Hi.
Have Boostmobile Epic that came unrooted.
Downloaded drivers and phone shows in device manager under com ports.
Tried 11 USB cables then saw a video from qbking and bought a blackberry to use its cable making it 12 cables, none work.
Tried 2 computers with Vista and Win 7 x64.
Epic won't communicate with either comp with debugging on or off.
As i said in topic, one click root won't work. Says Phone is not connected.
I also cannot sideload content onto SD card because it does not show in My Computer.
It has been flashed to boost so i assume it has communicated with a PC in the past.
What can i do to fix this?
Reboot pc and phone then try again. If that doesn't work then uninstall drivers from pc then install again. Reboot pc after install after reboot plug in epic then wait for it to finish installing drivers then reboot both again then use odin.
You can also connect the phone with usb debugging on, then go into device manager on the computer and look for "other" or samsung android in USB section. Click on that and select update drivers and let windows update search and install drivers...it takes awhile.
just did the uninstall drivers then reboot both thing.
Driver installation shows device ready to use as...
SAMSUNG USB Composite Device
SAMSUNG Mobile Modem #2
SAMSUNG Mobile Modem Diagnostic Serial Port (WDM) (COM5)
All ready to use.
But Still not showing in my computer for file transfer or working in usb debugging mode for root.

Try the update driver choice in device manager. The CDC driver is missing. I think it loads 5 drivers if I remember correctly with USB on...yeah the mass storage driver is missing too. Let Windows update find them all.

Hi, thanks for help.
Just tried uninstalling everything and letting windows find drivers. Windows found a different driver package from S3 studio or something but I still get no mass storage or root.
I've read you can root and install roms without a computer Guess that will have to be my route.
As far as mass storage goes... It's annoying but I pulled the back off and put SD card directly into computer
You are sliding down the pulldown on your epic screen and pushing mount sd card for mass storage right?

Yeah, the robot pic turns from green to orange but it never actually connects to either computer.
Going to my brothers house soon to check his 2 computers, he says his Thunderbolt will only work on one.

Some computers are finicky and will only work on the USB port used to install the drivers. Odin only works on the left side of my laptop and mass storage works on the right...go figure!
The fact that the phone thinks it connects and the computer probably makes the connection noise shows there is still a driver problem. Did you reboot the computer and phone after the full driver installation?
Yes I restarted both several times while installing/uninstalling
Drivers... I have just accepted that I need to remove the card to sideload content.
On a side note, I am now afraid to root my phone and change the roms because I'm on boostmobile and will be unable to connect phone to a computer to fix if something goes wrong.

after you install drivers, reboot, then plug in your phone w debugging on, it should install a bunch of drivers, then take forever on modem, unplug and replug the usb from the phone really fast, this should trip it up into moving to the next device... there should be at least two or three more. If you have GB loaded for some reason the RNDIS drivers are wonky. Make sure you use a USB port on your motherboard, not on a PCI, not on a front port... the drivers are acting weird lately, like they changed em up a bit... idunno... but once you get a setup, dont mess with it! Hope somethin helps... Its almost guaranteed the drivers, unless the Boost is the issue, idunno...
ive had that same problem ever sense ive got the phone, what if you havent given up there is another way for you to connect to your computer. It is very simple and fast it is how i connect now and it works every time.
1. Have computer on and Phone off
2. Boot your phone into ClockworkMod 3.1.0.1 (Power/camera/volume down)(it must be this version of clockwork)
3. Go to mounts and storage
4. On the bottom of the menu you must click mount usb storage.
5. Plug your phone into the computer and your computer should recognize your phone now.
Also if your on Vista / Win7 you should run the command line (cmd) or the bat file to root with admin rights: Right click cmd or the run.bat and select run as administrator and that hould help.

good to know.
I'm having problems getting my phone recognized by Heimdall (both Windows and Mac) and Odin (Windows). Here's the situation.
I have a practically fresh install of Windows with no drivers installed. I downloaded Heimdall to try and restore my Epic that has the [Phone] ! [PC] screen. I booted it into recovery mode, ran zadig, used a non-Samsung cable, etc. Heimdall's detect button recognizes my phone. However, when I actually try and do anything, I get "Error: libusb error: -12". I've seen some posts from different forums that say this is correlated with NOT having the zadig drivers installed, so I reinstalled them and rebooted for good measure. I still have the same problem.
So, I assumed that Heimdall was a lost cause and moved on to Odin. I'm following the how to in the dev forum and I installed the drivers mentioned there (x64 as I'm on Win 7 64 bit), downloaded the TAR, and so on. I open up Odin, put my phone in download mode, plug it in... and Windows says that it's an unknown device and can't recognize it. I've uninstalled/reinstalled the drivers several times, swapped out USB cables, and I can't find or think of anything more to do.
Help!
Okay when you open device manager and find the "unknown device" update the driver with your epic 4g drivers this will fix it hopefully... if not try and unistalling it pulling your usb out and popping out the battery and leave it out and plug in the usb and go into dlmode and it should reset things.

I'm getting a screen that says "The best software for your device is already installed. Windows has determined the driver software for your device is already up to date." and the dialog still shows Unknown Device.

Hmm that's weird sorry.... don't have a 64bit pc so I've never tried em.... I'm at a loss then... usually if you unistall it and go back into download mode it erases the previous setup and asks you for the reccommended install or advance install which is what you would want to advance install the correct drivers...

Well thanks for trying. I'm basically where I started, unfortunately: I put the phone in download mode, it tells me it's an Unknown Device, I can't update/advanced install the correct drivers, and Odin doesn't recognize my device.

Just read someone fixed this by reinstalling Windows 7. Otherwise try Heimdall. It installs it's own drivers. Check out post 2 here:

this is a direct link to the drivers needed.
Well, I got it to work with Heimdall. It seems to have been a combination of the USB cable, USB port, and drivers that caused my problems. Here's how I got it to work for those who might have this problem in the future.
1. Uninstall literally everything related to Samsung, Heimdall, Odin, etc. This means uninstall any drivers, delete all instances of Odin, Heimdall, Kies, or any other software.
2. Reboot.
3. Download the latest version of Heimdall (1.3.1).
4. Remove the battery from your Epic and let it sit for about 15 minutes.
5. Get a fresh, non-Samsung (and possibly non Amazon, as that's another one that didn't work for me) USB cable. I opened a brand new Monoprice one that I had laying around.
6. Plug in the cable to a USB port directly on your computer.
7. Hold down power and 1 while plugging in the USB cable (this is with the battery still out).
8. Run zadig.exe, which comes with Heimdall. The computer should recognize it as a Samsung composite device or "Gadget serial". Install drivers.
9. Open Heimdall and flash. DON'T TOUCH ANYTHING UNTIL IT'S DONE!
Great. As long as u got it to work. Excellent.

My computer won't detect my Epic 4g when it's powered up, with either Debugging enabled or disabled. BUT, it does detect it when the phone is in Download Mode.
I have tried several different cables on all my usb ports. And the cable and port that I am currently connected with works perfectly on my other Epic 4g...
I wanted to root this Epic, but couldn't get computer to recognize it. When I plug it in when phone is powered up, I get no notification in the sys tray, nothing new shows up in device manager, no new drives show in My Computer, Odin doesn't recognize any devices.
So I put phone into DL Mode, plugged it in, and the computer recognized it, installed drivers, and Odin installed both Kernal-GB-3a and ACSRecovery1.0.0.5 successfully!
But when I boot the phone back up in order to copy the Superuser zip file onto SD card, same problem as before... Whether I click "Connect storage to PC" on phone or not, computer doesn't acknowledge.
Any advice?
(phone was on stock EL30 prior, fyi)

when you allow windows to automatically install the drivers, it doesn't always install the drivers properly. but when you manually install them, the installation process assures that they are ALL installed properly.

what you want to do is dial ##8778# and switch the bottom one to pda and the top to modem thats the problem trust me i tried installing the drivers and reinstalling it dont work... do this and its a gaurentee to work
So I have done something to my epic, I don't know if it would count as bricked soft bricked or whatever but when I turn it on it bootloops on samsung logo but I can still enter download mode, So I figured I would flash a stock rom with odin and start over.
I went to this thread
http://forum.xda-developers.com/showthread.php?t=1052813
downloaded necessary drivers
installed and tried to connect to odin
I've tried every combination of powering the phone with the computer, then putting in download mode
I've tried powering on with battery booting into download mode opening odin selecting pit and tar and then pluging it in and nothing.
when the pc does recognize the phone it says device not recognized or device malfunctioned.
I saw a post somewhere with someone saying I needed to "advanced install" the drivers. So whatever that means I tried to uninstall the device from device manager while plugged in in download mode and updating the driver to the 64bit samsung usb driver and it says "unknown device already has best driver installed"
the computer I'm using is an HP DM1-4010us not that I think it would matter.
If anyone has anymore suggestions, or can suggest a method or pattern of step by step what I need to do
maybe install the drivers in a different compatibility mode?
what about odin compatibility?
System UAC is turned off and firewall is off too just in case it may be blocking odin from communicating with comm ports so I know that can't be the issue.
Thanks for listening to my overly detailed and confused ramblings and thanks in advance for any advice or help offered.

Try a different USB port and cable the stock cable sucks azz try a blackberry cable.
Have you tried a different usb port?
I have always used the cable that came with my epic, are you using it?
I'd at least open odin, put your phone into download mode and then connect it to the PC and see if with the stock cable it is recognized. That will tell you perhaps the cable you're using isn't connecting right for odin's use.
do you have any other cell phone drivers on your PC? I've seen where they conflict. Remove all cells phone drivers, reboot, install the epic drivers for win7 64bit

Make sure you downloaded the drivers named "Samsung_Mobile_Drivers_V1.3.8.." if not then that's the problem, if you need it I can email you the the file. Try all the usb cables in your house and all the computers as well, and take out sd card, I've also had this odin problem and I'm also sure it's your drivers since there are like 10 samsung drivers floating around lol.

Looks like you tried different USB cables (hopefully NEW ones), and different ports too. Along with Kies.
Try going into device manager (check show hidden devices too!) and uninstall ANY Samsung drivers or software you have installed. And reboot.
Download and install the latest drivers for the Epic 4GT [ http://org.downloadcenter.samsung.c...342248/Sprint_d710_USB_Driver_v1_3_2360_0.exe ]
Reboot your system. Then try to connect again.
If you have some type of Antivirus/Antispyware application you may also want to try and temporarily disable it too. I've seen this happen before.

I'm pretty sure it is not my antivirus because the other computer has the exact same antivirus. Also, in Device Manager, I enabled hidden devices and I do not see any drivers that seem like they have to do with Samsung.

Wow not sure what else to try. If you've tried removing all drivers and re-installing them, using brand new USB cable(s), using different USB ports and disabling AV software and if it does connect and show up on other PCs yet it still wont show on one PC, then something is amiss with that machine.
When you're connecting your device you do have it on too right? I'm sure you do but just checking.
Did you install any ROM on this device already? There are some international versions that if installed on this device disable the USB port.
And does it show up on other machines just not this one?
If it shows up on other machines than it there is something amok with that PC.
If it doesn't then..
One last thing you might want to attempt is to download sfhub's One-click FF18 http://forum.xda-developers.com/showthread.php?t=1721229 download the 'reset data' and extract the exe.
Make sure you phone is off and NOT attached to the PC.
Run the One-click application.
Simultaneously Press and Hold [Power] [VolDn] until confirmation screen appears
Press [VolUp] to enter Download mode
Then Attach your phone via USB to the PC and see if it shows up on a COM Port (anyone is OK).
IF it does you can then at least flash the stock rooted FF18 and get the device to probably work correctly next time you plug it in after of course the entire Odin/Update finishes and your phone restarts.
Just reaching here but hope that helps.

This shows up on other computers but not this one. I did install CM9 onto my phone, but when I was on stock, this problem was still happening. This is most likely something with this PC. Thanks for you help.
Well then that's it. PC is the issue it won't show. Something is pooped.
Good luck.
Just to be clear, when someone says, 'try different usb ports' make sure you only use the ports on the motherboard and not the ones on the front of the case or door.
It's the difference between powered and un powered.
That one the threw me for a loop on my win7 when I usually use my laptop with xp.
