download mode -> unknown device - Galaxy S II Q&A, Help & Troubleshooting

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 .

USB debugging is off.
But as windows don't recognize the device, Odin can't detect it in download mode.
It's really weird

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] Any way to make the i9100 detected (usb)

Hi,
I have a 9100 that I try to make windows 7 x64 detect. I tried with the drivers and even with kies but the phone is simply not detected as if it was not connected with the usb cable. I played with debug on/off, and mount button but nothing worked.
I can charge the battery with the usb cable but cant xfer files, its only charging the pone, nothing else.
Any idea of what could be the problem ?
Install usb drivers via kies.
jje
Sent from my GT-I9100 using XDA Premium App
Hi,
I already done that, still no detection, its not even telling unknown device.
Just as any other windows hardware reboot phone reboot PC .
Boot phone set to USB mode in settings connect cable wait for windows to install drivers .
KIES tools Install driver .
That fails read all the other exact same posts for a solution .

It was the usb cable the problem. I changed it, now its working, thx for the help.

Close Kies from the system tray.
It is closed but again same problem
Are you using a HTC or Nokia usb cable?
1. use the original cable
2. kill all kies* pocesses in task manager
3. kill/shutdown all other htc/nokia/whatsoever software if present on your PC
4. try different USB plug (my friend had such problem with odin)
5. try different PC ;-)
should work...

Will not connect to PC

For some reason when i connect my GS2 to my computer (running xp) it wont give me the options to make it a mass storage device but when i use it on my laptop (running Windows 7) it works fine any ideas why and i ahve debugging on as well please help
you probably don't have the drivers installed on your PC - does the computer recognize the phone at all? if not, download samsung kies, and this should give you the appropriate drivers. alternatively, go on samsung's website and search for the appropriate drivers for the i777.
I'm having this similar issue but on Windows 7. I've already installed correct drivers and Samsung Kies. This issue began after I rooted my phone. I plug in my phone and my computer makes the device recognition sound. My phone is recognized in device manager as Samsung mobile usb composite device and my phone isn't in debug mode and doesn't give me the option for usb storage. I want to flash a rom into my phone but can't because I can't get into the internal sdcard. Any suggestions?
Try downloading pdanet on your computer. Then plug in your phone again. I had this problem and that fixed it for me.

Connection to PC doesn't work

Hi, I have big problem with my phone. First, it is not problem with MTP driver! My computer dont recognize connected phone. When I connect phone to PC, phone start recharging and Initializing MTP, but PC doesnt do *TDN* sound. When I connect flash disk trough USB OTG to my phone - it work. Other Samsung connect to my PC works good. I can't connect phone in "USB mass storage" - doesn't work. So I think, it is software problem in phone.
I tried:
Instaling a lot of roms (only in CWM recovery), pull up battery for a few minutes, format memories, restore my efs file ( I had copy efs file), manualy instal kernel, tried USB debugging ON/OFF, instal manualy MTP driver, uninstal/instal kies
Sorry for my english, isn't good
Reads like you do not have Kies installed and no USB drivers for the phone .
If that does not work clean USB port only connect to a mainboard USB port .
Fails = service centre .
Restore to stock first and reset custom rom counter or it will be no longer under warranty .

try with other pc to make sure is your phone problem..
or try samsung kies air if you using a laptop..
i install kies and get all the driver to enable me connect usb storage
First of all you MUST have samsung Kies just for the drivers of your phone.
Try install kies...
No need to install the complete package if you only need to use the phone as a mass storage device here is the link to download drivers directly

I'd question that this is a "direct" link. I've tried clicking just about every link on the page and all I can get it to download is some other bloatware/adware. There doesn't seem to be a working link to the Samsung USB driver on this page

Use the thread of SamHaLeKe: http://forum.xda-developers.com/showthread.php?t=961956
It provides a link to an USB driver installer (brown 'Download' text).

Lack of details posted so just a guess you have not installed Samsung USB drivers .
Sounds like a driver problem on your pc.
