USB Connection always on/off, factory reset not he - Galaxy S6 Q&A, Help & Troubleshooting

Hello,
I have a Samsung Galaxy S6 (A1 Austria branded) Android 6.0.1
When I connect my phone to my Laptop, the connection permanently goes on/off once per second. The windows10 connection notification and also in smart switch are permanently blinking, like.. because it connects - fails - reconnects - reconnects-reconnects...
I tried with different cables. already did a factory reset, but the problem persists.
USB config is switched to MTP
Does anybody know how to fix this please?
Many thanks in advance!

Did you try another PC?

Ah, yes, sorry, I forgot to give this info - with my Desktop PC in Win10 it works, but not with the Laptop...

MDR-1ADAC issue

Hello!
I was using my Sony MDR-1ADAC heaphone with Xperia cable via USB port on my Z2 and never had any promblems.
Now on my Z5 nothing worked. The phone did not recognize the headphone via USB port and with Xperia Connection. Has it something to do with the DAC (the Z2 had not one)?
Any ideas?
You tried Settings/Device Connection/USB Connectivity/Detect USB Device?

Tell me what does screen show when you plug it in wall socket, just low battery with lightning logo on top of it, and it stays there for about 4-5 seconds and it resets and does the same thing? Basically its looping death of battery. If you have that I can help you
Did you try the reset button which is near the sim slot? Keep the reset button pressed for like 1 min then try connecting it using Flashtool. Flash mode of course.

Cannot Flash 6.0 Firmware via Flashtool

Hi! I'm trying to manually update my phone to Nougat by flashing a 6.0 firmware but I'm not successful. All I get is a blinking green light and that's it. I've tried uninstalling/reinstalling the flash drivers, doing software repair via Xperia Companion, checking that USB debugging is enabled, but still nothing. I was wondering if anybody here has had the same experience as me.
Check the USB driver

Use a different USB port. If you're using a front port, try a back one. Even better, use a USB 3 port. I had the same with my front USB 2 ports, worked fine on one of the 3's.

try disabling driver signature enforcement on windows startup page, win10 and win7 have different ways to disable this, look over google and try that it might help:fingers-crossed:
okay, i did another software repair via companion and that did it. finally on android nougat. thanks to everyone who responded!

laptop can't detect OnePlus 6 in adb/fastboot

I'm trying to unlock the bootloader of my OnePlus 6 so I can root but my laptop can't recognise my OnePlus in cmd prompt. I tried uninstalling and reinstalling the drivers and even a rooting tool that I got from XDA and nothing is working, can someone help me? (I'm fairly new to rooting)
Did you enable usb debugging?

See if you can find your device in Device Manager. If it has an yellow triangle on it you need to install adb drivers for it.
Change USB port - It helped in my case.

Mee too. Im unable to recognise the oneplus thorw the fastboot mode... if i try to type fastboot devices nothing appened...Can someone help us? Thanks
Did you both checked "allow USB debugging" under developer options and actually allowed it after connecting to USB port, it it didn't appear on your phone?
Wysłane z mojego ONEPLUS A6003 przy użyciu Tapatalka
As mentioned, make sure you've enabled Developer Options, then through there, enable OEM unlocking and USB debugging. Is the phone booted into fastboot mode (bootloader) when you're trying to find it via the command line? If you're booted into the system, fastboot won't work. Only adb will.
Another thing that might help is to use a Mac if you have access to one. There's no need for drivers, so that problem is eliminated. Connect via USB and the command line should work. (This is not a PC vs. Mac thing; it's just a practical matter.)
Solution
I had the same issue and the solution for me was to reinstall oneplus drivers the updated ones from the oneplus drive that appears when you connect the device.
As far as I remember, you can check devices with ADB devices not fastboot devices.

You can check with both adb and fastboot with the devices argument.
Code:
adb devices
fastboot devices
Same here
But my laptop can reconize my phone on fastboot mode
What OS? If it's Windows 10 N version, then you will need to download the Windows Media Feature Pack.
-Download latest OP6 drivers
-Enable Developer Options
-Enable USB debugging in developer options
When the phone is booted, you can use ADB devices commands, however, when in the bootloader, you'll probably have to use Fastboot devices.
On my phone, ADB devices never works at the bootloader, only outside of the bootloader.
I had an issue where every time I wanted to connect to fastboot, I had to turn off USB debugging, plug into my computer, wait for it to recognize, unplug, enable USB debugging, and reconnect to PC. Might be worth a shot to see if it's the same issue.

Doing this and enabling test mode on W10 LTSB before reinstalling the official OnePlus drivers worked on my OP5T (OOS 9.0.5). I had the same issue the OP described.
What can I do if the phone is locked and is in bootloop? I can't go and do the oem unlock and allow unlocking options in settings as phone is already in bootloop.
