So I am picking up my Captivate tomorrow morning, and I want to flash it out of the box. I have been doing a lot of reading, but I have no confidence in what I am doing. Now I know there is a simple one-click unroot, and I'm going to choose that bc its seems the easiest to root and unroot. After rooting, I want to load the Cognition ROM. Here is my first question, do I load OCLF first, and then flash the ROM or after, or does it even matter bc Cognition has Voodoo lag fix on it? Can I load both or would it not make a difference? I also read that you should always run a backup before flashing a MOD. What does backup really do? Is it similar to like a System Restore on Windows? What do you suggest is the better way to backup your data before flashing a ROM, NanDroid/Clockwork or Titanium? Also, which ROM do I flash? I do want froyo, so do I just flash the latest version (Cognition v2.4.1) or for some reason it seems a lot of people stick to Cognition v2.2. beta 9, is there a particular reason? Whatever I flash to, I want to stick with until Gingerbread releases. Now after flashing a ROM, I would like to install Setiron kernel (actually I dont care for the kernel or care for what it does save the BLN- BackLight Notification function) via SetiroN i9000 SuperOptimized ReOriented v1.2.6/1.3.5 ULF OC/UV BFQ 343Mb BLN ([KERNEL] SetiroN i9000 SuperOptimized ReOriented v1.2.6/1.3.5 ULF OC/UV BFQ 343Mb BLN - xda-developers) but there is a lot of information there that I dont understand. I am very new to this, and was wondering if someone could give me some insight on how to do this. I read CapFAQ and cldnt find information on there. Also, I wanted to add the Darkness theme ([THEME] Darknessv2.3 :: Black Dialer & Buttons! :: MM & CWM [2010.11.12] - xda-developers) but it has two options (1) JK2/JJ4 Cog Hybrid CWM Flash v2.3 -20101112 and (2) JI6 CWM Flash v2.3 -20101112-. Now I know JI6 and JK2 refer to updates but what do I choose? What is the difference? Thanks to anyone who helps me. Also, I apologize in advance if I am inconveniencing somebody, I know a lot of people prefer that people research on their own, and I promise I have been googling this stuff for the past week. It is a lot of information tho, and can be confusing.
