Your Xiaomi Redmi 2 phone is stuck on the logo. The phone boots usually after reinstalling MIUI 8 or 9 Global Stable ROM, but the Google Play Store app is missing. Also, the factory reset can be the cause of the Google Play Store disappear even though you find pre-installed other Google applications.
Do we have to install TWRP custom recovery and root the phone to add the Play Store app? No requirement. What we need is the Google Play Store installer in the APK (Android Package Kit) format.
