Ok, well I'm guessing I don't have root. Here's what I did:
Complete wipe of phone (fastboot or whatever back to stock). Installed the dual boot stuff, with a stock ICS rom in the default (safe) position. Rooted the rom, then created a slot for the JB rom. Installed JB, started the JB kernel and booted. Then I tried to gain root access and it didn't work. I'm still rooted on the ICS side, but can't get root on the JB rom. Did I miss something, can someone give me a detailed explanation of how to dual boot ICS and JB and keep the root in the JB side?
Thanks in advance, I can't find any instructions on how to do this anywhere..
