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.
