    Just to let everyone know before we start that I have been Jailbreaking for years and I am very knowledgeable so you don't have to dumb up the answers for me. :)

    I have run into a problem I have never experience before and have tried everything in my power to fix it. I'm stumped!!

    I have an iPhone 3GS running ios 4.3.3 stuck in DFU mode. I can turn it on using a tethered boot but I'm trying to make the boot un-tethered. This started when my friend accidentally updated his phone to 4.3.5 and wiped off the jailbreak then did a tethered boot to get it back up and running.

    I have tried the following...

    Custom Firmware 4.3.3 instillation
    iREB RC4
    recboot
    tinyumbrella

    None of these get the phone out of DFU mode and can fix the recovery. Even after I installed the custom firmware from scratch the phone goes back into DFU mode.

    I know I'm missing something small and stupid here but I can't for the life of me figure it out. HEELLPP!

    Thanks
    Jeremy

    Do you have shsh blobs for 4.3.3 if not you can't install it. Brcause apple is no longer signing 4.3.3 you will have to stick with 4.3.5

    Or you can go to 4.1 to have untethered jailbreak. Otherwise, you will have to stuck with 4.3.5 like Labman said and it will be a tethered jailbreak only.

    I wasn't aware I need shsh blobs to do a Custom Firmware upload. Can I not use the custom firmware without shsh blobs?

    shsh blobs are needed in some form for EVERY restore, no exceptions.

    If you go to the current firmware issued by Apple they can provide it for you there and then during the update/restore, but if you want to go to anything older then you will need to have these saved yourself.

    If you don't have any saved then you're SOOL, sorry.

    About custom firmware... if you use the latest redsn0w you can bake your shsh blob into your custom firmware so you don't need it saved seperately... but you still need the shsh blob and the firmware will only work on the device that the shsh blob belongs to.

    I forgot to mention that this phone has the iPad baseband installed on it.

    Okay, well I figured 4.1 was better than tethered so I did the 4.1 restore in itunes. Got error 1015, went and ran redsn0w RC16 on it to install cydia and WALA!! BACK INTO DFU MODE! GRRRRRR!! What am I missing?

    ----------

    Forgot to mention one thing, out of desperation I decided to just hit the update button in itunes since nothing else was working. I figured I would just start over! When the upload is complete and itunes says the phone has been restored to factory settings, it goes back into DFU mode, again!

    Fix 1015 error first with tiny umbrella, the jailbreak it.

    ----------

    For some reason, Apple is still signing 4.1 for 3GS. So, you don't need SHSH blobs to downgrade to this firmware.

    When you see 1015 error. Close ITunes, open tiny umbrella, hit exit recovery. Your phone will boot up normally and will bring your phone to emergency call screen.

    (Amended) Sorry didn't realize you said exit recover instead of fix recovery. You were correct it worked, thank you. Although now for some reason I cannot connect to wifi to get cydia up and running, AND the battery mysteriously went from full to dead, lol. OMG!

    Crystal I have tried this already, after the install from itunes it just goes back into dfu mode. thats all it ever does, tinyumbrella cannot run fixrecovery for a phone in DFU mode, can it?

    Thank you guys, and girls... Got it working on 4.1, I was not aware that 4.1 was now signed so thanks for that, I could have saved 20 hours if someone had told me that before, lol. One last question, cydia is saying "unable to load, the certificat for this server is invalid) I can't remember what that means? Should I just reinstall cydia?

    Look before i ask...I know. Wrong date and time, nevermind. Thread Closed.
