PC won't recognize phone in download mode - Captivate General

So I was trying to use Odin to reflash to stock and try our SRE 2b7 and something happened where Odin froze up.
So I tried to start over and I can get into download mode fine but I can't get my PC to recognize the phone. I keep getting "your USB device has failed" error message.
Tried reinstalling the drivers several times.
What now???
ETA
never mind I kept messing with unplugging and re-plugging removing the battery etc and even though the PC still gave me that error I got Odin to recognize it, flashing now

[Q] completely bricked

Had serendipity vii, tried to install a theme. It bricked the phone.
used odin 3. restored the phone to factory.
tried rooting again and tried to put serendipity back on
didn't work
tried a bunch of different ways
then on my last attempt used odin to try and load serendipity vii. it stoped at "get PTI for Mapping...Firmware update start...Removed!...Completed. All threads completed (succedd 1/ failed 0)
now the thing won't even start in download mode or samsung screen.
the only thing I can think of is the battery died. but its been plugged in for a while now and still the thing is dead.
any ideas out there for the n00b?
Im beyond my limited capacity...
thanks
First make sure your using the factory Samsung cable. Your battery may have died but you should be able to get into download mode without the battery. Start Odin >plug cable into computer > volume down > plug in cable.
Too late now but, I don't believe you can use Odin to install Serendipity, thats probably what bricked your phone.
I think the PIT is screwed up - gtg's ultimate unbrick does include a fixed PIT.
The following has never failed to enter download mode for me:
Pull battery and reinsert
DO NOT power up
Hold VolUp + VolDn while inserting the USB cable into the phone
Note that if things are really screwed up, download mode shows a different screen - a "phone-to-PC" instead of the usual "android construction worker" screen.
and even while it shows that screen u can still restore, try the GTG unbrick method , it should work.

Odin not working?

So I rooted my phone with SuperOneClick, then tried installing CyanogenMod, but it kept failing. I read somewhere that reflashing the original kernel via Odin could help, so I tried that, but it failed. So I restarted Odin, tried again and it got stuck at "SetupConnection". Eventually I just restarted the phone, but that was a terrible idea, as now I can only see a screen saying a ROM installation went wrong, and to use Kies to fix it. BUT I can still get into download mode, but Odin is still doing the same thing.
Anyone know what's going on?
Probably might have to return to stock with Odin. Maybe just try flashing the stock recovery with Odin first and see what that does.

I've been trying to flash to stock with Odin. And recovery. Nothing will flash. Some problem every time.
Hold both volume buttons on the left side of the phone, and then plug in your usb cable. You should be in download mode.
...I know what Download mode is. I've been there the entire time. That's not the problem I'm having.
Whenever I try to flash anything using Odin, it fails at the NAND write, then if I restart Odin and try again it hangs up at SetupConnection. This happens with ANYTHING I try to flash. And now, if I try to boot the phone normally, it goes to a screen saying there was a firmware error and to enter recovery mode in Kies, which I can't do because Kies won't connect to the phone.
Try using a different cable. I got the same error using my longer USB cable, but switching to the original cable from the box helped.

Question regarding odin (solved)

Ok I have looked at thread after thread and saw some similar issues but no real solution that has worked for me. Long story short, my brother tried updating his SGS4G and "says" the cable came out during update. Basically phone was stuck in communication with pc screen. After tons of trial and error button combos, jig, etc. I was about to give up as I couldn't get it into download mode. Well got bored so tried again and somehow got Odin to recognize the phone and started to flash the K1. Unfortunately, it failed before completing and now I can get the phone into DL mode but Odin nor the PC will recognize it. It sort of boot loops a couple times then loads up to home screen for a few seconds during media scanning then trips right back to Galaxy S 4g screen and starts the boot loop deal over again. I was able to check before it cut off and it has unknown baseband. Is there any other way to get Odin to recognize while in download? I have done all the steps then plug in phone etc. Odin just sits there and PC said usb not recognized. Tried 3 different PCs with XP, Linux, and Win 7. Is the baseband the issue for getting it recognized now? If I can ever get Odin to recognize I was hoping to manage a full backup to stock and then worry about the baseband issues but for now I am stuck and would have pulled all my hair out by now but I am bald. Any advice or pointing in the right direction would be great.
Edit: Thanks for the help. After tons of attempts I got Heimdall to recognize and got it flashed back to stock.. Still isn't recognizing all the time but hopefully it will enough to allow me to root it before I give it back to him. Thanks again I read and read and tried all sorts of stuff multiple times.
If you can get into download mode. Just start ODIN whether it recognizes phone or not and see what happens. And double check your settings are correct in ODIN. Make sure u have latest version as well. Or try Heimdall.
EDIT: Go ahead and tell us whether you were on FROYO or GB. And why were you flashing K1? And what is K1? KC1?
Are you using FB's GB Ext4 Starter Pack?
Odin can sometimes be a pain. If the computer gives you the "un recognized device" keep trying. Tried different cable and USB port and reinstalling drives and such? Lots of others have had luck using the one click.. Heimdel package. But, I'm an Odin fan... If you get any sign of life from PC while it loops, that's a start.
if you have adb loaded, have you tired to spam the reboot download command while the phone loops?? Its another way to see if it does/can get into download mode..
Did you get it working? If so mark the the title [SOLVED].

[Q] samsung conquer 4g root help

I was trying to root my brothers phone and i made a mistake.
I was on odin starting root the process by installing the FC17 update and having the phone in download mode.
When i clicked start on odin i thought the phone was supposed to go from download mode
to installing the fc17 update, but when the phone turned on and it acted normal i thought something was wrong.
When i looked on odin's message box it said something about the connection being void until something happened
(i cant really remember what it said) so i decided to unplug the phone.
After i unplugged the phone i decided to restart the rooting process.
This time the download mode screen was different and had a warning about installing a custom OS, but i just ignored it.
The problem is this time around odin wasn't recognizing my bro's phone and i don't know what the issue is.
I installed the phone's drivers and the usb ports are fine. I also tried this on a different computer but it didnt work on that one either
so i figured the problem is that something messed up when i unplugged the phone. Odin now doesn't recognize the phone when its in download mode and i need help.

Please help! I think i'm bricked but I'm not sure

So I have/had a rooted Xperia z3v D6708 and tried flashing http://forum.xda-developers.com/z3/development/d6603-23-1-1-28-t3102271/ using TWRP recovery and everything seemed to go fine. I rebooted my phone after the flash but nothing happened. I tried booting into recovery again to try and restore my phone but nothing happened. I tried plugging it into my computer and it just vibrates every 2 seconds while flashing red then immediately green. This leads me to believe its not bricked so I downloaded the stock firmware using flashtool and tried flashing it onto the phone but when it gets to the part when it asks me to put my phone into flash mode by holding the vol down and plugging it in I do that but nothing happened. I also tried fast boot mode and that seems to work because the phone stops vibrating and the light turns solid blue but there is still a black screen and my computer stays at the screen instructing me to put the phone in fast boot mode so it never recognizes the phone. What should I do?
P.S. flashtool never recognizes the phone when I connect it but it does say this
17/009/2015 14:09:29 - ERROR - Drivers need to be installed for connected device.
17/009/2015 14:09:29 - ERROR - You can find them in the drivers folder of Flashtool.
I tried installing the drivers for my device along with the ones for flashing and fast boot but it didn't work...
Someone please help me!
Tried a full restore with the Sony PC companion? Usually at least gets you out of a soft brick if nothing else is working. Good news is that it's pretty hard to hard brick a sony phone when you're just flashing roms, so your phone is probably fine. I had trouble with the flashtool drivers actually installing because of Win8/10 driver stuff, so that might also be your problem if you're on those OS's. You might want to look into disabling 'Disable Driver Signature Enforcement' and trying again to make sure.
Google the disable driver thing he mentioned ^ I had the same issue and for future reference you can't flash any roms, you can only flash roms in the z3v sections, sound mods and other things like that should be fine to flash
