Problems with A/C charging please help!

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!

Desire not charging, LED is on, USB storage works

As the title says, my desire is not charging it seems, or if so VERY slow so it does run out of battery after a night when plugged in to AC adapter.
I can use USB storage when the phone is on, so it isn't bricked? One thing is that the miniusb connection seems to be bad, I need to push the cable hard, to get it connected.
Anyone recognize this at all? I have never had these kind of issues before. The phone came back from repair some months ago, changing mainboard, and have been working good until now

[Q] Nexus nonchargeable, starts smoking(!), still turns on

Hey guys, I probably have a pretty unusual question or rather observation. Sometime yesterday night when I connected the Galaxy Nexus to the power outlet it started to make a crackling noise. I immediately disconnected it but it already smelled like burnt plastic. As you can believe I was pretty shocked! Trying to turn on the phone worked flawlessly though, so I though, OK might have been my outlet and tried two different ones. Still to no avail, the phone works but won't charge.
I turned it off for the night and waited until the morning to try to connect it to my computer (thinking maybe it's the plug that's broken) and reset it to factory default. Big mistake! Windows pops up with a warning telling em that it detected a power surge on one of my USB ports, resulting in my phone still not charging, the USB port being broken (won't recognize my USB key anymore), and and the Micro-USB connector emitting some smoke after I unplug it from the Nexus.
Now, enough storytelling. Maybe you guys can help me with the mountain of questions I have after this episode:
A) Really, what happened here? I don't think it has something to do with the software side of it, can it? (eg Battery overloaded?) Then I would guess more people would have had the same problem... I'm running AOKP M3 and Franco Kernel 3.0.08-M1.
B) Did anyone have the same problem?
C) I guess it's unfixable from a software standpoint, so my only option would be to send it back to Amazon and hope they replace it. Any other ideas? I bought it at Amazon.de (Germany) but due to it having AOKP Rom and Franco Kernel installed getting a replacement might be difficult.
C) How do I get my USB port functioning again? It's a new notebook but I don't want to send it back for repairs as I bought it in Hong Kong (I have an international warranty though.) and need it to write my Thesis.
Update: Uninstalled and re-installed the USB drivers, that fixed the USB port.
Thanks for your time and hopefully help!

A) Sounds like a short circuit somewhere. My guess would be the connector or close to it.
B) I certainly didn't but I'm sure it's happened to someone.
C) Unroot and Relock and send it back to Samsung if Amazon doesn't take it back. I'm not sure about their return policy since it's a cellphone that is under warranty. May also depend how long ago you bought it.
The more I think about it I wonder if it's just the USB cable... Since you said the smoke came from the Micro-USB connector... Plug it back into the computer without the phone and see if you get the USB power surge thing again. There may just be a short in the cable.
Of course checking it with a multimeter would be safer, do you have one of those?
Or do you have another Micro-USB you can try charging the phone with?

The problem is that I can't even unroot it since it is not being recognized by the computer (and I get the power surge warning). I will try with the new cable, and then send it back even if it works. might give me problems further down the line if I don't.

I don't have a different cable (or multimeter) near me at the moment but will give an update as soon as I do. I didn't get the power surge warning when I just plugged in only the cable, but as there is no source that could draw power that seems likely to me.
P.s.: Just bought it in january so generally sending it back shouldn't be a problem - if I can get it unrooted.

Well that's "good" in that we know the cable isn't shorted. I thought maybe some pins or wires were touching inside the cable that would cause a short (+5VDC and GND) even without the cable being plugged into anything.
So it does look like the fault is in the phone somewhere... And that could be just about anything.
Being that it's Amazon they probably will just replace it and not even bother with checking for it being rooted - especially since you can say it's smoking. As far as I know only the carriers will turn on the phone and look it over (not to mention most Amazon employees wouldn't know root it it reached out of the phone and smacked them across the face). Other 3rd party stores just mark it as defective and put it in a box to send back. I'm not sure how Amazon's return process works though.
I had several problems with my EVO (speakers mostly) and had it rooted when I took it in. They just fixed it anyway and even told me they liked what I had done with it a few times.

Hey, just to give an update I didn't get a specific explanation but Amazon replaced the battery, cable & charger. Now its working again. No problems with it being rooted, they even left rooted but installed stock android & kernel.

I'm currently having this problem, i called google, and they transferred me to samsung. And their department that handles this issue is closed on weekends

because of that "malfunction" i cant revert back to stock everything and relock everything to get it repaired with bell mobility.

when i sent them my phone i couldn't bring back to stock software but i still shipped it out either way, i actually got an email from samsung today saying a component has been replaced and being shipped out back to to me, so i guess they fixed it with it being rooted, so when i receive it ill let you know

Well I got back my phone today and its charging again. But they restored my phone back to factory setting. So I lost all my pics and phone didn't restore previous apps etc but oh well as long as they fixed it and no questions asked I'm happy

[Q] rooted sch-r980 lost USB, charger, and ALL sound

I picked up this US cellular sch-r890 that was never hooked up to play with. I put an SIM card in it and it rejected it. Anyway I wanted it as a tablet and didnt really care if I could hook it up as a phone or not and rooted the phone. All went well except now I have zero sound on it at all and the USB does not recognize anything. nothing from a wall charger either...However, it does respond in ODIN mode???? and I am able to charge it when the phone is turned off and plugged into usb. It cycles blue battery.. green battery...vibrate....repeat cycle, but it does charge it. I have tried several mods and NOTHING has changed my usb connecting. and yes USB devel is checked.. currently have it KK 4.4NIGHTLY and EVERYTHING runs fantastic....except USB/SOUND!!.
Any and all help with this would be appreciated. This would be a great lil gaming machine if it had sound.....and headphone jacks dont have sound either. its not a setting

also.....before I did all that I called straight talk to hook up the phone and they wouldnt do it....then I called US cellular as its their name on the phone and they said to go into the store in which I did. They ran the meid# and went in the back whipsered back and forth and said they couldnt do anything with it and didnt know where I got such a thing and should get my money back. $50 on craigslist explains a lot!!! lol. So I decided to beef up the lil tablet for a toy and the FN SOUND is KILLING me.

[Q] a BRAND NEW kind of charging problem

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.

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?
