Running rooted GB08 and want to upgrade to GB27. However, I can't get my computer to recognize my phone. When I plug the phone in to a usb port, it charges, but nothing happens in windows, nothing in device managers, notihng.
I've tried my desktop, notebook and multiple usb cables.
What's going on?
Sounds like you either have bent pins inside the port or the solder joints on the port are cracked. You can either fix it yourself, or have someone else do it. If it can't be read by a computer, going back to stock FL24 will be a bit difficult if you want to go to sprint and have them replace it.

Previously my USB port was working fine and mass storage was working correctly. Now I can't connect to my laptop and it says USB Device Not Recognized. I wiped out my laptop and it still doesn't work. I've looked around and nothing seems to solve my problem. I'm on SyndicateROM Frozen 1.0.2 and running Windows 7 32-bit. Can anyone solve my problem?
Are you using the stock samsung cable? If so ditch it for anything else. Their stock cable flakes out...

I'm using the stock cable. where would you recommend to get another one?
i have been dealing with this problem for about a week and a half. I never thought it was the USB. I borrowed my brothers blackberry usb cable and it worked like a charm. Thanks.

I have tons laying around from various other devices, any Micro USB should do. If you don't have any from other devices then any place like radio shack, office max/depot, staples, microcenter, bestbuy.... should carry them, probably even walmart and target in the electronics section. You are looking for a micro USB cable.
You don't need anything fancy(expensive) that's gold plated, high speed, etc... Just try to find something that looks a little less flimsy than the one Samsung gave us.
1. Buy this
2. Plug phone into PC
3. ?????
4. CEELLLEEEBRATE GOOD TIMES COME ON!
Just use a different cable. The cable that comes with the phone is a pos.... How i know?? My girlfriend almost threw the phone and the laptop over the window.. when she got tired of being trying she asked me and I just got the cable from my Evo and voila!!! Its working!!!
Also I had issues if it was a case USB and not one directly on the mobo.
I just used my sisters cable and now it works like a charm.
Today I tried to flash an alternate modem using Odin and didn't realize I was using a bad usb cable. It disconnected in the middle of the flash and now the PC stopped recognizing the device. I have two PC's that had no trouble recognizing the device and now neither one will recognize it. And now my phone shows the phone and PC pic with the exclamation triangle in the middle and it won't boot. I can't even get into CWM recovery. I tried searching for a fix with no luck. Please post a link for a fix if there is one. I'm still able to go into download mode so I'm hopeful that there is a fix. I'm just worried because both my PC's won't recognize the device. Any help will be appreciated. Thanks.

Yeah I have other cable's. I have a T-Mobile brand data cable that I bought at the tmobile store that has worked flawlessly along with another cable that I have laying around. It was just a terrible accident that I grabbed the faulty one. I thought that cable was thrown away because I asked my gf to trash it awhile back. It's trashed now lol. So yeah I tried using a good cable with no luck

I suggest you to buy the usb jig for epic on eBay.com
That should get your phone into download mode. Use bb cables, they are much better than the stock.

He said he can get into download mode.
OP uninstall the drivers and connect it to Odin in download mode to see if Windows starts loading drivers.

No need to uninstall the driver
I think the biggest misconception is reverting to uninstalling Epic 4G's drivers. That's only necessary when the installation was corrupt.
It will still improperly recognize it as unrecognized device if he allowed that popup on all his usb ports.
Plug your epic with the bad cable to each of your ports and purposely let it all get the unrecognized device message.
Now plug in your epic on each port, and on each of them do this:
Go to device manager, under usb root hubs category, go to the unrecognized device and uninstall it. Unplug the cable and proceed to the next port, repeat these steps for all of your ports. If a bad cable was the issue, this should resolve it.
NOW, with the epic in download mode, plug in to any port with your GOOD cable and it will work now. If you get the same issue, your ports could be dirty, dirt is your enemy here. If that's not the case, try a thicker, better cable. My epic works like magic with thick blackberry cables.
I wish you could sticky the fixes I've made to this issue Kenny, i find myself repeatedly solving the same issue time and time again lol.

I'll attempt this when I get out of work. Thanks for the replies guys. But why would this same issue be happening on both my PC's at the same time when they were both working perfectly fine a couple of days ago?

Got it!
Ok for some reason both of my computers decided that they wanted to recognize my epic. I was about to do what Shinydude100 suggested and right when i connected the usb, it was recognized and drivers started to install. I had already uninstalled the drivers when i first had the problem, but just on one PC. When i noticed that i had the same issue with my second PC i knew it probably wasnt the drivers. I dont understand what the issue was but i left it alone for about 24 hours and now both PCs recognize it. Thanks everyone for your help.

I've had nothing but bad luck with the cables that shipped with the epic.
What is nice is the cables that shipped with the palm Pre x and HP touchpad.... even now the touchpad USB and wall plug can be found very cheaply.... and the output on the charger is 2 A.... so it charges the epic quickly... even with the optional 4000mwh hump-back-of-notre-dame aftermarket battery.
Alright, so when plugging my phone into my new (literally bought today) netbook, nothing happens.
I installed the Samsung USB drivers as well as Kies. And when plugging the phone in afterwards, nothing happens. From my understanding, whenever plugging in a device into the PC, a bubble on the bottom right hand side would pop up saying "Installing device hardware" or something along those lines.
But for this netbook, nothing. Nothing pops up at all. It's like it doesn't even know a device is plugged in. Although, my phone does charge from the connection and that's about it.
I've used 4 different cables. Two generic cables, Energizer cable, and a RocketFish cable. I was successful with the Energizer cable when I used my friend's laptop to ODIN back to EL29 from the FH13 update.
I'm pretty much stumped right now. Not sure what's going on. Considering returning the laptop and exchanging it for another one.
Have you tried turning on USB debugging?
Sent from my SPH-D710 using xda app-developers app
Yes I have.
The netbook will recognize my flash drive though. But not the phone. :|
Welp, went back and returned for Asus laptop. The thing recognized everything. I guess the netbook wasn't meant to be.

Go into your dialer and type ##8778# switch to cp and youll see that your device will start downloading the drivers then you should be in business sorry if I put cp wrong long day but I think thats it there should be 3 settings there the one your on cp and all I think so once your done make sure you go back in and change back afterwards or your sd card wont read right. Hope this helps if so say thanks
There is a known issue where the USB port "breaks" somehow. I just experienced this, so it may be your issue also.
Troubleshoot:
drivers
different cords
different devices
Which you have done so it's most likely your phones USB port
So I have an I747 running stock 4.1.2 that was given to me by a friend. When I received it, I noticed I could not access it from any computer. I asked her if she had any trouble and she said no, that she always connected it to a computer and it was easily picked up. Before she gave me the phone, she factory wiped it. Since then, no computer can see it and no option appears in the drag-down menu. Using *#7284#, I set it to MTP and MTP+ADB with nothing changing. I have tried battery pulls, uninstalling/reinstalling drivers, Kies, etc., even changing cables (from cheap ones to the OEM Samsung and HTC ones). I've tried it on Ubuntu 12.10, 11.04, Windows 8, Windows 7, XP, and even Mountain Lion. No computers can see it.
Anyone have any ideas? I cannot even try to root or anything because no version of ODIN works. Yet, if I connect my S2 Skyrocket, all PCs read it, regardless of cable or OS.
I had this problem before and could not find a proper reason.
There *COULD* be a problem with your phones USB connecter. Some hardware could be damaged. This can be caused by incorrectly unplugging or plugging the device in, which can jostle the hardware and break it.
How long was the phone used for?
I hope you have a warranty :/.
Unfortunately, no, the phone does not have warranty. If the USB port were damaged, would it still charge fine? Because apart from no connectivity to a computer, the phone works fine and can see an SD card in it. Its internal storage is accessible through file managers, as well.
If it is damaged, would I be able to see the damage when opening it up? I would not hesitate to fix it if it is something I can re-solder back on or replace. I just do not want to get a replacement USB port if it is not the problem.
I had a very similar problem with my i747. If your phone charges when it's plugged in to the USB port of the computer, you might try this:
Make sure the Samsung drivers are installed. Power off your phone. Power on the phone in Download mode. (Volume Down + Home + Power) Press Volume Up to continue. Once it's in Download mode, plug it into your computer. Windows should now discover it and load the driver. Once this is complete, unplug the phone from the computer, and pull the battery out of the phone to get out of Download mode. Replace the battery, and power on the phone like normal. It should connect to the computer properly.
I found this on the Verizon S3 forums over on Android Central. Worked for me after a lot of other things didn't.
Best of luck!

I have never been "in" the USB port area when taking apart my i747, I would assume it would be visible...but you should try the suggestion of USB drivers from the poster above

In some cases, yes. Charging operation only needs the positive and negative 5 volt pins on the usb bus. In order to transfer data ( and be recognized by the host OS) you must also have connection across the two data pins. It is possible that one of the data pins on the phone's connector OR either end of the micro usb is bent, broken, or otherwise not making connection. Also i have about a hundred (more like 10 but you get the point) micro usb cables laying around and some will ONLY charge. I can't give you a scientific explanation why other than the phone just doesn't like some of them so trying a different micro usb could be the key.

Like you said, I think that sometimes a phone not liking a cable is the truth. What sucks is I never had this problem with my s2 skyrocket on any cable. I may have to send it in for repair if anything. I upgraded to 4.3 last night and still the same so I feel it's definitely a hardware problem.

Thanks for all the suggestions, guys.
hey i have a sgs3 my usb port is not syncing is their a way that i can sync threw the motherboard like attaching wires plz help
You can order a replacement part if you feel youre up to the task of replacing it. I wouldnt try to wire up the motherboard out of fear that id do even more damage. There are apps that will allow you to connect/sync with your computer wirelessly.
