Hello Guys...GretoVerno here fellow Samsung Galaxy S Vibrant Owner...
I have this phone and everytime i connect it to usb i Get the Message
"USB Device Not Recognized" error message...I have installed all the drivers i could possible find on the internet and the error still pops up...i ahve tried using the phone in USB Debugging mode to no avail what so ever...
Someone Please help if there's a genius out there...I really love this phone
Uninstall the Samsung drivers off your computer. Then reinstall make sure that have the correct version windows 32 bit or 64 bit for the correct operating format. Make sure you give admin rights to it. you can find these drivers in the Noob bible by S15274N in the Gen section. I am assuming there is not a problem with your phone. If you have a friend, check it on their computer, that's an easy way to rule out phone issues. That should resolve what ever problem you have.
There ia another way to check, that is have a friend with odin (or you) and see if Odin recognizes, if it does, then you got it solved or at the very least Odin back to stock and reinstall a new rom, this will solve all these issues as well.
Hope you get it, good luck
Had an issue with my brother in laws comp not recognizing his vibrant. Took an hour or two to get his phone recognized. I think we ended up using the drivers from pdanet instead of the official danny drivers. First try getting your phone to work on another comp. Will help narrow down the issue by 50%

Windows cannot recognize my vibrant!
Hopefully someone can help me out as I am having the
same problem with my computer not recognizing my phone.
The thing is that I am already running Froyo stock 2.2
and at the time I was able to update it to 2.2 my
computer recognized my phone without a problem. I have
been reading the forums for a while now and the only
time anyone had this problem was when they first bought
the phone when it was released but here is my problem.
After updating Kies mini and installing the official
Samsung drivers from the Samsung website I plug in the
phone and i get the error that windows does not
recognize the device. I have tried this on Windows Xp
and Windows 7 on 2 different laptops and got the same
error everytime. So what I did was while on Windows Xp I
uninstalled the unknown driver and I kept plugging and
unplugging the phone and uninstalling the unknown driver
until I got my computer to finally recognize my phone.
Once my computer recognized my phone I Then started
downloading the recent update, when the download was
done as soon as my phone went into download mode my
computer kicked out my phone and gave me the error that
windows does not recognize the device and at that time
Kies mini gave me the emergency recovery notice which I
didnt have to use because the phone booted fine without
fail.
You should also know that prior to the recent
update from tmobile for minor bug fixes I tried to root
my vibrant using the superoneclick root program. Upon
doing this after fighting with my vibrant and my laptop
to communicate with each other my computer recognized
the phone and I attempted to root. Then I got the
looping message and at that time windows did not
recognize my device which then messed up my modem and I
had to do a system restore. So after weeks of fustration
trying to root and now not able to downlaod the recent
update I am now asking for your help as XDA has been
there for us all. I have tried samsung drivers, kies mini
drivers and pdanet drivers and get the same windows
doesn't recognize my device everytime. Does anyone have
any ideas as what I can do to get my computer to
recognize my phone as I can not do anything until my
computer and my vibrant get along. Your help is greatly
appreciated XDA thanks for all that you do!
do you guys have Samsung kies installd??

You know that's the only thing that I haven't tried should I pick one up from T-Mobile or were should I get one?
I am getting the same error and i tried a buddy's cord and it still did the same thing. Not really sure what happened. My phone was working fine just a few days ago. I am wondering if it has anything to do with the large amount of Windows Updates that just happened.
Try uninstalling your drivers and install these. I had the same problem and then I used this and it has worked on every computer. Heck even worked when I hooked up my SGS2

I had the same issue. It is a phone problem and I had to get a warranty replacement. No combo of cables or drivers would fix mine.
Well after uninstalling and reinstalling, trying new drivers, restarting countless number of times, troubleshooting through the device manager, I had the genius idea to restart my phone in a last ditch effort before i gave up and it worked.
Now i feel somewhat like a dodo. Rule #1 - Restart

Have you rebooted since you installed the drivers?
Well I tried those drivers from that link you provided and no dice. Im going to pick up a new usb cord from Tmobile tomorrow and see if that might be the problem. I can always use a 2nd cord for charging I guess.

That would be the logical next step.. just to verify, you have restarted the phone and computer since installing the drivers right? If you have then its most likely the cord. Its weird these cords seem to have been giving me problems more than any previously owned ones ie regular usb or even my amp cord which I step on and rip out the amp more than i'd like to admit

Makes sure that when you uninstall your drivers to restart your PC then reinstall and give a shot. Of course, also make sure you are using the right 64x or 86x driver.

Hey. Im brand new to this forum and to Android aswell since i came from Iphone. Yea im a noob and sorry if you notice bad english
So i received my SGS2 some days ago and after researching about root/custom roms and stuff, I decided to start with rootin my SGS2. i download Odin3 1.85 and superoneclick, i also liked litening rom v1.1 and downloaded that too.
So i turn on "USB debugging" and turn off the phone to enter "download mode" and when i try to connect to Odin, nothing shows up. And Windows bar tells me that usb is not recognised. But... flash drive/transferring files and connecting to Kies works just fine. Please help me, ive been sitting over 24 hours with this issue and ive restarted/uninstalled installed pretty much everything over and over again (kies/drivers/device) not windows though. Why wont Windows/odin recognise it in download mode???
And if possible, is there a way around to install litening rom??
Thats weird man....very very unlikely to happen...
Just tell us step by step with screen shots if possible then it becomes very easy for us to find where u r doing it wrong...ok ?
Turn off USB debugging .
reboot phone and PC .

This is driver issue.Try to find on kies an option to install the drivers again(i am not in front of my pc).Of course phone on and untick usb debugging

This is a driver problem. The Gadget Driver fails to get installed properly.
Make sure Windows Update are set to automatically find drivers for your devices.
I myself faced this problem. To rectify it I'd to try the same thing on a different machine and it worked flawlessly there.
The problem you're facing is that the Service Mode drivers are not getting installed, hence Odin is unable to recognize it.
Other possible fixes include, trying on different USB Ports, downloading Samsung PC Studio.
Thx for the replies everyone. Yea i figured its a driver issue, ill try the suggested actions incl samsung pc studio installing, and if its still not working i guess my last resort is using another pc or reinstalling windows on my own pc
In kies, i think in the tools menu, there is a install drivers option. This will fix the problem im sure. Not sure about pc studio having the same.

fyi, i reinstalled windows and updated everything and the driver connection issue is solved now. I should have done this from the beginning instead of freaking out for several midnight hours lol thx for the help everyone, hopefully the rooting and flashing process should happen painless now
if anyone has this problem too,
i had the same problem and for me closing kies helped.

Hi, background is this..
I have a D802-10C G2 that i rooted the stock 4.2.2 rom a while back using the post chinese method. Easy enough, all worked fine. no complaints. A couple of weeks ago i got offered the OTA 4.4 update, this failed due to the root. I then removed the root using the feature in super su. that seems to have worked as no apps or file managers etc could get root access. However, the OTA still wont work.
Now my problem is my phone will no longer be recognized by any operating system, on multiple computers. I have tried many ADB drivers, Windows 7 wont even detect the device, i've used every PC connect mode, USB debugging. However always the same result, it's as if i'm plugging in a blank usb cable into the computer. Nothing at all.
The only thing that does happen when i connect the phone to a computer is the phone starts to trickle charge. There is nothing detected in Device Manager in Windows 7 I've tried connecting in download mode, nothing. I've tried the LG support tool, PC sync. Nothing.
WiFi does connect to the PC suite fine BTW and other than that the phone is working perfectly. I've also tried connecting multiple usb cables on multiple ports.
I haven't been able to find a single case of the same problem in the week or so i've been looking. Hoping someone can help, i'm thinking i may have soft bricked my phone. I really do not think this is a driver issue.
Any help would be great. cheers

YOu can try checking the device manager or use other USB port on your phone.

The problem is not like the usual ones you will see about "computer not being able to see device" I don't think it's a driver or software issue, or if it is it's unlike any i have found in the weeks i've been searching the net for a solution. Here's why....
When i connect the phone to Windows 7 and 8 ( on 3 different computers) No hardware is detected, nothing in the Device Manager, no yellow question marks indicating 'Unknown Hardware'. Nothing, all it does is start trickle charging.
Now even with no ADB, or any driver at all installed, the computer should still detect the phone. Mine does not.
The same thing happens using OSX and Linux Mint 16 (again multiple computers) No devices or mounted or volumes shown at all. Linux terminal command "$ lsusb" does not list my hardware.
This is why i'm pretty much convinced that there is something wrong with the USB port on the phone. Because, if Linux can't see it then surely it's a hardware problem right?
The only other thing i can think of is, i have messed up the phones firmware while trying to unroot it? but only because the timing of all this is just too uncanny.
I think i'll have to suck it up and admit defeat here. Funny thing is the phone works perfectly and charges fine.
Stuck on 4.2 , with no ADB functionality. Perhaps i'll sell it cheap to someone who doesn't care.
Cheers for the reply mate.
Same problem here!
Only my G2 is not rooted, it is still on factory OS and recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB ison on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definetly there seems to be a problem with the phone, but I don't beleive it's a software but a firmware problem.
Please help if anyone knows what to do.
same thing happened after installing T-mobile rom thrugh twrp. but my device boots into fastboot and i tryed falshing :
laf.img, boot.img, aboot.img, recovery.img, laf.img
but after reboot my LS980 dissapear from device manager and stucked on LG logo.
Dont know what to do now.
I'm no expert, but given there are a lot of them here and none have weighed in on this with any ideas for a fix, i'm going to assume it's a hardware problem.
Anyone else agree? Hardware problem not software?
Cheers
I guess that you already wiped everything right? Apart from that, i'll suggest you to go to some tech supp and ask them if they can verify that each pin of the micro usb is properly working.
Sorry for my english, hope it helps!

I will try to check the connector although i dont think that it is a hardware issue.
BTW I can enter the download mode after flashing the mentioned partitions and i can also enter the stock LG recovery but when i do the factory reset it keeps showing Factory reset processing ... for ever
It has happened to me the same thing :crying:, and is a problem with the boot.img, if by chance your G2 version 4.4.2 and the the 4.2.2 boot.img, goodbye.
The only solution is to take it to repair a service official, there will change you the card, with the consequent change of IMEI.quent change of IMEI.

I have some kinds of that problem, let try:
Settings -> General -> PC Connection -> Select USB connection method -> Media device (MTP) (or whatever)
Got this same issue after flashing cloudy g3 rom. Then later flashing dirty unicorns, which requires jelly bean baseband. But even restoring g3 and 24a baseband, still doesn't work. No pc tethering and no on the go usb. My usb port is basically charge only.

I have a LG G2 . recently updated from vs98027a to vs98039a 5.0 lollipop. Since the update my computer won't recognize my device in download mode and I don't have superuser ppermissions. Help plz
I also have the same problem.
It happened when I tried to backup info through LG PC Suite: the phone disconnected during the process, and now it's not recognized by any PC (http://forum.xda-developers.com/lg-g2/help/lg-g2-recognized-windows-backup-t3155323).
Also found a description of the same problem here: https://www.reddit.com/r/lgg2/comments/2urpnw/lg_g2_usb_only_charging_not_recognized_by_pc/ - no solutions, too.
Did anyone manage to fix this?
Hi Guys,
When updated my LG L5 E610v with LG Mobile support tool, it stucks in 'Download is in progress. Don not disconnect cable.
Tried a lot to fix this problem, no results.
I figured out that using adb, fastboot, PDAnet, LG suite, LG mobile support tool, kdz updater, a lot of different usb cables, button combinations, shake the phone, etc, my pc (and all software I used to connect) do not recognice my phone properly or not. For example: using adb, i get: device not found, etc.
I installed the right lg usb driver properly and see on device manager 'Modem' and 'usb device' installed. Seems to me, no proble at all !!!
Who wants to help me to figured out this problem ??? To say this, I am a noob with this problem.
Thx in advanced,

Dear all, I'm new here and just got my yotaphone 2 today, bought it locally from UAE, i beleive that the build ME refers to Middle East, got an android version of 4.4.3 YD201 model.
I thought that YD201 models are OTA updatable versions but seems not
Please can you guide me in a simple way how to update to lollipop? Noting that I've never flashed or done this before
Thank you so much..

You can follow this guide fully but you don't need to flash HK first, so you just flash RU 5.0.0 firmware directly.

Thank you so much.. Totally appreciate that.. But I don't know if it really matters as the tools relates to YD206 while I have YD201.. Should I proceed ?
By the tools do you mean YotaphoneFlasher? It works on both 201 and 206 since it's from official.
Thank you again.. OK I'm all set everything is ready but the only thing that's keeping me is drivers installation... Somehow the Google drive coming with the flasher is not being installed. I tried all ways possible, I.e. right click on the INF file and install but I get error message, and also tried to install it from device manager but couldn't. Can you please help with this? Thanks again
Btw I'm using Windows 7

my dear friend, i managed to update the driver, thanks to you, but it seems that when i power off the phone and enter the "downloading " mode on the phone screen then connect it to the computer it seems the phone is not being connected.. i used the flasher chosed option 1 "flash the cellphone" then i get the message "waiting for device" on the flasher..
i had a screenshot just to show that i have done everything i should (i guess) .. i.e. copied the firmware.. etc,,,
mindyou, i think the problem is that when i conncet the phone to usb it goes under other devices/Android which is not being recognized..
you are the best and thank you for your help again and again!
Weird. Do you've already install both drivers and restart your computer?
If yes, how about try to plug another usb port?
I got both ADB and Qualm drivers installed.. but nothing happening! I tried the 3 usb ports already..
I don't know how to solve this.. I think I need to try it on another computer .. maybe it'll work out!
Your driver not properly install. Try reboot pc, enable usb debugging at phone, plug in usb. See if there is any changes at device manager.
There is yellow triangle. So it mean.. Oh.. Oo..
If stilk not ok. Plug out usb from pc. At device manager, unsinstall both yellow triangle. Plug in back usb. So it will detect device and windows trying to install it.
If you have Windows 10 you have to disable signature driver verification, entering in the advanced boot menu of windows. After that the .inf driver will install.
I got the update at last and it's working beautifully smooth I downloaded universal driver from adbdriver.com and it worked perfectly. Thank you all guys for your help and efforts
