Hey all,
So I'm am effing fed UP with Samsung. My Captivate is a hardware powerhouse, and with the stock Eclair firmware and all their bloatware, it's laggy, bogged down, and just not the device I wish it was. And with the talks that the Galaxy S phones are virtually unbrickable, I have decided to seriously consider ROOTing my phone and flashing the Cognition 3.02 ROM. I have watched a lot of videos, done my research, but I still have a few lingering questions for those of you out there who have recently flashed this ROM, preferably for those of you that this is the first or near-first ROM you've flashed. I know how the process works, but some specifics are bugging me and holding me back.
Ok, so I've listed some of my major questions below. Feel free to answer some or all of them if you've got the time, or DM me if that's easier. lf I think of any other Qs I have I'll post them in subsequent replies.
1. First and foremost, what process did you use to root and flash cognition on your Captivate? I've been looking at the MobileTechVideos three part tutorial on youtube which most people seem to recommend. Is this what you used? Was it as easy as simply following the instructions word-for-word? Did you run into any problems along the way?
2. I know to use Titanium Backup to backup my apps and stuff, but I've read a lot of places that I should only use it to restore those apps, and not to backup and restore user data like settings and contacts. How did you do it? My major concerns are about my contacts/phone book, which I have synced to my google account, but I also have syncs to my facebook and twitter accounts, and my phonebook is nicely linked and everything across all three. I'm afraid to forfeit this organization, so I just want to know that I'll be able to get everything back the way it was without too much trouble. I know you can export your contacts to your SD cards, and I could presumably import them from their after flashing, but I just want to be clear on how that all works.
3. Do you use your phone as a digital music player? I do, and I use iSyncr to sync it to my iTunes. If you do as well, did flashing screw any of this up? Playlists, etc? Will I need to re-sync or will it all be there once the phone scans my external SD (which wont be wiped since I'll remove it beforehand)?
4. In your first few days of use, what are the biggest improvements you see in the Cognition ROM as far as daily use is concerned over the stock firmware? Any problems you've come across? What's the selling points here, in layman's terms.
5. Do you have any regrets about flashing?
Thanks guys, and any other advice you think would be helpful that wouldn't come under any of the questions would also be GREATLY appreciated.
4. No problems for me. Phone is smoother and faster now.
5. Not at all.

1. manually rooting is overrated. most, if not all, custom roms automatically root your phone for you, so there really is no need for you to do it yourself. except the first time: root your phone using the one click since it's simple, grab rom manager from the market and use it to download an update.zip containing clockworkmod recovery for the captivate and leave that update.zip on your phone and never change it or delete it. it makes flashing new roms so much easier and there is really no need to ever remove or change it. boot into recovery, reinstall packages twice, install zip from sd card, and pick your rom. also, you will never need to use rom manager again unless you lose that update.zip.
2. I use titanium backup in batch mode (hit the menu softkey and hit batch). click backup all user apps and system data, but uncheck everything that is in red text, therefore backing up only things in green text (useful system settings, contacts, calendar, messages, etc) and white text (user installed apps). then run batch operation. install new rom, use batch to restore all missing apps and system data. to re-backup newer settings, app data, or updated apps, use backup all new apps and newer versions, and then either redo old backups or forced redo of all backups.
3. yes, but I just copy and paste my music files over instead of syncing them. also your internal sd is never wiped unless you use master clear on odin, which I have never done, nor do i ever wish to, because in my opinion there is no reason to. therefore both your playlists and your music would not be wiped whether you put them on the internal or external sd. (unless of course, you decide to use master clear)
4 & 5. I agree with faroid.
Be sure you have the correct odin set up and recognizing your phone on your pc. Eventually you will need to use it for one reason or another. The most common is the odin3 one click jf6 but some newer builds cannot be flashed to firmware older than jh2.
1. To root i use one click root/ unroot vary simple plug in and press root then install clockwork recovery from the market its free with clockwork recovery you can flash your cognition

5.no regrets, expect when i bricked my phone but the jig method fixed that

Did you use the full MobileTechVideos method when your phone got bricked? Or did you flash without reflashing to stock and wiping everything?

So how do I know which one I should use? Is it based on the ROM I flash, or my hardware (Captivate)?
Which odin stock firmware is based on the build (four digit number under battery such as 1006) and what version your phone came with when new, such as jf6 or jh7.

Do you by chance know which one I'd need off hand? I'm at work and don't feel like pulling my phone apart, but I can tell you that I bought my Captivate the day it came out, so presumably it came with the oldest firmware the Captivate ever came packaged with.
1. No need to root. That's an extra step you don't need. My method, get the update.zip for clockwork mod, just search the Dev section, no need to even install Rom Manager or anything. Take that update.zip and put it on the root of your internal SDcard (just the normal phone storage, not an external SD. Then using adb or button method reboot into recovery, choose reinstall packages. The phone reboots into stock recovery. Choose reinstall packages again and this time you get Clockwork. Wipe data, install zip from SD, choose zip file, pick Cog, install and done.
2. I use titanium for user apps only, ie, things I got from market. All my contacts are synced with google, so once I add my google info under accounts they are back. Sorry, i don't mess with facebook or twitter so i can't answer that. As far as settings, you just have to manually do that, ie, ringtones, wireless networks, etc.
3. Yes I do. And I also use iSyncr. No problems whatsoever. As long as you don't do a MasterClear. That option under Odin will wipe your internal SDcard also. The Wipe Data under Clockwork recovery just wipes out installed apps and settings but leaves your internal SD intact.
4. Honestly, it's just a much better experience overall. The phone is faster, smoother, and more responsive. Plus DG has taken the liberty of removing all the ATT crap and un-needed apps.
5. Not one.
My only advice would be to "be prepared". My sure you have button recovery available ahead of time. Check your Rev version of phone, ie, the date under the battery. It seems newer Revs require a different version of stock Odin One-click. Some people have had issues running the original One-click. If you have any doubts about your phones ability to go to download mode, in case you need to go back to stock, spend the $1 on building a USB Jig.
You will find that flashing is easy. Recovering from unexpected errors can be easy if you are prepared.

So do I not need to be rooted to use Ti-BU? I thought I saw that under the product description in the marketplace.
Also, under #1, when you say "Wipe Data" you are referring to an option in the Clockwork Recovery menu, not an Odin MasterClear, right? Will this wipe my internal SD?
If you got the phone on release you likely have a 1006 build with working 3 button recovery and can safely use the odin3 one click jf6.

TiBu needs root. I rooted using one click, then backed up user apps and data (used built in contact export to save contacts and smsbackup for texts).
Then I just ran the update.zip for CWR and flashed Cog - was my first flash too and pretty painless. TiBu returns your apps as if you never changed them.
Make sure you can access recovery and dl mode though.

Sorry, forgot you would want to backup before installing a new ROM. Yes, to use Tibu on your current ROM you will need root.
As for wipe data, yes it's a clockwork option. Like I said in #3 wipe data just removes user installed apps, and changes all settings to stock, but all data on your internal store will stay there, pics, music, etc.
Master Clear is the Odin option, which I never use by the way, that will completely delete everything on your internal SD, bye bye music, pics, etc.
This is all EXTREMELY helpful by the way.
Quick question about USB Jigs--is it easy to build one myself or should I splurge on the ~$15 one MobileTechVideos sells? There's seems pretty fancy, and I can't afford to be phoneless as I putz around trying to jimmy myself a jig.
I can't speak from experience but there's a thread here in QA that makes it seem easy. Just get 3 x 100kohm resistors, wire them in series, twist it to look like a horseshoe, there you go. If you have a radioshack or other electronics store near you it's worth a shot. Like I said, I think all 3 resistors cost may $1 total. You can also test it on your phone to make sure. Touch the jig to the 2 leads, if it goes into download mode instantly you did it right. Pull battery and reboot and all is well.

Yeah I saw that thread, I'll have to try my hand at it before I do this process. Better safe than sorry. Thanks.
Ok, so, the plan = build working jig and DL proper Odin just in case, one-click root, Ti-BU, move clockwork update.zip and cognition zips to my root folder, reboot in recovery, reinstall packages/flash clockwork, then wipe and flash cognition. This sound correct?
That sounds about right. Really the only thing different i do is on the root of my storage I create folders for ROMs. So I have a Cog folder with the rom in it. Once you have Clockwork installed and you are choosing to flash, it will let you navigate to different folders. That's just my preference because I don't like to have too many individual files on my SD. Minor thing, just thought I would mention it.

Haha, appreciate the advice; I like a little organization in my life as well.
Sounds like you've flashed a few different ROMs. Have you ever bricked your phone to the point where you needed a jig? Or has it always been smooth sailing?
I guess I'm just trying to figure out why one person's phone would brick and anothers wouldnt. It kind of makes me assume that if you brick your phone, you've done something wrong, and if you just do the process right, everything should go smoothly. But maybe that's naive of me.
ROM Manager says there's an update to Clockwork Mod. 3.0.0.x, is it safe to apply? Running CM7 rc2 right now.
Sent from my Nexus One using XDA App
Why wouldn't it be? And yes it's ok I've been using it since release with no problems.
Yeah it is safe to apply. I've been using it for quite a while.
I've tried to run with clockwork 3.x twice now, and both times my SD card (ext partition) got screwed up to the point that it couldn't mount. The only way I could recover was to reformat the entire card.
I don't know if it was clockwork 3.x, or user error, or just coincidence, but I've never had this problem at other times...
The web is full of similar examples, so until I know for sure, I refuse to use 3.x (I'm a clockwork fan, and use 2.5.1.4).
Sent from my Nexus One using XDA Premium App
Ive had some annoying issues with version 3 also. Never a problem in 2.x
I use RA when I have issues. 3 seems to integrate the GUI but causes problems while actually in recovery mode... I was wondering if I was the only one. I'm definitely a Clockwork fan.
Clockworkmod 3 has problems with sd card, in particular if you are using DT apps2sd.
In my case, it didn't restore to the sd card properly.
I reverted to clockwork 2.5.1.1 and was able to replay my backup. For now, I am staying with 2.5.
yeah cwm 3 has given me nothing but grief. refuses to flash roms, wiping sd card completely, left me in a sticky situation the other day as i had nothing to read my sd card, and have been stuck in the same situation again right now, switching to RA recovery from now on. nothing but grief.
however, glad to see im not just losing my mind and im not the only one experiencing things like this
general consensus is that it is safe some people though like me had issues with it. It wouldnt restore my backups correctly and would freeze in the process. Bc of this i stuck with version 2.5x
I had the same issue with CWM3 totally screwing up my ext3 partition, to top it all off I couldn't access any of my previous backups and wound up having to totally format the SD card complete, repartition and start from scratch with a backup on my PC that was several months old. VERY ANNOYING! Needless to say i now use AmonRA with ZERO issues and I will be pretty hard pressed to go back after that little fiasco...

I couldn't get CWM 3 to complete a backup...pretty essential, so I went back to 2. May try the update and see if it works.
Long ago I had issues where my backup would freeze. Temp fix was to restore each individual section which allowed me to at least restore that backup.
I have recently flashed the JVS firmware from samsung firmware, and then followed that up with this CF-Root-XX_OXA_JVS-v4.1-CWM3RFS, flashing via the PDA section in ODIN. My phone has been working perfectly for a few days, no problems at all, until right now when I've gone to restart the phone.. I was having troubles with the market, and I turned my phone off mid-download of an app.. I'm pretty sure it was mid-download and not mid-installation of it..
However, when I turn my phone back on, it'll show the Galaxy S I9000 screen, then go to the next screen with the glowing S, however after that, it just gives a quick, short vibration, and seems to turn off, then do it all over again..
What does this mean? Is there a way I can get out of it without re-flashing the entire firmware? I am still able to get into download mode, but I don't want to lose messages that I have saved on my phone..
Any help is greatly appreciated..
Denno
Ok, so I let the phone go for a while (around 10 minutes), of the screens cycling through as mentioned above, but now it seems to have actually found a way into the phone, and has now loaded up properly.. However, I'm still interested in what the problem could be on the phone??
are u using new market app?
its happened to me once and i reflashed whole firmware starting from 2.1 to 2.3.5 lol just to avoid sh*t like that
When I had 2.2 on there, I had the new market app, however after flashing 2.3.5, it had the old market, so I was downloading apps from the old market at the time..
What do you mean you re-flashed whole firmware from 2.1?
Anyone else have any ideas?
Try to wipe factory reset and wipe cache or try to flash rom again
Wysłano z GT-I9000 z użyciem Tapatalk
Could be a corruption in the bootloader, if it happens again i would reflash. Otherwise just leave it i guess, maybe it was a one off
It happens pretty much all the time now.. I have reflashed the firmware a couple of times.. And it still seems to happen. What would wiping the cache remove? Will I lose any settings or anything that I have on the phone? I have been restoring backups made using titanium, however just apps and data, not system settings..
If it's the bootloader, is there any way of fixing that?
Thanks
Ah that could be the problem. Sometimes when you restore backup they can conflict and thus cause issues like this...
Try only return the data, that works for me. Get app list from the market and after a backup move to external sd. Format internal sd card. Then do an Odin flash with repartition checked. This is designed to get you back to factory state, so you will loose everything. Make sure your backups are not on your internal sd when you format. Also before you flash i think its a good idea to put a copy of your nandroid backup into the internal sd. Or just use a nandroid backup from when you phone was working fine.
Deleting cache does not delete your settings usually, however when deleting dalvick cache it can take up to 30 mins (max i think) to start you phone, but usually its 5/10 mins.
Yes bootloader can be fixed just find a flashable bootloader with a rom or the directions given. Use search for this
Ok thanks for the tips Talon.. Firstly, this nandroid backup that I keep hearing about.. What exactly is that? Is that the backup that I do through Clockwork Mod Recovery? I'm also unsure how to return just the data to apps? I had a look at Titanium Backup, and the only data recovery option is for system data.. Everything else I think I can handle..
Thanks
Yes nandroid backup is the backup through CWM. You should always do one BEFORE you flash anything on your phone. And keep them in a safe place and leave one in your internal sd card.
You should use titanium backup to backup up a single app at a time, not batch. This way you'll have more files and can choose which apps you want to return, and if you only want to return the data. (I have always done it this way, so i dont know if you can pick the apps you want to return if you do backup via batch.). Use the other app i suggested to keep the market links, so you download the app from market first then you install the data once its there.
I suggest you don't return any apps at first see how it goes, then add either a couple or one at a time, again only the app data. (Once you backuo the app individually, flash then, TB, backup/restore press on the app, restore, then pick data only...) If you go from froyo to GB i think you cant do it)
Thank you very much for your reply Talon. I am currently on JVS, and plan to re-flash this exact same firmware, which is the stock firmware, nothing custom..
As for what you've written, it's going to take me a few reads before I can get my head around it, but I just wanted to say thankyou for a quick and detailed reply. I think I might just bite the bullet and figure out which apps I actually use, and just work with them for now..
I'll post back soon hopefully with results.
After getting very frustrated with the phone, I've finally re-flashed back to a seemingly stock situation. Phone is running great, and all problems seem to be gone. Slowly re-downloading apps from the market as I feel that I need them, so I hopefully won't get any interference from the old backups I had..
One more question, how do you make your backups? If you say you don't use the batch mode in Titanium? I can't see any other way that's as easy..
Thanks for your help Talon.
As i said before, backup/restore click on the app you want to back up, and click backup. When you want to restore it, back to the menu, click on the app, click restore, then pick data only longer but safer
Change the location of TB to your exsd if you haven't already, then go to setting find, and it will make it default location
Ahk.. Sounds very time consuming.. lol..
Phone is running like a champ now . Thanks
I have searched for this, and have seen some answers, but none of them specific to the Captivate.
Here's my scenario: My wife's phone has some dead pixels on the camera sensor, so I'm planning to take it in for warranty. I'm going to be flashing back to stock and all the other prep steps, but she really likes the setup exactly as it is now.
I know that I can use Titanium Backup to make a backup of everything and bring it back once she has the new phone (that's my backup plan if Nandroid isn't an option). However, having used a nandroid backup on my own phone when switching roms, I know how easy it is to get everything back in place really fast.
My question is this - can I simply make a nandroid backup of her setup now (Firefly 3.0, default FF3 kernel) and then restore it to her new phone (after flashing FF3.0, of course)? Or is this going to be more heartache than it's worth and I should just prepare to do a TiBu restore later?
As background, I've also seen that people mention the Nandroid doesn't worry about modem/kernel/bootloaders, and I know I can do partial restores of items in Nandroid (system only, apps only, etc).
Any information / personal experience anyone can offer would be appreicated.
Should work, don't see why it wouldn't, if it doesn't then the worst case scenario she will have to set her stuff up after a tibu restore.
No chance of bricking = no harm in trying.

That makes sense. I'll give it a whirl, and I'll post the results back so that there's some reference for anyone trying it in the future.
