Hi hovatek,
I'm using an itel A13 plus and windows 8.1
It seems like I can't install google usb driver(android_winusb) on my windows 8.1 pc.

I have already disabled the driver signature verification and installed spreadtrum usb driver(SciU2S).
I also installed adb and put adb_usb file on .android folder and added 0*1782 on it.
Still I don't see my device listed on adb.I also tried kill-server and start-server command and still no responce.
My phone isn't asking for authorization confirmation.So I disabled developer option,disabled usb debug,restarted the phone and turned them on again.
Still same problem.I can't see my device on ADB.
I can see all other drivers are installed on device manager except for android_winusb
I have attached an screenshot of the error I'm getting while I try to install android_winusb.

I'm not a noob.So u can be specific on what I should do now.
Thanks

what do you want to achieve with the driver you want to install?
what's wrong with the phone and how did the problem start?
see https://www.hovatek.com/forum/thread-588.html for how to setup android ADB driver.

I will unlock my device bootloader.There's nothing wrong with the phone.I did download adb v1.4.3(15 seconds adb installer) from xda and set it up.

ADB is fine.Problem is ADB isn't detecting my phone.I can install all the spreadtrum usb drivers.I only can't install google usb driver(android_winsub.inf)

I guess that's why when I type -

i understood your problem very clearly, you've already installed the driver you need to connect with adb when you installed adb installer as you said you did in your first post and to confirm this,
launch device manager on the PC >> turn on usb debugging on the phone >> connect the phone to the PC >> check device manager if the device is detected and drivers installed properly or not (attach full screenshot)

in adb window, run the command "adb version" and also attach full screenshot

2 questions
1. Did you enable USB debugging on your phone
2. Does adb detect any other Android phone around you?

Please turn up your phone's brightness while watching these two pic I have just attached.

Please you check and tell me whether my device is showing on windows device management section and yes I sure did turned on adb debugging.
adb says the version is 1.0.32
Thank you

Edit : just now I updated to the latest adb and still things are same.
When I type -adb devices
It shows -
Daemon started successfully at tcp:5037
List of device attached
(None)



I guess problem is still somewhere with the drivers.I'm running Windows 8.1,its a ***** up windows version anyway.
I have installed device drivers for spreadtrum countless times.
Don't know what went wrong this time!

your problem is not spd drivers but adb drivers
uninstall all adb and fastboot driver using the guide @ https://www.hovatek.com/forum/thread-7660.html
reboot the PC then reinstall adb & fastboot using the the installer method in the guide @ https://www.hovatek.com/forum/thread-588.html
