My USB port died a few months ago - no data, no charge. I've been getting by with an extra battery and the external battery charger, but I'd really like to be able to transfer file between my computer and my phone faster than Kies does.
I watched a few videos on how to do the replacement and ordered the part. When I got it, though, I notice on the replacement board it says "rev 0.8" while mine says"rev 0.7." On visual inspection they look nearly identical, some different in the shape of the USB port. But I don't want to take a chance on frying anything.
Anyone have any idea if I can use this replacement or not.
Thanks in advance.

Hey all,
I have a Galaxy Nexus which recently started to act up on his USB port saying it's constantly connecting /disconnecting to the charger with no cable present.
Device: Samsung Galaxy Nexus
Edition: Maguro GSM
OS: CM10.2 nightly + CM11 Alfa
Chargers: OEM, generic, battery & laptop
Cables: OEM & generic
Reproduceable: sometimes
This week I noticed my phone did not react immediately when I plugged it into the charger. Mostly after some fiddling (bending the cable away from the screen) it would start charging. After pulling the cable or removing the charger from the wall, it would generally take 5 to 10 sec for the phone to realize I pulled it- this used to be instantly.
Strangely, when the phone said it cannot charge it can be connected to a computer as Media Device without any problem. Charging only happens after the fiddling again.
Looking into BBS, it cannot give any stats because it says the device is connected constantly to a charger. Android original battery monitor stats are also a mess but it does not say I am connected always.
Every now and again the phone also starts making notifications as if he was constantly connecting and disconnecting - leading to frustrated looks of the people on my train...
Cleaned out the port - no success
Hit it on the train table - no success
Reset, battery pull, flash, different OS - no success
After this all I think it will be a hardware issue. Nothing seems bent and no pins seem to be sticking out. Removing the back and checking the mother board showed everything still intact and all connectors still in place.
I'm guessing now the micro USB connector of the phone has somewhere some corrosion or a pin out of place but not visible to the untrained eye.
Can someone shed some light please?
2 screenshots to show you what I mean.
No, I am not up for 9 hours and lost only 10%... Battery life has become horrible since this issue. It just thinks it's constantly hooked up to a power source and I think it's no longer power efficient because of this. I already disabled charge connection sound because it was driving me crazy ...
Please help if you know even half a solution. I can also post a photo of the connector but the problem is that there's not much to see there...
I think you have problem with charging circuit >>if you have solid knowledge in electronics you can simply replace it
replacing this port in attached pic will solve your problem .... otherwise you can fix your own port because I think one of your USB port pin are touching the ground chase of your motherbord
Thanks for the reply. Somewhat saw it coming I would have to replace something...
I already looked on some sites like ifixit to see what I could do but I thought to have seen that the Motherboard was in one big piece.
Could you please give me the website where you found this or the name /article code of this component?
Thank you

try to follow the steps on the link it is very helpful http://www.ifixit.com/Guide/Repairing+Samsung+Galaxy+Nexus+(Verizon+LTE)+Micro+USB+Charge+Port+%26+Main+Mic/9641
and you have nothing to do with the motherboard just take the old charging port and install the new one
Ordered a new part. Hopefully it'll work...
Hello community,
trying for half an hour to connect my note 3 to the pc using the OEM usb cable, I kept getting error 43 "Unknown Device" stuff but the phone was being charged. After that, I plugged it in my usb 3.0 external drive cable and got recognised instantly. What do you think is the problem here? I did happen to land the phone-edge of it in a yogurt bowl last week but, after cleaning it, it has been working normally this much time!
(Hope) someone else had a similar experience and worked it out...
Thanks,
jim
Original cable that came with my Note 3 has broken wire inside from new, I need to move it around few times just to get it connect inside and charge phone, Note 3 itself works fine with usb2 cables, or usb3 cable from my back up HDD, so I strongly suspect one of the wires inside your cable broke or has poor connection as well, but here it's data line, not power like in mine. Solution is very simple, use another usb3 cable, that should give you fast charge, or even usb 2, but here probably charge will be slower. You can find inexpensive cables online, also I don't think cables have full 1 yr warranty, like phones do but you may as well try warranty claim. BTW there is nothing special about Samsung charging cable as far as I know and at least in my case any USB3 cable will charge my phone at full speed, just like original cable as long as charger is original.

yes, Kies 3 has been installed since the beginning with the drivers. And as long as the phone is recognised through another cable, the drivers are definitly installed! Thanks again!

As long as I have the backup cable, I just leave the OEM in the wall charger and everything is fine. There is the fact that my Knox is 0x1, but I can just try the warranty with the cable and the receipt :angel:
Thanks again!
To make it as short as possible, My original note 3's logic board died, so I purchased another Verizon note 3 from eBay that claimed to work, but had a bad charging port. Since my original N3s charging port worked perfectly fine, I figured I'd just swap the logic board over.
Well, the blasted thing still won't charge. It won't even recognize being plugged into USB. I've tried several different cords... Ranging from the stock USB 3.0 one, to the Galaxy Tab 3 cord... To cheap Gas station car plugs... nothing seems to work at all. I've tried wiggling the cable thinking maybe it may be loose, but that didn't work. I had NO issues with the charging / USB port when it had the original Logic board in it.
So, What are the chances the logic board has messed up USB / Charging circuit? Is it possible I didn't get something connected right? I figured if I did, Something wouldn't work... But everything does, Except usb. (Speakers work, Mic works for calls, home / soft button and lights work)
EDIT: I took it back apart and checked all my connections and refreshed them, Didn't change anything :/
I even tried this: http://www.youtube.com/watch?v=mwTrlMomZ6o with no luck.
So it seems like the Logic board has bad USB. What are the chances of that happening?
Anyone at all? Gonna have to resort to a wall battery charger to use this phone.
Mine will not charge either and just started doing this about a week ago. Luckily I had bought 2 extra batteries that came with a wall charger. By the time one battery is dead the other is charged. My N3 only last about 6hrs or so.
Hello, I just recently replaced the screen, back glass and battery in my friend's Nexus 4. Last night the charging port caught fire and fused the cable to the port. He had a look at the battery and that looks fine so I don't think that's the cause. Anyone have any ideas on what could have possibly caused it? Also would replacing the cable and usb fix it? The rest of the phone looks alright in the photos, or would it be likely to do it again? What would people recommend? Thank you.
I wouldn't safely say the battery is "fine" after such an accident. I'd replace it again, together with the port, and use a proper cable from now on... There are too many variables to take into account but I don't think that an original battery, for how exhausted and f*cked up it could be, would cause this havoc.
Ok, thanks for your help.
Replace your charging cable, do not use cheap chinese brands. If you charging directly from electric socket instead of computer usb etc, i would check if there is grounding available at power sources in your house.
Hi XDA,
After being a long time reader, it's time to ask you guys for some advice. My S7E still works great after 1.5 year of quite intensive usage. So far so good.
However, over the past couple of days, I've started to notice that my phone wasn't charged at all after putting it on the charger for 1-2 hours. The first 2 times I just thought that the cable just wasn't in properly, because after I reconnected the cable, it did charge. A few days later it just stopped charging at all. After testing it on a wireless charger of a coworker quickly, I knew the battery itself was fine. I tried a couple of cables, both new and old, but it wouldn't charge. Because I also used new cables, the cable wasn't the problem either.
So then, as a last resort, I tried to push the actual connection part (having the pins on it) within the port on the phone a bit inward. This so the pins in the port would better connect to the pins. And Boom! It started charging. So then I knew where my problem was. But now every time when it stops charging again, I have to do this over and over. This puts stress on the connector, and after repeating this process enough times, it will eventually break.
So here's my problem.. Because of how contracts are setup here, I can't open my phone up myself to simply replace the USB port (namely materials, but also certain skills). Also the repair service that is suppose to do the replacement, basically just sucks. They gave me a phone with a bend LCD back last time. I've fixed it myself afterwards back then. I don't want to send it there, except for screen repair.
So I'm looking for a way to either fix this connector permanently without opening my phone, or a specific type of cable focussed on bad connectors, or whatever might help me in this sitation.
Thanks for all your advices!
Wireless charging is ok. Its not as fast as usb but it gets the job done

Thanks, but that's only part of the problem. Let's say I need to connect my phone somewhere on the fly for whatever reason. Or are maybe on an airplane or something like that. I'll always need to bring toothpicks to fix the port, up until it breaks.
Mine s7 edge just stopped fast charging one day and PC doesn't recognize the phone anymore. It's still charging slow though.

just use airdroid. can trasnfer files wirelessly.
Well, let me clarify a bit... I know there are workarounds for the issue I'm describing. I could setup SMB and transfer files through that. The heck - I could write my own app, using my own "protocol". Charging can be fixed through wireless charging, thetering can be fixed using the hotspot, adb can also be done wirelessly, and terminal access I could get through an app. I could continue for a while here.
I actually want to fix this specific problem under the given circumstances. Not just dozens of workarounds for specific tasks. Let's say I **** up flashing, and need Odin to restore my device.
there isn't a way to "fix" this without removing a LOT of small, fiddly bits inside the phone. You certainly could get a micro-usb extension cable an leave it plugged into the phone all the time, or MAYBE use a Mophie Juice pack (a battery pack in a case that has a micro usb that plugs into phone and a new port that is on the edge of the case...
Other than that...SOL...
No sorry you can't, its nearly impossible to replace usb port without opening front panel and screen, and there is not a single percent chance to prevent screen from damage when opening front panel and glass, its simply doesn't designed to be opened. Go to samsung care center and give them the fee to replace usb port, if your screen got damaged during repair, they will replace it themselves.

Kinda was afraid of that, thanks for confirming. I like the idea of the case, hadn't thought of that. But the idea of the extension cable got me thinking. I think I'm gonna order some of those magnetic USB cables. They have a small adapter that barely sticks out. Then I simply need a few cables, for work, home and on the road. Because the adapter has no reason on move, it should be alright.
Thanks for your suggestions everyone!
