N9208 Main Board Replacement. - Galaxy Note5 Q&A, Help & Troubleshooting

Hi.
Just recently my N9208 device can't use fast charging. No OTG and cannot be detected by any computer as well. It just says cable charging. I brought it to a cellphone repair shop to replace the charging board. To my surprise it does not fix the issue.
The technician says the main board must be replaced. However the price is too expensive and not practical.
Anyone here encountered the same issue?
I am currently using a customized s8 rom when I encountered this issue.
I can't flash a stock firmware via odin to check if it will solve my problem since pc does not detect my device.

I just wanted to send my phone to support with same problem - only loading battery, no usb debugging or mass storage connection.
But i found out, that my connector at phone was just dirty (much dust) so i cleaned it with some piece of plastic (carefully).
The dust was at the bottom, not at the pins itself, it prevented the cable from slipping in enough to connect to the shorter data pins. (check with a flashlight).
Maybe thats also your problem...
Had the same problem in mine. Used those air sprays that clean keyboards AND!!! a tooth stick After that - everything was working again.
And from now on, I ALWAYS close the cap of the micro USB port
There is also could be a problem with USB controller. Make sure you connect device to USB2, not to USB3.

[Q] Only charging when off - no USB Response

Hi All,
Got a bit of a strange one. I have a stock HTC One on Three UK, nothing customised and certainly not rooted.
I am only able to charge the phone when it is powered off (as you can imagine this is a major inconvenience), a charger is not recognised when I plug it in while it's turned on - not only that but the device is not recognised via USB when I connect it to a Mac or PC.
Im just wondering if anyone else has experienced such a problem or whether it's time to make use of the repair warranty?
Regards
Sam

Note 5 USB Port Not Working Except for Slow Charging

I have researched the issue of my Note 5just being able to slow charge via USB, and not be able to do anything else. I have tried all the proposed solutions I found, but can not fix the issue. The things that I have noticed to not work are:
Fast Charge: Cable and USB charging is detected, but cannot fast charge. I have tried the same charger and cable on other S7 edge, and it able to Fast charge. Fast charging is enabled in the battery menu
Connect to PC: Whenever connected to any PC, the PC shows “USB Device Not Recognized." I have the latest version of Smart Switch and the latest drivers. I have tried multiple computers and windows 7, 8 and 10. I have also tried to connect to the PC when the phone is in Download and Recovery mode and get the same error.
Connect to any OTG peripheral: Nothing is detected by the Note 5. Same cable working on other device.
Connect to Gear VR: When connecting to Gear VR, it gives the chime, the black screen with the little x in the corner appears for a second and then it goes back to the home screen.
What I have tried to do to fix:
Different cables/chargers/USB ports
Checked if any of the 5 pins are broken in the cable
I have lifted the tongue of the charging port in the phone via tooth pick
Done a factory reset
Any insight on this issue would be appreciated.
Thanks

Have you tried different 2A charging bricks? A regular 1A charger would still take a long time to fully chargeNote5.
You could also be looking a bad USB-port or a faulty battery, both of which would be covered under warranty provided no large physical damage is evident on your device.
Thanks for the reply. I have tried the original Samsung charger, 2A, 1A, and 0.5A charging bricks, but the phone shows either Cable or USB charging.
About the faulty battery, will that cause the PC and other peripherals to not detect the phone?

Same happened to me two days ago. I restored an old backup, done a factory reset and restored my actual rom again and problem solved. Idk what the problem was related to. Try wiping cache again, maybe it helps.

I have done a wipe from TWRP, but the issue was not fixed. I can not change ROMs etc as I can not connect the Note 5 to the PC via USB cable, even in TWRP.
Was your phone just not Fast Charging, or it wasn't being recognized by the PC, etc.
Thanks
Actually y have the same problem, unfortunately I don't have root access.
Try the app called USB host check, maybe they can help you.
Is not possible to me because the PC don't detect the phone connection and obviously I can't make the root.

I have the same issue tried the same fixes. No luck. Have you found a solution please?
I ultimately had to change the motherboard. Changing the charging port did nothing.
However, I suspect it was a corrupted firmware. If you can somehow flash a latest stock firmware and check, that would be great.
In trying to fix the firmware I had corrupted Stock ROM. Since I could only use WiFi to transfer files via WiFi FTP type apps, and I didn't have a working ROM backup on my phone, after the Stock ROM was corrupted, I could not upload any new files to flash with TWRP so I had to change the motherboard.

If you see the "USB Device Not Recognized" message when you connect to the PC, then I think the charging port is fine. It is some issue with the firmware as phone is not able to provide the correct PID and VID to the peripheral devices to identify itself. The charging port and its circuit doesn't hold that info. If possible, try to flash a stock firmware from TWRP as ODIN will not work (I am not aware of the exact procedure). Just MAKE SURE you have make a backup of your current setup and leave it on the phone as if you have an unsuccessful flash, you will not be able to use ODIN or ADB as your cable will not work.

I've messed up, I've already clear the cache, Dalvik , Data and System without having backup Rom/firmware in my internal memory. I've try using OTG. Still no hope. Twrp won't regconized it. :crying:
If there no hope to solve this... I think ,I will sell my note5 for replacement parts , sadly.

I got into the same problem. I then ordered a replacement motherboard from China and installed it. After that it is working flawlessly.
I'm in same predicament pc won't recognize phone and charging is extremely slow. Attempting to restore old twrp backup or flash older firmware. Crossing fingers

Are you still interested in selling the phone?
Same problem but with 2 phones
My note 5 and my friends S6 edge were totally fine, but on our farm (which now i found that has a low voltage eccentricity at around 190 V), we put them on my charger (the original charger that came with the note 5) and both of our phones now have the same problem, they charge very slowly ( up to 6 hrs for a full charge) and are not detected by any pc using 3 cables that work with other phones normally, the charger itself is okay, and works well with other devices (at home of course, and fast charge works with other devices).
I have tried everything, restart, safe mode, delete cache, charge while its off.. with a number of chargers and cables, it does not make any difference.
If any one knows how to fix this, your help is appreciated.
Mine is a little different, My Note5 is not charging at all via USB but works fine with wireless charging. In short, even if i plugged it via PC or via charger, it does not charge anymore.
But I noticed something, when I am in TWRP recovery, my USB OTG drive is readable and when i am in download mode, Odin reconizes the Note5's COM port. I did a reflash of the stock ROM hoping this will do the trick. but it failed. still does not charge at all via USB.
Can anyone help me with this? Thanks in advance. all answers appreciated.
this seems like you have faulty usb port .

PC does not recognise phone [device descriptor request failed]

So the story is that i got a samsung galaxy note 5 (n920i) with a broken screen from my sister and it worked fine before. A year later i fixed the phone and wiped the files, cache and stuff i noticed that it did not charge with my aftermarket charging cable (battery was at 0%). I thought the cable was screwed so i used an official samsung one and it started charging. once it started up i did all the startup installation process and such but then i noticed that it would not use fast charge (i have an official samsung fast charge socket) even with the fast charge setting on. so i thought to plug it into my pc but it does not recognise it at all. (device descriptor request failed every time) I used many different ports on my pc and laptop, used many aftermarket and official charging cables, i even used it on devices like the gear vr and a docking station and they dont recognise it either.
I found a post saying to push up the tongue in the charging port which did not fix it, i tried all such drivers and fixes thinking its my pc and/or laptop but no luck, like i said i even used devices like docking station and gear vr and both dont recognise it either. So i just thought it may be the charging port its self and purchased a new one to install(i also got a new battery just incase) . After replacing both the charging dock and the battery successfully it still does not work on my pc nor does it charge properly. it is running on the newest update out right now.
edit: I also lost the little white signal cable for the antenna while replacing charge port but i have purchased a new one and its on the way. (if that causes an issue)
I have tried using samsung kies and smart switch with drivers and it does not recognise it either
I dont know what else to do can someone help me figure it out whats wrong.
Thanks
I have the same problem.
Is there any way to root note 5 n920v without pc?
My phone have a problem that does not connect to pc with usb cable, my last hope is to try to install a new firmware.
By research, i think its a software problem.

[Q] Replacing T810 motherboard with T813 motherboard.

My Tab S2 - T810, has started to show slow charging problem. I have tried changing 5 different brand charger, 8 different charging cables, but no luck.
Also the PC-USB connection problem is there, meaning when I connect the tablet with my PC and others PCs or Laptop via USB, it doesn't show up on the PC in any way.
It has no warranty so cannot change it from Samsung.
Even after reading so many threads in many websites, I couldn't come to a conclusion.
One thing is for sure that, at least, I have to open up the tablet and unplug and replug the battery for slow charging troubleshooting.
As I will have to open up the tablet, I was thinking if it is possible to replace the T810 motherboard with the T813 motherboard, and are there any benefits to it?
Also anyone can suggest any other troubleshooting tips for this.
