    Default Iphone 4 stuck in dfu mode/blank screen
    Hi,
    my phone was working fine before till i messed up with it to install "H1siri" the process went through smoothly and in the last i reboot my device so its stuck in dfu mode, i tried every possiblity to make it work but no luck, last i had IOS 4.3.3 in my iphone so i tried to upgrade to 4.3.5, 5.0 but no luck, i tried all kick out recovery tools, tiny umbrella, irecovery, redsnow, recboot, recovery fix, but there's no luck restored/upgrade process went smooth always and i can see the itunes detect the phone sometime in recovery mode and some time asking for activation sim, always hear *beeping* means phone start/stop whatever, i pretty much tried everything now im so frustrated and couldn't find anything to make it work,
    i use tinyumbrella/hosts file both method, but no luck, i don't have 4.3.3 shsh blobs on cydia but i do have locally which i save with "ifaith" just for 4.3.3, if is there anyone who can help me out that would be great, im so frustrated guys with this stupid thing, i spend more than 4 days but still im not able to make it work.. all help will appriciated.

    thanks,

    Use your 4.3.3 Ifaith blob to create a signed ipsw from Ifaith software , put iphone into pwned dfu and restore to it through iTunes

    If you don't rely on Gevey Sim, restore to stock 5.0.1 to get it up first then downgrade using ifaith.
