FIX 6: This Device Isn’t Play Protect Certified in Custom ROMs

This guide will show you the steps to fix the “This Device Isn’t Play Protect Certified” error when using a custom ROM. One of the biggest perks of using an open-source OS is the truckload of goodies that it brings in with itself. In this regard, the ability to flash customized firmware has always been the preferred tweak for the tech enthusiast. In this regard, before making their ROM public, the developers register it with Google.

This is a must if the ROM comes built-in with GApps, such as Pixel Experience. In cases, the ROM does come with GApps [LineageOS], the developers don’t take any chance and still register their ROMs. As a result, your device will be certified and you will be easily able to use the Google Apps, Services, and Frameworks without any issues.

Moreover, your device will be more secure now as the Play Store will continuously scan for harmful apps and notify you if it finds a malicious app installed. However, there have been a few instances wherein the developers don’t certify their ROM and as a result, the users are the ultimate sufferers. If you are also in the same boat, then fret not as this guide will show you the steps to fix the “This Device Isn’t Play Protect Certified” error when using a custom ROM.

   su

   

6. You will get a Magisk prompt on your device, tap Grant.
   
7. Now type in the below command to get the device’s ID

   sqlite3 /data/data/com.google.android.gsf/databases/gservices.db    'select * from main where name = "android_id";'

STEP 4: Register the Custom ROM
