[Moto Z2 Play  Questions & Answers] stemonta:
Hello and thank you for your work, my motorola z2 play came into bootloop from scratch, when it was in stock configuration, then without active debugging usb, bootloader unlocked and being in bootloop I can't unlock anything or even install the official ROM , now I'm trying with Lenovo Moto Smart but I have little hope because the phone keeps turning on and off even when it's in recovery mode. Do you have any advice for me?

Sorry for the poor description but I'm not very experienced, I ask you for advice because I don't know how to do it anymore.

Thank you,

Stephen.

PS: I also tried to unlock the oem with the motorola code but without success

PSS: I copy the account of my tempted to flash the stock rom
