You can’t really flash phones without unlocking the bootloader first, and you can’t unlock the bootloader without unlocking FRP

Without opening the phone up and directly accessing NAND storage, you’re not going to be able to reflash much. This makes it impossible for most thieves to abuse custom ROMs to sell stolen devices, because there’s not that much profit in stolen phones if you need to spend hours on making them work again. You might as well get a real job at that point.
