Updated Redsn0w iPhone3GS 6.15 baeband downgrade released 4th July Redsn0w direct download links iPhone 4GS 6.15 updated redsn0w baseband downgrade download.

 

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:

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. 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: Launch Redsn0w Go to   Extras->Even More>DFU IPSW  Select the ipsw that is currently been signed for your device or for which you have shsh blobs saved. 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. Redsn0w 0.9.14b2 Download Links

Updated Redsn0w iPhone3GS 6.15 Baseband downgrade tool releasing today musclenerd iPhone dev-team New redsn0w to downgrade iPhone3GS 6.15 baseband iPhone 3GS 6.15 baseband downgrade tool redsn0w updated 4th july...

 

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.
