download mode -> unknown device

Hello everyone,
I've searched for a solution over the forum but I didn't find any solution..
So my problem is that I can't use Odin because windows doesn't recognize my phone on Download mode.
I have the drivers installed, Kies and windows recognize my GS2 without problems.
I've tried with different cable, different USB port, uninstall/reinstall drivers many times, from Kies or from samsung web site.
I just have no idea why in download mode windows doesn't use the installed drivers..
Help?
Thanks!
Did you try in a different PC?
I am sure driver is the only cause. Perhaps you can try following. Install Kies, then connect phone once and check if Kies detects your phone
Which version of Windows are you using? I am using Windows 7 and its working fine. I did root yesterday and Windows detected drivers and also it had to download from net for some reason. In the end it did work
USB cable to main board connection .
Reboot phone turn USB debugging off .
Set USB to Mass storage mode .
Connect cable and let Windows find USB drivers .

Did you terminate every Kies process before opening Odin?
Hello,
Thanks for the answers.
I'm running on windows 7 64. But it didn't try on another pc.
Windows does install drivers and recognize my phone in USB to Mass storage mode.
But still not recognize it in download mode and yes I've terminated every Kies process.
I know that in Download mode windows install some new/different (?) drivers. When I'm on download mode, windows fails to install driver as it's an "unknown device". Is there a way to install those drivers manually?
Hello,
Un-install Kies, reboot system, reinstall kies.
Still not work. After reboot and reinstalling Kies my phone was recognized, but in download mode there is still nothing.
If windows has USB drivers then download mode works .
Is USB debugging turned off .
Reboot phone
Enter download mode follow instructions on download mode screen .
Open Odin select files to flash
Connect Samsung USB cable to mainboard port .
Hit start on Odin .
jje
USB debugging is off.
But as windows don't recognize the device, Odin can't detect it in download mode.
It's really weird

Post the steps you are taking from the very beginning .

Ok, I manage to get this working.
I did this:
-I have unplugged all the USB on my motherboard, I've uninstalled all the "Universal Serial Bus controllers" (to acces type devmgmt.msc in windows start menu)
-Turn off the PC and unplugged the power supply. Waiting like 3 minutes.
-Replug the power supply and boot.
-Replug all my USB, windows reinstalling everything.
-Plug my phone in download mode and windows finally installed the drivers and Odin detect it !
So if someone have a unknown device issue with a code 43, please try this.
Thanks for your time and answers.
Disabling the "unknown device" and then disconnecting and reconnecting my phone worked for me.
Run Kies as Administrator, Install Drivers
This is what worked for me. Kies said the Drivers were installed without Administrator but nothing worked

[Q] HELP! SIII At&t NOT connecting to Win 7 x64

Hi Guys,
Recently got the AT&T edition of the S3 and i'm having the hardest time connecting it to my Win7 x64 laptop. It just wont recognize it and always comes up as a "USB Device not recognized"
Using Kies I have tried a number of things..
1)Rebooting phone
2)USB Debugging on/off
3)Reinstalling drivers "SAMSUNG_USB_Driver_1.5.4.0.exe and/or ATT_I747_GSIII_Samsung_USB_Driver_v1_4_6_0.exe"
4) Clear Cache from Phone
5) Restart pc x numerous times
Every time I connect the USB cable on the phone it says "Connected as a media device" I checked PhoneUtil via *#7284# and under Qualcomm USB settings it has MTP checked, should it say something else?
I have no idea what to do next but to maybe mount a Windows 7 x32bit VirtualMachine and try my luck there... Any help would be great!
Also, under "C:\Program Files (x86)\Samsung\USB Drivers\" which is the name of the exact *.inf file for the driver?
Hi there,
I have the same problem, but on the UK SGS3.
What ALL have you done to your phone since you got it?
Rooted, custom rom, backed up efs etc ?

[Q] Samsung Grand-Doesnt get recognised on PC (Updated Drivers installed)

Hi,
I use Windows XP Prof SP2 on my HP 520 laptop and am trying to connect my Samsung Grand phone as Mass Storage.... unsuccessful!!! :crying:
When I connect my Grand to my laptop using USB cable, my phone says "Connected as media device", and sometimes the right bottom corner notification on my laptop recognises my device and flashes I9082 and then says "a problem occured during installation of your hardware", and sometimes my laptop doesnt recognise (it does nothing).
When I check Device manager, it has a yellow exclamation next to the Samsung Mobile MTP device driver (screenshot attached)...
I have uninstalled and reinstalled Samsung USB Drivers for Grand on my laptop & restarted after driver installation. I also uninstalled and reinstalled Kies latest version, several times. Have tried going to Device Manager and updating the driver. Just says that there was no better match found than the software already installed (Screenshot attached)
Samsung Kies recognises my device as GT-I9082 but just says "Connecting" and stays that way for hours (Screenshot attached)... I m looking at connecting my android device as mass storage (I somehow dont find Samsung Kies comfortable enough).
Please let me know the way forward.

This device cannot start (Code 10) - PC Android USB error?

I am using Windows 7 64 Bit..
I have followed the correct procedure for installing the USB vcom mtek drivers and still I get this error.. It says : This device cannot start. (Code 10)
I have tried restarting the computer with the phone turned on and off, I've also tried changing the USB connection settings on the phone to"media device (MTP).. Also tried the "USB Storage" option.
No joy.. Any clues as to how to install this drive without the code 10 error????
I want to flash my phone but I can't because the Smart Phone Flash Tool cannot connect to my device in the way it want's to.
I can navigate the files of my phone via the PC though..
When I changed my USB connection settings type to 'Media Device (MTP) I could see 'Leagoo Lead_5' in my Portable Devices section of my Device Manager on my PC..
Does anybody use these forums?
What make and model of phone is it?
with the make and model we can help more by finding better drivers
but another thing to try right now, is try plug it into a different USB port(one at the back thats part of the motherboard rather than a expansion front style port)

[Help] PC unable to connect to Honor 9

Hi,
After the most recent update (OTA), when I connect my phone to my PC, regardless of what mode I have the USB set for on the phone, I can no longer connect
to my phone.
It worked flawlessly before.
The Huawei HiSuite also cannot connect (although I don't norm ally use that anyway).
I have tried reinstalling ADB and also HiSuite to no avail.
One thing I do notice is that there was a HDB driver missing. When I rebooted my PC it has now changed to 'USB Composite device' but shows the error
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
{Bad Image}
%hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0x
I've tried to automatically install a driver, again no joy. (Because the device is not recognised, it just says it could not a find a suitable driver).
If I uninstall the device and then plug my phone back in we then start with the HDB device (for which there is no driver according to MS), which upon reboot becomes the 'USB Composite device' again.
So, anyone know how I can fix this? I'd like access to my phone through my PC if possible.
TIA (Thanks in Advance)
I know it's obvious, but have you tried a different usb port.

Yes. Front and back of PC as well through a hub.
It makes a sound like it connects, then I get a popup on my phone "Charge only / Transfer files / Transfer photos" and regardless of which one I select, it then disconnects.
Somewhat annoying. It worked okay before latest update.
I've even reinstalled ADB, even though I'm fairly certain this has nothing to do with it.
Thanks for your reply anyway!
[Solved]
I managed to solve this by plugging in my Honor 9. On the device manager page in Windows take a look at the 'USB Composite Device' item and selecting with an exclamation mark against it and right click it and select"Uninstall device" from the menu. When it asks to remove the driver, select yes. Unplug your phone. Reboot your PC. Upon plugging your phone back in, your device will be re-detected and Windows will install the driver correctly.
