[Q] Root the Charge without computer - Verizon Droid Charge

Guys-
In a quandry - I should have rooted a couple months ago. I cannot get my Charge to recogize a USB connection with the comptuter. Computer recognizes something is trying to connect but computer gives me a USB Device Not Recognized message. It charges the phone when connected to the computer but doesn't ask me how I want to use the phone (as a mass storage device or media player) any more.
To make a long story short, I have tried everything - different USB cables, different USB ports, different computers, USB debug on and off, Ask on Connection and Mass Storage settings on and off. Have even gone thru several master resets of the phone and still will not recognize a computer connection.
Would love to root and hold on to this thing for at least a little longer, so my last thought is to ask if it's possible to root this device without a computer connection. From what I've read through on some other forum threads it's possible with some phones. I'm hoping this one can manage it.
Thanks, in advance.

While I'm certainly no expert, I am pretty sure its impossible to do what you're asking.

Yep, it's no HTC, so you need a computer to flash the custom recovery.

Your computer is seeing something. Sure seems like a driver problem. What os is your computer running?

I would make sure that you have the appropriate drivers installed first.

Drivers not necessary. I was able to plug into, and connect with, no less than four different computers at work and home on a regular basis for approx. 1 yr 10 months without ever having to install a driver, and I am quite sure that they didn't just download automatically (never saw that happen). Now I need one?
Operating systems on the computers have been Win XP, Win 7 Home and Win 7 Pro.
I suspect that its a physical issue inside the micro USB port in the phone thats the issue since no one has any other solutions.

perhaps you already the drivers and now there has been update. just saying, won't hurt until you try it. computers can be finicky that way sometimes.
For what it is worth, here are my steps:
phone settings: USB debugging enabled; ask on connection (when connected, place phone in "mass storage")
PC settings: download/install all samsung drivers applicable with this phone; reboot computer; use OEM cable only
then, follow steps from the rooting thread.
also, do you have an SDcard? if not, that could be an/the issue (either you need one, or the one you have is corrupted). often times, my computer will ask me to repair my sdcard - I usually hit no. after plugging it in, give it at least 5 minutes to secure a connection.
hope this helps.

I know that I had to, for whatever reason, manually download & install the drivers for my Win7 system before I could fully connect my phone to computer. Had similar issues with Motorola phones and ASUS T300T tablet. Windows always works? Not in my experience and I do this for a living (computers). :banghead:

Sorry guys - I've tried all of that. With SD card in, with it out, with battery in, battery out, sim card in/out. Literally every variant.
And the great thing is - show stopper here - I went to the Samsung website to download a driver a few weeks back, and the driver does not install correctly!! It just won't install - poops out somewhere (driver not installed properly message). Tried this on one Win 7 computer and one with XP. With firewalls on and off. It's like Samsung doesn't have their you-know-what together.

[Q] Phone doesn't connect to my PC

I posted this on a forum that I thought it applied to but the one answer I got did not work, I've done searches everywhere and have not seen a solution. There were a couple of similar problems for other phones but these fixes did not work for the infuse, so . . .
I Bought the infuse on day one. Installed Kies 2.0.0.11044_11_3. Phone not recognized, installed drivers, researched and learned the truth about Kies. Phone would not be recognized but at least installing Kies made the phone visible to the PC, so I knew I could root if I so desired, read up about rooting looked over the forums, learned my phone and finally thought I was ready. The phone had other plans.
Decided the other day that I was ready to root. Plugged in the phone but it no longer showed up in my PC running Windows 7 64 bit. Something about the phones compatibility with my system changed. Tried to install a newer version of Kies 2.2.1.11053_99_3 yesterday for the drivers, reinstalled drivers, activated USB debugging, plugged the phone in started up SuperOneClick and . . . still nothing happened. So I deactivated USB debugging and started over. Followed all the directions in the root posts and and SuperOneClick threads . . .
But somehow between day one and today my Windows 7 64 bit system does not know that the phone is plugged into it.
When I plug the phone into USB the phone asks me how I want to interact with the computer, Kies (Firmware Update); Media player: Mass storage. But the computer shows nothing. Device Manager doesn't list the phone, Windows Explorer doesn't show the phone, Devices and Printers window shows everything that's connected but NOT the phone, it's as if I plugged nothing into the computer. These places don't even show unknown device. The phone is charging so I know that it's plugged in, but it doesn't seem to be communicating with the PC. I've re-booted, re-installed, reviewed, rewired and re-alized that I have no clue what happened. (Tried different cables, different USB ports different times of the day)
It worked once upon a time, I tried rolling back restore points and disabling my kaspersky 2011, I've followed all rooting instructions in these threads to no avail.
Thinking about restoring phone to factory settings as a last resort. Got this reply in another thread (sorry about posting multiple threads, but I'm at wit's end.):
Try removing all instances of the Infuse coming in contact with your system using USBDeView. Also, how does it look in Disk Management? (Start button > search for "Computer Management" > Storage > Disk Management) Does the Infuse show up there as removable storage?
My answer: Tried it, didn't work, oh wait, didn't run USBDeView as administrator, re-tried as administrator and uninstalled all instances of Samsung i-997, then tried to plug the phone back in and still nothing.
Also not in Computer Management or Device manager either. Is there a way to uninstall any drivers that I have and then re-install them?
I did a factory reset, plugged the phone in and still nothing. Had to spend two days re-installing apps and re-configuring launchers . . .
I am now ready to hurl my phone out into traffic to see if that will help, but before I do I'm hoping someone here may have the answer I need.
. . . please . . .
If you are trying to root super one click will work. It worked on my infuse. First see if you can connect using mass storage. If you can access the files on your phone you are good. On win 7 64 bit it should just pop up to view the files. After that unmount and unplug the cable. Enable USB debugging and reconnect. Run super one click and it should work. Not every time does super one click work on the first run. I believe I had to unplug and reconnect a second time for it to work. But I did use super one click to root my phone. I was also using the drivers for the captivate at the time. If you need more help let me know.

FYI, drivers are NOT needed for USB mass storage, just to be clear.
Thanks for the reply, but that didn't work. I tried it exactly as you stated but it didn't "pop up" I ran SOC anyway and it got hung up "Waiting for device..." And a dos prompt window opened and just hung there.

at least for me (win7 64bit) mass storage mode DOES require drivers. Or else PC just tries to load both SD cards as external drives. I had a hell of a time getting my laptop to recognize the phone. What worked for me was I ended up installing both kies and kies mini. when neither of those worked i tried the Samsung pcl connect and that didnt work. There was a link on the ATT site for usb drivers for it. A combination of both the samsung pc connect drivers and the ATT USB driver works for me. Must be something to do with win7 recognizing it as an MP3 player when in music mode and a EXT drive when is mass storage.

You just contradicted yourself there. The phone's SD cards appearing as external drives IS mass storage mode. Mass storage mode does not require drivers.
Appearing as an MP3 player uses the MTP protocol, which is NOT Mass Storage mode, which is why it does require drivers.
ADB also requires drivers.
http://www.samsung.com/us/support/downloads/SGH-I997ZKAATT
Thanks, but same problem. After installing these drivers, the phone just doesn't show when plugged in. The next thing is to find a Samsung store (or AT&T store) and see if there's something wrong with the phone's usb port.
Definitely one advantage of picking your phone up at a store... if possible.
My CSR played with the phone on the computer for 10 min., said he was transferring sim contacts.

i am having same problems
for the past year i have had a captivate and i have flashed it probably with every rom made by every developer here. i have flashed kernals modems you name it i have done it the phone was incredible i never had one problem till i got the infuse when i first got the phone i rooted it and had a lot of problems but after 5 or 6 hrs i finally was successful. i then could not get the phone to connect to my win 7 pc i then took out the mem card and put my roms on that then transfer them to my phone flash ect but to this day i can not get the pc to transfer files through usb. when i hook the phone up the drives show up but are faint then i connect usb on phone the drives become bold but when i try to transfer files or open drive in explorer the computer lags and the green bar slowly goes across the bar get to the almost end and locks up. my main concern is that there might be something wrong with the phone. at this point i cant even odin it back to factory. from what i have read it is more of a common problem than just one or two people. please help?
ps just flashed maxq-kk2-b10 and it rocks !!
Yeah I have all of the same problems. It must be this phone just has crap drivers.
Sometimes I get the PC to recognize the phone once. Then if I disconnect the phone for some reason then reconnect it is no longer recognized. I need to reboot the computer to get it to be recognized.
I have just come to the conclusion that Samsung's PC drivers are total rubbish for this phone.
Hi!
I have the same problem. I tried connect my infuse to 5 differend PC, with different cables, different OS, but still NOTHING. PC just didn`t know that phone is connected. As a result I can`t reflash it with ODIN or CWM, because for install CWM I need make root first, but Superoneclick didn`t see the phone also.
There is some way to make root on this phone WITHOUT connection to PC ?
try getting a new data cable, the charging part of the cable may still work but the data transfer part may have stopped working-(happened with my dads Atrix 4G after buying a new data cable for $6 at walmart the computer once again recognized it)
so go to your store of preference that sells electronic cables
buy a new data/charging cable-***MAKE SURE IT SAYS SOMETHING ABOUT DATA TRANSFER OR FILE TRANSFER!!!***
shouldn't cost more than $10 depending where you go-like i said my dad got one for $6 and his phone uses the same cable as my infuse...i think all smart phones use the same cable actually.

This is 100% not data cable problem. not driver problem and not PC problem.
I am sure, because I have 2 Infuse and one of them work fine with the same stuff. This is something wrong with the phone hardware or software.
How can I root INFUSE without PC? There is some *.apk or scripts ?

One more USB question...

Hi there...
A quick question about the USB...
Is is at all possible to have a USB-port that can still charge the phone, but at the same time is "dead" when you try to connect the phone to the computer ??
I have also asked about it here:
http://forum.xda-developers.com/showthread.php?t=1179171
The story is that the Phone (SonyEricsson X10i) can be charged fine, but when i connect it to the computer, my computer say that the hardware is not recognized, nomatter if it is in flash-mode, mounted from recovery or in the normal way.
And the phone donĀ“t even show anything about USB connection in the status bar eigther.
I have tried 5 different computers now, and 2 different usb cables.
I have also a X10 mini and a Desire HD that works fine on all the computers and both cables.
I have tried to remove software, remove drivers, clean computers, reboot, check the memory-card in the phone, install software and drivers and all other things i can think off...
It is two windows 7 and three windows XP computers btw.
So is it at all possible that the phone can still be charged, but data-connection fail ?
As i see it, there must be some kind of data-exchange or else the computers would not even say "hardware not recognized"...?!?
I'm not quite sure I understood your question correctly, but let's see if this helps:
I used to have phone that didn't have drivers for Windows I used at the time (I think it was Windows 7). That meant that Windows wouldn't recognize it (when plugged via USB cable) and will not therefore provide power to that USB port (hence the phone will not charge).
I was able to get around the problem by going to the device manager, locating the relevant "unknown device" and force installing some random drivers for it -- I don't even remember what it was that I picked -- something that Windows would allow me to do. Of course the port wouldn't work as a data connection like this, but since Windows now 'knew' the device, it powered the USB port and I was able to charge my phone from it.
My problem is that I actually can charge the phone ok...
But I am not able to make a data connection between the computer and the phone at all...
My question is then, if the usb connector in my phone can somehow be broken even though I am still able to charge the phone...?

I'm fairly sure that yes, the contacts or the controller can be broken so that you can still charge but be unable to establish data connection.

[Q] Help: GT-P6210 not detected by W7 32 bit Enterprise at all.

Hi,
Quick background: Former sys admin with some Unix experience. Already own a Toshiba Thrive rooted with CWM. Gave that to the wife and got me the GT 7+. Read the forum here prior to buying. Rooted on day one.
Stats: GT-P6210 Build: HTJ85B.UEKL1 P6210UEKL1
PC: Windows 7 21 Bit Enterprise SP1
Kies: Kies_2.1.1.11124_17_6
Later on the first day, after installing aps, I installed latest version of Kies and plugged it in with the supplied usb cable in order to transfer some files to my Sandisk 32Gb microsd. Kies already running and debugging off as per the instructions. Results: Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing.
I unplugged and tried the other 3 ports. 2nd port gives me same result and on the 3 & 4 port I lose the tab's MTP notice and it begins charging.
So, this is what I have done in order:
1. Re-installed Kies--->same result. No MTP notice on tab.
2. Debugging on--->same
3. Tried in on my room mate's W7 machine---> Alas! I get a driver installation and I am able to see both drives. I quickly unplugged and thanked him.
4. Cleaned my pc by:
a. Deleting all USB controllers
b. Deleting all USB installations on registry (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSBSTOR)
c. CCLEANER the whole system.
d. Turn off. Pull off battery. Press power button to drain motherboard.
e. Restart and re-install USB controllers.
f. Restart again.
5. Plug in again--->Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing.
6. Pull my hair, bang my head, wished I would have kept the Thrive. (just plug, and drag and drop)
Left it plugged to the pc overnight. Next morning I see the found new device on systray and it is trying to find drivers. I quickly open Kies and see some activity as it tries to connect. and after a few seconds, it stops. Result: No drivers installed, no Kies recognition, no drive letters, nothing.
8. At this point I ask my room mate to let me plug in on his pc to see if he still sees it and nothing happens on his pc.
9. I wipe the table back to stock.--->Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing. Then after I tried other ports, it begins charging and I lose the MTP notice.
10. I re-roo,t reconfigure the beast, and do a backup. Tablet is running smooth as silk, but it never connects. This all happened in the last three days.
11. Last thing I did, as I am writing this with the tablet plugged in to the pc and MTP notice on, was to un-mount the microsd and remount. MTP re-initializes and it does nothing.
I may be suspecting a cable and unfortunately, I am in no position to get my hands on another one in a timely manner. At this point, I could reflash back to a stock firmware, send back to amazon and wait for another one to come in three to four weeks (I am deployed to a remote area) and I just don't want to do that.
The tab runs great. Love the size and speed. I guess I can continue taking out the microsd card out every time I want to add a file, but I am afraid that it may eventually end up ruining the card and possibly the tablet.
Please help. I have scoured the internet, but all I ever find is solutions that I already have tried.
Thanks in advance,
Sal
you could use adb over wifi.. There are a few apps in the market for this. Does adb recognize the tab when its plugged in via USB?
Also try Android commander, it is a GUI based adb server, you should be able to navigate to sdcard/extstorages/ and your external card should be there
Sent from my HTC Glacier using Tapatalk
You could also use a file explorer like Root Explorer and Dropbox to transfer files back and forth.
Have you tried a different USB port on the PC? like one round the back.
Also, try without the sdcard in.
Ticked/unticked USB development/debugging on the tablet?
If it works on another computer though it would suggest its your own PC which has the problem, not the tablet.
tried with Linux on the same PC?
Does Odin see the tablet when in download mode?
if you have clockwork mod recovery, doesn't that have a USB mount option ? It does on my gs 2. My tab isn't with me to check.
Oh and kies has an option to reinstall the driver. Did you try with the older version of kies again?

I have done all that you mentioned with the exception of Linux and Odin. I am not going to get into Linux as that would start a whole other project. I will install ADB to see if I can force the drivers.
I just tried the CWM mount USB mount but get "E: Unable to open ums lunfile (No such file or directory)"
Also, on my friend's pc worked once but not after that.
I will continue to explore the ODIN suggestion.

EDIT: Sorry, I see now the dropbox suggestion. Yes that would work for smaller files, but I am not sure that dropbox can handle movie size files. It would be a last resort solution.
Thanks,

Adb is probably going to be your best bet. It can be a pain to set up at times, but in the long run is a must have for any Android device. Kies normally installs the drivers that adb uses, so hopefully you can get them to install. If it still doesn't work I would suggest swapping it out for a new tab, as much as that sucks. If you need help, I constantly check these forums, so I should be able to provide some support

Well, got ADB installed and running. Set the path and ran it. Plug the tab with debugging clicked on, and got "MTP connected" on the tab's screen. At this point I am excited since I never seen the "MTP connected " on debug mode. I typed the "adb devices" command and got "List of devices attached" ___________________.
Yep, blank. Obviously the pc is not seeing it. My conclusions are the following:
1. Bad cable
2. Bad device
The fact that it recognized once on my room mates' pc and then none at all, and the fact that it was recognized on my pc for a brief random time, then it means that the device can't handshake with the motherboard and thus is a communication issue.
I'll try my luck with Samsung tech support and see if they can replace the cable.
Just thought of something, would installing Windows XP Mode under a Windows Virtual PC recognize new devices or just feed from the Windows 7 library?

I placed the tab on download mode and queried it from adb and got nothing. I then queried it via ODIN3 and got no response as well.
I have come to terms that it has to be the device or the USB cable. Just ordered two (yes, two) different type cables to test out the theory. If they don't do it, then I am sending the tab back to Amazon.
It takes about a week to get stuff shipped where I am at so I'll check in later and report.
Sal
Just an update.
I bought a cheap cable from Amazon for $ 3.31 US to test the cable theory and guess what? It worked.
Curse you Samsung for your lack of QC with your cables. I have read throughout most of the forums (not just this one) and it seems that cables for these devices are notoriously finicky.
While on the one hand, I am glad that I got a cable that works, Samsung owes me over thirty hours of my life that I had to spend on troubleshooting a brand new device.
The part that I hate the most is that when I tried to contact Samsung's tech support, all they kept telling me is that it must be my pc even after I told them all the troubleshooting that I had done. Yes, they played the blame game.
My Toshiba Thrive worked right out of the box with a standard micro usb cable.
Ok. Rant off.
Sal
Glad to hear you got it working. Personally I have a ftp server set up on my comp that I use to transfer files back and forth. Much easier IMO than having a cable every time I need something transferred

[Q] Trouble connecting Nexus 5 to new laptop in MTP mode

Not sure how many would read such a long post for a question, but here goes...
Any help is appreciated!!
1. Problem
In short, I plugged in my Nexus 5 to my laptop in MTP mode, it does not show up in "My Computer".
I just wanted to transfer files to my phone via USB, not even using ADB yet.
I have yet to solve the problem after googling around for a bit.
Relevant XDA threads that I remember reading are this, this, this, this and this.
I have tried numerous combinations of (un)plugging my phone / (un)installing drivers / rebooting my laptop and phone / switching usb ports / turning USB debugging on and off / connect in PTP mode / ...
As a workaround, I am now transferring files using the AirDroid app, which is really convenient with acceptable speed.
Still, it would be nice to know why the problem occurred and see if others have similar problem.
Below I will describe the devices I have on hand and more details on the failures I have encountered will follow.
2. My Devices
A. an old Galaxy Note
B. the new Nexus 5 with the stock micro USB cord
C. new laptop
- 64-bit Windows 8 Pro (not upgraded to 8.1 yet)
- only USB 3.0 ports
D. old laptop
- 32-bit Windows XP Home
- only USB 2.0 ports
3. Details
Scenario A. Nexus 5 not showing up in "My Computer"
Naturally, the first thing I tried is to simply plug my Nexus 5 in to my new laptop. I was used to Android devices working just like that!
However, my Nexus 5 does not show up in "My Computer" after a loooong wait.
On a closer look, my Nexus 5 (only) appears in the "Device Manager" under "Portable Devices" as "MTP USB Device".
It shows my device to be "working properly". However, I cannot uninstall/disable it when my phone is plugged in (normal?)
Frustrated, I decided to unplug my phone. I have the option to "Unplug Nexus 5" under "Safely Remove Hardware", but the operation always times out, so I simply unplugged it.
Then I tried with my Note using the same cable. It works flawlessly either in MTP mode or Mass Storage mode.
Scenario B. Nexus 5 shows up, but is really sloooooooooooooow
At some point, I turned on USB debugging.
With USB debugging on, my phone appears under "Portable Devices" as "Nexus 5" (and in some other places according to what drivers I have installed).
I was quite pleased for a few seconds as my Nexus 5 now shows up in "My Computer"!
However, it took a few minutes to list the folders I have under my phone's internal storage.
Attempting to copy a 12MB file to it gives an estimated time of over 2 hours.
Scenario C. Success?
After tinkering with it for some time to no avail, I was beginning to worry if I have gotten a defective hardware.
Then I remembered I had an old laptop stashed somewhere, so I tried connecting my Nexus 5 to that.
And... voila! It works without a hitch (MTP mode, USB debugging off).
A maybe useful note is that I have used both the old and new laptops to transfer files to my Note before.
4. Possible causes
While many seems to have solved the issue by simply unplugging and letting Windows reinstall the drivers, I have no such luck.
I sincerely hope that it is not due to any hardware defects since
a) my Note can talk to my new laptop through the same micro USB with no problems, and
b) my Nexus 5 can talk to my old laptop.
I feel that this is a driver-related issue but I am not sure.
Is it possible that there are compatibility issues with using USB 3.0 port (which should be backward compatible...) or a 64-bit Win 8 Pro?
Any help is appreciated!
It is so strange..
I just bought a USB 2.0 hub and connected my phone to my new laptop through it.
Guess what... it works perfectly!
Apparently my problem was that my new laptop only had USB 3.0 ports for me to test on?
Doesn't make sense... thought 3.0 is backward compatible and my old Note works on it!
Maybe I'm missing something but I'm happy it is solved for me now
This solution worked for me. Go to http://forum.xda-developers.com/showthread.php?t=2512549 and see post #5. Be sure to thank n7of9 for the link and WugFresh for his toolkit solution. Enjoy.
Hey,
I basically seem to have the same problem as you do.
My laptop also only has USB 3.0 ports and Windows 8.1 Pro 64-bit installed.
The Nexus 5 doesn't get installed, in MTP mode it is just shown with the yellow exclamation mark in Device Manager. Downloading different USB drivers including Google's and trying to manually install it doesn't work at all. I specifically checked that all older similar drivers are gone, so I doubt that older Android devices could be interfering.
On the other hand, as you noted, using an older computer with USB 2.0 works perfectly, I had the same result.
To be honest, I'm not much of a developer or Android tinkerer, so I'm not really making any progreess... In the end, I think I will follow your example and test it with a USB 2.0 adapter.
Did you manage to get it to work without this workaround?
Kind regards! :fingers-crossed:
I'm using Linux Mint. Just plug the Nexus in. It shows up as a folder. No hassle

I had a lot of issues with my S3 and my work computer (windows XP SP3) and it was because I had half installed some USB driver that windows tried installing.
I fixed the problem in device manager by manually uninstalling EVERY SINGLE USB DEVICE attached to the computer while I had my phone plugged in.
Word of caution: You'll probably uninstall your mouse/keyboard doing this.
Once everything was uninstalled I reinstalled the Samsung drivers and it worked fine.
The same computer only required me to install the Google drivers for my N5. If I enable USB debugging, I all of a sudden can't install MTP drivers, but USB debugging disabled works fine.
USB & MTP mode
I have the same problem with my Nexus 5. The only workaround to transfer files to my phone from a computer via USB cable is to enable USB debuging, set the phone to PTP mode instead of MTP and then it shows in My Computer as a camera. I can only access the DCIM and Pictures folders but for now I have to settle for this...I copy all the files I need to let's say Pictures and then using a file explorer (on the phone) I cut and paste them to the folders I wish...e.g. movies to Movies, music to Music and so on...
I had same problem. Developer Mode...USB Debugging ON worked.
I have this problem too, but I got it to work using a galaxy s3 cable. for some reasons the cable that came with N5 did not work.
Its usually just missing drivers.. You can get them straight from Google or a toolkit as mentioned! (P.s you need to download a little applet like thing from Google if you want to hook up your Mac to your n5)
See andoid.com/filetransfer for the drivers.
This worked for me when all else failed: http://forum.xda-developers.com/showpost.php?p=35854664&postcount=7
Hope that helps!
The problem I am having now connecting is that my phone got wet recently. I dried it immediately and used dessicant to withrow the water and now it works (sort of). Now when I plug my phone into my pc, the usb debugging icon doesn't even show up.
I tried connecting to both my work pc and home laptop and they both say the same thing, that the usb device has malfunstioned and that windows doesn't recognize it.
Is it time for a new phone?

Sounds like the usb is shorting. How long did you let it dry. Give it more time and try it again.

Yeah maybe thats what happened. It's been drying now for about a week. The screen was the major problem at first but has since dried there mostly.
Hopefully it will come back. Would suck to have to buy a new phone because of that.
Thanks. :good:
MTP connecting problem solved
Going back to the subject of the thread: I am pretty sure that ADB drivers and SDK (I am confident that a lot of nexus users have their devices rooted and that means they must have the above installed) is what is causing some sort of conflict when trying to connect the Nexus 5 as MTP. After I reinstalled the windows (W8) on my computer and connected my Nexus 5 it took @1-2 minutes to auto install the drivers and then worked fine...I have no ideea what happens if I install ADB and SDK again...

If you tell the SDK not to install the drivers it'll be fine
The simplest and shortest way to connect google nexus5 with PC as MTP(Media device)
When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).
What you have to do is:
Unplug the device from the computer
Go to Settings -> Storage.
In the ActionBar, click the option menu and choose "USB computer connection".
Then select Media device(MTP) or Camera(PTP) based on your requirement...
Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection..
I hope this will help!

Resolved. nexus 5 PC Connectivity
hackdisk said:
Not sure how many would read such a long post for a question, but here goes...
Any help is appreciated!!
1. Problem
In short, I plugged in my Nexus 5 to my laptop in MTP mode, it does not show up in "My Computer".
I just wanted to transfer files to my phone via USB, not even using ADB yet.
I have yet to solve the problem after googling around for a bit.
Relevant XDA threads that I remember reading are this, this, this, this and this.
I have tried numerous combinations of (un)plugging my phone / (un)installing drivers / rebooting my laptop and phone / switching usb ports / turning USB debugging on and off / connect in PTP mode / ...
As a workaround, I am now transferring files using the AirDroid app, which is really convenient with acceptable speed.
Still, it would be nice to know why the problem occurred and see if others have similar problem.
Below I will describe the devices I have on hand and more details on the failures I have encountered will follow.
2. My Devices
A. an old Galaxy Note
B. the new Nexus 5 with the stock micro USB cord
C. new laptop
- 64-bit Windows 8 Pro (not upgraded to 8.1 yet)
- only USB 3.0 ports
D. old laptop
- 32-bit Windows XP Home
- only USB 2.0 ports
3. Details
Scenario A. Nexus 5 not showing up in "My Computer"
Naturally, the first thing I tried is to simply plug my Nexus 5 in to my new laptop. I was used to Android devices working just like that!
However, my Nexus 5 does not show up in "My Computer" after a loooong wait.
On a closer look, my Nexus 5 (only) appears in the "Device Manager" under "Portable Devices" as "MTP USB Device".
It shows my device to be "working properly". However, I cannot uninstall/disable it when my phone is plugged in (normal?)
Frustrated, I decided to unplug my phone. I have the option to "Unplug Nexus 5" under "Safely Remove Hardware", but the operation always times out, so I simply unplugged it.
Then I tried with my Note using the same cable. It works flawlessly either in MTP mode or Mass Storage mode.
Scenario B. Nexus 5 shows up, but is really sloooooooooooooow
At some point, I turned on USB debugging.
With USB debugging on, my phone appears under "Portable Devices" as "Nexus 5" (and in some other places according to what drivers I have installed).
I was quite pleased for a few seconds as my Nexus 5 now shows up in "My Computer"!
However, it took a few minutes to list the folders I have under my phone's internal storage.

Hello !!!
I faced the same problem with mine...
Couldn't connect my phone with my laptop.
It installs the driver but not displaying the folder in my computer.
I uninstalled the Existing samsung driver in control panel.
Then the issue has been solved,
Or uninstall previous mobile's drivers
Try this!?!
Search for Universal Driver here in XDA. Had the same problem most of you are having. First try and BAM! Works like a champ...
NEXUS 5
Problem solved for me
I have no more issues what-so-ever after I unninstalled ADB & SKD drivers...Windows(8) installed my phone by itself after a restart and it works as it should in MTP mode and PTP mode.

PC connection

Hello all. I have a problem that is not unique, but I cannot for the life of me seem to fix it.
My S6 will not stay connected to my PC so I can transfer files, use Kies, SmartSwitch, or anything. Sometimes I hear the Windows notification that it's plugged in, but even when I do, it goes back and forth between being recognized and not. Most of the time it doesn't even show up in Device Manager.
I'm currently running Windows 10, but it did the same thing on Windows 8.1.
I have downloaded the Samsung USB drivers as well as allowed Kies and SmartSwitch to install them.
Thinking my Windows 10 being upgraded from 8.1 without a full wipe carried over whatever problem was in 8.1, I did a full wipe of my PC and reloaded Windows 10 clean. That also didn't help. Note: when I first installed Windows 10 clean, my PC didn't recognize my phone at all. It just acted like a charger. After I installed the Samsung USB drivers, it started making the 'connecting' and 'disconnecting' sounds. Also, the most I got Windows to recognize my phone was for about 5 seconds, and that was right after turning off USB debugging. But with it on or off, it still won't stay connected.
And yes, I've made sure (when the phone has connected for a second or two) that it was on MTP. But... I've tried the camera mode as well.
This makes it not only impossible to move files easily between my phone and PC, but also to use Odin.
I've read many posts where people have this problem, but everyone just tells them to go download the Samsung USB driver, and after having done so three different ways, I can say it doesn't work for me.
Anyone who could solve this for me... well... I'd be willing to donate a bit of money to the cause of your choosing, including yourself.
No one else has experienced this or is willing to shed some light on this?
When I had that issue with my nexus 7 I switched out the USB cable for a different one. Seems to have improved.

Try downgrading to windows 7. Before you connect your phone to the computer install necessary drivers, samsung driver and kies. Use USB 3.0.

Yeah, I'm definitely not going to downgrade to Win7. That would be 2 Windows versions ago for me. I've installed every driver available, from Samsung's (with and without Kies) to Google's universal Android USB drivers, and none have worked. I've also tried USB 3.0 and 2.0 ports (I have both on my laptop).

Hey, did you try connecting other usb devices to your pc to see if they connect? furthermore, you should also try to connect your phone to another pc to check if there is a USB port problem with your PC/Phone
For me the standard USB cable gives this problem, with another cable it works perfectly. So try another cable
Sent from my SM-G920F using XDA Free mobile app
Hi, everybody.
May you help me, please? My S6 SM-G920F, also is not recognised by windows 7. Smart Switch say S6 dont connect in emergency mode. I supose they means "emergency calls only", is that? I had bought the phone locked to O2 but I live in Portugal and I have no valid O2 SIM card. I bought an unlock SRS by TomMobile because I dont knew that needs a USB cable connection. What can I do, please?
Thanks in advance. AS

iphone and Samsung S6 same issues
Hello wvcadle,
I have the same issue and it is quite frustrating. Did you find a solution? As some additional info for you. My i-phone was doing the same thing on my computer. I thought it was the phone and I upgraded to a Samsung S6. It does the same thing as the I-phone, what you described and it works fine with other PCs. SO must be computer related. My bet is windows and my IT recommend a full wipe and reinstall of windows. We run Windows 7 Professional.

its not usb port or cable problem... this problem starts when someone trying to root ... & damage efs partition..
Its just Cable problem my friend.
Find and buy a reliable usb cable. You stated all options and fixes but you never been able to speak of your cable
For those whose saying that root and damaged efs will affect your phone connection to your pc, he's wrong . Rooting and corrupted efs partition doesnt have to do with windows driver etc.
Just think out of the box.
If it did not work with your pc. Then switch to other pc with smart switch & samsung usb driver installed.
I prefer installing samsung usb driver and then smart switch.
If it didnt work, try using different cables.
If it didnt work again, use other samsung phone and see if it connects.
And so on ...
Having exactly the same issue...
Started just today (yesterday and previously no problems experienced, phone would just connect & be visible and available for data tfr, no problems). Today, no go. To be clear, it's Galaxy S6 128 gb running Lollipop, which no longer connects for data tfr via USB to laptop running win7 ultimate. It only connects and charges. I have checked for updates for both windows and Android. There are none outstanding. I have downloaded & reinstalled samsung USB drivers on laptop. No change. I have tried 4 different USB cables, 2 new, and the cable supplied with phone. No go. I have tried these cables in all USB ports on laptop. I have tested other devices in all USB ports and connectivity to laptop with other devices is fine. I have tried connecting phone to another PC, same issue (only charging). I have done the developer thing and switched USB debugging on, no change, and off again, rebooted both devices multiple times, all with no change. Yesterday all was good, today - nada. Anyone got any other suggestions?? Wit's end, reached.
It's been said many times already, but I had this problem and it was the original white cord that came with the phone. It would not stay connected to my laptop nor would it stay connected to the charger. It sat there blinking and making the charge cord inserted sound when plugged into the charger/computer. I changed cables and it went away.
I remember picking the phone up one night in bed and forgot the charging cord was attached. I reached the end of the line and it yanked out of my hand and fell to the ground. This is the only thing I can think of that damaged the cord. I was lucky it didn't damage the charge port on the phone. So you could have a screwed up charge port on the phone if you've tried new cords with no avail. I wouldn't encourage it but sometimes the charging fin can be bent back into place to make a better connection....had to do this on a dell tablet.
Also, if you're using lock screen or fingerprint, I believe you have to unlock the phone after connecting to PC to access and transfer stuffs - just a thought.

Thanks for the input - it's not a lock screen issue - I've tried connecting with screen locked (then unlocking when connected) - and connecting with screen unlocked, and I don't use the fingerprint security option. No changes observed. I have had concerns about the charging fin, but I am always careful connecting and careful with the phone generally - it looks OK and I'm rather loath to start bending it about in case I just f**k it up entirely. At least it still charges OK. Looks like I might have to bite the bullet, wipe it and take it to a Samsung repair centre. At least it's still under first year warranty. Thanks for your time talroot.
Original white cable did not work from day 1. Fast Charging is working fine but USB connection and tethering is a hell. You need a new cable and a good quality, not some cheep stuff.
Samsung really disappointed me because I owned many of their devices and most of them had some small issues, but after this in s6 edge and overheating issue (especially when using Gear VR) I will not by from Samsung anymore.
just for the record....
...my phone started connecting to laptop again. After about 3 weeks of non-connectivity, I connected again to charge and *ding* it was an external USB device once more. Same cable as before. Doesn't make any sense, but there it is. Thank you everyone for your input.
