I screwed up my phone (MT3G) by experimenting with files through TERMINAL. I'm running the latest Cyanogen 18.104.22.168. The phone works but it's acting kind of flaky. In order to RE-FLASH the SAME ROM over itself do I need to go all the way back to step 1 (install CUPCAKE, install recovery ROM etc etc) or can I simply WIPE and RE-FLASH the same 22.214.171.124 ROM over the existing messed up one? Will that "remake" all the file systems and wipe away all traces of my mess? I do have a Nandroid but it's no better than the current load.
