Some basic questions here, i just rooted over the weekend so i'm very new to it. I'm running bugless beast 0.4 with Froyo 2.2 and i'm running the red glass theme.. my questions are mainly about switching out roms/themes. Ok so i just did a nandroid backup..and i want to intall a new theme..can i just go ahead and install it over the theme i have now? and if i want to go back to that theme with all my data, do i just do the backup? also do i have to clear the cache everytime? stupid question but when i did that the first time i lost everything i had O_O Now with roms, how does that work? If i want to change out roms i mean. theres a theme i want that doesnt work with the current rom i have. Just wanted to ask before i do anything on my own and cause problems.
