USB Issue

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!

Galaxy S6 won't connect to PC or MAC

Hi,
I have a problem with my Samsung Galaxy S6 - SM-G920F, it isn't recognized anymore by my PC. This happened after I made a ".nomedia" file to hide some gallery files. I deleted the file but the phone isn't recognized by any PC. When i connect the phone, it is only charging.
I installed TWRP for using the mount feature - not worked.
I installed the latest USB drivers from Samsung - not worked.
I installed Samsung Kies3 - not worked.
I installed Smart Switch - not worked.
I dialed *#0808#, turned MTP - ADB - not worked.
I installed through Odin a stock 6.0.1 Rom from SamMobile - not worked.
I turned on/off the USB debugging - not worked.
I used more than 3 USB cables - not worked.
Device Manager isn't recognizing my phone.
McBook Air isn't recognizing my phone.
The phone is not rooted and it has 4 moths since i bought this phone.
Is there something that I missed on my attempt to solve this problem?
Thank you for your time.

Same problem here, really can't figure this one out.. Tried all of the above too

Curious, in device manager under bluetooth it lists my Samsung s6 edge with a generic driver from Microsoft and I can't change it... Misidentified device? Do you have the same?

I assume your phone is unlocked/opened from lock screen when you are connecting it to your pc? ^^

Fully unlocked, & just no notifications :/

My phone isn't seen anywhere... not even in Device Manager

+#0808# is code for usb, you can try dial it (after last # it will run or not, depending on rom), or you can download Shorcut master from Playstore and try run it from secret codes inside app.
It has option to run it from dialer, or with SU if you are rooted, if you manage to run it, set AP and MTP+ADB to see phone as disk in windows, this helped me, hope it will help you.

It is the USB cable I had the same problem and changed the cable twice

Is it fast charging? Mine won't connect on any PC and also won't fast charge. I guess it's a damaged usb port..............

I have this same problem. My phone is not recognized by computer or any program. I was trying update TWRP and now i have samsung logo loop. Before i was updating i have sometimes problem with fast charging and computer dont saw mass storage when i connected phone
I changed completely module with usb in S6 but this dont resolve my problem. I used 3 different cable and changed USB port. I tried with windows XP and win 10.
any suggestions what i can do to bring to alive my S6?

Same problem here, started after updating to Marshmallow.

Exactly same problem with my s6 after 6.0.1 update! Sometimes phone will charge but it wont connect to pc/otg wont work but when i play around with MTP+ADB in *#0808#, s6 wont charge but instead it will be recognised by pc that usb connected not recognised and otg will work!!!!! always vice versa. right now my battery is empty and still wont charge!
---------- Post added at 08:13 AM ---------- Previous post was at 08:11 AM ----------
And looks like there is always a volt output through usb port and that time phone wont receive any charge

Really problematic.. I tried everything cables, drivers, different PC's and nothing.. tried my girlfriends S6 and worked instantly on my PC.
Only happened after official Marshmallow update,grounds for a return?

1. Power off your device (if it isnt already).
2. Connect to pc in recovery / download mode (just to trigger a response from pc /phone hopefully.
Do you know how to do this? If so, go ahead and proceed and see if the pc recognises your device in those modes
Let me know how that goes

Its not a usb port problem

Here are the usb drivers for those having issues. http://developer.samsung.com/technical-doc/view.do?v=T000000117
-Uninstall any previous driver relating to the phone (Also delete package if given the option). Disable windows Update aswell (Win10 Users). Also try install PDA+ from app store and http://pdanet.co/ to see if drivers will be correctly used.
-Make sure its a data cable, not a charge cable as only + and Negative wires are used and there is no way you can use a charge cable as a data cable.
-Connect phone and look for any pop up on screen, if anything pop up click it and see if it has anything to do with MTP or PTP.
-Still having trouble, reset firmware back to stock see how that goes, If not try boot into recovery and follow next step.
-- Once in recovery see if you can ADB push a rom over or a file, if that works then firmware is dodgy and something is missing. (Would recommend Android Tool kit to use this).
-- You could also try to install ADB insecure app ( Find it on XDA forums) and enable USB debugging and see if that will help
If you still can access file via usb when the phone is booted i would say to flash back to stock rom with ODIN and send it in for repairs. (Thats if you can get download USB mode to work)

Visited Samsung store, they said the USB port has failed but KNOX has been tripped some how, genuinely never rooted this phone or even attempted it but they showed me the warranty void status so basically even though they accept it's a hardware fault they won't fix it.

Quick answer for how I fixed this (sort of):
Go to "Settings" > "Developer Options" > "USB configuration". My phone indicated "charging". I selected MTP and my phone connected.
Why "sort of" - it reverts to "charging" every time that I connect the phone. I have to do the above all over again.
full history:
Same problem here. S6 on verizon network new in September 2015. Always connected without a problem to whatever computer that I have tried (linux & windows). The problem started after the recent complete software update on 2016-04-02. The phone is defaulting to "charging" and not trying to connect.
Go to "Settings" > "Developer Options" > "USB configuration". If "charging" is active, you know what your problem is. Select MTP (or whatever you need). The phone now connects and I can browse my files from my computer. The remaining problem, is that it reverts to "charging" every time that I connect the phone. Before the code update, there used to be a dialog asking me what I wanted to do (charge, data transfer, etc - sorry, don't remember exact options or how it was worded).
So, nothing to do with drivers missing on my PC. Nothing to do with need to install some other package. Nothing to do with a bad cable. Code was broken on a software update. (Or if you don't consider this to be broken, it was a poor software design decision).
!!! A CODE FIX IS NEEDED !!!

Galaxy Note 10.1 Table not recognized through USB

Hi Everyone,
My Samsung Galaxy Note 10.1 stuck on Samsung logo during boot. I cannot even go to recovery mode (power + volume up doesnot work). I can only go to ODIN mode. I downloaded odin tool and corresponding firmware from a website, but my problem is that PC donot recognize my tablet now. It doesnot appear as device or recognised by KIES. I reinstalled KIES (not KIES 3, although KIES3 is also installed on the machine to see but still getting the message "USB Device not recognized". Just to let you know that my 3 samsung mobile phones (S3, S4 and S6) are working fine and perfectly recognized by PC/KIES/Smartswitch
The tablet can be charged without an issue but it is not recognized at all by PC through USB. Looks like a dead end for me. Any help is highly appreciated as otherwise tablet was working fine until this problem occured. My tablet UK model is GT-N8010 and out of warranty.
Thanks
Fayyaz

Change usb cable.
Try another port
Try another PC

Download PROPER DRIVERS. Usually they are downloaded by kies but sometimes, they don't work. In case of that, you have to download samsung drivers by yourself. I think you can find it in here or simply google it.
Here is an another issue with laptops that I also encountered: When you plug in, despite you having drivers, pc doesn't recognize it or constantly the device connects and disconnects every 2 seconds. In that case, you need to update your bios version. However, this case is not likely.(If you are not bad luck brian like me) So focus on driver installation.

G920F, USB MTP, FASTBOOT not working anymore.

Hi all,
So I have a strange problem, a while back I discovered that I can't connect my S6 to my computer and or other computers, whatever usb cable I use the device is not detected at all. and only charging works.
I already tried more USB cables and validated they work with other devices, I also discovered the USB is not detected in fastboot mode, so I can't flash any images anymore over USB.
I also discovered that I might have flashed a wrong stock rom a few months back and I never tried to connect it to the USB in the meanwhile, when I trace the baseband version it says it's Asian..:crying: And this device is a dutch PHN. The device has ADB working over WIFI and root enabled, it also has TWRP installed and even there MTP is not working!
However i'm afraid there is no way I can flash a stock rom back to the device without a working fastboot, unless there are flashable zips.
What do you guys think?
- MTP does not work
- Fastboot works but USB is not detected (odin, device manager etc).. with all kinds of cables.
- ADB Shell + Root Works (Only over wifi)
- I got a full backup of all partitons, created it with TWRP.
- It's stull running android 5.1.1
Best Regards,
Toetje

I can´t belive it, someone who has the same problem then me. A little wierd is that I got 2 phones here.... Got my S6 which I´m using atm and some days ago a friend gave me a A5. Actually the A5 has exactly the same problem and one more problem is, that the "Home Button" of the phone is not working. No chance to root it at all.
It was like this.... I came back home with the A5 and first I thought about was rooting it. Restarted and tryed to go into "Recovery Mode" which wasn´t working, same as going into "Download Mode". So my first thought was that some of the buttons arn´t working. I was right, it was the home button which is without any function. My next idea was rooting over Laptop with Odin. Enabled USB Debbuging, connected a data cable..... and usb connection was not working... only charging!
After like a minute of trying and no success I wen´t eat first. When I came back i tryed again and USB Debbuging asked me to accept the Laptop. (Till now I didn´t thought about that it could be my first and my last time I will have a working USB connection.)
I wen´t into "Recovery Mode" thought about restarting cuz I wanted to go into "Download Mode". So I restarted and that was FATAL.... since then I had no chance anymore till yet to get a working USB connection. No matter which PC, Laptop, USB / Data-Cabel. And since the "Home Button" is not working, I don´t even know how to get Root.
Right now I´m asking myself if it could be a Firmware related problem?! I mean, when my friend gave me the phone there wasn´t the newest update installed on it so I just updated it. It´s a A500FU running stock Android 6.0.1 newest DBT Firmware..... and also I´m not able to change it without having a working USB connection.
Greets!

I ordered a new USB port board, will let you know the results!

Any results after changing the usb port?

Did fast charge still work for you? And this replacing the USB port work? I think this is related to a broken USB ic. For me replacing the USB port didn't help

Sometimes it's a bad charging port and / or liquid damage to the charging port.
If your home button clicks but does not work it could be liquid damage near the home button. Same goes for power and volume buttons.
I just fixed a S6 edge plus yesterday power button not working, liquid damage all around power button area, fixed burnt components and corroded pins.

Weirdest Problem i had on a Phone ever.

Hello,
I'm having a problem with my Unlocked Galaxy S6 (SM-G920F) When i plug the USB to transfer data from my PC, it only detects it as charging, and yes, i know i should change to MTP in the notification center, but i don't get that option, I've enabled it manually in the developers option, also enabled USB Debugging Nothing. Then I've rebooted to TWRP , still nothing. Tried connecting via ADB Doesn't detect it.(I'm sure that cable works , tried it with my Galaxy S5 mini , it works), So i went to Download Mode, Fastboot commands doesn't work , but weirdly it detects in Odin. Good, not great. I've decided to revert back to stock, flsahed the latest firmware. booted still nothing just says Cable Charging as if it is connected to a wall plug.
I don't know what do now .
Any help?

My S6 does a continues connected/disconnected loop on my laptop but on a desktop PC it runs great. Other phones also run great on the laptop so it's possible that you too have an isolated case.
A dumb suggestion, did you try clearing the cache? Try downloading Samsung Smart Switch on your PC and run the built in device driver reinstall function.

I personally think that it's a computer problem rather than a phone problem. If you flashed stock ROM only and didn't touch anything special it MUST work because we would have seen people complaining by now. I'm still holding onto the idea to check the phone with another PC. IDK, maybe you somehow blocked the phone on the laptop? (Download mode and "OS mode" are different things so that would clarify why the laptop detects the phone in ODIN mode)

I've tried hooking it up with a different working laptop , same problem. I even tried OTG Flash drive on the OS, and mounting it in TWRP no Luck.
