First, let's test to make sure that we have working connectivity over ADB (Android Debug Bridge).
Open a commandline and type
In order for frida to work, we need it's companion
frida-server, to be running on the device. You can download it from the frida releases page on Github - make sure you get the one ending in "android-x86".
Push it to
adb push frida-server-12.8.20-android-x86 /data/local/tmp
Obtain root with
adb root, then connect to your device with
adb shell. Navigate to the /data/local/tmp directory with
cd /data/local/tmp .
At this point I prefer to rename frida-server to something a little less annoying to type:
mv frida-server-12.8.20-android-x86 frida-server
Make the server executable with
chmod 777 frida-server
Start the server with
nohup ./frida-server &
