Galaxy S7 failing to charge wired or respond to usb input on pc - Samsung Galaxy S7 Questions and Answers

Having a few issues with an s7, charge port has been replaced (twice as I sent one back thinking that was at fault), charges wirelessly ok but not wired, now I need the wired to connect to pc to restore the phone through Odin.
Any clues, starting to wonder if it's the main board at fault, any wireless methods for connecting and using Odin, phone has a tied account and the gmail acount it's tied to is not known hence needing wired connection to use Odin.
Tried many chargers and cables.
Thanks in advance

mmm i am not sure, but my s7 looks like having the same issue.
tryed to use different cables and restore factory settings. did not work.
so the only way is use external sd card

Currently facing the same issue, but i think i messed with my charging port quite a bit. Now, i can only charge my phone using wireless charging, and i can only transfer files using the external SD card. :/
Very Sad,,,,,, I still have not tried sending it in for repair as i fear that it wont be waterproof anymore. Dont want to risk it.

Do you have any idea about how to make root without cable? I have tried all the one click apps

mmm i wonder, may you tried to install supersu or anything like that trough the default recovery mode? and then install twrp with the app?

open the back cover look on the left under the board there is a connector that plugs in from the usb .
it plugs in from bottom up

Yep that plug just near the antenna and home button flex is firmly home.

Then the only thing I can think of , is hardware problem , you need to replace the USB pin.
( Did you try the old needle in the charging pin trick to remove any dirt inside )

Replaced the charge port flexes which include the usb header twice now.

You say you've tried many chargers and cables, but have you tried a new Genuine Samsung USB cable? I've seen many people on XDA having problems with cheap 3rd party cables when Genuine works fine

usb connection with pc suddenly dead

Hello suddenly my nexus s stopped connecting with data with the pc it only charges, tried with 3 diffrent computers with diffrent os , no menu popping on nexus and nothing connected on the computer(like i didnt connect anything), i removed the battery left it for some time installed stock rom still nothing.It was acting normally for a second and the other it stopped any help appreciated!
Are you sure you're using the cable that came with the phone? I have an LG Wink featurephone here that uses the same connector at the phone end -- its cable will charge my Nexus S (using the computer, obviously, but also when used with either the LG or Samsung charger) but no USB connection happens when I use it. Only the cable that came with my Nexus S provides a USB connection when I connect to the computer. I guess there are pinout differences between the two cables.
If you're sure you're using the right cable, I would guess that it's gone bad if it doesn't work on any computer. You can buy an (overpriced) replacement from Samsung or maybe a cheaper one on eBay or at a retail store. If the latter, be sure the seller lists it as compatible with the Nexus S.
it happened with the original cable ppfff i dont know...
same problem

Hi
I have the same problem
I have no idea what the problem could be.
We are not alone with this problem: code.google.com/p/android/issues/detail?id=13553
Now installed stock rom as well but still the same problem.
If i starting the NS in the bootloader mode the phone is not recognized by the computer.
It would be great, if someone knows a solution!

I've been trying to get help with this for weeks. No one is even responding to my posts. I thought it was something OBSURDLY simple, such that people didn't even want to waste their time responding to me.
Seeing same problem, No connetion via USB
Posted problem in General,, http://forum.xda-developers.com/showthread.php?t=1104245
Tried different cords, different computers and operating systems,, did cold start several times on phone (removed battery) still no luck, I am running totally stock
Curious do any of you have the Google Music Beta?? (maybe a over zealous rights thing?)
just tried it with a Win 7 machine that had never seen it before and it said it could not recognize the device,, me thinks that the MS device driver DB is messed up buy some recent Win update??
i sent it to samsung to change my usb slot because after connecting to pc and nothing happen when i went to charge the phone it took 5 hours to get to 30% so iam almost sure that mini usb slot malfunctions

My phone charges just fine. And my USB connectivity was fine until I manually installed 2.3.4.
~I had usb connection problems after upgrade to 2.3.4 a bit different but I managed to get the USB back by formatting the SD card.

I was on 2.3.3 when this happened, i tried to flash 2.3.4 then and again it didnt work but the strange thing is that when i was moving the mini usb the first times up and down it was shown for a moment as a broken usb device.Then this stopped and was not shown at all on the computer and finally the phone charged super slow when connected to electricity
Beginning to believe that it is a physical prob with USB connector on phone. It seems to start/stop charging when wiggling usb on phone but no mounting. Doe anyone know best way to resolve , T-mobile but bought from Best Buy? so to Best Buy? FOR SUPPORT /EXCHANGE? suggestions?
I've seen loose connections before. My suggestion ain't the cheapest but the plug, on the cable end, shouldn't wiggle. I went to a corporate sprint store, the ones that actually have working display phones, and got their usb to micro usb data cable. The thing with that cable is when you plug it in the phone side, it goes into the jack firmly. You can almost feel the little locking tabs click into place. There should be no play or wiggle with that cable as long as there's no damage or abuse with the jack on the phone. IMO, that's a good data cable. It's never given me problems before.
Also, sometimes the cable is only wired for charging. A true data cable will be wired correctly and be able to both charge and transfer data. Usually the cables that come with the phone are crap quality. I don't know if my suggestion will help but it won't hurt to have a good cable for data transfer and flashing. The last thing you want is a flaky connection from a cheap cable when you're flashing roms. Russian roulette with bricking a phone in a worse case situation.
Did you try reboot the computer and the phone? How about a different usb port? How about unplug any other usb device in case it's conflicting for some unknown reason? It sounds like so many people with windows 7 are having problems. Usually always happens with a new os that's released. Xp, for flashing devices and programming different hardware devices, has never given of a problem. I have a small partition with xp on it just for that purpose only.
off to Samsung for repair for me...
After time on phone with them and a factory reset belief is that the usb connector is defective. BTW Best Buy just hands off to Samsung 1-800 #
So Back to a barely functional G-1 for a while, glad I could find it!
So is Samsung or the carriers replacing or fixing units?
My USB data died shortly after 2.3.4 ota update.
Wifi FTP is fine for data transfer but I want USB debug to work...
Shame on google and Samsung, this bug has been around for months.
no shame on anyone...
I went through a factory reset with Samsung on phone that isolated the problem to what is apparently a loose usb connector, nothing to do with software... only hassle is sending it in for repair, as` mentioned problem needs to be dealt with Samsung customer service (not carrier or Best Buy), they were fine on phone...

USB port seems to have a bad connection... can i return for a free fix / replacement?

I have had a UK SII since launch (originally on O2) but rooted and now using CM9.
Ive noticed recently that my charger needed to be wiggled a bit in the port for the phone to start charging.
Now it seems to have gotten worse and now i have to have the plug tilted in the usb port at a certain angle and apply pressure to it for it to start charging. Ive tested with 4 different leads. Connected to my laptop and phone keeps on flicking to usb debugging message so i am presuming the connections in the usb port are faulty.
Ive also cleaned a load of fluff out from it and its still the same.
The phone is just under a year old... so im hoping its covered for a 2 year cover like my old Sony Erricson phone.
Do you think they will repair this fault or make me pay due to excessive wear n tear?
I charge once a day over night, and dont use the port for much else apart from probably undre 20times connected to laptop.
Thanks
did you try the cable with something else than your phone? It looks like it's probably some broken part of the cable inside, but try anyway.
If it works fine with everything else it's your phone, if doesn't work with other things it's the cable and i'm not sure if they would replace it, because it could be your fault if it's the cable.

[Q] usb otg cable doesn`t work

I had my 7.7 for some time and about 2 days ago i've bought a cheap chinese usb otg cable from some shoup around here. I thought it would be as simple as pluging it in and connecting some usb stick like i've done with justabout all usb otg stuff i previously owned. But it doesn`t do anything. I`ve tried other usb devices, the tab simply doesn`t power them at all. I`ve also disasembled the cable and measure it, everything is fine. I`m on stock ics 4.04, also tried a couple of kernels, it just doesn`t work.
Has anyone encountered such a problem.? Damn weird....

errrr....I think I misread your issue and specific item...
sorry!
Still great though!
The usb otg cable is just a plain simple usb cable with a 20kilo ohm resistor placed between 2 pins on the galaxy tab 30pin connector. That's about all the things inside the actual cable. When you plug it in, the tablet should figure out that the 20k resistor made contact with the pins and an accesory was connected. Mine doesn't. The cable is fine, i think there's something wrong with the tablet. Doesn't it supossed to power on whatever you insert on that usb port? Because i can't get those 5v on the port.
I don't know if it's a software or hardware problem....

what file system is your USB Stick using? try formatting the stick to FAT32 and see if its a file system issue
have you tried using another OTG cable? I'm also using a china knock off bought for 4 bucks, running stock ICS and it detects most of the thumb drives I attached to it
thanks for the replies but the situation is kind of different in my case.
In order for the tablet to read what kind of filesystem you have on a usb mass storage device (stick, hdd, whatever) it must first power it on and then attempt to access it. In my case, it simply doesn't power on. So, it doesn't matter what kind of file format it has. Also, if i plug a mouse/keyboard, it won't work either.
I thought that maybe it's a broken wire inside the connector, so i took it apart and measured each pin. The otg adapter is fine, it should do the job. I've also tested on another samsung tab and it worked straight away. It seems there's something wrong with my tab. However, other then this, the 30 pin port on the tab itself seems to be working fine.

Help figuring out what's broken with my OnePlus One

Hello everyone,
A couple of weeks ago my USB data connection on my OnePlus One has stopped working.
This means that no connection is even detected on any computer.
This is not a driver issue as the computer doesn't even notice anything has plugged in.
I think it's not a software/ROM issue because the same applies to fastboot mode and recovery mode - no data connection, no "usb plugged in" sound on any computer, no device showing up.
It's also not a cable issue, as the same cable works on other OnePlus One's and I've tried many different known-to-be-working cables.
More facts:
1) When plugging to a computer USB port - the battery icon shows the charging (lightning) symbol for a half a second and disappears and it won't charge. The computer, of course, doesn't see a usb device plugged.
2) When connecting to an AC charger - it charges just fine.
3) I already tried replacing the dock connector and flat cable unit with a new one - did not solve the issue, which means the dock connector is fine.
Any insight on this will be greatly appreciated!
Thanks!

By dock connector, you mean the USB port? Typically, this issue arises when the pins in the USB port get damaged. I don't know how the rest works out, but if that particular section of pins have to communicate throughout the rest of the motherboard, perhaps the trail responsible for that may have somehow gotten damaged. This is a clueless theory, someone with more electrical/motherboard experience can verify this.
What I do know is that once the micro USB port has been replaced on the phone, the issue should be fixed. It happened to an S3 I still have and I got it replaced by a friend. Sadly, it happened to me at the wrong time since i had wiped the entire OS and internal storage and was relying on my USB OTG cable and a flash drive which contained a rare rom called Sonic Open Kang Project (SOKP).
DO NOTE that this has also been an issue with me on the software side of certain devices. I uave had practically every flagship device out there and have come across a point where this happens on both stock and custom roms. My Optimus G did it on custom roms, and my Nexus 7 2012 occasionally on stock. There were other devices I cannot remember but sometimes factory resets or replacing the rom helps. However, you did state that the result is still the same on fastboot/recovery, so this seems to be more on the hardware side.
I replaced the USB connector (including it's flex cable) entirely. Did not solve the issue.
What else could be wrong?
try again

I tried a lot of different computers and cables. None of them detect a USB connection.
Again, to clarify - they don't even SEE a usb device has been plugged in.

You running a custom recovery? If so, see if you can toggle the mtp on/off reboot with each back to recovery. Use the tools to check the filesystem, permissions, etc.
Could pins have damaged?
Well, I did replace the USB connector with a new one, so if pins are damaged it's gotta be on the motherboard side, and I can think of no reason why that would ever happen.
As for recovery, I'm running TWRP and I'm not sure I understand what you meant I should try. Can you elaborate?
Thanks

Malfunctioning USB port. Trying to root but can not connect to cpu to flash

To start off my USB port seems to be malfunctioning. I can charge but will always get the " charging slow" error. It will even charge via usb port on a pc but it will not recognize it as an external Storage unit. Ive changed the usb settings via developer settings. However i do not get a usb notification on my phone giving me the option to switch the function.
Is there a way to connect to a PC to use flashing tools/ADB in order to unlock my loader as well as flash and send commands to my phone. I can use LG AirDrive but i do not believe commands can be sent through that. Would greatly appreciate help since im lead to believe rooting has just hit for the Stylo 4.
If it is any importance. I am on the stylo 4 bought through best buy not attached to any carrier Q710ULM is my model number
Did you try another USB cable? Ive had several that broken inside and the same happened. Changing USB cable solved it
Ive tried several. It is definetly my USB port. I think dollar store chargers did it in. And now since its always slowly charging i think it won't do any data transfer maybe in fear of loss of data due to bad connection?

Yours is a micro USB port right? Most likely it's a faulty USB port. See if you can get a store to replace it
Yes. Well a Type C but android charger none the less. I guess id have to send to LG to honor the warranty. I didnt purchase ot from a carrier and also did not get aj insurance plan when i connected it to t mobile.
In other words you are saying im SOL for getting on ADB? Atleast until a one click root has a method for this device.
Just to test. Did you test in another computer to see if it is detects it?
My computer corrupted the adb connection due to faulty drivers. Reinstalling windows fixed it because in another computer that i have it was detected normally. It's just to test the whole scenario here. If it doesn't work RMA it to LG
Yes I tested it on a computer as well as multiple outlets. I finally just took the back off and took out the port. It had a lot of corrosion around it. Almost all teal colored. I blame those dollar store chargers. I have no other explanation behind why it happened. Either way there is luckily someone wihtin range selling a bunch of parts on offerup so I was able to pick uo a new port for 7 dollars off of him. When I removed the back I was pretty surprised to see how the "non-removable" batteries are packages in there. Just a bunch of layers wrapped up in thin plastic with some tape around it. haha
