My Epic wont get recognized by any comp

Would appreciate it if someone could tell me how to fix this. It was always a problem my or any computer i used would never find my phone when i connected it via USB. I always got something saying usb port malfunction and when i go to my computer phone never shows but phone does charge through the usb so it is connected. Any help here would be appreciated.
P.S ive tried about 5 different usb cords and atleast 5 different computers even ones on campus

Take it to the store...

Get a new cable...a heavy dudty one like a Blackberry or Palm. It takes nothing to charge through the cable but a lot to pass data.

.. i had same problem: tried many cords, comp, reinstalled drivers, etc.
Finally i odined the phone as if it was bricked and all was well.
To make long story longer.... initially my comp would ID my phone great, (I rooted, mass storage the card,etc). but i took the phone to Sprint for other problems. I dont know what they did but my comp did not recognize my phone when i got it back, no matter what i did.
Odined the phone and poof! everything was back to normal.

[Q] No power no nothing

I need some serious help. I just got this phone and was getting ready to root it and here is what happened. I opened up odin, unchecked f. reset time, put victory_8G_100528.pit in pit according to http://forum.xda-developers.com/wiki/SPH-D700-ODIN, then added stockdeoEC05.tar.md5 in PDA. Hit start and the screen said something about partition, the phone shut off and nothing since. I can't even get a charge. The phone has no life at all.
Please help

Try leaving your battery out for 30 min and see if you can get into download mode with usb plugged only. Also, check this thread. Its a guide for bringing a semi bricked epic back to life.

Also see this for the most current one click root and revovery with cwm 3.1.0.1

Take the sd card and batttery out, and plug in the charger llike this but while holding 1 and the power button at the same time

You rock!
Phone is in downloading mode and I'm downloading the tar from the link you gave me. Any idea what happened so I don't do it again? This was my first time using Odin so I'm not familiar with it. Did I set it up right? I have to learn from my mistakes and I promised my mom m Moment, which I had to reactivate just now. Geez Laweez...

Glad to hear it. I would buy a better usb cable for the future if you are still using the stock one.

The factory usb cable is great for charging but nothing else. You need a good cable for data transfer. I always use my old Blackberry usb cables they are awesome, BB depend on a lot of data sync with the computer their cables are great.

Here we go...
Okay now I can't get the pc to recognize the device. I tried the drivers from the pack ont those links you gave me prior, and even tried some others. Swapped 3 different usb cords too BTW the only thing it will do is go to download mode by taking battery & card out, plugging in usb while holding 1 & power.

Did you reboot your computer after installing the drivers?
Sent from my SPH-D700 using xda premium

Yes I did. Still have the same issue. Last time it worked was when I used Odin and the phone never rebooted. That's what started this thread.
I'm trying to see what happens when I try this on my desktop... Will update soon...

Drivers not working
Even when I tried my desktop (XP, laptop Win 7) I got the same results... Device not recognized...
Even when I click on there was a problem with the device message and go to update driver, it tells me there is no driver installed or needed for this device. I'm hopeful this can be fixed but I can't get the device to be seen and it's stuck in downloading mode. I have searched all the forums and haven't seen this issue yet. Does anyone know how to fix this when it only turns on without the battery in while plugging in the USB and holding 1 & power? I had issues with the device being seen before this happened but man I'm lost as what to try. I even tried the one on the samsung site... of course uninstalling the previous ones and resetting the computer before my attempts.

Are you using the usb ports in the back of the computer that are directly connected to the motherboard?

Phone is reset!!! All is good!!!
Now everyone said to not use the usb that came with but you know what... I went to work and grabbed it and it worked... Phone is getting worked over as we type...

I would suggest buying a new cable and trying that. Seems a lot of users are encountering this lately. The wires that carry data fail, but the wires that carry power still function. It doesn't have to be a Samsung branded cable, but one specifically for charging/data for the SGH-T989. It happened to me both on this phone, and my Transformer. Both times it was solved by using a new cable.
Your local electronics store should carry what you need. Good luck!

I tried it. No help :/. I think it is the phone's usb port that makes this problem. Probably I'll send it to samsung company to have it fixed.

Before u diagnose the phone as the issue i would check and try plugging it to another pc besides the one that doesnt detect it because i have the same issue with my main pc. When i plug it it opens up as an unreadable drive, it wount open or anything, but when i plug it to my laptop it works perfect.
kind of wierd but it works. i also tried installing kies and didnt help at all. now it it still doesnt work than yea probably the phone.

Yah, it's probably the phone. I tried plug it in my brother's laptop and computer (Kies installed) and still nothing happens.

Allgamer had a similar problem. Turns out it was his cable

Try the free wifi explorer from the marketplace.

Also remove sim, sd card, and battery for a bit then replace. Also, get the most "official" cable you can. I'm working with an old evo cable and an old g2 cable. Some of the car charging ones/generics won't play nice. Try blowing (light laughing allowed) into the port.

Finally!!
Ok here is what i did:
1-enable EHCI on your computer from device manage >> http://www.intel.com/technology/usb/ehcispec.htm
2-took a portable toothbrush with isoprop (swabbing alcohol)
3-took my phone to the gas station ...25c air and dried the crap out of it
4-wipe/reset my phone from fast boot menu (not android menu)
5-got an LG "B" data cable...
voila monsieur !!!! i dont know which was the silverbullet but i aint complainin.
However, it was still nice to know that Samsung is a no questions asked manufacturer.
Someone was having the same issues as mine in russia, and he said ICS 4.0 did it and is waaaaaaaaaaay better for this phone. Im gonna give this to a friend and WILL NOT touch these till ICS 4 officially comes out here. Tooo much hassle and ive got too much info riding on it (phone). <<personal opinion

please help - USB not recognized

Hello,
Please help me. My phone will not connect via USB to a PC. Steps I have taken to try and solve this so far:
- Tried 3 different USB cables;
- Re-installed Kies, Samsung USB drivers, Android SDK google USB drivers, etc
- Turned USB debugging on/off
- Turned Allow Mock Locations on/off
- Tried USB Utilities, tapped apps, etc.
- Tried *#7284# dialpad trick
- Tried 3 different computers (all running win 7 64 bit)
- Unmounted/remounted USB in CWM recovery
- Flashed 3 different ROMs (jedi mind tricks, clones n drones, darkside evolution)
- Restored a nandroid backup from when it was working;
- wiped cache, dalvic cache, factory reset, etc.
When i try to mount usb in CWM it says "E: Unable to write to ums lunfile (No such file or directory). Yesterday it was not charging over USB, now it is (flashed darkside evolution ROM this morning).
Current setup:
Android: 4.0.3
Baseband: T989UVLE1
Kernel: 3.0.8_SGH-T989_DARKSIDE.VENOM_02+
Build: DARKSIDE.EVOLUTION.3 v7
If anyone has any ideas I would really really appreciated hearing them. I have been searching and trying fixes for the last couple days and i'm about ready to throw my phone off a bridge.
Thank you!

USB port is shot. This is a know problem with this device. The device will be able to charge, but will not be recognized by the PC. Had the same issue with my wifes phone and was unable to root. Half the time, it wouldn't even charge using the car charger (though the wall charger always worked).
Called TMO and received a warranty replacement. They charged $20, which they later removed when I called and asked them to.

Thank you, at least i'm not crazy!

Yeah for some reason. It looks like a batch of phones have a usb port problem. I assume the phone is newer than February? Because it seems there are a lot of this problem including the power button surfacing on the forums as of late

It is an older phone, purchased last fall right when it hit the shelves. I actually took the thing apart last night and noticed that there was some water damage, it spent an evening outside earlier this year but I hadn't noticed any issues until this weekend. I cleaned some corrosion out of the USB port out with an old toothbrush and bolted it back together, fired it up and everything seems to be working again. Wonder how long its gonna last?

[Q] Problem with OTG

Hi, I am having a slight problem and am at a loss.
First of all, my phone is stock. I bought my OTG cable a few months ago and it worked just fine. I was using it to play games with my PS3 remote. However, with less time on my hands, I put the games aside and with it, I was no longer using my OTG cable.
Whenever I plug in the OTG cable, nothing happens and I don't get a notification that a USB device is connected. I have confirmed that it is not the OTG cable as I have tried it on 3 other phones, all of which responded to the cable connecting.
I am not sure when this problem started happening, but I didn't notice until yesterday when I was trying to use my OTG cable. In addition, when I plug in my phone to my laptop, my phone doesn't give me the option to turn on debugging mode. Again, I don't know when this problem actually began. I mention this because I am not sure if it is relevant to my OTG cable problem. Yes, I have checked and debugging mode is enabled.
I am not sure what to do and I have scoured the web trying to find a solution. Maybe I am searching in the wrong places, or maybe I am not just searching correctly, but I figured that my last option was coming here.
I thank you ahead for your time and hope that a solution can be found. I will be more than happy to provide any more details of needed.

Sounds like a bad USB port. You can replace it yourself, or do a warranty exchange. I don't think it's software related but try factory resetting. Or another ROM.
Sent from my SAMSUNG-SGH-T989 using Tapatalk 2

It sounds similar to what my phone was doing a few days ago. I don't have the OTG, but when I plugged my phone in to the computer, it only went to charge mode and didn't give the USB options, and the computer didn't recognize it at all. I ended up flashing back to stock rooted and it started working again. I flashed CM and then AeonFluxx again and it continued working, so I assume that it was either an app I had installed or something extra I had flashed. Either way, it's working now.
TL;DR Try reflashing before you start tinkering with the hardware, that fixed a similar problem for me.

Alright, thanks guys.
I think I am just going to do a factory reset.
I am able to charge my phone just fine and it connects to the computer just fine as well (Heck, I can do what many others can't....connect to Kies). I have no problems with data transfers either.
So I assume this is a software based problem.
...I may as well root while I am at it....
Haha, I will tinker around a little bit more before I do a factory reset and come back with my results.
Thanks again!

Are you using a kernel with fast charge?
Never mind. You are not rooted so that is not the issue.

Well, it looks like the factory restore didn't solve either issue. So I ended up calling it in and hopefully the replacement phone will work. Gonna have to wait a bit though...GS3's are currently on back order.
Thanks again for the advice though guys! Appreciate it!
