AOSP via recoveryをインストールしてみた

(※端末が文鎮になっても責任は負いません。自己責任でお願いいたします。)

AOSPのリカバリー生成を行って、NexusGalaxyに入れてみました。
まずはこちらを読んでください。

An experiment: installing AOSP via recovery

いまのところ、GSM版NexusGalaxy(maguro)のみ可能です。
また、リカバリー生成を行う環境はmasterブランチです。
(android-4.0.3_r1では生成できません、失敗します)

以下、JBQさんが公開されたScriptに少し手順を加えたものです。
(※buildディレクトリにproprietary binariesの展開を忘れないように)

build情報はこんな感じ。
Android versionが「4.0.3.0.2.0.1.0」となっています。
4.3.2.1.0ってカウントダウンでしょうか。
