHSH button, it means you do not have SHSH on Saurik server and Apple have stopped signing the ECID of your iDevice for that particular firmware.
