Hi XDA community,
firstly thank you for your all your great jobs here!
I own a P605 Galaxy Note 10.1 2014. It has been "soft"-rooted (through kernel bug, without KNOXing the device) but it has probably gone out of warranty.
I experence some serious issues with any USB-related operation, let me enumerate them:
1) USB Charging: when powered off the tablet charges normally (but slowly), when powered on the tablet charges (fastly) until the screen switches off, then it stops charging.
2) USB OTG: when attatching an OTG cable, the device detect it but when attaching an USB drive nothing happens
3) USB to PC: on a Windows OS, attaching the tablet results in a "Device Descriptor" error, even with the tablet in download mode, so any firmware flashing operation is impossible. On Linux OS there's a similar error, related to device descriptors.
Obviously, when I bought it everything worked fine. Sadly, I suspect an hardware issue... I'm asking you any kind of help: tests to indentify exactly the problem and, hopefully, a solution.
P.S. I've already tried changing USB cable/USB port/PC/charger/mood/wearing/house...:crying:
Hello , i too have this problems, do you run also Lollipop 5.1.1`? Any solution found?
1) If not using the original charger/cable (or non compliant) then there's a possibility thad the data pins of the charger are not shortened. You need a charger compliant with our tablets or data-pins-shorted cable. (you can do it yourself but the cable will only be used for charging)

2) try Es file explorer (remember ntfs is not supported)
3) install kies or try

(just the usb driver)
I have exactly the same case as #1 and I fixed finally. It's because of the bad contact of the usb cable. Open the back cover (gentle and slowly prevent broke it), disconnect the usb cable from the adapter near camera, wash your hand and keep it dry, touch the golden finger one or two times with your cleaned finger, then connect it back with a little push it to the end, make sure it lock firm. ( I also use a piece 3M plastic tape to stick on the surface ). Power on and test, no problem and then close back the back cover. My machine no more that problem again. Sorry for my english not so good, and hope this can help.
With Davidmueller's Lineage and RR there is a (recurring) charging problem with usb cables. You need a cable like the one supplied, where the second GND line on the m-usb plug is not connected. The plug of the white original cable has the contact missing, i bought a recent, black Samsung cable with 5contacts,also working. None of the other cables i tried, did. The problem was there almost a year ago, got solved and re-occured during the last updates.
Results after the replace of the usb module.
As suggested by Jan&March, I tried cleaning the usb module connector on the motherboard. It solved EVERY issue for about 3 days, then they came up again. So I thought that maybe, touching and cleaning the connector, there was some bad contact on the cable. I bought a replacement part for the usb module. It has been working for about 2 weeks before showing the same issues today. I hope I'm helping someone with my experience. Any suggestions?
The pcb jack may have bad solder joints. I never had the case open, but i think the usb and display connectors belong to the components bearing most of the pressure exerted on the back cover. Except the battery and the metal shieldings on the pcb stand out more,which can only be told if you have the back cover removed.

Thanks, so what do you recommend?
That would require re-soldering. It's hard to tell, it's less likely if the connector's aren't among the most prominent parts under the back cover and won't make contact with it. I can't tell from the pics i've seen.

this just did it for me. i think the bracket that secures the ribbon cable isn't exerting enough pressure on the cable so maybe some data pins may not be in contact.

This person posted this about kindle fire not working
At first my Fire wouldn't charge unless it was placed in a particular way, then it stopped altogether. I pronounced it dead, and left it stowed away for a few months, but then decided to try and fix it. I think this guide may be useful for anyone who wants to fix a kindle with dead charging. Note that you may damage your kindle in the process so if you are still under warranty, use it.
1. Take off the back cover. You may need to use a guitar pick or something similar.
2. Take off the two battery leads. One has a locking mechanism which needs to be lifted before the ribbon cable can be taken out.
3. Take out all screws connected motherboard to rest of device. There are connections underneath the board so be careful when lifting it.
4. When I lifted it, I found the USB connector had broken off the entire board (if it was even attached in the first place) and this was obviously causing the problems, as the USB connector could now only connect to the motherboard if pressure was applied so that it was being held on somehow by it. To fix this, I could have tried to solder the tiny USB connections onto the board, but instead I used a different way which is working perfectly for many weeks now.
5. Get a rubber band and tie a not in it numerous times until the knot is about 3-4mm thick. Cut off remaining rubber band and superglue the knot onto the bottom side of the USB connector (the side that faces the display when assembled). Then insert the USB connector into it's little holder under the board, with the rubber band firm beneath it and replace the motherboard. Redo all the screws, reconnect any connectors you've disconnected (you may have had to disconnect some to remove/move the motherboard - always undo battery cables before you work on the innards of any device).
6. If you've done this correctly, the round rubber band knot should press the USB connector continuously on to the board. Test using your stock charger before you put it back together because the back cover is pretty hard to get off.
7. Replace the back cover and enjoy!
Notes: My rubber band knot was actually a little too large, which meant that to connect the USB plug I had to press the kindle together to insert the cable, but charging is reliable and working so far, so I'm happy about that.
If you found this post helpful, please click the Thanks button!
And I think he's long gone it's an old post and I need help what does he mean by connect the rubber band to the usb where do you put the rubber band where do you super glue it the motherboard kindle or the usb and what does he mean by tie it how do you tie a rubber band
(Not a native english speaker, sorry for any bad writing) Good Afternoon, first post made in this forum and I'm very desperate to find out why my tablet is not charging, I have tryed with 2 different charges and 3 usb cables but nothing, but when i connect a OTG cable with or without a USB pendrive in it, this will be recognized so i'm not not sure what the problem may be.
It is the chargers?
The Micro USB cables?
Or the Power Source?
Plz help me. Thank you.
Edit: Forgot to add, it will occasionally after several Hours to start charging back, but if i move it just a little bit it will stop charging.

This is your problem: loose USB charging port. Search Ebay for this part, may be cheaper if from China
Be aware that a defective USB port can read data but not charging or vice versa.
http://www.ebay.com/itm/ORIG-New-US...108?pt=LH_DefaultDomain_0&hash=item5d5a6ac87c
Replace this one is easy, just need taking the back cover off, remove two screws from this USB flex FPCB. Make sure search YouTube how to open the rear cover. Open the wrong way, you'll permanent damage it. Don't ever use metal prying tool to open the case.
This one is just an example:

I've seen reports of this before, and it always seems to have been a hardware issue. You could try a factory reset, but it's unlikely to help.
first step try as many different leads as you can as it could be faulty leads, it's the most common problem but as you say it's happening with multiple things it probably isn't this.
had similar problems on other phones alcohol and a thin pick has tended to fix it when I've needed to do it.
one way I've found that works to clean it out assuming the USB lead is going in fully, (if not use a thin pick as it could be a bit fluff in the bottom of the socket stopping it engaging fully) is to turn off the phone get a disconnected USB lead, (very important it isn't plugged into any source of power during) dip the end that plugs into the phone in alcohol (proper cleaning alcohol not just drink as it evaporates quick) put the plug in and out a couple of times, let it dry out then repeat a couple of times, if it's just dirty contacts this will clean it, just make sure when connecting the USB lead is just damp and not dripping to avoid any flooding of the socket.
outside ofm that I would assume it's a hardware fault.

Thanks for your help...
Fixed it by using electronic cleaner spray its made my day ,moisture alert appears and after four hours gone after that its works!!:laugh:, i dont know if its bad but it fixed this problem
was possibly just a short in the socket due to dampness for a while, but the port should be waterproof like the rest of the phone really so nothing should have really got in the phone.
but if it's working it likely was just dirty contacts.

Thank you for providing detailed instructions on port contact maintenance. I started having issues right after updating to A11 so assumed ultra fast charging on my note 10+ broke due to that update. However, just to be sure i ordered new oem block and cable and the ultra fast charging began to rapidly cycle from on to off, so i did more research and came across your reply. I dipped both ends of the old usbc cable into a half oz of reagent grade alcohol 99%+ shook them off so there wasnt a full drop of alcohol in them and slid the cable in and out a few times. Then let it dry for a min and plugged it back in to the new block using new cable. It seems to be stable now, however as i write this reply, it cycled twice between on and off, so I'll keep trying to clean the port and report back if successful.
Confirming that cleaning the contacts on the cable and phone using reagent grade alcohol and a thin pick worked to resolve the issue. Examination of the port and cable with the naked eye did not reveal fouling. Keep that in mind when deciding on trying the cleaning.
Now the pixel 2 xl support ended i am trying to root and install custom rom. But my device is not debugging...
When connected to pc only charging.. no usb options.
I can connect the usb drive and other peripherals
Usb debugging enabled in developer option.
Tried different cables.. different port.. different pc..
Is it usb c port problem or some software problem?
Any help advice!!!
Thanks in advance
I've got the same problem. Many have said they had success with different USB cables, but I've tried dozens without any luck.
I'm thinking hardware at this point, since I finally got the last OTA update and it made no difference.
I'll order the internal USB replacement part off ebay and see if it makes a difference.
I just replaced the internal USB assembly and nothing has changed. The old connector was definitely worn though.
I'll go back to trying more cables and ports. I ordered a cable that another poster claimed worked for them, but I had no luck with it.
For anyone wanting to replace their USB ass'y, here's what I learned from doing it. The service manual on ifixit is a good guide but leaves out a couple of important steps.
Heat is your friend. I used a clothes iron adjusted to 160F. The phone dissipates heat quickly so you may need to heat it several times. Place a towel over the screen and set the iron on it. I used guitar picks to pry up the screen and keep it separated while I heated the other sides.
The screen cable connection covers are hard to remove and you'll probably need a to use a metal spudger.
Heat the back of the phone to help remove the loudspeaker ass'y without damaging it, and again to remove the old cable ass'y.
The replacement ass'y I got had adhesive applied for the center of the cable, but not the adhesive foam pad under the antenna connector, so heat and scrape between the pad and phone body to remove it intact for reuse.
My old antenna connector partially came off in the white antenna connector and it was very hard to see what was wrong even under strong magnification.
You'll need a new screen adhesive sheet to reattach the screen securely.
Both parts came from a seller on ebay. Dougsgadgets was the only one that had both parts in stock. I think I paid $11 and they shipped quickly.
Good luck!
Hi,
I recently purchased a refurbished Nexus 7 (2013). It’s running Android version 6.0.1, the Developer options is activated, and USB Debugging is turned on.
It has worked perfectly since it was purchased last December until a few days ago. Now when I connect it to the computer the battery icon shows it is charging, but the usual USB options on the notification bar don’t appear. It’s not a defective USB cable as the same cable on the phone, a Nexus 5, shows the USB options for file transfer.
To rule out the possibility of app conflicts I did a factory reset using the power and volume buttons. Still no joy. I came here to ask if there is anything else I can do ... or is it a matter of replacing the USB port daughterboard?
Thanks ...
I have a Nexus 7 Deb 2013 with a similar problem. I have traced the problem down to the internal connector on the motherboard where the ribbon cable coming from the daughter board connects to the motherboard. Only if I apply pressure on this connector, does my PC recognize the Nexus 7. The back cover is designed to apply some pressure on this connector, so I may try adding some cardboard between the back cover and the connector to see if the increased pressure on the connector solves my problem. You quite possibly have the same problem.
Please let me know how the cardboard fix works. Size, thickness, and placement. Cardboard I've got. Fresh out of Nexus 7 specific daughterboards. Will heat be a factor?
The workarounds so far are to transfer data to and from the server via WiFi and if/when the charger side of the USB port dies I was going to pick up a wireless charging pad. But cardboard sounds way cooler.
The point is this is a great tablet that I'd like to use for a Very Long Time.

I’m not that familiar with the flo version of N7, which are you having this problem with, deb or flo? On my Deb, there’s a wide ribbon cable for charging, SIM card and screen touch support and USB port data transfers. The flo version of this cable is narrower. If you remove the back cover from your tablet, there should be an insert on the inside of the cover which presses down on the motherboard’s ribbon cable connector. With the cover off and your computer connected to the USB port, press against this connector and see if pressing against the connector temporarily restores USB connectivity. If so, adding some cardboard between this connector and the back cover will increase the pressure applied by the back cover. Some experimentation will be required.
My problem started when I opened up my N7 to replace the battery. This required temporarily disconnecting the ribbon cable from the motherboard and when I got everything back together I had no touch input from the screen. I eventually discovered that pressure on the MB ribbon cable connector solved this problem and that this same cable carries the USB data too.
Good luck repairing your N7.

I've got the WiFi (flo) Nexus 7. I've also got the burglary tools to break and enter The Phone. Did you ever get touch input back?
It’s pretty funny, I had given up and I was going to put the tablet in the e-recycling bin in town here when I happened to accidentally press on just the right spot on the back of my N7 and I got a touch response. So I took out the ribbon cable and cleaned the conductors and the MB connector which fixed the touch issue, but I still have your problem with USB connectivity which gets temporarily resolved by again applying pressure to the MB ribbon connector. As I said previously, some thin layers of cardboard placed between the connector and the back cover may just solve both our problems.

I think I might try using playing cards (one at a time) until I get the desired (functional) thickness.
Good luck and good night.
