Felt a funny smell, like copper melting. Some smoke was coming out of the charge port so I withdrew the cable and the plastic around the connector had partly melted and there were burn marks on the metal parts. Hopefully it is only the cable, my guess is that years of packing and unpacking finally broke the cable and caused a short. With luck I might just need to replace the cable and the charge port will still be ok.

Hey guys
Like many others my usb gone bust and my advent tn7 just became useless. Ive went to curries and explained about how this is a common issue but they dismissed it saying a broken charger port is my fault. I have searched several forms but still havent found any way of fixing it. Does anyone know how to get my tab to charge? Ive tried opening the tab but one side of it doesnt seem to come off. What are my options if any? Any help will be greatly appreciated. Thanks.

The best option would be to take it to a repair shop... it might cost you $50, but hopefully they can replace it with the right USB port (the one Nvidia used is slightly different from most micro-USB ports you see on devices, so it's not a very snug fit, hence the problem.)
I have the evga tn7 that i bought from newegg. Would they still honor my warrenty on the broken charging port even though I have my bootloader unlocked?
jon7701, I was thinking the same thing. I bought mine a couple of months ago and the charging port is being a little finicky.

Mine has to be plugged in a certain way or it refuses to charge outright. Even when I have it in the proper way it might not charge at all but reports its charging. The strange thing is that it can still detect what type of charging method (usb or AC) im using even though it wont charge.
I was able to fix my EVGA Tegra Note 7 usb connector using a re-flow soldering station (the type that uses hot air to melt solder), and it only took about 30 minutes. If you know an electrical engineer or serious electrical design enthusiast, they may have one. The problem is caused from the solder joints on the usb connector breaking. All I had to do is re-melt the solder and the problem was fixed. You cannot use a normal soldering iron because there are other components in the way. This happens on the Tegra Note because Nvidia specified a Micro-ab type connector instead of the Micro-b connector that most phones have. This allows accidental upside down insertion to damage the connector.
All you have to do is snap the plastic case apart, carefully remove the small circuit board that has the usb connector. The solder joint appears solid, but I was able to see the crack with a microscope and a trained eye. Use hot air to melt the solder, and resemble. Now I am just careful to plug the cable in right side up. If it breaks again, I am replacing it with a Micro-b connector.
I like having a re-flow soldering station. Every hacker should have one for replacing surface mount components and more extreme hacks (like upgrading internal flash, etc.).
sorry for necroing this post but i'm having the same issue. i've thought the same as you of replacing the port with a micro b. i have only one question: is there any problem with replacing it with a micro b? or no problem at all

Thanks a lot for your correct advise.
I had a long battle getting my Xolo Tegra Note fixed in Pune.
Xolo service center people told me that because I have down graded my tablet to KitKat, now motherboard is gone. After that I went to local mobile repair shop, he told me it's very difficult fix this as the joint are very small and soldering can damage other things as well.
After visiting a few repair shop in Pimpri market, I found a guy who did it. I found the same issue of minor crack which he found using multiple magnifying glasses.
It's better to visit a good repair shop not a small one as the issue won't be visible without magnifying glasses.
Let me know if anyone wants to get it fixed in India, Pune. I will share the mobile shop address.
So I have been using the phone for 2 months now and charging everyday with the original cable. The metal surrounding the charging port has few scratches with the paint chipped away. I always made sure to insert the type c head slowly and carefully.
I just wished zte would have put a plastic gasket fitting into the charging port like the nexus 6p. https://cdn2.pcadvisor.co.uk/cmsdata/reviews/3626455/google_nexus_6p-1236.jpg
I was wondering how everyone charging port looks like after few months of usage.
I will update with pics of my charging port when I get a camera.
edit http://i.imgur.com/0avTbrz.jpg the lower right side has scratches
My port looks like day one to be honest.
Why would it scratch if you insert the cable "slowly and carefully"?
I got scratches trying to put it in a VR headset. Other than than no scratches anywhere else but charging port.
How much force would I need to exert for the connector to break? I'm asking this because I've heard that the connector isn't replaceable without replacing the entire motherboard, and I'm a bit paranoid about it breaking:silly:. Thanks in advance!

Owned g3, g4 and now v20. Totally normal to ask about this. Even if you protect your phones with cases and tempered glasses, two primary weak spots remain: motherboard battery contacts wearing out and breaking off (happened to me on my G4) and USB-C troubles. As both the battery connector and the USB-C port are soldered onto the motherboard, even if your phone is under warranty, the only fix is installing a new motherboard, losing the data (back up your data often!) As I was explained in the service center, taking the parts off the motherboard and soldering the new ones back on (that's only if you have a donor motherboard or parts to begin with) results in heating the surrounding circuitry area to the temps of up to 400c, risking damaging the metal tracks (or ripping the seating metal pucks for the parts off the board altogether on removal).
Since the g4 mishap, my solution for effectively protecting the USB port from wear, pulling and yanking damage is the permanent (but easily removable) magnetic USB-C insert that lives in your phone all the time and has magnetic studs on the outside plane that the charging cord snaps to. There are several manufacturers of those on Amazon, none are perfect but any of them is better than using your port "raw" daily. WZKEN makes tangle-free USB-C cords with strong contact between the insert and the cord. The cords (at least in my case) support Qualcomm quick charge 2. When connected through a WZKEN cord, my Anker QC2 charger plug changes light from blue to green to indicate QC and my phone notifies me QC is on, so the QC handshake works as expected.
One thing though if you go the magnetic rout - order MORE inserts than cords, if your USB-C port is loose, the inserts might fall out every once in a while, you'll lose them. Also I haven't seen any magnetic cords with light indicators that change color when QC kicks in, all the light shows is that there's electricity in the port on the wall charger that your cord is connected to. Also, WZKEN cord heads snap to the inserts the right side up only, not on either side.
Whatever the quirks, beats the every day pounding that USB-C ports take by far, especially knowing v20 doesn't charge wirelessly! Inserts are small enough to fit into all port cutouts on all cases I have, so no problem there, either.
The solution is so simple that I charge most of the micro-USB and USB-C devices in my house this way.

Hi there.
A few months ago I dropped my refurbed, less than 2 month old, N4 on a chair leg and the housing around the charger port broke. I was told the motherboard was screwed, hence why the charge wasn't lasting. I decided the phone was too good to get rid of so I kept with it. The other day the official charger lead cable charger USB plug snapped. I put it down to being squashed by a chair. However, another cable did the exact same thing (and wasn't squashed by a chair). Could it be as a result of going into this bent housing? What is the solution.
Thanks
A bit difficult to ascertain what's actually going on without something to look at.. Would you mind posting a few pics of the housing around the charging port and the snapped cables.
On a lighter note, Looks like your N4 doesn't quite like being around furniture (chairs, specifically )
First of all, I have moved on long ago, my production phone is a Nexus 6. So with the N4 gathering dust in a drawer, I decide why not take a chance with it. The N4 was fully functional, but like many others had a partially splintered glass back. Years ago I had bought a replacement back that I never installed. So I thought, why not replace the back and with the back off replace the battery as well.
I made one mistake in the process. I didn't realize the battery had a wire taped to its side that that ended in a gold plug that attaches to a socket on the motherboard. When I removed the battery which was glued down I pulled the wire out of the plug. I then soldered the wire back onto the plug, and at least my voltmeter showed continuity.
One I reassembled battery is ok, wifi works, but no cell service. The phone sees the difference between the SIM being in or out, but no service. The SIM gave service before the surgery, and also does in another phone.
I've taken it apart and put it together a few times, making sure the plug is seated in the socket and the there is continuity between the bit of exposed wire and the plug..
One other thing caught my eye. The old battery has a silver foil backing apparently glued to it. The replacement battery does not. Could there be a shielding issue?
At any rate I thought I would ask for any suggestions. The loss of cell connection is not a tragedy. My plan is to use it to play with different roms while sticking with stock on the N6. for my real use.

This wire is coaxial type and because of the size it's almost impossible to repair it correctly.
I would suggest to buy a new one, form here:

or look on ebay/aliexpress/google/etc. for part number: EAD62290101
