S4 USB Won't Connect - Galaxy S 4 Q&A, Help & Troubleshooting

So my S4 will plug into my Mac Book Pro and will charge, however it won't go into debug mode. I tried wiping it with no success. And yes i've quadruple checked that debug mode was enabled. Any thoughts?

[q] debugging mode

I am trying to use my rooted galaxy s5 sm-g900f in debugging mode, and when I enable the mode it works for 5 second and than reconnects to the pc not in debugging mode. the option stays ticked but if I go back and getting in developer options again it isn't ticked. it is not a problem with the computer because it happens even when it is not physically connected with a cable.
Thank you for helping

USB doesn't work after OTA

Hey all,
I have tried to google and figure this out but my phone doesn't show up in device manager in windows or in android file transfer on mac EXCEPT when in download mode or when the phone is off/charging via my computers USB port.
So when in download mode, the phone shows up in device manager....
When my device is off and charging via USB port, it shows up in device manager...
I have tried USB debugging mode no change...
Charges just fine. No usb port issues because it connects during download mode etc...
During these times, i obviously can't access the SDcard.... but as soon as the device boots, it disconnects and disappears from device manager even though its still charging etc...
This only happened after the last OTA update.
I assume i will have to restore to defaults as its probably an issue with the kernel and usb protocol but I dont have the phone rooted and i don't want to root it at this time... I am hoping there might be a quick fix and/or setting i am missing.
Thanks!

You do have to have USB debugging mode checked. If you don't have the developer option enabled in settings, go to about phone, find your build number and tap on it rapidly until it says your developer option is enabled. Back out and you should see a developer tab. Click it and make sure USB debugging is checked. If that doesn't work you might reinstall the latest USB drivers.
i did both of those. the odd part is when in download mode windows chimes that my device it attached.. no problems right? but anytime the android OS is running no chimes at all no recognition at all on any computer... its almost like back in my linux days when the kernal had a usb module failed to load... i swear its as if the kernal turned off usb data communication... power is fine... just wont communicate unless in download mode or in a power off state.... totally weird...
When you plug it into the computer, pull down your notification drawer, make sure USB setting is set to MTP. It usually is set to installer, or charge only by default.
Also I'd say completely wipe out your phone drivers on the computer, and reinstall all new ones.
Possibly reinstall ADB as well.

Computer won't recognize device

I just got the 6P on Amazon, used-like new. It has 6.0.1 with TWRP installed. When I plug in the short USB-C cable into my W10 PC, it doesn't detect anything. So I go enable debugging mode, turn on USB-Debugging and go down to "Select USB Configuration" and it is set to Charging. The problem is that it won't let me select any other modes other than Charging. It does charge when it is plugged in so the cable is working in some aspect. W10 device manager doesn't show any new USB device or unknown devices when plugged in.
So I reboot into Bootloader and Windows still doesn't detect any device. I tried all the other USB ports. So I'm not quite sure how to get this device to connect to the computer or to just get it to factory stock.
And in TWRP, the log shows MTP enabled and Windows still doesn't recognize it.

Pc not detecting android but charging

Hi Basically plugged my S4 i9505 in via usb. Nothing shows in my computer, but phone remains charging. I have tried uninstalling and reinstalling all samsung usb drivers but it does nothing. Tried installing kies/older usb drivers, still no luck. Regardless of if there are drivers or not on my pc, there is no detection what so ever. My pc is detecting my second S4 I9505 perfectly. Anyone know the solution to this?

Tap 5 times buildnumber in settings menu under: about phone to open developer settings. Enable USB debugging. Now you can choose what to do when phone is plugged in pc.

USB debugging is Enable still nothing happen
USB debugging is not required in order to have the phone recognized by the computer.
Have you tried different USB cables and USB ports? Is the phone detected on other computers?
i had the same problem.... and we found out that the pins or the usb connection sh1t from the phone doesn`t make good contact. si try to push a little but or force up and down the usb cable to the usb from phone maybe you will manage to find a stable connection or something.
when i connect to phone to the pc i have to hold the usb cable connected to the phone in a weird position. that works for me

adb mode not work in ng

So I have tried and tried to get adb mode working on my Galaxy s8 with no success. Is there anything special you need to do first to get your computer to see your phone??
Have you enabled usb debugging in developer options?
If the above poster didn't nail the problem then 9/10 times the issue is with either the USB drivers on your machine or a bad USB cable
I ended up getting it running on a different laptop. Worked right away. Seems my original laptop doesn't recognize the Samsung device, even with the drivers
