I'm am currently on .591 and 0.5 Liberty. Can someone comment if they flash .596 over Liberty? Brick or no brick?
I went from 0.5 LGB to .596 Deodexed and Rooted. I used the .zip method that you just flash over, I didn't even have to wipe. You can only do that is you have the .12p radio though, which I did.
Now to expand on your original question...I haven't gone to official GB yet over LIberty GB because I'm afraid it would be a step back from what Team Liberty has done for us. Either way, good luck to you.
