S6 Edge USB connectivity problem to PC (Only Charges no MTP) - Android Q&A, Help & Troubleshooting

So as the title states. I am having problems with getting MTP options while plugged into a computer. It sometimes works and others doesn't but it seems to work once on a first try on a new system and then the next connection it is only charging.
I was thinking maybe faulty port or cord. As I have tried several cords which also work on other phones I ruled the cord out. The port I have tried unplugging and replugging several times with no success, also jiggling the cord a bit while plugged in. No luck. It just randomly works fine once in a blue moon and then does not.
I have made sure my phone was unlocked, switching options in USB configuration setting though not the notification option because it is not there while it is not working, USB debugging on/off, restarting the phone, simulating a battery removal reboot, installing windows drivers, removing the sim card.
The phone is rooted with a custom rom for marshmellow. Can't really reset it or flash it without a computer to my knowledge. Was considering trying out Nougat but with the current situation I am not really able. Any help, ideas or insight would be greatly appreciated!

computer won't recognize phone

when i plug my phone into my computer, nothing. the phone pops up the notification to allow mass storage, but when i enable it the computer never shows the phone. i've messed back and forth with usb debugging, still nothing. is this sometihgn stupid i'm doing or what? I've even flashed a couple roms andstill nothing. help please?
its most likely the usb cable try a differnt one
that's what i thought, i tried two different cables (all i have are 2) and neither will work. Note, that when i use these two cables with the wall jack to charge they work.
do you have another computer? try it with another computer
or try a different usb port! or try installing mini kies that sometimes fixes the problems
Try rebooting and turning usb debugging off. Then plug up to pc (see if it installs drivers) then unplug, turn usb debugging back on and then plug up again. Should work after that.
OP-
A few days ago I posted regarding my similar issue (2-3 pages back).
I have still not resolved my problem, but that thread may give you an idea about troubleshooting.
Let me know if you figure it out.
For me, its most likely a phone issue & not a cpu problem.
I'm going to try cleaning my port with isopropyl alcohol later this afternoon.
You also might want to look at Callip's advice in the "PLEASE HELP" thread on this page.
wow, thanks for all the responses guys, i'll get to all this tomorrow some time and i will post my results.

[Q] Computer won't detect phone via USB all the time

Ever since going back to (downgrading in my opinion) from an AOSP ROM to a Samsung-based ROM, my USB connection to PC doesn't work reliably. The phone detects it is plugged in, USB debugging is turned on and I have the correct Samsung drivers installed.
But it's a crapshoot whether or not the computer detects the phone being connected. Sometimes it will work, sometimes it'll take a couple of minutes, sometimes it will require me to plug & unplug the cable multiple times.
It's highly annoying, especially since I had no issues with it whatsoever when I was on an AOSP ROM.
Any ideas?

[Q] Charging mystery. PCs no but detects. Wall yes. Cables, ports, pcs, oh my!

I'm asking for a solution to get my phone to charge via PC when phone is on. I've been troubleshooting this for days. I have a Sony Zperia Z Ultra, so the battery cannot be removed. This is what I've determined:
Phone charges when OFF and connected to PC.
Phone charges when plugged into wall.
Phone shows USB debugging is active when plugged into PC.
-If USB debugging is disabled, phone will not show any indication of being plugged in.
Phone's battery status is "not charging" when plugged into PC.
PC shows phone in device manager.
-Device manager shows yellow triangle next to phone name regardless of the PC I use (all of which previously worked fine).
-Have tried uninstalling and reinstalling drivers but all PC refuse to recognize the Sony drivers for some reason. I'm also at a loss on how to get the drivers installed properly, or how they got messed up in the first place. This happens for all PCs however. But regardless of drivers, the phone should still be able to charge once plugged in. It does not.
-If USB debugging is disabled, phone will not show up in device manager.
PC makes USB connection sound/notification when plugged in.
-If USB debugging is disabled, PC will make no sound/notification when plugged in.
PC will NOT show phone in Explorer (SD Card does not show up, nor can you navigate phone directories).
Have tried 3 different computers and laptops.
Have tried 4 different USB cables, both third-party and branded.
Have uninstalled recently installed programs (from both PC and phone).
Have tried resetting, rebooting, and hard rebooting phone.
Have tried cleaning the mini-USB port on the phone, it's nice and shiny.
Have used phone for about 6 months, problem just started happening about 2 days ago for no apparent reason, no changes were made on PCs (tried several) and especially not the phone itself.
Any ideas? I can only assume it's a phone issue from using above factors to narrow it down, however which phone factor should I focus on?

Honor 7 PLK-UL00 and B341 Device not recognised and its only charging

Hello all,
Honor 7,
PLK-UL00
B341 and EMUI 4.0
Android 6.0
Im unable to use my phone as USB Mass storage device. When i connect my phone to PC sometimes im getting as USB device not recognized and sometimes im not. I tried different PCs and different cables. ITs ONLY CHARGING
tried cleaning the micro usb port, uninstalling and reinstalling drivers in Pcs but it didnt work.
I switched off my phone, removed mem card, reinserted it, swithced it on again, connected my phone to PC(in sleep mode)
phone is detected as storage device and got notification in notification panel to select as charge only/files mode/ photos mode.
After ejecting and removing cable again back to issue. No detection. OTG also not detected. No Data transfers are being made but its only charging( even through Car USB port)
Anybody facing USB not recognised problem ? i hope its software related.
could anyone let me know of solution.
Thanks.
I am also facing the same issue
I thought I was alone in this issue.
Basically, my problem is, the wall charging and USB connect are reversed. i.e., I connect my wall charger, its showing as USB mode and when I connect the cable to a PC, its showing as AC Charging. I tested with Ampere app and when I connect to AC Charger, it is drawing only around 300mA(like it would do if connected to USB) and its drawing around 1.5A(like it would do when connected to wall charger) when connected to USB PC.
I have been having this issue for quite sometime and recently, I had upgraded to Marshmallow through OTA upgrade. I thought atleast this upgrade would fix this issue but I am still facing the same issue. I even contacted the customer care and nothing useful advice other than restoring to factory settings was suggested(which I tried and didn't work).
I guess it should be some software issue but don't know what it is or how to fix it. Any inputs would be welcome.

sm-n920a error when plugged into computer

I've tried everything I can find on the web to repair this sm-n920a. Any time I plug it into a computer it comes up with a usb error.
I've even replaced the charging port, with no luck. It charges fine, doesn't appear to be any damage, tried 5 different usb cords that are working fine with other phones.
The ultimate goal for me is to update it to nougat, but the ota won't push on it from at&t, and obviously I can't force it to update plugged into the computer.
This even happens in download mode.
This happened to a lot of these phones, the ultimate real fix it seems to be replacing the mobo, but would like to know if anyone has any real fix, or a way to work around it to install nougat. I've tried a dozen things to get it to try to push nougat too with no luck.
Since these phones dont even have an sd card I can't even load files onto it unless maybe by bluetooth?
I wonder if I moved nougat over to it by bluetooth could I then get it to install somehow?
I just verified it's definitely something wrong with the phone cause I can insert a usb dongle that I have and a usb drive which comes up fine on my note 4, but doesn't appear on the note 5...although the light on the usb drive turns on, but it just doesnt see it...so there must be something wrong with the drivers on the phone, or something on the phone end...any help would be appreciated.
usb host check shows usb host not enabled on the phone. Can only "fix" it it appears with root, can't root without usb access.....daaaammmnnn
