Xiaomi device will end up with error if you’re flashing global ROM on locked bootloader. That’s why it’s very important to have it unlocked so you can manually update your Redmi 5 Plus into global ROM.
Before you begin, keep in mind that after successful registration for bootloader unlock, Xiaomi sets you up with a wait time up to 360 hours. There is currently no way around this and you have to sit it out.
