Yes, another DRIVERS DONT WORK thread..

Hey guys, just got my Tab a few days ago, its unlocked and its working great. I want to root, but my PC wont recognize it (running win7) and it says the USB device has malfunctioned... wth? I searched through some threads about the drivers, and ive tried 4 different ones, restarted my PC, AND my Tab, with no luck. No, USB Debugging is not enabled. (not a noob, just, simply not working)
Any ideas? I would appreciate it

I just got my tab 3hours ago. I got it to work.
Here are what i've done
1.go to control panel and see if samsung usb driver is there. If it is, uninstall it.
2.disable usb debugging on the tab
3.connect the tab to the computer.
Thats wht worked for me. Hope it helps. And yes, samsung has really got to work on the usb thing.

Unzip and run the attached file. Delete any old unused USB device and delete any Android, Samsung or other related device then reinstall Samsung drivers.

This helped me: my computer tower has front and back USB ports. Back USB ports are directly embedded in the motherboard, front USB ports are a wire run from the case plugged into the motherboard, but the front USB ports are on a different chip.
When I first tried using the ADB debugger with Android, ADB would not even find my device if I plugged the device into the front USB ports. If I move the cord to the back USB ports, everything works properly. Maybe this is your issue?

Thanks guys, I believe I got it working.

[Q] TF101 doesn't connect with PC through USB

Hi guys,
After upgrading to ICS I've been unable to connect my pad to the PC. This is usually not a problem, but last night I needed adb to re-root it. Nothing worked, nothing connected. Tried installing drivers and the Asus sync, but no luck.
Is this a known problem? Anyone got a solution? I doubt it's the hardware as I connected a few days before upgrading...

Found a solution. Went into Settings->Storage and turned MTP off and back on.

THANK YOU! Everytime I plug in my ET4G to the dock to charge it that stupid MTP crap always comes up. Had no idea I could disable it. Thanks!

yeah, this doesn't always help... I had the same problem when i first got my TF101, and i tried all the tricks, the one mentioned here with mtp, enabling and desabling debug mode, turning off and on with usb plugged in, and some others i can't remember... nothing.
In case anyone else is looking for the answer and the quick tips don't work, what did it for me was installing Android Revolution HD rom. I've read that this problem could also be bootloader related.
Anyways, cheers.

How to connect an ICS device to your computer
Step 1. Connect device to computer via USB
Step 2. Set USB connection as Media Device (MTP) (p.s. if you use a Mac you need to download Android File Transfer)
Step 3. Disable USB debugging if enabled
I hope this helped.

when you need turn off MTP it mean your computer doesn't have driver.
If you need using MTP go to asus page and download driver. it's easy to install driver ^^...
recently I can't understand why same file but the computer at my office can't install that file instead other computers working normal... maybe my work place using old windows version...

Like I wrote earlier - mine was actually in MTP mode, but I had to switch to camera mode and back to MTP for it to start working. Thanks for the replies, though. Hopefully it will help some other people with the same problems

N4 not showing up at all on PC

I'm not sure when this problem first appeared. For whatever reason, my phone doesn't show up at all when connected to either of my two PCs. It must have when I first rooted the phone (to load ChainSU) but I'm not sure if the problem is recent or occurred immediately thereafter.
USB debugging is disabled. When I plug my phone into a computer, it attempts to install the MTP Driver and fails. When I uninstall my device, it disappears and I'm unable to manually install the driver's I've downloaded from other threads. When I load into the Bootloader, my device is recognized by Fastboot.
I'm hesitant to factory reset as this will leave me unable to root if the problem persists, which is important to me as I can get rid of the yellow tint on this screen.
Any thoughts?

Are you definitely sure usb debugging is disabled? The phone should install as a portable device on your pc. Also ensure to enter your password onto your phone when connected otherwise the phone will not show up its contents.

Make sure for windows media player to be updated to the latest, for the windows mtp driver.

There are a few things you can try. Have you tried uninstalling the drivers completely then reinstalling from the toolkit? In the past, I've had issues where the phone wouldn't be accessible in some way on one computer but would be fine on another, so maybe try a different computer to try to narrow down the problem as to whether it's an issue with the phone or the computer? Also, this may sound a bit ridiculous, but simply switching USB cables and / or ports has fixed detection issues for me in the past as well--something to consider.

Remove any existing drivers (while phone is connected), do the same for other android devices if you have any, then reboot and install Universal Naked Drivers. Have always had success with this driver pack.

100% sure on both counts.

I have this same issue with my rooted nexus 4, I've tried 3 different computers and several cables and it never connects to the PC and only charges the phone. It doesn't even give me option to choose media files.

I've had this issue before, my Nexus/Computer was acting in complete stupidity. When connecting the phone to your computer you will see a notification saying "Connected as a media device" on your phone, just touch it, and change it to "Camera (PTP)". It might access the camera for you, but It actually accessed the storage for me.

Thats not the problem, it doesn't give any option. It doesn't show up on the computer at all and only charges. It's the same for every computer.

I'm thinking we've screwed something up with the phone's side of the MTP protocol - mine is totally independent of the cord/computer used. All the correct drivers installed.
Have you tried Factory Resetting? I'm really hoping this is a workable option.

If you have a recovery back up the current Rom and flash stock and see if it's working

if the phone is locked with a pin/password/pattern unlock it.

I had same problem on my pc yesterday. Even if the drivers installer showed up that installation was successful, somehow for a mtp mode system was using some other Microsoft driver. Correct one was only used in ptp mode. So when I connected n4 in mtp mode storage wasn't available, when I switched to ptp mode everything was fine. Turn on your usb debug, switch on mtp and connect. Go to device manager in system, find your nexus there and rmb on it and manually reinstall driver. After this my n4 is visible in system in mtp mode again.

The problem is that even if I switch between MTP and PTP it still does nothing, I have tried multiple cables, computers and have reflashed the ROM and wiped the device but it still does not connect with the PC. This is frustrating.

Is yours able to connect during Bootloader/Recovery? Fastboot/ADB have no trouble recognizing my device.
It's really odd that if these things work, meaning your USB connection is fine, replacing the all of software fixed nothing... unless MTP occurs at a much lower level of the OS (maybe kernel is corrupted?)

I've got a similar problem that others have posted - PCs not detecting my N4. I got it last Friday (2/1) from Google and after the registering process and updating to 4.2.1, I connected it to my Win7 laptop and it showed on the PC as a drive. But since I couldn't copy/paste Office docs to that drive and had to do that through Dropbox, I didn't bother trying to reconnect until Monday, at which time the PC didn't detect it. Neither will one other Win7 nor two XP (both with WMP10) PCs. Have tried multiple cables, all of which work with other Android devices (pre 3.0). I've seen several suggestions on this and other threads, but one major issue I'm having is that some of the fixes require enabling USB Debugging. For the life of me I can't find that option in the N4's Settings. Unlike my other phones, there is no Applications subcategory under Settings on my N4 (4.2.1, Build JOP40D). Can anyone help me find that option? TIA.
Edit - Found answer. Click on Build in About Phone setting 7 times. That activated Developer options. Now to try the fixes which require USB Debugging mode turned on.

[Q] Computer not recognizing phone when in USB Debugging Mode

I am trying to install the ADB drivers but my phone is not appearing in the device manager at all for some reason. I have USB Debugging mode turned on but all that pops up when I plug my phone in is the auto play that asks me if I want to open the device to view files. I have no android device listed in my device manager to install drivers to. I have tried on two different computers and my phone is not recognized.
I have the google edition on 4.3

have you tried a different usb cable?

Uninstall and then reinstall Kies and try again bro, that should work bro.

Try a different cable. Had an issue was GNex where it charged fine, connected to the computer okay, but couldn't get adb or use odin. Spent hours trying to figure it out, uninstslling, reinstalling, and rebooting everything under the sun. Then thought maybe, just maybe it might be the cable. Swapped it out, and it worked like a charm.

Can't get ADB Working on PH-1

Kind of a noob question. But I have enabled USB debugging, installed ADB and Android SDK, downloaded PH-1 drivers, switched from Charge Only, to MTP, to Camera. Nothing I do get's the Notification to allow access on my phone. Anyone had this issue? Thanks

I haven't connected my essential phone to PC, but which cable are you using? If you are using C to C cable that came with the phone, try to use USB A to C cable.

Assuming you're using Windows, open device manager, plug and unplug your device to see which one it is and with device plugged in, right click on it and uninstall. Then unplug and plug your device back in, and let it do its thing to install the driver.
Instead of uninstalling, you can also right click to update the driver and then choose from drivers installed on your computer and select the right one. I find from my experience, if you uninstall and then manually update if there's an issue works better.
Or start with trying another cable first just in case.

This!
When you plug the cable into the phone it should say in debugging mode.

Got it everyone. Reinstalled ADB and works like a charm.
