一番新しそうな以下をもらって展開する。

これはOTAなので、全部入りというわけじゃなさそう。
systemしか入っていないし。
果たして、この状態から動くもの作れるのかね？
META-INF/com/google/android/update-*あたりがOTAの実体なんだろうな。
META-INF/com/google/android/update-binary META-INF/com/google/android/update-script META-INF/com/google/android/updater-script
update-binaryは実行ファイル。あとの２つはテキスト。
スクリプトファイル読むと、OTAの勉強になりそうだけど、このへんはまた機会があったら。
root@debian:~/gtv# cat ota.prop ro.ota.version=5
ほー、何かチェックに使っているのかな。
boot.imgは直置きね。
build.propはこんな感じ。

ヒープサイズが超でかい。
HD画像用か。
このへんが起動関連か。

recovery.img小さいなぁ。全部はいってなさそう。
chromeでgtk入っているのね。うざいよ。
system/chrome/lib/gtk-2.0/2.10.0/
pangoってなんだっけ？
テキストのレイアウトとレンダリングするフレームワークだっけか。
system/chrome/lib/pango/
このへんが問題のQt。これもうざい。
system/netflix/usr/local/qtc/imports/Qt/labs/
