Hello,
I'm an average user just following the creative work on XDA since I had my htc HD2 lion.
I hope you can help me
I have international galaxy note 2 GT-N7100
I rooted it long before 4.3 update and it was working great.
I updated through Kies without uprooting, it showed error at the end and switched to phone recovery and was updated to 4.3 and worked great.
Device status showed modified for a few days then showed official.
I tried to Root it using a method without pc but failed and showed patched kernel error.
Then I updated to 4.4.2 OTA from the phone and it worked fine and shows official status.
The problem now is the micro USB can not recognize pc] (it does not show USB icon and connected as MTP in the notification bar) and can not be recognized by pc (it does not even show USB device not recognized) , also can not recognize OTG storage ( it detects the OTG cable but not the flash disk.
I have tried everything related to all components including pc, drivers, cables, and all are working very fine with my Galaxy S3 including connection, drivers, Kies and Odin recognition.
I hope one of the senior developers can help me.
I would be very grateful to any one who can offer a solution
my friend is having the same problem. Whenever he connects his note 2 in any pc , his phone only charge and no usb. if you have found any solution then please let me know.
Try replace your usb cable.
Update March 13th 2016: SOLVED!

Hi everyone!
I come to you today with a very nagging situation, and I'm not being able to figure it out! All of the sudden, my phone stopped being detected when I tried to connect it vía USB to any PC.
I would post a screencap of Windows' error here. But I posted under 10 times so Forum's Policy doesn't allow me.
Already tried:
1) Connecting the phone to 5 different computers (running on windows 7 64 / 32 bit, windows 8.1 64 bit, windows 10 64bit)
2) Enabling and disabling "USB Debugging" before plugging the phone to each computer.
3) Uninstalling and reinstalling ADB / LG G4 drivers on every computer that the phone was connected to
4) Different USB cables from different phones (Stock, Samsung Galaxy S4, S5 and S6, Nexus 4 and a generic USB cable)
5) Connecting the phone while on Windows' "Safe Mode" (Windows 7 64bit )
6) Factory reset.
7) Letting my phone discharge completely, and charging it through USB.
8) I was adviced to find the "adbkey" file and delete it. Saddly I couldn't find it anywhere (Not in Windows nor the device)
9) Accessing the "Hidden Menu" by dialing "277634#*#" => Port Check Test => Enable Port Check test
Relevant info:
* LG G4 H815 [not sure if H815AR, H815P or H815T, but certainly not european. No official bootloader unlock ): ]
* Phone charges OK with stock charger and others.
* Just before this started happening, I used a Samsung's Galaxy A5 charger.
* No notification that indicates that the phone is connected. So I can't switch from MTP to PTP mode. Is there any way to do that other than when the phone is connected to a computer?
* No new apps were installed on the phone before this started happening
* I rooted my G4 a long time ago (3 months +) by flashing it with a rooted image.
* The same USB cables were used to connect other phones to any PC and worked OK.
* Not using and external SD memory card
* Last thing I did when I was able to connect my phone to my personal notebook: I transferred some videos and photos from my phone to my PC.
* My grammar and English writing skills suck
What I think it is:
* Bloody Android 5.1. I wish I could flash the phone. But I need a PC connection to do that... yikes.
* Samsung's Galaxy A5 charger that I used. According to this theory.
Any advice/suggestion/possible solution/encouragement will be very very much welcome! I'm going crazy already.
Thanks in advance for your time and attention.
Love from Argentina,
Ok. I just did a factory reset and the problem persists.
Go to users, select your user name and and click on .android folder. Delete adbkey.

Hi! thank you for your reply.
I'm afraid I don't know where that file is.
I've tried a windows search for "*adbkey*" without luck (hidden and system files are showing).
I also manually looked into "C:\Users\<Username>" and there's no ".android" folder.
Also looked into my phone (through "Wifi transfer" app) and there's no such file
More relevant info:
I just remembered, just before experiencing this problem I used my sisters' charger one day (Samsung Galaxy A5). Could it have messed with some Integrated Circuit inside my phone? I've read here in this forum, a Mexican user presented his theory about chargers messing up USB connectivity on android phones.
¿Does anyone have more info about this? I'm not able to flash my phone, since I could never unlock bootloader. And obviously I can't do it through my pc because it's not detecting the device.
solved it! I just added the solution on the main post, highlighted in green.
I just connected the phone and I was able to access normally.
but if my g4 not work what i can do_؟؟؟؟؟؟؟؟
Just factory reset
I had the same problem in my lg g4 h815t. I just reset the phone and then my phone was detected by the pc .
Or just use http://tinyurl.com/adbiso

Hey, I am facing same issue but with nextbit robin after charging it with oneplus charger. I am not able to access the service menu. Should the phone be rooted for it ? It will be very helpful if you replied.
I have the same problem, but I already did all the things you did, but it still has the problem. Every single PC doesn't detect it, it only charges, what should I do? I have unrooted my Lollipop 5.1 and can't root or flash any rom anymore. Can someone help me?
Solution for my N910V Note 4
Device: (Note 4 rooted, 5.1.1).
I searched all over the place and tried everything to get my phone to connect to pc again.
What finally worked for me was using: Shortcut Master (Lite) app .
In app I searched "USB" within System Apps
Selected "USBSetting" (com.sec.usbsettings.USBSettings)
Launch > Selected AP > MTP + ADB > Reboot
My USB > PC working again.
Hello everybody.... I write because I'm facing a problem that's causing lot of headhache:
I have this Samsung A3 (SM-A320FL) with broken screen, no USB debug, no root and stock recovery and I need to retrieve data from it.
I tried almost everything:
- programs like Dr.Fone, but the model wasn't supported
- connect the smartphone to the pc, but I can't confirm the mtp connection from the first
- used a USB otg splitter, one port filled with a mouse and another connected directly to the pc, but the smartphone wasn't even seen
I was thinking to flash a custom recovery to use adb, but:
I don't even know what version of Android is installed, nor firmware and I think that encryption was automatically turned on, so unless someone of you has a solution, the best for now is to repair the screen.
The situation is interesting but honestly I didn't see as many solutions...

Hi,
I have a question regarding DEX...
My Note 10+, Windows 10, DEX and samsung USB driver are up tp date. Everytime i connect, DEX launches on my PC, i get the notification in my phone that DEX is running. However, in my pc, DEX will just shut down immediately after connected. This had happened since i received the phone after it was launched in my country. Initially DEX was able to run, occasionally. All i need to do is to restart my PC, and DEX will be able to connect. However, after the 2nd phone update, I'm unable to use DEX anymore. I used the original samsung cable and a few other cables to connect to PC, USB C to USB 2 type, tried them on all available ports in my PC.
Additional Steps other than updating phone and DEX that i had taken to try to resolve the issue:
1. Clear phone cache
2. Restart pc and phone
3. Change cable
4. Google (unable to find similar issue)
5. Search through samsung FAQ.
6. Searched in this forum.
Any help will be much appreciated.
Thanks in advance...

Dex was working for me ever since i got my Note 10 +
months back (launch dateAug / October ..? ) with my Lenovo laptop.
However a few day back, i got a notification to update Dex.
(I have done a few Dex updates.) No issues.
Done the update and now basically have the same issues as you.
Launch Dex.... does not launch..
Notifications on my phone Dex running...
Bottom line,
I'm sure it has to be a Dex bug..... software .!
I did not even attempt to investigate, as all Dex was working 100.%
Just waiting for the next Dex update.
My phone companion which was always buggy, is now working fine.
Good luck

Just an update , to my post above .
I again , downloaded the "Dex exe "from the official Samsung site .
https://www.samsung.com/za/apps/samsung-dex/
Then "ran/launched " the exe , that then prompted me to completely ,uninstalled Dex on my laptop .
After uninstall ,i again ran the exe to install .
I did not have to install anything else eg ..drivers again .
Dex is now working ( launching ) ) on my laptop .!
Secondly/alternatively ,
have you connected you phone ,to just a capable tv /monitor and launched Dex this alternative way , is " that method" working , for you ...??
Good luck .
I'll try your method and report back.
As for 2nd method, i had only tried to connect to the usb hub that came with my monitor (and of course the usual usb ports on the motherboard ). So far it's a no go.
Thanks for the suggestions and hope it will work.
Much love!

Some additional questions, Maybe it can help...?
Does Dex work, if you connect with cable to only a eg tv screen.?
I just tested my device,
connected my device with HDMI/USB C to a tv screen and working fine..?
Is your pc /laptop, anti-virus may not killing Dex..?
Or your Note 10 device anti virus killing it ....
if you have any installed on device.?
Have you maybe disabled any apps eg with Package Disabler etc and now hav a knock on effect.?
Can you check with someone near you or local forums
to see if Dex is working for them.?( If they have any issues.)
Is Dex not maybe blocked by service provider.?
If Dex shuts down, does it pop up any "toast texts"? before shutting down?
If it does install a any "Toast " app form Play store
eg "Toast Source" app works fine for me. to "catch"
the toast popup, so that you can read reason for shutting down.
Question is according to you,
Dex starts, but is killed by either
the Device System or a 3rd party app?
Yes "something" eg app, anti virus etc is killing Dex,
as you are able to install Dex fine etc...... until launching Dex.!
Then Dex gets killed by.....?
Look for the culprit /app thats killing Dex..!
I can imagine this must be very frustrating for you !
Good luck
I've had the same issue for a every now and then. The fastest and easiest way I found to fix this is to pull the shortcuts and notification down There should be a small notification "Android System" USB for file transfer. tap this and change the USB mode to something else and then change it back to file transfer. This should allow Dex to see the phone or the phone see the PC again. Hope this helps!
Hello,
Can you try to update the Dex app with aptoide ?
Do you use CCSWE and you deactivated a service related to Dex ?
I had similar issue, it doesnt work if Samsung Keyboard is disabled

THIS! Re-enabling the Samsung Keyboard stopped DEX from crashing. Thank you, it's been driving me crazy!
I've tryed another USB port and it work fine.

Turn off Link to Windows. This happened to me yesterday. On the second try I say a very brief pop up on my phone telling me to turn off Link to Windows.
As soon as I did that it worked fine.

You may have to turn off "Link to windows" on your phone first.
I got the Samsung Note 10+.
i have been trying to troubleshoot this same problem for the longest time, where i connect my phone from usb-c to my pc, press start now on phone and samsung dex will just close immediately.
finally today i went to the my phone setting, searched for "dex" and saw "Samsung DeX" under "Advanced features".
This is my first time going into "Advanced features" and I noticed many settings were turn off here.
So i turn on "Samsung DeX" and it seemed to have worked!!! I press start now and the connection went ahead to my pc and samsung dex started loading with the UI. I have not seen this app for a long time.
Now the question on why is it turn off by default? I don't know. I was able to connect to samsung dex on pc without problems.
i tried again and it didn't work! so i had to trial and error again. i can't do the normal unplug and re-plug in usb and press start now because samsung dex will exit immediately like before.
I had to plug in usb and then press the Samsung DeX to turn it on in my settings and it worked again. I don't know why it has to be this way.
I also went ahead and turn on Link to Windows, Call & text on other devices, Continue apps on other devices as well. Just because I want to use all these features when I connect my phone to pc.
hope this helps anyone with similar situation
