[Q] Computer won't recognize download mode, help?

Does anyone know why a win xp computer would recognize the debugging mode, I'm rooted and the one click root worked fine, but not recognize my phone when in download mode? I have the drivers installed and java sdk installed. Every time I go to download mode and plug in I get a pop up (on computer) that my device is malfunctioning and the device manager says unknown device.
I know it's not the cables because I used my brothers laptop to flash eb13 from the froyo install tool before installing syndicate. But three computers including mine have failed with this same message.
I'm confused why this one lowly laptop that is nothing special worked fine and my computer along with the other 2 give me this "usb device malfunction try connecting device again, if fails replace device". Not an exact quote.
It's a long drive to my brothers, and I would like to use odin with out having to wait a couple days til I can drive out their. It's been putting a cramp in my rom flashing mojo. Any help would be greatly appreciated. I have done a bit of searching and haven't found a solution yet, among,
Trying different usb cables
Every usb port tried
Have it in download mode and plugged in while booting computer, (doesn't
Give message just doesn't connect. Then unplug replug gives message.)
Every combo of debug, unknown source on/off
Java sdk installed

Try downloading the XP drivers from Samsung and installing them fresh. I had a similiar problem. My computer took almost 10 minutes to connect all drivers the first time with new drivers. Then Odin worked fine after that.
BONSAI 4 and loving it!

"USB Device not recognized" - Tried everything I could think of / find

I've recently run into a problem with my phone being recognized by my computer... basically it just doesn't work anymore. This happened after upgrading from Midnight ROM 5.3 to ACS Frozen 1.2. At this point, when I plug my phone into the computer, it only charges and does not enter into usb connected mode. On the computer I get a pop-up message saying that the USB Device is not recognized. After searching through these forums and others, I have tried uninstalling / reinstalling drivers, installing PDANet, switching USB ports, and Switching USB cables... All multiple times. The best I've gotten out of the process is immediately after certain tries, I am able to get the usb mode activated, but only once. When I try to boot the phone into download mode because I'm trying to upgrade to EF02, it is no longer recognized, and then when I do a regular boot, it is still no longer recognized.
Any help would be appreciated.
Thanks,
Greg

I've also toggled USB debugging multiple times...

Which OS is your PC running?

Try downloading the android sdk and updating all its files and repo's? I had to do that for my w7 x64 pc to see my epic
Posted by some phone named the Epic.

Your drivers crapped out or your cable is flaky. Try a different cable. Also turn on USB debugging and go into Device Manager in system in control panel. Go to the unknown USB device (may say Samsung Android) and hit update driver and let it search Windows update for drivers, will take a long time for all the drivers. Then reboot and should work.

Are you using the cable that came with your phone? Mine stopped working and I had to buy a new cord off amazon.

Win 7 x64 is the OS...
I've found a temporary workaround by pulling the battery, plugging the device into the usb, starting it into download mode, and then replacing the battery, but thats not really practical for storage purposes, only for the one time install of EF02. I have used 4 different cables and reinstalled the drivers multiple times. I am going to try reinstalling the sdk and see if that helps, as well as searching drivers using Win 7 Device Manager.

[HELP] Epic 4g win7 64 odin [HELP]

So I have done something to my epic, I don't know if it would count as bricked soft bricked or whatever but when I turn it on it bootloops on samsung logo but I can still enter download mode, So I figured I would flash a stock rom with odin and start over.
I went to this thread
http://forum.xda-developers.com/showthread.php?t=1052813
downloaded necessary drivers
installed and tried to connect to odin
I've tried every combination of powering the phone with the computer, then putting in download mode
I've tried powering on with battery booting into download mode opening odin selecting pit and tar and then pluging it in and nothing.
when the pc does recognize the phone it says device not recognized or device malfunctioned.
I saw a post somewhere with someone saying I needed to "advanced install" the drivers. So whatever that means I tried to uninstall the device from device manager while plugged in in download mode and updating the driver to the 64bit samsung usb driver and it says "unknown device already has best driver installed"
the computer I'm using is an HP DM1-4010us not that I think it would matter.
If anyone has anymore suggestions, or can suggest a method or pattern of step by step what I need to do
maybe install the drivers in a different compatibility mode?
what about odin compatibility?
System UAC is turned off and firewall is off too just in case it may be blocking odin from communicating with comm ports so I know that can't be the issue.
Thanks for listening to my overly detailed and confused ramblings and thanks in advance for any advice or help offered.

Try a different USB port and cable the stock cable sucks azz try a blackberry cable.

Have you tried a different usb port?
I have always used the cable that came with my epic, are you using it?
I'd at least open odin, put your phone into download mode and then connect it to the PC and see if with the stock cable it is recognized. That will tell you perhaps the cable you're using isn't connecting right for odin's use.
do you have any other cell phone drivers on your PC? I've seen where they conflict. Remove all cells phone drivers, reboot, install the epic drivers for win7 64bit
EDIT: damn i type slow. someone got itn there already

Heimdall fails to install drivers or detect the device, does this with AND without the samsung 64bit drivers installed.

Try downloading kies air to get drivers.

Make sure you downloaded the drivers named "Samsung_Mobile_Drivers_V1.3.8.." if not then that's the problem, if you need it I can email you the the file. Try all the usb cables in your house and all the computers as well, and take out sd card, I've also had this odin problem and I'm also sure it's your drivers since there are like 10 samsung drivers floating around lol.
Edit: nvm I downloaded the drivers from the thread you linked and they are correct.. try different cables, no battery no sd card, and different computers

[Solved] [Q] I9250M not recognized by fastboot or adb.

Hi guys,
I'm using the I9250M for work, and attempted an update through Kies with usb debugging off. The update failed, and now I'm left with a yellow triangle with an exclamation mark.
I've tried holding both volume up/down buttons and power, but cannot get into download mode or any other mode. I've taken out the battery and held the power button down for 30 seconds, then replaced the battery, but still nothing.
It seems that there is no communication between the pc and phone regardless of the drivers being found and installed.
Things I've tried:
Connecting with Kies - Installed drivers through device manager using windows update. Kies is stuck on "Connecting". Only the OMAP4440 driver could not be found so had to install the OMAP4460 driver.
OMAPFlash - this seems to work ok but not sure what to do when it says "Press any key". There is no mode change after flashing (I still have the yellow triangle).
After looking through the stickies and other tutorials I've tried using the Galaxy Nexus toolkit, PDANet, Odin and WugFresh tools, but they all seem to need usb debugging on, which I can't get to.
From past experience (with windows mobile), I've usually been able to unbrick a phone if it is recognized by a windows pc, so even though this is an android phone, I'm hoping that I can do something to get this phone back in working order.
Further info: The two Samsung usb drivers installed on my windows 7 64 bit machine are modem and CDC. I've also tried using a couple of the adb interface drivers in device manager with no luck.
If I can somehow get to the download mode, that would be half the battle won.
Any suggestions.
Cheers!

You need Odin.
Beamed from my Grouper

Thanks for your reply Mach3.2.
As mentioned in my first post, I tried Odin 1.85 and 1.87 already but the phone wasn't recognized. So, I decided to try Odin 1.87 on XP, and hey presto, the phone was recognized.
So that was my problem, I needed to use Odin on Windows XP. Hope this helps someone.
Thanks!!!

Soft Brick. PC won't recognize my Note 2 in Odin Download mode. Tried everything.

Hopefully I can get some help here. I've tried everything. Specs: Galaxy Note 2 SPH-L900 Sprint phone
Flashed CF auto root a while back and a custom ROM. That's it. And even when the phone was working, the drivers just don't work right with this particular phone. So.... before you ask, here's what I know. I've tried everything listed here:
** IMPORTANT NOTE: KIES DOESN'T READ DEVICE AFTER FLASHING CUSTOM FIRMWARE VIA ODIN **
1. Use Windows 7, Install all windows updates.
2. Unplug all usb devices except mouse and keyboard, unplug device, Uninstall drivers, restart computer.
3. Install the correct drivers for the device from Samsung site "USB drivers for mobile phones v1.5.45.00"
4. (Device still unplugged) Open ODIN V3 1.85, restart into download mode (power, home, volume down, then volume up), PLUG IN. Still not recognizing, Take out battery, put in battery. Nothing? take out battery still plugged in, restart in download mode, put in battery. Tried everything.
5. Use a USB 2.0 port (not 3.0), try different ports in case a port is defective.
6. Change the cable to official samsung cable, try different cables in case one is inferior quality or defective,
7. Unplug device, Uninstall drivers, restart computer, install Kies or Kies 3 - kies NOT detecting phone at all. Keep connected. Under Tools, Reinstall Device Driver.
IMPORTANT NOTE: KIES DOES NOT RECOGNIZE DEVICES WITH CUSTOM FIRMWARE AFTER FLASHING!!!
8. REPEAT STEP 2, then run ODIN V3 1.85 with admin rights, PLUG IT IN, if it doesn't read it,
leave it plugged in, unplug the battery, put the battery back in, ODIN should read it. Try different versions of Odin to make sure.
9. Download Root Genius and see if that works.
I've also considered this, but my computer sees that I'm plugging something in, but it won't load the correct drivers.
I manually install and find the correct drivers in DEVICE MANAGER and it still malfunctions.
**10. Hardware: USB Connection on phone could be faulty. Try fixing/replacing the usb terminal on phone.
My phone went into a soft brick because superSU play store app kept telling me to update the SuperSU binary and when I clicked "update superSU binary" in the app, BOOT LOOP CITTY and i haven't fixed it since.
I'm so tired. Been at this for 3-4 days. Can I please get some help? Thanks
