[Q] usb connection problem in downloading mode

helllo every body
i have a problem.i was updating my galaxy s through samsung kies..it got stucked after 30%..i disconnected it n then tried to update through odin multiloader..again it got stuck.i tried twice n it got stuck..now the phone goes to download mode..but cant be detected by computer..can any body help me plz

do you have another PC?
it's your windows + PC problem
best way is on WinXP 32bit on a good PC with working USB ports
some PC have buggy USB ports
unplug everything else from the USB ports except for mouse and keyboard (in case they are USB mouse/keyb)

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

What OS are you running?

windows 7 32 bit
galaxy s 16gb with darkys v8 gingerbread (previously darkys version 6)

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] unroot??

is it possibile to unroot the epic eb13 without having to use the cable/ odin / or anything computer related?
my phone is not working with odin or anything if i plug the usb in, but i am able to move stuff to and from my SD card by just putting the SD card in the computer.
took to sprint to try and get it repaired BUT cause they saw i was rooted they said they cant help me because i am rooted.
by the way i have tried VARIOUS methods of trying to get the usb to work by using 4 different usb cables. uninstall and install the drivers. different usb slots in the computer.
all keep showing
"USB device not recognized"

I had this problem when I was getting ready to upgrade from rooted DK18 to EB13. I wanted to backup my stuff first but the usb wouldn't recognize mass storage. I think I may have broke something when I started removing apk's and disabled touchwiz in favor of launcher pro. The phone worked fine but mass storage was not available. When I installed the Epic drivers on my laptop and connected my phone, the mass storage still wasn't recognized but Odin did see a connection.
If Odin still sees your connection on a different pc (disregard the windows error), then flash whatever firmware you need and all should be well.
Let me know if this helps.
PS....Don't forget to disconnect and reconnect your phone at least twice after installing drivers on a new pc. It takes at least 2 reconnects to install the drivers correctly...at least thats always been my experience.

im getting nothing in odin =/

Yes, but have you tried connecting to a different pc. I had the exact same issue on my desktop pc and then I tried on my laptop. For some unknown reason Odin worked fine (but still no mass storage).
At first I thought there was something wrong with my desktop's usb ports but after I flashed back to stock, suddenly mass storage was available on both my laptop and the original pc. Don't ask me why, it just worked.

Doesn't doing a hard reset make you lose ur root?

s4 and PC connection

hello! i was searching through the internet and I can't seem to find a definite answer for this type of problem.
my galaxy s4 can't seem to have a stable connection with my PC. it works
so far what I've done
-plugged it directly to the motherboard usb port
-used samsung original cable
-install all USB drivers (installer, kies)
-uninstall, reinstalled drivers but no avail
-used different cables. ( the original cable doesnt seem to work. whenever i plug my device, it only charges. but there is no notificcation that tells me the phone and PC are connected to something) and then i used a motorola cable and the phone and PC seem to detect each other. but only in one of the motherboard ports.
and also, if ever the PC detects my phone, the "connect/disconnect" loop appears... the "connect/disconnect" loop DISAPPEARS when i plugged the phone to a specific port. BUT, it cant seem to have a stable connection. whenever i transfer a large file, lets say a movie. it copies the file half way then the phone suddenly disconnects then reconnects by itself automatically like nothing happened. I couldn't also flash firmwares cuz whenever odin tries to push the files into my phone, suddenly odin will stop and says "disconnected"..... by the way, my PC's usb ports are OK. it can detect and transfer large files from my brother's optimus G and my sister's motorola droid with no problem. I have used this PC for flashing my previous phones with no problem (SGS2, SGS3, SGS1, Gnex, NOTE2, SGmini, china tablets). Yes i do change phone frequently.
can someone please enlighten me on this..and oh! by the way, I tried flashing and transferring files from my gf's laptop and there seem to be no problem at all... I even used the original samsung cable which doesn't work on my PC at home. I would really like to flash my s4 with the latest 4.3 jellybean, and my gf is back in her home town for the sem break so I can't use her laptop for now cuz she has brought it with her..
I would really any comments and insights will be highly appreciated. thank you!

Your phone has a defective usb port, replace it if it has warranty

not really. because it works with my gf's laptop no problem. but thanks for your reply.,

please help

The hint's in your 2nd last post. There's obviously something PC-side going on; your PC - probably with the USB ports, if it works on your GF's PC. Think about it, that's logic. If it was phone-side, it wouldn't work with any PC.

Fix
First connect ur phone to the pc whit the original white cable
them in ur S4 prees the notification of the usb is connected
Enjoy
If u just connect the phone it will only charge. U have to touch the notification.
