I recently rooted my galaxy nexus so that I can get the Jelly bean JRO030 update for verizon. I would like to make some customizations since it is now rooted. I tried to do this on my own using rom toolbox pro and i bricked my phone and had to go back to stock and reroot and reupdate (which was a headache). I would like to try this again but with a little help. Do all custom themes work for all roms? If not, which ones will work for this new JRO030 update? Where do I find these and how do I install it without messing up my phone again. THanks in advance.
