I am on activation screen of 6.1.6 with baseband 6.15.00. The problem with these steps is that my power button doesn't work and so I created a custom IPSW of 5.1.1 as specified in https://www.iclarified.com/entry/index.php?enid=23009 for putting the phone in DFU mode. Will I be able to use that ipsw to put the phone in DFU mode and downgrade it as specified in this tutorial?
You can downgrade only if you have baseband version 06.15.00 (NOT 06.15.05 or like that). If you don't have that you have to first jailbreak with "Install iPad baseband" from redsn0w to get exactly 06.15.00. Then you can jailbreak with "Downgrade from iPad baseband" and then it will work! :)
Whatever I do I am unable to downgrade the baseband for my iPhone 3GS running iOS 5.1.1 from 6.15.00.
Have tried all steps on all forums. Its been 4 days I have been trying continuously....
