Ontem, tinha instalado o Android ICS 4.0.4. Hoje, saltei para o Jelly Bean 4.1.1! Maravilha!
Colmo gosto de transmitir as minhas experiências, informo que esta actualização do ICS 4.0.4 para o Jelly Bean 4.1.1 foi efectuada num Samsung Galaxy S2 (I9100) não tendo resultado nenhuma anomalia durante o processo de instalação do novo SO.
Em outros modelos não posso confirmar que resulte, por isso, atenção, apenas serve para o Galaxy S2 I9100…
Seguem o tutorial (em inglês) e as imagens que tirei ao meu S2.
