Download Redsn0w 0.9.14 B2 to Downgrade 06.15 Baseband on iPhone 3GS and iPhone 3G

redsn0w 0.9.14b2

Redsnow 0.9.14 b2 is now available for download. It actually improves the 06.15 downgrade process on iPhone 3GS and iPhone 3G users. It now removes the “downgrade failed” error message the users were getting with previous version of Redsn0w.

Moreover, it also simplifies the iPad 06.15 baseband downgrade process. Now you don’t need to pre-select the iPSW you have installed on your device. You can also leave the “Install Cydia” option checked while using this new Redsn0w 0.9.14 B2 version.

According to MuscleNerd:

Happy 4th of July!  Today’s release of redsn0w 0.9.14b2 improves the iPad baseband downgrade and should cover anyone who couldn’t downgrade with 0.9.14b1.  This version covers 3 different types of NOR chips in the iPhone 3G and 3GS (the earlier version covered only the most prevalent NOR chip).  We’ve also simplified the process and added logging to help diagnose any remaining stubborn iPhones.

Should the downgrade fail to take, feel free to leave the redsn0w log in the comments below.  Use the “Extras->Even more->Backup” button to grab a copy of /var/mobile/Media/redsn0w_logs, then extract the log text file(s) from the zip and paste them into the comments (currently that log file is generated only during baseband downgrade runs).

NOTE: The original warning about 3GS units manufactured in early 2011 or later still holds!  They have a NOR chip that’s incompatible with 06.15.00 and so trying to install it will brick the device.  Please read and re-read the warning note present at the bottom of our earlier post.

Step 8: Once completed, your device will reboot and you’ll get the signals back.

Troubleshooting:

The device is still showing the same iPad baseband.

Repeat the above method once again and make it sure you follow all the steps properly.

There are no signals after downgrade.

Remove and reinstall Ulrasn0w from Cydia. Reboot your device after you reinstall Ultrasn0w.

GPS is still not working properly.

Reboot your iPhone and wait for 10-15 min to get the signals. You can also try this old trick: SSH into iPhone and issue
killall -9 locationd; rm -rf /var/root/Library/Caches/locationd

Cydia is not working after I downgraded the baseband.

Reinstall Cydia using this latest release of Redsn0w.
