Please help...big problem....

Big problem. Suddenly my phone will not turn on. Sits at the white Galaxy S GT-I9000 screen and does not boot. When I put it into download mode and plug it into computer, its suddenly saying "USB Device Not Recognized".
What do I do? PC won't recognize it, it wont boot. can't flash it.....I'm freaking out here...

Did you flash anything to it or root it?

Hi Rick. Try to re-install samsung usb drivers. during this time, take out the battery from the phone. once finished installing the drivers, put back the battery into the phone. Go into downloading mode. Fire up odin, put in the necessary firmwares + pit files. Once done, then CONNECT your phone to the usb port of your computer.
Hope it's okay.
Edit: Let's hope that it is the computer usb drivers are corrupted. Alterntively, if you still can't do it, try it on another pc.

Nope. I was rebooting it to flash XXJPC to it, but couldnt do so because it was saying that USB message and wouldnt detect it. So I went into recovery, did a factory reset, and now it wont boot.

Another computer does the same thing *tears*

*BUMP*
Lets try a different route. I will pay a generous sum of money to anyone who offers to and does manage to fix this for me?

rick, looking at this, if your usb is not recognised, it is either the pc or the phone usb port might be damaged.
if it is a hardware issue, then use the bounty to get it fix.

I was at that same point with my vibrant. After failed attempts of getting into download mode using buttons, here's what I did.
Download and install samsung usb drivers and android sdk.
Plug into the computer and use adb to get into download mode (adb reboot download).
Then flash with odin.
Doing that worked for me when nothing else would. Try it ?

I can get into download mode just fine.....my pc just doesnt recognize the usb device. tried 3 differente pc's, 2 running win7 and one running xp.

Did you install usb drivers on each of the machines?

I installed the samsung USB driver executable. and I also tried to use those drivers that it installs to manually update the "unknown USB device" in device manager, but they won't take.

Try uninstalling all drivers, then stick a MicroSD in your phone before plugging it into the usb.

Assuming you have Samsung Kies in your PC, try to upgrade it at 1.5.1.10074_45.
How long do you wait the boot?? The first boot after flash is very long, wait at least 5 minutes with flashing "S".

I did not just flash anything. My phone got really hot and laggy (as I was using it while charging it via USB port) and so I rebooted phone in an attempt to resolve the lag. when I did, it would not go past the WHITE Samsung Galaxy S I9000 screen, does not get to the flashing S screen.

if i understood you correctly, you have two separate problems:
a) your phone does not boot up
b) your phone is not recognized by any computer when plugged in
could be a coincidence, but probably is not. i'm guessing your bootloader got screwed up somehow. if it is a coincidence, it could be that your usb port on the phone is effed, or your usb cable is dead. try first using a different cable and see if your phone can be recognized by any computer. perhaps then you can go into download mode and reflash.
also, have a look at this post, might help you (although, if your usb is effed, there's not much point in trying any solution that involves your phone being connected to a computer): http://androidforums.com/780720-post3.html
EDIT: also, have your tried the obvious stuff, like pulling battery?

I ve seen many threads with the white screen problem ... it has in most cases been the drivers ... you desinstall all drivers from pc using Kies option for resinstall the drivers ... then you pull the battery off few sec (give it a min or two) then you get to download mode and you flash the beast ... dont connect your phone before launching odin or else it will not be recognized ...
for the few other people who didn't manage to fix it ... it was a hardware failure

That post you linked, is worth a try. But its for a motorola.....Where do I get my SGS bootloader to use instead?

ohh you were implying to try to use the motorola usb drivers?

I never said anything about a white screen. and I am not uneducated on flashing SGS, or using Odin. Far from it. My phone was first showing USB symbol when it wasnt plugged into USB port, then phone started running really hot while charging and got really bloated like it was overheating. So I rebooted and its now force closing at the first boot animation. I can get into download mode and recovery, but will not recognize in any of the 3 computers all running different versions of windows on them, with either of my USB cables that I tried.

Need Odin3 1 click/stuck on boot screen

So I flashed my phone to Phoenix and was going wonderfully. Flew into St. Louis from Oklahoma and the phone froze up. It's now stuck on the AT&T boot screen. Occassionally after doing a battery pull and turning it on, the Phoenix boot screen will come up and I've gotten it to the lock/unlock screen but is unresponsive to touch.
Occassionally it even has what almost looks like colorful static on the screen. So now I'm in a completely different state without my home laptop for a week with the Odin3 1 click and am unable to find a download link for it.
Help would be appreciated. I was hoping to get the phone into recovery to try and flash back to stock or reflash Phoenix but it just stays stuck on the AT&T boot screen now.

remove battery, put battery back in, hold up+down vol buttons, plug in usb.
you'll be at download mode, then use odin.

Do you have an Odin download link? The Odin link on the site isn't good anymore and google isn't helping

here's an alternative link I've used:
http://www.mediafire.com/?0w2y31maz8mdom4

I appreciate the help so far and the Odin link. I managed to get Odin downloaded. I managed to get my phone in download mode. However, Odin is not registering that there is any phone. Normally I'd see a COM but nothing is showing up.
I started by running Odin.
Then got my phone in download mode.
I can't get any farther.

Do you have the drivers installed on your PC ? I also read somewhere where you have to have the latest net frame work as well...If you do...you might have a bad usb cord...and here in St.Louis..there are a lot of AT&T stores you can get one..
Mac

Well, on the original thread that had the link for Odin has the 32/64 Samsung drivers. I downloaded the drivers zip file to the desktop of the laptop.
One thing I find strange is usually when I plug in the phone to my laptop with the USB cable, the option to view files, etc pops up. It is not on this laptop.

Did you install the drivers then ? Sometimes my wife's Samsung laptop does that..and not install anything going to the desktop..If everything is loaded correctly..you 2 drive pop up windows should open..
Also (I'm sure it is) make sure usb debugging is checked on your phone..
Sometimes the most simplest things keeps things from working correctly..
Phone unplugged..in normal mode..usb debugging checked..do not mount phone..
Close Odin
Open Odin
Plug phone in
Put phone into download mode...click start...not master clear...

Odin is also finnicky about USB ports. If you are on a desktop machine, try using one in the back instead of the front, or if you have multiple sets, try using a different one. I've had Odin not recognize certain USB ports but recognize others before.
Finally, I suspect you already know this, but for sanity's sake make sure you start both the PC and phone up fresh after reboots, open Odin, then connect the phone. Connecting the phone first breaks Odin.

What OS are you running? Are you explicitly starting odin in administrator mode (right-click->run as administrator)?

Okay, so I switched USB ports and it suddenly recognized and it started to download drivers. But it was listed as a gadget Serial and no drivers found. Geez this would be so much easier if I was at home where the laptop is set up with everything instead of being several states away.
Okay, so apparently I do not have the correct drivers installed. I really appreciate all the help so far. At this point, should I just google Samsung Captivate drivers or does someone have a link handy?
I can't get to my debugging as the phone stays on teh AT&T boot screen. I did have it enabled before I left OKC though.

I've gotten teh Samsung modem software successfully installed.

I know. Flying from OKC to St. Louis and then from St. Louis to Baltimore with a several hour layover has me exhausted and not thinking clearly.
I did manage to reboot it and Phoenix came up. All drivers were showing ready except for ADB and then the phone shut down and ADB said phone was unplugged.
I feel like I'm making headway but just not there.
And why is it I'm staying in an expensive hotel and you still have to pay for net? Geez

I downloaded the 64bit drivers. Ran the exe file.
Extracted Odin and have run it as an administrator
Put the phone in download mode.
Odin is still not seeing anything.
NM....pop up box just said taht device driver software not successfully installed. I think I'm going to hit my head against the wall for a bit.

[Q] ODIN doesn't see my phone in download mode.

Phone is ATT captivate SGH-I897 1008
Had my phone for 4 months or so, most of the time with cognition 2.x on it. Tried to update to 3.02 yesterday, and it had an error in the middle, left me at a recovery screen of sorts, and I chose to reboot from the possible selections. It got stuck on the ATT worldcom splash screen.
I tried several things. First, I tried to boot into recovery mode (vol up+power, then release) stays on splash screen. However, in this mode, if I connect my phone via USB, an adb devices command shows as connected. From there I tried both an adb reboot recovery, and adb reboot download command. The adb reboot recovery reboots into the worldcom splash screen just like the key combo does. I can't recall what the download option did, though I think it worked.
Secondly, I realized I could reliably get the phone into download mode, so I decided I would try the download mode, and restore to stock. I found an ODIN on the seminal ODIN thread, downloaded it, and started it up. Put the phone into download mode (hold vol + and vol -, plug in the usb) and that worked fine, however, ODIN doesn't see my phone. I left the phone in this mode for a couple hours just to make sure, and tried disconnecting, and reconnecting, and initialized the procedure from the beginning several times -- no go.
So, I am stuck, and coming to the experts. Hopefully, someone has some good suggestions. I was unable to find someone in a similar predicament, so maybe I am SOL.
Thanks in advance for any help.
UPDATE:
I rebooted my laptop (windows XP) and when I plugged in my phone, it saw "new" hardware and the name of the hardware it sees is "gadget serial." This might explain, if it is not initializing the right drivers why ODIN can't see the phone. The only problem is I don't have any clue how to redirect it to see the right hardware now.
Success Update
After reading the seminal ODIN thread a bit more careful, I came across someone who had similar issues with the gadget serial device. Apparently the drivers I got (I think from the Samsung site) are not good enough to cover that aspect of use. I installed with the drivers from links on the ODIN post and my phone was recognized! As I type, I am installing back to stock.
Thanks everyone for their efforts, and I hope my experience could be useful.

Desk top or laptop, have you tried all the ports

I would test to see if adb recognizes your device first during normal operations. I'd that doesn't work, your usb port may not have enough power or you have a bad usb cable. I think adb can also restart right into download mode but check around first.

I tried two differing cables, both of good quality. One was the cable that came with the phone, the other was a mini-usb cable with a micro adapter. Neither worked. I can't do normal operations right now (that I know of), seeing how the phone is in a bad state.

Sorry, didn't read your first post close enough. I'm not sure what you can do, someone suggested the battery pull method in another thread, but that was just to get their phone in Download mode. It had nothing to do with ODIN after it was in download mode. Hopefully someone will have a suggestion for you. Good luck.

I'm having a similar issue except that odin sees the phone when booted into the rom, which I find odd.
Would you be so kind as to link the drivers?

[Q] UPDATED: ODIN wont recognize my phone with USB debugging on, but will without it

Alright, so I was having some problems with my cognition rom and decided go back to stock so I could flash the new cognition. I put my phone into download mode, and it took a few times for ODIN to see my phone. After I got ODIN to see my phone I tried to master clear, it did not work. I had to pull the battery out and try again. I rebooted my phone again, and many program errors came up. I shut off my phone, tried to get into download mode and it wouldn't let me using the volume down + up then insert USB with ODIN open.
Now to get into download mode I must hold buttons with battery out, put USB in, and put battery in and I get download mode instantly, but I cant get ODIN to recognize my phone at all anymore. I tried many different methods(odin open before DL mode, odin closed before download mode, etc). I looked through a few threads and couldnt find anything that would work. Also my window 7 64 now says it doesn't recognize the USB device when I plug it in. Whats going on with my phone?? Im getting very annoyed! Is there any way to go back to stock besides ODIN??? Any help is appreciated!!
***UPDATE***
Seems like I may have a 3 button combo lock, and no USB support of any kind(besides charging).

UPDATE: I used rom manager to flash over my old rom. My phone works again, but it wont go into download mode at all now. Only when I use the cognition menu to send it to download mode will it work. I still cant get ODIN to see my phone. I want to go back to stock still, but without ODIN working, can I?

under your captivate battery, there is a number like 1008, 1010, what is yours?

I've had the same trouble with download mode + odin on my Windows 7 64 bit pc too.
I have to have odin running, phone off with battery out, and usb cable in. I leave the battery out for about a 10 second count. Then put the battery in and hit all the buttons at the exact same time (power + volume up and down). The key here is that I only had to hit all three buttons momentarily to get it to go into download mode. I didn't have to hold them down for any length of time.
I easily spent 1 hour trying to get odin to work the last time I had to reflash to stock. Only because I forgot how hard it was three last time with my 64 bit machine.

1006
So should I just keep trying to get into ODIN by just fiddling around with it? Ive tried an XP machine and it wouldnt work either. Does booting into download mode from the cognition power menu any different than entering download mode the manual way? Every time I put the battery in with the USB it takes me to the battery charger screen. At first with that issue, putting in the battery last while holding down volume up and down, would put the phone into download mode(as opposed to the normal ways of getting into download mode). Now that wont even work at all.

first you can try the 3 button fix, just search the forum for that.
you may need to build a jig or buy one online just in case, it will get you into the download mode easily.

im having horrible trouble with adb cmd. I installed the samsung drivers, put my phone in usb debugging, did some tutorials on how to install sdk correctly, went to the correct file paths in cmd promt, and still cant access the adb shell. Any pointers on this?
Also, could I wipe all data off internal storage and use the "reinstall package" option in recovery mode to use rom manager update.zip to restore my rom from my sd card? Im not sure if thats possible. Im getting errors with my rom, and it feels slower since I just reinstalled over the top of my faulty rom.
Seems the only usb function I have right now is to charge it. Hmmm USB brick?

Any help out there???
3g stopped working on my phone when I woke up. I really need to get a fresh rom installed.

If I recall correctly, the path to where adb is had changed. Check all folders inside the sdk folder. to make my life easier, I put the sdk folder right into the root directory (c and renamed it sdk. Don't know if that well help or not...

I changed the folder to androidsdk from whatever it was.
bueller bueller bueller...anyone?

Well, if your phone is a rev 1006 you "should" have a problem like losing your button combo. I guess that could have happened but I doubt it, I've got a 1007 and never lost it.
So, as for ADB here's what I do. Take the android SDK folder you downloaded and look inside it. There is a folder called tools. I take the tools folder and copy it to the root of my C: drive. Make sure you have all the drivers loaded, speaking of which I would uninstall and reinstall the drivers. Sounds like they flaked out for some reason. Next open up a cmd window, Start > Run > CMD.
Then type,
cd /
cd tools
adb devices <<this shows if your phone is recognized. if it is...
adb reboot download
*or
adb reboot recovery
*or
adb shell
For what it's worth, I have been flashing my phone since I got it in July and the only time I Master Clear is when I have had a problem like a soft brick or something that I was suspicious about the data on my internal SD. Which, so far has been maybe 3 times. I don't think necessary to Master Clear every time you flash to stock.
Also, you shouldn't really have to the pop out the batter to do the download mode trick. I turn my phone off, hold both Vol up and down, then plug in USB and I'm in download mode.

Like I said, have you tried uninstalling the drivers from windows and reinstalling them? I am running Win 7 x64 and have had that happen. After i flash a rom or flash to stock sometimes windows doesn't recognize my phone at all. The first time I just used my laptop to flash but the second time I uninstalled the drivers and reinstalled. It's also important that you plug into the USB ports directly on the motherboard on the back of your PC. There are known problems when trying the front usb ports or through a hub.

Just curious, is it a Dell laptop? My Dell never recognizes my phone unless I power the laptop on with the phone/USB plugged in. If the laptop is on, and I plug phone in it never works, so I leave it plugged in and reboot and it works. It drives me crazy, but whatever it's my work PC.

It is a dell actually, but I just tried your method and it didnt work for me. Thanks for the input though!

Alright, I downloaded kies mini today and it actually installed some drivers correctly. I was able to pull up my internal drive on the computer, but it wouldn't read it. I was able to get ODIN to see my phone(first time in weeks), but it only shows up when my phone is NOT in debugging mode. So im assuming Master Clear will work now. I was using AIO captivate tool box, and my phone rebooted at the click of the button into download mode, but once again it wont see my phone in ODIN while in download mode. Im getting closer!
Why wont ODIN recognize my phone with USB debugging on? Any more suggestions on how to make this happen?

Captivate stuck on phone-!-computer screen, even with jig

So I was flashing a stock rom from Odin, and Odin froze, so I unplugged the phone and took out the battery. Now, when I try to get into download mode, all I get is a screen with a phone-!-computer. Even with a usb jig, it just goes to this screen. My captivate is also not recognized by the computer when I plug it in when its on the phone-!-computer screen.

But I don't see the Libusb tab in device manager when I plug my phone in.

When u initially installed the drivers for Heimdall, they only installed to the usb port that u were connected to. So u need to be plugged into that specific port and then u should see it in the Device Manager.
And u really don't need to uninstall the drivers that u need for Heimdall, as long as u installed them after u installed the drivers from Kies. See this post... http://forum.xda-developers.com/showpost.php?p=19998299&postcount=115
And if u have tried everything in the Stickied thread--Captivate Connection Issues and Download Mode Help to no avail, then ??

Yep I made a jig and it works but it doesn't go to the downloading screen with the shovel instead it just goes to the screen with the phone exclamation computer.

Then try this...may sound odd but anyway--just pull ur battery and leave it out for 5 minutes or so and then put it back in and try getting back into download mode and see what happens.
Btw, which stock odin were u trying that got u in this mess ?

The odin3 one click downloader. Yep I tried taking out the battery -- no go :/.

happened to my cappy yesterday. went through 7 hours to fix mine. had the same issue as yours. no download mode showing with any combo I try even recovery had 4 micro usb cables and still my pc is choosy. that screen is actually download mode. you just need the proper drivers for the pc to read it. I used the one from heimdall. tried for atleast 100x before my pc recognizes my cappy as gadget serial and then boom! after installing,uninstalling and reinstalling all is A-ok now. just try it and have faith on your cappy

What did you try before it was recognized? Did you just plug and replug the usb into the computer until it worked?

Mine did this before, when I accidently forgot to convert back to RFS before flashing back to stock, and I thought I was totally screwed. After this screen comes up the first time it will not go away, even if a download jig is used, until you get a good flash.
Try this:
Open your Odin, and have it ready with whatever you were trying to flash to begin with. Pull the battery on your phone, put your download jig in, and now put your battery in. It will still be the error screen that comes up. Pull your jig, and now plug your phone in. It should show on Odin now, and this flash should take correctly.

Also make sure the USB port you are using is a direct link to your board. I always use one of the original USB 2 ports on the back of my computer. Not using a USB hub either, but straight from the port to your phone.
