As promised by dev team, Redsn0w 0.9.14b2 has been made available intending to fix the 06.15.00 baseband downgrade issues which users were facing with the first edition of the same tool. In addition to the fixes, they have also added a new option to it helping users to overcome hardware issues with their devices.
After Redsn0w 0.9.14b1 was out, several users reported that the baseband downgrade was not properly working on their iPhones. The reason was that the first beta covered only the iPhone 3G/3GS having a specific type of NOR chip in them. So, the others were not supported. Redsn0w 0.9.14b2 adds support to other chips too, hence solving that problem. From now on, in normal cases, the baseband downgrade should work.
At the start of the post, I mentioned about a new feature added to Redsn0w to solve the ‘hardware issues’. The ‘hardware issues’ relates to the improper functioning of the power and home buttons, which you will need while entering the DFU mode. Users having trouble with that, will no longer have to worry. You can get the correct knock on entering the DFU mode with the ‘DFU IPSW’ option in the ‘Even More’ section under ‘Extras’ if you are facing trouble with your buttons.
For the downgrade process, you wouldn’t have to choose the ipsw now, unless you are using the ‘DFU IPSW’ option. Newbies will be having some confusion, just do as said below :
1. Take a backup of your data in iTunes.
2. Keep your iPhone 3G/3GS connected via USB and click the ‘Jailbreak’ button. You can skip the ipsw selecting step.
3. Don’t forget to select the ‘Downgrade from iPad baseband’ option and move forward.
4. Now Redsn0w will guide you to enter DFU. Do as it tell you and wait.
Note for people using ‘DFU IPSW’ option: You will have to select your current ipsw file if you using this option.
