Unknown Device

Hi to all i got a Samsung Captivate in Download Mode and I cannot do anything because my pc recognize it as unknown device. I installed and uninstalled drivers from forum and from samsung url but still the same problem. I downloaded AIO pack and installed the drivers but still no luck! I installed KIES but still nothing.... any ideas how to fix and flash my phone again to stock fw????
Thank You in advance

Have you tried multiple ports?
Delete drivers, dl again but don't install. When plug in message for unknown device pops up click it and select option to find drivers. Navigate to the file where dl is
May work

I have android sdk if is the same i dont know!

Sorry typo. Once again long shot but plug phone in click on the unkown device. Navigate to android sdk I think under extras then Google add one there is USB. Click on it then ok. See if it can find drivers that works
Sent from my Captivate using XDA Premium App

not compatible with x64 windows

Make sure you have the most recent USB drivers installed in your sdk. You may need.to enter sdk manager first. I may be wasting your time.

I gave a try to another pc still the same Unknown Device. Is there any way to bring it back to life??????does anybody knows??

Phone not recognized by ODIN

I am sorry to jump in but I am currently running the latest nightly and Ineed to flash bootloaders and start with Froyo again. But my computer is not detecting my phone. I have installed the Android SDK and installed the drivers for Nexus S but of no avail. i am stuck and would appreciate your help.
The funny thing is that I can use the phone as USB device but freaking ODIN is not detecting it. My windows does not has any unrecognised device. I have installed the Nexus S drivers as well. Is it a problem with ODIN or my phone or windows itself? I am running Windows 7 Enterprise 64 Bit edition.
I have tried;
Uninstalled Samsung Drivers / Restarted / Reinstalled
Swapped 2 different cords
Tried every available port on my PC
Restarted, pulled PC power cable, let it rest for a few seconds and plugged it back in
Uninstalled every USB Root Hub device and restarted so Windows could reinstall all of it
Tried Heimdall as well
I need my ODIN flashing back
Thanks in advance!

Look that Kies isn´t running in the Background.

It is not - I can confirm.

check with usb debugging activation on your phone!

Checked that too
Loosing hope on this -Am I going to be stuck with corrupt bootloaders and other issues?
Someone ... anyone?

Kies has an option to install the driver again check under tools then install driver maybe that will help

But Kies does not recognize the phone So it does not even try to install the drivers.
I am stuck. Without ODIN recognizing my phone, i can not flash anything on it or revert to stock. Would be great to know if there is anything I can do from Recovery Mode. The phone goes to Download mode as well but what's the use.

well this is a long shot but you could try and manually install it by going into where you installed kies in my case its C:\Program Files\Samsung\USB Drivers\24_flashusbdriver choose the X64 folder seeing as you are on a 64bit system and right click FlashUSB_x64.inf and install

Nope. It didnt help either.
F***! This is frustrating.

well you could always try it on a windows xp machine maybe try another usb cable you never know

i was having this problem too till i sent it back to samsung service centre where they changed the whole board.
my computer totally couldn't recognize my sms on either odin or usb. it won't restart when not connected to charging/power.
i've got a warranty claim and now it back and rooted with gingerbread 2.3.3 jvb install.
samsung service centre is the best. with service like that i'll stay with samsung all the way.
hope my experience help.

an obvious question, but since no one has asked it yet, are you in the download mode ? You have to be in download mode for Odin to detect.

That is not true. My Samsung Galaxy S is recognised by Odin even when on in normal mode.

Yeah, I ended up doing the exact same thing. Something must have gone weird, because the phone would still charge, but wouldn't be recognized by anything.

It may well be damage to usb on phone, remove the inner cover check for cracks in soldering, and check pounds aren't out of shape
If they are gently straighten with pin

Just Remove the battery and wait for 10 seconds......
insert battery and start in download mode...
tadaaaa.....it's done....

Did you install the drivers for Hemidall? After I did this my phone was not recognize by Odin... but I'm guessing If I roll back or update the drivers some how in Device Manager then Odin would be happy again.

[Q]Samsung Captivate bricked?

Recently, I was updating my new Captivate using Kies Mini and the update failed, I flashed a couple of ROMs using Odinoneclick and after a couple of tries, I ****ed up my phone, I got it to a point where it would go through a boot loop and eventually get to the GB rom I installed but even that barely worked. Now I finally got my phone into download mode (actually the screeen with the pic of the phone then the triangle then the computer) but my phone wont be detected by my laptop (as in no message pops up as I plug it in) so I can't do an Odin Oneclick to stock 2.1. What can I do to fix this?
Thanks in advance

If you installed Heimdall, Odin won't work on the same USB port. I assume you already tried deleting and reinstalling your drivers?
The only thing that worked for me when that happened before was using a different USB port and finaly flashed KK4 through Odin. If you have access to another pc, that would probably fix your connection problem as well (as long as that pc has the needed drivers).

Well then you don't have that many options left. If I were you, I'd keep trying to delete/reinstall drivers (of course, pc restart), swapping USB port and try both Odin and Heimdall (remember that Odin won't work on the same USB port as Heimwall installed his drivers on). Perhaps, using a different usb cable would work too. After that, the only thing I can think would be to use a different pc.
Sometime it's a mix of those things that will make it work, our cappys are quite capricious lol.

I made a 300k ohm jig and it worked but now when I try it, I think it puts the phone in Firmware error mode or whatever its called, or am I just doing it wrong

U r doing it right. That can be an alternate download mode.
U just got to get Odin or Heimdall to recoqnize it now, so u can flash a Stock firmware.
Have u tried using a different micro usb/usb cable to get Odin to see ur phone ? And usb port in the back of the pc, not a hub ?

It's a laptop and I've tried every USB port, and Idh any other cables

Ok...but if u can get ur hands on another cable, it would definately be worth a try, especially if all else is not working. I have personally see it and read it over and over that a different cable does the trick.

Is it most likely the cable?

Idk about most likely...but like i said, if u have exhausted all other means, then it is worth trying.
I personally found several at a Dollar Tree store over a year and a half ago. I use one of them all of the time instead of the one that came with the phone, because that samsung cable just stopped workin for me just outta the blue. It happens. One day a trustworthy cable and then one day not. And of all things, the cable i got for a $1 has worked great. :thumbup:

Problen with Odin. First time root.

I've tried everything, I just can't get odin to recognize my phone. I use a Samsung Galaxy S GT-I9000 and the odin version is Odin3 v3.07, although I have tried using an older version of odin.
My phone gets detected normally (when not in download mode), and even in download mode the computer does make the sound indicating that it is connected.
This time, I opened odin without putting my phone in download mode and it showed a blue box, indicating that it detected my device, however I think being in download mode is a necessity for rooting. Help me out!
Oh and if its important, I use windows 8, I don't have samsung kies installed, I have the stock USB cable and I have tried it out without another cable.
AH! The shame! My first post and there is a typo in the title! T-T

Hey,
Have you tried manually installing the drivers using this?
http://forum.xda-developers.com/showthread.php?t=2038555
The Samsung USB drivers (which lets the computer properly recognise the phone) apparently don't play too nicely with Windows 8.
Try install that and see if Odin recognises your phone

just flash this in stock recovery you only need odin for custom recovery

[Q] USB mode not working

Hey, been using this site for couple weeks now and loving all the roms you guys make but i'm having trouble getting my s5830 to connect through usb mode.
I'm running slimrom V3 and windows xp home edition, i've installed kies and all the drivers but when i open kies it just says connecting then gives an i/o error when i click on the new drive in my computer. Any ideas how i can get it working?

Kies won't detect your phone after root and after installing a custom rom. What happens when you plug you phone into the computer? Does your phone say in the notification bar USB connected

Oh ok thanks, didn't know that about kies.
Yea it shows in the notification bar, i can turn usb mode on an off but when i click the new drive in my computer it either crashes or gives an i/o error.

The drivers should be set up already if not try and reinstall them again you might aswel delete Kies unless you have a stock phone, what are you trying to do?
