Got stuck here working with a friend's captivate. We were in the process of cobbling together a jig when we notices that Odin seemed to recognize the phone whenever it was at the P!C screen.
The jig wasn't working out (resistors were 5% weaker than nominal), so we just gave Odin the go ahead at the P!C screen. To our surprise, a progress bar popped up on the phone and Odin successfully flashed the stock kernel back on.
So my question is, is the P!C screen just another face for download mode? Do you really need to jig from P!C to DL mode, or are you already there?
Not 100% of the time, but most of the time yes.

Cool, that makes life easier. When it isn't, does Odin not pick it up? Or does it show but fail to flash? Just trying to get an idea of how these things act when they're pseudo-bricked. I'm coming from Droid X land where 2nd-init and SBF solve everything.
Odin will only find the phone if it can get into download mode. (Usually vol up + vol down > plug in cable)
Not true, Odin shows a com port when booted into Android and in recovery. But will only succeed if download mode protocol is initiated on the phone.

And to further add clarity, it's only the phone-!-computer screen that says "Hardware Upgrade Failure" (or something like that) that doubles as download mode. Coincidentally, that is only found in Gingerbread bootloaders. Happy Flashing
"Firmware upgrade failed" and even that's not completely true...if the flash you're attempting fails before the image for download mode is rewritten, then when download mode is initiated there is nothing to call on but that "flash failed screen" regardless of bootloaders.
That happened to me on my sisters captivate once...with eclair boots.

Weird. So, that would explain our situation. The flash failed while it was trying to negotiate the connection with the phone (or something worded like that, one of the first steps). So this jig is for real huh... Nothing like that in DROIDX land. Now that we've got it built right (no multimeter at the time, 301.6k ohms now) can we test it without altering anything? In other words, if we initiate download mode with the jig does any other kind of hard reset happen? NAND wipe or something like that? Or can we jig in to download mode to test the jig, then battery pull and reboot normally? (without plugging it in to a computer obviously - just a dry run)
Yeah, forcing dl mode shouldn't hurt anything. How do you think they test the ones that they make?
And you don't even need to yank the battery..just hold all 3 buttons and it'll reboot, if you hold them slightly too long it'll boot into recovery, but you can reboot it from there no big deal
Nice, thanks for the tip. I'll test it out tomorrow and see if my handiwork paid off. These unlocked bootloaders are fun! I do love my droid x but maybe the Verizon Galaxy S (fascinate?) would have been a good pick too.
Tangent: my friend is now up and running with the Corn KK4 7.06 under the stock ROM, got his root back. Next step, rom land.

I had loaded the ginger clone rom and all was well. I then however wanted to swap kernels so i loaded up seitrons cwm 1.5.6 and proceeded to flash through cwm. this has now become the worst day of my life. the phone will not boot past the galaxy s screen. i cannot not get into recovery and both computers now say usb device not recognized when in download trying to flash odin. i am worried that something is corrupted on my phone because not matter how many times i uninstall and reinstall the drivers no luck. i think it is officially bricked and im sol. maybe some great minds can figure it out here.
It's not bricked - issue is trying to get your computer to recognize your phone when in download mode so you can flash it back.
What OS are you running? Also - where did you download the drivers from? Some seem to work better than others.
If you can get to the galaxy screen you might still be able to to get into recovery. pull out the battery and use the 3 button combo. Hold down both volume button then power and let go of the power button after it turns on. then just reinstall the rom
I'm willing to bet you can also get into Download Mode either with button combos, or a JIG. Once in Download, you can use Odin to restore to JF6, and have a working phone to flash around with again.
i can get into download mode no problem. and i think it is quite possible drivers are corrupted on the phone itself. my wifes phone works on the same exact setup. no usb device not recognized error. i have tried the drivers from here and samsung directly with no luck. 3 button combo does not work. sim out sim in battery out and in. but like i said it will just not register with the comp and hers will. so im going to att and seeing about replacing it. but i will see how that goes. ive done this lots of times with no issues ever.
download works
3 button combo does not so no recovery
usb device not recognized error
thanks for the help and keep it coming i will try everything if i haven't already.

Think I'm in worse shape. Tried flashing just the kernel to get BLN working again (last ROM I put on somehow loaded a non-compatible kernel). Now the phone boots the white ATT screen and just sits there. Can't get it into D/L mode with 3-button and doesn't respond to computer I have been using to flash ROMs for a couple weeks now...
Am I hosed? ANY help would be greatly appreciated...
You could try to use a JIG to force your phone into Download Mode
Okay...well, got into D/L mode finally. Used Odin to get it back to factory. Used the One Click rooter again, except now it boots to recovery 3e, which doesn't let my power button work as the okay button Pulling the battery to reset it, but it will no longer go into D/L mode to use Odin again. It keeps booting to the recovery Utils, which I cant get out of...*sigh*
Thoughts?
at least your able to do something i still cannot get my phone into recovery or to be recognized by the computer. it is not the drivers so i have no idea. i can only think that something got funked up with the kernel flash.
if you are getting into 3e recovery then you are most certainly NOT using the JF6 one click stock
3e recovery comes on JI6 which is the FroYo leak....completely different builds and roms
have you tried a different usb cable? I was having this problem, and the stock samsung cable was B.O. and wasnt working... i tried my blackberry one and all was good

I just want to quote this to stress the importance.
Thank you, didn't realize that (still sorta new to this)...
I downloaded a zip (I thought from here somewhere) that extracted into the 4 files. Anyone got a link to the JH6 set of files?
I also downloaded DG's "One Click Odin", but it doesn't seem to really do anything when I run it unless I manually load all the files. Also, I don't see a "Master Clean" like the post refer too
are you sure you downloaded the right odin? in the one click version, theres no option to load files at all. only a "start" and "master clear"
make sure the odin one click is open before you connect your phone.

I was having the same problem. Have you tried powering off, start odin, hold both the volume up/down, then plug in the usb to your phone?
Hey all, just got my Captivate 2 weeks ago and successfully rooted and flashed with custom ROM following the directions on all the posts here. Last night, while attempting to switch from Paragon 3.0 to Phoenix 4.0, installation was aborted. After several unsuccessful recovery attempts through CWM, I finally followed directions and used Odin-one-click. Odin did its thing and phone rebooted immediately and got stuck in a loop.
ATT screen flashes on and off when phone is powered on. When plugged into PC, phone flashes empty battery and computer does not see the phone. I've tried just about every button combination I've come across and about every permutation of button/battery/USB/Odin combination on the PC to no avail.
Is my last resort the USB jig? Or are there other options? Any and all help would be appreciated. And thank you to all of you whose posts I used to get me this far.

Not sure if this is how you got into this situation in the first place, but did you disable the lagfix before flashing? If not, it may be what caused this.

So I was trying to go from serendipity 6.4 to 7...
I was following the directions on the serendipity site, got to the point where it was supposed to be flashing the new boot loader and gingerbread. Odin sat on "zImage" for about 15 minutes before i decided for some reason that it was frozen and that unplugging it and trying again might help...
now the only thing I can get from the phone is a black screen with red and green dots when i try to get to download mode.
any suggestions??
Elliot
zImage is the kernel. This should recoverable
Did it get passed boot.bin and sbl.bin? If so you've got the new boot loaders. vol down and power to get to DL mode. Since odin hung and was disconnected before completion the image for DL mode might not even be on the phone. Try that combo (or better yet a jig) then whatever screen it boots into hook it up to odin and try flashing just xcals gb kernel. If it's not in DL mode it will just hang on "setting up connection."

Assuming im not completely water-headed, there should be a screenshot of my odin attempt, for your viewing pleasure...
if thats the first fail, then the bootloaders were never flashed so try the old button combo... switch usb ports first of all no matter if you try the next peice of advice or not anytime odin fails you should swap usb ports(always making sure its on the back, no hubs or front ports)...open odin, hold volume buttons and plug in usb chord on your phone...
a jig is always a good idea... i made mine before i ever flashed anything so i knew i would have an out if things went sour.

finally got it to download mode, but now im frozen at "param.lfs" after "firmware update start"...
Thank you so much for the prompt help studa, I really appreciate it
Hmmm...not your day huh? If it's frozen you have no choice but to disconnect. All the damage has been done. When you disconnect now you will most likely get the "clay" screen: phone....!.....pc and like I said before the download mode image might be missing. But this should still be recoverable
What version of odin is that? The earlier versions tend to freeze up more. go to this thread http://forum.xda-developers.com/showthread.php?t=979133 don't worry about the firmwares just at the bottom there is a few versions of odin. 1.7, 1.81 and 1.82 try one of those.

hey, i am posting this for a friend who bricked his phone and doesn't know much about it..
he was running serendipity 7 which is a jvo rom, and tried flashing the pauldiddy remix theme, which says is only meant for jvp and jvq roms. i used a jig, to get the phone into download mode, and the computer detected it when i plugged in the usb. but when i tried to use odin one click to go back to stock, it would get stuck at the "Do not turn off target". im not sure if anyone knows a fix for this, or if i should try using the method from this thread http://forum.xda-developers.com/showthread.php?t=1153310 instead, but i figured i would ask before i messed around with it too much
any feedback would be appreciated
how long do you wait before throwing in the towel? it does take a minute or two to finish it's task ? And are you opening Odin before you hook the usb to the phone ?
waited probably about 5-10 minutes. yeah i opened odin first, and it detected the phone and showed the Added! text
Just out of curiosity, what is the phone doing right now that you're trying to use Odin on it?
The reason I ask is that if you can get to CWM recovery, you might just be able to re-flash the rom (assuming it's a wipe package) and it would take care of the issue.
i cant get into recovery, but i can get into download (using the button combos). not sure if that means anything either
Well keep trying, and you might want to try the odin 1 click. I have a Cappy that got dipped in the pool, it would not go into recovery at all but I could get the download all the time, But it kept getting stuck at the i896 screen or the AT&T screen (odin 1 click) after 3 weeks of trying and having to wait 3 days for it to come out of it's coma it now works fine. If you try the odin 1 click it might work for you just make sure it's not ver 10.10 I think (look under battery). What screen does it go to once you press power IE: black screen rogers screen etc. ?
ive tried using odin 1 click.. like i said, the first time odin actually picked up the device, but it wouldnt get past the "do not turn target off" prompt. but i tried plugging it in again, and now it doesnt seem to even pickup the phone. when i when i try to boot the phone, its just a black screen. thanks for the input though
hey all, i've had my captivate for about two years now, and for a while i used cognition, then for the last year i've been using firefly. firefly has completely destroyed my phone's speed and responsiveness, and i needed to clean everything off and start with a minimalist ROM. so i picked slimICS.
i'm still very hazy on the details and terminology of flashing ROMs, but i got two to work (i remember using one-click root thing in 2010, and then in 2011 i flashed firefly through clockwork) so i figured it shouldn't be a problem to install slim, which i figured would be my last ROM until next year, when i'd get a new phone.
so i backed up my stuff, tried to get into recovery mode with the 3 buttons (didn't work, unsurprising since it didn't work last year either), took out my SIM, went to CWM, and selected the flash rom option. this restarted the phone and sent it into recovery mode--except it was the stock recovery, and i couldn't select anything because i think firefly made the phone think it was the i9000 model from canada, instead of the i897 captivate, so it assumed i had a physical "ok" button on my phone (which i obviously do not). i tried the power button, the various capacitive buttons on the bottom, nothing would select any of the options, so i just took out the battery and put it back in. the phone immediately booted into the CWM recovery menu, in which i selected flash ROM, and scrolled down to choose slimICS.
i let it do its thing for a while, it jumped between the AT&T white logo screen and a screen with scrolling text for like 5-10 minutes, then just stayed on the AT&T logo screen for another ten minutes. i should have left it for maybe a half hour to be sure, but i figured the install failed. i couldn't get out of this so i pulled the batttery. and now the phone is bricked (soft i hope). if i hold the power button it goes to the AT&T white logo, flashes briefly for a half-second and goes back to the screen, then stays there indefinitely. no button combinations seem to work. does anyone have any suggestions?
thanks!
Since you backed everything up, I'd suggest flashing a stock rom via Odin or Heimdall to clean everything up before moving forwards.
You can flash a non-bootloader one to be safe, or if you want to make sure you can flash anything, flash a package with Gingerbread bootloaders.

how do i flash anything in my phone's current condition? it doesn't turn on fully. it's stuck at the white AT&T logo.
Turn it completely off (pull the battery, if necessary), then hold V+ and V-, and insert a USB cable. That should put it in download mode. Once you're there, you can flash a stock rom (There's a stick with those roms in the development section).

doesn't work. as i mentioned in the OP, i can't get into download or recovery mode or whatever. these button combos have never ever worked with this phone. for example, holding + and - and inserting a cable with ODIN open has never done anything. that's why i used clockwork.

is that guaranteed to work? or is it most likely? or is it unlikely at this point?
The jigs that I have made myself in the past and as well the professional made ones that I have purchased have always worked to get me into download mode.
The jig is worth a try, I suggest you should
if I'm reading the op right, and if memory serves firefly was an I9000 build and button combos are different. My suggestion would get the Odin kk4 one click with repartition and WITH boot loaders from 4-2ndtwin's sig links, open that and while powered off and holding just the vol- button insert the USB that should do the trick. I9000 builds use different boot loaders with different button combos. Since you will be flashing a boot loader package be aware this is when you can truly hard brick your device. Be sure you have a good connection and cable before starting. If you still can't get into download mode I can +1 on the jig. The jig and 4-2ndtwins one click has saved my bacon more than once.
ok so i bought the jig, and good news: it gets me into download mode! yay!
problem: i don't know where to go from here. i've tried the following:
A. after getting into download mode, i followed the ODIN method here: http://forum.xda-developers.com/showthread.php?t=1350266, meaning i flashed the gingerbread bootloader update (nothing happened to the phone, which made me confused when i got to step 7., because i was STILL IN download mode), then flashed the speedmod kernel (which reset the phone, but it just got stuck in the "SAMSUNG CAPTIVATE i-897" white text on black screen, forever. i had to do a battery pull. turning on the phone goes to the same screen and then it freezes. trying to hold all three buttons to go into recovery mode alternates between that screen and the white AT&T screen, actually alternates, forever if i let it.
B. after that failed, i tried using the 2.2 Heimdall one-click (http://forum.xda-developers.com/showthread.php?t=1266172) but the file, when run, says
Code:
ERROR: Drivers Not Found
Installing drivers
but i still followed the instructions (except the instructions say "Install driver" but the actual button is "Replace driver"?) in any case, this does nothing. and then checking off "Flash bootloaders" and doing it again does nothing. the phone remains in download mode.
C. so i wanted to try one-click downloader http://forum.xda-developers.com/showthread.php?t=731989, but nothing pops up on the ODIN window when i plug my phone in. i can't even do anything.
please help!
please, does nobody know what to do?
Take a look at the "Captivate Connection Issues" thread for some more things to try. At this point, it sounds like you need to clear all the phone drivers off of your machine and reinstall them.

thanks, that worked! (it was my laptop that was the source of the connection issues i think; i tried all that stuff in the thread, but when i switched to the desktop, all of a sudden ODIN recognizes the phone!) i got my phone to flash ODIN one-click. so now i'm back to stock 2.1 eclair.
however, much to my dismay, i still can't get into recovery mode to (re-) root. the three button combo still does the weird flashing thing, where the white AT&T logo shows up, then the screen goes to black, then the AT&T logo, then black... ad infinitum. how do i either 1) enter recovery, or 2) re-root the phone + get a nice, lean, fast, modern ROM on it without going into recovery?
so far this thread has helped me unbrick the phone, now all i need is to update it from stock!

I could be wrong but when you do the 3 button combo it sounds like you are continually holding the buttons which will cause it to keep looping like you describe. Starting with your phone off hold down all three buttons. The phone will show the white ATT screen. Then if you had a custom kernel it would show the kernel splash screen, in your case you said it just goes black which is fine too. Then you will of course get the white ATT screen again. As soon as you see the white ATT screen again release all the buttons and that should boot it into recovery.
