New Redsn0w 0.9.14b2 iPhone 3GS 6.15 Baseband Downgrade Released

Redsn0w 0.9.14b2 Updated To Fix iPhone3GS 6.15 Baseband Downgrade - Download Now

The iPhone Dev-Team has just announced Redsn0w 0.9.14b2 which is an update to the existing version of redsn0w that allows users to downgrade the iPad 6.15 baseband. Following the issues with various iPhone3GS users, musclenerd has looked into it and finally released an update to the Redsn0w. The new Redsn0w should fix all downgrade issues and will also help users with broken iPhone buttons to enter DFU mode without having to follow the button instructions.

The iPhone Dev-Team has also provided the revised steps to successfully downgrade iPhone3GS 6.15 baseband. It goes like this:

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.

IMP : iPhone3GS which were manufactured in early 2011 are not compatible. They have a NOR chip that cannot be upgraded to 6.15 and trying to flash the iPad baseband will brick your device.

DFU IPSW

This version of Redsn0w is much relieving for those iPhone users who have their buttons broken and cannot enter the DFU mode following the general instructions. To enter DFU mode on a broken iPhone:

1. Launch Redsn0w
2. Go to   Extras->Even More>DFU IPSW 
3. Select the ipsw that is currently been signed for your device or for which you have shsh blobs saved.
4. Redsn0w will create a ENTER_DFU IPSW that you can install with iTunes and once the installation is complete you'll enter into DFU mode.

Updated Redsn0w iPhone3GS 6.15 Baseband Downgrade Tool To Release Today - Musclenerd

Updated Redsn0w iPhone3GS 6.15 Baseband Downgrade Tool To Release Today - Musclenerd

New Redsn0w Announced : Download

A week ago, Musclenerd from the iPhone Dev-Team confirmed that there is a third kind of flash NOR that caused problems for some iPhone 3GS users when trying to downgrade the iPad 6.15 baseband. This resulted in redsn0w showing that baseband downgrade was successful but when the iPad reboots after baseband downgrade attempt, the baseband was unchanged. After quite a  lot of research musclenerd via twitter confirmed that an update to redsn0w will be released to fix all the errors. He also confirmed that changing the payload would fix the issue.

Today Musclenerd announced over twitter that an updated version of Redsn0w iPhone 3GS baseband downgrade tool would be released. This updated version of redsn0w will work on those devices which were unable to downgrade the 6.15 baseband. However, musclenerd has also confirmed that this version of redsn0w will not support those devices which could not initially get 6.15 baseband ( newer devices ). He mentioned that the revised payload seems to work fine on the devices that were unable to downgrade earlier.

Here is what he said:

Musclenerd claims to have found a way to change the IMEI of the iPhone3GS. According to him that was the reason causing iPhone users to have no signal because of no reason and the only plausible reason was IMEI. Changing that would apparently fix the signal issue. Also, IMEI changing is considered as illegal in many countries and is punishable by law. The iPhone Dev-Team will not and never release any tool that allows unethical behavior and beaks any laws. When asked if the IMEI changing tool would be released, musclenerd simply mentioned that it is illegal in many countries to change the IMEA and that it would be a bad idea to release such a tool.

Musclenerd Talks About iPhone3GS 6.15 Baseband Downgrade Failure

Musclenerd Talks About iPhone3GS 6.15 Baseband Downgrade Failure

Update : Happy 4th July - Updated Redsn0w To Fix Errors Releasing Today

Earlier this week, the iPhone Dev-Team announced the release of updated Redsn0w that allowed iPhone3GS and iPhone3G users to downgrade their baseband from that of iPad's 6.15.00 to 5.13.04 allowing them to unlock their device using ultrasn0w and getting back the GPS for iPhone3GS users. Redsn0w worked for some but many users faced difficulties in downgrading the baseband. Even after the process completes the baseband for a majority of people was still 6.15 which indicates that Redsn0w actually din't downgrade the baseband to 5.13.04.

Many troubleshooting methods were discussed but eventually there wasn't any optimum solution available to downgrade the 6.15 baseband. Senior members of iPhone Dev-Team even suggested of performing a fresh restore and then reflashing of 6.15 baseband and then attempt to downgrade. This did not help either.

Musclenerd Confirms Redsnow Update

Musclenerd today announced on twitter that he has discovered the reason for baseband downgrade failure in many iPhone3GS. According to him, the reason for failure of baseband downgrade is because of variation in NOR chip which can be changed to handle the differences between the NOR chips. There are altogether 3 types of NOR. Two are very similar and the third one is entirely different which was left out in the Redsn0w. Lastly Musclenerd clearly mentioned that he needs a loaner iPhone3GS which he'll be getting by Thursday and once the testing is done, a redsn0w update will be pushed that will allow all iPhone3GS users to downgrade their baseband without any errors. Hopefully by the end of next week every iPhone with 6.15 baseband will be successfully downgraded.

To Wrap Up

• Reason for baseband downgrade failure was variation in the NOR chips
• There are 3 different models of iPhone3GS with different Nor chips.
• Two of them are similar but the third one is entirely different, probably the one left out in Redsn0w
• Musclenerd confirmed an update to Redsn0w next week after Thursday.

FAQ


Q) How do I check if my iPhone is supported or not
A) If redsn0w 0.9.14b1 din't work on your device, its better to wait until next week for redsn0w update

Q) Will the updated redsn0w support all iPhone3GS models ?
A) Hopefully, yes. After reading RCE of Apple's 3GS flashers for a while, musclernerd observed that there are not 2 but 3 NOR chips.

Q) What is this NOR chip ??
A) NOR flash memory is used to store configuration data in iPhone.
