Step 4: Run ADB command from your PC
On the PC, you need install Amazon Fire ADB driver and install Android SDK. Please follow this official guide for this.
Now connect your Amazon Fire tablet to the PC with USB cable.
As shown below, you need use 3 commands:
1. cd to the folder where adb.exe is located. For my PC, it is located in C:\apps\adt-bundle-windows-x86_64-20140321\sdk\platform-tools because I used the old zip package and unzipped it to apps folder. On your PC, the folder name should be different.
2. I need check whether the Fire tablet is recognized as an ADB device. The command is:
adb devices
The output of this command should be the serial number of your Fire tablet.
3, Now, run the ADB command to grant a new permission to Google Play services. The command is:
adb shell pm grant com.google.android.gms android.permission.INTERACT_ACROSS_USERS
There should be no output or errors.
