MOTO X PLAY COM ROM APAGADO E BOOTLOAD BLOQUEADO

Olá pessoal, gostariam que me ajudassem por avor.

Eu não não gostei do Android 6.0 e quis voltar para o 5.1 seguindo o tutorial que existe aqui no fórum:https://www.nextpit.com.br/forum/669269/motorola-moto-x-play-stock-rom-xt1563

Fiz todo o procedimento e este foi o resultado:

Como podem ver, a ROM original foi apagada e não foi gravada a stock, pois o bootloader estava bloqueado (infelizmnete esqueci de desbloquear anteriormente) e o tutorial não pedia para desbloquear...

Tentei desbloquear o bootloader, peguei o código no site da Motorola porém, também deu a seguinte falha:

(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
finished. total time: 0.013s

Não consigo desmarcar opção pois a ROM foi apagada no processo anterior.
O que eu posso fazer?

Quando o celular tenta inicializar não aparece nem mais o logo da Motorola e sim uma tela vermelha. Ainda consigo entrar na tela de bootloader e realizar comandos mas é só isso até então.

Caso não seja mais possível nenhum tipo de ação, quanto acham que me cobrariam pra resolver o problema ou trocar a placa mãe em uma assistência?

Desde já obrigado a quem puder me ajudar, estou meio "desesperado" =(
