Improvised version of Redsn0w 0.9.14b2 has just been released and is available for download for both Windows and Mac. The latest version 0.9.14b2 of Redsn0w jailbreak improves the iPad baseband downgrade process and allows anyone who couldn’t downgrade with Redsn0w 0.9.14b1 earlier. The most vocal member of iPhone Dev Team @musclenerd clarifies that this version covers three different types of NOR chips in the iPhone 3G and 3GS (the earlier version of redsn0w covered only the most prevalent NOR chip).
The process for downgrading the iPhone 3GS/3G baseband is fairly simple and the added logging process will help hackers diagnose issue, if any. In order to get the log, 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. All you have to do is to leave a comment below detailing the exact issue and we’ll get in touch with iPhone Dev Team for next steps.
How to Downgrade iPhone Baseband
- 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.
NOTE: iPhone 3GS that are manufactured in early 2011 or later have a NOR chip that’s incompatible with baseband 06.15.00 and so trying to install it will brick the device. Before you start downgrading your iPhone baseband, be sure to re-read the warning issued by iPhone Dev Team.
In addition, Redsn0w 0.9.14b2 comes with a new feature for those who can’t launch a DFU ramdisk due to broken home/power buttons. With this new feature you can enter into DFU mode without jailbreak as long as your phone restore to a normal, everyday IPSW. This feature creates an IPSW that will cause the device to enter DFU mode at the end of an otherwise normal iTunes restore.
To accomplish it, navigate to “Extras->Even More>DFU IPSW” and select an IPSW that is currently being signed for your device. Redsn0w tool will create an “ENTER_DFU_” version of the IPSW that you can restore easily onto your device, except that now you’ll be dumped into DFU mode towards the end of the restore.
