XT 1078 - Não entra sistema - Liga direto no Fastboot

Olá Pessoal

Estou com o celular de um colega da empresa... que me entregou dizendo que do nada se reiniciou e agora só entra no fastboot...

Bem, ele (e nem eu) sabemos dizer com 100% de certeza qual era a versão do Android dele... mas tenho quase certeza que era o 6...

Já tentei de todas as formas que encontrei na net colocar a "stock rom" dele, tanto 5.0.2 como 6, e não vai... Acredito, que pelo fato do bootloader estar bloqueado.

Ao tentar desbloquear via "fastboot oem get-unlock-data" o aparelho retorna isso:
(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found
(bootloader) slot-suffixes: not found
...
(bootloader) Failed to get unlock data, please try again!
FAILED (remote failure)
finished. total time: 5.055s

Li que talvez fosse pelo OEM estar bloqueado... teria q ir nas opções de desenvolvimento e bla bla bla... ocorre que como eu falei, o telefone não entra no Android. Apenas em fastboot.

Quando dou comando pra dar erase ou format, o resultado é sempre algo como isso:
Formatting is not supported for file system with type 'raw'.

Quando eu tento usar as opções de flash (pra passar a rom stock), acontece mais ou menos isso:
