Hello
Few days back I installed CynogenMod on My phone. Everything worked fine for few days and when suddenly I tried changing the APN settings yesterday and it wasn't happening. Then I needed to transfer some files on my phone again it didn't recognize it.
The pc drivers are all fine.
It is just charging and not showing any usb options.
adb is also not recognizing the device.
Tried different USB cables and USB ports? Tried booting TWRP and mounting partitions?
I removed Cynogenmod and there is no os installed. Now adb is not recognizing the device.
When i connect the device to the computer the connection sound comes, but nothing is visible in device manager or in explorer.
can anyone please help?

No need for adb, use fastboot commands to flash a factory image or use wugfresh nrt.
Try deleting drivers and reinstalling.

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.
Hi Guys,
I've had a few problems with my N5 recently...
If I plug my N5 into my PC via the stock USB cable and boot into the Bootloader (PWR+VOLDN) then it will allow me to flash the original N5 firmware, located here: https://developers.google.com/android/nexus/images, this would indicate to me that there is no issue with the actual devices ability to transfer files via USB connection... Right?
No!
For some strange reason my phone will allow me to push a full factory image to it and will also process any Fastboot commands that are sent to it but as soon as you boot into something like TWRP and try to control the phone's ADB functionality it will not find the device at all! The new MTP option in TWRP 2.8 will allow my computer to see my phone's MTP connection for about 1 second and then will immediately disconnect, the same happens when trying to connect to MTP from within Android too.
USB debugging doesn't show that it is connected when my phone is plugged into my PC and Windows makes the 'device connected' sound and then straight after makes the 'device disconnected' sound...
Any ideas? I am certain that this is an issue with my handset's hardware or software rather than any of the computers or cables... I have tried 3 different cables (including the stock cable) and also three different computers (Windows 8.1 @ Work, Mac OS X @ Work and my own personal PC running Windows 8.1 & Ubuntu @ Home)... All OSs and all computers run into exactly the same issue, device connects briefly and then disconnects.
I have troubleshooted issues relating to the driver. This is not the issue... Device Manager cannot even see the hardware after the disconnect.
Thanks for any help in advance,
Lewis
Also:
-Android does not detect that the USB is charging the device unless the device is booted with the cable attached (if it's not attached before the 'Google' screen then it can't see the USB input at all, within android or TWRP, of course...).
Having the exact same problem. Did you find a solution?

It's most likely a driver issue.

Not a driver issue.
3 different Nexus 5s, 5 different workstations. Other two Nexi are fine on all 5 PC's.
1 PC used for ADB forensics, 2 used for ADB development work, one known working for ROM'ing / rooting.
Phone has been factory reset, factory ROM'd from Fastboot. Connects fine on Fastboot. Will not connect on ADB / MTP.
On a fresh PC / phone reboot, the PC will detect the phone for just a second and then it will not reconnect until process is completed.

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.
Dear all,
Please Help me. My One plus one is on CM12 official rom (rooted). Problem is when I connect my phone to computer and use ADB it is detected (adb devices: number & devices detected) but when in fastboot (fastboot devices : nothing is detected) I check in my device manager (yellow triangle on android ) My problem is why CAN it be detected when my phone is on but NOT during fastboot.
Necessary checks done : USB debugging, Universal driver, SDK installed, USB driver reinstalled again, tried changing usb ports on computer, tried on 2 laptops)
I am helpless, tried checking on forums can not find the answer.

Tried adb reboot bootloader then phone boots into fastboot mode but from here..
is total no connection. Tried checking fastboot devices (nothing), fastboot reboot (waiting)
then i tried as u said unplug & plug in (not recognize) from here adb cannot be written anymore. (no more commands can be typed). Tried others like down loading Pdanet ,force install driver..Nothing works. Thinking ,did I corupt the bootloader while I was rooting it last time.?
I think if something was wrong with bootloader you could not either boot .
Do you use antivirus to pc?
Try without antivirus
What happening the false is from computer
Mine is reverse issue. When in fastboot mode, pc recognizes OPO, but when OPO is normally connected to pc, adb is not working. Its charging and can transfer data through USB, but OPO is not recognized through adb commands. Device Manager too recognizes my OPO only when it is in fastboot mode and not when normally connected via USB for data transfer.
I have a software, through which I can REVERSE TETHER my PC's internet to my mobile via USB. Because my OPO is not recognized via USB in normal mode, I can't do that. Any idea, what's wrong with my OPO.
(I have installed Android SDK and google usb drivers, for my OPO to work in fastboot. I have rooted. My pc runs on win7)

Install pdanet+ for win
As of 3 days ago my phone is no longer detected by windows 10 when I connect via USB cable.
I didn't change anything as far as I know.
Default usb setting is MTP
I've tried USB debugging on and off
Uninstalled drivers from pc (and the drivers didn't show up when I reconnected in phone) and reinstalled- nothing.
Fastboot and ADB not working.
Device manager shows nothing.
Tried several different cables and computers.
The only things that worked were usb otg drive (sporadically), charging (warp and from pc) and MSM flash tool.
I was able to flash OOS with MSM (from resurrection remix ROM) but the problem persists.
I've checked the usb port for fluff and it's clean as a whistle.
Any ideas?
Thx.
Why does nobody love me?
