Unbricking Vivo Y97 after flashing wrong recovery.img

It all started when I flashed the wrong recovery.img on my device. I have two Vivo Y97s with the exact model, version, and specs. I didn't realize that I need to port TWRP first on my recovery.img before I can flash it using fastboot. After I flashed the wrong recovery.img, my device suddenly wouldn't turn on, couldn't boot up, and couldn't even enter recovery mode. BTW, they are both bootloader unlocked and the other one is already rooted. Let's say A is the bricked phone and B is working fine. Can I use the backup ROM of B and restore it to A? I'm not gonna use stock ROM.
