Motorola Moto E — XT1021 brickado em 5.0.2

Povo, estou com um XT1021 velho de guerra que simplesmente parou de funcionar... Acabou a bateria, quando carreguei já entrou em bootloop, seguido de um Android com tampa aberta...

Tentei de todas as formas flashear a firmware, mas ele sempre dá erros, e não consigo resolver...

Se dou um "mfastboot getvar all", ele retorna:

Porém qualquer comando pra flashear a firmware stock de volta, resulta em:

mfastboot flash partition gpt.bin
target max-sparse-size: 256MB
sending 'partition' (32 KB)...
OKAY [ 0.055s]
writing 'partition'...
(bootloader) This may take a few seconds, if a
(bootloader) different partition table is being
(bootloader) flashed since we need to backup

(bootloader) Flashing primary GPT image...

Ou isso:

Alguém tem alguma idéia? Ou morreu mesmo?
