We've dropped a guide on how to set up ADB and Fastboot on your PC. In some situations, ADB or Fastboot might still not detect the device. In my case, ADB could detect the tablet fine but once in Fastboot, it was a dead end; Fastboot couldn't detect the tablet. It was quite weird that ADB could detect but Fastboot couldn't. If you find yourself in such a situation then it's likely that your version of ADB or Fastboot is too old for the device in question or drivers need to be installed differently.

What to do when ADB or fastboot won't detect your Android device


Follow the steps below to fix adb or fastboot detection problems


See the video below or @ https://youtu.be/1dYn31wdw-s


  1. After the ADB-Fastboot setup guide above, download Google Platform Tools @ https://www.hovatek.com/forum/thread-17104.html (No need to download the entire SDK). Use the adb and fastboot binaries in the platform-tools folder instead
  2. Download the latest Google USB Driver @ https://developer.android.com/studio/run/win-usb and update whatever the device gets detected as in device manager (while in ADB or Fastboot which isn't working) with the technique @ https://www.hovatek.com/forum/thread-16839.html. You select the Android bootloader interface.

Important Notice
  • If you encounter FAILED (data transfer failure (Too many links)) then try a more powerful USB port
  • Some people have reported that booting into fastboot using button combos (instead of ADB) solved it.

Video Transcript
Quote:There are times that even if you've installed your ADB fastboot drivers you still don't get detection when you run fastboot commands or even adb commands I'm going to give you an example. In this
case I'm going to run an ADB command I'm going to launch ADB. I'll do this by copying the address on my ADB folder and then cd ... so now I'm in the adb directory so I'm going to run this ADB command: adb devices .

Don't forget your phone has to be connected to the PC via USB cord and USB debugging enabled on the phone for it to have a detection. Now I have ADB detection so I'm going to boot this phone into fastboot and run a fastboot command so adb reboot bootloader This is going to boot my phone into fastboot so on the screen you will notice the blank screen and fastboot mode written somewhere on the screen so I'm going to run a fastboot command right now fastboot devices to check if I have detection.

As you can see, I have no detection. Now, when you encounter this kind of issue you have two options or two things to try. First off, you need to download the latest fastboot binaries. We have that at our forum so visit the Hovatek Forum, download the latest fastboot binaries and then retry running the command. If you still don't get a detection then you need to update the phone's fastboot drivers.

Now, to do that, you (still with the phone in fastboot mode and connected to the PC) launch device manager and then you look out for what the phone gets detected as. You'll find something like this under other devices Android this is what mine looks like. To confirm that, I'm going to disconnect the phone that should disappear. You can see it disappears. I'm going to reconnect the phone still in fastboot Now this is what you're going to be updating all right?

You need to have downloaded the updated Google USB drivers. We also have a link to that at our forum so check it out. This is what it looks like; the updated Google USB drivers. You are going to be manually updating your drivers to this so now you right-click this Android entry, select Update driver, Browse my computer for driver software, Let me pick from a list, Next, Have disk, click on Browse.

You navigate to the location of the USB drivers and select the Android_USB.inf file. Select Open, OK then you highlight Android bootloader interface, Next, Click on Yes anyway. Don't forget that if you are using a Windows 8 and above PC, you need to have disabled driver signature verification so Windows has successfully updated your drivers. You can click on close.

Now, you're going to re-run the fastboot command fastboot devices and I have a detection
