[SOLVED] Phone Not Recognized by Computer

Hello everyone. My E4GT is unable to connect my computer after I install the drivers. I tried reinstalling them, used different usb ports, and different cables to find out that it still wouldn't work. The weird think is when I connect my phone to another computer after installing the drivers, it works. I'm hoping that someone knows of a fix to this.
OS: Windows XP SP3 32-bit
Edit: I solved this problem. What the problem was that I was missing usb.inf in WINDOWS/INF . To get this file, I got it from the other computer. At the time of me doing this, my only goal was to fix my webcam because I was getting an error about a missing .inf file.

Try downloading the kies , sp?, program for your PC, it installs Samsung drivers and may solve the issue

SP3 means Service Pack 3.
Kies did not solve my issue. Thanks for your help so far.

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.

Cool, but did you uninstall, reboot and then reinstall? And did you also disable the AV just in case?

Uninstalling Kies right now. I will post after I reboot my computer.

I rebooted my computer, installed the drivers, and it still did not work. It's like my computer does not know how to use the drivers for my phone.

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.

MTP device failed

I can't get my computer to recognize my phone and am starting to believe the phone itself is the problem. I've tried un-installing/re-installing drivers, everything on w7 is up to date, also tried a vista computer, and an xp computer. I've tried 8 different usb cables and all usb ports on 3 computers. Samsungs live chat was of no help. I tried 2 factory data resets on the phone which is a pain. Kies didn't work either. I've been trying to root my phone for weeks now but can't get past the first and easiest step. Any help would be greatly appreciated, thanks

you mentioned that you used 8 different usb cables, one of them was the original usb cable that came with the phone, right?

Have you tried using Android Commander? I find it more reliable than using windows to transfer files between phone and computer.

Windows doesn't "see" note 2.

Good Evening folks,
I'm posting here after spending the better part of 2 days trying to figure out why this doesn't work.
So, i have the following:
model: GT-N7100
Version: 4.1.1
Build: JRo03C - ALJ1
I run a PC with windows 7 and also have a laptop with windows 8.
Now, initially i only wanted to root my device to install an addblocker on it and get rid of some bloatware. so i went and got samsung note2 toolkit here on XDA. (also tried others)
but no matter how i tried the pc (nor laptop) would see the note 2. it would plug in, it would charge... but windows ignored it otherwise.
i have tried al 8 of my USB ports on the desktop, and all 3 on the laptop. none of them work
3 different USB cables.
re-booted more then times then i can count.
i have manually installed the samsung drivers.
i have tried installing the windows MTP Porting kit
all to no avail.
So before i can even START to root... i need it to to play nice with my machines... anyone have ANY suggestions on what the hell is going on here.

Did you install Kies on your PC? That program needs to be open when you connect your phone and then it will install the needed drivers.

My Note 2 N7100 is 'seen' by my windows 8 machine, but it doesnt seem to copy/ paste anything. Pops up with an error. The same happens on a Mac Lion machine. Installed the Android File Transfer app, but the moment I connect my phone, it pops up a message saying please restart your device so that it can be detected. I am tired of transferring individual files over AirDroid Any help?

What's the error message?

Happened to me before, un install kies on your pc reboot, download from Samsung website and install again, should work
Sent from my GT-N7100 using xda app-developers app

first of all I forgot to mention that this should've been posted in Q&A section
for the problem try the following steps. after each one of them try connecting again. keep net disconnected while you follow the steps.
if it starts working then stop other wise continue.
1)use a diff comp, but you already did that , use a different cable, you didn't mention it
2)try uninstalling drivers via programs and features.
3)try installing drivers - preferably via mskip's toolkit
if you have windows 7, then directly install it
if you have windows 8, then first disable driver signature enforcement via this guide's last question.
4)try re installing windows. if you don't wanna do that then
open device manager
in view -> show hidden devices
delete each one that says samsung, note ii or note 2, android, google, adb, gt-n7100, n7100
this will ensure that you truly remove drivers
follow step 3) after this.
Hope I helped

All the usual and helpful ideas have been listed and you should definitely work thru those to make sure you are not missing something obvious but critical. I also use Win8 (64) and all was well with my Note2 showing up as an MTP device and wll working then one day, seemingly spontaneously, it suddenly didnt! When I would plug my Note2 in, Windows would give me a USB error telling me it could nto recognise the device! To cut a long story short, I tried my wife's S2 and IT appered fine as an MTP device happily enough, so that ruled out the cable, the port and the computer/OS.
I then tried my Note2 on my laptop, and once again it came up as USB error, so the problem was following the DEVICE around....
After a lot of googling, I tried on thing that fixed it instantly:
On the phone, go into Settings, Security and delete all the "Device Administrators" which in my case was just my Email app. That did delete my email account from my phone (contacts, email etc) but didnt matter as phone is just a dumb client to the mail server so no loss of any real data.
Once removed, I then plugged phone in and BOOM! MTP device happily appeared! I then went back in and just re-added my email account and re-activated Device Administrator when asked. Working ever since.
Not saying this is your problem, but it was an eye opener to me that the Device Administrator could 'lock out' the USB connection of the device....
Hope this helps.

I would also recommend checking your Windows Update log - especially if you have it set to automatic updates. After I installed the drivers off of the Samsung website, Windows Update tried to "Update" my drivers to an older version (I do manual Windows Updates). The first time it asked, I let it, and my phone couldn't connect anymore. Once I stopped that silliness I stopped having problems.

I was having the same problem, but I was using a USB cord that I had from my old phone. Switched to the white one that came with my Note 2 and it started working.

[Q] Galaxy Ace II cannot be detected by PC (XP/W7/W8)

Hello, I'm the new guy, kind of (I'm new to this forum but somewhat a technological handyman, so to speak).
I had recently obtained a Samsung Galaxy Ace II, everything was going good on the phone, hell, it's what? Two years old now? Anyway, I noticed the immense trouble I've been having trying to get several Windows PCs/laptops to detect anything from the phone, no driver updates, installations, not even from the trustworthy SAMSUNG Kies application. It is becoming a real problem as I really want to keep this phone, root it, installing several ROMs as I go along, but no, the computers won't even allow me to access the contents of my SD card through USB.
(Note: I have manually downloaded and installed SAMSUNG USB drivers and pooft, still nothing!)
I have tried quite a few methods to allow the PCs to establish a connection with the phone e.g. Dialing "*#7284#*, accessing "PhoneUtil", choosing "PDA" as the good mode, even switching to "MODEM" then back to "PDA"; Uninstalling/Reinstalling drivers; Attempting Kies.
I guess I am on the look out for a new-ish phone to replace this, which saddens me as I love being able to root, install various ROMs, Kernels etc, personally I like this phone too, more than my Spica running ICS (couldn't be too hard though, it wasn't stable whatsoever).
If anyone on this board could find a solution to this problem for me, I would be ever so grateful, I don't doubt it though, I love the work of XDA. Thank you.

Turn off the phone with no cable attached, press volume down, home and power at the same time and then volume up to put it in ODIN mode and connect it to the PC (use windows vista or newer so it auto installs the driver) It should install something like Samsung USB serial device. Tell if it works

Do I have to load it into ODIN mode whilst Odin is running on my PC?

Thank you for the help, although my problem is not dealt with still. I have completed the steps that you had suggested, thoroughly and repeatedly, yet there is no hope for a permanent, or even temporary fix for my mobile.
Windows isn't displaying any correlation between my PC and phone, no driver software auto-installs and no sign of the device being located in the Device Manager, not even under an "Unknown device".
Is this a problem for most Ace II devices? Or am I missing something that is too obvious to consider so seriously?

Porobu once told me something like:
1. Uninstall kies and sammy usb drivers
2. Install kies again, it should promt to install USB drivers.
3. Plug in phone to pc in DL mode.
I'm not sure what you mean in your 1st post so im assuming you have yet to try this. Works for me

When do I plug the USB into the phone and boot my phone into download mode? As soon as the drivers are installed via Kies?

After kies installation complete(dont have to open), boot phone to download mode, connect to cable and plug to pc

It sounds like a broken microusb port but try something first.
Download ubuntu or any other live cd linux distro
Boot it on your pc. You dont need to install anything.
Open a terminal
*Plug the phone while it is turned on to the PC
Write in the terminal 'lsusb' without the quotes and press enter
Something like Samsung android device or MTP device should appear.
If it doesnt appear power off the phone and go to odin mode and repeat from the * the steps

I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:

Windows? If, yes windows drivers are the problem.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?

i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?

What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.

You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!

I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.

Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

Driver issues win 10
Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!
