Received a replacement device yesterday that is NG2. No big deal as I CF-Rooted it, then placed TWRP on it. Did a backup of initial state and went to transfer a rom to SD card and realized the phone would not connect
to PC as a device. Now I have 2 other S4's in the house and they connect immediately so it is not a driver issue with the computer(Win8.1), or USB cable. The 2 other S4's immediately are recognized by the computer.... I
have found that this one is recognized only while in Download mode, but when booted, nothing. I reinstalled the backup I first created and did a wipe 3x and I was able to get it to go into USB mode only 1x. The USB
icon appeared in the upper left of the screen and Kies recognized the device for the first time. After that I thought I was good so I went to the CF-Root installed Superuser app and opened it. It prompted about knox so
I ran it for knox disable. Bam, no more USB. What is going on here? I have rooted and worked with 5 or 6 different S4's with no issues. This is my first at NG2, and I want to point out that it is not activated yet as well.
Does not completing the activation trigger something? I am just trying to figure out if I should just return and swap for another. I have tried to reflash back to stock and wipe and it no longer offers the USB connection I
was able to achieve at the 1 point. This is an odd one and again, it is NOT drivers or the USB cable.....
Thanks,

Fixed. Returned the phone for another one.
Hey guys I tried to connect my nexus 7 to my Windows 7 laptop but nothing popped up it just showed as charging on my n7 I've tried update the drivers and different cables and different laptops too but it's all the same, even fastboot doesn't show up or mtp in twrp, any ideas how to fix this guys?
Anyone got any idea how to fix this problem?
Hey,
Have you tried enabling USB debugging in Settings > Developer Options?

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.

Do you twrp installed mate?
No, I do not.
Hello XDA, my virtual phone heros, i appreciate your good work, i am reading here for a few years as a ghost and today i signed up because i am lost with a serious problem on my Note4 N910C (English is not my native language)
THE CONDITIONS AND ENVIRONMENT:
My Phone was first running on stock Lollipop 5.1.1 when i rooted it over ODIN 3.10.6 with space X kernel and CF Autoroot, SuperSU then i flashed the latest TWRP...
After that i flashed a Custom Rom: Sweet_ROM_V17.1_COJ2_N910C...
Everything was running flawlessly for about 2 weeks...I installed Titanium Backup, Xposed, Xprivacy Pro, Busybox and a lot more and made a complete TWRP Backup then, it was running like a charme...The backup is fine because when i messed up my phone through trying harder xprivacy parameters and other tweaking i needed to set it back by TWRP into the old state...
Nothing happened after that, it was running 100% for over a week of heavy usage...
THE PROBLEM:
The one morning i took it from the charger with 100% Battery and went to work...
Before the error occured I did some searching on the internet, used chats. movies, nothing special this day, USB Debugging was On, i remembered something messed up my chrome browser like this ad hijackers, i set it back by erasing data,cache of chrome in the app menu, then there was nothing else strange i remembered, my AF Firewall was closed, only Whatsapp and Browser were allowed to going through...
The same day in the afternoon i tried to use my car charger to recharge my Note 4 as usual, but this time it wasnt recognizing the charger and my first thought was that the charger is faulty or the cable, so i turned off the phone by the androids power menu...I retried loading my battery In the phones off state but when i plug in the charger, the battery symbol came up for short and then it remained dead, it s the same scenario until today, so i used my powerbank to try charging, because the powerbank has an indicator to show the loading state and everytime i plugged it in, it came up for short, battery symbol shows up for a few seconds, but no percentage or animation is showing as usual and no red LED, then its switching off, the powerbank LED indicator stops the loading state after a few seconds, so the loading current stops...
At home i tried the stock charger and it remained the same, since that, i have to charge the battery outside the phone...
The strange thing is:
The Rom is still booting fine, TWRP is booting, but its not going into download mode from Androids Power Menu like before, its always just rebooting back into android if i choose download mode and i have to take the battery out and back in and hit the download mode pattern Vol- Home Power, to enter Download Mode and even the booting into Download mode from TWRP gives the same strange results:
On my Laptop i started the device manager to see the USB hardware string parameters after a windows popup was telling me something like "Device not recognized"
The USB Driver ID dont fit the old right driver ID, it seems to be empty and the port is not communicating anymore
since the charging bug occured,( Everything worked fine the day before.)
I tried my Laptop to narrow down the bug with the same driver i used for flashing phones (S6,910F,910C) over ODIN and my Lappy has USB 2.0 and USB 3.0 ports.
I always used the same USB 2.0 port for ODIN and other MTP stuff, but since the bug showed up the 910C is not recognized at the USB 2.0 Port anymore, seems to be dead in the devices manager table, only the USB 3.0 Port shows it as unknown device with a strange empty ID --> I tried the other devices like the N910F and G920F that are still recognized by ODIN on the same USB2.0 and 3.0 Ports both with the same USB hardware strings, its just the N910C that isnt recognized anymore, in no mode, no ADB, MTP, no download mode, everywhere the same, USB is bricked! Windows finds no driver and says its no info avaiable on this device so I tried to force the right driver to run with the wrong buggy driver ID but its not communicating, ODIN indicator and log remains unchanged...So it seems to be the same situation like other people getting from killing the bootloader by bad flashing, the only difference is that my phone is still booting fine into recovery and even Android but with no charging. My USB Port is totally useless now, its like if Samsung or Google OTA update has overwritten my bootloader or something hidden in the rom that woke up to kill my mods i dont know and now.
PS: Things i tried so far with no results on fixing my issue....
1. Complete fresh reinstall of Sweetrom, 2. Flashing another kernel...
3. Roll back to my TWRP Backup of perfect running ROM but with no USB support anymore:
The Phone remains in unknown state, not affecting ODIN to switch into flash mode
I am sure its the bootloader, since its battery bug is still occuring while the phone is in off state...
Unable to tell the charger the right ID without USB communication...
i was wondering if there is a solution to make a bootloader hotflash from out of Android or something like getting me back on stock first with download mode, forcing the USB ID or communication with a tool out of android, SD card boot image like on note 3 whatever, please tell me! I cant find something related to my USB and Charging ISSUE
PLEASE HELP ME, I am lost
Still the same. It's booting fine, USB2.0 no reaction on the laptop in Fastboot/Adb/Mtp ... On USB 3.0 Device remains unknown with strange Device ID String in windows 10 hardware Manager... Forced the old formerly working driver, but Odin can't find it anymore... Adb, Mtp, fastboot don't work, no communication... USB Cid is hard bricked, Charging never works in no state, just showing up for a few seconds in off state while plugging it in for short.... Bootloader must be damaged, fastboot and twrp can be started with dead USB... So is there a way to run a boot image to fix my bootloader from SD card, Aroma, or like OTA Updates are flashing? If Samsung and Google apply bootloader updates over OTA and simply restart, why we can't do that??? I need a new bootloader, is there any way without USB?
Greetings,
Thank you for using XDA Assist.
I have moved your question to your device's Q&A forum. You'll receive expert advice here. Good luck!
Fixed!
The problem is the USB Connector Port itself, figured it out after bending the inner contacts up with a flat screwdriver and cleaned them. Before that i always tried the same gently with no change, but please do it at your own risk only. After searching for many hours about possible reasons for the problem, I came to the conclusion to even compromise the Port and heavy bending it up, now it's charging! I will exchange the port soon and change the frame too to have it back like as new... OK, if anyone in the future have problems with the bootloader or USB hardbrick n910c, feel free to ask me, I upgraded my knowledge on many causes now
Thank you very much
My 2cents stick to one charger. Do not share that charger with others.
The worst culprit are the cheap china car chargers.
I went thru two USB ports on my first phone to figure this out.
Ever since I have adopted the policy of using only one cable. Never had this issue.
So yesterday I tried installing the bancontact app and it said that i needed to disable developer options so i did,
this also disabled my OEM unlock what i didn't know.
This night i went to sleep and plugged in my phone and the charger became incredibly hot so i unplugged my phone and it went empty.
This morning I try to start my phone and get a message that my custom binary is blocked by FRP lock so i start my pc and start Odin.
But the problem is my pc sees that a device is plugged in but it gives an error message that says "USB-Device is not recognized" so i tried to install the Samsung USB drivers which didn't help.
The device is listed in device manager as an "unrecognized USB Device"'
Now I'm starting to think that my port is burned out but it's strange because the phone does charge and does pop on when i plug it in the charger.
I tried different USB ports, different cables, different drivers and different PCs, nothing worked.
I tried searching for drivers to install manually but didn't find them
Can someone please help me?
Thanks in advance

Okay so now I tried one more time with a broken USB cable (it disconnects when i move a bit) and this one worked for some reason so my problem is resolved.
Hi Group... Newbie here and I am sure you will figure that out by my questions and terminology ... I am a Hardware tech specializing in Microsoldering...and Iphones at that. I just bought out another store with loads of devices I am attempting to fix and sell. I have been successful on most all of them, and now have an Att Galaxy S5 that I am getting trolled by.
It powers on (Has an unlocked padlock) while booting. but all APK's ive tried says its not rooted...
I wrote Att unlock and got approved with unlock code (Not attached to an account, not lost or stolen, clean IMEI).
I restored it using power/Home/Volume up (Padlock still unlocked)
I plugged it to computer to use ODIN to restore back to original Stock but phone will not connect to computer.
Developer mode is on and debugging checked... no drop down and not recognized by computer at all. Thinking it could be a charging / Data port (Even though it charges with computer), I swapped the logic board into another "Known Good" housing that does connect. It made 0 difference.
all other Galaxies connect just fine so Cable / USB Port / Drivers all appear okay.
Since I cannot use computer and ODIN, I wanted to try SD Card to restore original Rom... but nothing I am trying works Any ideasany

install this first
https://developer.samsung.com/galaxy/others/android-usb-driver-for-windows
when you put phone in download mode that time Odin should see the phone, if its not then also change USB cable, PC
under developer option check if its listed for charging only or mtp
also on dial pad try this
type *#0808# and enable MTP.
Gave up on this one...Can close post
Thank you for your suggestion but have tried all of that. I have 7 others that connect fine...same model with same cord and same computer. Have the Drivers, tried everything under *#0808#... However, I have tried testing D+ and D- as well and all is good. Changed u7000 as well and no change. I'm pretty certain that it has to be a hardware issue so I just gave up and put it in my parts bin as I don't know Android hardware the way I know Iphones and have too many hours in it to make it worth while
