Computer won't recognize friends ns4g but does mine?

I wanted to root my friends ns4g but my of won't recognize it. He had a galaxy s 2 as well and it was the same issue.
I installed pdanet, Samsung drivers, different USB cords, nothing!
When I plug it in nothing happens, then about 5 mins later, USB not recognized. I manually tried to put the .inf file through the windows 7 wizard and still nothing.
Like I said my ns4g works perfectly fine, when I plug his in nothing works at all. I don't understand this at all. I have a 64bit system and made sure everything was for that. Can anyone help me out?

Can you mount usb in either recovery (if applicable) and android? Have you tried with usb debugging enabled? Also, does it show you no android device is connected in device manager?

in device manager it only shows unknown usb device with "!" symbol. Yes for debugging, and cant boot into recovery, there is no recovery as its not rooted.
help someone please! lol

There was something i read about the fast charge widget messing up the ability of the nexus to properly connect to the computer and a fix. Part of its design is to block USB file transfer when connected to a computer. There were several phones that couldn't connect after loading the widget.
Before i go and waste a bunch of time researching and digging for this. I would like to know if your friend has installed the fastcharge widget on his phone.

lol, no his phone isnt rooted to get the fast charge patch even.
Its soo strange. I plug my phone all good, I plug his NS4G, no detection. It's strange.
Same thing happened when i was trying to root his tmobile gs2. No driver worked.

did you install tbe drivers by booting into bootloader while pluged in?

yeah, didnt work. Factory Reset the phone too.

Try a different USB port on PC and pull the battery for a min.

Try drivers from Samsung support page. It took me a bit. But usually the pdanet drivers work. You could try another pc that does not have the drivers for the nexus.

But windows automatically installs the drivers right? (if not found)

No...
It installs drivers if the device already has the same included...
Fit is not plug-and-play, which means you need to install drivers manually...or install kies...
Whichever you prefer...

Dont go for KIES .... !! It's a crap ..

You don't have to use it if you don't want. Installing Kies means you're installing USB drivers, you don't have to start kies everytime when you connect ur phone through usb. I've installed kies but never used it. I use it HIGHLY OCCASIONALLY.

Yup kies is waste of mem (if u ask me ) for drivers go to sammobile website registr n check our phn specific drivers its just around 25mb file dats easy if u dnt want kies

I found it easier to install drivers kies then uninstall kies

Even after installing kies it is still charging. Device is not connected to kies.
hey i am using the usb cable of galaxy ace. is it the problem? but i think these cables can be used on both the devices.

I use the same cable on 2 different blackberry's, my nokia 5310 and c3, samsung monte, and acer liquid metal...
So I don't think that's the problem...
Have you tried using a different computer?

yes i have triedon different computers also.. but its not working there too.

Hi.
I had the problem too. I did this to connect my phone:
1. Go in DownloadMode. Now, the computer must install drivers, like odin.
2. If the installation finished, hold down the Powerbutton for 10 seconds. It'll restart, if nothing happens try to start with holding the powerbutton again.
3. Then, if the phone is started, your computer finds the phone!
I'm not responsible for any damages!!!!

Problem with root!

So today I went to use noxious ninjas root method and started out fine, but after the first reboot someone called my phone and the root procedure stopped working. My phone is working without a problem but when I plug my phone into the computer, the computer won't recognize my phone. The phone just starts charging and won't connect to the computer at all. I've tried different computers and it's the same thing, it won't connect at all, it only charges. I'm pretty much a beginner to all this so any help would be appreciated.

Check settings->developer options --> usb debug should be checked.

Usb debug is checked and so is non market apps. I've tried restarting the phone and deleting/reinstalling the drivers and the program on my computer. It still only charges when I plug it in

What Os are you running on computer cause vista does that with my phone always has. windows 7 and xp play nice tho ?

I have vista on my desktop and windows 7 on my laptop. I used the desktop to try and root because the samsung drivers wouldn't correctly install on the laptop. I've always used the desktop with Vista and never had a problem.

I think something mess-up in your phone after you rooted. Best way just backup all your apps (not system app), Odin back to stock and see if it's working. If it's then try to re-root again. Make sure everything is working before you restore all your apps.

Did you try rebooting the computer and then plug in back in?

Yea I literally left my Rezound to charge on vista laptop overnight and after I unplugged every time then it would pop up new device found. It was stupid but 07 always worked... do u have Samsung drivers updated on both machines and rebooted then plug

Well it didn't fully root, I'll look into the Odin but ill have to read more into it before I attempt anything.

MTP is the worst protocol ever created. Nothing but problems. You are either rooted or your not. You can download Root Checker on Google Play to.

Phone detection by PC

I have completely lost connection with my computer. It does not detect the phone at all during standard usb to phone connection nor does odin recognize a phone being hooked up. Any suggestions? Thanks in advance for your help.

Try deleting the Samsung drivers on your computer and let Windows find them for you or switch usb ports or check out your Device manager and see if there are any problems in there... Assuming that you are running windows? Hope this helps...:good:

Options
1.try another computer
2. Dont use a usb hub
3.try a different usb port... stay a way from usb 3.0
4. It might be a bad usb cable
5. Uninstall the driver then reinstall them(install if youb dont have it)

Thanks for the advice guys. I tried a different cable, USB and deleting the drivers. It doesn't detect my phone at all after this.
I'm pretty sure it is an issue with my phone. I plugged my wife's s3 in and instant detection. I'm gonna call vzw and have a replacement sent.
Thanks again for the help.

Be sure debugging is off, or the drivers will not automatically download. Switch back on when you start using Odin

[Q] HTC Butterfly MTP Driver Error on Win7

Hi,
am a new HTC Butterfly user. I've installed HTC's Sync Manager on my Windows 7 (32bit) laptop. When I connect the phone via provided usb cable, I just kept getting MTP Driver error which does not allow me to link up with my laptop. Even the Sync Manager could not detect my phone. I've tried re-installing the sync mgr but failed too. Tried to update the device driver via auto windows update but nothing happened. Appreciate your kind advice and technical input on this problem.
Regards,
redwacko

With phone still connected to pc, just reboot.
If this fails, uninstall and reinstall.
