I wanted to use nvflash to bring back to clean slate. Could not get the USB driver issue resolved in Windos 7 or XP, Read the threads, just did not work. Also noticed that the USB connect to the GTablet stopped working, it woriked fine for before trying adp. Tried Linux and the device is not seen using LSUSB did see the device is I tried via USB debugging mode. I power on and hold the vol- button see boot screen then unit goes black. No usb connect to PC either after trying.
Reset the device to stock with CWM and PC USB comes back. Is there a utility or something to check the ADP functionality at boot level, has anyone had USB issues that can help? Is it a possible hardware issue?

Try USBDeview: http://www.nirsoft.net/utils/usb_devices_view.html
Disconnect the G Tablet from your PC. Then run USBDeview as administrator (i.e. right click and Run as Administrator in Windows 7). Then uninstall any drivers related to the G Tablet.
Now plug in G Tablet and it should be detected again and you can point it at a properly working ADB driver on your PC.
Have done that, but it seems that it is something on the GTablet that is causing the error. When is is malfunctioning no USB connections work and driver issues pop up, after set to factory the USB works and driver issue for storage go away.
So far I can tell that adp mode from power and vol - unroots my tab and I can not connect to pc. After re-rooting I can connect. Linux can not see device in adp mode.
Update. Returned the unit to sears for a new one and problem solved. I must of had a clinker.
Essentially What's wrong:
My phone is stuck in a boot loop, computers won't recognize the usb connection, and my sd card won't mount. My SD card is, however, recognizable if I plug it directly to my computer using an adapter.
What Happened:
I rooted my phone using CWM and Odin in order to remove bloatware and enable tethering. After enabling tethering, my computer stopped recognizing my phone. I tried everything to fix it including factory resetting my phone, formatting cache, data, system, and sd card all under the CWM boot menu (hold volup+home+power). Soon afterwards, my phone got stuck in a boot loop. On startup, it hangs on the white "Samsung" logo. While trying to fix the issue, I noticed that my sd card won't mount.
What I've tried:
I've tried this method, but it requires that I either have usb access or access to my phone. I've tried reinstalling the Samsung driver fifteen times. I've tried formatting the SD card in my computer. I've tried using different computers. I've tried using different usb cords. I've tried clearing the registry on my computer, I've tried scouring Google and these forums for a solution. Maybe I'm blind and missed something.
What I'm trying to do:
The way I see it, I need to figure out a way to flash the stock rom back to my phone. In order to do this, I need to get my usb to recognize. If I can do this, the rest is easy. Does anyone has any ideas on what can be done?

The phone not connecting: I have had this issue before. If you go into the device manager on the computer and show all devices, you can remove all the samsung usb drivers and the root usb drivers from the computer. Reboot the computer and leave the phone unplugged. it will reinstall the main drivers. reboot the phone and hold the buttons to enter recovery, it should still work even while stuck on samsung logo. connect the phone to pc and it should reinstall the drivers and connect properly.

Do you remember at all the name of the drivers that need to be uninstalled? When I plug in my Droid Charge, the computer attempts to install the drivers but it always fails. Under device manager I will then see "unknown deviced" labeled with a yellow exclamation mark. I uninstall that, then plug the phone back in but the same error occurs.
If there are other drivers that I need to uninstall, then I don't know what they're called. None of the devices in the manager say anything referring to samsung.

go to device manager and choose: view >> show hidden devices
then under the usb drivers look for and uninstall the SAMSUNG if any and uninstall the : Generic USB Hub if any, and uninstall USB Root Hub if any, and reboot computer.
THANK YOU
How don't know how I managed to miss this when trying to fix this over the past week+, but it worked. Getting rid of those root usb devices got my computer to recognize my phone, then I was able to easily use Odin to boot it back to the stock rom. Thank you so much. Crazy how such a simple solution can be the answer.

Hello, have tried uninstalling the USB drivers but Windows 10 re-installs these drivers upon restart. My Samsung SM-N750 is still not detected on via USB, and therefore cannot proceed with Odin firmware flash. Do you have any other suggestions? Many thanks.
Not sure when USB stopped working but nothing I've done let's my HTC One X (AT&T) connect via usb. I'm running CM10.1 and have tried both MTP and USB Storage and none of my PC's will see my phone.
I'm running TWRP 2.5, which I just updated today. When I boot into recovery and mount USB, my PC shows nothing. I boot the phone into recovery and the fastboot line says fastboot AC instead of fastboot USB. I've tried 3 different cables, an older cable that came with a MyTouch 4G, the HOX cable, and a generic USB cable. All three cables work with my wife's HOX, though hers is stock.
I've also tried on two different laptops (one vista, one win7), my PC (win7), even ran an Ubuntu VM on my PC and nothing.
HTC Sync Manager has been installed and is currently uninstalled though I do see the HTC Driver in Programs so it is there. Some times when I plug the phone in I get an error from Windows about the USB device not installing right. One odd thing is I don't see the device anywhere in device manager, nothing other Other, Android Devices or anything like that.
Developer options are turned on, with Android debugging, USB debugging notify turned on. Root access is set to Apps and ADB.
I've tried other things I've found such as turning the phone off and plugging it into the USB and letting windows detect that way. Pretty much at a loss at this point.

Helping a gentleman with the same issue in another thread, it sounds to me like a hardware issue.
Hi,
Have a TF101 tablet here stock rom, stock recovery...
However it seems the USB will not detect on a windows PC tried multiple cables multiple PC's tried from recovery nothing is detected in device manager at all. Tablet doesn't even detect that its connected to PC either.
Is there anyway to root this thing without USB??? I need to root it so I can install recovery and flash another rom.
Thanks,
Which Windows version are you running?
If you use Win 7 and prior you should be able to connect with the universal naked drivers manually installed from device manager
Win 8 and above need driver signing disabled or they wont install the driver and the PC wont see the TF
If you have already tried the above, you might need a new cable

Thanks. Well i tried windows 7 x64 and windows 8 x64, neither showed any device or unknown device in device manager... Tried multiple cables as wel, no dice...
Shouldn't MTP work regardless of drivers installed in windows 7/8 ?
Are you putting the TF into APX mode?
Connect TF to PC USB > Power Off TF > Hold Power & Volume Up until the PC recognises it (Only takes a couple seconds, nothing appears on the TF screen) then install drivers
You need APX mode for Easyflasher
For normal media transfer, it will still need to install at least some USB type driver, as do all USB devices to function, possibly not the APX drivers
Check in Developer Options > USB Debugging mode
Try it enabled and disabled with the TF plugged in
But really the MTP drivers are not what you need if you want to root. you need APX mode to work (As above)

Doesn't seem to do anything when I hold power vol+, the screen of the tablet (blank/off) and on the pc nothing is being detected.
I can get to the bootloader/recovery via holding power vol- though. Also tried USB debugging mode... nothing is detected whatsoever... ordering another cable on ebay will see if that works but I doubt it since it seems to be a common issue with this tablet (port not working with pc)
I edited my post
Nothing will appear on the TF screen in APX mode until data transfer begins
The cheap non genuine cables are renowned for data connection failing, genuine cables are recommended
I still have my original cable and it still works 100%

Using the original cable, I still can't tell if its in APX mode, installed all the drivers provided by asus, nothing is detected in windows device manager. I'm 100% its not being detected ie. no connection. I ran easyflasher anyway both sbk1 and sbk2 says it flashed recovery but it never did still the stock recovery is on the tablet.
Will try again once the new cable comes in, thanks.
Forget the ASUS drivers, use the Universal ones from the Easyflasher thread
Here's what will happen when its working as intended
When you plug the TF into the PC, no matter what mode it is in, the PC should sound the USB connect sound
When you power off the TF, then put it in APX mode, the PC will again sound the USB connect noise, then it will fail to install the correct drivers
That's when you open Device Manager, find the ! missing driver ! exclamation mark, and update drivers manually pointing it to the extracted Universal drivers
Once you have installed them, then Easyflasher should work as normal
So unless you actually have a hardware fault on the TF, or the USB ports of the PC, Id hedge my bets on the cable
Have you tried a different PC?

Ok, well ya thats the thing no sound or detection of anything when plugging it in, or going into apx mode, rebooting etc...
I tried 2 cables and 2 different PCs. Will try a new cable but I betting that is won't work either... we'll see.
Thanks again
No need to bother with cables and drivers, just download Baidu Root: https://app.box.com/s/pyehf9fh4xem3hy50dot
EDIT: The app has built-in su access management, but I'd recommend installing SuperSU from the Play Store.

Hello,
I've had a GT-N8013 for a few years and just recently decided to try something besides stock on it. Darn thing is, once I reset the tablet to factory settings (4.1.2) and got prepared to flash CWRecovery my PC stopped recognizing the tablet via USB. So obviously, I now can't use ODIN which kinda sucks.
The tablet lights up when I plug it in (Red X on battery icon, but that's understandable - although, it does that on the wall charger too), but the PC does not respond at all. No change in Device Manager.
Things I've tried or noted:
I have tried it on multiple machines and multiple ports
I bought and tried a new UBS cable
I bought and replaced the charging port
I have tried Kies, different drivers, etc.
Rebooting tablet/PC
With/without USB Debugging enabled
Any help would be wonderful. Thanks in advance!

Don't use Kies.
Download Samsung USB driver & install it, then may be restart your PC.
If you use MS Windows download ODIN.
If you use Mac or Linux download Heimdall instead of ODIN.
Download the ROM.
Set your GT-N8013 to Download Mode (ODIN mode).
Connect your your GT-N8013 to your PC.
READ the instruction for FLASHING A CUSTOM ROM!
