hello
eventullay you have a hardware problem cable or usb hub.... because even your drivers are not installed correctly the
device manager on your pc make instead of the phone named: android device 1.0 a yellow sign with eclamation mark if you don't have this, there is an hardware or a bigger ROM error.

i had this problem too. but this worked for me, i hope it works for you too.
Open My Computer
Right Click on it and select Properties
Select Device Manager
Right click Android. Click Update Driver Software
Manually locate the drivers and update.
I hope that works
if you can't find "android" maybe it's under USB, or something like that. it should be there.

[SOLVED]Xperia L Drivers And ADB Problems

Hi there
I have seen some posts where users are having difficulty connecting Xperia L to their PC or ADB. Therefore, I am writing this guide to help you all.
The guide was prepared using Windows 7 Ultimate but should work with Windows XP and Windows 8.
Firstly, Sony uses a different driver for their Xperia devices and therefore, sometimes you are unable to install drivers for your devices especially for ADB commands.
IF YOU ARE LUCKY
There are few ways to get around to install drivers for your device. The most convenient and easy is you plug in your device and wait for automatic detection of your device. Make sure you have USB connected as MTP in MY XPERIA in SETTINGS of your phone. The device drivers would be automatically installed by Windows update.
METHOD
If suppose you can not install your drivers, connect your xperia and then on your PC, go to My computer > Properties>Device Manager.
You should see an undetected hardware with a yellow exclamation mark over it. Open it and click on update my drivers. Then choose GOOGLE DRIVERS by choosing hard-drive. This should install the drivers for you. If this doesnot work. Try the attachment with the post where the drivers are modified to work with Sony Xperia Devices.
Follow the same steps but this time choose the attachment folder to search for drivers. It might say, the drivers are not verified. Just Ignore it and carry on installing them. You will need to unzip these files.
IF suppose you do not see any exclamation mark while you connect your xperia. Just go to control panel and add new hardware. Select, I will choose my device and then install from hard-disk. Select the folder where you have unzipped the files and you are good to go. The name of new hardware is not important as windows will read the drivers files and install drivers for Xperia.
This will install all drivers for your device. If there are two or more drivers while installing them. Redo the steps and install all of them individually.
Suppose your ADB still doesnot work, then
FOR ADB DRIVERS :
Download the ADB Universal Drivers and connect your device. Then hit install. The ADB drivers will be automatically detected and installed.
Further, if these tricks fail, you can delete the unknown driver from your control panel and then try finding it again by using refresh button(scan for new hardware changes) in device manager.
Another trick is to click on unknown drivers and delete them. Connect your phone and restart your phone. Then scan for new hardware in device manager. The drivers should be installed for your device.
If still there are some problems, I will try to help you out.

UPDATE :
Use flashtool drivers to install adb/fastboot/flashboot drivers. This is the most simplest and easiest method I have come across lately.
Simply download flashtool
http://www.flashtool.net/index.php
Go to folder where you have downloaded it. Usually C:/flashtool/drivers.
Select the drivers for your particular device. I use universal for all three types of drivers. It is helpful to boot into fastboot/Flashtool before installing the drivers but not necessarily.
Good Luck

Did you try the attached drivers ?
I am just wondering you might hadnot turned USB debugging or disabled MTP mode or something you might have done to your kernel/ROM that might have changed the environment of your phone which factory reset reverted back. These drivers are NOT the drivers for connecting your device to your PC. These are used when you are unlocking your bootloader or working with ADB/fastboot commands.
Thanks for your contribution about how it worked for you and it might help others who might have a problem!

you can use ADB Wireless

I had tried every possible driver haha! Also had everything like USB Debugging etc turned ON, I guess it might have been some app I had installed. Anyways now I have rooted it successfully.
Thanks a lot for your help.

I am still having this problem for days now. still no connection to pc/flashtool whenever i try to reboot into flashmode/flashboot. i've been google'ing around. and i've tried this method but it's seems doesnt work. i've already got tons of these unknown devices, and the driver doesnt work(or maybe im too noobish to install them).please help

For a second when I looked at your images, I was just baffled. THOSE MANY UNKNOWN DEVICES! That can't be right you know.
There must be only ONE unknown device that ought to be installed as mentioned above in my post.
Do you see these devices when you connect your phone to your PC or those unknown devices are already there?
Have you tried windows update to fix it?
Tell me more about why you see so many devices.
If suppose, they are already there, just see which device comes up when you connect your phone and try installing drivers for that particular device.
Also, i suggest just go for add a new device and then select hard disk and then install drivers which are attached. I hope that fixes your problem.
REMEMBER your device must be connected when you are trying to install the drivers

right.i'm gonna give it a try,wish me luck. thanks!

I still need your help!!
I could not install or might be dont know how to install the attached xperia drivers which are in .dll files. Can u explain in detail how can I install it. I've lost root access after upgrade to 4.2.2 . I do really need your help to get back root access and install a valid driver for my device. From C2104

just go to device manager, connect phone and find ur not recognized device; then right click on it and press update/install drivers. From the window that will appear choose socond option (it should be something like manualy find drivers or something like that), then navigate to that downloaded folder. This way it should install them
But XL doesnt need any external drivers. If u install fasboot an flashmode drivers from flashtool folder they should work; they are working for me and for anyone i know. U may also install SEUS and then connect phone. This way u dont need that drivers, but ofc what i have mentioned earlier should work.

Hi
well first thing you need to understand is there are three drivers you need to install to make everything work including fastboot , flashboot, and Xperia L storage and SD card.
To install each type of drivers, you must have the phone in that particular state. To install normal drivers (for mass storage and PC companion), if suppose not detected automatically, you need to turn on your phone and then unlock it. Then see if drivers are found or not!
If the windows give you the error like undetectable device attached, go to my computers and then properties and the device manager and look for any device with an exclamation mark (yellow).
click on it and then select update drivers and use drivers that have been attached in the first post. (Remember to extract the attachment in a folder)
Then click on select drivers from hard drive (click manual installation of drivers )
and locate the folder where you have extracted drivers. This will install drivers!
if you want drivers for flashmode/fastboot, turn off phone and boot into flashmode and then install drivers as I mentioned above.
I'm quite certain they wouldn't trouble you at all. If you still need help, do not hesitate to ask !
Good luck
P.S: You will need to enable developers option and select USB debugging to root your device. I hope you are doing that right !

you must boot your phone in fast boot mode. turn off your phone and hold down volume down when you connect it to the PC!
Use flashtool to flash ftf file. you'll need to place ftf file in C:/flashtool/firmwares
then select the right file for xperia L and just flash ftf.
in flash tool , select flash n then fastboot and then I'll ask you to put your phone in fast boot (use method mentioned above)
good luck !

I have tried all your methods
but I keep getting this error message "An error occurred during the installation of the device"

I`ll try to help you:
1. Download the 0.73 drivers from here http://forum.xda-developers.com/showthread.php?t=2386956 and extract the file once with 7-zip
2. Connect the phone to usb and in device manager (rightclick) delete all excisting drivers of the device and after that uninstalll the device.
3. De-connect and reconnect the device and prevent windows to search for drivers. Select the device and rightclick and select update drivers. Then choose to install drivers from the pc and choose the unzipped 0.73 file and click install.
That should work, you may have to reboot the PC sometimes.
Good luck bro.

If you connect the phone to the pc by usb and go to device manager and you rightclick on the Nexus 5 and choose update drivers. Choose the second option for installing drivers from the pc and select the unzipped naked drivers file, is that not possible?

[Q] right drivers

hello, I am trying to get my computer to recognize my xt901. I installed the modem and management drivers on my computer (win xp.) I get a window that wants to find the right drivers for my phone when I plug it in. It can never find the right drivers, and it is connected to the internet. What am I missing?

assuming it's a android device try this http://adbdriver.com/upload/AdbDriverInstaller.exe

Nexus 5 showing up as ACER ADB Interface Windows 8.1

Hi guys, I recently installed windows 8.1 and now my N5 shows up in device manager as ACER ADB Interface and I can't acces MTP , I didn't had this problem with windows 7 , it worked perfectly back than ( i have unlocked and rooted my N5 with windows 7 without any issues ) . What can I do to make it work with windows 8.1 ?

I had the same, you have to go into Device Manager and roll back the driver to the Google one. Proper PITA

I can't do it, the roll back option is grayed out

I have managed to make it work, nevermind .

I rolled the driver back, but it keeps updating to it. I've uninstalled and deleted the driver, yet it keeps reinstalling it. Somehow, my MTP connection started working again. Not sure how though. If I knew which KB update it was, I'd uninstall it from there.

The other option is to manually change the driver in Device Manager from the ACER one to the Google one. I think it's happened as M$ have the ACER driver digitally signed whereas the Google one isn't so it'll always choose the signed driver...

I'm not sure how to do that, because, of course, if you try to update it, it will say that the Acer one installed is already the best driver. And after uninstalling it, upon plugging it back in, it updates to the Acer driver automatically again.

You have to manually check and select 'choose from a list' and you'll see the MTP option as well as the Acer one. Select the MTP one and you're good to go

I can never seem to get adb or fastboot to work I gave up and dual booted my computer with Linux Linux hasn't given me problems with adb or fastboot
Sent from my Nexus 5 using Tapatalk

This worked for me
Hi guys, I had the same problem. My phone was configured as MTP but when i connected to Win 7 it would appears in the Device Manager list as "ADB", this wouldn't allow me to transfer files so what worked for me was:
1- Connect your Mobile to the PC and it appears as ADB Driver (In the device manager screen), rignt click on ADB and select Browse my computer for driver software.
2- Choose let me pick a from list of devices on my computer and choose the option MTP instead of ADB.
3- Did that and problem solve, hope this helps for you !!

Delete this Acer ADB driver when you uninstall it
I have the same issue. Here is what I did and that resolved the issue. Go to "Device Manager" to uninstall the Acer driver. The uninstall window pops up asking you if you want to uninstall it. There is a check box that says "Delete the driver." Make sure you check that off and then go ahead and uninstall it. Once that's done, plug your Nexus 5 back in. The correct MTP driver will now be installed and your computer will recognize the phone normally. Hope this helps.

Experiencing the same on Windows 7...have tried everything suggested
Really hoping someone can help because I've just about had it with this. I'm running Windows 7 Home Premium 64-bit. I have a brand new Nexus 5 16GB. As others have indicated, when I plug my phone into my computer with debugging enabled, it creates an "Android Composite ADB Interface" device listed under "ACER Device" in Device Manager. See attachment.
I have tried every permutation of the 'uninstall driver, manually install Google USB driver' solution, to no avail. The best way I can describe what I'm seeing is that Windows is forcibly categorizing the device as an 'ACER Device' even though the driver files themselves are telling it otherwise.
If debugging is DISABLED, and EITHER MTP or PTP is ENABLED, everything is just fine - the default Windows drivers for those devices kick in, and no 'ACER Device' category is created.
If debugging is ENABLED, and MTP and PTP are DISABLED, when I tell Windows to use the Google USB driver, it says that the device could not be installed.
If debugging is ENABLED, and MTP is ENABLED, the 'ACER Device' issue rears its ugly head even when I tell Windows to use the Google USB driver.
I've already disabled Windows automatically fetching a driver online, so that's not to blame.
If this is the result of a Windows Update, does anyone know the number of the update so I might try uninstalling it? I can't seem to find it despite searching.
Hoping someone out there can help. Thanks!
