The iPhone Dev Team is happy to announce a baseband downgrade option in redsn0w for those who are using the iPad's 06.15 baseband on the iPhone3G or iPhone3GS. Typically you'd have the 06.15 baseband if you unlock with ultrasn0w but updated your iPhone baseband past 05.13.04. With this new capability, you can now downgrade specifically from 06.15 to 05.13.04 (even if you never had 05.13.04 on that device before). This gives you the best of both worlds: ultrasn0w compatibility and a normal iPhone baseband with full GPS and the ability to use stock IPSWs again. Here are the steps: 1.Use the "Extras-Select IPSW" button in redsn0w to tell it which firmware version you have installed (new-bootrom 3GS users can usually skip this step but it doesn't hurt for them to do it too). 2.Do a controlled shutdown of your iPhone ("slide to power off"). This step is very important to avoid mount problems when the ramdisk is running! 3.Go back to the first screen and click "Jailbreak". Enable the "Downgrade from iPad baseband" checkbox, disable Cydia if you already have it installed, and click Next to proceed through the normal DFU ramdisk steps. If you have any questions or comments, please use our comments section below! Here are the download links. Enjoy! •redsn0w 0.9.14b1 (www.mediafire.com (OS X) •redsn0w 0.9.14b1 (www.mediafire.com (Windows — run in Administrator Mode) |
