    I purchased a new iPhone that was running 4.3.3 and managed to downgrade it without SHSH blobs to 4.2.1 and jailbreak it by using redsn0w, greenpois0n, and TinyUmbrella to kick it out of recovery mode whenever it got stuck. Finally, it was up and running, but whenever I turn off the iPhone it goes straight into DFU mode. From there, I can only boot it using redsn0w and the jailbreak is tethered because of that. Now, the screen is black even though the iPhone is on. Is there a way to fix the screen problem, keeping in mind that I can't do a hard/soft reset because it goes straight into DFU mode, and how can I untether this jailbreak?

    tl;dr
    Specs:
    iPhone 4
    firmware: 4.3.3 downgraded to 4.2.1
    jailbroken: yes, tethered, w/o SHSH blobs
    programs used: redsn0w, greenpois0n, TinyUmbrella

    Problems:
    Black screen but phone is on
    Jailbreak is tethered

    Solutions:
    ?????



    Thanks in advance for your time and consideration.

    I was the genius who didn't realize there was a jailbreak for 4.3.3. I confused it with 4.3.4.

    If it's in DFU mode, just do a restore to 4.3.3 and re-jailbreak. You're better off that way.

    So far I've tried:

    pwned DFU with Redsn0w to restore 4.3.3 using saved shsh blobs in TinyUmbrella.

    pwned DFU with Redsn0w to restore 4.3.3 using saved shsh blobs in TinyUmbrella, resulting in error 1013. Then I used fixrecovery43 and that also did not work. It seemed like it was working, but it froze at one point and left me in DFU mode.

    I did get it to boot tethered using Redsn0w, but then the screen went black death on me. It was still on and could receive texts and etc, but the screen was completely blank.

    Also,sometimes when I fix recovery in TinyUmbrella, it takes me to the greenpois0n initialization screen as if it were jailbreaking, and then freezes there and eventually drops down to DFU.

    Tried installing Cydia with Redsn0w, it gets to installing activation bundles and then drops back into DFU mode. Attempts to fix recovery put me into a DFU/recovery mode loop.

    When you restore, remember to set the iPhone up as new. Don't use any backup!

    Having done that, it's up and running finally. Thank you so much!
    However, I am still unable to reboot the device or turn it off without it entering DFU mode. Then, I have to boot it tethered with redsn0w. It's like its only two modes are DFU and on.

    I spoke too soon, the black screen prevails again.
    It tends to happen after I've reinstalled all the packages from Cydia that I'm used to having. Is it possible that they(combined with whatever firmware problems my iPhone seems to have) cause the black screen?

    Could be. Try restore, set it up as new and not jailbreak.

    I wouldn't recommend it. Screwed up my iPhone pretty badly.

    This is why you save your SHSH files if you wish to restore to previous firmwares without any issues.

    If you're experiencing software issues, restoring WITH backup properly won't fix your problem. Therefore I always recommend that you set it up as new, to get a clean install. Kinda like what you would do with a Windows computer.

    I appologize for the lengthy read....I just wanted to be as thorough as possible. I am not a noob at this so this is really kicking my ass. I can solve most issues with jailbreaking and unlocks, but damn this DFU mode is a bitch.

    I am having the exact same problem with my iphone 4. I will start from the top.

    I just bought an iPhone 4 on August 6, 2011. I am currently still using my iPhone 3gs until i get the Gevey unlock sim off ebay i ordered (hopefully mid this coming week). Couldnt pass up a practically brand new iphone 4 for 400 bucks. Anywho.

    Came with 4.3.3 firmware on it baseband 04.10.01.

    Sycned it with my itunes but some things were acting screwy since it was already jailbroken i decided to do a restore. It had shsh blobs saved on Cydia 4.3.3, 4.3.4 and 4.3.5. So i knew i could just stay at 4.3.3. So i put it in pwned DFU mode with pwnagetool, used TinyUmbrella's TSS Server and Restored multiple times with 1013 error and kicking straight back into DFU mode this whole time mind you. After combing the internet's iDevice forums i finally came across one that told me to check the UPDATE BASEBAND option in tinyumbrella. I had seen that option under advanced before after going into that window about a 10 different times changing crap.
    As this is my first iPhone 4 i was not too sure what the latest baseband was so i did some research and found out that it was ok for me check that as the baseband has not changed from 4.3.3-4.3.5 just the jailbreak has. So i checked it. BAM was able to get itunes to restore without the 1013 error.

    But now i was still stuck in DFU Mode loop. not recovery loop, that is one thing i have found is a lot of these forums were talking about recovery mode loop (connect to itunes icon) which i never even got once. Which did not help my case.

    So i tried to use FIXrecovery43 the file not the one in Tiny umbrella (that one doesnt do crap but get stuck at the greenpois0n menu on my iphone). And it goes through its whole process like its gonna work and nothing right back into DFU mode again. I must have done this at least 10 different times. Every time back into dfu mode.

    I tried installing cydia with Redsn0w which went through the whole jailbreak process a couple times, but right back into DFU mode, and 2 other times i tried this it stuck on the running pineapple Activating Bundles (i think thats what it was) either way whenever it was finished it would eventually go back to DFU mode.

    Got sick of that so i tried boot tethered for now on redsn0w and what do you know it booted in just fine and now my iphone works. But i have to treat it like a tethered jailbreak but a little different, this one just goes back into DFU mode if i reboot or shut it off. Its really strange and quite annoying.

    Oh forgot to mention i just updated to 4.3.5 and it worked just fine with an official apple update. Was able to downgrade back to 4.3.3 without any itunes error but guess what my good old friend DFU mode.

    So its not any software issue, my firmware is just fine and runs great as of right now. its still syncing and i restored from NEW iPhone.

    As of right now, just DFU Boot loop if i reboot it or shut it down and just use it like a tethered jailbreak, but there has to be a solution for this. Unless an untethered jailbreak comes out for 4.3.5 i am just gonna be using Redsn0w to boot it up.

    If anyone has any insight or would like me to elaborate more about something, i am all ears. Sorry for the long post but i have literally been working on this all day and i sill did not explain everything i did to a T.

    Thanks in advance.

    I know everyone over here is really experienced and smart with all jailbreaking tips and trick but i just want to ask, if you're on 4.3.3, have tried jailbreaking simply with JailbreakMe 3.0 ?

    Put your phone in stock condition (with iOS 4.3.3) and give JailbreakMe 3.0 a shot!

    Cheers!

    What if when its done restoring from ITUNES it goes straight into DFU Mode? iTunes does not even give me an option to restore, it detects the phone in restore mode, every time.

    People if your not going to bother reading the posts, then dont bother posting a crappy answer that we have tried already, or can't try due to the current condition of the iPhone. K. Thanks.

    Ok i fixed it!!! It must have been corrupted SHSH blobs from cydia here is what i did since everything i tried was booting back into DFU mode.

    Upgraded to 4.3.5, used redsn0w beta to jailbreak with 4.3.4 IPSW. Jailbroke it, booted tethered. Installed SHSHIT from cydia and downloaded my 4.3.3 SHSH Blobs and emailed them to myself. Put them in my TinyUmbrella shsh folder and restored like normal with Itunes as i have been doing (pwned dfu mode, using TSS server back to 4.3.3) and holy hell! It works!

    I am now on 4.3.3 untethered, no DFU mode. Thank you SHSHit. I could have lived with a tethered JB as i know it would not be forever, but untethered is much better.
