I just got my replacement phone from tmobile and thought I would just nandroid back up the old phone and restoring it on the new but it doesn't seem to work. Am I doing something wrong?
you still have to root the new phone enough to put the HardSPL on it then you can fastboot flash everything to it, the stock SPL does not support fastboot
I started the exact same thread here and solved the problem. There are detail instructions as to how to get this to work. You just need to pay attention to filenames and folder names but its very easy otherwise.
