1. Try reinstalling to drivers. Also make sure you're using the same USB port as Windows can be funny about it it sometimes.
2. if download mode is being difficult, go download the Android SDK from www.android.com. Install it, run it, and only download the platform tools. When that's done, open a command promt, CD to where the plaform tools installed (either c:\program files\Android\Android-sdk\platform-tools or c:\program files (x86)\Android\Android-sdk\platform-tools ), then issue the command: adb reboot download.
3. I suggest you check the dev section for bhundven's one-click collection. Uses Java and Heimdall vs. ODIN and works easily.

Get it back into download mode, go grab a bhundven's one-click. The one-clicks utilize Heimdall vs. ODIN, which means they use open-source USB drivers instead of the proprietary Samsung drivers. See if that enables the computer to see the phone. If so, flash the one-click

Should I uninstall the samsung drivers prior to using Heimdall's One-Click?

That's a good idea. Some people have reported conflicts between the drivers.

Why would only Odin 1.85 see my phone in USB Debugging and not in download mode? And all other Odin verisions never see my phone, no matter what state it is in... I am at work so I will give the one click another try when I get home. I never thought of uninstalling the Samsung drivers prior to install; however, I did use the one click method to no avail. However, Heimdall's one-click was able to see my device it just kept giving me a driver error. This is so crazy it might just work.

I wish I had a good answer. ODIN's a funny animal. I've been fortunate and not had any problems with it. I am hoping you are correct - maybe it was just a driver conflict. Let me know how it goes.

didn't work...

You could try downloading a terminal app from the market. Open the terminal and type:
reboot download
See if that does it.

***Update***
Okay, so Oneclick was not working at all no matter what I did with the drivers. However, in all my tinkering with it I installed the Samsung Driver, the Open Source one, and some gadget driver as well from oneclick.
Doing this put all these drivers in my computer. Then I went into my Device manager (Win 7) and looked at my USB driver and I uninstalled everything and went to the stock win 7 usb driver. Then I plugged my phone in and my computer began searching for drivers for this device when it decided that it would be a good idea to load all three drivers at once and voila my phone was then showing up on ODIN 1.85.
I then proceeded to flash my phone with a rom, probably the wrong one considering I was coming from 2.3.5 and my phone boot looped and then soft bricked(sorry if I used these term incorrectly, noobin it).
After, some nervous moment of scouring XDA I found the god-send of a post on getting in to download mode, using odin, and flashing stock 2.3.6 - thank you Raver(I believe). When I did this, my phone magically started obeying ODIN like a devout viking and is now running 2.3.6 superbly.
Keeping with my phones newly found viking heritage, I intend to figure out how to properly root it, update the kernal and modem(not sure which one is best), get CWM, and subsequesntly put in Valhalla Black.
Seeing as though this last rendevous with flashing caused me a little scare I may hold off and wait to see what the next big update is (maybe a port ICS variant) and then go with that.
Anyway, thank you Stephen for helping me out with this and to everyone in this post.

Here's some reading for you Tytan,
http://forum.xda-developers.com/wiki/Samsung_Galaxy_S_4G#FAQ_.28with_answers.29
PS: Unless you wanna brick your phone, do not flash anything that isn't intended for the SGH-T959V Samsung Galaxy S 4G. You're saying you wanna flash a Vibrant ROM. You can, if you want an expensive paperweight. Happy flashing!

2.3.5 may have been for vibrant...yeah I think I got lucky. I did it prior to knowing about xda.

How are you getting into download mode?
There was a post in another thread where the person apparently was using the power menu to get into download mode or maybe the adb command.
Have you tried both the old fashion volume +/- and plug in usb cable? Or the adb command?
Do you have access to another computer? Believe it or not sometimes just changing computers will make the difference.
Weird when I replied there was no posts other than the ones on the first page...oh well glad its working now.

[Q] Can't boot into recovery

I think i lost my CWM recovery after installing the MIUI Rom.Instead it just sits on the samsung screen. I read that if this happens, to Download sgs kernel flasher, CWM community kernel, and Flash kernel via sgs kernel flasher.But i've searched the forums and i can't find the downloads to these items. Also, does this require me to plug my phone into my computer in download mode? Because iv'e tried that with odin before but there's an issue connecting my phone to the computer in download mode. If so is there another way i could get CWM recovery back. Thanks in advance.

Community kernel is in the super infuse thread.... Stickied in the android development section.
Sgs kernel flasher is in the Google play.

Here's another option. Second post will get you CWM recovery along with Entropy's DD kernel from 11/27/11. After that you can flash what you want.

i dont think i'll be able to do this as it requires me to put my phone in download mode and i can't get my phone to show up while in download mode using any program like odin.

The Heimdall app installs its own drivers but you may need the Samsung drivers for this work. Maybe try with Samsung kies mini installed, which provides the base drivers.
If that doesn't work, try a different usb cable or port on your PC.

I just tried heimdall but i still couldn't install the drivers. My phone shows up as unknown device. So unless i convince my sister to let me use her laptop, my only other option is to flash the CWM Community kernel but the link is down.

Samsung USB driver download.
for Windows 32bit
for Windows 64bit
After installed reboot your computer please and connect usb test.
Odin Community kernel download.
http://www.mediafire.com/?v1jg2wz1d1ia714
- Unzip the .zip file, Run Odin3_v1.81.exe
- Place your phone into download mode (pull battery, hold both volume keys and plug the USB cable)
- Your phone shows in Odin as COM##
- Click the PDA button and choose the .tar.md5 and start.
- After completes, it will reboot your device and should boot up normal.
CWM test, turn off you phone, hold both volume keys and power button boot to CWM (red or green menu)
(Sorry, I'm not good in English )

So, you can start up your phone ok but you can't get into CWM?
I'm no expert but I've learned a lot after bricking my phone! One thing I discovered is that Odin doesn't have to be able to recognize your phone for it to work. So long as you can get a yellow light in the first box, you're good to go. Also, sometimes the yellow light won't show up. In that case, try turning off your phone, pulling out the battery, and letting it rest for 5 or 10 mins.

Sorry for not replying to anyone. Another member reuploaded the CWM community kernel for me and I got my recovery back. And I don't think Odin will ever work for me because I have the drivers installed but it still shows up as unknown in download mode. I've already tries heidnall one click to install the drivers but it doesn't install them as my phone shows up as unknown.

[Q] Did I brick my phone? [Solved]

Hello all,
Firstly thank you for the great development and help the community is providing for GS4G. From the time I bought this phone (few weeks ago), I have been playing around with different ROMs. I try GB roms and ICS roms every now and then. Always go back to GB using 1 Click's.
Yesterday when I was going the 1-Click Heimdall, it failed in between with some error. After this, I am unable to boot into the OS or recovery or download mode. It comes to a screen which tells me that the firmware upgrade was interrupted and asks me to use recovery in Kies. I tried this, but Kies does not even recognize my phone anymore. Windows shows my phone as "unknown device". I tried uninstalling and re-installing Kies, but still no use. I hope there is some way to get my phone back.
I read somewhere about a USB Jig that could get you into download mode. I have ordered it from Amazon and it may take a couple of days. Meanwhile, if any of you can help, it would be great. Thanks!

youre soft bricked, this is fixable. The firmware upgrade interrupted screen is the same thing as download mode. try reinstalling the drivers which i think are found in the sgs4g BIBLE thread. after that, plug in your phone and make it go to the firmware upgrade interrupted screen and see if it installs the drivers. read lumin's guide. it explains everything step by step. im going to try to link it here soon.

Thanks. I had tried eollie's Heimdall Stock KJ6 + Root. But, I don't remember seeing the driver installation window show up. I tried reinstalling the drivers through Kies couple of times and re-booting. But, still didn't work. I will try what you suggested when I get home.

You should be able to fix it. Goodluck

Sounds like you need to run zadig.exe in the Drivers folder of the Windows distribution of Heimdall.
If that doesn't work, right-click on (My) Computer, select Manage, then select Device Manager. In the panel that opens, find your device, right-click on it and you can then look at its properties and potential change the driver there.
(Yes, this kind of shenanigans is another of the reasons I really dislike Windows)

Ok so what you should try is downloading the heimdall suite
https://github.com/Benjamin-Dobell/Heimdall/downloads
Extract and open the drivers folder and run zadig. Click devices/show all devices and if your phone is plugged in and in download mode it should see it. Install drivers and it should say drivers successfully installed. Then run your one-click jar file and it should work.

I tried all this. But, still Zadig shows my phone as "unknown device" and does not install drivers for it. Tried USBDview to remove any instance of Samsung & Android from the drivers. But, still does not recognize my device. Any other suggestions.

Try different USB ports on your computer.
Install Ubuntu (not totally kidding on that one, it will install side-by-side with Windows)

When is that jig getting there? One time I had a similar situation and I built myself a jig and it worked like a charm. Phone goes straight into download mode. I dunno if this will resolve your situation but I'm pretty sure this isn't the first time we've seen someone with this problem and then after trying several different computers and USB cables we usually say maybe your phone's USB Jack is messed up? And then the thread goes dead.

Have you uninstalled any drivers? Download and install the drivers from the bible thread if you haven't. Like suggested, try different USB ports and different USB cables. Sometimes it takes more than one try for some reason.

Have you rebooted your comp at all?? If no that might be the problem.

SUCCESS !!
Thanks a lot for all your suggestions.
Here is what worked:
- I opened device manager and uninstalled ALL USB devices (Yes ALL, not just Samsung, Android etc) and unfamiliar Storage devices.
- Then I rebooted once so that all other device drivers could be installed.
- Then I rebooted a second time and let it install any remaining drivers.
- Then I plugged in the phone and it installed the driver and now it started showing the correct device name
- Now, I ran the Heimdall 1-click and it opened offered to re-install drivers. I did this.
- After all this, I was able to get 1-Click GB rom installed and now back to VB.
(I think the key was "uninstall all USB devices" and "reboot TWICE")

glad you got it to work. ive had my share of soft bricks with this device and it always takes something different to get it to run right. im starting to think that my computer is alive because of this reason because it just doesnt like to play nice sometimes. LOL

This is very easy if you have an att phone. If not you will NEED to get the correct FXZ for you phone and download what I am about to link here, then put the correct FXZ for YOUR phone in the same location as in the download, and run the batch file, while your phone is in fastboot, as simple as that. If you do this RSDlite is not needed.
Link to the post with the scripts:

Again as it is, that is ONLY for AT&T phone, and you MUST get the proper FXZ for your phone, if it is not an AT&T phone, and put the FXZ in the same directory as the rest of the files with the script.

1. Make sure your phone is fully charged (you can't fxz below 30%)
2. Install the correct driver and boot your phone to AP Fastboot
3. You don't have to extract the fxz file. just put them to C:/ as a whole
I recommend you read the instruction again

Obviously you have to get fastboot working. that should just be a drive issue, but you can try a new cable/ usb port/ computer. What rom did you have? you should be able to get into its recovery and flash again.

I was stuck in this same situation just last week, fastboot not being recognized and all. What operating systems do you have? I tried 4 (windows xp 32 and 64bit, windows 7 32bit and windows 8 64bit), and only xp would work a few times. So maybe you can try a friend's computer with xp or anything else. Which drivers are you using? because it worked for me with Motohelper, but not the latest drivers. Either way, keep trying different usb ports especially with the Motorola cable.

I see, that may be why it's so hard to get fastboot to work. :/ The A2 seems to only like working with the Motorola oem cable for many people, especially with AP fastboot. Well try what you can to keep the battery charged, and try what you can.

I would try using Linux. if you don't want to install it, you should just be able to use a live cd of ubuntu or something. it aught to work right off the bat, no drivers needed. you will ahve to use manual fastboot commands though, no fxz (so you will need to install moto-fastboot)

Heimdall will use the same methods as ODIN, just a different application.
Try a different usb cable. Try a different computer. try and track all permutations of combinations of cables and computers. Make sure you don't use FrontPanel usb connectors.
EDIT: to answer the question in the title of the OP, No. You cannot flash bootloaders without being in download mode, which you need to go back to "total stock" (say for a return).

Also you can try uninstalling the drivers and re-installing them..
I have had to do this before..
Sometimes the computer doesn't
want to recognize the device..
I don't know why but it happens.

This may be another case of broken usb connector on the phone itself. I've had to repair mine before and I recently sent back 2 phones that T-Mobile sent me as replacements both with broken usb connectors. The last thing to go is charging. Usually what happened to me was it won't talk to my computer or sometimes when I plugged it in to the charger when it was turned off it would randomly go into download mode.
