Boot CWM by volume keys

私が使っているCWMと通常起動を分岐させるスクリプトです。
起動時に音量キーを連打するとCWM起動になります。

bootイメージを展開して/initを/init.origにリネームし、代わりにこのスクリプトを/initに配置します。
busybox環境を/binに配置します。
CWM起動用のramdiskをtarで固めて/bin/recovery.tar.gzに配置します。
また、/bin/_suを配置しておくと良いと思います。

SH-04EとSH-06Eはexecでinit.origを実行すると何故か電波を掴まないので、CWMを起動しない場合はreboot recoveryします。
この機種は通常起動のブートイメージをrecoveryに焼いて下さい。
