If your device has the arm64-v8 architecture, try downloading the variant for armv7a. If one of the applications didn't install, it means you probably downloaded the wrong APK variant - go back and make sure you properly matched the CPU architecture and Android version. Once you have installed all four apps, reboot your device. Also, if you have an SD card, make sure to take it out during these installations. Open the apps in the below order, and when the installation is complete, press 'Done' and not 'Open.' Installing the apps out of order will cause the Play Store to not work. You should see all four APK files ⁠- if not, go back and figure out which one you missed. If you don't have a file manager, download the latest version of Files by Google from APKMirror and install it.

Find the Downloads/Files app on your device and open it. Now comes the final step: installing the Play Store. Thankfully, Google distributes the Play Store as a single variant that works on all architectures and Android versions, so just go to this page and download the latest version that isn't marked as 'beta.' After the APK file is done downloading, do not open it - we'll do that later. The last app you need to download is the Google Play Store itself. Again, don't open it after you're done downloading, because we'll do that later.

Once you find the variant for your device, select it and download the APK. For example, my Google Pixel is running Android 10 and uses the arm64-v8a architecture, so I would pick the APK for 'Android 10+' and 'arm64-v8a + armeabi-v7a.' The plus symbol means it works on both listed architectures.
