USB Mode

Hi,
So I've been trying to get my NS to connect with my MBP. I'm not having any luck. When I connect the USB to my MBP nothing happens and on the NS I've read there should be a USB mode but it doesn't appear. I know its connecting because the NS does charge, but how do I go about transferring files?
Thanks

Works fine for me on my mbp. Plug in, and turn on USB storage through the pull down notification bar and you should see the drive on your desktop.

I've tried that, but when its connected nothing appears on the notification bar on the NS. I don't even see anything mounted on MBP. I can tell its connected because its charging but I can't connect.

Do you guys think it could be the USB cable itself? It allows for charging but it won't detect the storage device.

Its a possibility. Are you using the supplied USB cable? Ive had problems connecting my ipods before due to faulty USB cables.

I'm using a cable that I have for me LG phone. I bought the phone of Ebay, and never got the USB cable

Most likely USB cable.

Okay so I tried the cable with my old phone, it would only charge. Then I put in the SD card and it went into storage mode and showed up on MBP.
This is not happening with my NS. So I doubt its the cable.
Any other suggestions?

Try using different port on the MBP?

I would still try another USB cable. Not all USB cables are made equal. You would be surprised. Borrow a friends. Otherwise try factory clearing or going back to stock on your device if that applies.

I just bought an OEM cable from Ebay. Hopefully that will work. I also reset the phone, tried erasing USB mount no luck.
This isn't a big deal but I would really like to transfer some music from my iTunes.

Phone not being seen by any PC

So this issue started a few days ago. Any time I plugged my phone in it would constantly connect and disconnect from the pc. I've tried multiple usb cables, ports, and the 3 PCs I have with the same result on each. Now when I plug it in, it is no longer being recognized by the PC, Odin, ADB, etc... It will charge but that is it.
I have a warranty replacement coming to me however I need to be able to get this one back to stock... Any suggestions?
Before anyone asks, NO it has never been wet, dropped, damaged in any way, set on fire, caught in a land slide, earthquake, what have you.. The phone itself functions perfectly fine. All drivers are up to date, none of my PCs configurations have changed. I have one I use specifically for app development and not even that one will see the phone.

I had the same problem. I used a different cable and it all worked better....now with that said it happened again so I flashed my phone back to stock and all was well.
Then went to flashing ROMS.

Really check out the micro usb cable. A bad cable will just about always allow a device to charge, but data transfer is another story. If you really have tried a few micro USB cables, then it the problem relies elsewhere. Try restarting both phone and PC, and if neither works, sounds like you have a busted port on the Skyrocket.

Thank you both for your responses. I am a PC technician so I followed my usual troubleshooting steps to figure this out. I narrowed it down to either all of my cables are bad (not a chance) or the phone is just f**ked (likely). Ah well ill have to try to use another way to force the stock firmware and recovery on here. Lol
HTC = Hate The Consumer

I use my old Nokia OEM USB cable. Connects with the right number of pins on the USB connection end. I'd check your USB cables for # of pins . Skyrocket uses 5 I believe. Also that there is sufficient power to your USB ports. Aka avoid front USB ports which could only be 4 pin....

When you plug the usb cable in, do you see the usb icon at the top left of your screen? I have to pull that window down to tell it to connect to pc, then confirm it again before mine connects. Mine doesn't auto connect on its own.
I see you've been a member for a few years so if its not connecting, that really sucks man. Hope you get it figured out.

Not running the AOKP ROM are you? The R3 build had an issue with this, and all AOKP will disable USB to PC if you enable 'fast charge' under ROM Control...
Good luck :S

According to what I've been reading you can try using the *#7284# code and setting the USB portion from PDA to MODEM and then back to PDA and it would kickstart the connection. No dice for me though. Ive been through 7 different USB cables already.. I am not about to go and buy one just to keep playing with it my other phones connect just fine using the same cables. No, I am running the latest Sky ICS

[Q] phone wont charge or connect to computer with usb

ok. so i own a lg nexus 4 and sgh-t959v(samsung galaxy s 4g). the galaxy s will not charge with any usb cord nor connect to computer. i have tried new, used and old chargers, ive returned to pure stock firmware and still nothing. it will only work using the lg nexus 4 charger/usb. what is going on?

It won't charge or connect but it will go back to stock?
That's awesome. You probably have a broken usb connector.

It will connect to computer and charge using only a lg manufactured nexus 4 usb cord, so idk if that means its broken?

Help? Anybody?

Sounds like, from what you said, it works with that one LG Nexus 4 USB cable, it just doesn't like generic cords. There's nothing we can do to make your generic cords work. Hence no responses.
If it's still under warranty or a phone replacement plan, you can try to get it repaired for cheap. If it's not, you can either try to replace your USB port or, y'know, try different cables. Otherwise... pray that LG cable never dies. Sorry.

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

Try another computer. See if you can get any response from adb.

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.

recovery?

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

USB Device not recognized / No fast charge

So I've had my S7 for around two months now, and all of a sudden fast charging just stopped working. Thought, oh, must be using the wrong cable (have loads of them micro USB cables floating around)
Now I'm certain I'm using the official Samsung fast charge plug and cable that came with the phone, and still no fast charge. When I try to plug into my Windows 10 Desktop or Laptop I have a message that says the device can't be recognized
Phone has already been rooted and flashed with a custom rom. Didn't think that was the issue as it wouldn't even show the mounted storage in TWRP, or identify the phone in ODIN.
Now I've flashed back to the stock rom that I made a backup of when I had the phone, and I still have the same problem!! Can't access internal / external storage using the supplied USB cable and can't fast charge.
I'm thinking the USB port on the device is just knackard.. but really, I've looked after it so well I fail to see how this could happen, unless it's a common fault.
Might just get a wireless fast charger, but do you guys have anything else I can try before giving up on the USB connectivity?
Cheers

try to connect to a different pc, if same it means your usb connector is faulty

Sounds more like the cable is bad tbh, you won't get fast charge from a PC USB port, only from the Samsung charger
But if the device isn't recognised by the PC, and won't fast charge from the charger, the common thing between them is the cable
Possible it's the phone USB port, but more likely the cable is bad
Afaik certain cables can not fast charge either, so chances are the ones you have lying around that are not the official cable can not support it
Genuine Samsung USB cable is white with the USB port symbol on both ends and the phone end has two small ridges to grip when inserting and removing it, should help identify it

Yep I'm using the official cable and fast charger
I'm trying to fast charge via the fast charger and not USB. Only trying USB to access the internal / external storage.
Tried on my desktop and laptop and both have the same issue where my old HTC m8 connects without any issue.

To fast charge I've tried the original Samsung cable with the fast charge plug.
To connect to the PC I've used x3 different cables that all work with my HTC one m8. With all of them I get device not recognised. Already tried installing Samsung switch and reinstalling drivers which didn't work.

I mean for the HTC, does the Samsung fast charge cable work to connect to the PC?
Does sound possible the phones USB port is faulty if you can't get any connection at all to the PC with multiple cables
Try changing the USB mode in developer options
Networking > Select USB configuration

Yep the genuine Samsung cable works when connecting the htc to the computer.
I've tried enabling USB debugging and switching between charging, MTP, PTP, RNDIS, Audio Source and Midi.. all of them come back with the windows popup

Unfortunately it is starting to sound like the phone is at fault
Still under warranty? (KNOX 0x0)

Unfortunately not. Well it's been rooted and flashed so I guess not.
Ordered a wireless fast charger so hopefully that will see me through and WiFi network for file transfers.
I reckon the USB port will need replacing but I'm not really inclined to do that myself.

Just noticed you said you flashed back to stock using a backup you made
Have you tried stock using ODIN and 100% stock files, using CSC to reset?

My dad has a5 2016 with the same issue, and no warranty. I bought flex + connector , replaced it and still nothing. No fast charge ( it takes cca 4hrs to charge it fully ) and no usb connectivity. I gave up on that

@ClowsTyle
Any luck? I seen your recent post in another thread and it sounds like you tried to replace the USB but that didn't work.
I'm having the exact same issue now. Device suddenly stopped fast charging, Windows does not recognize it when plugged into PC. I ordered a new cable to double check and also tried on different computers. I also tried reinstalling drivers, but nothing has worked.

Hi my is doing the same thing no Fast charge and no pc connection, did anybody find out what happen with yours ?

You have to change power ic s535 for s7 edge.
When usb gets moisture power ic will damage.

I have same problem my phone charging 0-100 6hours but ı install notorious kernel and it takes 3 hours it is better than 6 hours

Same Issue
I've had the same issue for the past 3 weeks now and I've tried everything I know...
1. Tested cable and charger with another S7 and they work fine.
2. Factory Reset.
3. Changed the USB port chip.
4. Turned on "Low Battery Dump".
So far, the issue hasn't changed.

was this issue solved?
I´m having same issues whit my galaxy s7 active, I can not fast charge my phone no matter what cable I use, then noticed that evrytime I plug it to any computer it says the devicescan not be recognized, I´m about to buy a new charging port and install it, but I want to make shure this is not a software related issue.
I´ve tried several cables and several laptops/ pc´s
I´ve factory reseted my device and turned on low battery dump, wiped cache partition, and problem still there...

The charger could be faulty/damaged did you try a different charger?
---------- Post added at 06:43 PM ---------- Previous post was at 06:40 PM ----------
Dial *#08# and select the first option (mtp and another option i am on a custom rom that seems to not have the *#0808# setting

I also have the same issue with my phone the phone charges but not recognize and also tried to change settings on phone and nothing? And my other samsung phone works and nothing wrong with USB tried to install smansung drivers on PC and still same issue.
I tried a different USB and nothing works and different ports on my comp.
My ports works with my other samsung phone so not sure why not with the S7?
Is the USB faulty?
