PLEASE HELP!!! I need to get back to stock and I need your help

I'm running a Froyo SS ROM from Chevy1 that's about all I know. I have RSD lite on my computer but have no idea what to do. I'm sorry for my stupidity but I NEED to get back to stock. My camera will not focus and I need to take my Droid to Verizon, so I obviously need to be back to stock. PLEASE PLEASE PLEASE HELP! Easiest explanation would be GREATLY appreciated. Thank You!

 

thank you so much for your quick response but honestly i dont think i know how to do this :-( I thought i understood that earlier from what i read elsewhere and when i tried it I was stuck on my rom with no service and it said i had no battery life. I am so sorry for the ignorance but can you please break it down further

 

Ok awesome thank you I think I understand all that lol. But one question i have is is there somewhere to get the stock sbf file. I ask because im almost positive I did this process earlier with the back up stock file i have on my comp and thats when I ran into being back on the Froyo ROM with the issues?

 

i only have one sbf file on my computer its SPRecovery_ESE81.sbf and its 6,197 kb, i have to be doing something wrong :-(

 

AMAZING! Thank you so much for your help! Keep an eye out, i might need it again lol. Thank you!
