iPhone 3GS - go from 05.15.04 to 06.15?

[mitsitsad]

Hey all

I have an old bootrom 3GS with SHSH blobs saved for 4.1, 4.2.1 - the phone was updated to 4.2.1 and the BB was upgraded to 05.15.04 therefore unlock is gone...

i am able to go back and forth between firmwares using tiny umbrella, but cannot get the phone to restore to 4.1 or 4.2.1 to include the 06.15 baseband.

is the phone stuck on 05.15.04 or is there a solution to this???? thanks in advance

You can upgrade to 06.xx.xx because as you see 6>5. Your iphone is not ''stuck'' and there is a solution !

Now its time to introduce you to my best friend.

turns out the more recent versions of redsn0w does not give iphone 3gs users the option to upgrade to an ipad baseband. to do this i use version 0.9.6b6 - but thanks for the help - hopefully this thread will help others who must be too lazy to use google right?
