I have USB mode set to Kies, and debugging is off. I plug it in to the computer and start up Kies, but nothing happens. My player charges and even the Kies screen with the picture of the USB cable comes up. Kies still just looks like nothing was plugged in. It worked for like the past 4 months, but last week it started doing this for some reason. Any ideas?
Try the 'troubleshoot problems' option. (Click on the connecting phone icon in Kies). Follow the steps and it should work. Otherwise try other usb ports. Or the ports in the back of your pc if needed.

Well I had tried the troubleshoot thing several times before with no luck. I had never thought to try another USB port until you mentioned it. I tried a different one and it worked! it looks like I have a bum port on my windows build. well that just sucks

Hey, I was just wondering if it's possible that the stock charging cable is able to charge my phone, but has malfunctioned somehow to not let it be recognized by my computer?
Basically I've been trying to get my computer to recognize my phone for a week now.
I'm no expert with this stuff but I'm certainly not a noob. I've been rooted and have been flashing ROMs for months now and have odin'd many times before. Just one day none of my USB drives would work. I formatted my computer, reinstalled my drivers and i know the USB ports are functioning because they recognize other devices.
But when i plug my phone in i get "unknown device" where it used to recognize it once i had the samsung drivers installed. I've tested on a brand new computer, with samsung mobile drivers installed and same result, "unknown device"
Is Heimdall a viable option at this point? I've never tried that program but I have nothing to lose i guess, but someone can save me some precious time if they know it's not going to work, please let me know
P.S. this isn't an issue of not having debugging on or my computer seeing it as a cd-rom, the computer won't recognize the device with samsung drivers installed.
Have you not tried another cable?

unfortunately, i don't have any other microUSB - usb cable to test out. I was just going to buy a new charger since the Verizon store is down the street from me, but I figured I'd ask since I won't be able to go until tomorrow morning
From DroidXcon at AC:
"uninstall the drivers, reboot your computer, reinstall drivers, pull out the battery of your phone connect it, put your phone into download mode and let the composite drivers install...then unplug pop your battery back in , turn on the phone, throw it in debugging mode. and connect and see if it configures"
Thanks Kevin, I've actually been tracking that thread since yesterday and the issue for me is that the composite drivers won't install on its own which is really strange to me as i've not had this problem in the past. I also tried doing everything from scratch on a new computer and got the same results... anyway, i didn't get around to it but will try heimdall tonight and see if anything changes

Thanks for the suggestion. I got it figured out. Turned out to be my charging cable. It charges my phone but won't let my pc recognize it as a device. I tested it out with a coworker's captivate charger and it worked
Some micro USB cables are manufactured only to charge. The rocketfish brand cables from Best Buy, for example. It seems to me the manufactures simply leave out a connecter on one or both ends of the cable, or leave out one of the lines all together. Try another cable.
I just saw your using a stock cable... I'll post anyway in case this helps someone else. Good luck!
when i plug my phone into my computer, nothing. the phone pops up the notification to allow mass storage, but when i enable it the computer never shows the phone. i've messed back and forth with usb debugging, still nothing. is this sometihgn stupid i'm doing or what? I've even flashed a couple roms andstill nothing. help please?
its most likely the usb cable try a differnt one
that's what i thought, i tried two different cables (all i have are 2) and neither will work. Note, that when i use these two cables with the wall jack to charge they work.
do you have another computer? try it with another computer
or try a different usb port! or try installing mini kies that sometimes fixes the problems
Try rebooting and turning usb debugging off. Then plug up to pc (see if it installs drivers) then unplug, turn usb debugging back on and then plug up again. Should work after that.
OP-
A few days ago I posted regarding my similar issue (2-3 pages back).
I have still not resolved my problem, but that thread may give you an idea about troubleshooting.
Let me know if you figure it out.
For me, its most likely a phone issue & not a cpu problem.
I'm going to try cleaning my port with isopropyl alcohol later this afternoon.
You also might want to look at Callip's advice in the "PLEASE HELP" thread on this page.
wow, thanks for all the responses guys, i'll get to all this tomorrow some time and i will post my results.
First, i apologize if there is already a thread regarding this, but everything ive came across searching on google/xda has come to no avail.
i just got the i777, plugged it into my computer and nothing happens. on my phone it says "mtd connected" and charges.
ive turned on usb debugging, installed samsung kies, installed the drivers, tried the "dial *#7248#(or whatever it is), ive tried 3 different usb cables, all the usb ports on my laptop (brand new alienware), and also 2 other laptops. nothing works
my computer also makes the sound that its been connected. if i go into device manager it shows as Other devices > 7 CDC's with the yellow exclamation mark
if someone .could PLEASE help me it would be much obliged, all i want to do is start flashing again

Probably a bad usb connector on your phone. What rom are you currently on?
I was fearing this. Its all stock, not even rooted.
IF i have to get a new usb port, do i have to do any soldering?
When I had this problem I downloaded multiple different drivers and eventually found ones that worked . Try Google searching i777 usb drivers. I downloaded ones that worked from softpedia actually.

No soldering required. It's just a ribbon cable that connects to the main chip. Took me about an hour from start to finish, but i was being really careful.

He has said his computer recognizes the device, albeit it sees it as an unknown device. And it makes a sound when plugging it in. This tells me it's not a usb port problem but a driver problem. I have had this same problem. As I stated above. Even after installing kies it still didn't recognize it. I had to install the android sdk package, open the program and update, and then it still wouldn't recognize it. I had to download separate usb drivers for the phone as well. Who knows why, some computers or operating systems just have a harder time with the drivers. That's the problem in my opinion. Here's hoping it's not a usb port problem. Also this would prevent charging if it were a faulty usb port on the phone wouldn't it?

I wonder if the OP tried this on a computer with Windows XP. I've noticed Vista and 7 seem to have a hard time discovering/installing some usb devices. As for it not charging also..I think the pins inside the port are used separately for charging and connecting to pc.
My computer recognized my phone fine back when it was the Captivate, but it has a really hard time with my GS2. It often will say "invalid hardware id" or not show up at all. Usually it's fixed by swapping ports.
Hi,
When I plug my S4 into the USB port on my laptop it doesn't try to install drivers or anything. The phone starts to charge and that's it. I have USB Debuggin checked. I have tried this on 3 different Windows 7 PCs. I have latest drivers installed but that doesn't even matter because it never get to where it asks for drivers. I've looked all over for USB options and there isn't any.Anyone else ever have this problem?
Any help appreciated.
Are you rooted and running a rom other than stock?

Bone stock
Is this the stock cable? Have you tried another USB port?
I tried 2 different cables and 2 different laptops. Neither acknowledge I have a device plugged in.
I just another cable and this time on my desktop and still doesnt acknowledge anything is plugged in.
Wonder if an app you downloaded it causing it not to reconize it properly. Can you list what apps you have installed?

I'm going to wipe and reset the phone and try it again..stay tuned!
ok I wiped and reset my phone. All I did was unlock dev options. Check USB debugging and unknown sources under security and again my PC doesnt acknowledge it at all. It just goes into changing mode. I'm stumped
Edit: I'm going to wipe again and this time plug it in before I unlock dev options..
Edit2: wiped again, plugged in to PC and same thing....nothing..
Bump for help!
Are you using the supplied Samsung cable? I have at least 10 generic "micro usb to usb" cables at home that only allow charging. And only 2 or 3 that actually allow data transfer and make my computer see the phone. Seems like the one that came with the phone, and 2 of my motorola branded cables work, but none of the other many cable do anything other than charge the phone. Other than that, i'm stumped. I'd take it back if all else fails.

Did you even try to search? Plug your first sentence into the search all forums bar and see what comes up. There are so many threads on here about that problem. Give the search bar a try before creating a thread. That is on of the rules here.

Yes I did, I searched for a couple hours looking through threads even went to different websites. None of the solutions worked so I created a thread hoping someone could give me an answer as to what is going on with my phone
By your PC not charging your phone it is very hard to tell. Lets start with the basics. You have tried different usb ports on the computer. You have turned on USB debugging on your phone. You have tried different USB cables. You have uninstalled and re-installed kies on you computer. You have done what you could to clean the usb port on your phone. You have tried to connect your phone to the pc in download mode. That about exhausts my limited knowledge. Sounds like you have been pretty busy over the past couple of hours to get all that done. I am not sure what to tell you besides it sounds to me like your phones usb port is toast. Maybe you can do some searching and see if you can find some one that can repair that bad boy for you.
