Bootloop no logo da sony

Pessoal, estou com um problema no Xperia SP que já estou pistola, peguei ele travado no logo da sony. Achando eu que seria fácil de consertar, tentei pelo Xperia Companion, mas o mesmo esta com bootloader desbloqueado. Tentei pelo Sony Mobile Flasher(Flash Tool) e ele da este erro:
