Hey guys I have a rooted captivate running froyo. I want to try the Cognition v2.3b3 rom with lagfix, but I no idea where to start. Do I need to flash back to stock or can I just load the rom? Also I was wondering about overclocking, can I do that with this rom? Any help is appreciated. I am new to android, came from a unlocked iPhone this is way better! Thanks guys

you should be able to flash over but it is considered good practice to start from stock, also i think you need ji6 froyo before jj4 froyo which cog2.3b* are based on, so the accepted proper procedure is masterclear and flash jf6 from the one click installer get android id with android id changer, flash ji6, also a one click installer, and then flash cognition. all with odin. you can clockwork recovery flash cognition but it is another proceedure to root ji6. after cognition is installed reinstall android id changer and load the id from the stock rom.
i usually flash over without lashing to stock ect unless the flash over has issues. and overclocking is handled in the kernel you need to flash http://forum.xda-developers.com/showthread.php?t=828052
with odin, no .pit file needed just drop file in the pda slot and flash in download mode. overclocking is enabled by default so you need set cpu to manage it.
there is a link to an app to manage under volting, my settings are -50mv low and -75 high. it also handles the scheduler, i use cfq. anticipatory seems to work eqaully well. some suggest deadline and it may be better real world but i dont see it in benchmarks. and real world is too subject to placebo effect and coincidence.
this kernel also has a universal lag fix handled in clockworkmod recovery which replaces the stock recovery. best setting for that is no rfs jfs overkill but in the advanced settings disable bind to dbdata. it's fast! 17.299 mflops in linpack, and it's the first time that i have had a lagfix improve a linack score(at least it appears to)
Here is the steps that got me from ji6 2.2 to cog.
First if you don't already get titanium back up and back up all of your apps you don't want to loose and copy the file to your computer and remove external SD card if you have one.
Then i used the 2.1 version of odin one click to go back to 2.1 after that do a master clear then root your phone and down load rom manager. Using rom manager flash the clockwork recovory mod.
Next download cognition 2.3b3 then go back to rom manager and select install rom from sd card and find your cog rom you just down loaded and it will do the rest
Once cog is on your phone you can put you titanium backup file back on your phone and redown load titanium backup and restore all of your apps.

@ Dani897 I do have ji6 version of froyo. So I do need to flash back to stock 2.1 or can I flash cog with the version of froyo that I am running now? Sorry for the confusion here. I would like to keep running froyo if I can. Thanks guys
Check out the Cog wiki.

If you have clockwork installed, you can install over any rom. I would clear data to be on the safe side, though.
no you cant. it will only work if he has 2e recovery kernel. if it was the ji6 leak then it is running 3e recovery and no matter how hard you try, it wont boot into clockwork.
answer:
use the ODIN version of cognition. doesnt matter what rom you are on...
Ok so I am trying to flash cog via oden. I downloaded the file and am looking at the how to on the wiki but, in the wiki it says that all the files will be in the download Odin.exe PIT.pit PDA.tar PHONE.tar CSC.tar. The only files that I am seeing are the pda file the odin.exe and the pit file none of the other ones. Is this normal?
Yes. That's what is supposed to be there. That's all you need for that particular rom

Cool thanks a lot for your help. Just to make sure before I do this. I did a back up using tibu, Im going to pull the sim, open odin, and flash. Is it really that easy or am I missing something? Thanks guys I really appreciate it.
Ok just flashed and that went well, but it wont let me open any apps. For example when I try to open up tibu it tells me I have to force close. I also dont have 3g

i dont know if there that is a common issue, but im sure you will need to reflash. you may want to flash to stock.
it's a multi step procedure and annoying but it is usually safer , i guess i got lucky.
i dont know for sure if you need to flash ji6 before cog 2.3b, design gears may have fixed that, i didn't read the details of why it was needed.
i would;
(optional)master clear, remove sim and sdcard. you will loose everything including titanium backups and posibly nand backups. master clear is done with the phone booted normally.
flash jf6
flash cognition 2.2 by meathod of your choice (so you have root and clockwork recovery)
flash cog 2.3b3 in clockwork mod recovery.

I don't know iflosing every thing is worth it for me, I really do want to flash this rom and try it out, but right now seems risky, I flashed back to froyo that I was running before. I thibk I'm going to do some more rese
