well, why don't you like ICS I'm just curious about that !
about that problem ...uninstall Kies then restart machine and try to perform a clean install of drivers yes again by Kies but don't connect device at this time and restart PC after installation then connect phone to PC activate usb debugging
also if you like to play with custom ROMs (= flashing ) then I suggest to install Android SDK to get adb.exe/fastboot.exe
now activate usb debugging on your phone connect it to PC then enter from cmd.exe -open console in adb.exe folder location usually ~ \android-sdk\platform-tools\
adb devices
if you get answer it means you have drivers installed
also start Device Manager start/run/devmgmt.msc and connect phone to PC (activate usb debugging previously ) you should see adb interface listed -take a look at picture
now try to start phone in fastboot/download mode and connect to PC it should detect phone
open cmd.exe in fastboot.exe folder ~\android-sdk\platform-tools\ then try this
fastboot devices

SGS4G Drivers Problem?

I hope I'm posting this in the right place. I recently picked up a SGS4G and I immediately wanted to root it. When I plug my phone into the computer, however, the computer doesn't recognize it. The phone recognizes that it is plugged in (green android pops up, gives option of Kies, Media, or Mass Storage), but nothing happens on the computer end. I've downloaded about a million drivers and still no change. I've tried downloading Kies for drivers, but Kies doesn't even recognize a phone is plugged in. I've even downloaded drivers for the original Vibrant, but no luck. It's frustrating because I think that is the only reason my OneClickRoot keeps getting stuck on "waiting for device". Anyone have any ideas?
If you're using a 64 bit system, make sure you get 64 bit drivers.
Got a 64 bit system, got the 64 bit drivers. I even tried the 32 bit drivers just for the hell of it. Nada.
I dunno where you got your drivers, but here's the exact one I used.

I had problems with my drivers before. I downloaded Kies Mini from Samsung's site. I used Kies to install the drivers and haven't had a problem since.

Ditto what Jerry said. They work like a charm.
Well I finally got my computer to recognize that my phone exists, but now I keep getting a message saying that the drivers have malfunctioned. I've uninstalled and reinstalled a few times now, and no change. I can't get Kies to see my phone, or I'd try to download through it.
I'm at work so I don't have my Kies with me lol but you should be able to install the drivers. You can't do anything with Kies because the drivers aren't installed.
Look at the "options" in Kies to install drivers.
Sorry for the non technical directions. I only used Kies to install the drivers that one time.
Kies doesn't give me any option to install drivers. There isn't even an "options" tab. Even with my phone plugged in, Kies stills asks me to plug in a device. I've tried connecting my USB through Mass Storage, Media Player, and Kies. I've also tried all the above in USB debugging mode. I've even plugged it in in download mode. Still nothing. I keep getting the message that the drivers are malfunctioning.

Try this (sorry if I made this seem novice-like, but I just want to try and be clear):
Open a command prompt
type this, followed by Enter: set devmgr_show_nonpresent_devices=1
type this, followed by Enter: devmgmt
Once Device Manager opens, click View on the menu bar and select Show Hidden Devices
Expand both "Modems" & Universal Serial Bus controllers" & uninstall anything that has Samsung Android USB Composite Device, Samsung USB Composite Device, Samsung Mobile Device, Samsung Mobile Modem, etc.
Once the devices are gone, maybe reboot (probably not necessary, but why not?) and try the USB driver install again.

Ya, I didn't think there was an actual Options tab that is why I put options in quotes. I remember hitting install drivers when I installed mine months ago. It was very easy.
It sounds like you need the kind of help Steven is giving.
When you do get your computer to recognize your device I highly recommend installing the drivers through Kies. After many many flashes the have never let me down.
I wish I could be of more help. I've seen your problem in here before and our Helpful Members always get it figured out.
Best of luck!

Try USB Debugging
Oddly enough try only using the same USB port you originally installed the drivers on. I have noticed with windows 7, it tries to install the drivers when you change USB Ports, then again it should do this if they are on a separate controller.
As stated above, use USB debugging.
Hopefully we'll get you an answer that works.

Well, I tried Stephen's method, but still got nothing. I keep getting the error message. I just don't understand why the phone will recognize that it's plugged in, the computer will recognize that SOMETHING is plugged in, but it won't recognize WHAT.

Bummer, I Really hoped that would work. When you go into Add/Remove Programs does it show that the USB drivers are listed? If so, remove them there and re-try the installation.

I've tried that too, multiple times
I tried something different this time. In device manager, under USB Controllers, instead of deleting all the Samsung stuff, I deleted EVERYTHING (based on an idea I found on a Windows 7 help page dealing with error code 43). When I plugged my phone in, every one of the items I uninstalled reinstalled, except for "Unknown Device" (I'm assuming that's my phone), which came up failed. I'm not sure if this helps at all with diagnosing the situation, but I thought I'd throw it out there...
Did you retry Stephens suggestions after uninstalling everything?

[Q] Can't get past "Waiting for device to be detected" in debugfs

I need help here... I'm trying to root this thing and I don't know if I have a software problem, USB issue or phone problem.
Running Vista Hpme Edition 32 bit.
I downloaded the Samsung Drivers 1.4.6 or something and the comp said they were already installed. Now when I plug my phone in, it tries to install drivers again and hangs up on CDC Serial and MTP. It asks for a CD with driver info.
I tried deleting the USB drivers and restarting the comp to reinitialize them. I did a factory reset on the phone. Then I plugged back in and I am still at a stand still.
Since it said the drivers were already installed, I tried debugfs to root it. It just stays stuck at "Waiting for device to be detected".
How do I get these drivers to load properly so that debugfs can detect my phone?
In windows explorer, I can see the I535 and my internal and external cards... Grrrrrrrr

At that prompt it should also ask you to install them either way, choose yes... install the drivers then try opening up Odin and see if it can see your phone....
Your phone will have to be in download mode, and Odin should show some sort of recognition as in a COM port address in the upper left....
If that fails, follow the guide in my sig, droidstyle put together a great step by step instruction....(You can also follow the sticky about how to return your phone to Verizon in this forum that I put together, except to choose root66 and don't re-lock the bootloader)
Nevermind... I installed Kies and that seemed to remedy the issue. Thank you, though.

Kies should install the drivers for you.
Uninstall Kies, download latest version of Kies and install it.(with phone disconnected).
Once you install and open Kies, update it in case it´s not the latest version.
Put your phone into debugging mode:
settings/Developer options and select "Android Debugging".
(or in some versions of Android it may be: settings/applications/development and select "USB debugging").
Now(with the phone ON) connect the phone via the USB cable. Kies should recognize your phone and your drivers should load. (You have to wait while Windows is detecting new hardware and setting up the USB drivers...Windows should advise you when the "new hardware" is installed and ready to use.)
Unplug phone and restart PC.
Now when you connect your phone to PC via USB, press the "connect USB storage" button on your phone to complete the connection.
Hope this helps

Usb drivers for your android phone

USB Drivers are let your PC communicate with your device.
If you are executing some ADB Commands, you will need USB Drivers installed which will let the ADB server on your PC communicate with the ADB client on your device. If there are no USB Drivers installed on your PC, you will not be able to perform activities on your device via the PC.
First of All I would recommend you to install Universal ADB Driver Installer.The Universal ADB Driver installer detects your phone and installs the ADB drivers for it.This tool developed by drsmart is your solution to the “device not found” error you might get on executing ADB commands.

Here we go, I have the Galaxy 3 d2att I747
Rooted
I was running CM 10.2 with latest nightly, I think 20131208 and decided to update to CM11 via my Cyanogenmod updater but before I did I had read somewhere I should change from CWM recovery to TWRP so I downloaded Goomanager and updated to the TWRP version for my phone then went for the KitKat update and thats when the trouble began.
I am now stuck in a boot loop even if I try to boot into TWRP all I get is the TWRP boot logo then straight into boot loop again. I am almost positive I did a factory wipe as well as cache/dalvik.
Not being able to use TWRP to get into recovery I thought I would just use Odin but I can't get any of my laptops to recognize the phones USB, I just get the windows usb driver error and have tried to install the drivers manually via device manager using my samsung 7 chronos with windows 8.1 and my acer with windows 7. I updated drivers using Samsung Kies and from the website, no luck.
I also ventured into an area that I have no expertise in but I guess thats how we learn so I downloaded the Android SDK thinking I could use it to download and install the google USB drivers that way, but I can't get out of boot loop to make sure USB debugging is checked. The only thing I can access is the stock download mode which would be great if I could use the USB connection.
What am I missing? Any suggestions?
USB Not Recognized Error
I noticed that my phone suddenly stopped being recognized on both my Windows 7 and Win8 laptops. I have been trying to fix it with the drivers but to no avail. However, I plugged my phone in with a different USB cord and voila it was recognized and working. Maybe this could possibly be a simple fix.
My computer stopped recognizing my Skyrocket
Hi Everyone,
I also am having trouble with my win 7 computer recognizing my Skyrocket suddenly. I have been using several KitKat roms and they have been working just fine, except for some reported bugs that the CM devs are working on. I even was able to connect to the computer and explore both my internal and external drives. Then suddenly that stopped and the computer gave me a need to get drivers warning. I've tried to download drivers from Samsung and the computer says they are already installed. I also tried the universal driver download and got the same message. Any help would be appreciated. Like the others on this forum, I wouldn't be able to odin if I got in trouble.
Thanks for your concideration,

soft brick
I face bad experienced, the tablet can not boot ( after install TWRP ) but enable to enter the fastboot mode and can be detected by the computer as android adb interface but adb can't communicated with the tablet. (list of devices atached)
I do have a backup file ( I make it before soft brick, I make backup using dd command, because I don't have cwm/twrp recovery ).... but how to flash it ? Tablet chipset is wonder media 8980 OS android 4.2.2
I can not flash it by adb/fastboot.
Maybe someone here can give me a little guide for how to....
I really appreciate for your kindness
Hey, I made an expirience, which might help other users as well.
I have a Sony device (Z1C) and use Windows 10, maybe this will help for other brands and for other Windows 10 users.
I installed drivers for my device and was able to use adb. When I put the phone into fastboot mode, it was not recognized anymore. I found out, Sony has a seperate (updated, maybe?) driver for fastboot mode. When I tried to install this, the driver was not signed and Windows refused to install it. However, you can enter the UEFI (successor of BIOS) and enable installation of unsigned drivers (at own risk). Then I was able to install the fastboot driver and controll my phone in fastboot mode as well as in adb mode.
In conclusion: You might think you installed drivers, because you did, but maybe you did not.
Even on LineageOS page, many people fail to mention that, you DON'T and SHOULDN'T install any generic or universal ADB driver if you have Samsung device. As you can just install Samsung USB Drivers officially from Samsung site. Samsung USB Drivers already contain ABD interface driver just fine so Universal ADB driver is redundant for Samsung phones.

OnePlus One not recognized in My Computer

I tried to access my phone's internal storage but the phone doesn't show in My Computer. The Portable Device in Device manager says MTP USB device and it has the yellow triangle on it. The Samsung driver is the Android Composite ADB Interface with no triangle. I have debugging on but the MTP device driver always fails whether debugging is on or not. I used Koush's drivers found here on XDA but same old thing. The Portable Device used to show up as A0001 and /or One but now it doesn't and I don't understand how that happened. Can someone enlighten me and perhaps solve this problem? It's been very frustrating as I just spent 13 hours trying to get my phone working (Thanks Heisenberg for fixing) and now another 6 trying to figure this out. Please HELP if you can. Thanks!

Even I had faced this problem on Windows 8. I had installed drivers 4-5 odd times. But later I just flashed CM11S zip via recovery and enabled USB Debugging Mode and it finally got recognized on my laptop.
I was facing many issues with all lollipop ROMs. Hence I reverted back and now everything is working fine.
I, too am using CM11s as Lollipop has too many bugs for me at this time. Maybe I'll try re-flashing CM and see what happens. Thanks for the reply
My question is: How can one flash from recovery when the file that needs to be flashed cannot be sent to the phone because it's not recognized by the computer?
Nevermind...I figured it out and flashed 11S successfully! Everything shows up now on computer. WOOT!
