I am currently on the Watermark'd theme and would like to try other themes and ROM's. However, I read that some themes/ROM's require a clean install if another theme/ROM is already installed. I would like some clarification regarding what precautions to take before attempting to switch to different themes/ROM's. I heard that I should wipe data & cache, restore to stock rooted .596, then apply the theme or ROM. Is this the correct method? Or would I have to SBF, follow the steps to rooted .596, then apply? Also, when wiping data and cache and restoring, can I do both (in that order) while still in Clockwork Recovery?
