The after installing a GSI can take a very long time, sometimes up to 10-15 minutes, and the device may reboot once or twice. This is normal as the system is configuring itself. Do not interrupt the process.

: You cannot flash custom system images on a locked bootloader. This process varies by manufacturer (e.g., Mi Unlock Tool for Xiaomi, fastboot commands for Pixel/Motorola).
