    Default iPhone stuck in DFU Black Screen

    Hello,

    My iphone 4 is stuck in DFU mode and black screen. This happened after a few things i tried to do. First, I upgraded from 4.1 (I do not remember the bb) to 4.3.5 and had a tethered JB using Redsn0w. I did not like the tethered option so I downgraded back to 4.3.3 using Tiny Umbrella and my saved SHSH blob that TU had listed (4.3.3 8J2). I successfully downgraded and had a working phone, but after trying to JB with a custom IPSW I created w/pwnage tool, my phone has been stuck in DFU/black screen.

    1.) If I put my iPhone 4 in DFU mode using Redsn0w and try to restore w/custon 4.3.3 IPSW created w/pwnage tool, the iphone will go through the enitre process and iTunes says my iphone has been restored, but then quickly gives me another message saying my iphone is in recovery mode (iPhone is back to black screen at this point).

    2.) If I try to restore my iPhone with just 4.3.5 Apple IPSW from iTunes (I put my iphone into DFU using Redsn0w), I get either a 1600 error or 1013 error. The 1600 error comes after iTunes goes through the entire process of restoring, and the 1013 error comes very quickly, right after it tries to start the restore process.

    this is what TU has in the log now (before it listed all my saved SHSH blobs, but now my phone is not recognized):

    09/06/2011 12:26:50.098 DFU Device connected 09/06/2011 12:26:50.172 Loaded History... 09/06/2011 12:26:52.800 Caching shsh files... 09/06/2011 12:26:52.805 Found [0] shsh files to cache... 09/06/2011 12:26:52.809 Cached [0] shsh files 09/06/2011 12:26:52.813 You are using the current version of TinyUmbrella. 09/06/2011 12:26:58.361 Attempting to fix recovery... 09/06/2011 12:27:16.840 Starting fix recovery sequence... 09/06/2011 12:27:16.848 DFU Device disconnected 09/06/2011 12:27:16.853 DFU Device connected 09/06/2011 12:27:16.859 DFU Device disconnected 09/06/2011 12:27:16.868 Recovery Device connected: 012430002128531 09/06/2011 12:27:16.898 Fix Recovery has finished. Allow device to reboot!

    Try clicking on "start TSS Server" in TinyUmbrella, then put the phone into pwned DFU mode (with pwnagetool or with redsn0w) then start the 4.3.3 custom IPSW restore again.

    That should work (assuming you REALLY do have the correct SHSH blob for 4.3.3 cached locally)

    I do click on that, but still get nowhere. I know I saved my SHSH blobs, but how can I check if they are still there? My TU log has been listed in original post.

    My phone was fine until I tried to load a custom IPSW file created w/pwnage tool.

    Are you sure you saved SHSH blobs for this phone? Did you possibly get the phone repaired at an Apple store AFTER you saved the SHSH blobs? Apple replaces rather than repairs phones, so you would need NEW SHSH blobs that suited the current phone. Your symptoms point to the fact that you DON'T actually have valid SHSH blobs.

    The TinyUmbrella log is not very useful in your case as it doesn't mention the device ECID
