UbuntuでNexus 7 2012にAndroid 5.0 Lollipopをインストール

Ubuntu 14.04

oemロックを解除後、再起動すると、南京錠が外れたロゴが表示されるようになった。それとともに初期状態に戻ったのだが、再びgoogleアカウントでログインして、 USBデバッグモードにする必要があったので、再びこの端末(Ubuntu)でNexus7 2012と USBデバッグモードで接続できる状態にしておく。

でいよいよ、ファクトリーイメージを焼く。adb reboot bootloaderでブートローダーを起動する。

arimasou16@arimasou16-Peppy:~/android-sdk-linux/platform-tools$ sudo sh nakasi-lrx22g/flash-all.sh 
[sudo] password for arimasou16: 
nakasi-lrx22g/flash-all.sh: 17: nakasi-lrx22g/flash-all.sh: fastboot: not found
nakasi-lrx22g/flash-all.sh: 18: nakasi-lrx22g/flash-all.sh: fastboot: not found

nakasi-lrx22g/flash-all.sh: 21: nakasi-lrx22g/flash-all.sh: fastboot: not found
nakasi-lrx22g/flash-all.sh: 22: nakasi-lrx22g/flash-all.sh: fastboot: not found
nakasi-lrx22g/flash-all.sh: 23: nakasi-lrx22g/flash-all.sh: fastboot: not found
nakasi-lrx22g/flash-all.sh: 24: nakasi-lrx22g/flash-all.sh: fastboot: not found
nakasi-lrx22g/flash-all.sh: 26: nakasi-lrx22g/flash-all.sh: fastboot: not found

あれ・・・fastbootコマンドが実行できないとのエラーメッセージ。

つまりだ、sudoでは platform-toolsまで通したパスがリセットされてしまった。初め、 flash-all.shを編集しようかと思ったけど、正攻法(?)でいくことにした。

【Ubuntu】sudoする際にPATHをどう引き継ぐか - Qiitaを参考にさせていただいた。

今のユーザーグループを exempt_groupに追加することにした。

sudo visudoを実行し、以下のとおり編集した。

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults>       env_reset
Defaults>       mail_badpass
Defaults>       secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
Defaults>       exempt_group="arimasou16"

exempt_groupを編集。

そして、~/android-sdk-linux/platform-tools/nakasi-lrx22gにまで移動。そして、シェルを実行。

writing 'bootloader'...で失敗。そのせいか、最後までうまく行かない。

どうも調べるとNexus 7 2012の端末でOSが4.4以下の場合では、いきなり Lollipopを焼けないらしい。ということらしいので、 4.4 (KRT16S)Factory Images for Nexus Devices - Android — Google Developersから落としてくる。

そして、同じように platform-tools配下に展開する。

うまく行った。今度こそ、 Lollipopを焼けるはずだ・・・と、その前にまたNexus7が初期状態に戻っていたのでgoogleアカウントでログインして、 USBデバッグモードを有効にして、端末(Ubuntu)との接続ができる状態にする。

writing 'bootloader'...でまたずっこけたが、処理はそのまま継続されて、そのままファクトリーイメージは焼けた。その後、Nexus7 2012を起動させると、ちゃんと Lollipop(5.0.2) として起動できた。しかも、既存機能でアプリの復元ができて、あっという間に元に戻れた!動作も遅くなるようなことも、今のところない。
