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

any update? i'm having this problem aswell. my phone wont charge through the wall charger but will when connected to a computer... but when it's connected to the computer it says that my usb device (phone) has malfunctioned.
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

Hi,
my usb connection is pretty screwed up, it only charges and windows doesnt recognize the device anymore, It says the device malfunctioned ... ODIN doesnt recognize the phone anymore also. I would like to know if there is a way for me to return to a complete stock version of my phone for warranty purpose without a working usb connection. I have a Telus version of the sgh-t989, and tried with different computers, different usb cables, bought new samsung oem cables, but nothing works, and it used to work before.
Also I saw in the market this Mobile ODIN Pro witch can do the same tasks as the pc connected ODIN. Overall as good feedback but some reviews I saw stated the it messed up the phone and needed regular ODIN to fix it, and thats currently not an option for me.
My phone as CWM recovery and is rooted.
Any suggestions?
Thank you.
Have you tried uninstalling and reinstalling the driver?
Edit: the usb driver found here: m.samsung.com/us/support/downloads/SGH-T989ZKBTMB
Sent from my SGH-T989 using XDA
Yes, even tried on a clean windows install twice,
After all your troubleshooting I'm inclined to think you have defective hardware

I saw somewhere, this zip file that you flash in CWM, its called ''SGH-T989-UnRoot_ROM_Zedomax.zip'' wich unroots and restocks, but its for t-mobile, wondering if there is such a file for telus maybe
Im pretty sure as well that my problem is hardware, since it used to work without any problems on my 3 computers, and now doesnt.
My phone is still under warranty, thats why I want to bring it back completely stock to get it fixed or replaced.
I love this phone, and is in mint condition besides this usb problem
Does the USB port on your phone seem solid? No jiggling etc? Dust free? With you trying different cables and computers with proper drivers its probably safe to assume your phone is the problem...have you verified those cables handle data? I've seen some cables that just supply a 5 volt charge...
Sent from my SAMSUNG-SGH-T989 using XDA
I tried the usb cables with other phones, and there is no problem with them.
I cleaned the usb port at the bottom of my phone with a dry toothbrush.
The port itself is solid but not like it used to be, if I wiggle the cable while its charging , it will stop charging until I put the phone down and stop moving it, then it will restart charging again.
Im pretty sure the problem itself is the port, thats why Im looking for a solution the get back to stock , so i can get this fixed before the port stops charging the phone also ... And then Im really screwed
So after several weeks trying to figure out what is wrong with my device I came to the conclusion that the USB port on my GNex went bad
here's a few reasons why:
-GNex No longer chargers when plugged in the wall outlet tried several OEM and non OEM USB cables
(but will somewhat charge if the phone is turned off but very slowly and has an error) It shows the battery icon then
it will flash twice the battery charging icon then back to the battery icon with the bolt in the middle and will do that through out the night.
Had a custom rom on there tried changing roms but my computer no longer recognized it and so i've installed removed various drivers
and tried different PC ports and nothing would let it recognize so I manually download a rom on the phone but it wouldn't install.
So I was finally able to odin back to factory stock but that still didn't do anything not only I can no longer go into recovery because it seems to
not have one so I'm stuck and it's getting on my nerves because the only way I can charge it while it's on is plugged into the computer.
I'm my money is that USB port on the phone is malfunctioning so I'm trying to relock the bootloader but can't find a through the terminal, because ADB does not work. Technically the phone still has manufacture warranty. So any help would be appreciated. Thanks guys
Does your computer recognize it in fast boot?
Sent from my Galaxy Nexus using xda app-developers app
I had the exact same issue with an old T989 (T-Mo SGSII). Same symptoms and everything. What got me through the insurance claim was that I told them that the phone was doing an OTA but somehow it failed and it was stuck at the ODIN screen. What really happened was the USB port gave way while restoring to stock which caused the soft brick, but after that the USB port was completely nonfunctional. Try re-positioning the USB cable, the port might be making bad contact with the pins. Other than that, I would just ship it as is since they hardly check that the phones are rooted or in your case, an unlocked bootloader.
No it doesn't recognize it in fastboot or anything it says unknown device. As far as sending it back in I've been on the samsung website trying to request a service repair, but I've also purchased the phone on CL. But I didn't have a problem with it for several weeks so I know it really wasn't a defective unit. Yeah, I thought about reposition the USB cable to no avail.
I didn't think about using that... how did you manage to get an RMA or something to get it replaced
So you can use the device itself fine? Cab you go into play store? Download booot unlocker . it locks/unlocks the bootloader from the phone itself

My apologies if it was in the wrong thread. Yes I'm able to use the phone fine and everything it's just the charging and recognition that's causing problems.
Another question what do I need to be able to open a repair request from samsung or how do I go about it. went to the website but all it does is take me to FAQs?
Well unfortunately boot unlocker won't work because I don't have root and I can't root my phone through ADB or anything like that because like before PCs won't recognize phone at all unless there is a method I can use through the terminal editor
I don't want to hi-jack your thread, but I am also having a similar issue.
I am running CM 10.0.0 but the cell phone will charge, but will NOT connect to the computer. I have tried two different cables and on 3 different USB ports on two different computers. I have the Samsung drivers downloaded and installed. I did not have this issue before the unlock/flash of CM. Is this is a known issue? Is there anyway around it?
I'm starting to think its a USB port issue
If it hasn't been said before, this is a very common problem, it even happens with a few Samsung phones. It's not software related, all hardware, the micro USB port is lousy.
Unless you want to work with Samsung, who, based on my experience, will probably want to charge you "because you broke it", there's the incredibly hard-to-find Pogo Dock or the inductive charging mod, which is actually kinda neat I may do that, I already have all the touchstone stuff...
There's also DIY replacement of the USB daughter board or whatever the exact term is.
In any case, Samsung *might* help you, for a decent fee and 2 weeks' (or more) time.
Yes, try to analyze USB port pins for damage, dirt, bent, anything that can cause a lousy connection (or none whatsoever)

Yeah, I mean I would have to figure something out because I can't transfer files and the only to do it is to upload them to the cloud which is not optimal and real pain.
well out of nowhere USB starting working and charging now normally. So that's cool I'm glad now just to wait till ubuntu comes out.
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.
Hi,
I need to get back to Stock on my current Samsung Galaxy S9 (SM-G960F) running LineageOS 15.1 Custom ROM. The TWRP backup I made before flashing LineageOS seems to be corrupted, because I get a bootploop every try after recovering. The second problem is, that my USB port is not working anymore while connecting to a Windows or Linux PC. The battery is charging but no device is recognized in the device manager or anything else, although my other Samsung device with the same cable works fine.
So for getting back to stock firmware, I only found guides and ROMs using Odin to flash via USB Cable, which is not an option for me. The only possibility is recovering via TWRP and a SD card, but I don't have a working backup with Stock the Samsung Android.
Does anybody know where to find such an Stock Samsung Android TWRP Backup, or can Updload it if they have one? Or is there another possibility to flash the original Samsung Firmware with a SD card and TWRP?
Thanks in advance and best regards,
John

Make sure there isn't any trash in your Port. It can play hell on usb connection. Type c ports are notorious for collecting daily lints and dirt and getting packed in. Would be where i start

He said it was charging. At least on pc is what i got out of it. These usb type c are so much bigger than other versions. That when it's in your pocket you get your daily pocket dirts in it. Combines with minute amounts of moisture or sweat. I know of i leave mine in my pocket. In the summer. Me screen will show signs of body sweat on it. So i just assume the port or moist lint and junk get in. Them you cram that big ole plug in. Mashing it it. Day after day it gets solidly packed in. Not allowing the connector to go in all the way. Ive had a few ive got so packed in its taken several cleaning attempts. And works like new. And it seems to be a common going thing. I actually use type c rubber plugs in mine. Usb savers.
Damn shame these don't have odin over WiFi like the gear watches. Or they may and i just never tried
