[TUT] Downgrade BB 6.15 to 05.13.04 on iPhone 3G/3GS using the latest Redsn0w. - PINOYDEN

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:

1. 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).

2. Choose the “Downgrade from iPad baseband” option (you needn’t worry about de-selecting Cydia anymore).

3. Do a controlled “slide to power off” shutdown of your phone and proceed through the normal DFU ramdisk steps.


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 in our earlier post.



For those who are wondering if you can update your 3G or 3GS to 06.15 solely for the purposes of downgrading to 05.13.04, the answer is “yes” for 3G owners, and “maybe” for 3GS owners.  The iPad baseband is not compatible with 3GS units manufactured week 34 of 2011 or later.  If you have an iPhone3GS and if digits 3-5 of its Serial Number are 134 or later (xx134…), then you should NOT try to install the 06.15 baseband on your 3GS! It will brick your radio, preventing both the downgrade from working and normal iPhone software from using it as a phone!  Be warned!

This is no guarantee that he will indeed release the downgrade this Sunday, but it sure is promising at this point.

sir ano difference/advantage kung maddowngrade ko yung bb 6.15 ng iphone3g ko?

Gagana na ulit GPS ng iPhone 3G mo.

ay ganun pala yun.
high tech na iphone ko kung ganun.haha.sige sir wait ko yan.

.meron po bang pang iPhone 4G na downgrade ng BB?

As of the moment 3GS with BB 6.15 only.

Redsn0w 0.9.14b1 released to downgrade BB 6.15 to 05.13.04

tol pag nagdowngrade ba ako kailangan pang jailbreak ulit tapos maoopen line padin siya kahit hindi na 6.15 yung bb?

Di na kailangan, punta "Extras" select IPSW ka lang tapos load mo yung IPSW na gamit ng iPhone mo tapos "Back" then "Jailbreak". Uncheck mo lahat except “Downgrade from iPad baseband” tapos next. Follow mo lang on screen instructions for dfu. kapag nagkaproblema ka sa signal, reinstall mo lang mobile substrate at ultrasn0w.

Magiging 05.13.04 baseband ng iPhone mo which is still unlockable via ultrasn0w.

Note: some of you might experience difficulty in downgrading the ipad baseband or might not be able to do so. Don't worry, MuscleNerd already has a fix and it will be released as an update on redsn0w on Thursday.
