Downgrade 06.15.00 Baseband to 05.13.04 with Redsn0w 0.9.14b2 (Video Tutorial)


This is a video tutorial that will walk you through downgrading your iPhone 3G/3Gs from the iPad baseband 06.15.00 to 05.13.04 which is another Ultrasn0w compatible baseband that will allow you to unlock and use your GPS capabilities. It is very important that if you have a 3Gs and it was manufactured on or after the 35th week of 2011 you SHOULD NOT install the iPad baseband. Doing so will permanently brick your cell radio. You can tell when your device was manufactured by looking at the 3rd, 4th and 5th digits of your phone's serial. The 3rd digit is …

06.15.00 baseband downgrade to possibly be released this sunday!


Earlier this week, we reported that MuscleNerd had made great progress on his 06.15.00 baseband downgrade that has been mentioned and speculated pretty much since the release of the iPad baseband unlock method. Those with a 3G/3Gs who have updated to the 06.15.00 baseband in order to unlock with ultrasn0w have been dealing with GPS issues ever since. Finally MuscleNerd has everything in place for a downgrade that will let you downgrade your 06.15.00 baseband to any other earlier iPhone baseband. Today, MuscleNerd tweeted that he is aiming for a release this Sunday(funday), but as always, release dates are tentative …

MuscleNerd confirms progress on 06.15.00 iPad baseband downgrade


Well, it has probably been a year or so since the last time we heard about any progress being made on fixing the 06.15.00 baseband GPS issues plaguing iPhone 3G/3Gs users who were forced to upgrade their baseband in order to unlock. There was talk for a while about MuscleNerd creating an 06.15.00 baseband downgrade so that 3G/3Gs users who were on the 06.15.00 baseband could downgrade back to 05.13.04 which would still allow them to unlock via Ultrasn0w, but would also allow them to use their GPS once again.

There are no further details, but he does go on …

Unlock with Ultrasn0w on 5.1.1 with Ultrasn0w 5.1.1 Fixer (DEB)


For our readers who have updated to 5.1.1 using Sn0wbreeze 2.9.5, you may have noticed that even with a compatible baseband, Ultrasn0w does not work on 5.1.1. Until the iPhone-Dev Team releases an update to Ultrasn0w, you will have to install the Ultrasn0w 5.1.1 Fixer in order to get the unlock working. For your convenience, we have bundled the latest Ultrasn0w, MobileSubstrate and the Ultrasn0w 5.1.1 fixer into a single download.

The easiest way to install these deb files is to simply transfer the files to any folder on your phone using iFunBox, iExplorer or SSH and then installing the …

Ultrasn0w 1.2.5 for iOS 5.0.1 compatibility available now


The other day, we reported that MuscleNerd had announced a new version of Ultrasn0w 1.2.5 which would fix compatibility issues with iOS 5.0.1. Yesterday, we told you that the iPhone-Dev team repo had gone down which is why this new version of Ultrasn0w 1.2.5 was not released on Monday as planned. Today, it seems that the infrastructure update has been completed and now Ultrasn0w 1.2.5 is available in Cydia. Once again, I must stress that this new version of Ultrasn0w DOES NOT add any new baseband compatibility. It only adds 5.0.1 support for basebands which are already unlockable:

04.26.08 …

iPhone-Dev Team website and repo down for infrastructure update


Today, @MuscleNerd announced that the iPhone-Dev Team blog and the Ultrasn0w repo are both down due to an infrastructure update. Unfortunately, this has also pushed back the release of Ultrasn0w 1.2.5 which will add unlock support for users on iOS 5.0.1 without using the Ultrasn0w fix that we posted a while back. Please stay tuned for more updates!

Ultrasn0w 1.2.5 adding 5.0.1 unlock support to be released later today


Just a bit ago, @MuscleNerd announced the released of Redsn0w 0.9.9b9 which adds 5.0.1 native compatibility as well as a bunch of new features. One footnote you may have missed is that later today(Monday) Ultrasn0w 1.2.5 will be released to add support for iOS 5.0.1. Until now you have had to use the Ultrasn0w 5.0.1 fix in order to unlock on that firmware, with this update of Ultrasn0w you will no longer need to do that.

To be clear, this does NOT add support for any new basebands, only compatibility with the 5.0.1 firmware for basebands which have already …

How to update iPhone baseband to 06.15.00 for unlocking on iOS5


Alright, so it has come to my attention that many of our readers have an iPhone3Gs and would like to unlock their phones but are on a baseband which is not unlockable. The good news about the iPhone3Gs is that no matter what baseband you have, you can use Redsn0w to update your baseband to the iPad baseband, 06.15.00 which IS unlockable with Ultrasn0w 1.2.4 on iOS5.

*WARNING* By updating your iPhone to the 06.15.00 baseband you run a HUGE risk of losing your GPS functionality. I would say probably 9/10 iPhones that use the 06.15.00 baseband …
