Samsung Galaxy S3 — tela travada no logo: erro wipe data/factory reset

Olá a todos!
Então, meu celular recentemente travou na tela do logo da Samsung. Tentei fazer o factory reset e não deu certo por causa da seguinte mensagem:

E:failed to mount /efs (No such file or directory)
E:failed to mount /system ((No such file or directory))

MANUAL MODE

Já tentei instalar rom e etc, sou leiga nisso e tento me virar com o que acho na internet, porém não encontrei nada esclarecedor a respeito desse erro em específico e então resolvi perguntar aqui. Se alguém puder me ajudar, eu agradeço!
