Sorry if this is the wrong section but i need some help, let me start off by saying im not new to computers but i am new to this. Yesterday i went from stock 2.1, used RSD to goto 2.0.1 rooted, then went back to 2.1, now im using OTA 2.2 stock. Ok what i want to do know is run your bugless beast v0.4 with the smoked glass theme (with no tabs). how should i go about doing so? now some of my questions are: 1. whats a rom, is the rom v0.4 or is it smoked glass? 2. whats a kernel? what do they do and any suggestions on one to run 3. whats nandroid? and what sb recovery? what do they do, where can i get them, do i need them for what i want to do? i did everything yesterday without them. Now heres my deal, i understand how to get v0.4 to work on my phone i go into recovery mode, wipe, then install zip, this worked for the most part, EXCEPT on any bugless beast froyo OS i tried to use, i wipe, then goto instal zip, it starts to load up the i get the error code "E: signature verification failed" then installation is aborted, so i have to reboot my previous OS. whats going wrong and how can i fix it, also once i get this to work how do i install the theme? i really need some help lol thanks.
