Hi, I'm trying to go back to stock rom following this guide but I can't get adb to recognize my phone (even if I've already used adb in this pc to unlock the bootloader and flash the custom recovery). I'm on Liquid Smooth ROM and my pc has Windows 8.1.
I tried uninstalling motorola drivers and reinstalling again and uninstalling and letting windows install the drivers automatically but no luck either way (and USB debugging is activated in the phone).
When I access to the device manager in the pc it shows a warning sign on Motorola ADB Interface saying the controllers for that device are not installed, that the manufacturer is unknown and that there aren't compatible controllers for the device (I'm translating what the pic says for those who don't understand spanish xD). I tried to uninstall that Motorola ADB interface thing but it remains there.
What can I do?
SOLUTION: See last post.
You'll need to manually install the driver for the unknown devices. Point to your motorola driver folder.
Are you on CM11?
I had the same problem, tried Motorola USB Driver, Universal ADB driver, Google USB driver and also editing the USB.inf to match the hardwareID.. none of that worked until I set the USB computer connection to Camera (PTP)
Good luck!

That same thing happens to me, if I put it in camera mode it does work, the problem is that I need it to work in fastbood mode and it doesn't recognize my device there

EDIT: I've found the solution, I noticed I had two Motorola ADB Interface controllers, one in "Android Devices" and the other in unknown controllers. I went to the unknown one and imported the same certificate the upper one had and now it works (though I have two Motorola ADB Interface in android devices).

In fastboot mode, I made the USB work by using Koush's Universal ADB driver.
But if you are using Windows 8 or 8.1, you'll need to turn off the forced signature verification before you can install the drivers, since they are not signed.
Well... glad you got it..

Go to device manager, you should see a device called "Android Device" (IIRC). Right click to update device drivers, select device driver, manually search for one but then pick choose from a list. You should be able to see the right driver that is normally used.
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 .

Why not actually post what you did to fix it so it can benefit others in the future? Just a thought...

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

Btw... thanks for your help.
I went through those steps, but on my system, the MTP driver wasn't listed as an option.

Hmmm, I've only ever used the Google drivers from the SDK until this stupid ACER one appeared. Managed to get back to it now so it's all good. Perhaps download the Google driver and then point to it?

Yeah , I forgot , sorry about that . I managed to make it work by downloading this drivers " https://dl-ssl.google.com/android/repository/latest_usb_driver_windows.zip " . After i have extracted the driver i plugged my N5 to the PC, than I went to the Device Manager i right clicked the Acer ADB Interface and I have selected Update Drivers . After that I selected the folder where i have extracted the drivers , than i chose " Let me pick from a list ... " , I selected MTP USB Device and Voila , it works !

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!
I have a Nexus 5 that I have had about a month now and I had the USB on it working before about a week ago. I plugged it in today and neither my desktop or laptop could recognize it anymore. Both computers are running Windows 8.1.1 and the issues seems to be new as I can neither get USB storage or ADB to find it. The closest I can get it to working is to switch the USB mode to PTP and it reads that but I don't want to pull photos off. When I have it in MTP, it makes the sound of it plugging in and my phone shows it is plugged into a computer but Explorer shows nothing and it says it is working normally in device manager. I've tried everything from enabling and disabling debugging, restarted both my phone and computer tried reinstalling the drivers (both by the computer automatically finding them and manually installing them) but nothing seems to work. Is it possible that Windows Update could of broke the drivers since my computer installed updates yesterday? I also have Linux on my laptop and it appears to read fine with Linux.
That's the exact issue. If you check in Device Manager you'll see it listed as 'ACER ADB Device' (or something like that). You have right-click on it, select update driver, manually check and go through the list option and choose the MTP driver and it'll work again (and with USB Debugging enabled if you don't usually have it on like me)
I theorise that it's happened cause the Acer driver is digitally signed and the Google ones aren't but I could be wrong. Either way, it's a PITA

OK thanks. I'll give it a try because it was showing up as ACER ADB Device under device manager
EDIT: I updated the drivers and used the USB composit drivers instead and it got MTP working again. When I set it to USB composit, it installed Google's ADB drivers and the Nexus 5's USB drivers so everything is working again. Thanks for your help

I can´t manually update driver because of this:
when i update the acer adb it says the driver is up to date and everything is all same. what to do?
Thanks! Thought I was going to go crazy. Worked for me...
i set the driver to MTP as mentioned above and the phone started to show up on the explorer but now i couldnt copy any files from my laptop to the
phone. It displays like that and if clicked yes then the copy wouldnt happen.what is the problem.
Uninstall driver, plug in device, tell windows to not auto install driver (or disconnect from internet), click to update or install driver, point to folder with drivers, install, all is done.

That msg comes when you're in PTP mode I think...Only certain formats are supported.
Check under storage, expansion menu and make sure you are set to the first option...not PTP.
Above guy mentioned to have phone in USB debugging mode when setting up drivers.
If the device is showing then you need to point to the drivers for it (download them from google). I reinstalled windows a few days ago and had the acer issue (device first shows up in device manager as nexus 5 then switches to acer), windows wants it to be an acer device. Stop windows and then install the correct drivers,
For me I had to click the auto install in windows tray and tell it to stop. After a few times it worked.
No I'm connecting in MTP mode. Ahh its gettn irritating.
Hey,
I have an ASUS X55A Laptop with Windows 10 and I can't connect any phone with it. USB Sticks etc work normally so I think it is a MTP related problem. My device right now is a Moto G. I connect it with the USB port and my pc detects it, but I can't get access to the data on the phone. I installed the motorola drivers manually, but it didn't work either.
When I am in the windows "device manager" I can see my phone, but I am not able to install the MTP drivers properly. There is a small warning triangle next to my device name.
I tried many things, but I can not find a solution. If it is really MTP/PTP related, how can I install the drivers properly and working?
Thx for your help.
Edit: When I connect the phone without any drivers installed it says "Device is being installed" and the bar is ca. 5% filled and is stuck there. So the MTP won't install automatically.
Solved:
I installed the "Windows 10 Media Feature Pack" and now it works. I had the N Version of Win10, so it was not preinstalled.
Thanks for your feedback

I cannot connect my DOOGEE Y300 to my Windows 10 PC as USB storage. The PC makes the usual sound when making a USB connection but the phone does not appear in Windows Explorer. The phone appears as "phone" in "Devices and Printers" but I have not been able to enable it. Has anyone else had this problem (and fixed it).

There should be a notification on the device when you connect it, pull that notification down and it might say its connected to device for charging, tap that notification and see if it pops another menu up with more options, select MTP for file transfer.

Hi I am a new member. I am also having the same problem with windows 10 and my y300. I have tried your solution but this still does not work. Has anyone had any success getting this working? Thank you.

Do you have the USB drivers for your device installed? The drivers that auto install when you connect to PC are not always enough. There should be drivers for your device brand that can be downloaded and installed manually.
Is your device recognized in device manager?
