The first step is to boot into recovery mode. You should hold the Power and Volume Down buttons simultaneously and press and release each key when the Android mascot appears. After you’ve selected Recovery mode, you’ll be given a list of options. To start the process, you’ll need to choose the option to reboot the system. Press and hold the Power and Volume Down buttons together for a few seconds to enter recovery mode.
To install the Google app in recovery mode, you need to download an OTA zip file. You can find them in the download section on Google’s site. Once downloaded, you can transfer the zip file to the phone’s storage or SD card if you have one. Make sure the file is in an easily accessible location. Next, reboot the device into stock recovery mode. To do this, press the Volume Down button and hold the Power key at the same time.
Next, go to Settings > General>About Phone & Settings>System>System>Recovery>System>Recovery Mode. Then, find the Google Play Services app and click on “Storage & cache.” Now, you’ll have to click on “Clear data” to remove the cache and data from your phone. Make sure that you choose the correct option based on the device you’re using.
