WARNING: NO warranty is provided with this guide. Follow at your own risk.

A lot of info that iPhone 3GS 3.1.3 with Modem Firmware 05.12.01 can only be jailbroken using spirit jailbreak and no way to upgrade to iOS4. Here’s a full unlock of iOS4 when you’re stuck at 3.1.3 spirit jailbreak.

  1. Restore to default with 3.1.3 and JB using spirit
    (if can’t activate, then you can try without restore)
  2. Use Cydia to install the following packages: afc2add, openSSH, MobileTerminal
  3. Download Spirit2Pwn and extract
  4. Get sn0wbreeze 1.5.2
  5. Get 3.1.3 ipsw and 4.0 ipsw
  6. Create a 3.1.3 Customer firmware using sn0wbreeze. Ignore the warning (if any) and just create the firmware. We’re not going to restore using this firmware anyway.
  7. Firmware should be put on Desktop. Go to desktop and rename it to something that identify it as 3.1.3 Sn0wbreeze firmware. Also, change the extension to zip.
  8. Extract the zip file
  9. Connect your iPhone to your WiFi. Use SFTP and login to your iPhone. If you have no SFTP client, you can use FileZilla. Default username/password combo is: “root”/”alpine” (without the quotes)
  10. Copy all the files you find in “Firmware/all_flash/all_flash.n88ap.production” (from the extracted custom firmware) to iPhone’s “/tmp”
  11. Copy all the files you extracted from spirit2pwn_r2.zip to iPhone’s “/tmp”.
    NOTE: Some reports error, so you may want to make another copy of “pwn_old_boot_r2.sh” on the /tmp named “pwn_old_boot_r1.sh”
  12. Once done, SSH into the phone using PuTTy or use MobileTerminal on the phone
  13. Use the same credentials as the SFTP credentials. Then run the following commands:
    cd /tmp
    chmod 755 pwn_old_boot_r2.sh
    chmod 755 pwn_old_boot_r1.sh
    ./pwn_old_boot_r2.sh
  14. Wait for the process to say “SUCCESS”
  15. type “reboot” and let the phone reboot
  16. Download sn0wbreeze 1.6.1
  17. Create custom firmware for iOS4
  18. Use the Shift+Restore (on Windows) or Alt+Restore (on Mac) and point to the custom iOS4 firmware.
    NOTE: If you’re not using iTunes 9.2 at this point, an error (13) will be raised
  19. After complete, use Cydia and install the same packages again (openSSH, afc2add, MobileTerminal) and add another repository: http://repo666.ultrasn0w.com
  20. Find Ultrasn0w and your phone is now jailbroken and unlocked on iOS4
