OK, I've been reading here for 6 days all manner of Captivate unbricking. Here is my story...
I picked up a Captivate on the Rogers network. I connected it to my email server (Exchange 2010) with no problems, poked around, noticed the lag, noticed the SMS time issue, then promptly rooted, installed clockwork, and then threw cognition 2.2 beta 9.1.3. Quite frankly I was shocked at how much faster it was.
Anyways, after a day of poking around, I could not get my email to my exchange server running (tried the email.pak floating about), so I actually decided I was going to go back to the backup I made of my phone using clockwork before I installed cognition. When I restored my backup, I thought I had bricked my phone.
I let it rest for a day, then came back here, and found one of the 3-4 different variations of the 4 button download mode combo that permitted me to do the 1 click restore. This restored me to the AT&T version of 2.1. It worked, but was less than desirable.
I decided that at that point I really wanted to go back to stock, so I downloaded the stock backup on the Rogers Captivate wiki page, and did the restore using clockwork. The phone has not been the same since.
When i turn it on, I get an at&t splash screen, then in about 20 seconds I get the at&t "jingle", but the splash screen stays on. I can't seem to find any key combination that will permit me to get back into download mode so I can restore using the One Click that worked for me the first time. I have tried:
1. 3 button salute with USB in first, battery out initially.
2. 3 button salute with USB plugged in *as* I was inserting the battery.
3. Power and volume down (both with and without USB, and with battery being plugged in after USB and "during" insertion of battery)
4.Power and volume up with same combo's as #3.
5. Just volume up and volume down with same combo's as #3.
In all cases Odin was running before USB connected, running as administrator. I'm running 64bit windows, but I'm sure I have the correct drivers because I did this the first time with Odin and download mode and I haven't added or changed anything. But just for arguements sake I did uninstall, and then install the drivers again.
Any combination of power and volume buttons just gives me a battery charging logo. Occasionally when holding up until the second black screen I will get a quick indication that the computer might see something, but it dissappears withing a handful of seconds showing it promptly removed.
I'm downloading the Android SDK in the hopes that when I get the normal at&t splash screen after the "jingle" that something might actually be running in the background and maybe I can adb reboot download it but I'm not holding my breath.
Anyone seen this that has managed to get out of it? I'm starting to think the "unbrickable captivate" can be bricked. Assuming it is bricked, short of taking it back, is there anyone on the internet that can jtag these and in some fashion bring back to life?
Cheers,
Tim

and download mode is easy.
1. start odin3 and have data cable plugged into the computer
2. insert proper files if needed
3. hold volume up and volume down for 2 sec (no power button needed) then insert usb cable, continue to hold volumes till either the download mode screen pops up or odin3 sees the phone(if you bork the phone bad enough you can corrupt the download mode image, i did it with the not to successfull manhatten project kernel) but despite the screen being black it very well may be in download mode.
4. start flash
5. if it doesn't work send it to me ill find a use for it
alternatively if the phone can go passed the splash screens and boots fully you can adb reboot download. just get the development kit and drivers on your pc.

just to be clear, you are holding volume up as well as volume down starting with the phone being powered down and continue to hold them after you plug in usb untill something shows on the screen?
if your phone is not seeing the volumes buttons you are one of the very unlucky few that had a problem at the most inopportune moment.
there is also a way where you hold all three buttons till the phone reboots twice, or something. let me try it and ill give more specifics.

Pull the battery, open odin, plug usb into computer, hold vol up and down, plug usb into phone still holding vol buttons, drop in battery still holding vol buttons, when dl screen pops up and yellow com port lights up in odin release volume buttons. Do not touch power button at any time
Swyped...and sorry I don't proofread
Have you tried rebooting into recovery mode instead of download mode? Stock recovery is adb-ready and you should be able to adb reboot download. Its a long shot if you're having problems using button combo to get to d/l mode, but it's probably still worth a shot at this point.
If you were able to use 3 button combos before all this happened, and did NOT have to install the 3 button combo fix, its strange you don't have access to it now... Could restoring a Rogers Cappy to AT&T stock be the problem?

Yes, that's exactly correct. I do this:
1. everything pulled (battery, USB, sim, sd)
2. Open Oden (1 click)
3. Install battery
4. hold down (and keep holding) volume up and volume down
5. insert USB cable
6. depress (i.e. don't hold) power button
Goes straight to battery charging indicator.
If I swap #6 with holding the power button down, it continually reboots while just barely showing the battery charging indicator. I've tried letting go between black screens on the 1st, 2nd, 3rd, 4th, and 5th black screen. Still no android dude with the shovel.
Try all the steps you stated but not the last one where you press the power button. Don't press the power button.

Pull out battery for 10 seconds, hold volume up + down, connect usb into other usb port.

Trying to get into recovery mode gets me the at&t logo and the "jingle", but no recovery mode menu to reboot, etc.
This is what I'm worried about, restoring the Rogers stock over top of the Odin 1 click restore (which is an AT&T image) has bricked it and prevents download mode from invoking.

I know, I played with adb before I bricked it. ADB needs to "see" the phone, it no longer sees it (I have three computers, all three can't see it, but they can see my friends cappy with no problems first time, every time). Same process for his phone works every time to get into download mode, but not on mine.
And yes, have tried other USB ports on the same computer, both on the mainboard, and on the front ports.
Keep the ideas coming though please, I will try every one.

There's a trick to prompt download mode through a "jig" which you can hack together for about $2 in parts and a sacrificial microUSB cable...it works on the other SGSes, but I think it should work on the Captivate as well. Never tried it personally...

I work in a tech shop so have access to electronics, sacrificial cables, soldering irons, resistors, caps, etc.... could you point me in the right direction?
Oh, nevermind, found it in the i9000 forum. Will test first thing in the morning!
Cheers,
I bricked one today as well. Exactly what you are talking about here. The only thing is that i was still under the 30days so i swapped it out for a new one. As of right now ive been debating whether i want to do the voodoo fix (which i think is what bricked it to begin with)
Ok, so I had my Captivate flashed back to stock and had it rooted. I decided to update from JF6 to JH7 through Kies Mini. After it finished updating, my phone was stuck at the Samsung Galaxy S screen and then it turned black, but the buttons still light up.
I already tried doing the 3 button recovery/download mode in every way possible, but my phone won't seem to go into recovery mode or download mode no matter what I do.
When I leave the usb cable plugged into the phone as I turn it on, my computer plays the notification sound where a device has been connected, but still black screen on the phone. Happens when the AT&T screen loads, wonder if that would help somehow
Please help!

If you had usb debugging enabled you can send a "adb reboot download" or "adb reboot recovery" command to reboot the phone. If not then you probably have to make one of those usb jig's with the 301k resistor.
But you should still be able to enter download mode if you pull the battery, press the vol up/down and put the battery back. My stock phone couldn't enter recovery but it could get into download mode, keep trying.
Hmmmm. Still doesn't work when I pull out the battery, plug in the usb cable, hold the volume + and - down, and put the battery back on. It just shows the battery charging.
i have something similiar just have battery showing and wheel spinning when connected to pc or AT&T logo flashing if powered on and can't get into download mode...How does one get back to reality at this point.
your phone does not have the button combinations required to enter either download or recovery mode. I guess what you should have done before doing anything to your phone was test the button combinations in case something screwed up. then you should have flashed stock with the odin package posted in the development forum with the 3 button fix. I had to do this for my friend's captivated after realizing the button fix was disabled, but I hadn't broken the booting of the phone then. but now to fix it, other than trying to use adb to reboot into download, I have no idea what to do.
Looks like you'll need to make a JIG. Here's one thread on it:

Made a jig with parts bought from Radio Shack.
the jig was a success to get the phone back to download mode
Hate to be that guy, but alas I am
I flashed my Captivate with the latest Twingerbread ROM. Everything was running nice and smooth until I decided to use a Galaxy S Mod tool from the market place to change my battery icon.
Long story short the phone is now stuck trying to boot. It will run the Twingerbread loading animation for a few seconds, flash a screen that says
Candidates:
Preparing external SD Card
and then continue with the loading animation.
Before this happened I had been able to force download mode using only the volume up/down buttons, that is no longer the case. I have tried using adb to access and force download but the phone isn't found whether powered off or in it's current "loading" state. ODIN is able to recognize it as a COM:7 device but fails to flash it.
I'm in a bit over my head here, anyone have any suggestions on how to fix this?
Try this:
Open Odin and plug the cable into your computer only not your phone
Remove your battery from your phone
Wait 30 seconds and put it back in, don't turn your phone on
Hold both volume buttons down and then plug the cable into your phone, it should go into download mode.

Thank you for the suggestion but I can't get that to work for me. I tried it multiple times but it simply loads the charging screen. I have heard the term jig thrown around a time or two in here but can't seem to find any more info on it. Would that be my next step?
Yes if that doesn't work then you will need to get a jig to force download mode. Look here....http://www.mobiletechvideos.com/blog/?page_id=100
Good Luck
Nice, I don't have to make it even. Thanks for helping the noob out, jhernand1102. Hopefully this cures my issue.
Second time to edit this post...
Tried to get S7 on and it got stuck at do not turn off target. then screen went black. Not sure what happened.
Phone wouldnt turn on but would go to download so i attempted to flash it back to stock with I897UCJF6-Final-OCD-REVO
That successfully completed 100% unplugged the phone and powered it up and now it is stuck at the "AT&T World Phone" screen
It just sits here and flashes over and over about 10 seconds on and 2 seconds off and never gets past the AT&T screen. If I hold the vol up down and power it goes to the battery charging screen and does the same thing.
Any ideas?
Phone still wont do anything and will not go into download mode.
Have you ever used that JF6 package before? What build is your phone? To get in to download mode you can take out batter, open odin (run as admin) connect phone to computer (rear pc usb port) press key combo and insert battery. If that doesn't work make a jig.
bad part is i just got this phone from AT&T. I had some other issues with my old one that had 'dipity 6.x on it.
So thats what im dealing with. STRAIGHT out of the box and tried to get the newer version of dipity on it and trashed.
No matter what I do it wont go to download mode... Im on a laptop and ive tried every port available with no results.
Using your method of putting the cable in without the batt and holding the buttons im getting same result.
Ive used this ODI before on my old phone, so i know its worked before.
If that phone came with froyo then it will bootloop with JF6 odin. Get in download mode and ODIN a KB1 package somewhere in the dev section.
If thats all that is wrong with it im going to flip. I appreciate your help.
Well let us know if it is =P
While flashing a kernel/rom over to my tab I lost power... So the device seems to be hard bricked. Doesn't turn on no back light no icons of any sort. Left it plugged into usb wall charger over night and still nothing. I have searched the forums and have come up with no solution other then sending it out and paying to have someone fix it.
I am comfortable taking it apart and have done so already trying to follow this guide http://forum.xda-developers.com/showthread.php?t=1312391 however its a no go because I have a VZW tab the sch-i800.
So any ideas on how to fix it without sending it out and paying for a fix?
I don't own a CDMA device,
but my understanding is that it is hard to brick the tab just by losing power during flash.
The bootloader is very small so flashing should have occured fast at that area of the chip.
Unless your battery is literally at 1% when you flash it.
Now you can't go to download mode at all? (Vol-Down + Power)
I can not in any way get any menu or image or even back light to turn on with any combination of buttons. I think if only the tab lost power it would have been fine but the computer I was using to flash with lost power due to a local outage.
have you tried pushing the power button down for about 10 seconds (in case it is not fully down)
Yes, after hours of being plugged in to usb wall charger, with the cord that shipped with the device holding power + vol up/down or anything else, yields nothing. However the back does get warm as if the device were on. I only know this because I tried this test with the device out of its case, and was able to feel a small amount of heat off the back plate covering the mobo chips.
but have you push the power for 10 seconds or more?
If still feels warm, means it is not yet powered down completely
Yes I have tried holding the power for up to a minute, I can power the device down rather easily seeing that the case is off and the battery is easily removed.
Lots of recommendation to preconnect to Odin and start up the device in download mode.
Sometimes Odin will see the device added suddenly even when device is dark.
Then quickly flash the rom when it happens.

Try what Priyana recommended (Start up Odin, plug your G-Tab to your PC, and press power and vol down to go to download mode), and see if odin can detect your tab. You might get lucky.
If not, check this thread, it is the unbrickable mod for the CDMA:

I have been looking for that post, thanks. I'm going to give this a try but it might take me some time due to not having my soldering iron around. It might have to wait until I head back to college.
