Guys, I need a little help here. I've rooted my share of phones, and even some tablets, but the Evo i bought a few days ago has been a nightmare.
For some reason, and I can't tell why, this thing will not be recognized by Windows.
It always shows up as "Unknown Device" under the USB catagory on Device Manager.
I've tried different OS versions (Windows 7 64Bit, Vista 64bit, Even Mac). I've also pulled down every form of driver I can think of (SDK Orginal version, HTC Sync, Hboot Versions, etc.)
I just cannot get this thing to be recognized. And if I manually try to update the driver and point it to one that I've downloaded, Windows tells me that the most current driver is already installed.
The bottom line is that I need to be able to connect to the phone from the comp in order to push stuff via ADB and throw commands at it. The same unknown device situation happens when the phone is in bootloader or actually booted into Stock Froyo (2.2)
Has anyone ever seen anything like this? I know i haven't, and it's buggin me out.

I've never seen that before. Wish I had something for ya. Is the Evo brand new or used? Are you sure the usb cable is good? I've seen a bad cable cause some headaches before. Wish I had more for ya, sorry man.
Sent from my PC36100 using XDA App
EVO is not new. I bough it from cragslist a few days ago. It seems to work fine otherwise. Not rooted for sure, and running Sprint original 2.2.
I did try a couple of different USB cables just to be sure, and had the same results.
The funny thing is that even though I was never able to get it "recognized" on any of my machines, I was able to get ADB so "see" it for a while. I started the rooting process by pushing files to it via ADB and even sent a reboot command to it.
Once it rebooted, that's when it all went bad. It was still showing as unrecognized (just like before), but now ADB can't see it at all. Keeps telling me no devices are connected.
Even my friend's Mac Air (which supposedly doesn't need any kind of drivers to see the phone) can't see it either.
It's just weird...
perform a hard reset, maybe a rogue app or setting got messed up,
fastboot screen>clear storage>yes
Tried that as well. Sorry i didn't mention it in the original post.
I think I've pretty much tried everything that's somewhat logical at this point.
Now I'm looking for the "illogical" ideas.
Make sure usb debugging option is turned on in settings>applications>development and the phone is in charge only mode. Then it should be recognized and you should be able to use adb.
Debugging was turned on already. I made sure of that.
As for the mode of connection I've tried them all with mixed results.
Here's what I've seen so far...
Charge only - unrecognized device in Device manager, and ADB can't see it.
HTC sync - unrecognized device in Device manager, and ADB can't see it.
Disk Drive - unrecognized device in Device manager, and ADB can't see it.
Internet Sharing - never tried it.
Here's the weird part. If i uncheck Debugging and set the phone to HTC Sync, I am sometimes able to get ADB to see it.
This is just confusing...
What happens if you uninstall HTC Sync and just leave the drivers installed? Could work I suppose. I know unrevoked says to make sure you uninstall HTC Sync and install the ADB drivers.
try this. connect your evo to a machine running xp. i had the same problems rooting one evo using windows 7. connected to a machine running xp ,zipped right through without a hitch.
HOPE THIS HELPS YOU IN YOUR QUEST
Thats what I tried on the Vista box.removed HTC sync, and left the HTC drivers.when that failed I removed the drivers too and replaced them with several different ones I found online.none seemed to work.
The strangest part is that all guides seem to say that MAC OS should just see it without any drivers.
I borrowed friends MAC air and it didn't see it either.
I'm not sure which USB drivers you are using, but these work for me. Uninstall the drivers first, then install this. I hope it is legal to put these here and if not I am extremely sorry.
PS you could try a Linux Live CD and it will see it without drivers or go with Wubi which installs Ubuntu on your Windows hard drive and can be uninstalled just like any other program. It gives you the option to boot into Ubuntu or Windows on bootup. Neat little program and it is faster than using the live CD. Go to this link Wubi and click the Start Download button to download Wubi.
Those seem to be the same drivers I've tried (well those and a ton of others as well).
I'm gonna give that LiveCD idea a shot. Burning it now.
If not, I'm gonna try to find an XP machine somewhere.
I've got a couple of VM's on my machine running XP, but since the main Win7 Machine doesn't see it, it can't seem to pass the USB connection over to the XP VM.
Man, I have to say, this is just the most complicated rooting process I've ever seen. If this was my first root attempt, I'm pretty sure I'd leave Android forever
It usually is a painless operation to root the Evo. For some reason you are having a difficult time with driver installation. It seriously has to be something simple that has been missed, because I have rooted mine and several friends Evo's and it was very easy. I had a MyTouch 3g 3.5mm before this Evo and talk about a pain. Before the Universal Auto root app you had to make a gold card first and that in itself took over an hour. It was my first root and it was very difficult and time consuming, so to see how easy the Evo was no matter which way I do it made me very happy.

yes the mac doesn't require additonal drivers to run adb however u need to make sure the directory is properly set in terminal so adb knows where to pull commands from... on windows did u try uninstalling everything phone related? SDK, HTC Sync, the whole nine yards then try reinstalling only the sdk and the usb drivers? I know with the lastest SDK the usb driver is not included for some reason or at least it wasn't with mine... then one day my adb just randomly stopped working and a uninstall/reinstall cleared up everything... try this usb driver and see where it gets u. Don't know if it's any different that wat the guy above posted but worth a shot. Reinstall the appropriate SDK first then i would recommend plugging the evo into the pc with no usb drivers installed then when it cant automatically find the drivers direct it to the file u downloaded and it should pull the necessary drivers from there and see if that does the trick...

No dice so far guys...but i have made progress in identifying the issue (sort of).
So here's the deal - the ONLY way the phone is recognized is if i toggle the "debugging" setting.
If i plug the phone in with the switch set on (meaning USB Debugging enabled) the phone is not recognized. Pointing the unknown device to the drivers (any drivers) does nothing.
However, if i plug the phone in with the switch set off, it finds a usb mass storage device. Then i turn the debugging switch on, and it finds the ADB Android phone with no issues. Then i can push commands via ADB without any problems.
The problem i have is that I cannot toggle that switch if i boot into HBOOT menu. So the comp never see's the phone.
I've tried this experiment on Win7-64bit, Vista-64bit, XP 32bit, and even MAC.
The same situation seems to apply everywhere, and with all of the drivers I've tried. None of them seem to allow the phone to be plugged in and automatically be found. The only way for the comp to see the phone is if i toggle the debugging switch off, then on.
At this point, I'm ready to put out a bounty on this. $20 via PayPal to anyone who can walk me through it. Bottom line is that I need to be able to see the phone without having to toggle the debugging switch. That will allow me to boot into HBOOT and still send commands to the phone via ADB.
Thanks for all the help guys. Hopefully, we can get this resolved.

Anyone care to take a shot??
Let me start by first saying I'm brand new to the forum and have never rooted, unlocked, or flashed anything, so I'm a total novice. Any help is therefore greatly appreciated! I have a VZW Galaxy Nexus, and I've decided to manually install a Jelly Bean Rom, rather than waiting for Verizon's slow ass. I'm trying to use Wug Fresh's Nexus Root Toolkit to do so, but I can't even get started because I can't get Windows to recognize the device when connected via USB. I know there are many other threads about this, but I can't seem to get a straightforward answer for my exact situation. I've installed all the drivers I can find - the official Samsung drivers, the drivers included in the toolkit, and some naked drivers found here on XDA. Nothing seems to work. I've tried it on three different machines - XP, Visa, and W7. The message I get when I try to manually configure/select the drivers is something to the effect that the most current software/driver is already installed, despite the fact Windows says there's no driver and doesn't recognize the device. Oh, and one last thing, I've now tried this on two different GNex's - Verizon just replaced mine for signal loss issues, and the new one has the new build number IMM76Q. I'm at a complete loss and extremely frustrated. Help!!!

Lol just be forewarned, a lot of douchebags may come in here and make fun of you. Ignore them, they don't represent XDA
I'm getting the Galaxy Nexus in a few days (mine's the Sprint one), but I'm going to be using mskip's GNex Toolkit. No worries, he has one for the Galaxy Nexus on Verizon too:
http://forum.xda-developers.com/showthread.php?t=1400871
I would download that and use it to install the drivers. If that doesn't work, mskip has a pretty extensive FAQ and I believe drivers on Windows is answered in the 1st solution in post 3...so follow the link, download THAT toolkit, see if the drivers install properly and if not, go to post 3 and follow the instructions for "fastboot drivers".
Next time, try to use the search bar please. It is a rule around here to do so because it's XDA, which means every question has been asked and answered a million times lol no big deal, just be more weary in the future!
**edit**
first post, huh? Welcome to XDA
The Universal Naked Driver is the one you want, it include the ADB FastBoot drivers required to do flashings (link in my sig). The Samsung driver from Samsung Kies is a different driver so the computer could recognize the phone storage.
Make sure you use the official USB cable or a quality one to get good connection. Uninstall all unncessary Android drivers from other devices and the Nexus too, reboot, connect the Nexus, when it ask for a driver poing it to the Universal Naked Driver folder. If the installation still fail, try a different computer.
Sometimws the Nexus might be attached to the wrong ADB driver, when you connect it, you can go to Device Manager and uninstall the ADB driver, but also selecting the option to delete the driver from the system.

Thanks both of you for your help so far. I tried installing these naked drivers but no still luck. I don't have any preexisting Android drivers on the computer, but how would I uninstall drivers on the Nexus? The message I get when I try to update the drivers to these is that Windows could not find a better match for the hardware than you currently have installed. I checked the Driver Details and the driver it has listed is C:\WINDOWS\system32\DRIVERS\klfltdev.sys. I've tried numerous times "uninstalling" the driver, rebooting the computer, and starting the process over again but still no luck. I'm unable to actually remove this system file from my computer. I've been trying to do this on a work computer running XP, but I tried the naked drivers on a Vista machine as well, and I still get a similar message about the software already being the best match when I try to point Windows to these drivers (again, no other drivers installed on that machine). I'm so frustrated...

I have done all of this, including following the complete instructions and trying all options at http://theunlockr.com/2009/10/06/how-to-set-up-adb-usb-drivers-for-android-devices/
Still nothing seems to work. I am at a complete and total loss, and am entirely discouraged. For the life of me, I can't believe it's so utterly difficult just to properly install device drivers on a developer phone.
Ok I am sure you have done this but thought I would check. USB debugging needs to be enabled so settings developer options then enable usb debugging.

Yes, I turned debugging on. Never hurts to check, though. I'd love for the solution to be something so simple that I just overlooked.
http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735
First of all, DO NOT USE TOOLKITS!
I know it is easier for you, since you are new to this rooting stuff, but trust me on this, 2/3 people who said their phone's bricked used toolkit instead of adb and fastboot method
Now with that out of the way, you can check if you got any other drivers installed by going to Control Panel->Hardware and Sound->Device Manager
From there, connect your phone via USB and see driver pop up. If it's something like "Android 1.0", uninstall that, and then install naked driver. If you don't see any driver pop up after connecting, just install naked driver (for me, when I checked USB debugging, Windows automatically installed Samsung ADB driver that works well for me.). If you see something like "Samsung ADB Interface Driver", you should be able to use adb commands and such.
If you don't have fastboot and adb files, make sure you do this step!: After that, you should download adb files, fastboot files (adb and fastboot files can be found from Efrant's attachment from this thread: http://forum.xda-developers.com/showthread.php?t=1626895), and Android SDK (If you already have SDK for some reason, just download adb file and fastboot file ). After downloading Android SDK, put the folder in somewhere easy to find. (C:\ directory should do it). Now, put adb and fastboot files inside the platforms file (that can be found from SDK folder)
Now you got files set, go to the directory where you put adb and fastboot files, shift+right click and then click Open Command Prompt Here
Type "adb devices" and if you see one device from the cmd, you are good to go
FINALLY! I got it to work. I turns out the problem was just the GD USB cord I was using. I had been using the OEM Samsung that came with the device the entire time, so I obviously had no reason to believe the problem was the cord, especially considering the device would still charge when plugged into the computer or the AC outlet. I just happened to purchase a cheapy Chinese charging station that came with a USB cord and that did the trick. I guess I just got a lemon of a cord the first time. I could've been saved so much aggravation, but oh well! I'm no running the latest BAMF Paradigm Jelly Bean ROM, and it's sweet! Thanks to everyone for the help and suggestions!

What type of drivers are there for the S3?
I understand that you need drivers installed on the computer for it to reecognize the S3
How many driver are there?
Are there any more aside from this?
Where can i download these drivers?
I think ADB has a driver for thisas well?
Thanks!

Here is the link to the Driver package for i747 and i747m (AT&T/Bell/Rogers/Telus) With this, you don't need Keis...unless you want to use Keis. Also, TRY a WINDOWS UPDATE after installing this driver package.
I found their to be side issues on my Win7 and XP pc's....too long a story. If you have issues, I will send you a link.

Thanks mad producer. Is this driver package all the drivers I'll need?
I noticed these drivers are from the samsung site.
Are there any custom drivers or drivers for rooted phone, on custom roms etc?
Are there different kinds/type, I recall reading about ADB drivers or ADB connections.
Can you also send me the link to the issues with the drivers?
Thanks a bunch!

If/when you need ADB (I don't use it) then just look around for ADB. I don't have a link for that.
When I first connected my S3 to my Win7, XP, 2nd XP machine, each one had an issue with the MTP protocol. This is what's used to transfer files to and from phone internal and external storage. I did my homework and massive experimenting and solved the issues. (pretty pathetic really) I just don't have a turn key absolute solution but here are some tips. Try one or all of these till it works...and it WILL!
(Backup your PC before attempting and use at your own risk)
XP
- plug your Ss in via usb
- install the samsung drivers
- after any/each of these steps, unplug/replug usb S3 to PC
- check Device Manager in XP for any Yellow exclamation marks. If there are none, then go see if you can transfer large files (eg mp3) to your S3 and back via USB
- if you can then your done
- if not, download this and install
- if it's still not working, (which I doubt) then update windows. After the Samsung drivers are installed on some windows machines, windows updates provides a specific update that helps. I watched it happen/work on 2 machines.
- still not working, get ready....sounds crazy...but install Windows Media Player 11. It is tied into the MTP framework somehow. This is the version I used
Win7
- plug your Ss in via usb
- install the samsung drivers
- after any/each of these steps, unplug/replug usb S3 to PC
- check Device Manager in Win7 for any Yellow exclamation marks. If there are none, then go see if you can transfer large files (eg mp3) to your S3 and back via USB
- if you can then your done
- if it's still not working, (which I doubt) then update windows. (remember to unplug/replug usb after.
- install wmp11 or higher
- if it's still not working, try this file (sorry...can't elaborate on it)
- STILL NOT WORKING...doubt it...but last chance, download this file and place it into c/windows/inf directory and reboot.
Ok - I'm looking for a top to bottom guide on how to get this working with my phone.
I'm wanting to install a new ROM on it to hopefully breath a new lease of life into my phone.
As I understand it, to do this I need to unlock the bootloader - and so on - and to do this using the official method I need to use the Android Debug Bridge.
I've downloaded the Android SDK - and run ADB.exe - but when I do "adb devices" nothing is returned.
I've tried assorted cables - assorted USB drivers and so on - but nothing seems to work.
So - I want to start from scratch - what do I need to do, to get a blank slate, to try again to do this.
What drivers do I need to uninstall to start again - and what should the process be, top to bottom to do this?
I assume the SDK files I downloaded is fine and working. (I've tried doing this on two different PCs - both Windows 10 though) and had the same results so I'm assuming the SDK is ok.
I've got a european H815 - which was updated to the most recent update available for the phone.
I've got Dev mode initiated on the phone with USB Debugging ticked.
Is there a specific order to do things?
Is there a specific order to initiating debugging so that it "catches"?
Does it matter whether it's on MTP or PTP or USB Tethering?
Any help would be greatly appreciated.
I think once I get this ADB thing sorted out, I should be ok, as I managed, back in the day to install several different ROMs on my old HTC Desire - and I never had this issue with that phone.
Please help!!!
PS - my PC is totally up to date with Win 10 updates too (which may well be a problem in itself)
So - I have tried the following LG Driver packages and none seem to work.
LGMobileDriver_WHQL_Ver_4.0.4.exe
LGMobileDriver_WHQL_Ver_4.4.2.exe
LGUnitedMobileDriver_S52MAN314AP22_ML_WHQL_Ver_3.14.1.zip
UniversalAdbDriverSetup.msi
When I "Inspect Devices" via Chrome - the phone shows up ok too.
The phone is recognised as being attached to the PC and can be seen on the PC in the various modes (MTP, PTP, Midi and when USB tethered I think).
When the phone is connected by USB and a disable and re-enable USB debugging, I am asked if the PC cccess my phone data and I click "Allow".
I'm stumped.
Had another go on a different machine - and again the same things were happening.
Ditched another driver - not even sure if I even installed a different driver - I wasn't taking notes thinking that nothing was going to work anyway.
It just would not catch on the ADB.
But then I tried switching between modes whilst connected and somehow it worked!!!!!
Bish bash bosh - now I've got an unlocked bootloader!!!
Now for the next steps to getting some custom ROMs installed.
Note: I think the biggest issue was the screen asking to always trust the computer - when I did the bootloader unlock - it wiped everything (which I'd forgotten about!!!).
Anyway - as it was like plugging a new phone when I just connected to my home PC - it wanted to install PC drivers, and when I activated debugging, it flashed up the screen with a certificate??? ie a load of letters and numbers - asking if I want to trust the computer. (I can't remember the proper name for the screen - but have seen some people refer to it on other posts on here).
I said yes - and bang - first try - ADB works.
My advice - for anyone trying to do something similar and having problems with ADB - get everything backed up to begin with - and then do a factory reset.
That'll most likely reset stuff on the phone, and make things smoother...
Hi there. Sorry if I sound dumb. I'm new to this whole thing and this was supposed to be my first experience with flashing custom ROMs and stuff like that. I was planning to get ready to install LineageOS on my Nexus 7 using a Windows 10 PC. Unfortunately, things quickly went south.
My first roadblock was the tablet not being recognised by fastboot. I checked online for a bit and from what I could gather, the solution was to install the Google USB drivers using device manager. I went into device manager, right clicked my Nexus 7 in "portable devices", selected "update driver" and chose the Google USB driver I downloaded from the official Android developers website. I'm not sure if this is relevant but the tablet was in fastboot mode when I did this. From that point on, my tablet is no longer recognised and it just keeps saying "device descriptor request failed" whether it's in fastboot or normal mode, and regardless of which USB mode I choose.
I tried uninstalling the driver, factory resetting, WugFresh NRT, and using different cables and USB ports. I checked for all sorts of solutions but they either didn't help or they require an unlocked bootloader (which was the very first thing I tried to do before finding out I needed to install the driver for fastboot to recognise the Nexus 7). Does anyone here know of a solution to get this working again? I'm completely stumped on what to do.
EDIT: I tested with a Chromebook and an old Windows 7 PC I had lying around. Neither could detect my Nexus 7 and the W7 PC even said it failed to install the driver as soon as I plugged it in. It seems that the driver update screwed up my tablet somehow and I have no idea how to fix it. I really don't understand how this could have happened considering I followed Google's own instructions for updating the driver.
Does anyone perhaps have a copy of the OEM driver for the 2013 N7 Wi-Fi (flo) model? ASUS don't distribute the driver on their website anymore and I'm out of ideas.

Review this thread and the solutions.
After you have fixed it, you can easily install a new custom ROM with two steps:
RESTOCK - installs USB drivers and unlocks it, latest official stock ROM
CROSS - various custom ROMs, 1-click installation, TWRP, incl root

Thanks for the response. I don't think I'll have enough time to try this today but I might as well ask. Do any of these fixes work without needing a USB connection to a PC, or if they do, do they require adb and fastboot to work? Because if so, I won't be able to use them since my USB data connectivity is completely busted no matter what I plug my Nexus into.

RESTOCK - installs USB drivers and unlocks it, latest official stock ROM
CROSS - various custom ROMs, 1-click installation, TWRP, incl root
Click to expand...
Click to collapse
I just ran the RESTOCK 1 script and it worked wonders! My tablet's USB connectivity has been fixed and as an added bonus, my bootloader is now unlocked. I'll be continuing the process in Linux on my Pixelbook since it doesn't require any driver installations as far as I know. Thank you so much! You're a life saver!
