A última linha mostrada acima está lá por mais de 12 horas sem mais nada. Não sabe como proceder.
Alguém sabe de uma solução alternativa?
Você pode tentar limpar o cache local usando este comando: 'ubuntu-device-flash --cleanup-cache touch'.
Depois disso, basta executar novamente o comando flash.
Se não é a primeira vez que o seu UbuntuTouch piscando? Então tente sem a opção '--bootstrap'.
