HTC Dream(aka T-Mobile G1, Android Dev Phone 1)のsystem updateが来たので入れるか思案してみる
ふと画面を見てみると、Holiday phone updateが出たとの表示があった。本物なのかどうか、入れてよいのかどうか思案中。
画面
本物？
インストールした人の書き込みを見つけた。
Google LatitudeとVoice searchの機能が増えているよう。RC33と同等か？
JFv1.41を入れていたり、カーネルを入れ替えてたりする人が入れるとどうなってしまうのかは不明。
フルバックアップ
普段からMy backupでバックアップは取ってある。今回は慎重にnandroid-2.0でフルバックアップも取っておく。
nandroid-2.0をLinuxマシンに入れておく。
以下の手順でリカバリモードになる。
- 終話(赤)ボタン長押しでシャットダウン
- ホームを押しながら終話(赤)ボタンを押して起動
nandroid.shを起動。
