    If you have the saved Lockdown folder, you don’t need to install SAM again. Only insert the filder with iFunbox or SSH 😉

  • unlock solution for 04.11.08

    I am waiting over 6months now for unlocking my iPhone 4 04.11.08 locked to Three Ireland network.. Its ironic, because I used SAM for sim card owned by a company I worked for. I had to give it back few days after SAM was blocked. Now I am with my locked iPhone 4 again.. How many days, weeks or months do I have to wait again??
    Hackers of the world please, do find any solution for the stupid basebands 04.11.08 and 04.12.01 soon!!

    and install ipad bb by redsnow

    It works great!!!!

  • getmax

    you need to save the activation ticket with the latest redsn0w (more->even more-> backup!)

  • getmax

    …and then yes, you do this:

    Step 1: Locate the SIM card that was used during the initial unlock process. This is the unofficial SIM card, not the SIM that was provided by the official network.
    Step 2: Open up the iFile app on your iPhone and use it to navigate to the /var/root/Library directory. If you don’t have iFile installed, it is available as a package from within Cydia with a free limited feature trial.
    Step 3: When you are in the directory mentioned above, select the ‘Edit‘ button in the top right hand corner of the iFile user interface. When the directory is in edit mode, select the Lockdown folder.
    Step 4: With the Lockdown folder selected, press the zip button to create a compressed file backup of the Lockdown folder. Once the zip file has been created, make sure to name it something that will distinguish it and is rememberable.
    Step 5: Scroll to the bottom of the current directory and make sure that your zip file has been created and is available. If it is, then delete the entire Lockdown folder using the trashcan icon.
    Step 6: Bring up your Dropbox folders and locate the Lockdown folder that contains the valid activation ticket, created by the unofficial SIM card that was used during the unlock process. Open up the recently created zip file using the iFile app once again and select the ‘Unarchiver‘ option.
    Step 7: The contents of the zip file will now be extracted and dumped into the default directory, which in most instances is the Documents folder.
    Step 8: Once again, select ‘Edit‘ in the top right hand corner of the iFile user interface before selecting Lockdown, and press the clipboard icon which would in turn copy the Lockdown folder. Tap the ‘Done‘ button.
    Step 9: Still in iFile, navigate to /var/root/Library and select ‘Edit‘. Select the clipboard icon and then tap ‘Paste‘ before tapping the ‘Done’ button.
    Step 10: If you still have the SAMPrefs package installed on the device, then navigate to /User/Library/Preferences and search for SAM. When found, make sure to delete the com.bingner.sam.plist file if you can find it (it may not exist in some cases). The purpose of this is to make sure that everything goes smoothly without any conflicts.
    Step 11: Turn the device off, making sure that it is powered down entirely.
    Step 12: Turn the iPhone back on and wait until it loads all the way to the home screen. After the device gains a network connection, it should be with the carrier of the unofficial SIM card.

    There you go!

  • dinocorpse

    hi there, thanks for all the info, but im still abit confused. i had already saved my ticket with cookie and with redsnow and just to be sure “ifiled it to my dropbox account. now i want to know if i can update without being able to save my current baseband with redsnow,(cause i have tried this with no luck) and still be able to use my ticket on the current baseband that is being used for firmware 5.1.1. i am not sure what basband firmware 5.1.1 is using. if its 4.11.08 then i should be fine. cause thats the baseband i was able to unlock it with SAM. i hope this is clear. please let me know if not.. appreciate your help. thanks.

  • Mustafa
