Kernel Alfs

Esse é um dos mais conhecidos Kernel para o Xperia X8, baseado no nAa e lapidado, hoje em dia já segue sua própria ramificação e da um show em desempenho, é um kernel mais suave em suas transições e com muita performance, foi um dos pioneiros a utilizar o modulo de Dualtouch com Game MOD, existem 2 tipos de Alfs, o Alfs CM7 e o Alfs_GDX, Alfs_CM7 é utilizada basicamente em ROMs CyanogenMod7 e outras baseadas na mesma, servindo o exemplo para a Alfs GDX que é utilizada nas ROMs GingerDX e em ROMs baseadas nela, em desempenho e nas caracteristicas elas são iguais, o que muda é o modulo de WLAN, então se você tentou colocar um kernel Alfs em uma ROM e bugou o Wifi pode ser que o kernel esteja trocado, então é muito bom prestar atenção nos postes das ROMs e recomendações dos Kernels.
