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.
Hello,
My Samsung Galaxy S is listed as Unknown Device.
It started after an update to 2.2 via Kies and i did that with the regedit exploration. That was the 2.2 beta and then i updated it again with the official release this time also with the regedit exploit. I have formated the internal SD (i cant dismount it cause im on froyo i guess? atleast there is no option about it). Factory reset and so on.
Reinstalled kies 5 times, installed USB drivers again and again. I have tried it on different platforms with both XP (32-bit), Vista (32-bit) and Slackware Linux (32-bit). The computors just cant find drivers for the device.
I have tried all the different usb options in the phone settings nothing happends. I think i have tried everything that can be found here and on google...
The phone is Rooted and im now on PDA: I9000XWJP6, PHONE: I9000XXJPM, CSC: I9000XEEJP4.
Build Info: 2010. 10.
I believe the main thing here is that i dont even get the MTP application in the phone to recognize that a USB connection have been initialized. Nothing happend in the phone when i connect the USB no MTP screen or anything, just chargeing. I have tried 2 diffrent usb cords both that worked before so its not that.. The computor just says unknown device and Kies dont notice anything at all.
I have tried installing another firmware with Odin in Download mode and stil unknown device.
So i believe the phone have, in some way lost its internal usb drivers? I have also noticed that the battery "100% charged" icon does not disapear after i disconnect the usb or the charger. Also sometimes the icon continues to charge after i disconnect. Sometimes when i turn the phone of it starts by itself after like 2 min.
Anyways! What i was wondering is if there is a way to install an official firmware via update.zip volume-up+home+power?
When i try to install a customized rom with update.zip it says:
E:signature verification failed Installation aborted.
Cause of 3e bootloader? But i think its best to maby have a good stable firmware before i go customized?
So any help would be appreciated!!! heeeeeeeelp.....
Try installing theses drivers x64 x86 depending on what operating system you're on.
If that doesn't work try going into download mode and connect with odin. With the recovery problem you need to flash 2e recovery
You can also try and download and flash the latest version firmware to your phone and see if that helps.
Good luck and tell me how it goes

Hi m8!
Thx for the reply!
I have allready tried installing those drivers doesnt work for me.
I have tried Download mode with Odin to, it still says Unknown Device in Windows (i have Vista 32-bits, but tried it on XP and Linux to).
So anything that has to do with a USB-connection seems impossible at the moment...
The phone dont start the MTP application at all and windows dont install the drivers, it just says unknown device when trying to install.
I just unistalled Kies and removed everything from regedit with "kies" in it and then rebooted and downloaded a new fresh Kies file. Installed it and rebooted again while i wiped the phone, formated the SD and did a factory reset.. still "Unknown Device" :[
The problem seems to be the software in the phone.. so my question is: Is there is anyway to update or flash the firmware in the phone without any USB connection?
Is there maby any way to get 2e recovery mode without usb connection?

There is an app in the Android Development section here that allows you to flash a kernel within Android. Never tried it myself but I believe it is now stable and you could use it to flash CF-Root internally
EDIT: Here you go...

Have you tried recovery mode? Big yellow triangle with Android man holding shovel. Then connect to PC with Kies running and click on firmware update button.

But it seems that i dont have root access anymore, so cant use that app either :/ i think im a hopeless case.. :[

Yes man.. i get the same thing with the Yellow friend that says "Do not turn of target!!!"..
"One of the USB devices attached to this computor has malfunctioned. And Windows does not recognize it."
and also
"Unknown Device Installed
The software for this device has been successfully installed.
Unknown device - - Ready to use"
Are you connecting through a hub or direct to the back port of the PC. A hub will cause problems. If direct then try this.. Plug in and wait till you get the unrecognised device info. go into device manager, identify the device it will either say Samsung or unknown device. right click and remove device say yes if it asks if you want to delete the driver. now restart the pc after unplugging the usb then after it has fully restarted and connected to the net plug it back in again. Hopefully it will look on the net for the driver and install the correct one.

Yep tried that to.. i have even tried it on 3 diffrent computers 2 of them in all usb ports.. and everything els works that was connected in those ports.
I dont think its the software in the computer that is the problem.. :/
I believe there is some internal (in the phone) usb firmware problem, if thats possible?
i have exactly the same problem my usb by giving uknown device (i used it at 3 computer with kies software) it seems usb not working anywhere.
I believe our only solution is to find a way to install e2 recovery via the phone.
I have this problem also.
My SGS is rooted.
I tried everything. Googled many hour.
I din't know what more to do.
I have "Android system recovery <2e>" Is this an advantage?
I turned the phone in to my provider. this message is what i got from the repairservice.
Repair Details: The phone's charge connector is moisture/water -damaged, can not be repaired. returned without action.
WTF?!! i have been really careful with the phone. The only thing i can think of is that it has been really cold where i live (Sweden) and i had it in my pocket.. but i mean cmon! it goto withstand that!
I guess i have to wait for samsung to make it possible to update firmware via Wifi.

With Recovery 2e i think it can be possible to update your phones firmware with the update.zip file but i think you need to have your phone rooted.

I think so. I have my phone rooted and also ROM Flash Manager installed. The issue now is to find an european stock image to flash compatible with ROM Flash Manager
I looked for the stock firmware image (my phone has JF3) but can't find where.
Anyone?
I don't want to flash a cooked image just in case I have to ship the phone to the repair service.
Hello, I have exactly the same problem.
My SGS is unrooted, due to warranty, and alway keep it with maximum care (it is not a free phone...).
Symptoms are the same:
-It started after an update to 2.2 via Kies
-Absolutely unrecognized by windows (xp32 and win764) anymore
-battery "100% charged" icon does not disappear after i disconnect the usb or the charger
-turning the phone off it starts by itself after like 2 min.
More: incredible but sometimes when connected to car charger, I have the message "usb connected".
Already tried all possible (unrooted) tricks.
I believe usb internal drivers (if any) are corrupted (maybe by moisture?), how to reinstall them?
Maybe usb connector damaged; I have moved a little bit with a scrwdrvr the usb connector plate and clean with air and a thin blade but no result.
I will bring to service, as warranty is still valid, but surely they will discard me (I am optimist)
If there is any solution, please post it.
Hello,
Same here, can't connect phone to pc, mtp dont start on phone after connect it on pc !
Anyone know how flashback stock rom if its possible ?
Hi someone have a stock firmware for flash it in to recovery ?
I think i will try send the phone to samsung after reflashing for see what the guys from samsupport says about this !
Yes, if a part of firmware has been corrupted (with usb info for pc recognition) maybe the solution is to reinstall entire rom.
How to find a stock rom?
How to reinstall rom from SD card in a non rooted phone with no usb connection?
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..

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 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.
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.

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

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.
Okay.
I bought a Samsung Captivate from a company on Amazon a few weeks ago, and it started having the problem with the speaker cutting out. I took it apart to try the two fixed I'd googled - loosening the speaker screw and reseating the speaker ribbon - and neither worked, and now the speaker is completely dead. That isn't my biggest problem, though.
Somehow in the process of the above, I did something that made it so that the phone will only boot into download mode. I can hold down the power and volume buttons and get it to reboot, but it only reboots into download mode again, and won't recognize in windows via the USB cable. It did recognize once, and I used Odin3 to get it back to a factory reset image (it was running stock firmware, but I'd rooted it to remove the AT&T apps) thinking in vain that it might help, but it still only boots into download mode.
But there's the weird thing: It won't power off in download mode unless I pull the battery out, but if I put it back in then plug in the USB cable while holding both volume buttons, it boots right into android, no problem. Everything's fine except the speaker still doesn't work, it doesn't show to be charging while plugged into the USB cable, and still won't recognize the USB in Windows. But if I turn the phone off and back on, I'm back in non-recognizing download mode again.
Everything otherwise works fine once I get it into android, I can even tell it to erase all settings and factory reset, and it reboots itself, re-flashes to stock, and works fine until I power off and back on, then back to download mode.
So I guess the question is oh god what have I done?
Freud,
I too am having this issue with my roommate's phone. The only way I can get it to boot is if I perform a restore using a Odin3 image. However once it's turned off it only boots into download mode. I nor the roommate have opened the phone. It just one day decided to keep booting into download mode.
Any asistance in this matter would be appreciated! Thank you.

Okay.
I bought a Samsung Captivate from a company on Amazon a few weeks ago, and it started having the problem with the speaker cutting out. I took it apart to try the two fixed I'd googled - loosening the speaker screw and reseating the speaker ribbon - and neither worked, and now the speaker is completely dead. That isn't my biggest problem, though.

I can only offer a solution to the windows connection issue, once the phone is connected to pc, go into device manager and uninstall drivers for whatever it sees, unplug phone then plug back in and windows should reinstall drivers. Worked for me, odin wouldnt see phone . GL
This will solve your speaker issue

And this should solve your download mode issue

I'm having a similar issue where my PC does not recognize the device. Right now I have no ROM installed, I have Devil Recovery, and I can only boot into recovery and Download Mode. However 2 different PC's will not recognize the phone. I've tried multiple cables and one PC was Windows 8, one was Windows Vista. Both had the most recent drivers installed. Nothing works....any clue? I can't mount the /sdcard or USB Storage while in recovery because the PC doesn't pick up the phone. The internal storage doesn't have a ROM or kernel to flash on it neither so I cannot flash anything. I have a captivate that has Devil Recovery and can boot into download mode but will computers will not recognize the device, drivers installed or not.

Have you tried to uninstall the current drivers, reboot pc and reinstall them?
Also, it could be devil kernel that is faulty. If Odin can recognize the phone, you could flash a different kernel. Or even flash stock KK4, then corn kernel and finally, the ROM you wanna flash through recovery.
I just cannot get the PC to recognize the phone at all, even in download mode. I've tried 2 pc's and multiple USB cables, samsung, non-samsung, motorola, universial. Nothing, just says USB cannot recognize this device. Reinstalled drivers on 2 pc's and rebooted several times. I am lost, I know I'm not bricked because I can access download mode and recovery. I do not have a ROM on my internal card so I can't flash a ROM and can't mount my phone to my PC. No clue what to do.

I just need my PC to recognize my device and I'd be good, odin would then recognize my device in download mode and I could flash a different kernel or rom.
Try cleaning out the micro usb port of ur phone. Maybe the contacts are not making good contact.

Any recomendations for what to use to clean it out? I have q-tips, any special solution to use or just the q-tip?
Rubbing alcohol should do.

Still no luck...I got my PC at work to recognize the phone ONCE. It went through and recognized it like it normally would, however it wouldn't recognize it again. I've been trying on my PC at home all last night and all morning and still no go. It won't recognize it. Now one thing I thought about is that I am on Windows 8. The PC at work that recognized it was Windows Vista. I don't know if that has anything to do with it. I wouldn't care so much if I didn't just sell it for $150 I just wanted to give the person a more updated ROM and ended up screwing something up when flashing the ROM.

Ok so I know you've uninstalled and reinstalled drivers several time. But what drivers are you using and when you plug the phone into your pc what is it showing as in the device manager?
They may be exactly what you are using but I added some drivers to this post you might want to try. Just unzip then through device manager update the drivers for your device manually and point it to that folder.
I added these drivers because I'm on Win8 as well and I noticed when I was in recovery that my phone wasn't showing up correctly in the device manager. After installing these drivers it was.
Thanks I'll try that when I get home, I am using the most recent drivers on the Samsung website for the Captivate.
So I got it to boot and be recognized by my computer and I used a 1 click method with CWM and it passed so the Odin flash. So no I basically have a on rooted captivate running 2.5 gingerbread and it is totally sellablebel now. I have no idea what caused my computer to recognize it I didn't even try your drivers yet, but thanks for trying to help.
