[Q] N910C USB connection interrupted repeatedly - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello guys,
Recently I flashed the lollipop firmware and didn't like it so, I flashed 4.4.4 again to my N910C and rooted.
I can't use USB connection normally now. When I plug my phone to my laptop, I can see and edit folders of my phone for 10 seconds, then the connection interrupts and re-connects. This process repeats and doesn't stop.
I already tried *#7284# and *#0808# processes but they fail all the time.
How can I solve this issue?
Thanks.

I solved I guess. It was because of my laptop, don't know why yet.

[Q] Phone auto restarts when connected to pc

Hello! I have a major problem. After flashing back to stock, my phone suddenly cannot connect to the pc at all. Once I plug in the cable the phone auto restarts and is stuck in a bootloop until I remove the cable. It also doesn't charge if connected to the charger. Any ideas on how to fix this?
More info regarding this case. Phone is an lg d802 32gb model. Reverted to stock from cloudyg3 rom. Right now I cannot access download mode as the phone auto restarts once I plug it in the pc. Tried with 2 diff pcs but the same problem.
hmmm

Try changing the usb cable.
Hi, I tried 3 diff cables but it still has the problem. Also, I think the cables are not the problem as those cables do work for my other phone (both in charging and connecting to pc). This is a really weird issue. Anyone else experience this?
I have the same problem, phone restarts when connect to pc, if you connect and disconnect several times the usb cable, sometimes it works, you can try this to access your phone, turn it off, connect usb cable, and the power off, sometimes it work for me, also to charge the phone.
Anyway if someone can help us.
Thank you.

[Q] Device not recognised via USB cable after Lillopop update

Hi folks,
I've installed german update on my Note 4 and from that moment I cannot get my phone to be recognised on any computer (Mac, Windows). I tried with Kies, without it, using only Android File Transfer.
Nothing. Phone starts charging but nothing else is happeing.
Am I alone in this or is it common issue?
Cheers,
Ralph

Do you have the latest drivers of samsung ? Did you make full wipe when you updated to Lollipop ?
When you plug it up have you made sure it's in media mode and not camera mode?
Sent from my SM-N910P using XDA Free mobile app
My problem is, once cable is connected there's no message or option in notification panel. Just one vibration and charging starts.
There isn't an option in main setting either so setup usb behaviour.

Cheers mate but yep I tried that and nothing changed
I'm in the same boat. Had this problem for a long while, almost had my guarantee expire so I had it fixed. Not sure what caused it, or what fixed it. But couple of weeks later I was transfering some files through the now working USB port and accidently touched the cable - the device lost connection mid-transfer and since then I was unable to use the USB to transfer files, or connect the device to anything but the charger..
Along comes the 5.1 OTA which I decide to install and mid-install there was an error and the device soft-bricked - I can't boot it, it shows the Android robot with a red traingle and exclamation mark and 'No command.' written under it, at which point it reboots after a couple of minutes.
I can access recovery and fastboot mode and excecuted a factory reset but to no avail. Does anyone know how to fix the USB so that I can reflash stock and make my device work again?
Also, any ideas if one could bypass the use of the USB port in fixing the softbrick would also be helpful.

A800i USBsettings has stopped

Guys could anyone help me?
My phone is Samsung A8 variant A800i non-rooted and already 6.0.1.
Eversince I upgraded to MM thru ODIN I am encountering an error in my OTG as in it won't read any disk... the only resort to make the otg work again is to reflash my phone. However during the most recent otg failure, a "USBsettings has stopped" was shown. I factory reset my phone but still this notification appears everytime I start my phone. So when I decided to reflash my phone, I was shocked that my laptop only charges my phone. It can't even detect my files thru mtp connection.
I tried the following and my laptop still can't detect my phone:
1. At the Developers Option I tried to switch the USB Configuration from MTP to Charging to MTP and various other switching, while connected and unconnected to laptop.
2. Dialled *#0808# to reset USBsettings but I am only getting "USBsettings" has stopped.
3. I reinstalled the USBsettings.apk from the system folder (via total commander).
4. I have installed USBsettings.apk taken from another phone.
By the way before I tried the above methods I have already eliminated the cable and pc problems since using the same cable and laptop, I can connect my other samsung phone thru mtp and is detected by odin. I have also tried various other desktop on Windows 7 and 10 but still the same problem: these only charges my phone.
Moreover, there is no abnormality in my charging time eversince this happened.
Hope someone could help me make this work again.
Thank You.

Issues with USB connections on newest Oxygen OS

Hi,
since one of the latest Oxygen OS updates, my OnePlus 5 is not able to connect to any PC anymore as long as USB-Debugging is enabled. It's not showing up in Device-Manager nor lsusb on multiple PCs, I've tried rebooting multiple times, safe mode, clearing settings data, but nothing seems to have changed it's behavior - when turning on USB Debugging, all USB connections seem to get lost, including data and charging. A curious thing I noticed is that the Android-System notification that lets you switch USB modes sticks around when unplugging in this state, even after disabling debugging again, until the phone is restarted.
Is this a common issue? I haven't been able to find anything about it on XDA or on their official product forums which seem to be pretty dead, but it's a pretty big problem for me since I need this phone for app development.
Thanks!

I'm running the current stable Oxygen OS 5.1.5(ONEPLUS A500_23_180808), unrooted. I'll try installing the new beta, since fastboot mode still gets recognized by PCs.
Ok, so beta 19 didn't change anything about it - still the same issue and behavior when unplugging. Not sure what else to do other than trying to wipe it, which would be pretty annoying
I have the same problem and I can not solve it neither with usb debuginc or mtp and I see that Oneplus is not bothering att all about this problem. I need to transfer some data from my computer to my phone and I am stucked. I am thinking sending to warranty or sell it! I was a big fun but now........

I've tried this a few times, the options in that pop-up don't have any effect whatsoever after enabling USB debugging and unplugging/plugging the phone back in. Also tried changing the default setting, which doesn't seem to have any effect either though.
Same for me. No effect att all. I don't lnpw what to do. I have a lot of files in storage and I can not root my phone and try another Rom.
Help!!!
I have done all the possibel combinations.
