    Hi guys

    I managed to restore my iPhone to 1.0.2 using iBrickr and iTunes. After that I used iBRickr to Jailbreak it... and copied the lockdown file to the correct directory and thus activating it. Then I used WinStaler to install terminal app since PXL wasn't working for me. To do that you must download terminal app folder and then use Winstaller to send it to your iPhone. Now I'm back in the iPhone jailbroken, activated and with terminal. I copied all files from BSD system manually using iBrickr because it didn't install with PXL either.

    Now I can run iunew and I get this:

    Resetting the Baseband...Done
    Opened: /dev/tty.debug
    iUnlocker: tool by geohot
    Modified to erase
    Spamming AT, waiting for a response
    Attempting to read[1]...c0
    Connected established to bootrom
    zsh: bus error iunew

    I don't have TP on.. was running to see if I got to the TP failed part. Will this work with TP on or do I have something missing already?

    Thanks

    Hi

    A friend of mine has a OTB112 that he accidently upgraded it to 1.1.3. I just want to know if it is still possible to do a testpoint downgrade bootloader?

    this problem is new to me, have done unlock from iphones 1.02, 1.1.1, 1.1.2 and OTB 112 with stealthSim.

    Would an OTB1.1.2 upgraded to 1.1.3 and StealthSim work? or do i need a jailbreak 1.1.3?

    thanks

    chesnab: No, if you upgrade an OTB 1.1.2 to 1.1.3 you must wait for 1.1.4 to be released before you can do anything to the phone part (you can downgrade and use as ipod though).

    I got someone confirming that it works now, so i think yes.

    I think this error means that there are missing/incorrect files. Are you sure that the correct testcode.bb is in the same directory as iunew?

    yes. you should be able to downgrade to 1.1.1 and activate/jailbreak as normal. then virginize the phone. then proceed with the unlocking guide.

    not sure about your stealthsim question though.

    GeeZuZz, aglitch, thanks for the info. I guess my friend has to wait a bit longer.

    i opened that phone, it was the first time opening that one - i am going to try my hand at the hardware downgrade before sacrificing another

    now looking in the drawer of the dead iphones - i can show you the phones that were sacrificed learning how to open phones..

    One question about actually opening the iPhone itself. When you are busting it open, I'm guessing your tools are making various dents and gashes on the unit?

    I want to do this HW unlock, and I'm pretty confident on doing it, just I want to open the iPhone as neatly as possible making very little marks on the unit. If there are a lot of visible marks on it, I don't know if I still want to continue with the mod. :S
