[Q] Root, Roms, Lagfix, Froyo, OMG!

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?

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

[Q] Updating to 2.2.1

Hi guys,
I was just wondering, when the JPU (2.2.1) update comes, I would like to upgrade to it from scratch (remove voodoo, hard-reset the phone, etc).
As of now, I have stock 2.2 + voodoo. How do I completely remove voodoo and everything else, and update to 2.2.1 (not just disable voodoo)?
Does the upgrade through KIES remove voodoo?
All I want is a fresh new 2.2.1 phone, as stock.
Many thanks!

Any ideas?

create a disable-lagfix file/folder in /sdcard/Voodoo (/sdcard/Voodoo/disable-lagfix)
and it should disable Voodoo. alternatively you can disable it via recovery. it does the same thing. (creating a file).
when 2.2.1 is out(if ever), Kies should be able to upgrade without a hitch though i've never personally used it.
it's best to remove all lagfixes and tweaks and all that funny custom stuff prior to upgrading if you're aimming to be "clean".

Thanks, but what I was aiming for was a totally clean phone.
Meaning no disable-lagfix folder in sdcard. Just clean, stock phone.
Does the firmware update fix that or is there a way to achieve that?

Unless I'm mistaken, you first need to disable lagfix as described above. After this, you need to flash a new kernel which doesn't include voodoo or another lagfix. If you're flashing stock JPU or any other stock firmware, that will take care of your problem.

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...

It's because of the MODEM.. Use a different MODEM.. Try UGJL2

ok im a total noob to andriod. I can pretty much do anything with a computer.. SO is it the modem driv er on the flash that isnt playing well with the hardware? How does one update the modem settings?
Thanks

http://forum.xda-developers.com/showthread.php?t=835272
Good place to find some if the modems that are available. You want modems that are cwm updates.
Down load modem, move file to internal sd of phone
Boot into recovery
Install zip from sd
Choose zip
Select the modem file
I would suggest jk4

ok loaded jk4.... no change if not worse.... Where can i dl the original fl6 for cwm.... This really sucks.. im thinking i never should have flashed

ke5tny said:
ok the file is in a .bin.... how do i get it to load in recovery

?????
The downloads are all zips. You flash the entire zip. Did you pull the modern from the zip?
Get into recovery by long poss on power select recovery from extended power menu

Try putting your phone in airplane mode, then restoring service

well that didnt work either. the jk6 jacked up phone calls too. heres the current incarnation on ATT
firmware 2.2
baseband i897ucjj4
kernel 2.6.32.9
cognition 3.04
Market is dog slow... if it will dl at all... I cant use the original stock modem with the 2.2 upgrade can i.

jk4 not jj4. That is not the modem I said to try
Jk4

i did use jk4. that was the one that hosed everything up. i couldnt call out but could txt. i went to jj4 just to get it working again i cant find the original modem rom anywhere

Like the others said. When you download the modem it will be a zip file. Leave it as is and copy it to your phone. Boot into recovery, choose install zip from sd, choose zip file, navigate to where you saved it it and flash.
Be careful changing modems. I9000 modems dont play well with captivate kernels. Cog is pure captivate, so if you flash jk4 modem you should probably flash another kernel, ie, Firebird or speedmod.
I can assure you that if you are in a good service area, Cog 3.04 kernel/modem combo are great. I would personally flash back to stock and start fresh.
Sent from my SAMSUNG-SGH-I897 using XDA App

My suggestion is to try another rom or flag back to stock

That's what i think im going to have to do. I just got a full titanium backup done. Stupid question is there any way to flash back to original config with cwm or rom manager

Yes and no. you can flash the jh7ota package that can be found in the development section.
If you were going to do so you must didable lag fix first. I am not suggesting this though.
If you are going back to stock, I would use odin. Do you know what build phone you have, located under battery, something like 1008

sn r1xzc87098a no 1008 anywhere under battery

It will be anywhere from 1006 to 1012

ok gutting it and doing a reflash to 3.04... will see what happens.

odin
get odin 3 1 click downloader. put your phone in download mode. then click Start. that will reflash back to stock JF6 firmware. then once booted back up. put it back into usb debugging then hit master clear. that will completely wipe out sd and put stock firmware back on. its too easy. Now if you sent phone back in to samsung they will still know you hacked it. Because in october ATT sent a firmware update to JH7 2.1 update 1. to get it back on to be COMPLETE out of box. download samsung kies. and it will update it for you. poof. now there is an odin 3 one click for leaked captivate froyo. it looks like stock but has more options and its froyo. uses ji6 modem. works very good for me. just have to get super one click root 1.6.5 to root phone and enable app side loading.

How to revert to stock kernel

I have a Bell SGS, GT-I9000m. I'm considering installing hardcore kernel only, i.e. no custom ROM. If later I want to revert to the stock kernel, how would I do that?
Thanks for your help.
Sent from my GT-I9000M using XDA App

I'm not quite sure if it is possible with the stock-kernel but if you can make a full backup (like with CWM) you could restore it later. But why do you want to get back to stock-kernel?
If the backup-possibility does not work you have to find the stock-kernel for downloading and flash it via Odin or you have to flash the whole stock-ROM with Odin.

Thanks for your answer. I can't make a Nandroid backup while I'm on stock (because I can't install CWM recovery because I'm on 3e stock recovery, not 2e)
I'm not sure why I would want to go back to stock... Maybe something goes terribly wrong? I guess I just wanted to know if it was possible.
Last question: when you say I would have to find the stock kernel, is that just Google, or are there sites/repositories out there for this sort of thing?
Sent from my GT-I9000M using XDA App

I should add, the site/repo question is for kernels and stock ROMs...

Possible scenario
Alright, thanks for your help. I guess the one scenario that is bothering me is as follows:
1) Bell - FINALLY - releases their official Gingerbread update.
2) I've installed Hardcore kernel, which according to - http://forum.xda-developers.com/showthread.php?t=822756 - "works on all 2.2 and 2.2.1 ROMs".
3) Would I be able to install the Bell Gingerbread update with Hardcore kernel?
This is why I keep asking how I would revert from Hardcore because I obviously don't want to lock myself out of Bell updates forever.

It doesn't matter which kernel you are using when you are flashing with Odin. And Bell releases the updates later than Samsung, so you'd have the advantage of getting updates earlier with a 'free' firmware.

One solution to flash back the stock kernel is to extract the zImage (the kernel) from the stock rom and flash that with Odin or Heimdall.
But as far as I know having a custom kernel would not cause problems with installing a stock upgrade.

Done
I've installed Hardcore's kernel. Everything seems to be working fine, phone started up and picked up service.
I booted into recovery, enabled lagfix, turned on all of the recommended tweaks and then ran the Quadrant Standard. Things seem a bit faster, so I guess it's all good.
Next step, Darky's 10.1.
Thanks for your help, everyone.

One more question:
I did a Nandroid backup of everything (so data, dbdata, cache AND system). The restore option says "Be careful!". What's up with that? I mean, what's the caveat?
Thanks.

I've already made some NANDROID-backups, but never seen 'Be careful!'.
If the backup was succesful I wouldn't care about that.

*sigh*, I hate to keep adding questions on to this thread, but I must.
After installing the hardcore kernel and enabling tweaks and lagfix, I'm running into exactly this problem: http://forum.xda-developers.com/showthread.php?t=851970
My phone was extremely hot for a while, then I got a warning indicating that my internal phone storage was running low, etc.
Eventually, I found this file (/data/local/tsprsp) to be the culprit. I deleted it and rebooted and now my phone is fine. However, vibration just doesn't work at all!
Any ideas? Has anyone else run into this problem?

I was told that if you do a 'full' backup, in some cases restoration will fail with some error. But it depends on the version of the ROM you are using.
That is the reason why it is recommended to backup only data and if you want to restore, then first reflash your rom, then restore the data.

Thanks, zsori. That explains the "Be careful!".

you will have to flash back a stock rom via odin if anything wrong happen during the flashing of custom roms, although chances are low if you follow the instructions carefully.

Which Gingerbread?
So I'm continuing my quest to learn more about all of this custom ROM flashing stuff. And I wanted to get gingerbread on my phone... So I figured I'd just get an image from samfirmware.com and flash it. But then, I went here (because I was also interested in Darky's 10.1 so I was reading their guide): http://www.darkyrom.com/community/i...-darkyrom-gingerbread-jvh-noob-friendly.3080/
It says that flashing "Ficeto_JVH_I9000_Odin" will get me a stock Gingerbread. My question: what's the difference between flashing an image from samfirmware.com or flashing "Ficeto_JVH_I9000_Odin"? How do I know which to pick?
In all my browsing/reading, I realize that there are 3 "separate" parts: kernel, modem and then the "ROM". Ideally, I want to keep my modem as is... What does that correspond to in Odin? I've tried to find what "PIT", "PDA", "PHONE" and "CSC" represent in Odin, but I'm not sure I got it right. PIT = Kernel? PHONE = modem?
And finally, how do I know if a particular kernel is compatible with a particular ROM?
Sorry, I know there are lots of questions there. But please help clearing up a n00b's confusion. Thanks.

you got it wrong.
PIT is for mapping the partitioning of the phone. In most cases you should only use 512 pit file. and only use it when you want to wipe the phone.
the three parts is "pda" (which is the rom), "phone" (which is the modem), and "csc" (which is the carrier customization and apns)
the kernel is in the part of pda (the rom)
check the thread in xda of the kernel to see if its a gingerbread kernel or froyo kernel.
hope this clear things up

Yes, that helps. That's really good to know. So now, in Darky's guide to flashing Flash Ficeto_JVH_Odin, I see that only PIT and PDA are specified. This is reassuring, knowing that the modem and carrier stuff isn't touched.
Many thanks.

There are firmwares with three parts (Phone, PDA, CSC, including bootloader) and with only one part (PDA, no bootloader(?)). The one-part-FW is just an 'update', the one with three parts an 'upgrade'.
