If your screen works but Android won't boot, use OTG + Mouse + Custom Recovery . If your bootloader is locked, you are out of luck – you need an unlocked bootloader to flash a mini recovery that can install APKs via Fastboot. Disclaimer: Modifying system partitions voids warranties and can permanently brick hardware. Always back up your data before using Fastboot commands.
We have all been there. You pick up your Android phone, only to find it stuck in a boot loop, screen shattered, or the OS corrupted to the point where the "Settings" app is a distant memory. In these moments, the usual method of installing apps (downloading from the Play Store or clicking an APK) is useless.
