This tutorial will teach you how to modify blacksn0w to be compatible with 3.1.3 firmware but it is addressed DONATE the owners of iPhone 3G / 3GS who 3.1.3 firmware si baseband 05.11.07. This tutorial IT WILL NOT WORK cu baseband 05.12.01 in no way, so there's no point in asking.
Follow this tutorial OWN RISK! I haven't tested it because I don't have it baseband 05.11.07 ci 05.12.01 so I don't know if it works or not, those who tested it confirmed that it works, it depends on your attitude.
Step 1
Download the 2 blacksn0w files from here: [download id=”1,36″] and 7zip from here and install it.
Step 2
Connect to your phone using ifunbox and enter the file / tmp / from the phone.
Step 3
Open 7zip and navigate to where you saved blacksn0w.deb and enter it until you reach System\Library\LaunchDaemons\com.apple.CommCenter.plist and copy com.apple.CommCenter.plist in the phone in the file / tmp /.
Step 4
Copy the file blacksn0w.dylib, downloaded in step 1, into the directory / Usr / lib from the phone.
Step 5
Install mobile Terminal from Cydia, open it and type su then type as the password Alpine, if you have previously changed the password, enter the new password.
Step 6
After logging in as an administrator through the Mobile Terminal, write this command in the Mobile Terminal: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist ; launchctl load /tmp/com.apple.CommCenter.plist ; launchctl start com.apple.CommCenter
Now check if the phone has completely lost the signal, if it is not possible for the phone to lock, wait about 20 seconds and then reset the phone by simultaneously pressing the Home+Lock keys until the Apple logo appears on the screen.
Step 7
If everything went ok and the phone lost the signal, then copy the file com.apple.CommCenter.plist folder / tmp /, from the phone, also in the phone in the folder System/Library/LaunchDaemons/.
Now reset the phone by simultaneously pressing the Home+Lock keys until the logo appears Apple Lossless Audio CODEC (ALAC), on the screen.
After the reset you should have a signal and everything should work ok.
