    Default Iphone 4 stuck in DFU mode after restoring to custom 4.2.1

    Hi, like the title says, i have this iphone 4, itunes was not activating it because it seems at if it wasnt from the US, i live in NY, so i plugged it to Tiny umbrella to see the version, which was 4.2.1, i made a custom, activated 4.2.1 with pwnage tool since i don't know who is the carrier and so itunes could activate the phone, put the phone in pwned DFU mode with redsnow *** had no shsh blobs saved***, ran the tss server on tiny umbrella, the restore went thru completely and when it prompted that the phone was going to restart it went back to DFU. Any solutions??? Besides restoring to the latest stock 4.3.5, anyway i can go to 4.3 or 4.3.3 or even back to 4.2.1, remember i dont know who the carrier is or i would bought a sim card without service just for activation with itunes.

    This is a dangerous combo (limera1n pwned DFU restrore of custom IPSW plus no saved SHSH blob)

    All you can do is restore to an OS that you have signed blobs for (if that is only 4.3.5 than that is your only option)

    The device will "tether boot" via redsn0w but reports are this is unstable/unreliable anyway.
