I have an iPhone 3G with iOS 4.2.1 and baseband 05.15.04. I want to upgrade baseband to iPad version 06.15.00, hence I can unlock it with Ultrasn0w.
I have tried these methods on both Windows XP Pro SP2 32-bit and Windows 7 Ultimate 64-bit. I have tried "run as administrator" and "set affinity to 1", but with no luck.
For now, my iPhone becomes an iPod touch. I don't have a Mac, and I don't know what to do next. Any ideas?
You have to use Redsn0w to install the ipad baseband, 0.9.6rc14 is ok, or Pwnage (Mac), not sure if Sn0wbreeze supports the install or not, but hopefully you have weighed up the pros & cons of taking the ipad baseband i.e. total loss of GPS and no way back etc. I'm not sure why it fails on you at the stage it does, it looks as though you are running Redsn0w on windows as you should or you wouldn't be able to jailbreak it at all. Just keep trying or find a friend with a Mac to build you a 3G custom firmware to include the ipad baseband and the right selection on activation, failing that you're left with searching the net or sites you trust for a pre made 3G custom 4.2.1, then put your iphone into pwned DFU using Redsn0w and shift/restore to it, might be an idea to restore to stock 4.2.1 beforehand.
