Ok, I've searched for a couple of hours with no luck, so please don't kill me if the answer is already out there.
I plugged my phone into the pc and transferred a couple of files, nothing malicious. Now, when I plugged it back into the A/C adapter that came with the phone, it won't charge. I tried it again on the pc and it charges that way. I tried my girls Epic charger (with the A/C adapter that it came with) and it started charging...for about a minute. Now that one doesn't work with the adapter either, only the pc. Does anyone know what the deal is? I need my phone for work, as I am in the car all day, but I am afraid to use the car charger because I fear that will stop working as well.
Please help if u can. If u have any questions, please ask. Thank you very very much!

Anyone? Im kind of desperate here

Kind of an odd problem, and I don't have specific knowledge of it. But just some random ideas ("couldn't hurt" type stuff): have you tried powering the phone off, than on again? Or try taking out the battery and putting it back, making sure its firmly seated, and all contacts are touching?
Thanks for replying. Thankfully, my phone accepted a charge from the car charger. I did try a battery pull and reboot.
I found out the hard way that whatever happened also screwed up some settings...for example, the phone did not vibrate when the alarm went off this morning. I went jn and manually changed stuff back to my settings.
So basically, I can charge the phone with its original usb on a computer, but it won't work when plugged into the AC adapter. I can use the usb/ac adapter from the Epic (yesterday I thought I couldn't...that was my mistake). Essentially it seems like the usb or phone itself damaged the adapter, so it will no longer work. Problem is, I don't know if it will happen again. I'm toying with just contacting tmo and getting the phone replaced, but I don't know if they will send a new one (I got my phone in october, a couple of weeks after released)

Have you tried using your charger to charge a different phone? It might be possible that your AC charger is busted?

That's what I'm thinking. Its pretty unusual for a phone to accept a USB charge and not an AC one (the reverse seems the more typical problem). And especially if a charger for a different phone works.
I'd ask T-Mobile for a new charger, and go from there.
Thanks again for the replies, I really appreciate it. Yeah, I tried using the ac adapter with the Epic, using both usb cords, all with no luck. I just don't know how this happened. Plugged into the computer, then into the ac charger (like a hundred times before) and it kills the ac charger? Weird, and I'm worried about it happening with a new charger...I'm still under warranty, does tmo send new or refurb phones as replacements, I wonder...lol. thanks again!

I've had by CDMA GN running 4.0.2 rooted stock for several months. Previously I've had adb running over both windows xp and ubuntu without any problems. Suddenly out of the blue, now neither computer recognizes the phone. I tried switching between mtp, ant ptp, restarting device, turning usb debugging on/off, trying a different microUSB cable -- nothing.
Any suggestions?
Hmm.. I suspect a broken USB connector here. I think this is one of many consequences of this issue: http://forum.xda-developers.com/showthread.php?t=1427539
Possibly, however to the best of my knowledge the device charges correctly and without issue. Frustrating.
I'm going to try to reset the device and see if that make any difference. Looking at the usb port nothing looks totally out of wack.
As I recall, my problems with the connector started with not being able to connect.
Does it say Charging (AC) under Settings->Battery when you connect it to your computer? This could indicate a connector problem.

I want to thank you first of all. After perusing through some of the links you directing toward, I actually took a small knife (one with a point on it), and actually slightly bent the usb connector on the device, repositioning the plugin toward the center of the port rather than toward the back. After doing this a couple of times, the device was recognized. Based on this, I'm inclined to believe the USB connector is in the process of failing.
(***Rant -- pisses me off, I've only had the device for a little less than two months!!).
Was in difficult to replace the USB socket?
Not that hard after looking at some dissasembly videos of the Nexus on youtube. But if you are unsure, I would recomend returning it as this is clearly a warranty issue.
It would be hard to prove its a warranty issue at the moment being that its working for the time being.
I'm always up for the challenge anyway. Part is only about $10 so nothing to extravagant. Do you have a link to those videos? I think I'm going to go ahead and just order the part as a prophylactic measure to scare away ghosts. If I never need it, no big deal. I gotta make this phone go until the next Nexus is out!!
Before everyone starts accusing me of not running a simple search, take it easy, been done. And yet, nothing to help me on the matter.
So here's the thing:
Her phone won't charge. Not when plugged into the wall, BUT when I plug her phone into the computer it is recognized and allows file transfer and everything, but just that - it still won't charge.
Here's what I've found out so far:
- Not a problem with the charger: I'm using the original charger, and it works flawlessly on my own Gnex running PA 4.4
- Nothing wrong with the battery: swap batteries between phones, my phone works fine with her battery, her phone still won't charge.
- When her phone is completely OFF and I plug it in to my PC, it plays the sound of connecting and disconnecting a device, and prompts that it doesn't recognize the USB device. If I tap the power button for a second while it's off (not holding it long enough for it to turn on), it does the same thing connecting-then-disconnecting sounds and "doesn't recognize the USB device".
So - has anyone ever run into this problem before? Know how to fix it? I know the chances are it's just a hardware malfunction, but it's weird because of the ability to transfer files- usually the problem is the reverse.
In the meantime we're using my phone as a charger for both batteries untill we get the spares and wall charger we ordered, but it's a real pain.
Just trying to find a better solution than taking apart the phone and try and fix it or just ordering a new Nexus 5 (which is tempting, but don't really have the money to spend on it...)

Its the micro USB port the pins are bent homie.
Some pins allow charging some allow data transfer. The ones for charging are damaged in your case.
Sorry to bring bad news.

Yup. Just this moment after a really really really close examination of the port and comparing it to my own phone, one tiny half a millimeter peice of metal is bent out of place and broken. Gotta order a new port ASAP and try and change it.
Thanks mate!
But hey, look at the bright side... a fun home project to immerse myself in instead of prepare for my finals! :laugh:

Back with worse news. Just replaced my wife's micro USB port on her i9250 GNex, and.... same thing. Still won't charge, computer recognizes it. Now I'm completely baffled. Thought for a moment that maybe I had been such a fool as to have put back in the old port, but unfortunately, it wasn't my stupidity.
Ideas, anyone?
Hey folks, I have a N7 with some issues. I'm bashing my head against the wall on this one. I bought a 2nd gen N7 with a broken screen from some crook on eBay. He neglected to discuss it's other problems, however this is what I have. I replaced the screen, but even before doing so I found that a USB OTG mouse was not recognized (it works on my 1st gen), then I tried my little BT keyboard, BT wouldn't pair... Plug the tab into a PC and the PC completely ignores it. No device in device manager, I can even go to the port the tab is on is device manager and it shows nothing, not even current draw. The tablet does however charge on the PC, and it for some reason thinks that it is on AC charging, not USB. I have tried this on several computers with almost identical results. On a PC with USB 3 ports though, device manager sees it, just says that the device is unrecognized and may have a hardware problem.
So, I managed to get it to connect MTP one time by slightly twisting the USB cable. I then determine it must have a bad USB port, so I ordered some SMD USB sockets when I got other parts for a different project. I replaced the USB port tonight, and nothing changed, it is exactly the same. No data, always thinks it's on AC. On a whim I tried USB while in the bootloader, and it installs the fastboot drivers just fine and I am able to send fastboot commands.
After finding this, I figure it has to be something software or firmware related, so I flash it via fastboot back to bone stock. Reboot system and still no data connection, still thinks it's always on AC. I'm about at my wits end with it. I know there are other ways to move data to the tablet, but only having access to ADB via wifi is lameo and I happen to use USB host.OTG a lot.
Does anyone know what I am missing? I'm thinking it has to be something in the firmware at a level deeper than most the roms and images go. The PO is had it unlocked and cleanrom flashed. I have since tried AOKP, stock 4.4.4, now PA.
On a side note, if there is no fixing this SOB, do any of you know which of the flo roms have native wifi ADB? At least that will help...
Thanks,
Jason
No one has any ideas? No one else has had this issue? What it seems to me is that it is stuck in "USB fast charge mode" that's the only reason I can think that it would think it was on AC still even when on USB. I have tried three different kernels though now and enabled USB fast charge then disabled it, but it doesn't help.
Is it possible for someone to have put it in fast charge mode and made it stick regardless of kernel changes?
Just looking for ideas. Thanks folks!
Later,
Jason
I have exactly the same issue as yours! I couldn't connect my N7 via USB to PC. Gave me USB device not recognised error. I even fastory reset it. However, one time I did twist the USB cable and my device was recognised and it seemed to work fine during that day. I also managed to flash Android L developer's preview on top of that. The following day I started getting the same issue and haven't been able to resolve ever since. Even in fastboot, my device doesn't get recognised. It's the most frustrating thing ever!
Yeah, it definitely sucks. I was convinced it was the USB socket since twisting brought it alive that one time. However, I replaced my connector and it is the same. I then took it apart again and inspected all the traces and solder joints near the USB connector. I was still certain that the twisting meant it was a physical problem. It wasn't until much later that I found that fastboot worked.
I have done a ton of research trying to find an answer, but most everyone just pawns it off as a driver problem. I have tried every fix those people have offered, but it is never seen by the PC on USB 2, and only shows up as "device not recognized" on USB3. I have tried several different computers, but today I'm going to try an old XP machine. Several people seem convinced these issues are due to Win7. I'll let you know if I find anything.

Try flashing 4.4.2 factory image. Maybe it starts working. For me, issues started 4.4.4+. currently I am stuck on Anroid L preview
Quick update, I asked Scott at Asus if he could give us any ideas, he said base don everything I told him that I had tried that it seems likely that it is a hardware problem with the USB board. I'm still not convinced, but the USB board is going to be my last resort.
Other than that, I tried the tab on a win XP computer and XP sees it as "unrecognized device" says that the USB needs unplugged/replugged and if that doesn't work to replace the device... I would think that the data pins are shorted or something, but mine works in fastboot, that is what has me stumped!
I'll try flashing 4.4.2.
Thanks,
Jason
Well, I just flashed back to 4.3.0 which looks to be the original software for this device. It did not behave any differently. I guess I am going to have to look into a new USB board. The things are expensive though, hopefully I can catch a decent used one for a good price. I'll let you all know if I order one and if it solves it.
Later,
Jason
New board is expensive. *sigh*
Yes they are, and I wouldn't trust ebay as far as I could throw it. I would hate to buy a used one and find out it has the same issue. I have another email into Scott asking if it is possible to buy parts direct from ASUS, and if so, what the board might cost. I'll keep you posted.
Later,
Jason
I heard back from Scott at Asus. They do not sell any parts. He suggested eBay... I guess I will start a saved search and see if I can catch one for a reasonable price. I can't see dropping $80 on a USB board. I guess if it doesn't fix it I could resell it... Still is retarded. This will make what this tablet has cost me much more than a brand new one Damn the crooked eBay sellers!!!

Oh that's awful! I can't believe they don't sell replacement parts! I guess I have to live with a broken N7. I just hope Google pushes official L release OTA to devices running L preview.
I had a similar issue once. Turned out that MTP mode wasn't selected. Storage >Menu button > MTP should be selected.
I think i just ****ed my phone with a simple USB. I wanted to stream to pc so i plugged a usb c into my device and into my pc, then i noticed it wasnt detecting on redmagic app so i unplugged, now my battery status is in green and it has a white lightning bolt by it, and thinks it is charging when it isnt. Says charging 45 days left, accubattery has stupid high voltage, and rebooting doesnt fix it. Do i need to send it back for warranty or something? never had issues with default charger, i just used this ****ing usb c for streaming and now my **** is broken if i shut off the phone it brings itself back and before unlock shows the charging symbol in the middle. Please can anyone help me ill take any suggestions
Maybe the charger is the problem.
Always check the charger.
At when moment do you notice this problem ? After installing an app ?

all i did was take a usb-c in my room, plug it into my pc to stream, nubia app didnt see it, so i unplugged, now im screwed.
my default charger never had an issue, all i did was plug in a usb-c into the pc as the app states, now high heat, drain, and i cant charge because it thinks its charging
So use another one

i dont think you read my post, since i plugged in that usb to my PC TO STREAM, NOT CHARGE, i CANNOT use any other one, because android thinks it is charging without ANYTHING PLUGGED IN. If i plug in a charger, nothing changes, because android already thought it was charging
Is the PC recognize him ?

Maybe the port got damaged? Try to clean it first if possible using an ear swab dipped in rubbing alcohol with the device turned off and let it dry.
If it's a damaged port, may need to be repaired.
If yes, do a factory reset.

i just did a factory reset and it's still broke, so i think plugging usb into computer literally ****ed my battery.
Thanks for trying to help but ig i need to use warranty. Bull**** really, because they never tell you specifically what to use, just a usb-c, now im gonna be out of a phone because i tried to use a feature.

Do you understand what power surges are or what improperly plugging in a cable can do to a port of a mobile device?
For example: Too much or too low voltage can damage a port to the point the device will think something is there, when it isn't. The same goes for damaging the pins when you plug the charger in.

my friend was saying something similar, but was originally going more towards "android got drunk, reset"
but sadly that didn't work. So im assuming plugging in a usb-c to my phone to my pc literally ****ed my port/battery. I didn't SHOVE it in, i plugged it in as i would my normal charger.
if voltage is the case, i find it very unfair they don't disclose this in their streaming app, it simply says to use a usb-c and that is what i did, now im paying for trying to use a feature of a device i paid for.
already shot an email to support, and have a backup phone in the meantime.
appreciate your response, backing up one of the theories of why its now screwed.

"stuff" happens, it's unfortunate but technology is known to go bad randomly without explanation. Best to get it repaired if you still have warranty. Otherwise, upgrade the phone to something newer. It's just bad luck.
Sometimes people buy cars and they break down within a few months.

Did you try the rubbing alcohol cleaning? I had something similar with an ipad, the USB c cable broke a couple of the female port and it ended up screwing the whole thing, as much as I want to advice anything, it ain't a software issue but a hardware one, the only option I see it's cleaning the port and trying to "scrap" any debris that might been left by the other cable, If that doesn't work, then yes, use your warranty asap

i didn't even think of that, but if i were to do that, wouldn't they then use that as an argument of why it stopped working? "oh well you put cleaning alcohol in the port, of course its gonna break idiot" etc
i have some of https://www.amazon.com/CRC-05101-QD...prefix=crc+aq+elecronic+cleane,aps,104&sr=8-2
that, i used it before on electronics, it says its safe for electronics and i used it to clean my weed pens before, but i really dont wanna try to clean it if it can be used against me later. It also doesn't APPEAR like anything is on the connector, but who knows right. I just dont wanna try to clean it, then have them blame me and refuse warranty because i tried to fix it, even amazon said with what i said, the device is defective, so idk maybe i will try

i dont think port is damaged, i think voltage from my pc to phone was so high/low that it totally ****ed the battery or port.
once again, all i did was take a USB-C CORD and PLUG IT INTO MY DEVICE, took the other end and plugged into USB, i see nubia app doesnt see phone, unplug it, and ****ed.
has to be electrical, nothing else makes sense for what i did, the only cord they give you out of the box is a 65w usb-c to usb-c, had i a proper cord from usb-a to usb-c i wouldnt be in this situation
https://imgur.com/RD7c0LV
i did what it said, and now im paying for it. Given the fact there's no way to change the charging method/wattage/voltage in the system, i feel they should at least specify what TYPE of usb-c cord to use, because im just a normal user who wanted to stream to pc, and all because i simply did what they said, I'm out of a phone. Ridiculous.
im convinced the voltage of device + too high/low voltage of port, screwed the battery up, and now it thinks its always charging, and says 45 days left till full charge, does this not sound like a problem from electricity? i did NOTHING ELSE, this is the dumbest thing i've ever had to deal with, all because i plugged in my phone to pc
