Drivers wont install - Galaxy S II Q&A, Help & Troubleshooting

My phone can't get detected on Computer. I have been trying everything and it keeps telling me USB DEVICE NOT RECOGNIZED....please help.

Have you installed Samsung Kies? I'm not sure if it's needed just to use the storage on the phone, but if you're trying to use Odin it installs the drivers required for that.
Also try going to Settings>Applications>Development, untick or tick USB Debugging, if it still doesn't work do the oppisite and try again (sometimes I have to disable then re-enable to get it working).

u didn't mention if u have win 7 or not
YES in order to get detected by KIES u have to TURN OFF USB Debugging
but in case if it still not get recognized ....then at the time of plugging .....when windows tries to auto install drivers .....u just have to open the auto installation window and set windows to search for its own update for related drivers ..... it will install samsung drivers itself

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

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

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.

Install Samsung Kies to be able your PC to detect your phone via Odin
also check the debugging mode in the developer options

I have uninstalled the older Kies, re installed the latest.
I have installed the lastest odin.
Have tried to link up with and without debugging, odin still does not see phone when in recovery mode.
Only time odin see the phone when phone is in normal mode.
Starting to get annoyed now lol, i cant cut my sim to fit phone, untill this is done
I cant see my s2 on odin either, what am i doing wrong ????
1. Reboot PC
2. Ensure KIES is not running and kill any KIES processes in PC task manager.
3. Download mode
4. Connect USB directly to PC port (no hub)
5. Wait for any drivers to instal or load on PC
6. Start Odin in administrator mode
If still no good;
a) Different USB cable
b) Different PC USB port and wait for drivers

Thanks . Seems that I had been pressing volume up not down.
I have another question . I used chainfire Rom to debrand the phone but keis does not recognize . How can I solve this . Could it be because the phone is rooted ?
i am having this problem at the mo, I have tried all of the above, apart from a different pc.
oden worked fine with my galaxy s2
is there any more updates on how to sort this out please?
thanks

I know this is a 7 day old thread, but I feel for you having been in the same situation. Firstly, have you installed the Android SDK? If not then I advise you to do so. Do a search on how to install the SDK. There maybe smaller downloads available with a package of the binaries you need to do some testing i.e. adb. The instructions will elaborate about how to set up your Environment settings in Windows. Essentially ADB needs to be called from within any part of your Windows system....or else you will have to cd to its location each and every time you want to do something like this. So once you have done that, open command prompt and type adb and see what comes up? If it says bad command or file name it means your environment settings for the ASK are incorrect, if it displays the adb help text in command prompt you are ready to proceed.
When you plug your device in (not in DL or recovery modes) is it detected by the PC? If so then your drivers are probably fine. If not then it maybe 1 of 2 things? 1 the device is detected but the MTP drivers have not been loaded or 2. No detection what so ever and all drivers need to be installed.
To determine how to proceed you will need to do a bit of investigating.
Note the USB drivers are included as part of the Android SDK.
Check in Device manager inside of Windows to see if anything is detected when you plug it in. If so but it has a yellow exclamation ! then it would indicate you need to update your drivers (but not always?). From here you can test to see if the phone is detected and you only need MTP drivers.
If not then I would suggest uninstalling Keis all together and downloading and installing the Samsung USB drivers separately. Install the drivers. Plug in the phone. If it is not detected straight away, then reboot the PC then plug the phone into a different USB port. From here you can determine how to proceed by using adb.
plug your phone in via USB and open command prompt and type this: adb devices
You should see 1 of 2 things.
1) The words "list of devices attached" followed by a 16 digit long ID number a gap and the word "device"
2) just the words "list of devices attached" and then blank and nothing else?
If a device ID is returned then you can proceed with the following. Otherwise you need to do some additional trouble shooting
Proceed here:
Once it is detected by Windows and shows up in Explorer then unplug the phone and go into settings and developer options and check enable USB debugging. Once you have done this it should allow your device to be seen in DL and recovery modes.
Troubleshoot: If not detected try the following:
1) Reboot the PC and plug into a new USB port that you have not previously plugged into.
2) Try disabling USB debugging plugging the device in and then unplugging it and reenabling USB debugging
3) From the status bar try switching modes between MTP and PTP modes. Wait a good minute or so between to allow Windows to detect the driver change. Tip a good indication is your notification tray Icon with green USB disk with a magnifying glass swirling around....Note if you cannot see this at all you probably should drag it into the notification panel so that you CAN!
4) Open up device manager again and ensure no yellow exclamation marks !
Once all this is right and you can get List of devices attached followed by an ID number then you can for sure be able to detect your device from Odin. Make sure you are running Odin 3.04, run it as admin (not necessary but have heard that it helps?)
Good luck

You can try with minimal/no drivers i.e. uninstall kies if you have it and delete the drivers you might have installed on your own-it sounds counter productive but it has worked for me a few times.
You can also try to either install kies or the drivers separately.
Try the forum for your own phone, the people there might know better about this problem.
Also what OS are you on?

I will give all that a try. I'm on 4.4.2 build NH3. That's why I need Odin, to get back to build NE3

debugging mode and rooting

I installed all motorola atrix 2.2.2 froyo drivers on a xp sp2 and was running good then put the phone on debugging mode and connected by usb but windows was like looking for other phone and asking me to install again for drivers i didnt installed so using the last version of superopenclick then hit root but it just stay on looking for device and never found it. so cant root
when I turn off debugging mode all is ok again and windows doesnt ask for drivers .
Simply install the drivers windows is searching in debugging mode and try again. I don't know why but it needs two kinds of drivers sometimes

but after this fresh install i am unable to go to fastboot , somehow i installed flashmode drivers
i evn installed the drivers from fastboot-drivers.exe but no use when i start flashtool and try to enter fastboot mode i get an error message saying the device drivers are not installed , install these drivers from flashtool folder
what do i do ? evn in device manager when i update it doesnt find any software.. when windows try to install s1boot fastboot drivers it shows not installed

I think i had that same problem too, and took me some time to find the right answer, it is probably windows that won't install unsigned drivers, so try reboot, and press F8, and allow installation of unsigned drivers, though i just wrote a CMD code at that page i visited, but i can't find it now lol.
