Motorola Moto E (2015) — Falha ao flashear a ROM Original do Moto E 2015 - 2ª Geração 4G DTV (XT1023)

Boa Noite!

Recentemente, eu tentei fazer root pelo KingRoot e de repente reiniciou o aparelho em modo fastboot, não querendo iniciar o Android em questão. Pesquisei sobre este problema na web e baixei a ROM Original, instalei os drivers da Motorola e até tentei instalar pelo RSD Lite, pelo CMD, mas quando chegava na System aparecia este erro:

Eu tentei desbloquear o bootloader, mas não consegui pois tinha que permitir o OEM nas opções de desenvolvedor, e não tenho como fazer isso se não chego nem no Android? Estou tentando isso faz duas semanas!

Vcs podem me ajudar o mais urgente possível, por favor.

Obrigado.
