[Moto Z Play Questions & Answers] Rohan_sadhwani:
I recently unlocked my bootloader and now i want to relock it.

I used this thread for relocking:

https://xdaforums.com/moto-z-play/how-to/guide-relock-bootloader-to-lasted-stock-t3718190

But now at the end it says

still need signed boot.img.

Please help me.
