If you have been keeping the updates regarding your favorite jailbreak tools, you should know well by now that Redsn0w has been updated to accommodate 06.15.00 baseband downgrades. After much long wait, iPhone 3GS/3G owners can now finally liberate themselves from the buggy 06.15.00 baseband. But the solution is far from perfect and the iPhone Dev-Team also shares the same sentiment. And this is why Redsn0w has been updated once again in an attempt to improve the baseband downgrade feature.
While there are users who were able to successfully downgrade their device, there are still those who can manage to using Redsn0w 0.9.14b1. And thus Redsn0w 0.9.14b2 is now available for Mac and Windows. As stated in the iPhone Dev-Team blog, the new Redsn0w version will now cover three different types of NOR chips in the iPhone 3G and 3GS. As opposed to the earlier version which only covered "the most prevalent NOR chip". Redsn0w 0.9.14b2 has also simplified the process of downgrading and added a new log feature.
iPhone Dev-Team also included the new steps for downgrading:
- 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.
With the new log feature, users will now be able to grab a log of their downgrade process just in case it doesn't work. To do this:
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.
One of the most common problems that people encounter when jailbreaking their device is the fact that their iPhone home / power button are busted or not functioning properly. This prevents them from launching a DFU ramdisk. With Redsn0w 0.9.14b2, users will now be able to enter DFU mode provided that it is healthy enough to restore to a normal IPSW. To do this, go to Extras > Even More > DFU IPSW and browse for the IPSW that is being used on your device. Redsn0w will proceed to create an “ENTER_DFU_” version of the IPSW which will dump you into DFU mode at the end of the restore process.
