[Q] ODIN, Download Mode, JH7, Modems, Kernels... somebody school me

I've searched and read FAQs a lot already. I read the threads that XDA suggested before posting this.
I've been doing a lot of reading and I'm a little fuzzy. Want to root my gf's AT&T Captivate (JH7) and install Froyo for her but still a little unclear on exactly how everything fits together.
From what I've gathered so far I can use the update.zip method to install Clockwork Recovery and make a nandroid backup of her current configuration without even rooting it, right?
Then can I just flash whichever ROM I want? Will the ROM.zip update her to the correct modem/kernel at that time?
About using ODIN to restore - do I restore to the version she is on NOW or the version the phone originally shipped with, if different? And do I REALLY need to ODIN restore between ROMs or is a full wipe with CWM recovery enough?
Also read that CWM recovery doesn't work with Froyo at this time so can't do nandroid backups of Froyo ROMs?
Somebody catch me up... with my mt3g and mt4g I'm totally comfortable but this stuff is confusing me. I'm fairly comfortable with adb and already used it to sideload an app for her without rooting.
Thanks for your help guys.

I'm pretty new at this too so I'll try to answer what I can.
Before you try anything, just make sure you can get into recovery and download mode.
Recovery:
- Hold Vol Up + Vol Down + Power button.
- from adb type reboot recovery
- from Rom Manager, select the Reboot to Recovery option.
Download
- Hold Vol Up + Vol Down and insert the usb cable. This works for me. Getting Odin to detect it can be a bit tricky. I usually start Odin first, then connect phone.
- from adb type reboot download (I think)

Not sure to be honest. The way I do it is that I install Rom Manager from the market first. It will ask you for root though. I like this way better as you can download and install the appropriate update.zip from the app. Rooting is very very easy. You can use this tool:

To be safe, I only try ROMs that I find in the Captivate Development sub forum. Most of them can be installed with CWM. Place the *.zip in the root of your internal SD card, reboot into CWM and select the install .zip from card option. Don't freak out.
There is also a way to flash roms from Odin but I've never tried it to be honest.

I believe it will restore to Samsung's stock version (I897UCJF6). Check this thread: http://forum.xda-developers.com/showthread.php?t=731989
Remember that this is only for the Captivate. It is safer to do a full restore whenever you are trying a new rom. The only exception, I think, is when you are upgrading versions (say, Darky's 7.8 to 8.0)
Also read that CWM recovery doesn't work with Froyo at this time so can't do nandroid backups of Froyo ROMs?

I always install it using ROM manager and it works fine.
Now, from what I've been reading and doing this week, I learned that apart from the ROM, you can also flash the kernel and model separately, in case you have specific needs. For instance, I flashed glitterball's kernel to overclock the phone. Just remember that 2.1 Roms need 2.1 kernels and modems, the same applies for 2.2. Here is a list of modems: http://forum.xda-developers.com/showthread.php?t=835272
I'm currently trying out the TLJL3.
Remember that there are many ways to get to Rome. Also, use Titanium Backup to save your apps.
tl;dr:
1. Root.
2. Install CWM.
3. Verify that you can access recovery and download mode.
4. Download ROM (CWM .zip installable).
5. Read read read.

Hmm... Most of your answers can be found in
http://forum.xda-developers.com/showthread.php?t=884364
The ROM file would contain a kernel and a modem that will update her current kernel and modem. She can flash the kernel and modem of her choice after installing a custom ROM without breaking anything.
For Backing up use Titanium Backup, u need to ROOT your phone using directions in the earlier link provided.
When using custom ROMs it is always better to do a full wipe and flash to stock and master clear, i.e JF6 (using Odin one-click, or Odin with 3-button) or JH7 using the DG version.
You can follow
http://forum.xda-developers.com/showpost.php?p=10056254&postcount=36
Update.zip file once installed would load CWM from which you can install custom ROMs. Once you install custom ROMs, they are always rooted, and you needn't root again. It's a one time thing.
Hope this resolves everything..

Thanks for your replies, guys, I'm actually very familiar with rooting and flashing. To clarify, I already know HOW to install a custom ROM, that's not the issue. I'm more concerned about compatibility once I start installing custom stuff, and about UNROOTING if I need to. It sounds like if all I'm doing is installing a custom recovery and then a custom ROM, I don't really need to worry about it.
I always opt for manual method through recovery as opposed to Rom Manager.
I would use SuperOneClick for the stock ROM as I've used it before without issues. Most likely I would use the update.zip method to install clockwork recovery so I can make a nandroid backup of her completely unrooted stock setup before proceeding.
I can get into stock recovery just fine but haven't tried download mode yet.
And yes I would ONLY flash ROMs for the Captivate specifically, unless someone manages to complete a port for Sense.

Sounds like your good to go then.
... and Odin is just the cheap and easy method to return the phone back to stock.
So if you ever need to give it back and need it restored this is the easiest method to do it. But I would suggest formatting the internal SD Card to make sure there are no remnants of you playing around with the phone.

Agreed, will definitely do that.
I also heard that when using ODIN to restore to JF6 the OTA update to JH7 won't come back on its own?

lol yea.. but it doesn't matter unless you were wanting to keep it on "stock".
If your flashing or returning the phone your ok with keeping it on JF6.

If your phone came with JH7 and you have issues with Odin one-click, you might want to look at this guide, it has worked great for me and many others:
http://forum.xda-developers.com/showpost.php?p=10056254&postcount=36

How do I know what build number her phone is? I see references to build number 1010, but I don't know if this phone CAME WITH jh7 or if that was an update. I bought it used. If I try to restore to JF6 will that brick it??
EDIT - found it. She's a 1007. So if I used ODIN-3 to restore to JF6, how do I get back to JH7? Reading elsewhere it seems that a nandroid restore won't include the baseband?

Download the Mini Kies from here Download Center for SEG-I897ZKAATT.
Make sure the phone asks for USB on connection and select Kies mode when you plug into pc. Then open Mini Kies, it should recognize your phone and tell you an update is available. Follow the instructions from there.

Ok cool, thanks for your help! Already downloaded Kies from the Samsung website.
About to flash her phone but saw something somewhere about backing up some *.nv file to preserve her IMEI# and stuff? Can you link me to a guide on that? Can not for the life of me remember where I saw that.

Back to stock stuck on AT&T logo

I decided to root my phone and try some ROMS last night on my Captivate. Love it by the way except one problem that I can not seem to figure out.
Before I did any flash I used ROM Manager to take 2 backups of my stock ROM and also used Titanium to backup all user apps and data.
Everytime I try to go back to stock and the phone reboots after recovery mode I get the AT&T logo and it never goes anywhere.
How do I get back to stock?
THANK!

If you are trying to restore stock through nancroid backup that won't work. You need to use odin.
What build is your phone? You can find it under your battery, something between 1006-1012

It is 1012. I thought you could just restore from those backups to get back to stock.
I have never used odin before. How do I go about that?
Thanks!

I can not find a good download for Odin. Could somebody provide please?
Thanks!

With your build you need to be careful what odin you use
You wavy to follow this
http://forum.xda-developers.com/showpost.php?p=10056254&postcount=36
Clockwork does not restore kernel and modem. You are stuck at at&t screen because your system is ext 4 used on roms, and your nandroid is rfs. Long and short it won't work

So.... I am a bit confused now. Is there even a way to get back to stock at this point?

The link I posted
Your stock is jh7, odin One click is jf6. The procedure laid out in the link will get you back to jh7, although it takes a couple steps.
As long as you can get into recovery you can probably reflash any rom you have on your sd

Yikes thats a tall order to get back. Thought it would be more simple. So it is easy getting to a point to flash ROMS... Not so easy going back.

I'm also stuck in the same vicious cycle as we type.
I got 2 different stock rom backups and a cognition backup and can't get nothing to restore factory. I got premium ROM Manager. I can get into 2 different recovery screens. 1 from the Clockwork v2.5.1.3-voodoo lagfix and 1 using the update.zip on my root. Can't restore anything that gets me past the ATT logo.

What is your build number, under battery
Between 1006-1012

I don't see a 1006-1012 anything. Where exactly would it be listed under the battery ??? ON the battery ? my phone is 3 days old.
EDIT: oh I think its a 1010 ...I think I found it
Thanks for the help by the way.

Have you tried this
Phone off
Hold volume up and down and power
Let go when at&t comes up
Should be green recovery
Select install zip from sd
Choose zip
Select rom file that is saved on your sd, any you may of tried
Confirm
If your lucky maybe you can flash the rom

Uhh ??? Somehow from the recovery mode I just re-installed Cognition 3.04 back on my phone by browsing to the ROM.zip an installing it. I have to charge my phone for a few but I'll definitely come back and tell how I did it after a while. I think it was by browsing to cognitionv3.zip from 1 of the recovery menus insead of going to the update.zip. That beats the hell out of going through all the steps of going back to stock.
Thanks for the help.
EDIT:
Yeah somewhat like above post, only I had the Cognition (red) recovery menu and I went to install .zip and browsed to the cognitionv3.zip on my sd and installed it. *BLAM* back to Cognitionv3.04 I'll work with that till I got more time to mess with the other.

Yep I have tried that. Or at least I guess....
I go into the recovery screen but the problem is the only zip files I have are my custom ROMS. I did a complete backup with ROM Manager of the stock ROM before flashing however it did not create a zip file, it created a folder which contains everything that was backed up. I have tried to restore from that but when I do and the phone restarts it sticks on the AT&T white logo screen.

I am not saying restore stock, I am saying flash a rom. it may get you a working phone

Oh yeah I have done that just fine. I am using Cognition.
I am just trying to find my path back to stock.

Exactly, If you flashed a ROM on the phone the ROM is still there. Just use the recovery mode and choose "install a zip from sd" then go to "choose a zip from sd" then it will let you browse the sd for the .zip(rom) you just had. (not stock). It should be successful. Worked for me.
At least you will have a working phone and you can then look into going stock once you've read up a little more on it.
Just trying to help.
EDIT: oh, OK, I myself was in a panic and had just found that possible.

No problem. Thank you for the help!
I was thinking that when I did the backup with ROM Manager that it was creating a ROM version of the stock so I could flash back. Guess not though.

[Q]I think it may be bricked, but i cant tell over my vast wall of Noob-ness

As much as i absolutely hate making my first post a Oh no, Help me i'm a noob distress call, i have to ask it.
Tried to flash in a rom, went to wipe factory data. Factory wipe never started or succeeded just sat their idely, removed battery and immediately booted back into CWM wiped it again worked perfectly. Heres the bad part, i went to and flash in one of the 5 roms on my sd card and not one of the seems to be responding... i get an error message like so
E:Failure at line (9 or 10 depending on rom)
Copy-Dir PACKAGE:data DATA:
Installation aborted.
Tried to just reboot and it takes me back to CWM
i'm thinkin this is bricked? Any help would be appreciated (you can add in the noob insults as well if you wish lol)

your phone is not bricked.
make sure you have update.zip in your internal sdcard root dir. boot into recovery and install packages twice, you should then be in the right CWM mode.
then install the rom zip file from there.

Make sure everything is on the internal SD card, in fact its best to remove any external just in case of bad things
Also try using ODIN for the whipe and put all of your CWM and Roms on afterward

Thanks for the help guys, fortunately everything is there i can see the update.zip, three of my rooms and a bunch of other junk that was saved to the internal sd i have everything out of the phone and i am getting the same results when i try to reinstall the update.zip, and the same errors when i go to install the roms. Any ideas?

which rom are you on right now ? which rom are you going to install ?

you can use odin to flash back to stock, do a master clear. copy back your update.zip & andromeda rom file to your sd. then follow the above post to give another try.

[Q] Trying to flash Serendipity 6.3...

I've never flashed a rom before. I currently have stock froyo with the paragon kernel i flashed using the app sgs kernel flasher. I have clockwork mod rom manager, I created a backup of my current rom. So then I tried installing the serendipity rom from the sd card but i get an error message. I read on the sticky on how to flash a custom ROM you need to use ODIN and flash back to stock 2.1 then do a master wipe and re root it and stuff.
Their link to download ODIN is broken so I don't know how to get it. And is there really no other way to flash it besides doing a master wipe and using ODIN?

flash to stock and master clear is not needed. what IS needed are specifics on WHAT error message you get when trying to flash the rom you want

The error message is
"E: failed to verify whole-file signature"
"E: signature verification failed"
"Installation aborted"
Then it brings be to the blue menu so i just select reboot system now

bad download, re-download rom.

May be completely off, but it doesn't sound like you're actually in clockwork mod recovery, but rather stock recovery.
But here's the post with the one click odin with mirrors and I personally would suggest useing it since I generally like to stick to as clean a flash as I can:
http://forum.xda-developers.com/showthread.php?t=731989
Second, I don't know if you've ever seen MobileTechVids tutorial on how to flash custom roms, but I suggest you watch the full series first if you haven't already.
here: http://www.youtube.com/watch?v=MsafJ-9uRqk
I watch the series and try and stick as close to the tut as I can when I'm unsure (or the one provided by the Rom maker as they know what's best for their rom)...
One suggestion, when flashing Serendipity disconnect your phone from cable right before the actual flashing (gave me a glitch in which I couldn't mount storage via usb). Other than that, read read read. I feel it's all I do when it comes to this stuff, but proper research is indispensible.

Is the text on Recovery mode blue or green? If its blue, you're on stock recovery.

Ok I got the stock rom flashed back and rooted it using one click. Now for some reason I can't reboot into clockwork recovery mode. I flashed it successfully. So i click on reboot into recovery and nothing happens. I try clicking on install room from sd card and that doesnt work either

Power off, hold 3 buttons att screen will come on. Keep holding. Screen will go off. Keep holding. Screen comes on again let off the power button but keep the volumes held, this will boot you into stock recovery, since you said you flashed cwm already I'm assuming you mean with rom manager, so the update.zip should be on your sdcard, so just reinstall packages twice and you should boot into cwm.

On serendipities main "download" page they have instructions to install. In those instructions is a link to a file you can download. Place that file along with the serendipity 6.3.zip file in the root of your sd card. Use the " 3 button" technique or Rom managers "reboot to recovery" option to get into stock recovery. Hit "reinstall packages" once/possibly twice. That will put you into clockwork mod recovery. Select install zip from sd card, find the serendipity6.3.zip and click power to flash. Confirm. And after it does some stuff it will ask you to reboot. Upon reboot it will as if you want to enable lagfix. Hit plain "Yes". Watch it do its thing and viola...
You have the "dirty" way of how to flash serendipity... But first I please ask you to spend atleast a day reading this forum or others and understanding these instructions and the reasons behind them.

followed instructions off the website and still doesn't work
I was running 2.2 and have done a lot of reading a video watching (thanks Mobile Tech videos) and finally conjured the guts to flash serendipity.
I flashed stock using odin...that went great. Copied the update.zip to sd card. Installed zip twice in 2e recovery. Copied Serendipity.zip file to sd card. started in recovery mode, selected "install from sdcard" selected serendipity.zip file and it seemed to go through that process rather quickly. Then I selected reboot and then everything just started FCing all over the place. Can't even load the stock that I had on there. I don't know what to do. Help please. I can get it back into recovery mode. Tried doing the wipe data/factory reset. That did help either. Help please. I really want to try serendipity. Thanks again in advanced.

Did you run a restore using TiBu at all? Or was it just a straight flash from stock to Serendipity?
Plus, were you running a phone that came with 2.2 out of the box? Or did you upgrade to stock Froyo yourself?

I did run TB and I had originally flashed up to froyo (took me all night one night) and then went through the process I explained and hit the dead end. I finally was able to get odin to read the phone and flash back to stock. It was a learning process. I realized that I needed not only the Serendipity_6.3.zip file but ALSO the kitchen file to included with it. That wasn't in the directions I don't think. Finally got it all on there. I love it now. I appreciate everyone's help. Any word on a how-to for Bluedipity?

I currently am Running stock Rogers Firmware 2.3.3 and want to install a 4.0.4 firmware like Dark Knights 3. IS there anything else I need to do or can I just copy it to the root of the phone and install it with clockwork or is there something else I am missing. I go to recovery but it is the stock recovery, this is where I ma thinking I am missing something. The phone is also rooted. Can any one point me in the right direction. And yes I been looking on the forums and not seeing what I need.

If you can not enter CWM Recovery mode, you can not install ICS. You need to install a kernel such as Semaphore (installed with ODIN in box PDA) and you can install it and ICS with no problem.
Oh I forgot, when you go to install ICS, you must remove the MicroSD, but may occur Bootloop.

and backup the the efs folder first!!!

Sounds like clockworkmod is not properly installed.
Revert to stock using odin. Then install CF-root
http://forum.xda-developers.com/showthread.php?t=788108
This will root your stock rom and install clockworkmod.

Well I thought 'cause I'm on GB 2.3.3 it is OK.
Do I really need a new bootloader?
