Help connecting Epic to pc (yes I used the search and my issue isn't resolved)

Ever since I rooted I can not get my Epic to connect to a computer period. I'm about to give up and just deal with what I got, hopefully someone can tell me what I'm doing wrong. Before anyone decides to be a smart ass I have used the search function literally for days and have tried tons of things recommended with no result. I am the first to admit I'm an idiot when it comes to anything involving computers but I'm pretty determained to learn.
This has to be the phone because I have tried to connect to 2 desktops (1 running Windows 00 and 1 running the most updated Ubuntu), and 3 laptops (Windows xp, Windows Vista and Ubuntu). When I rooted I used the Vista computer and connected fine (can't anymore). I didn't have the space on the C drive to install the Android SDK so I switched to Ubuntu (first time user btw lol). Somehow when I was backing my SD card I lost any access to it or the notification bar. I never got my SD back til I rebooted but I haven't been able to connect to any PC since. When I charge (even in the car) it always tries to stay in mass storage mode. I basically charge in my car with my phone off hoping it will just charge and not mount my sd card to my car or wall lol. Yes I wiped 3 times, partitioned sd, tried several different cables (but my husband used mine and no problems on his Motorola) I'm sure I've done something wrong when I rooted or mounted to Ubuntu.
I also can't use adb. I followed the directions to the t (a few times lol) but when I run any commands it says "no such file or directory" I didn't have adb on the windows pc when I di noobnl's one click so I never ran the (adb shell ect) commands. I now can't do jack. I am now running noobnl's DI18 ROM with modem.bin flashed thru Clockworkmod.
I have tried all the basics you will find wit 2 days of web search.
My goal is DK28 (dream on Erica lol)...Thanks for any help and for anyone sparing me a lashing ;-)

When you plug in on your windows pcs...in Device manager..do you see anything appear? also do you have USB debugging on the phone?

USB debugging on?
Have you tried reinstalling the drivers for the Epic?
Rebooted phone and PC? (Sometimes it helps)
Used Odin?
Something might have been screwed up during one of your downloads, bad file maybe. Try reinstalling your drivers first, use Odin (phone must be in download mode), and see if it recognizes te device. If it does then Odin the stock .tar file and go from there. It'll give you a fresh start.
That's all I can think of right now.

I bet your USB debugging is on since most root's requier it. Even tho it says connect to pc if usb debugging is on it wont connect to my windows 7 box

I would suggest, if you're really having this many issues, just boot into download mode (1 on the keyboard + power button) and odin back to di18.

Just for kicks have you tried Settings > Privacy > Factory data reset? I assume that wiping does the same thing if not more but it's worth it to see if it somehow resets a setting that might be the issue.
What's left - software issue or Hardware issue.
Software:
hmmm...yeah gotta try connecting through Odin which uses downloader mode instead of USB modes...
Can Odin see your phone? Run Odin as admin with antivirus off, and proper samsung drivers installed. Then boot phone holding down 1 key into downloader mode. Connect to computer through USB port on back of computer (i.e. directly to motherboard) - does Odin identify something attached to USB port?
Yes - flash the dk28!
No - with Odin still on, unplug the USB cable, pause, and reconnect it. Still No? Try a different USB port on computer. Also try uninstalling and reinstalling the drivers - be sure to reboot the PC. If still No, then try on another computer, and as you did before, try different cables. Still No?? --> hardware problem with phone.
Hardware problem with phone: Look at the usb port in the phone - is there any junk in there that might interefere with the connection?
Yes - clean it out
No: phone perhaps internally damaged:
Solution for hardware damage:
You and husband clean up and go to sprint store.
At store - tech will know phone is rooted, so:
--Tech more likely to like you? You handle it, maybe even blame husband. Husband can silently attend and look sheepish, playing the part of 'me man, me dominate environment, me break fancy tech of wife, me sorry." Try to get free replacement phone while simultaneously promising never to let your husband root the phone again, or even touch it.
--Tech more likely to like husband? He goes alone, cops to the true story of how you rooted it and then was backing stuff up when it suddenly stopped working [truth from men? so sincere!]. Try to get free replacement phone while simultaneously promising not to let you in the house should you even attempt to root again.
P.S. forgot to add you might turn off the PCs firewall while testing, as well.

same here. I tried out the free tethering app the other day and with usb debugging on i coudl never get it to install the proper drivers. Without it on and the 64bit drivers installed Odin worked just fine.

I have seen many Galaxy S devices not connect to a computer because of a faulty USB cable. Had my girlfriends sister switch out 3 Vibrants only to accidentally try and connect it to a laptop with a different USB cable and I've seen two others not connect with the stock Samsung USB cable.

How I fixed the tethering issue
I've had the same problem with my galaxy s - connecting to the PC (Win7 32bit) just doesn't do anything. As a test, I had a friend with the same phone/rom (froyo, rooted) connect - and he was able to! It installed the drivers and it just worked. He disconnected, I connected, and now it's fine.
So, see if you can find someone with the same phone and see if they can connect. Makes no sense to me, but it worked.

I've had my Epic fail to mount before. Interestingly any time I had an issue it was with a Mac - it always mounts on a PC. I'll stop now before I open up a can of worms.
Best advice I have is get a Dropbox account. You can use that guy to move files from a computer to the SD card without having to mount to the computer. Perhaps you can get a factory ROM (with root of course) on your phone that way?

You can get a app from the market called SWIFTP (free) & connect to your sdcard via ftp server. This can be a temporary fix till you get your connection error resolved.

I have 1 USB port on my laptop that the Epic shows up as "unknown device" on. Works on every other port, and everything else works just fine on the same port. The factory USB cable is finicky!

uable to get usb connection working

since around a week ago my phone has not been able to connect to the usb ,
it does still charge via usb cable from the pc but the cable is not detected for mass storage ,kies or usb debug .
i know drivers are ok on pc as my wifes phone still connects fine .
is there any way to test that the usb socket is broken internally

i am haing same prob here after flashing a rom

just backing phone up with clockwork mod then going to do a factory restore to see if it cures the problem ,dont think it will but i can but try . device doesnt even go into mtp ? mode .
even in clockwork recovery when the usb is mounted as mass storage it isnt detected
well tried that no success , cant send phone back as cant factory restore it as i cant connect to odin. by the way what rom are you running and what version of galaxy have you got 8gb or 16gb

Have you tried the debugging mode?
EDIT : Try installing the usb drivers from my signature.

ive tried debugging mode no different , i can even select - deselect usb debugging whist the usb cable is connected .
the usb drivers from your sig are for windows x64
my wifes galaxy s is detected by the computer fine ,same usb cable and port

windows 7 32 bit

Can't you get hold of a friend's usb cable?

hi i have multiple usb cables here 2 original samsung galaxy cables plus multiple other micro usb cables . non of which work with the phone . not to sound ignorant but dont you think i have tried the obvious things first ?

Try a wipe/reset
If that doesnt work, try an other rom .... Stock or non-darkyy
If that doesnt work, im afraid there is a hardware problem

DID you try to put a RIGHT cable into a WRONG hole???

You are not alone, I have exactly the same problem, but wrote it off as a hardware problem, because it started after my son (9 months and teething) gnawed on the phone for some time...

ok tried different roms etc no luck must be hardware related going to open the phone tomorrow and check the usb socket . only really worried incase i need to use odin to recover after a bad flash , or incase the usb decides to die completely and i cant charge the phone

Hey Jona29 i had the same problem some time ago i solved it by changing usb port (preferably one direct to motherboard) while pc is off then start it while in download mode and flash with odin.
Good luck bud, i know how frustrating it is

UPDATE ! fixed the phone ,yes it was hardware not software at fault . dissasembled the phone and removed the board with the usb connector on .
heated the board around the connector with a pyro pen to reflow the solder
let it cooled and then reassembled the phone .
powered up phone and connected usb lead ,computer recognised phone and phone recognised usb connection
probably took me 30 mins to complete the task.
better than say a 4 week wait from samsung

Slick. I have taken my phone apart for USB problems as well, but I would be scared to try to reflow something on the PBC. The connections are so small.
I have had the USB issue as well but it always seemed to be the cooked ROM iI was using.
Ian

I had the same problem, after using DXJPA ... every time i connected the phone (even in boot mode) i received "USB device not recognized" ... I don't know what worked in the end, but i tried a lot of things: I bought a new cable (same problem), I used another computer (same problem), I tried on W7 x64, W7 x32, XP SP3 (same problem), uninstalled and reinstalled Kies, I uninstalled and reinstalled an older version of Kies, changed the phone form a computer to another, played a lot with USB ports ...
After 2-3 hours of pain, Odin saw the phone ... flash it to JPY and no USB problem anymore ...
Maybe this will help someone

[Q] Windows will not recognize Note 3 anymore, help please!

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks

Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?

Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.

Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?

Thank you! Worked perfectly!

I have the same problem, do you have any solutions ? Thanks.

I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!

please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...

I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!

[Q] s5 wont connect to computer

Hi all,
I had just got my s5 back from a screen repair by samsung two days ago and when i connected my phone to my computer (with the usb 3.0 cable the phone came with), the computer installed all the drivers and what not but my s5 wouldnt say "USB installer connected"(or something along the lines of that like it usually did). The computer wont show my phone either. This makes it virtually impossible to transfer files between my phone and computer. Ive tried uninstalling and reinstalling drivers and ive also tried using samsing kies but it tells me that my s5 isnt compatible (even though it should be). Ive tried using a different usb cable and the same thing happens. What should i do?

Can't Connect to any PCs

I've had my S4 for just about two years now, and have been looking into getting a new phone. I wanted to update it to 5.0 and back it up. My charging port went (yet again) so I bought a replacement and now it will charge like new. However, I cannot get it to connect to any PC and it won't show up in devices.
Things I have tried to remedy this:
-Unistalled/reinstalled newest drivers
-Uninstalled/reinstalled newest Kies
-Four different cables (all of which claim to be OEM, one IS OEM)
-Multiple USB ports on two PCs (Win 7, Win 10) and an iMac
-Checked all connections of new charging port
-Changed USB settings to MTP, MTP+ADB
As I said, I have run out of options. I can only get this thing to charge when connected to a computer, no data. It won't even show up under Device Manager or as a USB storage device.

that didn't work either. The charging port is brand new, and also a brand new cable. Any other suggestions?

Try flashing your device with the default rom

how would I do that? I can't connect it to PC to back it up or download a ROM
