So, I rooted and am currently running the CM 9/15 nightly and the #14 uncapped. I know that when installing a new rom that one should wipe the cache and dalvik cache..not data. I use Rom Manager and the only option is to clear data and cache. How can this be done properly utilizing this app? I have done backups separately and installed nightlies without doing a wipe. Will this screw things up? Everything seems to be ok and my phone runs great. Also, when I also choose the backup option with the wipe option it runs but states that there is not enough internal memory to perform this and stops. Currently I have 83.67mb free. How much do I need?
