As I just found out about rooting and such, I found the Reborn Rom and really wanted to install it on my Optimus S. I rooted my phone with GingerSnap, and its supposed to be rooted fine. I need to update the baseband, but in order to do that it says you need to make a nandroid and custom recovery, but I can't seem to figure this step out. Because whenever I try and type the code into the Adb shell, it says that the permission isn't granted or not allowed, and it won't let me flash it. I was using the the latest Xionia CMA. Can someone please help me because I've searched everywhere to figure this out, and I don't want to brick my phone!
