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.
http://cognition.theidiotshideout.net/mw/index.php?title=Main_Page#Installation
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.

Cool gonna do it now. Will post results
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 research and see what I can find. Thanks for all your help guys
i have read some good things about Axura RC2.2 CE. so im very interested in flashing it. im currently running cog 2.1.7 is there any reason i couldnt just use rom manager and flash it right now. or should i flash back to odin stock and then re root grab rom manger again and then flash Axura RC2.2 CE? and in the instructions it said to backup with titan just data and apps but not system data, why is that?

The reason why people recommend ODIN first before flashing new ROMs is because lagfixes and other stuff can cause problems for certain users. Usually you can flash directly from another ROM no problem, but like I said, ODIN and most of your problems will disappear.
As for not backing up the system data, you can backup your system data. Just don't restore it as this can cause a lot of problems. There are framework differences, etc. between ROMs especially 2.1 and 2.2 ROMs. Restoring system data will cause FC city in most ROMs.
i just tried flashing and my phone got stuck in some mode where it kept saying stuff about partitioning and my sd wasnt found.. so lame
i backed up my stuff on titan and saved it to my computer ill try again after i root. hmm weird now its not running the zip file..
Did you Odin 1 Click back to stock first?
Never a good idea to flash over the top of another custom ROM as the guy above me stated already.
You always want that "clean slate" to start with to avoid issues like this. Then you can safely restore your applications and application data - but people have problems restoring system data - so I never do.
Odin 1-click back to stock and try again - it should work fine.
i just ended up odin one clicking it to froyo. which im loving right now so ill keep it like this for a bit. when i had reset my phone to stock i tried axura again but it wasnt running the zip for some reason..after im donewith 2.2 ill go to stock and try axura one more time.

Hmmm..
Easy method to ensure success:
Odin 1-Click back to OTA JH7 2.1 ECLAIR Stock (not 2.2 Froyo)
Root using CLShortfuse's Root application.
Then update to Auxura as normal and it should work fine.

I Have A HTC Hero But I'm Pretty Sure It's The Same....
I'm Not Sure I'm Understanding Your Question, But I Think You Want To Get Back To Your Stock ROM & Flash A New ROM Correct?
If That's It?
You Can, But You Don't Have To Convert Back In Order To Flash Another Rom.... Just "Wipe"
System/Cache/Dalvik Cache,
& Install The New Rom!
You Can Always Restore Back To Your Stock Backup!!

No you can not revert bacj to your stock 2.1 from 2.2 using clockwork with a captivate
Can you explain how to wipe system /cache/dalvix cache or post link i googled it but found nothing with step by step instructions. I would like to try this before odin. Also why does it let you create a back up of 2.1 rom if you cant revert back there from 2.2 then whats the point of backing up 2.1 in the first place. Just thought you could do that instead of odin after reading a post which I was going to post the link to here but wont let me cause Im too new.

I do not recommend flashing phoenix over cognition without a flash to stock, but if you want to try, you can.
Cognition uses voodoo. First thing you should do is disable it.
Find voodoo file in your internal sd. Create a folder in side voodoo folder named disable-lagfix. Reboot phone.
Ok its disabled, but If Odin is the best way to go maybe I should try it but just been reading about higher risk of bricking phone using odin. Just really want to try different rom because cognition it smooth as butter but battery life is killing me compared to stock and yes I tried the charging battery to 100 then unplugging shutting down charging to 100, reboot, shut down then to 100 again no help. Anyways if I use Odin does voodoo have to be disabled also.
Pull your battery. Obviously power off first. Under battery is a build number, mine is 1008. Tell me yours
mine is 1010
Odin may be difficult to use. You may want to research your build more. Anything over 1008 is where odin is an issue
What is your base
Settings, about phone, bottom
Damn i didnt want to hear that,Says baseband version I897UCJI6 is that it.
Yes that is it.
Being on build 1010 I an not comfortable with telling you how to proceed. You need advise from someone who flashes with that build. It behaves differently with odin. I am sorry. Search build 1010
Ok thanks for your help, Ill look around
If you've never flashed with Odin one-click before, try this instead to avoid any risk of bricking (very likely on some build 1008-1010 phones that don't run JF6 stock):

Me And several people I suggested it to. But now I have a batch 1009 Captivate (traded in mine because of random shutdown issue).
saved my cappy once
I guess I'm confused...is odin really necessary at all for him? If he disables voodoo lagfix, and clears dalvik cache, he should be able to flash over the top...correct?
I flashed cognition 3.02 direct to andromeda 2.0 via cwr and did not clear dalvik or disable lagfix (since cog and andromeda both enable voodoo)...no problems for me.
Maybe it's different/more complicated flashing over the top to the ROM he wants to go to though...

Hello,
I have Galaxy S 2.2.1 rooted (CF-root) with woring CWM, a Nandroid backup, and Onecosmics ICS goodys locked and loaded on my internal SD card. But still I can't find the b...courage to do a full wipe and flash ICS as if something goes wrong I will be without a descent smartphone for about 2-3 months.
My question is if I can flash straight from 2.2.1 or I should go through CM7 first.
One flash is simpler than 2 in my head..
I reckon that as the days go by I will do it and I want to make sure I do it the right way.
Thank you in advance.
Hi,
I, personally, went through a CM7 flash before going to OneCosmic's ICS, leaving Froyo. It took me about 10 minutes to do it, and in doing it this way, you stay close to OneCosmic's installation instructions.
1. Flash CM7
2. Reboot and test your phone (without installing apps & widgets)
3. Flash OneCosmic's ICS
Hope it might help!

I would recommend flashing JVU (using Odin) before cm7 as it contains the latest bootloaders, just to make sure everything works as it should
Sent from my sgs
thanks!!!!
Yeah,
First I think you should install JVS with CF-Root and recovery.
Just register to samfirmware, where you can easily download the required files, also you'll find some tutorial. For CF-root, just google it, and you'll also find some tutorials, than just put the zip in your internal sd, and install it from recovery. Don't forget to remove your microSD before flashing, cause it can be damaged after.
If you did something wrong, you can still go back to stock JVS ( happened to me ) and start it over.

Dont worry, you can always Odin back to 2.x
Download mode through 3-button-combo > Odin (re-partition checked!)
Thank you for your insights, I will probably go to CM7 and then to ICS and if i get any issues I ll go back to 2.2.1 and then start from JVU.
I will let you know, soon I hope..
Going via CM7 should be the safest way. CM ROMS are the easiest and quickest ROMS to flash imo and you shouldn't have any problem. Once you do that without any problems, flashing ICS should be as easy.
Gluck!
So I tried to get CM7 over 2.2.1 with no success so I took the long road and upgraded to stock 2.3.4 via Odin, then flashed rooted CF root kernet, then upgraded to CM7 and finally (and after a lot of sweating) I got to Onecosmic's ICS which is great and really a major upgrade!
I think I have some donating to do........

Sent from my GT-I9000 using Tapatalk
Hi, quick question. Can anyone confirm if the official 2.3.5 update through Kies Mini includes flashing gingerbread bootloaders? Until recently I've only run KB1 roms, but I now have CM7.1.
Briefly, I used Odin3 1-click to go to UCJF6, did a master clear, then used Kies Mini to go from 2.1 to 2.2 then 2.3 as per instructions. After that I went right to CM7.1 with no issues other than the expected bootloop after flashing the speedmod kernel which was resolved by flashing the rom.
BTW, I'm finding CM7.1 as solid and stable as I would ever need. (The main reason I stuck with KB1 releases for so long.) Many thanks to all the developers, maintainers, etc. for keeping the captivate alive.
Yeah to even run a STOCK GB rom you are required GB BL's... It won't boot without it...
And Why do you flash the speedmod on 2.1?! that was changed a long time ago...
Thanks for the reply. I went back to 2.1 because I hadn't come across Odin3 for 2.2. I was actually on 2.3 when I flashed the speedmod (according to what I read it is now safe to go this route.)
Ohh yahh, but you can One click to JF6, then flash the BL only ODIN, then it will reboot to recovery, apply update.zip, and flash from there!
OK, thanks. I'll remember that for future reference. Just wanted to confirm where I was at because apparently there is no straightforward way even through adb of checking your current bootloaders.
