Thread: iPhone 3g wont turn on after DFU mode

  1. #1
    Default iPhone 3g wont turn on after DFU mode
    I used snowbreeze to unlock and jailbreak it, and during the last step it had me put my phone into DFU mode. I did so. Now what? Why are there no steps after DFU mode? I thought my iphone 3g was supposed to be unlocked/jailbroken and usable after this. What am I doing wrong?

    I am using 3.1.3 btw

    hi,

    Sn0wbreeze is just a custom firmware right? As i know its not for unlocking. Its just for jailbreaking a custom 3.1.3 but lower modem version. You can unlock that bu using blacksn0w or Ultrasn0w.

    restore again to an original version 3.1.2 for that is 3g. then just jailbreak/unlock it with rc3.

    Is your Iphone jailbroken at 3.1.3 using cfw or you are at stock 3.1.3 ? If you are at stock apple 3.1.3 fw, you are screwed , the baseband for 3.1.3 cannot be unlock at this moment.

    LEAVE ME A MESSAGE ON MY INBOX.

    your phone is factory unlock? or LOCKED? if locked then use blackra1n or rc3 to unlock it, enable your wifi ok? more question drop it here.

    It is LOCKED. I got it yesterday.

    Ok so I just found the ISPW file on the desktop created by snowbreeze. I had no idea. Snowbreeze never told me that it created a custom firmware for me on the desktop. I saw it by coincidence. Jesus I wish they would just say that from the start!!

    so do I just go to itunes now and restore my iphone with that custom firmware? theres no directions after the DFU mode from snowbreeze

    I tried restoring the iphone with the custom firmware and I got an error message saying "The iphone could not be restored. An unknown error occurred (1600)."

    hi,

    don't update it to 3.1.3 for it will also update your modem and you'll get a no service phone. Restore in 3.1.2 only and activate it by the original sim carrier then run blackra1n for jailbreak and unlock.

    If you have already restored to stock 3.1.3 , there is no unlock because you upgraded your baseband.

    Assuming you haven't done the above,

    and you are already jaibroken, only then you can restore to custom firmware, do a Shift key + Restore (Itunes) and browse to the SnowBreeze you created.

    If 3.1.3 and modem is 5.12 there is no way to unlock it, you can use that as an iPod only (no service), use redsn0w to jailbreak it.

    Here are some tools you will use...

    Ok, now your only option is to get out of emergency screen to Home Screen, if you have not done so, you will need the official sim card to do that.

    Assuming you are at home screen, run spirti jb and you can now use it as an Ipod Touch if you are not on Official Carrier.

    I do have the original ATT sim card but not sure if it's still activated. Pretty sure it's not.

    How do I get to the home screen? I dont want to use it only as an ipod touch. Can I use it as an unlocked and jailbroken iphone?

    anybody want to help me out? id appreciate it!
