[Q] USB Connection

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

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...

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

Am I screwed? (Phone won't charge_

So last night (TY Ambien) I decided to use my Logitech Harmony cable to charge my phone... Minutes later the phone kept going in and out of charging mode and now currently will not work at all.
Anyone have any idea what I could possibly do to fix this? No experience with this kind of thing.
Thankfully I forgot to cancel my crap insurance through verizon a few months back and just ordered a new one just in case. Will they say anything about the fact that the phone is rooted?

Don't panic just yet. I have gone through 3 cables already with my Nexus. For some reason micro usb cables get real loose real easily in the Nexus. I have one from Verizon (desperate and paid too much) that fits in there very tightly and always works. So just try a new cable and make sure it has a tight fit.

I actually had the same problem and they sent me out a new one cause I said it was the phone.. I went through about 4 or 5 cables...
Right now though even with the correct cable that's been working fine I can't get any kind of charge.

If I screwed up the connection there's nothing I can try and do to fix it?
Also if I end up having to get a phone should I note use the current verizon cord I have if it's been pluggd into this phone?

I have a nexus and a harmony remote. AFAIK there is nothing special about the harmony cable, it's just a usb cable. The only device I have that has a different cable is my Nook. Guess what I am saying is that I don't think for sure that the cable caused your problem.

If I can't get it to connect to the computer to unroot it though I'm pretty much screwed anyway since I can't send it to verizon rooted right?
Any suggestions on what I could do to see if I can clear it up on my own if it's not the connection?

Unless you can find a way to transfer stock rom files over the network to your usb and flash it from there, but I am not sure if you can lock the bootloader that way.
As a last case resort, I am not advocating this by any means, if your phone let's say weren't able to boot up or turn on at all then verizon wouldn't be able to say it's been rooted, right? I read of a guy who messed up his so bad it would just boot loop and he couldn't even get into recovery. He just took it to the store and played dumb.

as odd as this sounds, get a cocktail stick and push it down onto the left most pin of the usb port (on phone) apply a bit of pressure and then try charging again.
PjFlo.

Update - Found my standard battery and popped that in... Phone works, when you try to charge it, it says charging but does not charge and goes down if being used.
Any ideas?

You can transfer them over wifi.

Both of my batteries are totally dead now. Looks like I'll be giving asurion $100. Ugh.

[Q] Computers No longer recognize device no more recovery

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

Thanks
FNM

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.

Problems with my USB. Please diagnose...

I had an account here but can't remember my old email info. Anyways. Problem I am having started last week. I have a rooted galaxy nexus running 4.3 Jellybean vanilla. When I insert the usb cable for charging it does nothing initially. But after say 15min or so it will display charging on the icon. Or if I plug in the usb connector and reboot the phone it would charge immediately. It worked like this for a week until I decided it could be a software problem. I wiped the phone completely with TWRP with plans of installing everything on a clean slate. Problem is I can't get it to appear in windows. "USB device not recognized" and no matter how I install the drivers I can't get the thing to connect to my computer. a few days ago I was able to copy some files onto it but now nothing. So basically I have a phone with only recovery software on it and have no way of flashing a ROM back onto it. I am just wondering if this is a motherboard problem or a problem with the usb connector. Anyone have similar symptoms? Right now this thing is a brick and not in a position to buy a new phone a the moment. I am pretty handy when it comes to fixing things of this sort. I have tried cleaning the port out with a needle. Also have tried bending the connector back out to the center. Phone is a GSM Galaxy Nexus from Canada. Thanks for your help in advance.

no USB recognition

Hi.
After searching and testing for hours I don't know how to proceed...
I can't access my phone via USB anymore. The phone isn't detected, no change in device manager on Win7. Only Win8.1 says it found an unknown device.
Quick Charge also does not work like before, but normal charging works stable on every cable.
On the phone, no connection info pops up. I had to set MTP in the developer settings. But it does the charging vibration.
Some testing before, the device was detected in about 1 of 10 tryings, but only with the original cable.
But now, this also doesn't happen anymore.
It worked for about 4 times in a row, after I flashed a 20g flashable kdz over the 20d, but stopped working then.
Could the method that activates MTP functionality be corrupted? (in download mode it also doesn't work)
This all happens between updating to mm and now.
The phone is unlocked and rooted. I use an extended battery and a SD card. A reset didn't help.
The pins of the port look ok. None of the solutions I found did help.
Could the controller or parts of the port be destroyed?
Could my Aukey QC 3.0 car charger do some harm to the device? Maybe when being connected while starting the engine or something like this?
Is the warranty for hardware problems like this void when unlocking the bootloader?

Don't know if that will actually help but just give FWUL a try.

This is a live ISO where you don't need any drivers etc. If you have a physical defect it will not help but to exclude windows + driver issues it's worth a try

I gave that a try but it didn't help.
I am totally confused, which type of (bad) usage could result in such a behavior...
It also do not detect my Flir One thermal cam anymore.
How can I figure out if it is based on soft- or hardware?

im having a very similar issue with my g4 , it charges very slowly and shows charging from a USB source instead of AC when plugged to a charger, quickcharge stopped working, and my pc wont recognize it.
i think the problem is a damaged usb port

Today I was in a repair shop for mobiles and the guy heated up the internal pins of the usb port with a soldering iron to exclude a problem with the connection there, but it didn't help.
Next would be to electrically meassure the external pins against the internal pins, to be sure there is nothing broken. But I think, I will send it to LG to check the device for the concrete issue.
The guy at the service said, it could be that some of the flashs did destroy the function which calls up the data connection and that they can do a complete reflash without using the usb port.
But... he also said that the diagnosted issue could be out of my warrenty due to the unlocked bootloader.
If you want to exclude the usb port as a problem, it is quite easy to change the usb port for someone with a good soldering equipment. The port itself does only cost a pocket money and there are some detailed videos on youtube for this. good luck ^^
