Redsn0w 0.9.14b2 Download Released For iPhone 3G(S) To Improve Baseband Downgrade


by cM Boy on July 5, 2012

Few weeks back, iPhone Dev Team has released a version of Redsn0w that allowed iPhone 3G(S) users to downgrade iPad baseband 06.15 to earlier versions like 05.13.04. Many users have successfully downgraded their baseband but a few of them were having issues.

Today, iPhone Dev Team has released an updated version of their software named Redsn0w 0.9.14b2 that fix all the issues users were having earlier. Download links are available at the end of the post.

This is what the dev team has posted on their blog:

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.

The revised steps are:

  • Connect your iPhone in normal mode, then click “Jailbreak” after redsn0w identifies its model and BB version (you needn’t pre-select the IPSW anymore).
  • Choose the “Downgrade from iPad baseband” option (you needn’t worry about de-selecting Cydia anymore).
  • Do a controlled “slide to power off” shutdown of your phone and proceed through the normal DFU ramdisk steps.

iPhone 3GS with basebands 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 can be unlocked using Ultrasn0w. iPhone 3GS with basebands 05.14.02 / 05.15.04 / 05.15.04 / 05.16.01 / 05.16.02 cannot be unlocked with Ultrasn0w so they have to install iPad baseband 6.15.00 on their 3GS device which can be unlocked. That was the whole story.

Now we have seen a lot of iPhone 3GS devices using 6.15.00 baseband to get the unlock. Once they upgrade to this baseband, it cannot be downgraded back to any earlier baseband. Now the question is why would they want to downgrade 6.15.00 as they are enjoying the unlocked devices on it ? Well there are few issues with the iPad baseband installed on the 3GS devices and GPS not working is one of the main issue. This is where the dev team is working right now and looks like they are very close this team for real. They will be able to downgrade 6.15 to baseband 05.13.04 or earlier version which can be unlocked without any issues.
