First, download the ADB binary straight from Google for your particular OS and extract it to a separate directory on your computer.
Next, install the proper driver for your particular phone.
Then, enable “USB Debugging” in Settings –> Developer Options. If you don’t see Developer Options, then you will need to enable it by going to Settings –> About Phone then tapping on Build number 7 times.
Finally, ensure that ADB is working by starting a command prompt in the same directory as the ADB binary (right-click –> “open command prompt here”) and run the following command:
adb devices
If you see your device’s serial number (and it doesn’t say unauthorized), you’re golden. If you see a pop-up on your phone asking you to grant your computer ADB access, then say yes. If you don’t see either happen, then try rebooting your computer/phone and re-plugging it into your computer. Otherwise, try re-installing the driver.
Sending the ADB Command to Enable Mobile Data Toggle
Once you’ve confirmed ADB is working, it’s time to run the command. First, enter the following command to enter ADB shell:
adb shell
Your terminal/command prompt should now show that you are within the shell environment of your device. Once you’re in, enter this next command:
settings get secure sysui_qs_tiles
This will output a comma separated list of names that represent your current Quick Settings tiles. Copy this list down (save it in your clipboard, to a text file, whatever.) If you do not save this list, all of your existing Quick Settings tiles will disappear in the next command. Next, enter the following command:
settings put secure sysui_qs_tiles "YOUROLDLIST,MobileData,Hotspot"
Where YOUROLDLIST represents the comma separated list of Quick Setting tiles that you saved just before and MobileData is the name of the Mobile Data Toggle, appended to the end of the original tiles list.
Hotspot is the name of the Mobile Hotspot tile. Note the comma between the old list and the two additions, MobileData and Hotspot, and also note the use of quotation marks. Basically, all we’re doing is appending the name of the Mobile Data and Hotspot toggle to the end of our original tile list.
Once you enter this command, you should immediately see the Mobile Data and Hotspot toggle show up at the end of your Quick Settings tiles. You can then re-arrange it as you please so it will appear on the first page. This toggle will persist through reboots, but won’t survive a factory reset.
