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.
All I see is a google logo, not rebooting just staying on the screen. I am pretty sure I deleted the operating system, but I can't seem to get in recovery. What lead up to this was me not being able to connect the device to windows over usb, nothing in device manager, I couldn't even get adb to connect even through twrp sideload. But now I think I caused a whole new issue. I'm just trying to get back to stock rooted lol. Advise?
Edit: unpluged battery and replugged it in, got into recovery now, still having issues connecting so I can flash a rom.
Edit: I have the google usb driver installed from the android sdk. I still can't see my device in windows device manager nor I can't see it through adb. still searching around for a solution.
Edit: I found my old rom still on the device so I was able to install that to actually use the device. I still can't seem to connect to the pc in any way though. I have usb debugging checked drivers installed. Windows just doesn't seem to think a device is there.

Try toggling MTP and/or PHP in USB options.
Your device might show up as an adb device in Device Manager.
Edit:
Some more info here:

Use a different usb port, different cords, or even a different computer, until you get a pc to recognize the phone.
I had this. It was because not all USB leads have data. Even some that do are wired different. Use the original or HTC work fine with N5 as I've both brands

Well on my 4th cable, what do you know it works just fine. Feel a little silly but thanks everyone.
Hello,
i tried to update my Nexus 5 to 5.1 by using adb sideload.
First i installed the driver which did not work, i removed them and used an another and the device was recognized after that on windows.
So I started the sideload and it stopped at about 60% and the USB Connection was lost. I can not see the device in the device manager and if i use my linux computer i can not see any new entry if i use 'dmesg'. I used an another USB cable to check if this is broken. I tried to format the cache and it now still boots to the recovery mode.
Can it be that the USB driver in the N5 is broken now?
I wanted to prevent a factory reset, but i dont think that a FR will help here if i can not connect even in the recovery mode
Any suggestions?
Thank you!

Hmmm, intermittent ADB occured before attempted sideload falure.
Boot to bootloader and see if you can
fastboot devices
If you can detect the device in fastboot, but still cant ABD, then maybe take a look here http://forum.xda-developers.com/showpost.php?p=59420668&postcount=322
After looking there, if you are absolutely certain that it is not a driver issue, you might be looking at a hardware failure of the charging port.

If it were me, I'd replace the port and re-attempt ADB sideload.
Hi all
I've had a soft bricked device now for 4 days I've read almost every post on the net to resolve this issue. So my Samsung S6 SM-G920F is stuck on the blue screen saying "An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software." I can get into download mode 'recovery' however my phone will not connect to my computer via usb. With an error message stating "usb device not recognised. The last usb device you connected to this computer malfunctioned and Windows does not recognise it.
I have tried:
Changing cables
Changing computer
Deleting drives - rebooting comp to reinstall
Removing kies
Removing smart switch
Reinstalling smart switch
Reinstalling sub drivers
Editing power options and disabling USB ports
Entered HP BIOS and ran a port check which did however result in failure but then same situation on another HP laptop with working ports.
The device is charging when plugged in but not available to flash and reboot/bootloop.
If anyone has a resolution I will be eternally grateful.
Thanks in advance
I recently rooted my s8+. Now when I connect it to my PC (or even my wife's PC), I get the following on my phone, "Attention: the connected device is unable to access data on this device. Please disconnect the USB cable and try again". I'm using the USB cable that came with my phone and the issue is happeing on 2 different PC's. I have USB debugging checked and set to MTP.
in settings, Switch on Developers options in configuratien. Then there is a USB modus setting. Set it to Charging rather then MTP Transfer.
try another USB cable and update the drivers in device manager.

Ok, I've tried your suggestions but the problem still persists. What's worse, I unrooted the phone and did a factory reset and it STILL is unable to access the data on the device.
